Conclusion The results of this systematic review indicate that motor performance is further impaired by placing a cognitive load on individuals in population s with musculoskeletal injury .
More dem and ing tasks such as gait appear to be more affected in injured individuals than simple balance tasks .
Background Research suggests that individuals with musculoskeletal injury may have difficulty negotiating physical tasks when they are combined with cognitive loads .
Objective Our objective was to conduct a systematic review to underst and the effects of increased cognitive dem and on movement patterns among individuals with musculoskeletal injuries .
Simple decision rules can reduce reinjury risk by 84% after ACL reconstruction: the Delaware-Oslo ACL cohort study
Background Knee reinjury after ACL reconstruction is common and increases the risk of osteoarthritis . There is sparse evidence to guide return to sport ( RTS ) decisions in this population . Objectives To assess the relationship between knee reinjury after ACL reconstruction and ( 1 ) return to level I sports , ( 2 ) timing of RTS and ( 3 ) knee function prior to return . Methods 106 patients who participated in pivoting sports participated in this prospect i ve 2-year cohort study . Sports participation and knee reinjury were recorded monthly . Knee function was assessed with the Knee Outcome Survey — Activities of Daily Living Scale , global rating scale of function , and quadriceps strength and hop test symmetry . Pass RTS criteria were defined as scores > 90 on all tests , failure as failing any . Results Patients who returned to level I sports had a 4.32 ( p=0.048 ) times higher reinjury rate than those who did not . The reinjury rate was significantly reduced by 51 % for each month RTS was delayed until 9 months after surgery , after which no further risk reduction was observed . 38.2 % of those who failed RTS criteria suffered reinjuries versus 5.6 % of those who passed ( HR 0.16 , p=0.075 ) . More symmetrical quadriceps strength prior to return significantly reduced the knee reinjury rate . Conclusions Returning to level I sports after ACL reconstruction leads to a more than 4-fold increase in reinjury rates over 2 years . RTS 9 months or later after surgery and more symmetrical quadriceps strength prior to return substantially reduce the reinjury rate
