Osteoarthritis (OA) is the most prevalent form of arthritis in the elderly. It is estimated that 7% of men and 11% of women over the age of 65 have KOA. The most significant symptoms of the disease are pain and functional disability.

This study has two aims:

  1. To characterise the gait patterns and clinical parameters of patients with knee osteoarthritis (KOA) in Singapore at baseline, prior to treatment.
  2. To investigate the changes in gait patterns and the clinical benefits of treatment with a new biomechanical device, AposTherapy, for patients with KOA.

Primary Outcome Measures:
  • Changes in self-evaluation questionnaires between baseline and after 6 months of therapy [ Time Frame: Baseline, 6 months ]

    Western Ontario and MacMaster osteoarthritis questionnaire (WOMAC) and SF-36 Health Survey will be evaluated.

    The WOMAC questionnaire is measured on a 10cm visual analogue scale (VAS) and the SF-36 is scored between 0-100.

Secondary Outcome Measures:
  • Changes in spatio-temporal gait parameters between basline and after 6 months of therapy [ Time Frame: Baseline, 6 months ]

Enrollment: 60
Arms Assigned Interventions
