Single-leg Squat (Kivlan & Robroy, August 2012) (Frohm, Heijne, Kowalski, Svensson, & Myklebust, November 2010)
Purpose: Evaluate hip strength, core control and stability of the lower limb including the knee and ankle. This test is most specific in identifying the movement pattern consisting of hip adduction and internal rotation that results in knee valgus. Knee valgus has been proposed as a risk factor for patellofemoral painsyndrome, iliotibial band friction syndrome, and anterior cruciate ligament injury and can be a contributing factor to persistent low-back pain.
Start: Stand on one leg with non-stance leg lifted off the ground so that the knee is flexed to approximately 90°. Hold hands on hips or alternately across chest.
Movement: Squat down as far as possible without losing balance. You should try to get close to 60 degrees knee flexion (90 degrees is horizontal to floor, so less than this). Complete the squat and return to the start position in less than 6 seconds.
Criteria:
- Knee bends to 60 degrees
- Knee in line with second toe, moving forward past end of foot
- Pelvis level in horizontal line
- The upper body is vertical with no leaning forward or to the side
3 points: All criteria must be fulfilled with 60 degrees knee flexion.
2 points: Hip, knee, pelvis and foot aligned, but unable to achieve 60 degrees knee flexion.
1 point: Unable to maintain alignment criteria or loss of balance.
