Background: The purpose of this study was to investigate the ratio of Electromyography (EM G) activities of the vastus medialis obliqus (VMO) and vastus lateralis (VL) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (OK C) and closed kinetic chain (CKC). Methods: The dominant knees of 44 healthy female subjects (mean age: 24.84 with range...

Abstract Introduction Early post-operative dependency aids healing following lower limb reconstruction although increases venostasis and reduces perfusion in the acute setting. The commonest cause of flap failure is venous congestion external compression with stockings pneumatic devices contraindicated. aim this clinical study was to determine whether could be reduced through patient-led isomet...

[Purpose] This study compared the activity of trunk and hip muscles during different degrees of lumbar and hip extension. [Subjects] The study enrolled 18 participants. [Methods] Two exercises (hip and lumbar extension) and two ranges (180° and <180°) were studied. [Results] Differences in degree of extension affected the percentage maximal voluntary isometric contraction of the lumbar erector ...

The purpose of this training study was to determine the magnitude of strength gains following a high-intensity resistance training (i.e., improvement of neuromuscular coordination) that can be achieved by imagery of the respective muscle contraction imagined maximal isometric contraction (IMC training). Prior to the experimental intervention, subjects completed a 4-week standardized strength tr...

Study Design: Single-occasion, repeated-measures design. Objective: To determine the magnitude of hip abductor muscle activation during 6 rehabilitation exercises. Background: Many researchers have reported that hip strengthening, especially of the hip abductors, is an important component of a lower extremity rehabilitation program. Clinicians employ non–weight-bearing and weight-bearing exerci...

The aim of this study was to investigate the effects of two different frequencies of whole-body vibration (WBV) training on knee extensors muscle strength in healthy young volunteers. Twenty-two eligible healthy untrained young women aged 22-31 years were allocated randomly to the 30-Hz (n=11) and 50-Hz (n=11) groups. They participated in a supervised WBV training program that consisted of 24 s...
