[Purpose] The purpose of this study was to examine correlations between measurement time and different expansibility of the elastic tape on the rectus femoris and body sway index with plyometric exercise. [Subjects and Methods] The subjects of this study were 24 healthy men. C90 area, C90 angle, trace length, sway average velocity for body sway index were measured using a force plate by BT4. Th...

The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the electromyographic root mean square of Tr...

1) Background: The aim of this study is to present the results experiments in which surface electromyography (sEMG) and thermal imaging were used assess muscle activation during gait verify hypothesis that there a relationship case low fatigue level between sEMG-measured activation, assessed frequency domain, factors calculated as minimum, maximum, kurtosis, mean, median, mode from area interes...

INTRODUCTION Myositis ossificans (MO), heterotopic ossification, occurs in muscles and soft tissue. This lesion contains actively proliferating fibroblasts and osteoblasts. It commonly affects vigorous young men and more so among athletes. It occurs as a result of trauma, either acute or chronic and can also arise near joints in neurological disorders. By time of presentation, ossification is e...

OBJECTIVE This study is a statistical analysis to establish whether a correlation exists between the level and degree of rectus femoris (RF) central tendon injury and the amount of time that an athlete is unable to participate subsequently, referred to as "sports participation absence" (SPA). DESIGN Causal-comparative study. PATIENTS 35 players from two high-level Spanish soccer teams with ...

PURPOSE OF THE STUDY Cerebral palsy is a serious world-wide problem; its incidence ranges from one to five per thousand of live-born children and is much influenced by gestation age and birth weight. In orthopaedic treatment of lower extremity motor disorders, one of the options for contracture or deformity elimination and for stiff leg gait improvement is rectus femoris tendon transfer. The ai...
