Single Leg Squat Test and Its Relationship to Dynamic Knee Valgus and Injury Risk Screening

Abstract

The SLS test is a reasonable tool to use in preparticipation sports physical examinations to assess for dynamic knee valgus and the potential risk of lower extremity injury.

Single-leg squats can predict leg alignment in dancers performing ballet movements in “turnout”

“…This finding supports the presumption that the leg alignment during single-leg squats can predict the leg alignment dancers exhibit during “turned out” ballet movements. This study also supports previous reports of the positive relationship between single-leg squats and leg alignment during landings in athletic populations 14,15. These findings warrant the use of the single-leg squat in prospective dance injury surveillance etiological studies as a means to assess dancer functional leg alignment.…”

Evaluating Performance of the Single Leg Squat Exercise with a Single Inertial Measurement Unit

“…It is often used to identify risk factors for and rehabilitate lower limb injuries such as patellar tendonopathy and anterior cruciate ligament injury [10,11]. This is because the SLS provides a simple test of knee alignment during weight bearing activities as well as identifying deficiencies in core strength, landing, running and cutting tasks [8]. Furthermore, it requires no equipment to complete meaning it can be used in a clinical setting easily [10].…”

Evaluating Eccentric Hip Torque and Trunk Endurance as Mediators of Changes in Lower Limb and Trunk Kinematics in Response to Functional Stabilization Training in Women With Patellofemoral Pain

“…40,42 Before testing, 5 electromagnetic tracking sensors were attached to the sternum, sacrum (S2), and midlateral thighs and medial to the tibial tuberosity using double-sided adhesive tape. The kinematics data were collected at a sampling rate of 90 Hz.…”
