About

In this study, the investigators aimed to investigate the relationship between the dynamic valgus index and the dynamic valgus index during the landing phase of the single leg squat movement of sedentary people according to gender and to evaluate the effect of the postural alignment of the ankle and foot complex on the stability of the knee joint during the single leg squat.

Full description

Single leg squatting is the basis of many functional activities such as walking, running, landing and balance. Single leg squat is generally preferred for lower extremity rehabilitation and assessment of dynamic hip joint control, lower extremity kinematics and lower extremity alignment. Many studies have used single leg squats for knee kinematics assessment. Excessive knee valgus, hip adduction and abduction of the knee joint during the single leg squat pose a risk of injury to the anterior cruciate ligament, medial collateral ligament and other ligaments.

The single-leg squat test is frequently used clinically to provide a simple and convenient assessment of neuromuscular control for the lumbo-pelvic region. Misalignment of the lower limb can affect knee and hip kinematics during athletic movements, causing disorders such as anterior cruciate ligament lesions, iliotibial band syndrome and patellofemoral pain syndrome. The single leg squat test is a clinical functional test commonly used to assess clinical abnormal movement patterns of the lower limbs in terms of kinetic chain or coordinated muscle activity. This scale provides assessment of five dimensions: general impression, trunk posture, pelvis in space, hip joint movement and knee joint movement. Since the single-leg squat test tests both daily activity and lower limb balance ability during athletic tasks, it was deemed appropriate to perform it separately on both legs. It is a valid and reliable test preferred in the literature as a functional test that evaluates lower extremity and especially knee joint balance skills.

In the light of this information, the aim of this study was to investigate the relationship between the dynamic valgus index and the dynamic valgus index during the landing phase of the single leg squat movement of sedentary people according to gender and to evaluate the effect of the postural alignment of the ankle and foot complex on the stability of the knee joint during the single leg squat.
