O objetivo do estudo foi verificar a estabilidade do ato de locomoção em diabéticos com neuropatia periférica, em três situações: marcha habitual com os olhos abertos; marcha com os olhos fechados e marcha com olhos abertos e diminuição da base de sustentação. Participaram do estudo 41 indivíduos, sendo 18 do grupo neuropata e 23 do grupo controle (GC). A avaliação da estabilidade foi realizada por meio de um baropodômetro associado ao software Footwalk Pro. Os dados obtidos foram: velocidade da marcha e porcentagens de tempo de duplo apoio e de apoio simples. Foram encontradas diferenças significantes nas três situações entre os grupos para a velocidade e tempo de apoio simples, com diminuição para o grupo neuropata (p<0,05), e tempo de duplo apoio, com aumento para esse grupo (p<0,05) em todas as condições. Para os dados de velocidade, tempo de duplo apoio e tempo de apoio simples, a condição de olho aberto foi diferente da condição de olho fechado (p=0,001) e da condição com diminuição da base de sustentação (p=0,001). Foi possível observar que nas três situações avaliadas, o grupo neuropata apresentou déficit na estabilidade do ato de locomoção e tal desempenho foi ainda mais comprometido nas duas situações que exigiam mais do controle postural. Tais modificações da marcha, decorrentes da complexidade imposta pelas diferentes condições, sugerem a inserção destas na avaliação e no tratamento dessa população
The aim of this study was to verify the stability of the act of locomotion in diabetics with peripheral neuropathy in three situations: habitual gait with eyes opened, gait with eyes closed, and gait with eyes opened and reduced base of support. The study included 41 subjects: 18 of the neuropathic group and 23 in the control group. The stability was evaluated by baropodometry platform associated with the software Footwalk Pro. Data were obtained: gait speed and percentual of double stance time and single stance time. Significant differences were found in the three cases between the groups in the data of gait speed and single stance time, with a larger reduction for neuropathic group (p<0,05) and increased in double stance time in the neuropathic group (p<0,05) in all conditions. For data of gait speed measure, double stance time and single stance time, the condition eyes opened was different from eyes closed (p=0,001) and from the condition with reduced base of support (p=0,001). It was observed that in the three situations evaluated, the neuropathic group showed stability locomotion deficit and the performance was more injured in both situations that required more postural control. Such gait modifications, due to the complexity imposed by different conditions, suggest the inclusion of these in the evaluation and treatment of this population

Full textAutonomic neuropathy (AN) is a common and serious complication of diabetes. Early detection is essential to enable appropriate interventional therapy. Dynamic pupillometry has been proposed as simples and more sensitive tool to detect subclinical autonomic dysfunction. Moreover, the effect of actual glycaemia on autonomic function in diabetic subjects is unknown. The aims of this study weere: 1) to investigate pupil responsiveness in diabetic subjects with and without cardiovascular autonomic neuropathy (CAN), and in diabetic subjects with and without diabetic peripheral neuropathy (DPN) using dynamic pupillometry and, 2) to study the correlation between the pupil responsiveness in diabetic subjects and the actual glycaemia. In the first study, two tests were applied. during the first test, one flash was administered and the pupil response recorded for 3 seconds. In the second test, twenty-five flashes at one-second intervals were administered and the pupil response recorded for 30 seconds. Several time related parameters were computed from the results. A total of 36 diabetic subjects and 22 healthy volunteers took part in the study. Our results show that diabetic subjects with and without CAN, and with or without DPN have sympathetic and parasympathetic dysfunction evidenced by diminished amplitude reflexes and significant smaller pupil diameter. It suggests that pupillary autonomic dysfunction occurs early, before a more generalized involvement of the autonomic nervous system. In the second study, only the first test was applied in 4 diabetic subjects at three levels of glycaemia. Our results show that the pupil responsiveness is not affect of actual glycaemia. Dynamic pupillometry may provide a simple, inexpensive and non-invasive tool to screen high-risk diabetic patients for diabetic autonomic neuropathy.

Full textThe use of Fuzzy expert model could be an interesting approach to enable a better distinction among different stages of diabetic sensorimotor polyneuropathy, and differences in muscle activity and in the time when these changes start occurring could be elucidated with this classification. EMG alterations during gait, supposedly caused by this disease, are subtle and still not consistent among authors, possibly due to difficulties in defining homogeneous experimental groups with clear definition of the disease stage of each subject. By classifying diabetic patients from absent to severe neuropathy with fuzzy logic, it clarified that muscle activity changes begin even before diabetic neuropathy is established , with delays of up to 31% in vastus lateralis peak activity at early stance and anticipation of 16% in tibialis anterior onset during terminal stance. The presence of diabetic neuropathy aggravates the changes in tibialis anterior, with 33% earlier onset time, and delayed peak activity at heel strike. Muscular alterations seem to be caused by structural and physiological changes in muscle tissue itself, caused by accumulation of advanced glycation end-products due to poor diabetes control, and these alterations become worse with the onset of neurological impairments when diabetic neuropathy is established

Full textDiabetes, a major public health problem, is associated with a number of metabolic risk factors that contribute to a high rate of micro- and macrovascular events. The mechanisms that contribute to the onset and development of these complications are poorly defined. Diabetic neuropathy (DN) is the most common complication of diabetes worldwide, affecting up to 50% of all diabetic patients. Diabetic Peripheral Neuropathy (DPN), the most common type of diabetic neuropathy is associated with structural changes and functional injuries affecting the peripheral nerves. The myelination of axons is a complex process carried out by Schwann cells (SCs) in the peripheral nervous system (PNS). However, the mechanism leading to nerve demyelination in diabetes is not well characterized. Peripheral myelin genes MPZ and PMP22 expression is tightly regulated in SCs. A slight change in PMP22 or MPZ expression has a deep impact on the development and preservation of nerve fibers and their myelin sheaths. The importance of glucose in the pathogenesis of DPN has been described. However, the cellular and molecular pathways involved in DPN are still unknown. The data obtained during my PhD show that the oxysterol/LXR pathway, involved in the myelination process, is deregulated in diabetes. The alteration of the LXR pathway was paralleled by an increase in the levels and expressions of the NADPH oxidases Nox1 and Nox4 leading to an increase in ROS production. In parallel, our group and others have also described the role of mTORC1 pathway in the progression of diabetic complications. Yet, the exact mechanism of mTORC1 activation is not yet fully described. We hypothesize that oxidative stress generating ROS, secondary to alteration in the levels and activities of selected NADPH oxidases is altered through an LXR dependent pathway, and contribute to the onset and progression of DPN. The resulting oxidative stress leads to the alteration in the signaling of the mTOR pathways culminating in alteration of the expression of myelin genes, and Schwann cells injury. From a fundamental perspective, this project will allow the identification of novel molecular mechanisms involved in DPN and from the clinical angle it will allow the development of effective therapeutic strategies to reverse or slow the progression of DPN

