Brief Summary

A variety of biomechanical gait modification interventions can elevate knee loading and improve knee symptoms in knee osteoarthritis patients. However, there was a lack of acceptability and adherence regarding modification interventions without any explanation. Thus, this study investigates the feasibility and acceptability of foot insoles as a gait modification tool among Saudi Arabian knee osteoarthritis patients and physiotherapists. This study aims to answer the following:

  • Which gait modification intervention is most likely to be implemented in Saudi Arabia (SA) clinical practice, taking context, patients' clinical and research evidence into consideration?
  • In Saudi Arabia, can this proposed foot-insole intervention be implemented? Is there sufficient experience among physiotherapists regarding gait modification to deliver it, and will patients engage with it? How can KOA rehabilitation outcomes be evaluated in the future? The participants will be conducted over three phases:
  • The patients' interview and therapists' focus group discussion will be used to examine KOA patients' and clinicians' perspectives on enabling and accepting gait modifications in phase 1.
  • The feasibility study will explore how a small number of KOA patients tolerate gait modifications and consider the most relevant outcome measures, such as pain and function, in phase (2).
  • A small group of knee osteoarthritis patients and their physiotherapists who participated in phase (2) will be asked to participate in a descriptive survey in phase (3). To examine the acceptability and feasibility of the study intervention in phase (2).

Outcome Measures

Primary Outcomes (4)

  • Pain level

    The change from baseline pain intensity level at 6-weeks, based on the nine points of a visual analogue scale, where 0 represents (no pain) and 9 represents (worst pain).

    6 weeks post-intervention.

  • Western Ontario and McMaster Universities Arthritis Index-total

    The change from baseline pain, stiffness and physical activity levels at 6-weeks. Each question is scored from 0 to 4, which are: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). Scores are summed for each subscale, ranging from 0-20 for pain, 0-8 for stiffness, and 0-68 for Physical Function. A higher WOMAC score indicates worse pain, stiffness, and functional limitations.

    6 weeks post-intervention.

  • Likert scale

    Measuring knee osteoarthritic subjects' satisfaction based on the 5 point Likert scale survey.

    6 weeks post-intervention.

  • Likert scale

    Measuring therapists' agreement based on the 5-point Likert scale survey.

    6 weeks post-intervention supervision.

Feasibility intervention

EXPERIMENTAL

The intervention will be foot insole (lateral wedge) insole, which has already been delivered in routine UK NHS and SA environments by at least one physiotherapist. Clinical testing will be done with 15-25 knee osteoarthritis subjects. These individuals will be assigned to a single intervention group for 4-6 weeks of re-gait training intervention. It involves a personalised gait retraining programme (sizable insole) for the KOA subjects to evaluate the impact on knee pain and improve function. It is set within 4-6 weeks of VAS and the WOMAC tools for knee pain \& function outcome.

Device: Lateral Wedge insole

Interventions

Insoles with lateral wedges are placed in patients' shoes to control biomechanical knee loading on the medial side of the knee. Insoles with lateral wedges are designed to be thinner on the inside (medially of the foot) and thicker on the outside (laterally of the foot) to relieve knee biomechanical loading parameters.

Model Details: A gait modification (Lateral wedge insole) program will be conducted over 4 to 6 weeks in the physiotherapy gym or adjusted treadmill and outside the clinic during the day (at least 8 hours per day). * During the session, the researcher will observe participants inside the clinic and ensure that the modified gait application is applied, and outside the clinic will be followed by telephone. * Participants will walk on the gym floor or an adjusted treadmill for at least 15 to 20 minutes during each session. Participants will be instructed to use the mirror for feedback and achieve the target modified gait procedure. However, it will be emphasised gait modification procedures exhibited at baseline pain and function, and then at the end of the trial, it will focus on subjects' acceptability.
