This is a current study to see if strengthening the hip muscles while unload osteoarthritic knees. Duh. This is a good example of how the physical therapy profession is a bit behind due to its infatuation with evidence-based practice and desire for autonomy in health care. The good news is that it's drifting away from the isolationist's approach and somewhat expanding to a more integrated perspective. What typically starts as an investigation of the knee joints with studies of the quadriceps and hamstrings is now progressing to the hip's gluteals. Pretty soon studies will dare to step out of the box and look into improving intestinal peristalsis, bile flow, digestion, liver detoxification, and overall hydration of an individual to improve osteoarthritic cases.
