After a total hip replacement, what is the purpose of initiating functional electrical stimulation in a patient with Trendelenburg gait?

• A. Right abductors during swing on the right
• B. Right abductors during stance on the right
• C. Left abductors during stance on the right
• D. Left abductors during swing on the right

Answer: (B)

The initiation of functional electrical stimulation for a patient exhibiting Trendelenburg gait after a total hip replacement primarily focuses on addressing the strength and stability of the hip abductors during the stance phase of gait on the affected side. In cases of Trendelenburg gait, the patient's ability to adequately stabilize the pelvis while standing on one leg is compromised due to weakness in the hip abductor muscles (particularly the gluteus medius). When the affected leg is on the ground, there is a tendency for the pelvis to drop on the opposite side, resulting in the characteristic gait pattern. By providing stimulation to the right abductors during stance, the goal is to enhance the muscular support needed to maintain pelvic level and control during walking. This assistance helps facilitate a more normalized gait pattern, allowing for improved balance and overall function. The focus on the stance phase is critical, as this is when the patient requires the most support from the hip abductors to prevent pelvic drop and promote effective propulsion. This is why stimulating the right abductors during the stance phase on the right is the appropriate choice for addressing the deficits associated with Trendelenburg gait following surgery.
