Abstract:
Purpose. Uzbekistan aquaculture has a huge deficit of balanced feed. In a case of feed production from local ingredients, the problem is the lack of stable source of animal protein. The purpose of this experiment was to find out how swan mussel Anodonta used as a feed additive for African catfish will affect fish growth. Methodology. Minced Anodonta was prepared as follow: mussels were collected from the bottom of ponds after fish harvesting; the collected mussels were kept in the separate aquarium; every day several mussels were taken out, their shells were opened and muscle parts were separated the (mostly mussel leg); then the separated muscle were kept for disinfection in KMnO4 solution of low concentration during 20 min and then crushed to a minced state. Feed was given to African catfish according to a special scheme at the rate of 7% of the fish weight. The control group did not receive the minced mussels and fish were fed with carp feeds.The mixed feed in the experimental group #1 consisted of 50% carp feed and 50% minced mussel. In the experimental group #2, African catfish were fed with minced mussels only. Findings. The experiment showed the clear advantage of feed containing 50% of minced clams and 50% of carp feed. The African catfish fed with this feed significantly overtook fish from the control group in weight because this feed turned out to be either the most balanced in composition or better absorbed by catfish. In the control group, the 100% mixed feed gave an increase of 83.8% in weight and 20.5% in length; in the experimental group #1, the feed (50% mixed feed : 50% minced mussel) gave an increase of 136% in weight and 31.1% in length; at the experiment #2 (100% minced mussel), the feed gave an increase of 95.5% and 20.1% in length. Originality. For the first time the swan mussel was used as a source of animal protein for African catfish.This experiment was conducted for the first time, and it was also found for the first time that the addition of minced swan mussel to the feed of African catfish contributed to a significant weight gain compared to the conventional feed:52.5% more compared to conventional feed and 40.5% more compared to pure minced swan mussel. Practical value. Aquaculturenow is in search of source of animal proteinin connection with growing global deficit of a high quality fishmeal for fish feed production. Use of bivalve mollusks Anodonta, which are also a pest in pond farms, is promising feed for obtaining physiologically determined weight gains. Key words: aquaculture, Africaт catfish (Clarias gariepinus (Burchell, 1822)), feed, animal protein, plant protein, water quality, swan mussel (Anodonta cygnea (Linne, 1758)), weight gain.

Abstract:
Aim. Although more than 80 fi sh species and some invertebrate aquatic organisms are known to be susceptible to in- fectious pancreatic necrosis virus (IPNV) and aquatic birnaviruses, relatively little is known about its ability to infect brown trout (Salmo trutta), zebrafi sh (Danio rerio), and a mollusk, swan mussel (Anodonta cygnea). Therefore, the aim was to study in more detail the effects of IPNV on the said organisms. The information on the virulence of birnaviruses for aquatic organisms is important for better understanding of their transmission and for the identifi cation of suscep- tible or transient (symptomless) hosts. Methods. Cell culture method, using RTG-2 cells, was used for in vitro culti- vation of IPNV as well as virus titer assessment. The supernatants from infected RTG-2 cells were used for artifi cial inoculation to obtain experimental infection of the fi sh and mollusk. Fish and mollusk behaviour and mortality were monitored daily. The infectious titer of the virus in experimental animals was assessed by cell culture assay and reverse transcription PCR (RT-PCR). Results. This paper presents the results of IPNV experimental infection of brown trout (Salmo trutta), zebrafi sh (Danio rerio), and an aquatic invertebrate mollusk - swan mussel (Anodonta cygnea). The mortality of brown trout and zebrafi sh was 76.6 and 40 % respectively. Swan mussel was apparently resistant to the virus, but it apparently accumulated and maintained substantial levels (up to 10 -10 ID 50 /ml -1 ) of the virus for the dura- tion of the experiment (35 days). The highest infectious titer was found in brown trout (10 6 ID 50 /ml -1 ). In zebrafi sh and swan mussels, it was up to 10 4.5 ID 50 /ml -1 and 10 2 ID 50 /ml -1 respectively. Conclusions. At the end of the experiments the IPNV titers were higher than the initial viral doses in brown trout and zebrafi sh, indicating virus reproduction. In diseasesd fi sh the blackening, whirling and anorexia were observed. It was shown that swan mussel accumulates and maintains virus for at least 35 days under experimental conditions and that it may act as symptomless vector of IPNV

