Abstract
  • Concussion increases the risk of lower extremity injury. This study sought to identify deficits in somatosensory function that may contribute to this heightened risk. Vibratory perception threshold (VPT) and joint position sense (JPS) were compared between individuals with and without a history of concussion. JPS and VPT did not differ between groups (closed kinetic chain (CKC) knee p = 0.093; open kinetic chain (OKC) knee p = 0.255; open kinetic chain ankle p = 0.648). CKC and VPT were correlated at 4 of 5 sites tested (p = 0.009 – 0.033). OKC JPS was not correlated with VPT at any of the 5 sites (p = 0.148 – 0.941), with the exception of the medial femoral epicondyle and the OKC knee measure (p = 0.036). These results do not support our hypothesis. Future research should evaluate the influence of concussion on other characteristics to determine why injury risk is higher following concussion.
