Clinical Trial Summary

This study will use electromyography and dynamometry to evaluate gluteal muscle activation during the Trendelenburg hip abduction test in different hip positions.

Description:

The Trendelenburg test is commonly used to assess hip abductor weakness. However, it is unclear which hip position during this test best isolates gluteal muscle function. This study will measure gluteus medius and minimus activation and hip abduction force in 30 healthy participants performing the Trendelenburg test. Different hip flexion, extension, adduction and abduction angles will be evaluated to determine which position optimally targets the gluteal muscles. Results may enhance utilization of the Trendelenburg test in clinical practice.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Gluteus Medius Activation	Mean EMG activity of the gluteus medius during the Trendelenburg test at different hip positions. Measured bilaterally in microvolts (µV).	Baseline
Secondary	Gluteus Minimus Activation during Trendelenburg Test	Mean muscle activation amplitude (measured in microvolts, µV) of the gluteus minimus during the Trendelenburg hip abduction test across a range of hip flexion, extension, adduction and abduction angles from 0 to 45 degrees. Measured bilaterally using surface electromyography electrodes placed on the muscle belly of the gluteus minimus.	Baseline
Secondary	Hip Abduction Strength during Trendelenburg Test	Maximum voluntary isometric hip abduction strength (measured in Newtons, N) during the Trendelenburg hip abduction test maneuver. Measured bilaterally at each combination of hip flexion, extension, adduction and abduction angles using a stabilized handheld dynamometer placed just proximal to the lateral femoral condyle.	Baseline