Abstract:
Haemocytes play a major role in molluscs immunity. Functional studies are, however, impaired by limited available experimental tools to identify and sort distinct haemocyte populations. Therefore, using nonlethal methods, we aimed at evaluating whether lectin staining combined with flow cytometry could be used to distinguish circulating haemocyte populations from two freshwater bivalves of the family Unionidae, the duck mussel (Anodonta anatina (L., 1758)) and the swan mussel (Anodonta cygnea (L., 1758)). Based on classical classification, haemocytes were distinguished as granulocytes and hyalinocytes and cytological features were visualized using transmission microscopy and staining techniques. Size, granularity, viability, and surface staining using lectins as specific probes were analysed by flow cytometry and fluorescence microscopy. The microscopic proportions of granulocytes and hyalinocytes significantly differed, being of 70% and 30% for A. cygnea and of 85% and 15% for A. anatina, respectively. Two haemocyte populations were sorted by flow cytometry based on size and granularity and confirmed as granulocytes and hyalinocytes. Interestingly, two different granulocyte populations could be further discriminated in A. cygnea according to their binding affinity to wheat-germ agglutinin (WGA), whereas granulocytes of A. anatina all stained similarly. Our results show that WGA labelling combined with flow cytometry can be used to better discriminate Anodonta haemocyte populations and obtain purified populations for functional studies.

Abstract:
Freshwater mussels are one of the most imperiled faunistic groups in the world and environmental exposure to toxic heavy metals, which result in deregulation of calcium absorption and deposition in the laboratory, may be a contributing factor in their decline. To address potential effects of heavy-metal exposure on calcium transport and metabolism in freshwater bivalves, adult Anodonta cygnea (L., 1758) were exposed to a sublethal concentration (1.0 × 10−6 mol/L) of essential (Zn2+ and Cu2+) or nonessential (Pb2+ and Cr3+) metal for 30 days in the laboratory. Inorganic composition of extrapallial, haemolymph, heart, and pericardium fluids, and kidney tissue, as well as shell morphology by scanning electron microscopy, were compared in treated and untreated mussels. Calcium levels in fluids varied after exposure to any of the metals investigated, although the magnitude and threshold of effect were metal- and compartment-specific. Ca2+ levels increased robustly in all fluids following exposure to Zn2+, Cu2+, or Cr3+, whereas levels decreased significantly in heart fluid alone following Pb2+ exposure (p < 0.05). In constrast to exposure to the other metals, Cu2+ revealed an interesting reverse-accumulation pattern, decreasing in the fluids but not in the kidney, where it clearly accumulates for excretion. In addition, whereas essential Cu2+ and Zn2+ are closely regulated, the nonessential metals Pb2+ and Cr3+ increase to very high levels. Drastic alterations in shell morphology, specifically the structure of border and inner pallial regions of the nacreous layer, were observed after Cu2+ or Cr3+ exposure. Collectively, data suggest that prolonged exposure to a sublethal concentration of these heavy metals can adversely affect compartmental calcium availability and shell composition in A. cygnea.

