To date, most studies use surface electromyographic (sEMG) signals as the control source on active rehabilitation robots, and unilateral data are collected based on the gait symmetry hypothesis, which has caused much controversy. The purpose of this study is to quantitatively evaluate the sEMG activity asymmetry of bilateral muscles in lower extremities during functional tasks. Nine participant...

Purpose: Despite the widespread use of cryotherapy in sports, there is no specific evidence its impact on muscle activation, especially following fatigue-induced exercises. This study aimed to assess alone and after plyometric exercises knee activation during drop jump task. Methods: A total 35 active female subjects (mean±SD age 22.74±2.10 years, mean body mass index [BMI] 20.02±2.55 kg/m2) pa...

a do Rationale and Objective: Because lower limb muscles differ in architecture and function, the systemic effects of chronic obstructive pulmonary disease (COPD) and related disuse may result in regional abnormalities. The purpose of this study was to investigate the differences between patients with COPD and healthy controls in three-dimensional shape and size measurements of individual thigh...

During fatiguing upper limb exercise, maintained firing of group III/IV muscle afferents can limit voluntary drive to muscles within the same limb. It is not known if this effect occurs in the lower limb. We investigated the effects of group III/IV muscle afferent firing from fatigued ipsilateral and contralateral extensor muscles and ipsilateral flexor muscles of the knee on voluntary activati...