Full textDiabetes mellitus (DM) is considered a public health problem which can affect people\'s quality of life (QoL) through the consequences of its complications, such as peripheral neuropathy. Research on Health-related Quality of Life (HRQL) investigates and evaluates the impact of diseases and their treatment in people\'s life. Among the specific instruments of HRQL for DM, NeuroQol was identified for evaluation of the QoL of people with peripheral neuropathy and ulcers. This methodological study aimed to carry out the pilot stage of cultural adaptation and validation for Brazil of the NeuroQol instrument. NeuroQol has 35 items, of which 27 are distributed into six domains, Pain, Loss/reduction of sensitivity, Diffuse sensitive-motor symptoms, Limitations of daily life activities, Disorder in social relations and Emotional affliction. The process of adaptation followed the steps recommended in literature. Data were collected in an outpatient clinic of a public teaching hospital in the interior of the state of São Paulo, through interviews, physical examination and consultation of patient files. The sample consisted of 50 people, according to inclusion/exclusion criteria, between October 2009 and May 2010. The following psychometric properties were initially analyzed: face and content validity (board of experts); convergent construct validity (Pearson\'s correlation tests among the NeuroQol domains and the two SF-36 components); discriminant construct validity (Student\'s t test of NeuroQol among the group of people with ulcers and without ulcers); reliability (internal consistency - Cronbach\'s alpha). Results showed that most participants were female (58%), average age of 55 years; 70.6% had low educational level; average DM time of 16 years; 62% presented altered fasting plasma glucose and 66% glycated hemoglobin higher or equal to 7%. The convergent construct validity had negative correlations in the evaluation of the psychometric properties, with most correlations from moderate to high magnitude. As to the discriminant construct validity, the comparison of the averages of the instrument among groups with and without ulcer was significant in the domain Limitations of daily life activities. Reliability showed an adequate value for internal consistency of the adapted version of NeuroQol (Cronbach\'s ? =0.94). The adapted version of NeuroQol to Brazil is valid and reliable, in the studied sample. There is need to widen the psychometric analysis in samples which involve a higher number of participants.

Resumo: A doença diabetes em sua fase inicial é conhecida por induzir dor neuropática, como resultado de complicações neurovasculares mediada pela via diacilglicerol/ Proteinoquinase C (DAG/PKC). Considerando que a neuropatia induzida pelo diabetes está associada com diferentes isoformas da PKC, o objetivo deste estudo foi avaliar a expressão de diferentes isoformas da PKC nas condições dolorosas induzidas pelo diabetes tipo 1 na articulação temporomandibular (ATM) de ratos. Ratos Wistar (± 150 g, 2 meses de idade, n=4-6/grupo) foram tratados com uma injeção intraperitoneal de tampão citrato (veículo; normoglicêmicos ¿ NG) ou Estreptozotocina 75 mg/kg (diabéticos ¿ DB). As alterações dolorosas induzidas pelo diabetes tipo 1 foram avaliadas através da mensuração do comportamento nociceptivo dos animais induzido por uma injeção intra-articular de formalina 1,5% ou capsaicina 1,5% nos dias 7, 14, 21, 28, 35 ou 42 dias após a indução do diabetes ou veículo. Após a avaliação dos comportamentos nociceptivos, os animais foram mortos por anestesia e o tecido periarticular removido para análise de Western Blot. A fase inicial do diabetes tipo 1 induziu uma hiponocicepção na ATM dos ratos 7, 14, 21, 28, 35 e 42 dias depois da indução do diabetes (p<0.05: Two-way ANOVA, Bonferroni¿s test). Os animais diabéticos tratados com uma injeção intra-articular de capsaicina demonstraram hiponocicepção 7, 14, 21 e 28 dias depois da indução do diabetes (p<0.05: Two-way ANOVA, Bonferroni¿s test). A análise por Western Blot demonstrou que a expressão das proteinoquinases PKC-?1, PKC-?2, PKC-delta e PKC-epsilon no tecido periarticular foi significativamente maior nos ratos DB em comparação aos animais NG (p<0.05: Two-way ANOVA, Bonferroni¿s test), enquanto a expressão da PKC-? no tecido periarticular foi significativamente menor nos ratos DB em comparação aos animais NG (p<0,05). Os resultados sugerem que a hiponocicepção induzida pelo diabetes na ATM de ratos está associada à variação da expressão das diferentes isoformas da PKC: -?, -?1, -?2, -delta e -epsilon
Abstract: Diabetes in early phase is known to result in painful neuropathy as a result of neurovascular complications mediated by the activation of Diacylglycerol/Protein kinase C pathway (DAG/PKC). Considering that diabetes-induced neuropathy is associated with different PKC isoforms, the aim of this study was to evaluate the expression of PKC in diabetes type 1-induced pain condition in the temporomandibular joint (TMJ) of rats. Wistar rats (± 150 g, 2 month-old, n=4-6/group) were treated with an intraperitoneal injection of citrate buffer (vehicle; normoglycemic ¿ NG) or Streptozotocin 75 mg/kg (diabetic ¿ DB). Diabetes-induced pain conditions were assessed by the animals¿ nociceptive behavior induced by an intra-articular injection of 1.5% formalin or 1.5% capsaicin 7, 14, 21, 28, 35 or 42 days after the diabetic induction or vehicle. After behavioral assays, animals were terminally anesthetized and their periarticular tissue removed for Western Blot analysis. Early phase of diabetes type 1 induced hyponociception into TMJ of rats 7, 14, 21, 28, 35 and 42 days after the diabetic induction (p<0.05: Two-way ANOVA, Bonferroni¿s test). DB animals treated with an intra-articular injection of capsaicin demonstrated hyponociception 7, 14, 21 and 28 days after diabetes induction (p<0.05: Two-way ANOVA, Bonferroni¿s test). Western Blot analysis demonstrated that the expression of PKC-?1, PKC-?2, PKC-delta and PKC-epsilon into periarticular tissue was significantly higher in the DB rats than in the NG rats (p<0.05: Two-way ANOVA, Bonferroni¿s test), whereas the expression of PKC-? into periarticular tissue was significantly higher in the DB rats than in the NG rats (p<0.05). Early phase of diabetes type 1 induce hyponociception into rats TMJ that involves changes in the expression of different kinds of PKC isoforms: -?, -?1, -?2, -delta and -epsilon.