Abstract:
Special Weapons and Tactics (SWAT) officers constitute a subgroup of specialized law enforcement officers that perform a variety of tactical operations while wearing approximately 40 kg of tactical gear. Lower back pain is a prevalent musculoskeletal injury suffered by SWAT officers. Tactical gear places significant stress on the lower back. Thus, it is important to quantify the effect that tactical gear has on muscle activation levels of torso musculature while performing occupational tasks. Electromyography was evaluated on 20 male subjects (age: 34.7±4.5 yr.; height: 1.79±.10 m; body mass: 91.53±17.32 kg; mass of gear: 13.82±1.90 kg) while performing four tactical tasks (standing, rifle walk, sitting, & shield walk) with and without gear. Electromyography was evaluated bilaterally on the erector spinae, rectus abdominis, and external oblique muscles. The dominant erector spinae (mean delta: +0.16%) and external oblique (mean delta: -0.124%) demonstrated significant changes in muscle activation with the addition of gear, which may indicate increased spinal compression. There were also trends of increased co-activation of core musculature with the addition of gear. The rifle walk and shield walk task mean muscle activations were significantly higher than the standing and sitting tasks. The shield walk produced the highest mean activations for each muscle. Physical training for SWAT officers should emphasize exercises that simulate task-specific movement patterns without gear to decrease the spinal compression associated with load carriage.

Abstract:
The purpose of this study was to quantify muscle activation and body sway on a series of unstable surfaces. Surface electrodes were used to obtain muscle activation data from the tibialis anterior, gastrocnemius, gluteus medius, and gluteus maximus while body sway data (mean amplitude of A-P Sway, mean amplitude of M-L Sway, and Sway Index) was obtained using a force platform. Theraband stability trainers were used to provide a series of unstable surfaces. A total of fifteen participants (five females, ten males) volunteered in this study. It was determined that muscle activation increased as surfaces increased in instability. For example, peak tibialis anterior muscle activation when standing on the platform (one leg) was 34.5 %MVC while that for standing on the black surface was 64.9 %MVC. It was also determined that as body sway increased, muscle activation of the lower body increased as well. Several standing conditions (i.e. standing on one leg versus two legs, leaning in a particular direction) were also studied and it was determined that certain conditions significantly affect muscle activation as well as postural sway. This study provides objective muscle activity and postural sway data previously void in the literature which can be applied to a rehabilitation, health, or ergonomic setting.

Abstract:
This thesis investigated whether different textured surfaces have a role to play in changing balance performance in healthy young and older adults. A review of the literature showed that balance may be improved by standing on surfaces, or wearing foot insoles, with texture compared to those that are smooth, possibly by providing enhanced plantar tactile stimulation. It also showed that textured footwear interventions can influence lower limb muscle activity during functional activities. However, some major gaps in current literature were identified. There was limited evidence relating to the effect of texture in older adults: a population known to show poor balance and at high risk of falling. The importance of the geometric textured pattern in changing balance had not been investigated. It was also unclear whether textured interventions altered lower limb muscle activity, as a component of sensorimotor function of balance control. The purpose of this thesis was to address these important areas of research and contribute novel evidence to the field. In two separate studies, 24 young and 50 older healthy adults conducted tests of bilateral quiet standing with eyes open and closed on two different textured surfaces and a smooth surface as control. Centre of pressure based sway variables were extracted from a force platform and lower limb muscle activity was collected using surface electromyography, over 30 seconds. Textured surfaces did not significantly alter sway variables or lower limb muscle activity in healthy young adults. Closer observation of the data tentatively suggested texture may have the capacity to alter anterior-posterior sway and centre of pressure velocity in young adults. These findings supported the aims of this thesis to explore the possibility of a textured effect in people with poor balance ability: older adults. Textured surfaces significantly changed mediolateral sway range and centre of pressure velocity in healthy older adults, in the absence of visual information. No significant changes were observed for lower limb muscle activity, between the textured conditions. Exploratory sub-group analysis for gender generated speculative data suggesting the effect of texture on balance and muscle activity may be more marked in older females. Evidence from both studies suggests that relative to control, the two textured conditions have opposite effects on postural sway. There may be an optimal textured pattern which could be therapeutically beneficial for enhancing balance performance in healthy and pathological groups. Further investigation is required.

