What happens in Hip ROM #6 Single Leg Series?

• A. Remove one strap. One leg works while the other knee pulls toward chest or leg extends. Versions include knee to chest, legs extended, and external rotation.
• B. Both legs work simultaneously with a single strap.
• C. Lying on back with both knees bent.
• D. Standing balance on one leg.

Answer: (A)

Isolating one leg to move the hip through its range of motion while the other leg stays stable is what the hip ROM single leg series trains. In this setup you remove one strap so only the working leg is loaded, allowing focused unilateral hip articulation. The working leg can move in several ways: knee pulled toward the chest to emphasize hip flexion with the knee in, keeping the leg extended for a straight-leg hip flexion/extension pattern, or rotating the thigh outward to work external rotation. This approach emphasizes pelvic stability and control of the working hip as it goes through different ranges. The other options describe setups that involve both legs, a different position, or a standing balance task, none of which fit the single-leg, strap-isolated sequence.
