What this trial measures

  • Clinical outcomes (pain)6-weeks leading up to the Boston Marathon, or 6-weeks post completion of Boston Marathon

    Pain will be assessed for current pain and worst pain in the previous week using a 10-cm visual analog scale (VAS; 0=no pain; 10=worst pain imaginable), a reliable, valid, and responsive tool for evaluating treatment outcomes for patellofemoral pain.

  • Clinical outcomes (self-reported function)6-weeks leading up to the Boston Marathon, or 6-weeks post completion of Boston Marathon

    Self-reported function will be evaluated using the 11-item Knee Injury and Osteoarthritis Outcome Score-Patellofemoral subscale (KOOS-PF; 0=extreme disability; 100=no disability), a reliable tool with the highest content validity for patellofemoral pain.

  • Clinical outcomes (global rating of change)6-weeks leading up to the Boston Marathon, or 6-weeks post completion of Boston Marathon

    Global rating of change will be assessed for perceived recovery using a 7-point Likert scale (much worse, worse, slightly worse, no change, slightly better, better, or much better). The global rating of change scale is a reliable, clinically relevant, and patient-centered measure for interpreting meaningful improvements.