Abstract:
Application of pressure in the form of taping and bracing has been shown to improve proprioception, and inducing localized muscle fatigue at various musculatures has been shown to adversely affect postural control. However, the potential for pressure application to mitigate the effects of localized muscle fatigue on postural control has not yet been determined. This study investigated specifically the effects of circumferential ankle pressure (CAP) and induced ankle fatigue on postural control. Fourteen young participants (seven males and seven females) performed fatiguing sub-maximal isotonic plantar flexion exercises on an isokinetic dynamometer, in the absence and presence of a pressure cuff (60 mm Hg) used to apply CAP. Proprioceptive acuity (PA) was determined using a passive-active joint position sense test, with categorical scores (low or high PA) used as a covariate. Postural sway during quiet standing was assessed using a force platform both pre- and post-fatigue as well as in the absence and presence of CAP. Application of CAP resulted in larger postural sway in individuals with low PA, and reduced postural sway in individuals with high PA. Fatigue effects on postural sway in individuals with low PA were more substantial as compared to individuals with high PA. CAP was found to be ineffective in mitigating the effects of fatigue on postural sway in individuals with lower PA. As a whole, the results suggest a potential for CAP as an ergonomic intervention in controlling fatigue-related fall incidents, though conclusive recommendations for use are not justified.

Abstract:
Bakgrund: Nacksmärta är ett vanligt förekommande besvär och en av de främsta orsakerna till att söka vård hos fysioterapeut. Nackbesvär kan leda till förändringar i proprioception, både medveten och omedveten, vilket kan leda till en nedsatt balans. Undersökning av omedveten proprioception har gjorts genom att mäta posturalt svaj vid stimulering av muskelspolar via lokala muskelvibratorer i tidigare studier. Ingen studie har dock undersökt reliabiliteten vid stimulering av nack- och vadmuskler hos personer med respektive utan nacksmärta   Syfte: Studiens syfte var att utvärdera inter-day reliabilitet för posturalt svaj hos personer med eller utan nacksmärta genom att mäta CoP på WBB där deltagarna ges vibrationer på vader, nacke respektive underarmar.   Metod: 50 deltagare deltog i studien, 25 deltagare med nacksmärta och 25 friska kontroller. Deltagarnas CoP mättes på en WBB där deltagarnas förändring av CoP mättes innan, under och efter att vibrationer getts på vader, underarmar respektive nacken. Deltagarna testades vid två tillfällen med 7 dagars mellanrum. ICC2,1 användes för att beräknade relativ reliabilitet. Ett ICC-värde ≥ 0,75 bedöms som god reliabilitet. Absolut reliabilitet beräknades med SEM. Beroende t-test utfördes för att undersöka eventuell systematisk bias såsom adaptioner eller inlärningseffekter mellan testtillfälle 1och 2.   Resultat: Studiens resultat uppvisade en måttlig till utmärkt relativ reliabilitet (ICC = 0,69 - 0,89) för A/P amplituden för hela gruppen och SEM-värden var mellan 0,51 - 1,17 vilket utgör ca 20 - 30% av medelvärdet för de flesta svajvariablerna. En signifikant inlärningseffekt kunde ses för både A/P och M/L amplituden vid vibration av vadmuskulaturen (p = 0,015 - 0,017).   Slutsats: Studiens resultat visar på en acceptabel reliabilitet och testmetoden kan användas i såväl forskning som klinisk användning vid undersökning av posturalt svaj med eller utan vibration.
Background: Neck pain is a common occurrence and one of the main reasons for seeking care at a physiotherapist. Neck disorders can lead to changes in proprioception, both conscious and unconscious, which can lead to a reduced balance. Investigation of unconscious proprioception has been done by measuring postural sway in the stimulation of muscle spindles via local muscle vibrators in previous studies. However, no study has investigated the reliability of stimulation of neck and calf muscles in people with or without neck pain   Purpose: The purpose of the study was to evaluate inter-day reliability on postural sway in people with or without neck pain by measuring CoP on WBB where participants receive vibration on the calf, neck and forearms.   Method: 50 participants participated in the study, 25 participants with neck pain and 25 healthy controls. Participants change of CoP was measured before, during and after vibration was given to calf, forearm and neck. Participants were tested on two occasions at 7-day intervals. ICC2,1 was used to calculate relative reliability. An ICC value ≥ 0.75 is considered to be good reliability. Absolute reliability was calculated with SEM. Dependent t-test was performed to investigate any systematic bias such as adaptations or learning effects between test 1 and 2.   Results: The results of the study showed a moderate to excellent relative reliability (ICC = 0.69 - 0.89) for the A/P amplitude and SEM values ​​were between 0.51 - 1.17 which represents about 20-30% of the mean for most sway variables. A significant learning effect could be seen for both the A/P and M/L amplitude in vibration of the calf muscles (p = 0.015-0.017).   Conclusion: The results of the study demonstrate acceptable reliability and the test method can be used in research and clinical to investigate postural sway with or without vibration.

