Short- or Long-Term Treatment of Spinal Disability in Older Adults With Manipulation and Exercise

Abstract

Objective: Back and neck pain are associated with disability and loss of independence in older adults. Whether long-term management using commonly recommended treatments is superior to shorter-term treatment is unknown. This randomized clinical trial compared short-term treatment (12 weeks) versus long-term management (36 weeks) of back- and neck-related disability in older adults using spinal manipulative therapy (SMT) combined with supervised rehabilitative exercises (SRE).

Methods: Eligible participants were ages ≥65 years with back and neck disability for ≥12 weeks. Coprimary outcomes were changes in Oswestry Disability Index (ODI) and Neck Disability Index (NDI) scores after 36 weeks. An intent-to-treat approach used linear mixed-model analysis to detect between-group differences. Secondary analyses included other self-reported outcomes, adverse events, and objective functional measures.

Results: A total of 182 participants were randomized. The short-term and long-term groups demonstrated significant improvements in back disability (ODI score -3.9 [95% confidence interval (95% CI) -5.8, -2.0] versus ODI score -6.3 [95% CI -8.2, -4.4]) and neck disability (NDI score -7.3 [95% CI -9.1, -5.5] versus NDI score -9.0 [95% CI -10.8, -7.2]) after 36 weeks, with no difference between groups (back ODI score 2.4 [95% CI -0.3, 5.1]; neck NDI score 1.7 [95% CI 0.8, 4.2]). The long-term management group experienced greater improvement in neck pain at week 36, in self-efficacy at weeks 36 and 52, and in functional ability, and balance.

Conclusion: For older adults with chronic back and neck disability, extending management with SMT and SRE from 12 to 36 weeks did not result in any additional important reduction in disability.
