In Hip ROM #1 Small ROM, what is the positioning of the feet and knees?

• A. Feet flat on floor with knees bent 60 degrees.
• B. Feet on floor with knees around 45 degrees.
• C. Feet in straps, knees lifted around 90 degrees.
• D. Feet in straps with knees extended.

Answer: (C)

The main idea being tested is how using the straps and the knee position control hip isolation during a small-range hip movement. When the feet are in straps and the knees are lifted to about 90 degrees, the legs are anchored, which helps keep the pelvis stable and the spine neutral. This setup lets the hip joints perform a precise, short arc without the movement creeping into the ankles, knees, or lower back. The straps provide consistent resistance and maintain proper alignment, making the hip work in a controlled way. If the feet were flat on the floor with the knees only around 60 degrees or 45 degrees, there wouldn’t be that same leg fixation from the straps, so it’s easier to compensate with the pelvis or lower back and the hip isolation isn’t as clean. If the knees were extended with the feet in straps, the motion would shift toward a different pattern—more hamstring and back involvement—so it wouldn’t reflect the small ROM hip setup intended.