Abstract:
Context: It has been suggested that muscle fatigue can lead to injury, however, research investigating this phenomenon in functional ankle instability (FAI) subjects is lacking. Aim: The purpose of this thesis was to research postural sway and muscular latency in FAI subjects and healthy controls, both before and immediately after localised and globalised fatigue protocols. Subjects: All subjects used in this project were males, between the ages of 18 and 25 years, and participated in regular (>2 x week) aerobic exercise. Subjects were categorised into healthy subjects, or subjects with a history of FAI using the FAI questionnaire. Methods: Neuromuscular control was analysed in FAI subjects and healthy controls through measures of muscular latency and postural sway. These measures were repeated both before and immediately after localised and globalised fatigue protocols. Results: The induction of localised and globalised fatigue had no effect on muscle latency in the FAI or healthy subjects. However, postural sway was significantly increased in the FAI subjects, following localised and globalised fatigue, with globalised fatigue also significantly increasing postural sway in the healthy subjects. The globalised football-specific fatigue protocol caused the greatest deficits in the FAI subjects, but also the healthy controls. Conclusions: In terms of muscle latency individuals that participate in sports, as well as sports clinicians and coaches, should not be concerned about the theorised relationship between the onset of fatigue and an increased injury risk at the ankle. However, in terms of postural sway the globalised football-specific fatigue protocol caused the greatest deficits. This highlights that the fatigued individual may be at greater risk of musculoskeletal injury during prolonged exercise that involves multiple joints, such as a football match.

Objetivos: Avaliar os efeitos de 6 meses de suplementação com colecalciferol e cálcio sobre o metabolismo mineral e sobre os parâmetros de força muscular de membros inferiores, oscilação postural e mobilidade funcional. Desenho do Estudo: Ensaio clínico prospectivo, randomizado, duplo-cego, placebocontrolado. Local de realização: Duas instituições de longa permanência para idosos, em São Paulo - SP, Brasil. Participantes: 56 idosos de ambos os sexos (12 homens e 44 mulheres), com 60 anos de idade ou mais (mediana=77,6; limites=62-94 anos). Métodos: Os pacientes foram randomizados em Grupo-Ca (n=28) para placebo, ou Grupo-Ca+D (n=28) para colecalciferol. Todos os participantes receberam 1000 mg/dia de cálcio. O Grupo-Ca+D recebeu colecalciferol oral nas doses de 150.000 UI/ mês durante os 2 primeiros meses de estudo e 90.000 UI/mês nos 4 meses subseqüentes, correspondendo a uma dose mensal de 3670 UI/dia em média, de Dezembro-2004 a Maio-2005. Níveis séricos de 25-Hidroxivitamina D (25OHD), paratormônio intacto (PTH) e cálcio foram mensurados no início do estudo (M1), 2 meses (M2) e 6 meses (M3) após tratamento. Os testes neuromusculares foram realizados antes do início da intervenção e repetidos após o fim do tratamento. A força muscular dos membros inferiores foi avaliada através de um índice de força muscular (IFM), incluindo a força dos músculos flexores do quadril e extensores do joelho, mensurada por dinamômetro mecânico portátil. Para avaliar a oscilação postural foi criado um índice (IOP) a partir da mensuração da oscilação do corpo nos diâmetros sagital e frontal ao nível da cintura. A mobilidade funcional foi mensurada através dos testes “Timed Up&Go” (TUG) e alcance funcional (TAF). Resultados: A 25OHD sérica aumentou em ambos os grupos no M2, porém mais no Grupo-Ca+D do que no Grupo-Ca (OR=2,2; 95%IC=1,98-2,4 vs. OR=1,76; 95%IC=1.55-1.99, respectivamente). No M3, os níveis de 25OHD declinaram apenas no Grupo-Ca, contudo, o PTH sérico diminuiu no M2 (p<0.0001) e retornou aos valores basais no M3 (p<0.0001) igualmente nos dois grupos. Antes do tratamento, deficiência/insuficiência de 25OHD (<50 nmol/L) afetava 67,9% do total de participantes. No M3, nenhum paciente do Grupo-Ca+D, mas 40% dos pacientes do Grupo-Ca tinham deficiência/insuficiência de 25OHD. Hipercalcemia não foi detectada em nenhum paciente. Apenas no Grupo-Ca+D, o IFM teve um aumento de 20% no M3 (OR=1,20; 95%IC=1,12-1,29), enquanto que IOP e TAF aumentaram igualmente nos dois grupos, provavelmente porque os pacientes de ambos os grupos aumentaram sua exposição solar durante o verão. Conclusões: A suplementação com colecalciferol e cálcio foi segura e efetiva em aumentar os níveis séricos de 25OHD, reduzir a prevalência de deficiência/insuficiência de 25OHD e aumentar a força muscular de membros inferiores nos idosos do grupo tratado.

