简要总结
This study will use electromyography to evaluate activation patterns of the vastus medialis and vastus lateralis muscles during the McMurray's knee examination test in different knee positions.
详细描述
The McMurray test is commonly used to assess knee pathology. However, it is unclear which knee position during this test best isolates activity of the vastus medialis muscle. This study will measure vastus medialis and lateralis activation using surface electromyography in 30 healthy participants performing the McMurray test. Different knee flexion and rotation angles will be evaluated to determine which position optimally activates the vastus medialis. Results may enhance utilization of the McMurray test in rehabilitation programs targeting this muscle.