Full textThe aim of this work was to investigate the influence of diabetic neuropathy and the clinical history of plantar ulceration in the somatossensorial plantar sensitivity and in kinectic and electromyographic lower limb variables during gait of diabetic neuropathic subjects with (UDG) and without (DG) history of plantar ulceration. The casuistics was composed by 45 gender and age matched adult subjects, who were divided into three groups: DG - diabetic neuropathic group (n=19), UDG - diabetic neuropathic group composed by diabetic neuropathic subjects who presented at least one foot ulceration in the past two years (n=10), and a control group (CG) composed by non-diabetics asymptomatic adults. The results of somatossensorial tests showed a gradual loss of plantar sensitivity with the neuropathy progression. Subjects from UDG had worse plantar sensitivity than the DG. UDG also showed higher total contact time than DG (CG=693,1 ± 65,98; DG=681,5 ± 51,2; UDG=758,5 ± 105,1, in miliseconds). These numbers indicate that UDG subjects have a longer exposition time of the plantar surface to the pressures made by the contact with the ground durint gait. There was a gradual reduction of the vertical GRF second peak, from CG to DG, and from this last group to the UDG (CG=1,09 ± 0,06; DG = 1,05 ± 0,08; UDG = 1,02 ± 0,06). The main electromiographic changes found in UDG were: a delayed peak of activation of vastus lateralis muscle, right after the heel contact (CG=10,82 ± 3,33; DG=11,97 ± 2,31; UDG=14,83 ± 3,53,% of contact time), and a delayed peak of activation of gastrocnemius lateralis muscle (CG=63,53 ± 3,65; DG=62,84± 5,06; UDG=68,00± 4,78,% of contact time). These biomechanical changes suggest that diabetic neuropathic subjects with history of foot ulceration have a muscleskeleton system inefficacy during the shock absorption phase and during the propulsion phase of the gait. Although there were no significant differences in tibialis anterior muscle activity, DG subjects showed higher TA EMG activity, which suggests a compensatory mechanism to diminish overload on the forefoot during flat foot phase. The biomechanical changes found, associated with other sign and symptoms of neuropathy, like the loss of sensitivity, could be considerate predisposable factors for plantar ulcers formation or its recurrence.

Full textThe diabetes mellitus remains a problem with increasing incidence in the entire world, getting epidemic proportions in present time. This fact is followed by the increase in complications. The foot complications in these patients represent the highest morbimortality levels. The loss of protective sensibility is a preponderant factor in the appearing of foot ulcers in diabetic patients. Thus, the diagnostic methods must have elevated sensitivity, reproducibility and must quantify the disease stage, so specific procedures can be established. The author did a cross-sectional study, with the objective to determine the cutaneous sensibility thresholds in diabetic patients recruited from Hospital das Clinicas, Faculty of Medicine, University of São Paulo, with ulcer in only one of the lower extremities, comparing the thresholds of the member with ulcer with the member without ulcer. The sensibility was evaluated using the Semmes-Weinstein monofilament, the two points discrimination test with the disk-criminator(TM) and the PSSD (Pressure-Specified Sensory Device(TM)). An instrument capable to determine in a quantitative manner, reporting results in g/mm2, the exact pressure at which the individual can feel a touch in their skin, and to measure the pressure at which two points can be distinguished from one point touching the skin. The PSSD was used in four areas in patient\'s lower extremities: great toe pulp, dorsal feet, medial heel and lateral calf. The test was realized in four manners 1 point static, 1 point dynamic, 2 points static and 2 points dynamic. A total of 20 patients were included in the study, average age 61,6 years, average diabetic time 12,4 years. All the patients reported positively with the Semmes-Weinstein monofilament test. The mean of 2 point discrimination test was higher in the feet with ulcer, thus the results had statistic significance only in the hallux and lateral calf. All the patients reported cutaneous pressure thresholds higher in the feet with ulcer when comparing with the feet without ulcer, in both static and dynamic tests, with statistic significance in the four areas measured. As the conclusion, the PSSD was capable to differentiate the cutaneous thresholds among the extremity with ulcer and the extremity without ulcer in diabetic patients.

Full textThe human gait is one of the most studied movement in biomechanics. Its considered a repetitive cycle which is characterized by a stance and a swing phase. Gaits disturbance were found in patients with diabetic disease who have diabetic neuropathic foot. Some researchers found differences during the patients gait with diabetic neuropathic foot. The purpose of this study was to analyze comparatively in diabetic patients with and without neuropathic foot. The casuistic was composed by 36 subjects divided into three groups: CG - control group (n=10), DG - diabetic group (n=10) and DNG - diabetic neurophatic group (n=16). All subjects had their gait analyzed by capturing the vertical ground reaction force and recording the ankle joint range of motion. In order to analyze the data, a routine was developed and using Matlab® program. The results showed that the 1st. and 2nd. vertical ground reaction force peaks are statistically higher in diabetic patients with diabetic neuropathy and the ankle range of motion is statistically lower in this group. Hence, it can be concluded that vertical ground reaction force and the ankle range motion have different characteristics among the studied groups. Actions to reduce the vertical ground reaction force and to increase the range of the ankle joint motion are necessary in order to decrease the probability of developing foot ulcer

