The Single Leg Squat Test is used to identify hip strength deficits. Hip strength is an integral part of knee alignment and injury prevention. Athlete stands on a box or step with hands on hips and performs 5 consecutive single leg squats on each leg. Athlete must squat as low as possible and maintain balance throughout all 5 squats (see figure 1). If one hip drops lower than the other (figure 2), the knee of the stance leg points inward (figure 3), or the athlete has difficulty maintaining balance and good posture (figure 4), this may be an indication of poor hip strength.
