Effectiveness of Different Exercise Programmes in Individuals With Dynamic Knee Valgus

hazal genc38 enrolled

Overview

Dynamic knee valgus (DDV) is an erroneous movement pattern of the lower limb that occurs in multiple planes. It results from a combination of hip joint adduction, femoral anteversion, knee abduction and external tibial torsion . DDV is also referred to as a mechanism in which the knee joint moves medially relative to the hip and foot with the centre fixed to the ground.

Outcomes

Primary Outcomes

Frontal Plane Projection Angle (FPPA)

FPPA is measured as the angle between a line drawn from the marked point on the proximal thigh to the knee joint and another line extending from the knee joint to the ankle during maximum knee flexion. A 2D analysis is performed through single-leg squat (SLS), vertical jump (VJ), and single-leg landing (SLL). An increase of 10° or more in FPPA during a single-leg squat is categorized as "Observable Dynamic Knee Valgus (DKV)."

Time frame: 6 weeks

Lower Extremity Clinical Measurements

Clinical measurements help assess the functional performance of the lower extremities and prevent injuries. Key parameters include Q-angle, hip anteversion angle, tibial torsion, ankle dorsiflexion, and rearfoot angle. Standardized tests such as goniometer-based Q-angle measurement, Craig's test for hip anteversion, and subtalar joint neutral positioning for dorsiflexion are utilized.

Time frame: 6 weeks

Balance Evaluation

Static balance was assessed with the Single Leg Stance Test (SLST), while dynamic balance was evaluated using the Y Balance Test (YBT) in three directions: anterior, posteromedial, and posterolateral.

Time frame: 6 weeks

Proprioception Assessment

Proprioception was evaluated using the Active Joint Position Sense (AJPS) test, which measures the ability to replicate a target angle. Measurements were conducted with a Baseline digital goniometer, and angular deviation was recorded to determine accuracy.

Time frame: 6 weeks