Objectives: To assess the effects of a 6-month supplementation with vitamin D and calcium on mineral metabolism and parameters of lower-extremity muscle-strength, body sway (BS) and functional mobility, measured by the Functional Reach Test (FRT) and Timed Up&Go test (TUG). Design: Prospective, double-blind, placebo-controlled trial. Setting: Institutionalized elderly of two long-stay geriatric care units of São Paulo-SP, Brazil. Participants: 56 elderly volunteers of both genders (12 men and 44 women) of ages 60 and older (median=77.6; range=62-94 years). Methods: Subjects were randomized into a Ca-group (n=28) to receive placebo or a Ca+D-group (n=28) to receive cholecalciferol. All participants received 1,000 mg/day of calcium. Laboratory measurements were performed at baseline (M1), 2 moths (M2) and 6 months (M3) after intervention. The Ca+D-group received oral cholecalciferol on a monthly basis (3670 IU/day on average, from December-2004 to May-2005). Neuromuscular measurements were performed at baseline and 6 months. Results: Serum 25(OH)D increased in both groups at M2, but more so in the Ca+Dgroup than in the Ca-group (OR=2.2, 95%CI=1.98-2.4 vs. OR=1.76, 95%CI=1.55- 1.99, respectively). At M3, 25(OH)D levels declined only in the Ca-group. Nevertheless, serum PTH diminished at M2 (p<0.0001) and went back to baseline levels at M3 (p<0.0001) equally in both groups. Before treatment, 25(OH)D deficiency/insufficiency (<50 nmol/liter) affected 67.9% of the entire group. At M3, no patient in the Ca+D-group, but 40% of the Ca-group patients had 25(OH)D deficiency/insufficiency. Hypercalcemia was not detected at any time. The odds of improving lower-extremity muscle strength increased by 20% (OR=1.20, 95%CI=1.12-1.29) only in the Ca+D-group, whereas BS and FRT increased equally in both groups, probably because the study was conducted during the summer. Conclusions: The supplementation with calcium and supra-physiological doses of cholecalciferol was safe and effective in enhancing 25(OH)D levels, reducing the prevalence of 25(OH)D insufficiency, and increasing lower-extremity muscle strength in institutionalized elderly.

