|---|---|---|
| Intervention group | Experimental | proprioceptive exercise application. The intervention process will be planned as individualized sessions, 3 days a week, for 30 minutes each, over a period of 4 weeks, and will be conducted under the supervision of a physiotherapist. Receives: Other: Exercise |
| Control group | No intervention | no additional intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Landing Error Scoring System (LESS)
The Landing Error Scoring System (LESS) is an observational assessment tool used to evaluate lower extremity biomechanics during a jump-landing task. Participants perform a standardized jump from a platform and land while their movements are recorded and analyzed based on specific criteria. Higher LESS scores indicate a greater number of movement errors and an increased risk of lower extremity injury, particularly anterior cruciate ligament (ACL) injury. A commonly used cut-off score is ≥5, indicating a higher risk of lower extremity injury, particularly ACL injury.
Measured: t0: baseline t1: at 4 weeks (post-intervention, after 12 sessions)
Secondary outcomes (1)
Joint Position Sense (JPS)
With their eyes closed, the participant is seated with their knee passively brought to a 45° flexion, held for 5 seconds, and then returned to the starting position. The participant is then asked to actively reproduce the same angle. Three repetitions are performed for each leg, and the average absolute angular error (degrees) is calculated. Measurement will be done using a goniometer. There is no universally established cut-off value; higher repositioning error values indicate impaired proprioception.
Measured: t0: baseline t1: at 4 weeks (post-intervention, after 12 sessions)
