Stretch-sensitive afferent feedback from hip muscles has been shown to trigger long-lasting, multijoint reflex responses in people with chronic spinal cord injury (SCI). These reflexes could have important implications for control of leg movements during functional activities, such as walking. Because the control of leg movement relies on reflex regulation at all joints of the limb, we sought t...

Kinematic and kinetic changes in the lower extremities occur as an athlete becomes fatigued during vertical jumping; however, specifics of these are not well-understood. Therefore, purpose this study was to quantify influence a sport-specific, jumping fatigue protocol on biomechanics ankle, knee, hip joint. Twenty male varsity athletes performed repetitive standing countermovement squat jumps e...

The aim of the study was to investigate how kinematic and kinetic adjustments between level and slope locomotion of persons with transtibial amputation are related to their individual muscular and functional capacities. A quantified gait analysis was conducted on flat and slope surfaces for seven patients with transtibial amputation and a control group of eight subjects to obtain biomechanical ...

Purpose: It is essential to maintain dynamic stability during walking to perform daily tasks independently. The present study aimed at comparing the spatiotemporal parameters and the values of the vertical ground reaction force (vGRF) as well as determining the time to reach them in ankle-sprain coper and healthy athletes during the stance phase of gait. Methods: A total of 28 female universit...

INTRODUCTION Gradual training has been shown to be an effective method to introduce gait perturbations. Previous studies have shown that, when compared to a sudden introduction of asymmetrical walking on a treadmill, gradual training results in efficient motor learning and balance control, and decreased cognitive demand during retention [1]. The kinetic strategies needed to affect these outcome...

BACKGROUND Lateral ankle sprain (LAS) has often been considered an injury leading to localized joint impairments affecting the musculoskeletal system. Persistent chronic ankle instability and bilateral alterations in motor control after a first ankle sprain episode suggest that the origin of relapses might be a maladaptive reorganization of central motor commands. The objectives of this study w...