Abstract:
At this point the chapters catch up in time with the events narrated in the prologue. Chapter 5 begins by recounting George Nicholls’ discoveries in June 1921. The detective searched the Goodings’ and Swans’ houses and took from the Swans’ a quantity of blotting paper that bore the imprint of some of the libels. Rose Gooding’s handwriting was very different. When Sir Archibald Bodkin, the Director of Public Prosecutions, read Nicholls’ report, he declared that this was fundamentally ‘a case of handwriting’. How, Bodkin mused, could an ‘uneducated’ woman develop such a distinctive style? The chapter uses Bodkin’s reaction to Rose Gooding’s letters, the evidence provided by spelling and misspelling, and the inventory of writing paraphernalia in the Gooding and Swan households, to explore the relationship between popular literacy and agency, engaging with the recent work of Jane Caplan and Patrick Joyce.

Abstract:
Prospective, concurrent-cohort study. To establish the relationship between radiographic alignment parameters and functional CoE measurements at one week before and at three months after realignment surgery in ADS patients. Adult degenerative scoliosis (ADS) represents a significant healthcare burden with exceedingly high and increasing prevalence, particularly among the elderly. Radiographic alignment measures and patient-reported outcomes currently serve as the standard means to assess spinal alignment, deformity, and stability. Neurological examinations have served as qualitative measures for indicating muscle strength, motor deficits, and gait abnormalities. Three-Dimensional motion analysis is increasingly being used to identify and measure gait and balance instability. Recently, techniques have been established to quantify balance characteristics described by Dubousset as the “cone of economy” (CoE). The relationship between radiographic alignment parameters and CoE balance measures of ADS patients before and after realignment surgery is currently unknown. 29 ADS patients treated with realignment surgery. Patients were evaluated at one week before realignment surgery and at their three-month follow-up examination. During each evaluation, patients completed self-reported outcomes (visual analog scales for pain, Oswestry Disability Index, SRS22r) and a functional balance test. Mean changes in dependent measures from before to after surgery were compared using paired t-tests. Pearson correlations were used to test for significant correlations between changes in radiographic and CoE measures. Significant improvements were found for all patient-reported outcomes, in several radiographic measures, and in CoE measures. Improvements of scoliosis Cobb angle, coronal pelvic tilt, lumbar lordosis, and thoracic kyphosis showed significant correlations with CoE sway and total distance measures at both the center of mass and center of the head. Improved radiographic alignment measures significantly correlated with improved CoE balance measures among ADS patients treated with realignment surgery at their three-month follow-up. These findings indicate that functional balance evaluations when used in conjunction with radiographic measurements, may provide a more robust and improved patient-specific sensitivity for postoperative assessments. CoE balance may represent a new measure of added value for surgical intervention of ADS.

Abstract:
Age-related increases in postural sway during quiet standing are well-documented [1]. These increases could result from age-related degradation of sensory information from the somatosensory [2] and vestibular [3] systems, or may result from inaccurate or imprecise muscle forces resulting from excitation-contraction uncoupling [4].

Abstract:
The cownose ray (Rhinoptera bonasus) demonstrates excellent swimming capabilities; generating highly efficient thrust via flapping of dorsally flattened pectoral fins. In this paper, we present a bio-inspired and free swimming robot that mimics the swimming behavior of the cownose ray. The robot has two artificial pectoral fins to generate thrust through a twisted flapping motion. Each artificial pectoral fin consists of one ionic polymer-metal composite (IPMC) as artificial muscle in the leading edge and a passive PDMS membrane in the trailing edge. By applying voltage signal to the IPMC, the passive PDMS membrane follows the bending of IPMC with a phase delay, which leads to a twist angle on the fin. The characterization results have shown that the pectoral fin was able to generate up to 40% tip deflection and 10° twist angle with less than 1 Watt power consumption. A bio-inspired rigid body was designed using Computerized Axial Tomography (CT Scan) data of the cownose ray body and printed using a 3-dimensional printer. A light and compact on-board control unit with a lithium ion polymer battery has been developed for the free swimming robot. Experimental results have shown that the robot swam at 0.034 BL/S.
