Return to Sports after Lower Extremity Injuries:Assessment of Movement Quality

Numerous high performance athletes experience further damage or recurrent injuries even after successful rehabilitation. This is often caused by an insufficient movement quality, which has been very rarely assessed by test protocols which determine the point of reintegration into high performance sports (Return-to-Play, RTP). In order to assess the movement quality both objective and subjective test protocols exist. Objective methods like 3D-movement analysis are viewed as international gold standard, but are not the most practicable solutions for daily training routine. This study aims at reviewing the available literature on reliability and validity of existing subjective test protocols. Further their use within high-performance sports is evaluated. Up to now subjective methods fail to match sufficient validity. However some practical approaches for assessment of movement quality after injury are known. Based on selected criteria first recommendations for the use of different subjective screening test methods are given. In summary further research focusing on the validity of subjective tests is needed. The subjective testing methods should be used in combination with additional tests (e.g. strength testing) in order to identify other risk factors. Recurrent pre-injury screenings on movement quality should be carried out to enhance injury prevention.
