Wall Chair Exercise

Both isometric wall squat volumes immediately reduced pain sensitivity in adults with knee osteoarthritis. The trial compared a single-repetition isometric wall squat, a multiple-repetition isometric wall squat, and quiet sitting control. The single-repetition protocol used one wall squat held for up to 3 minutes or until volitional fatigue at 100 degrees of knee flexion. The multiple-repetition protocol used three repetitions of the same wall squat hold with 30 seconds rest between repetitions. The starting position requires standing with the back against a wall and lowering into a wall-sit. The wall chair exercise uses a wall, a chair, and a small ball placed between the knees. The exercise has five key positional checkpoints including ball squeeze, posterior pelvic tilt, heel weight, flat low back, and diamond hand press. The single-repetition wall squat protocol is presented as practically accessible for patients with functional limitations.
