PubMed, Scopus, and Web of Science were searched from inception to June 30, 2026, with Google Scholar used as a supplementary source. Randomized controlled and quasi-experimental studies investigating interventions incorporating the NASM corrective exercise continuum in individuals with MSPS were eligible. Standardized mean differences (SMD) with 95% confidence intervals (CIs) were pooled using a random-effects model.<br> <strong>Results</strong>: Twelve studies (n=382) were included in the quantitative synthesis. Overall, interventions incorporating the NASM corrective exercise continuum reduced pain compared with control interventions (SMD=1.057, 95% CI, 0.794%, 1.319%; P<0.001). Considerable heterogeneity was observed (I&sup2;=75%). Subgroup analyses demonstrated significant pain reduction for neck pain (SMD=0.904, 95% CI, 0.586%, 1.221%; P<0.001) and shoulder pain (SMD=1.311, 95% CI, 0.689%, 1.933%; P<0.001), whereas no significant effect was identified for back pain (SMD=0.691, 95% CI, &minus;0.621%, 2.003%; P=0.302). The included studies were generally of moderate-to-high methodological quality, and Egger&rsquo;s regression test indicated no evidence of significant publication bias (P=0.42).<br> <strong>Discussion</strong>: Interventions incorporating the NASM corrective exercise continuum appear to be an effective conservative intervention for reducing pain in individuals with MSPS, particularly those with neck and shoulder disorders. Further high-quality randomized controlled trials with standardized intervention protocols and longer follow-up periods are warranted to establish long-term effectiveness and identify patient populations most likely to benefit.</div> National Academy of Sports Medicine (NASM), Corrective exercise, Pain, Meta-analysis 259 272 http://irj.uswr.ac.ir/browse.php?a_code=A-10-753-4&slc_lang=en&sid=1 Rahman Sheikhhoseini Rahman.pt82@gmail.com 0000-0002-9885-3591 Yes Department of Sport Injuries and Corrective Exercises, Faculty of Physical Education and Sport Science, Allameh Tabataba’i University, Tehran, Iran.
