Coordination Of The Lower Extremity Muscles During Gait Transitions, Lorna Louise Ogden Jan 2002

Coordination Of The Lower Extremity Muscles During Gait Transitions, Lorna Louise Ogden

LSU Master's Theses

Often the approach to investigating muscular coordination during transitions entailed conducting tests at speeds held constant. This study investigated muscular activity during continuously changing speeds in order to further detail and quantify neuromuscular changes during gait transitions. Twelve healthy adults, 18-41 years of age, were recruited as participants. Informed consent was obtained. Gait transitions were induced by the speed of the treadmill changing with constant acceleration. Reflective markers were placed on anatomical landmarks of the hip, knee,ankle, heel, and 5 th metatarsal joint. Bipolar surface electrodes were positioned on the subjects’skin over the muscular bellies of the gluteus ...
