Hip Abductor Function During Trendelenburg Test

Ahram Canadian University30 enrolled

Overview

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

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.

Outcomes

Primary Outcomes

Gluteus Medius Activation

Mean EMG activity of the gluteus medius during the Trendelenburg test at different hip positions. Measured bilaterally in microvolts (μV).

Time frame: Baseline

Secondary Outcomes

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.

Time frame: Baseline

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.

Time frame: Baseline
