The Single Leg Squat Test assesses stability and neuromuscular control of which joints?

• A. Shoulder, elbow, and wrist.
• B. Hip, knee, and ankle.
• C. Lumbar spine and pelvis.
• D. Knee only.

Answer: (B)

During a single-leg squat, the body relies on the coordinated stability of the hip, knee, and ankle as a functional chain. The hip must stabilize the pelvis and control femur position, the knee must track properly over the foot with controlled alignment, and the ankle must provide sufficient dorsiflexion and stable support to let the knee move without inward collapse. This movement challenges neuromuscular control across these joints together, which is why this test assesses their stability in combination. The options with the shoulder, elbow, and wrist refer to upper-body joints that aren’t involved in the squat pattern. The option focusing on the lumbar spine and pelvis addresses core stability but doesn’t capture the essential work of the hip–knee–ankle chain. The knee only choice misses the crucial contributions of both the hip and ankle to maintaining proper alignment and control during the movement.
