RESUMO
BACKGROUND: Risk factors for different sports injuries vary between sexes. Deficits in postural stability have been associated with several lower extremity injuries. The purpose of this study was to examine the differences in static postural stability between male and female intercollegiate athletes with and without visual information. # HypothesisThere will be no difference in visual reliance between sexes during static postural stability. STUDY DESIGN: Cross-sectional Study. METHODS: Static postural stability was assessed during a single session for football, soccer, basketball, and volleyball intercollegiate athletes (males, n=135, females, n=51) under eyes open (EO) and eyes closed (EC) conditions via performance of single limb stance on a force plate. Ground reaction force component data in all directions were quantified as a unitless composite score (COMP) where lower values indicated better postural stability. The absolute change and percentage change between EO and EC conditions were calculated for each sex. Two-sample Kolmogorov-Smirnov tests were used to compare differences between sexes. RESULTS: Males had greater EO COMP (males=7.77±3.40; females=6.48±4.61; p=0.038; Cohen's d=0.343) and EC COMP (males=19.43±8.91; females 14.66±6.65; p=0.001; Cohen's d=0.571) than females. A significant difference in absolute change from EO to EC was observed between sexes (males=-11.65±7.05; females=-8.18±5.61; p=0.01, Cohen's d=-0.520) indicating that males had a greater change between conditions for the worse. There was no significant difference in percent change from EO to EC between sexes (males=159.2±90.7; females=156.7±109.2; p=0.39; Cohen's d=0.026). CONCLUSIONS: The observed differences between males and females in EO COMP, EC COMP, and absolute difference in COMP indicate that there is some factor that causes a difference in static postural stability between sexes. No difference in percent change between groups indicates that the difference in static postural stability between sexes may not be due to visual reliance. Female athletes may inherently have better postural stability than males, but both sexes were able to compensate for the loss of visual input. LEVEL OF EVIDENCE: 3.
RESUMO
OBJECTIVE: To evaluate the reporting of rehabilitation guidelines in studies of postoperative outcomes of patients with femoroacetabular impingement (FAI) syndrome and/or labral tear. DESIGN: Scoping review. LITERATURE SEARCH: A computer-assisted literature search was conducted of the MEDLINE, CINAHL, and Embase databases on June 17, 2018. Using key words related to FAI syndrome/labral tear and both open and arthroscopic surgical outcomes, we identified 169 studies that included 16 675 patients. Separate authors calculated and verified the prevalence of reported outcomes. STUDY SELECTION CRITERIA: We included intervention and observational studies that were prospective or retrospective in design. Studies must have included patients with a primary diagnosis of FAI syndrome and/or labral tear. DATA SYNTHESIS: We calculated the mean ± SD prevalence for continuous variables, where possible. RESULTS: Hip arthroscopy was the primary surgical procedure (76% of studies). The mean ± SD age of participants was 34.8 ± 9.2 years and the mean ± SD follow-up time was 27 ± 15.3 months. Of the 169 included studies, 74 (44%) discussed phases of rehabilitation, 49 (29%) reported details on goals between phases, 1 in 3 described details on rehabilitation progression, and fewer than 1 in 10 reported sufficient detail to replicate the rehabilitation protocol. Weight-bearing and range-of-motion restrictions were poorly reported and variable in duration. CONCLUSION: Surgical outcome studies do not provide sufficient detail or consistency for practicing clinicians to replicate a postoperative rehabilitation protocol for patients with FAI syndrome/labral tear.
