Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Change in Walking Speed Assessed by the 10-Meter Walk Test

  Walking speed will be assessed on a 14-meter walkway. The first 2 meters will be used for acceleration and the final 2 meters for deceleration. The time required to walk the middle 10 meters at a comfortable speed will be recorded in seconds using a digital stopwatch. Walking speed will be calculated in meters per second. The test will be performed twice, and the mean value will be used. Higher walking speed indicates better walking performance.

  Baseline (preoperative), postoperative Week 7, postoperative Week 13, and postoperative Week 15.

Secondary Outcomes (5)

• Lower-Extremity Function

  Baseline (preoperative), postoperative Week 7, postoperative Week 13, and postoperative Week 15.

• Change in Kinesiophobia Assessed With the Tampa Scale for Kinesiophobia

  Baseline (preoperative), postoperative Week 7, postoperative Week 13, and postoperative Week 15.

• Change in Body Awareness Assessed With the Body Awareness Questionnaire

  Baseline (preoperative), postoperative Week 7, postoperative Week 13, and postoperative Week 15.

• Change in Quadriceps Muscle Strength Assessed With a Handheld Dynamometer

  Baseline (preoperative), postoperative Week 7, postoperative Week 13, and postoperative Week 15.

• Change in Pressure Pain Threshold Assessed With a Pressure Algometer

  Baseline (preoperative), postoperative Week 7, postoperative Week 13, and postoperative Week 15.

Study Arms (2)

Video Feedback-Supported Rehabilitation

EXPERIMENTAL

Participants will receive 40 minutes of conventional physiotherapy and 10 minutes of video feedback-supported gait training per session, 5 days per week throughout the distraction phase.

Behavioral: Video Feedback-Supported Gait Training; Other: Conventional Physiotherapy

Conventional Physiotherapy

ACTIVE COMPARATOR

Participants will receive 50 minutes of conventional physiotherapy per session, 5 days per week throughout the distraction phase.

Other: Conventional Physiotherapy

Interventions

Video Feedback-Supported Gait Training BEHAVIORAL

Participants will be recorded while walking on a 10-meter walkway in the frontal and sagittal planes. They will review the recordings with the physiotherapist and receive standardized visual and verbal feedback regarding step width, step symmetry, trunk alignment, pelvic position, Trendelenburg sign, lower-extremity movements, foot contact, and gait rhythm. The intervention will be administered for 10 minutes per session, 5 days per week throughout the distraction phase.

Video Feedback-Supported Rehabilitation

Conventional Physiotherapy OTHER

Conventional physiotherapy will include active and passive range-of-motion exercises, quadriceps and hamstring stretching, isometric strengthening exercises, gait training, and neuromuscular electrical stimulation. The experimental arm will receive 40 minutes and the active comparator arm will receive 50 minutes per session, 5 days per week throughout the distraction phase.
