Differentiated activation of hip abductors
Differentiated activity of the hip abductors has been noticed in a task-specific manner during hip exercises. The aim of this study was to compare the activity of the superficial and deep parts of the gluteus medius and the gluteus minimus in a selection of weight and non-weight bearing hip exercises.
M-mode ultrasound was used to capture activity-related muscle motion of the gluteus minimus and medius muscles in 20 healthy volunteers during weight shift, hip hitch, side-lying abduction and active leg lengthening exercises
The results of this study indicated a differentiated activity of the gluteus medius and minimus muscles only during weight bearing exercises. The activation of the deep and superficial regions of the gluteus medius showed an onset variability too. During non-weight bearing exercises a sychrnonous onset was observable.
