New Manual Test for Hip Abductor Extensibility

The intervention consists of a new manual test for assessing iliotibial band (ITB) tension and hip abductor extensibility. The patient lies supine on the edge of a treatment table with the non-tested leg flexed at the hip and knee, stabilizing the pelvis. The tested leg remains extended. The examiner stabilizes the non-tested leg with one hand and adducts the tested leg until a resistance is felt, ensuring no pain. The hip adduction angle is visually assessed and recorded. A subset of participants also undergoes the modified Ober test for comparison. Inertial motion sensors are used to validate the accuracy of visual assessments. The primary outcomes include intra-rater and inter-rater reliability, while secondary outcomes evaluate the test's accuracy and pelvic movement reduction.
