Effect of Physical Therapy Rehabilitation on Gait and Plantar Pressure in Patients After Total Knee Replacement

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.

Treatment and study plan

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.

Primary outcomes

  1. Cadence (steps/minute) measured using gait analysis system

    Time frame: 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.

  2. Peak pressure

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    kPa

  3. Postural Alignment

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    The REEDCO Posture Sheet

  4. Quadriceps Muscle Strength (MMT score 0-5)

    Time frame: 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.

  5. Circular measurement of quadriceps (cm)

    Time frame: 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

  6. Walking speed (velocity)

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    m/sec

  7. Step and Stride time

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    Seconds

  8. Step and Stride length

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    cm

  9. Toe In/Out

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    Degree

  10. Base Of Support (BOS)

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    cm

  11. Average Pressure

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    kPa

  12. Gradient Pressure

    Time frame: Baseline and after completion of the rehabilitation program (e.g., 6-10 weeks)

    kPa

  13. Hamstring Muscle Strength (MMT score 0-5)

    Time frame: 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.
