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 .
Health-related quality of life and direct costs in patients with anterior cruciate ligament injury: single-bundle versus double-bundle reconstruction in a low-demand cohort--a randomized trial with 2 years of follow-up.
PURPOSE To evaluate health-related quality of life ( HRQL ) in patients undergoing anterior cruciate ligament ( ACL ) reconstructive surgery  by use of 2 procedures and to estimate the direct costs of surgery . METHODS We performed a 2-year r and omized , prospect i ve intervention study of 2 surgical ACL reconstruction techniques ( anatomic single bundle [ SB ] v double bundle [ DB ] ) .  Fifty-five consecutive out patients , with a mean age of 30.88 years , were r and omized to SB or DB ACL reconstruction .  The Medical Outcomes Study 36-item Short Form Health Survey ( SF-36 ) was used to measure HRQL ( primary outcome ) . ACL injuries were assessed by the International Knee Documentation Committee ( IKDC ) score ( secondary outcome ) . The use of medical re sources and their costs were evaluated . RESULTS We included 52 patients in the final analyses ( 23 in the SB group and 29 in the DB group ) . At baseline , there were no significant differences in study variables . At 2 years of follow-up , there were no significant differences in SF-36 and IKDC scores between groups . However , compared with baseline , the SF-36 physical function , physical role , bodily pain , social function , and emotional role scores were significantly better in the SB group ( P < .05 ) , whereas only the physical function dimension score was better in the DB group ( P = .047 ) . IKDC scores at 2 years improved significantly in the SB group ( P < .001 ) and DB group ( P = .004 ) compared with baseline . There was a significant correlation between the SF-36 physical function , physical role , and bodily pain dimensions and the IKDC score at 2 years ( P < .05 ) . The costs were € 3,251 for the SB group and € 4,172 for the DB group . CONCLUSIONS HRQL and medical outcomes were similar between SB and DB ACL reconstruction techniques , 2 years after surgery . However , the SB technique was more cost-effective
