Hip Abductor Function During Trendelenburg Test

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.

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.

Inclusion Criteria:

• Healthy adults aged 18-45 years
• No history of hip disorders

Exclusion Criteria:

• Contraindications to EMG
• Neurological or muscular disorders
