introduction: knee orthosis is used in different cases and can be seen pistoning movement in all orthosis. the purpose of this study was to evaluate the effects of increasing mass knee brace and two kinds of silicon and polyethylene (pe) pad on pistoning movement during walking, on health subject. material and methods: a total of 20 healthy volunteers, including 10 men and 10 women, with an ave...
introduction: transtibial amputation is the most common amputation in lower limbs. volume loss of residual limb occurs during daily use of prostheses, which results in pistoning between residual limb and prosthetic socket. the goal of this study was to design and fabricate a pneumatic suspension system in transtibial supracondylar prostheses and to evaluate its effect on residual limb pistoning...
objectives: the purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (sis) and thirteen persons without it. methods: values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior tipp...
Background. Wrestling is one of the most popular sports in the world. United World Wrestling have developed “Wrestling+” injury prevention program similar to the FIFA 11+. Objectives. the aim of the present study was to investigate the effect of 12 weeks “Wrestling+” warm-up program on Functional Movement Screen scores in cadet wrestlers. Methods. The study population included all cadet wrest...
Purpose. The effects of practice were analyzed in the control of fast and accurate spatially constrained movements. Methods. Twenty men (20–26 years old) evenly divided into an experimental and control group were analyzed in three time periods: pre-test, post-test, and retention. Discrete Aiming Task ver. 2.0 software simulated Fitts’ task (1954) and provided kinematic analysis of mouse cursor ...
Purpose. The authors tried to point out the crucial factors determining swimming results in a 2000m front crawl race. Basic procedures. Two groups of subjects: G1 (16.8 ± 0.77 years) and G2 (14.7 ± 0.49 years) of 15 swimmers each took part in two incremental tests for assessing aerobic endurance of arms in arm cranking (V̇O 2max AR) and of legs in cycling (V̇O 2max LG). The applied procedure made...
Purpose. The aim of the study was to evaluate and compare the physical activity patterns of preschoolers aged 6–7 years. Methods. A sample of 221 preschool children (116 boys and 105 girls) aged 6 (5.92 ± 0.30) and 7 (6.91 ± 0.25) years was recruited. Physical activity was assessed over 7 consecutive days by using pedometers to determine step counts (steps/day). Accrued anthropometric data incl...
TAKE HOME MESSAGES 1. Movement disorders involve the basal ganglia and associated structures, often affecting the globus pallidus (the output target of the striatum) 2. Abnormal involuntary movements are classified as hypokinetic or hyperkinetic, and are subclassified byspeed, duration and whether or not they are rhythmic. 3. Parkinsonism is characterized by the presence of at least 2 of the 4 ...
alcium just got a promotion. Findings by Caroppo et al. (page 111) reveal that in addition to its many roles inside the cell, Ca 2 ϩ has a distinct extracellular purpose: it acts via a Ca 2 ϩ receptor (CaR) to regulate the function of gastric epithelial cells. It has been known for some time that extracellular Ca 2 ϩ can be sensed by the CaR. The team noted that a Ca 2 ϩ gradient was generated ...
