ObjectiveThis study aimed to develop and assess additional effects of brief self-exercise education (brief-See) for individuals with chronic low back pain (CLBP). The brief-See comprised 100-minute consultation, individualized self-exercise program, and direct short teaching.MethodsWe conducted a 6-month, community-based, randomized, parallel-group trial in a community setting, and allocated into a brief-See or material-based education alone. Pain intensity (NRS, numeric rating scale), functional limitation (RDQ, Roland-Morris disability questionnaire), self-efficacy (PSEQ, pain self-efficacy questionnaire), and quality of life (EQ-5D, European quality of life-5 dimensions) were evaluated at 4, 12, and 24 weeks after the initial consultation.ResultsThe brief-See did not show additional improvement over material-based education on the NRS, but it did on the RDQ, PSEQ, and EQ-5D; the estimated mean group differences in changes from the baseline were -2.1 (-3.5 to -0.7, p = .005) on the RDQ, 6.9 (1.7-12.1, p = .010) on the PSEQ, and 0.07 (0.02-0.12, p = .004) on the EQ-5D.ConclusionThe 100 minutes' education program could be more acceptable, and restores functional limitation, self-efficacy, and quality of life in addition to the effects of material-based education. This has the potential to contribute to the management of CLBP in a community.