Full textThe diabetic neuropathy is one of the main chronic complications of Diabetes Mellitus which causes damage to somatosensory and motor control systems resulting in biomechanical alterations in locomotion patterns. Locomotion activities with greater mechanical and balance demands might be considered a risk factor for ulcer formation in diabetic neuropathic patients. Therefore, to have a better understanding of the diabetic neuropatic interference in the daily life of these individuals, it is essential to evaluate the biomechanics of lower limbs during real life activities. The aim of this study was to investigate the influence of the diabetic neuropathy in the discrete characteristics and in time series of muscle activation patterns, using superficial EMG, and sagittal kinematics, using electrogoniometers, of lower limbs during stair management in diabetics (n=23) and non-diabetic individuals (n=23). The discrete analyses were done by discrete variables of VL, GM and TA linear envelopes and the sagittal angular variation of hip, knee and ankle. These variables were compared between groups in each motor task, by t test for independent samples ( = 0.05). The analyses of electromyographic and sagittal angular variation time series were performed by cross-correlation of each serie between groups. Moreover, the strength of the phase relationship between muscle activity of VL, TA and GM with the angular variation of knee and ankle was assessed in each group. The correlation coefficients of these relationships were compared between groups by independent t tests ( = 0.05). The main findings showed that during the stair ascent, diabetics had lower ankle extension at the end of stance phase, and while projecting their body forward during the first half of stance, their ankle flexion angle was also smaller. Because of that, there was a worse ankle positioning in the beginning of the stance, necessary for an efficient action of VL. The mechanical disadvantage of VL observed in diabetic neuropathic patients at the beginning of the stance phase may have triggered an increased activation in the same muscle at the end of stance in the contralateral leg. In the stair descent, diabetics had lower ankle extension at the beginning of stance, but did not show significant alterations in EMG. In the time series analysis, the EMG signals of all muscles presented higher similarities in timing across time series between groups for stair ascent and descent. The correlation obtained between groups for the muscle activity and angular variation amongst all evaluated relationships were statistically lower in the diabetic group for stair ascent (for VL-knee and GM-ankle (both groups presented weak relation), except for the relation between TA and ankle joint variation, which was moderate for the diabetic individuals and weak for controls. In the stair descent, the correlations were similar between groups (moderate relation for VL- knee and GM - ankle, and a weak relation for TA - ankle). Apparently, the stair ascent explicited motor deficits caused by diabetic neuropathy in the discrete analysis and also in the time series analysis. Although the similarities in the time series in the stair descent, qualitative shape differences were observed, suggesting a impaired pattern of motor recruitment in neuropathic patients. In summary, diabetic neuropathic individuals presented an altered ankle kinematic and VL and TA muscles activities patterns during these real life activities, and also altered coordination between muscle activity of knee and ankle and adjacent joint motion. These facts, combined to higher vertical impacts of stair ascent and descent might raise the plantar ulceration risks in the daily activities of diabetic neuropathic individuals

Full textThe aim of the study was to develop and validate the content of free and easy to use software that customizes an exercise routine for feet and ankles, according to individual physical abilities, for people with Diabetes Mellitus. Diabetic foot orientation software (SOPED) was created in its web and mobile versions in the HTML, Javascript and PHP languages, and based on gamification principles. For the creation of this software, three main pillars were considered: a) foot care recommendations and information about diabetes; b) self evaluation of the feet according to the main occurrences of the diabetic foot (calluses, cracks, deformities, tissue lesions); and c) exercises for feet and ankles for muscle strengthening, gain of range of motion and improvement of functionality. Each exercise was defined with an average of 8 levels of progressive difficulty, which differs in the number of sets and repetitions, body positions and materials used. The individual progression is based in an algorithm that adjusts the volume of the training according to an effort analogic scale. It allows to maintain, progress or return the level of the exercises. After elaborating the exercise protocol to compose the tool, as well as all its contents, a prototype version / first version of the software was created and was submitted to a validation process to make it valid and reliable. Validation was performed through the Delphi technique, which consists of obtaining suggestions and approval from experts, in this case, professionals specialized in the care of diabetics (multiprofessional team, n = 9), and simultaneously from users with diabetes (n = 20). Data analysis was performed by simple descriptive statistics, using absolute and relative frequencies, mean, binomial test and content validity index. In the first round, experts and users evaluated the adequacy of content and clarity of the information of the prototype version of the software, elaborated by the researchers, according to a Likert scale, obtaining an average of 89.7% approval by the specialists and 90.3% by the people with diabetes. The second round consisted of approving or not the changes made in the second version of the software, according to the suggestions from the first round. A minimum approval of 70% has been established for the validation of the final version of the software. We obtained, in the second round, an average of 97% approval by the jury of people with diabetes and an average of 100% approval by the jury constituted by health professionals, so no further rounds were necessary.Thus, the conclusions point out that SOPED was developed with a high agreement between health specialists and users. It can be an effective tool to facilitate self-monitoring and self-care, besides containing specific exercises resembling a conventional therapy. It assists in the independence of prevention and treatment, and has the main benefit of progressing according to the possibilities of each patient, which is a situation closer to a supervised therapy. The software is free and has potential to be inserted into the public health system, especially for primary and secondary health care services as a complementary treatment for the feet and ankles complications associated with Diabetes Mellitus

Abstract: In addition to acute complications related to hyperglycemia, patients with Diabetes Mellitus develop several chronic complications throughout life that together contribute to greater morbidity and mortality in these individuals. Peripheral Diabetic Polyneuropathy (PND) is one of these complications, which, in addition to symptoms of paresthesia and hyperesthesia, and several types of spontaneous pain, can lead to a decrease in postural balance and an increased risk of falls. Objective: We performed a systematic review to evaluate the effectiveness of pre-programmed and supervised physical activity in the complementary treatment of PND. Methods: General and adaptive search strategies were created for electronic databases in the health area; Embase, Medline, CENTRAL-Cochrane, Lilacs, and PEDro. We included randomized trials in which patients with PND were allocated to participate or not in a pre-determined and supervised program of physical activity. The primary outcomes were: number of falls, improvement in the risk of falls (measured by the Functional Reach Test (FRT), Get Up and Go Test (TUG), Berg Balance Scale (BBS), stabilometry, and one leg stance test) and improvement in fear of falling (measured by the Fall Efficacy Scale International – FES-I).

