Video Feedback-Supported Rehabilitation After Bilateral Femoral Lengthening

This randomized controlled study aims to investigate the effects of adding video feedback-supported gait training to a standard rehabilitation program in individuals undergoing cosmetic bilateral femoral lengthening surgery.

A total of 32 adults aged 18-45 years who undergo cosmetic bilateral femoral lengthening using the Lengthening Over Nail (LON) technique will be included. All surgical procedures will be performed at Private Esencan Hospital. Participants will be monitored at the hospital for the first 6 postoperative days, and the distraction phase will begin on postoperative day 7. After discharge, rehabilitation will continue at BNB Health Services and Consultancy Center.

Participants will be assigned to an intervention group or a control group using block randomization at a 1:1 ratio. Both groups will receive rehabilitation 5 days per week, with each session lasting 50 minutes. The control group will receive 50 minutes of conventional physiotherapy. The intervention group will receive 40 minutes of conventional physiotherapy and 10 minutes of video feedback-supported gait training.

Assessments will be performed before surgery (T0), when approximately 4 cm of lengthening has been achieved (T1), when approximately 8 cm of lengthening has been achieved (T2), and 2 weeks after removal of the external fixator (T3).

The primary outcome will be walking performance assessed using the 10-Meter Walk Test. Secondary outcomes will include lower-extremity function, kinesiophobia, body awareness, quadriceps muscle strength, and pressure pain threshold.
