Abstract:
Real-time ultrasound imaging (US) to measure abdominal muscle dimensions has aided low back pain rehabilitation and research. Notwithstanding, ultrasound imaging measurement of transversus abdominis muscle activation in chronic low back pain populations has been characterized by variable and generally suboptimal intra-observer reliability. Methodological deficiencies of ‘freehand’ ultrasound imaging are uncontrolled probe–skin pressure, inclination and roll of the probe. Despite previous attempts to standardize these parameters, intra-observer reliability in chronic low back pain was poor to m

Data were analysed using both descriptive statistics (count, percentage and mean) and inferential statistics (multiple regression and intra-class correlation). The results found the F-value of 2.7778 significant at P≤0.001implying that the model was reliable; and

Abstract:
Isometric strength testing using a digital dynamometer is reliable for muscle function evaluation. It allows us to objectify manual strength assessment measurement. We tested intra- and inter-observer reliability of a user-friendly efficient digital dynamometer—the Forcemeter—equipped with a computer program to monitor the measurements and to store the data. Abduction, forward flexion, and external and internal rotation of both shoulders were tested three times in 20 healthy volunteers with no record of shoulder trauma. Isometric contracture was recorded in newtons. The first and the third tes

We assessed the reproducibility and validity of a food frequency questionnaire (FFQ) among middle-aged and older adults in Semarang, Indonesia. A total of 259 subjects aged 40–80 years completed two FFQs (nine-month apart) and nine 24 h dietary recalls (24HDRs, as a reference method). The reproducibility of the FFQ was analyzed using correlation coefficient, intra-class correlation coefficient (ICC), weighted kappa statistics and misclassification analysis. The validity was estimated by comparing the data acquired from FFQ1 and 24HDRs. The crude Pearson’s correlation coefficients and ICC for t

Abstract:
Background and Objectives: Chronic functional constipation is a common condition that declines the quality of life (QoL). The constipation-related disability scale (CRDS) precisely measures the disability caused by constipation and its effect on daily activities. In this study, we translated the CRDS into Persian and evaluated its reliability and validity. Methods: We used the international QoL assessment procedure to translate the CRDS into Persian. The translation was then given to 145 patients (59 men and 86 women) with chronic functional constipation. Also, 130 healthy individuals complete

Abstract:
Arterial spin labeling (ASL) is a noninvasive method to measure cerebral blood flow (CBF). Arterial spin labeling is susceptible to artifact generated by head motion; this artifact is propagated through the subtraction procedure required to calculate CBF. We introduce a novel strategy for mitigating this artifact based on weighting tag/control volumes according to a noise estimate. We evaluated this strategy (DVARS weighting) in application to both pulsed ASL (PASL) and pseudo-continuous ASL (pCASL) in a cohort of normal adults (N = 57). Application of DVARS weighting significantly improved te
