Brief Summary:
A prospective, interventional, randomized, double-arm clinical evaluation study to examine the efficacy of AposTherapy® versus a control group, in the short-term at 6 months and in the long-term at 12 months post-treatment, with the primary efficacy assessment based on improvement in knee pain score and improvement in function in patients following diagnosis of knee osteoarthritis (OA).

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 77 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Phase I - A prospective, interventional, randomized, double-arm clinical evaluation of patients who have been diagnosed with OA of the knee. The active treatment arm (personally calibrated biomechanical device) will be compared to a control arm (sham-placebo device) (similar shoes without biomechanical elements).

Phase II - Open-label, cross-over study design. After the completion of phase one patients will be un-blinded to their group allocation. Patients that were allocated to the sham-placebo control group will cross to the active group and will receive the AposTherapy treatment. Patients that were allocated to the active group will continue with treatment.

Masking: None (Open Label)
Primary Purpose: Treatment

Arm Intervention/treatment
Experimental: Active Treatment Arm
Personally calibrated bio-mechanical device
Device: Calibrated AposTherapy®
a biomechanical device including 2 hemispheric biomechanical elements attached to a platform in a form of a shoe. the biomechanical device is calibrated to each patient by a physiotherapist specialized with the treatment methodology.

Placebo Comparator: Control Arm
sham-placebo device (similar shoes without bio-mechanical elements).
Device: Non-Calibrated Sham Apos Therapy Device
The comparator group will receive a non-calibrated sham device.




Primary Outcome Measures :
  1. Western Ontario and McMaster University (WOMAC) Total Score [ Time Frame: screening, 3 months, 6 months, 9 months, and 12 months ]
    WOMAC evaluates the condition of patients with osteoarthritis of the knee and hip, including pain, stiffness, and physical functioning of the joints. In this study, WOMAC scores were recomputed as the sum within sub-scales (pain score is the sum of questions 1-5; stiffness is the sum of questions 6-7; functional score is the sum of questions 8-24). The total score is reported as the sum of the pain, stiffness, and functional sub-scores for all participants. The total score range is 0-1292. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.


Secondary Outcome Measures :
  1. Visual Analog Score (VAS) Score [ Time Frame: 12 Months ]
    The visual analogue scale or visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured.

  2. Short-Form 36 (SF-36) Total Score [ Time Frame: screening, 3 months, 6 months, 9 months, and 12 months ]
    The Short Form (36) Health Survey is a 36-item, patient-reported survey of patient health. The survey consists eight scaled scores; the scores are weighted sums of the questions in each section. Scores range from 0-100, with lower scores = more disability and higher scores = less disability. Therefore, higher scores represent better health.
