Primary Outcome Measures:
  • Change From Baseline in the SF-36 Physical Component Summary (PCS) Score of the Short Form-36 (SF-36) [ Time Frame: Over 365 days ]
    Assessments at baseline and 6 post baseline time points/ mixed effects repeated measure single point estimate. Range= -100 worst, 0 best

  • Time (Days) to Radiographic Healing of Tibial Fractures [ Time Frame: over 365 days ]
    Days from randomization to day of x-ray assessed healed or, if not healed, day of premature withdrawal/study termination or day 365 (end of study visit)/ Kaplan-Meier

Other Outcome Measures:
  • Treatment Compliance [ Time Frame: Treatment period: Days from randomization to day of x-ray assessed healed or, if not heal, day of premature withdrawal/study termination or day 365 (end of study visit) ]
    The percent of subjects who used the device greater than or equal to 18 minutes per day over 80% of the days in their treatment period.
