Sumario:[EN] BACKGROUND: Imbalance or decreased trunk strength has been associated with non-specific low back pain (NSLBP).OBJECTIVE: This systematic review aimed (I) to evaluate the quality of evidence of studies evaluating the reliability of trunkstrength assessment with an isokinetic dynamometer in NSLBP patients, (II) to examine the reliability of trunk strength assessmentusing an isokinetic dynamometer in NSLBP patients and (III) to determine the most reliable protocol for trunk strength assessmentin NSLBP patients.METHOD: PRISMA guidelines were followed. Three databases were used: PubMed, Scopus, and Web of Science with thefollowing keywords: Isokinetic, Dynamometer, Trunk strength testing, Muscle testing, Isokinetic measurement, CORE, Abdominalmuscles, Abdominal wall, Torso, Trunk, Spine, Reliability and, Reproducibility. We included only test-retest studies, focused onthe reliability of isometric and isokinetic strength assessed with an isokinetic dynamometer in NSLBP adults’ patients, publishedin English and from inception to March 30, 2021. The methodological quality was evaluated with the CAT scale and QARELchecklist.RESULTS: Five hundred and seventy-seven articles were retrieved, of which five are included in this review. Three articlesprovide good quality of evidence, the reliability of trunk strength assessment in NSLBP patients is excellent, and the most reliableprotocol for isometric assessment is in a seated position (ICC = 0.94–0.98) and for isokinetic strength in standing position, at60◦/s and 120◦/s (ICC = 0.98).CONCLUSION: There is good quality evidence regarding the trunk strength assessment’s reliability. Reliability is excellent inNSLBP patients; however, a familiarization process should be considered to obtain clinically reliable data. The most reliableprotocol is in a seated position for isometric strength and a standing position for isokinetic strength.
