Context:The Lower-Extremity Functional Test (LEFT) has been used to assess readiness to return to sport after a lowerextremity injury. Current recommendations suggest that women should complete the LEFT in 135 s (average; range 120–150 s) and men should complete the test in 100 s (average; range 90–125 s). However, these estimates are based on limited data and may not be reflective of college athletes. Thus, additional assessment, including normative data, of the LEFT in sport populations is warranted.Objective:To examine LEFT times based on descriptive information and off-season training habits in NCAA Division III (DIII) athletes. In addition, this study prospectively examined the LEFT’s ability to discriminate sport-related injury occurrence.Design:Descriptive epidemiology.Setting:DIII university.Subjects:189 DIII college athletes (106 women, 83 men) from 15 teams.Main Outcome Measures:LEFT times, preseason questionnaire, and time-loss injuries during the sport season.Results:Men completed the LEFT (105 ± 9 s) significantly faster than their female counterparts (117 ± 10 s) (P < .0001). Female athletes who reported >3–5 h/wk of plyometric training during the off-season had significantly slower LEFT scores than those who performed ≤3 h/wk of plyometric training (P = .03). The overall incidence of a lower-quadrant (LQ) time-loss injury for female athletes was 4.5/1000 athletic exposures (AEs) and 3.7/1000 AEs for male athletes. Female athletes with slower LEFT scores (≥118 s) experienced a higher rate of LQ time-loss injuries than those with faster LEFT scores (≤117 s) (P = .03).Conclusion:Only off-season plyometric training practices seem to affect LEFT score times among female athletes. Women with slower LEFT scores are more likely to be injured than those with faster LEFT scores. Injury rates in men were not influenced by performance on the LEFT.

Functional performance tests, such as the Y Balance Test–Lower Quarter (YBT-LQ), hold promise as screening tools to identify athletes at risk for injury. The ability of the YBT-LQ to discriminate injury risk in Division III collegiate athletes is unknown. The purpose of this study was to determine if preseason YBT-LQ scores are associated with noncontact time-loss lower-quadrant (low back or lower extremities) injury in a heterogeneous population of Division III collegiate athletes. Two hundred and fourteen athletes (females = 104) performed the YBT-LQ test. Preseason YBT-LQ scores, analyzed by the total population, were not associated with noncontact time-loss lower-quadrant injury. Females with greater reach scores in some directions did have a significantly greater risk of injury. This study adds to a growing body of research demonstrating that the YBT-LQ should not be used as a preseason screening tool.

Objectives: Previous research indicates that concussion increases the risk of lower extremity injuries (LE) after return to sport. However, no study has examined the risk of precedent lower extremity injuries and their relationship to the development of a sport related concussion (SRC). To determine if the risk of combined injuries (LE injury-SRC) is elevated in high school athletes accounting for athlete sport and gender. Methods: 33,386 high school athletes were monitored over 4 seasons. 4223 LE injuries and 1132 concussions were reported. Injured athletes were identified by their school athletic trainer (AT) time-loss injury during a team-sponsored practice or game. ATs documented the date, mechanism, and sport of injury. Injured athletes were referred to a board-certified sports medicine physician for diagnoses and follow up care. Cumulative injury rates were calculated with 95% confidence intervals. Rate ratios were used to compare frequency of SRC after RTS following a LE injury. Comparisons were made overall cohort between those participating athletes with and without isolated and combined injuries as well as by gender. (α=0.05). Results: A cumulative incidence for athletes sustaining an isolated SRC was 2.3/100 athletes (95% CI= 2.1-2.5) and for isolated LE injury was 11.5/100 (95% CI=11.2-11.9) athletes. Athletes presenting with a LE injury had an increased risk (RR= 4.7; 95% CI = 4.2-5.2) of sustaining a subsequent SRC within 1 year when compared to athletes that did not suffer precedent LE injuries. Male athletes presenting with a LE injury had an increased risk (RR= 4.9; 95% CI = 4.2-5.7) of sustaining a subsequent SRC within 1 year when compared to male athletes that did not suffer precedent LE injuries. Female athletes presenting with a LE injury had an increased risk (RR= 4.4; 95% CI = 3.6-5.2) of sustaining a subsequent SRC within 1 year when compared to female athletes that did not suffer precedent LE injuries. In football, presenting with a LE injury had an increased risk (RR= 5.8; 95% CI = 4.5-7.4) of sustaining a subsequent SRC within 1 year when compared to football athletes that did not suffer precedent LE injuries. Conclusion: Our results are the first to show that high school athletes who suffer a time-loss LE injury are at 4.4-5.8 times increased risk to suffer a sports related concussion within the next year. Additional studies are warranted to confirm these findings.

Context:Many clinicians use functional-performance tests to determine an athlete’s readiness to resume activity; however, research demonstrating reliability of these tests is limited.Objective:To introduce the Lower Extremity Functional Test (LEFT) and establish it as a reliable assessment tool.Design:Week 1: Subjects participated in a training session. Week 2: Initial maximal-effort time measurements were recorded. Week 3: Retest time measurements were recorded.Setting:The University of Wisconsin–La Crosse (UW-L) and the University of Central Florida (UCF).Subjects:27 subjects from UW-L and 30 from UCF.Main Outcome Measures:Time measurements were analyzed using intraclass correlation coefficients (ICCs).Results:ICC values of .95 and .97 were established at UW-L and UCF, respectively.Conclusions:The LEFT is a reliable assessment tool.
