-Summary

This study aims to investigate the effects of a structured physical therapy and rehabilitation program on gait temporospatial parameters and plantar pressure distribution in patients who have undergone total knee replacement surgery.

Patients undergoing total knee replacement often experience alterations in gait patterns and weight distribution, which may affect functional mobility and recovery outcomes. This study will evaluate whether a targeted rehabilitation program can improve walking performance and restore more symmetrical plantar pressure distribution.

Participants will be assessed before and after the intervention using objective gait analysis and plantar pressure measurement tools. The findings of this study may help improve rehabilitation strategies and enhance functional recovery following knee replacement surgery.

Physical Therapy Rehabilitation (Other): A structured physical therapy rehabilitation program including range of motion exercises, muscle strengthening, balance training, and gait training aimed at improving functional mobility and gait performance.

+Outcome measures

Primary outcomes

Cadence (steps/minute) measured using gait analysis system [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: Cadence will be measured using a gait analysis system. The average number of steps per minute will be calculated for each participant.
Peak pressure [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: kPa
Postural Alignment [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: The REEDCO Posture Sheet
Quadriceps Muscle Strength (MMT score 0-5) [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: Muscle strength will be assessed using Manual Muscle Testing (MMT) graded from 0 to 5.
Circular measurement of quadriceps (cm) [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: To evaluate the degree of muscle wasting (atrophy), hypertrophy, or the degree of oedema and joint swelling
Walking speed (velocity) [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: m/sec
Step and Stride time [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: Seconds
Step and Stride length [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: cm
Toe In/Out [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: Degree
Base Of Support (BOS) [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: cm
Average Pressure [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: kPa
Gradient Pressure [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: kPa
Hamstring Muscle Strength (MMT score 0-5) [Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)]: Muscle strength will be assessed using Manual Muscle Testing (MMT) graded from 0 to 5.
