Primary |
Change from baseline numerical rating scale for pain (NRSpain) at 4 weeks |
A numerical rating scale for pain (NRSpain) will be used to assess changes in lower body related musculoskeletal pain at rest (now, average over the last week) and during weight bearing activity (like walking) on a range of lowest score of 0 (no pain) to 10 (worst pain) |
Visits 6; one month post enrollment |

Primary |
Change from baseline numerical rating scale for pain (NRSpain) at 6 months |
A numerical rating scale for pain (NRSpain) will be used to assess changes in lower body related musculoskeletal pain at rest (now, average over the last week) and during weight bearing activity (like walking) on a range of lowest score of 0 (no pain) to 10 (worst pain) |

Secondary |
Change from baseline hopping quality (using dominant leg) at 4 weeks |
Quality performance on the hopping three times (using dominant leg) and land on the same limb as far as possible will be scored based on the distance hopped, measured at the level of the great toe on a range of scale 1 (best performance) to 3 (worst performance) |

|
Secondary |
Change from baseline displacement in forward-backward direction during 20 sec of static standing position at 4 weeks |
A markerless motion system will be used. Cameras will be used to collect the backward-forward displacement during 20 sec of static standing on both legs will be analyzed for ability to control static balance. |
