Objectives: To identify, critically appraise and synthesize the reported psychometric properties of the Single Assessment Numeric Evaluation in patients with lower extremity pathologies. Data sources: Medline, Embase, Scopus and CINAHL databases from inception till May 2019 were searched. Study selection or eligibility criteria: Studies that included patients with lower extremity pathologies that reported on the measurement properties of the Single Assessment Numeric Evaluation were included. Data extraction: Individual studies were appraised by two independent authors to summarize the quality of available evidence, using the COSMIN 2018 guidelines for systematic reviews of patient reported outcome measures. The results were descriptively summarized and reported. Data synthesis: Nine eligible studies were included. The Single Assessment Numeric Evaluation reliability measures indicated coefficients of variation <1% (doubtful quality; indeterminate properties). Validity measures displayed correlations of 0.51–0.88 between the Single Assessment Numeric Evaluation and International Knee Documentation Committee, Western Ontario/McMaster Universities Osteoarthritis Index, Knee Outcome Survey, and Revised Foot Function Index. Two measurement studies assessed the Single Assessment Numeric Evaluation responsiveness measures. Effect sizes of ≥1.75; and minimal clinically important differences of 7.0 (6 months) and 19.0 (12 months) follow ups were reported. Conclusion: Adequate quality evidence with sufficient measurement properties demonstrated that the Single Assessment Numeric Evaluation is a valid tool in assessing perception of condition in female participants with knee injuries and in military population patients with ankle sprains.Implications for rehabilitation Single Assessment Numeric Evaluation is a valid and responsive tool in assessing perception of condition in female participants with knee injuries. Single Assessment Numeric Evaluation is a valid tool in assessing perception of condition in military population patients with ankle sprains.