Full textThe role of hyperglycemia in the pathogenesis of chronic complications of type 1 diabetes (T1D) is well established; one of the mechanisms proposed to explain its deleterious effects is the increased formation of advanced glycation end products (AGEs). AGEs irreversibly alter macromolecule structure, compromising its biological function. In addition, AGEs interact with its specific receptor RAGE (encoded by AGER) leading to the generation of reactive oxygen species (ROS). The AGER1 receptor (encoded by DDOST) counteracts RAGE signaling by stimulating cellular antioxidants and reducing inflammatory stress. An enzyme of potential interest is sirtuin 1, a deacetylase that plays an important role in the response to stress and to toxic compounds that may have their activity decreased in diabetes, being negatively modulated by AGEs. The Thioredoxin (TXN) system is a major endogenous antioxidant system; TXN is able to interact with several proteins, such as TXN interacting protein (TXNIP), implicated in the pathogenesis of diabetes and its complications. There are few studies addressing the expression of AGEs receptor and its association with microvascular chronic complications in T1D. The objectives of this study were to evaluate mRNA expression of the genes encoding RAGE (AGER), AGER1 (DDOST), sirtuin 1 (SIRT1) and TXNIP (TXNIP) (quantitative RT-PCR with the use of TaqMan probes) in peripheral blood mononuclear cells (PBMC) of T1D patients with diferent degrees of microvascular complications (retinopathy [DR], cardiovascular autonomic neuropathy [CAN] and nephropathy [DN]). The results of the target genes were normalized by the mean expression of two housekeeping genes (beta 2-microglobulin and beta actin). A total of 130 patients with T1D was sorted into two groups: Group A: patients without microvascular chronic complications or presenting mild non-proliferative DR (n = 68; 61.7% female; age 33; age at diagnostic 12; DM1 duration of 19 years, HbA1c 8.1%, data expressed as median), and Group B: patients with at least one of microvascular complication (moderate/severe non-proliferative DR or proliferative DR or CAN or ND; n = 82; 66% female; age 33 years; age at diagnosis of 11 years; duration of T1D of 21 years, HbA1c 8.2%; data expressed as median). Smokers were excluded from the study. Differences between groups were analyzed by Mann-Whitney test and correlations between continuous variables were assessed using Spearman\'s test. T1D patients presented, respectively, higher and lower relative expression of TXNIP (p<0.001) and DDOST (p=0.01) in comparison to the control group. In the analyses considering diabetes complications, TXNIP expression was higher in Groups A and B (p=0.01 and p=0.04, respectively) versus the control group. Patients with proliferative or moderate/severe non-proliferative DR (n=44) and also patients with mild non-proliferative DR or without DR (n=86) presented higher TXNIP expression versus the control group (p=0.0012 and p=0.01, respectively). Patients without (n=104) and with (n=46) CAN presented higher TXNIP expression than the control group (p=0.03 and p=0.04, respectively); finally, concerning estimated glomerular filtration rate (eGFR), both the group of patients with values <60 mL/min and < 60 ml/min presented higher TXNIP expression versus the control group (p=0.01 and p=0.005, respectivamente). Patients presenting DN (n=44) had a lower DDOST expression in comparison to patients without DN (n=107) (p=0.031) and to the control group (p=0.011); patients with eGFR <60 mL/min also presented a lower expression of DDOST in comparison to the control group (p=0.03). A positive correlation was observed between expression of SIRT1 and AGER (? Spearman=0=51; p < 0.0001) and between expression of SIRT1 and DDOST (? Spearman=0,51; p < 0.0001). The expression of TXN positively correlated with the expression of TXNIP (p Spearman=0.65; p < 0.0001), SIRT1 (p Spearman=0.41; p < 0.0001) and DDOST (p Spearman=0.23; p 0.004). In a subgroup of 30 T1D patients, a higher expression of the gene encoding RAGE was observed in those patients consuming a diet enriched in AGEs (p=0.03). Expression of TXNIP in PBMC is affected by the metabolic abnormalities of T1D but does not reflect the presence of microvascular complications while expression of the gene encoding AGER1 seems to reflect diabetic kidney impairment since it is decreased in patients with DN and in patients with an eGFR < 60 mL/min/1.73m2

Full textWe investigated the participation of sympathetic activity in the regulation of Slc2a4/GLUT4 expression in skeletal muscle of diabetic Wistar and spontaneously hypertensive (SHR) rats, treated with saline, insulin, propranolol and propranolol+insulin. Insulin reduced glycemia, urinary volume and glucose, and increased body weight and Slc2a4 expression in soleus, but decreased it in EDL. Propranolol reduced arterial blood pressure in SHR, and did not alter the metabolic parameters, increased the mRNA expression in EDL, but reduced it in soleus of normotensive rats. Propranolol+insulin showed that in soleus the effect of insulin was preponderant, whereas in EDL propranolol attenuated the insulin effect. The Slc2a4 expression was higher in SHR (soleus, EDL), and it was similar to the protein expression, with some discrepancies, indicating post-transcription regulation, or Tnfa-related alteration. In conclusion, the impairment in Slc2a4 expression during diabetes is limited in SHR, probably because their high sympathetic activity in skeletal muscle.

Dos oito estudos potencialmente elegíveis, apenas seis foram incluídos nessa revisão. Um total de 390 pacientes foi aleatoriamente designado para a intervenção ou grupo controle. Puderam ser plotados na metanálise o medo de cair pela FES e o risco de quedas pelo apoio unipodal, EEB, TAF e TUG. Favoreceram a intervenção o medo de cair e o teste do apoio unipodal com olhos abertos e fechados (MD -2,97, IC: -5.37, -0.57, I2=0%; MD 3.73 IC: 0.64, 6.83, p=0.02, I2 = 0% e MD 1.23, IC: 0.31, 2.16, p=0.009, I2=0%, respectivamente). Não houve diferenças significativas entre os grupos para os demais desfechos analisados. Conclusão: a atividade física pré-programada e supervisionada em indivíduos com PND foi eficaz na melhora do equilíbrio estático e diminuiu o medo de cair. A qualidade da evidência de acordo com GRADE para esses dois resultados foi moderada, o que significa dizer que há moderada confiança na estimativa de efeito e que o verdadeiro efeito esta próximo ao estimado, porém, existe a possibilidade de ser substancialmente diferente.

The fear of falling through the FES and the risk of falls through the one leg stance test, BBS, FRT, and TUG were plotted in the metaanalysis. The intervention favored the fear of falling and the test of one leg stance test with eyes open and closed (MD -2.97, CI: -5.37, -0.57, I2=0%; MD 3.73 CI: 0.64, 6.83, p=0.02, I2 = 0% and MD 1.23, CI: 0.31, 2.16, p=0.009, I2=0%, respectively). There were no significant differences between the groups for the other outcomes analyzed. Conclusion: Pre-programmed and supervised physical activity in individuals with PND was effective in improving static balance and decreasing fear of falling. The quality of the evidence according to the GRADE for these two results was moderate, which means that there is moderate confidence in the estimated effect and that the true effect is close to the estimated; however there is a possibility of it being substantially different.

