Study Details

Study Description

Brief Summary

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.

Condition or Disease	Intervention/Treatment	Phase
Electromyography; Knee Injuries; Knee Pain Chronic	Diagnostic Test: McMurray knee examination test

Detailed Description

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.

Outcome Measures

Primary Outcome Measures

1. Vastus Medialis Activation [Baseline]

   Mean EMG activity of the vastus medialis during McMurray test at different knee positions. Measured in microvolts (μV).

Secondary Outcome Measures

1. Vastus lateralis EMG activity during McMurray test (μV) [baseline]

   Mean EMG activity of the vastus lateralis muscle during the McMurray knee examination test at different knee flexion and rotation angles. Measured in microvolts (μV).

2. Force exerted during McMurray test measured by dynamometer (Newtons) [baseline]

   Maximum voluntary isometric knee extension force measured using a handheld dynamometer during the McMurray knee examination test at different knee positions. Measured in Newtons (N).
