BACKGROUND Due to biomechanical differences, various patterns of muscle contraction are expected to occur while walking over ground versus when walking on a treadmill. OBJECTIVES This study aimed to compare amplitude and duration of activation of selected trunk and lower extremity muscles during over-ground and treadmill walking. MATERIALS AND METHODS Through a simple sampling method, 19 se...

Under investigation is whether intramuscular (IM) electromyography can be used to trigger functional electrical stimulation (FES) to improve ambulation for the child with cerebral palsy (CP). In this study, bifilar percutaneous intramuscular (IM) recording electrodes were implanted bilaterally into a quadriceps muscle of a child with CP. Following implantation, 5 walking trials consisting of 2-...

The objective of this study is to compare the muscular activity of lower extremity muscles while running on treadmill and on overground surfaces. A total of 13 experienced heel-to-toe runners participated in the study. Electromyographic (EMG) data of four lower extremity muscles, including rectus femoris, tibialis anterior, biceps femoris, and gastrocnemius, were collected using the Noraxon EMG...

The muscles of 70 patients with lower limb shortening due to various etiologies were studied using three radiographic diagnostic methods: contrast radiography (CR), ultrasonography (US), and computed tomography (CT). The studies were performed before surgery, during lengthening using the Ilizarov external fixator, during the fixation period following distraction, and after apparatus removal. Th...
