Table 3.
Gait measures (mean ±SD) for experimental and contralateral legs in Loaded and Sham groups with the varus loading device (VLD) engaged (compressive overload applied) and disengaged (no compressive overload applied). There were no significant differences between the Loaded and Sham groups and no significant differences between the VLD being engaged and disengaged for the Loaded or Sham groups.
