What is an appropriate next step if a patient fails the Trendelenburg Test?

• A. Reassess knee stability
• B. Refer for imaging of the hip
• C. Conduct a strength test for hip abductors
• D. Instruct the patient in stretching exercises

Answer: (C)

When a patient fails the Trendelenburg Test, it indicates a potential weakness in the hip abductor muscles, particularly the gluteus medius. This test assesses the strength and function of these muscles, which play a critical role in stabilizing the pelvis during single-leg stance. If weakness is identified, conducting a strength test for hip abductors is a logical next step. This can help determine the severity of the weakness and guide further interventions or treatment plans.

By performing a strength test, the clinician can gather more specific information about the patient's muscular function and identify any deficits that may need to be addressed through rehabilitation exercises. This approach allows for targeted interventions to restore strength and stability in the hip region, which is essential for proper gait and overall mobility.

Other options, such as reassessing knee stability or referring for imaging of the hip, might be considered based on the patient's symptoms or findings during the assessment, but they do not directly address the specific weakness identified through the Trendelenburg Test. Stretching exercises may also be beneficial later on, but they would not be the immediate next step after failing this specific test.
