The goal of this project is to assess the effects of an ankle strap on the effectiveness of a laterally-wedged insole with ankle strapping in reducing knee symptoms and improving static and dynamic lower limb biomechanics. Using a repeated measures, modified cross-over design, the following aims and hypotheses will be addressed:
- Use of the insole with ankle strapping significantly alters hip-knee-ankle (HKA) angle towards 180° or talar valgus angulation.
- Use of the insole with ankle strapping significantly reduces peak knee external varus moment during gait.
- Use of the insole with ankle strapping significantly reduces foot external rotation (out-toeing) or widened base during gait analysis.
- The radiographic HKA angle and tilt angle of the talus will predict knee peak external varus moment during gait.
1. The use of an insole with ankle strapping over a two-week period will reduce knee pain (Visual analogue scale, and Knee Osteoarthritis Outcome Survey).