Full textINTRODUCTION: Factors associated with the etiopathogenesis of diabetic complications, including hyperglycemia and oxidative stress, may cause epigenetic changes that modify the expression of genes in target cells without altering their DNA sequence. The following mechanisms are considered epigenetics: (1) post-translational modifications of histones; (2) methylation of DNA and (3) action of micro-RNAs (miRNAs); all have already been recognized in the pathogenesis of \"metabolic memory\", a situation in which hyperglycemia exerts prolonged deleterious effects even after its normalization. Sirtuin-1 is an enzyme that causes post-translational modifications of histones by their histone deacetylase activity, silencing gene transcription. Gene silencing may also occur through the action of DNA methyltransferase 1 (DNMT1), an enzyme that adds a methyl group (CH3) at position 5 of cytosine residues located in CpG islands from gene-promoter regions. miRNAs are a class of small non-coding RNAs with about 19 to 25 nucleotides that control gene expression by promoting translation repression or degradation of target messenger RNAs. The hypotheses of the present study are (1) there is a serum profile of miRNAs associated with the presence or absence of chronic complications and (2) there are variants in genes related to histone deacetylation and cytosine methylation that could predispose to diabetes complications, which would constitute the \"genetics of epigenetics\". OBJECTIVES: (1) to characterize and compare the serum miRNA profile of patients with type 1 diabetes mellitus (T1D) without any microvascular complications versus those with three microvascular complications: diabetic retinopathy (DR), diabetic kidney disease (DKD) and diabetic neuropathy to identify signaling pathways epigenetically modulated in these two groups of patients and (2) to assess the frequency of single nucleotide polymorphisms in the genes encoding DNMT1 and sirtuin-1 and their associations with each of the microvascular complications in T1D patients. METHODS: The serum profile of 381 miRNAs was evaluated using the Taqman® Human MicroRNA Array A kit in 10 clinical and laboratory well-characterized patients divided into two groups: Patients without microvascular complications: without DKD (creatinine clearance> 90 ml/min/1.73 m2 and urinary albumin excretion < 20 mg / g creatinine), without distal sensory-motor polyneuropathy (absence of symptoms suggestive of neuropathy and normal thermal and pain sensitivity and Achilles reflex), without cardiovascular autonomic neuropathy (CAN) and without DR; and T1D patients with complications: with DKD (creatinine clearance < 60 ml / min / 1.73 m2 and urinary albumin excretion> 200 mg / g creatinine), with distal sensory-motor polyneuropathy, with CAN and with DR moderate or severe. The five most differentially expressed miRNAs were validated in a well-characterized case series of 20 patients with no complications and 27 patients with all microvascular complications using the TaqMan (TM) Advanced miRNA cDNA Synthesis kit. The evaluation of the frequency of single nucleotide polymorphisms in genes encoding the DNMT1 (rs8112895, rs7254567, rs11085721, rs1729414, rs10854076) and sirtuin-1 (rs10997870; rs12766485) was performed by genotyping using real-time polymerase chain reaction in a sample of 466 T1D patients. RESULTS: Of the total of 377 target miRNAs evaluated in the serum of T1D patients, 21 miRNAs were overexpressed in the group with complications. Of the 5 miRNAs for which validation was performed in 47 patients, two were confirmed as overexpressed in the group with complications (hsa-miR-518d-3p and hsa-miR-618). The polymorphism rs11085721 in the gene encoding DNMT1 was associated with the presence of CAN in female patients, with the minor allele C being considered of risk and conferring an odds ratio (95% confidence interval) of 2.44 (1.26 - 5.28). Polymorphisms in the gene encoding Sirtuin-1 did not associate with microvascular complications. CONCLUSION: the serum miRNA profile differs between patients with and without microvascular complications. A variant in a gene encoding a enzyme of an epigenetic pathway conferring susceptibility to a chronic complication suggests that there is also the \"genetics of epigenetics\" modulating the development of complications

Full textIntroduction: The general proposal of this study is to get a better understanding on how motor control is affected in diabetic polyneuropathy (DPN) individuals. Fluctuations of the force and sEMG signal during isometric voluntary contractions have been studied as a simplified model of the physiological mechanism that underlies the control of movement. The analysis of the muscular recruitment patterns from lower limbs, obtained by high-density sEMG, together with the corresponding force signal outputs from knee and ankle joints, in the light of complexity analysis, adds to the knowledge of the disease effects in motor control. Additionally, examining the complexity of force and muscle activity of DPN individuals, along with the development of DPN from subclinical to the more severe stages, will help us understanding how the alterations will develop with the DPN progression. The hypotheses of this study are that: DPN alters the motor complexity, expressed as an increased amount of variability and a decreased structure of variability in sEMG and force outputs, and these alterations are aggravated by the severity of the disease. Methods: We assessed 10 control subjects and 38 diabetic subjects, classified as absent, mild, moderate, or severe DPN, by a fuzzy-system based on clinical variables. Multichannel sEMG (64-electrode matrix) of tibialis anterior, gastrocnemius medialis, vastus lateralis and biceps femoris muscles were acquired during isometric contractions at 10%, 20%, and 30% of the maximum voluntary contraction, and force levels were recorded during dorsiflexion, plantarflexion, knee extension and knee flexion. Standard deviation and sample entropy of force signals were calculated and root mean square and sample entropy were calculated from sEMG signals. Differences among groups of force and sEMG variables were verified using a multivariate analysis of variance (alpha=0.05). Results: Overall, during dorsiflexion contractions, moderate and severe subjects had higher force standard deviation and moderate subjects had lower force sample entropy. During plantarflexion, moderate subjects had higher force standard deviation and all diabetic subjects had lower entropy. During knee extension moderate DPN subjects demonstrated high force standard deviation and low force sample entropy. Tibialis anterior presented higher root mean square in absent group and lower entropy in mild subjects. For gastrocnemius medialis, entropy was higher in severe and lower in moderate subjects. Severely affected participants showed low sample entropy in vastus lateralis at all force levels. Conclusions: DPN affects the complexity of the neuromuscular system during low-level isometric contractions, reducing the system\'s capacity to adapt to challenging mechanical demands. The observed patterns of neuromuscular complexity were not associated with disease severity, with the majority of alterations recorded in moderate subject

