RESUMEN
CONTEXT: Strength ratios are important because imbalances in opposing muscle groups can cause articular instability and subsequently increase the risk of musculoskeletal injury (MSKI). Therefore, the purpose of this study was to evaluate the association between lower extremity (LE) musculoskeletal isometric strength ratios and the history of LE MSKI. PARTICIPANTS: One hundred eighty-two NCAA Division 1 soccer, football, volleyball, and basketball athletes. INTERVENTIONS: All isometric strength assessments were measured bilaterally using a handheld dynamometer. Strength assessments included: ankle inversion/eversion, ankle dorsiflexion/plantarflexion, knee flexion/extension, hip abduction/adduction, and hip external/internal rotation. LE MSKI history was collected through self-report; a report of the LE MSKI sustained in the one year prior to testing were collected. RESULTS: The hip external/internal rotation ratio was statistically significant for side to side differences in the non-injured (NINJ) group (p = 0.001). The dominant leg of the NINJ group had a mean external/internal rotation ratio of 1.109 ± 0.221, and the non-dominant leg had a mean ratio of 1.177 ± 0.208. CONCLUSIONS: There were no statistically significant differences between the injured (INJ) and NINJ groups. This could indicate that injury history does not play a role in current strength ratios and could suggest that the athletes in the INJ group are performing successful rehabilitation for their injuries.

OBJECTIVES: To provide a comprehensive overview of the measurement properties of patient-reported outcome measures (PROMs) used to assess sleep quality in adult patients with prevalent pain-related conditions. METHODS: Without language restrictions PubMed, Scopus, and Embase were searched from their inception to January 2020. Independent reviewers screened and selected studies, extracted data, assessed the methodological quality using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) Risk of Bias checklist, and performed an evidence synthesis for each measurement property. The results were classified as sufficient, insufficient, inconsistent, or indeterminate, and quality of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: Nineteen studies were included investigating twelve PROMs and six pain-related conditions. Reliability, internal consistency, structural and construct validity were the most prevalent measurement properties investigated across the studies. Three questionnaires were investigated in more than one study (Jenkins Sleep Scale [JSS] and Pittsburgh Sleep Quality Scale [PSQI] and the Medical Outcomes Study-Sleep Scale [MOS-SS]). High-quality evidence was reported for sufficient content validity in the JSS and indeterminate responsiveness in the MOS-SS. Moderate to high evidence was reported for sufficient structural validity in the MOS-SS and PSQI and sufficient and insufficient construct validity in the JSS And MOS-SS. Low to high evidence was reported for sufficient internal consistency in the MOS-SS and PSQI, while low to moderate evidence for sufficient reliability in the JSS, MOS-SS, and PSQI. CONCLUSION: Studies reporting the most measurement properties included the JSS, MOS-SS, and PSQI in multiple prevalent pain-related conditions. Given this, not all measurement properties have been reported for these as well as other questionnaires, and much investigation is needed to ensure the quality of these questionnaires within high prevalence chronic pain conditions.
