Physical Therapy Scholarly Projects
Purpose: The purpose of this study was to determine if an isometric hip adduction contraction and varied foot positions during a wall squat results in increased muscle recruitment of the lower extremity.
Subjects: Eleven healthy female adult volunteers without a prior history of knee pathology participated.
Methods: Surface electromyography (EMG) data were collected from the adductor longus (AL), vastus medialis oblique (VMO), vastus lateralis (VL), biceps femoris (BF), gastrocnemius (GN) and anterior tibialis (AT) muscles of the dominant leg for each individual during six wall squats with different treatment conditions. Experimental trials included three different rotation positions with or without …

Electromyographic Analysis Of Abdominal And Low Back Musculature During Use Of An Experimental Stationary Bicycle, Bryce A. Kelly, Christopher L. Podoll, Kirk R. Van Slyke
Physical Therapy Scholarly Projects
Background and Purpose. Currently, stationary bicycles do not incorporate exercise for the abdominal and low back musculature. An experimental stationary bicycle, the Magnus Cycle, has been developed to increase trunk muscle activation and, at the same time, provide aerobic conditioning. The purpose of this study is to assess the activity of the rectus abdominus, external oblique, erector spinae, rectus femoris and biceps femoris muscles during a stationary cycling setting and during a tilt-in-space setting of the Magnus Cycle.
Subjects. Sixteen subjects, both men and women, between the ages of 18 and 30 participated in this study.
Methods. Surface electromyography (EMG) …