Full textIntroduction: Peripheral (PN) and cardiovascular autonomic neuropathies (CAN) are prevalent complications of diabetes mellitus (DM). There are indications that their development occurs not only secondary to metabolic control. Thus, search for genetic predictors is very important. Several genes related to the biochemical pathways that lead to cellular damage induced by hyperglycemia have been investigated, emphasizing the genes related to the pathways of oxidative stress. The balance between antioxidant systems (such as glutathione and thioredoxin) and pro-oxidants (such as NADPH oxidase) is an important factor in cell defense against oxidative stress. Primary objective: to evaluate the association between the single nucleotide polymorphisms (SNP) of the mentioned anti-and pro-oxidant pathways and NP and NAC in type 1 DM patients: 718C / T in the 3 \'UTR (untranslated region) (rs713041) of the glutathione peroxidase 4 gene (GPX4); -129 C / T (rs1788390) in the glutamate cysteine ligase gene (GLCL); -1365 C / T (rs7211) in the thioredoxin interaction protein gene (TXNIP); -2810 A / G (rs6610650) in the CYBB gene; - 675 T / A (unregistered) in the CYBA gene. Secondary objective: to evaluate the relationship between different microvascular complications (neuropathy, diabetic renal disease [DRD] and diabetic retinopathy [DR]). Material and methods: 378 type 1 patients DM were selected from the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo and from Hospital das Clínicas da Universidade Estadual de Campinas; they had more than 10 years of disease and inadequate control (HbA1c > 8% at some period of life), and were examined for NP and NAC. Polymorphism genotyping was performed by real-time polymerase chain reaction (Taqman System®). Clinical, glycemic and lipid metabolism laboratorial variables and the presence of DRD and DR were evaluated. Also 257 patients were retrospectively evaluated regarding the evolution of the estimated glomerular filtration rate (eGFR) in relation to PN and CAN. The Pearson test was used to compare the frequencies of the genotypes and the magnitude of association was estimated by the odds ratios (OR), with the respective confidence interval (CI) adjusted by logistic regression for possible confounding factors. Results: The presence of at least one T allele at the SNP + 718C / T of the GPX4 gene protected for CAN (OR = 0.39; 95% CI 0.17-0.84; P = 0.0165). In the analysis of the association between complications, it was observed that: (1) in the presence of NP, there was an increase in risk of NAC (OR = 3.38; 95% CI 2.01 - 5.73; P < 0.0001), of albuminuria A3 (OR = 7.17; 95% CI 3.68 - 14.53; P < 0.0001) and of proliferative DR (OR = 9.58; 95% CI, 5.04 - 19.09; P < 0.0001) (2) in the presence of CAN, there was an increase in risk of PN (OR = 3.72; 95% CI 2.14 - 6.53; P < 0.0001), albuminuria A3 (OR = 9.37; CI95% 4.68 - 19.65; P<0,0001) and proliferative DR (OR = 3.30; CI95% 1.81 - 6.18; P < 0,0001).) In the subgroup evaluated retrospectively, the presence of PN and CAN was associated with a greater annual decrease of eGFR (-4.74 mL / min / year vs. -1.22 mL / min / year, P < 0.0001 and - 3.74 mL / min / yr vs. -1.54 mL / min / yr, P < 0.04, respectively). Conclusions: (1) the presence of the T allele at the SNP + 718C / T (rs713041) in the GPX4 gene confers protection for the presence of CAN in the studied type 1 DM population and (2) there is a risk association for PN and CAN among themselves and for severe forms of DRD and RD

Full textThis study aimed at investigating the influence of different stages of diabetic neuropathy in the muscle fiber conduction velocities estimated in four lower limb mucles during isometric maximal voluntary contraction using surface electromyography. Eighty-five adults were studied: 16 non-diabetic individuals and 69 diabetic patients classified into four neuropathy stages, defined by a fuzzy system: absent (n=26), mild (n=21), moderate (n=11) and severe (n=11). Average muscle fiber conduction velocities of gastrocnemius medialis, tibialis anterior, vastus lateralis and biceps femoris were assessed using linear array electrodes, and the studied groups were compared by ANOVAs (p < 0.05). Conduction velocities were significantly decreased in the moderate neuropathy group for the vastus lateralis compared to other groups (from 18 to 21% decrease), and were decreased in all diabetic groups for the tibialis anterior (from 15 to 20% from control group). Not only the distal anatomical localization of the muscle affects the conduction velocity, but also the proportion of muscle fiber type, where the tibialis anterior, with greater type I fiber proportion, is affected already at the absent group while the vastus lateralis with greater type II fiber proportion is affected in later stages of the disease. Generally, the muscles of the lower limb have different responsiveness to the effects of diabetes mellitus and neuropathy and show a reduction in the conduction velocity as the neuropathy progresses

Contextualization: The Diabetes Mellitus (DM) is an epidemic disease in the world and stay associated with right index of morbidity and mortality and about 90% of cases of DM are type 2 (DM2). DM2 develop by inflammatory mechanisms carrying the insulin resistance and consecutively blond hyperglycemia. Believes that in chronic stages the diabetes causes musculoskeletal dysfunctions can be related to inflammatory and metabolic alterations of the DM2 or with diabetic polyneuropathy. Some studies identified the musculoskeletal alteration in diabetic subjects. However not is clearly if the polyneuropathy cause muscle alteration proportionality sensitive alterations. Also weren’t observed studies that analyzed the torque in subjects with DM2, considering others factors that could influence the muscle torque production and also not were observed studies analyzing the torque in diabetic subjects during different types of contractions (concentric, eccentric and isometric). Objectives: The aim of the present study were analyze the torque at concentric eccentric and isometric muscle contractions in diabetic subject with and without polyneuropathy comparing with a control groups. Methods: The peak torques of flexion and extension were acquired using an isokinetic dynamometer, in sitting position. During concentric and eccentric contractions, the joint speed was set at 60°/s. Five maximal voluntary contractions were acquired for concentric and eccentric and 2 for isometric, with a rest interval of 1.5 minutes. The sequence of the tests was randomized and verbal and visual feedback were standardized and delivered to all subjects by the same person. Three groups of adult males were selected for this study (1) Control group (healthy non-diabetic patients, n=33), (2) Diabetic group (patients with diabetes mellitus without polyneuropathy, n=31), (3) Neuropathic group (patients with diabetic polyneuropathy, n=28). The Neuropathic group was defined according to a fuzzy model of signs and symptoms. Differences between groups were calculated with one way ANOVA for parametric knee variables (α of 5%) and Mann Whitney and Willcoxon for non-parametric ankle variables (adjusted α of 1.6%). To describe effect sizes, Hedges’ g was calculated. Results: Irrespective of polyneuropathy, both diabetic groups presented lower peak torques of knee and ankle, both for isometric contraction and for concentric flexion and extension. Other factors beside the polyneuropathy and early in the diabetes onset, may be influencing in the muscle strength production. The eccentric contraction was not different between any groups.
Contextualização: A Diabetes Mellitus (DM) se tornou uma doença epidêmica em todo mundo, e também está associada a altos índices de morbidade e mortalidade. Cerca de 90% dos casos são de DM do tipo 2, que desenvolve por meio de mecanismos inflamatórios que levam à resistência à insulina e consecutivamente à hiperglicemia sanguínea. Acredita-se que em estágios avançados a DM2 cause disfunções musculoesqueléticas, que podem estar relacionadas às alterações inflamatórias e metabólicas dessa doença ou à polineuropatia diabética (PND). Alguns estudos já identificaram alterações musculoesqueléticas em diabéticos. No entanto, ainda não está claro, se a polineuropatia acomete o sistema musculoesquelético, na mesma proporção que o sistema sensorial é acometido. Também não se observa na literatura, estudos que tenham analisado o torque de DM2, considerando outros fatores que podem influenciar a produção de torque e estudos que tenham analisado o torque nos três tipos de contrações (concêntrica, excêntrica e isométrica). Objetivo: O objetivo do presente estudo foi analisar o torque nas contrações concêntrica, excêntrica e isométrica em indivíduos com DM2, com e sem polineuropatia, comparados a um grupo controle sem DM. Métodos: Foram analisados três grupos de homens adultos (total 92), similares na distribuição de sexo, idade e características antropométricas: Controles não diabéticos (n=33); DM2 (n=31); PND (n=28). A PND foi avaliada por meio de um modelo Fuzzy. O pico de torque nas contrações concêntrica, excêntrica e isométrica foi avaliado com um dinamômetro isocinético de cadeira durante a flexão e extensão do joelho e dorsiflexão e flexão plantar do tornozelo. As diferenças entre os grupos foram calculadas com ANOVA one way, para as variáveis paramétricas de joelho (α of 5%) e Mann Whitney e Willcoxon para dados não paramétricos das variáveis do tornozelo (α ajustado de 1.6%). O tamanho de efeito foi calculado usando Hedges’ g. Resultados: Independente da polineuropatia, ambos os grupos diabéticos apresentaram menor torque concêntrico e isométrico de joelho e tornozelo, comparados aos Controles, mas sem diferença entre si. Para o torque excêntrico não houve diferença entre os três grupos em todos os movimentos e articulações avaliadas. Conclusão: A diminuição do torque concêntrico e isométrico em DM2 ocorre mesmo antes da instalação da PND, em tornozelo e joelho, enquanto o torque excêntrico permanece preservado nesses movimentos em diabéticos, independentemente da PND. Observa-se acometimento proximal e distal, com tamanhos de efeito maiores para os movimentos do joelho.

