  "description": "Sustained adductor and inner hip stretch in a wide-knee quadruped position. Patient kneels with knees spread wide, feet turned outward, and sinks hips toward the floor. Provides a prolonged stretch to the adductor group and hip internal structures. Effective for improving hip abduction ROM and addressing adductor tightness.",
