Abstract
BACKGROUND: Low back pain (LBP) is a global musculoskeletal ailment. Over the past few years, dry needling (DN) has garnered interest from both physical therapists and patients. Physical therapy commonly employs spinal manipulation to alleviate persistent LBP and other musculoskeletal disorders. The aim of this study was to investigate the effects of spinal manipulation alone and in combination with DN on functional disability and endurance in individuals suffering from chronic nonspecific LBP. METHODS: Patients of both genders who had chronic nonspecific LBP and who had not received physical therapy within the last 3 months were included in this single-blind, randomized controlled trial using purposive sampling. All participants were randomly assigned to either the experimental (SMT + DN) or control (SMT alone) group using computer-generated random numbers. The data were analyzed using the Statistical Package for Social Sciences (SPSS) version 23.0. For between-group comparisons, the Mann-Whitney U test was used. A P-value < .05 was considered to indicate statistical significance. RESULTS: The analysis of the difference between the 2 groups revealed that the mean ± standard deviation (SD) for the SMT alone group was 16.09 ± 3.963 at baseline and 12.66 ± 3.801 at 8 weeks, whereas for the DN + ST group, it was 13.67 ± 3.904 at baseline and 10.92 ± 3.534 at 8 weeks, with a P-value of .003. Thus, the RMDQ score improved gradually in both groups, and the mean endurance score reported for the ST group was 2.5 to 4.5, while that reported for the DN + ST group was 3.1 to 5.1. CONCLUSION: The results of this study showed that both therapies effectively reduced LBP. When comparing the effects of spinal manipulation alone to those of spinal manipulation combined with DN, the latter showed significantly greater benefits.
