Ice hockey is a high velocity, full body contact sport with great risk of injuries. Concussion is a frequent and common injury in ice hockey. The present study aimed to examine the test results measured with Neurocom Balance Master after concussion in elite ice hockey players. The unilateral stance (US) and limits of stability (LOS) were performed preseason and in the event of concussion 24 hours, 7 days, 14 days and 21 days post injury. 107 male ice hockey players from one elite Swedish team during the seasons 2002/2003 – 2011/2012 where recruited for the study. ANOVA analysis of matched pair test and log test and OPLS-DA modeling and univariate scaled data was performed on the results. The results indicate that both the US and LOS test were not specific enough to predict further concussion and no significance was found when comparing baseline test with tests values after concussion. Perhaps were balance deficits so mild that the tests could not detect them or perhaps was balance was not affected in any higher degree. Except for the movement velocity (MVL) in the LOS test (P < 0,0031*), indicating that players were not fully recovered 7 days post injury, proposing a possible impact at the high-level central nervous system after concussion.