Full textMuscle force estimation could support a better understanding of the mechanical and muscular strategies that diabetic patients adopt to preserve walking ability and to guarantee their independence as they deal with their neural and muscular impairments due to diabetes and neuropathy. Our aim was to estimate and compare the lower limb\'s muscle force distribution during gait in diabetic patients with and without diabetic neuropathy. Data from ground reaction force (AMTI OR61000 force plate at 100Hz) and three-dimensional kinematics of ankle, knee and hip (eight-camera Optitrack® at 100 Hz) of 10 neuropathic (DNG), 10 diabetic non-neuropathic (DG) and 10 healthy individuals (CG) were used as input variables for the musculoskeletal model gait 2392 (23 degrees of freedom and 92 musculoskeletal actuators) in the OpenSim software. The standard generic model was scaled to fit the anthropometry of each individual collected, prior to the execution of the simulations. The musculoskeletal model of neuropathic individuals presented maximum isometric force reduced in 30% for ankle extensors and 20% for ankle dorsiflexors to mimic the atrophy of ankle muscles due to diabetic neuropathy. The force time series of lower limb muscles were calculated using the static optimization procedure. The peak muscle forces were calculated during selected time bands of the gait cycle. The peak force was compared between groups using MANOVA for the flexor and extensor muscle groups of hip, knee and ankle joints followed by ANOVA and post-hoc of Newman-Keuls (p < 0.05). DNG showed higher knee flexors peak force (biceps femoris short head / p < 0,001, semitendinous / p < 0,001 and semimenbranous / p < 0,001) during push-off, compared to DG and CG. DNG also presented lower peak force for gastrocnemius medialis and soleus, as well as higher peak force for gastrocnemius lateralis compared to DG and CG in the same gait phase. DG exhibited lower peak force for the hip extensor muscles (semitendinous and semimembranous) in the final swing and hip abductor muscles during stance, as well as higher peak force for the knee extensor muscles (vastus medialis and lateralis / p=0,004) in the early stance compared to DNG and CG. Diabetic patients with and without neuropathy appear to adopt different muscle force distribution strategies in spite of the progressive worsening in their health condition. While reducing ankle extensor forces, DG increased knee extensor muscle forces at early stance and reduced the hamstrings force at the end of swing phase, whereas DNG increased the hamstrings muscle forces at push-off. A resistance training program for the proximal muscles related to the knee joint could be considered in a rehabilitation routine for diabetic patients. Other potential inclusions in rehabilitation protocols consist of gait retraining and practicing functional exercises focusing on the activation of the hamstring muscles

Full textNeuropathy is a severe progressive loss of protective sensation on the feet, making the patient more vulnerable to mechanical trauma and consequently more suitable to the development of chronic wounds, major distortion of the foot bone architecture and eventually to limb amputation. Prophylaxis should be enforced to avoid foot ulceration and for that, evaluation of the degree of loss of sensation on the skin is essential. The PSSD (Pressure Specified Sensory Device(TM)) was developed in order to quantify the threshold of pressure applied to the skin that could be recognized as positive by the patient. Pressure of one or two points is tested both statically and with movement, thus assessing the function of fast and slow response nerve fibers. Threshold of two-point discrimination was also measured in mm. Thirty four (n = 34) diabetic patients, type II, with no previous history of wounds on the lower extremity were studied using the tests, one point static (1PE), one point moving (1PD) and two points static (2 PE), and moving (2 PD) on the cutaneous territory of the fibular nerve and posterior tibial nerve (two territories - medial plantar and calcaneous nerves). The control group (28 non diabetic patients) was assessed by the same exams and the results were compared. In the diabetic group the cutaneous territories were also evaluated using the conventional Semmes-Weinstein filament nº 5,07 e vibrometer of the 128 Hz. Altered values were observed for the static and dynamic tests over the three studied nerve territories. The differences were statically significant (p < 0,05). Comparing the threshold of sensibility between sensitive and non sensitive diabetic patients to MSW nº 5,07 test, we observed that p-value range was 0,018 0,113 when 1PE test was applied, and 0,002 0,083 when 2PE test was applied, according to the cutaneous territories evaluated. Numeric quantification of the threshold of pressure allows us to determine the status of the fiber/receptor structures as well as the functional deficit of nerve fibers. Our findings suggest that PSSD(TM) is an adjuvant tool to evaluate the degree of loss of sensation on the skin.
