Hip Abductor Function During Trendelenburg Test

July 21, 2023 updated by: Mohamed Magdy ElMeligie, Ahram Canadian University

Electromyographic Evaluation of Hip Abductors During the Trendelenburg Test

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

Detailed 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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Healthy Adults
At least 30 healthy adult participants aged 18-45 years performing the Trendelenburg hip abduction test
Diagnostic test: Trendelenburg hip abduction test
The Trendelenburg test performed at different hip flexion, extension, adduction and abduction angles.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Gluteus Medius Activation
Time Frame: Baseline
Mean EMG activity of the gluteus medius during the Trendelenburg test at different hip positions. Measured bilaterally in microvolts (μV).
Baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Gluteus Minimus Activation during Trendelenburg Test
Time Frame: Baseline
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
Hip Abduction Strength during Trendelenburg Test
Time Frame: Baseline
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
