Background: Low back pain (LBP) is a common disabling condition in older adults which often limits physical function and diminishes quality of life. Two clinical trials in older adults have shown spinal manipulative therapy (SMT) results in similar or small improvements relative to medical care; however, the effectiveness of adding SMT or rehabilitative exercise to home exercise is unclear. 

Methods: We conducted a randomized clinical trial assessing the comparative effectiveness of adding SMT or supervised rehabilitative exercise to home exercise in adults 65 or older with sub-acute or chronic LBP. Treatments were provided over 12-weeks and self-report outcomes were collected at 4, 12, 26, and 52 weeks. The primary outcome was pain severity. Secondary outcomes included back disability, health status, medication use, satisfaction with care, and global improvement. Linear mixed models were used to analyze outcomes. The primary analysis included longitudinal outcomes in the short (week 4–12) and long-term (week 4–52). An omnibus test assessing differences across all groups over the year was used to control for multiplicity. Secondary analyses included outcomes at each time point and responder analyses. This study was funded by the US Department of Health and Human Services, Health Resources and Services Administration. 

Results: 241 participants were randomized and 230 (95%) provided complete primary outcome data. The primary analysis showed group differences in pain over the one-year were small and not statistically significant. Pain severity was reduced by 30 to 40% after treatment in all 3 groups with the largest difference (eight percentage points) favoring SMT and home exercise over home exercise alone. Group differences at other time points ranged from 0 to 6 percentage points with no consistent pattern favoring one treatment. One-year post-treatment pain reductions diminished in all three groups. Secondary self-report outcomes followed a similar pattern with no important group differences, except satisfaction with care, where the two combination groups were consistently superior to home exercise alone. 

Conclusions: Adding spinal manipulation or supervised rehabilitative exercise to home exercise alone does not appear to improve pain or disability in the short- or long-term for older adults with chronic low back pain but did enhance satisfaction with care.

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.

Spinal manipulative therapy (SMT) and exercise have demonstrated effectiveness for neck pain (NP). Adverse events (AE) reporting in trials, particularly among elderly participants, is inconsistent and challenges informed clinical decision making.

This paper provides a detailed report of AE experienced by elderly participants in a randomized comparative effectiveness trial of SMT and exercise for chronic NP.

AE data, consistent with CONSORT recommendations, were collected on elderly participants who received 12 weeks of SMT with home exercise, supervised plus home exercise, or home exercise alone. Standardized questions were asked at each treatment; participants were additionally encouraged to report AE as they occurred. Qualitative interviews documented participants' experiences with AE. Descriptive statistics and content analysis were used to categorize and report these data.

Compliance was high among the 241 randomized participants. Non-serious AE were reported by 130/194 participants. AE were reported by three times as many participants in supervised plus home exercise, and nearly twice as many as in SMT with home exercise, as in home exercise alone. The majority of AE were musculoskeletal in nature; several participants associated AE with specific exercises. One incapacitating AE occurred when a participant fell during supervised exercise session and fractured their arm. One serious adverse event of unknown relationship occurred to an individual who died from an aneurysm while at home. Eight serious, non-related AE also occurred.

Musculoskeletal AE were common among elderly participants receiving SMT and exercise interventions for NP. As such, they should be expected and discussed when developing care plans.

Objective: To explore perceptions of spinal manipulative therapy and exercise among adults aged 65 years and older with chronic neck pain.

Design: Mixed methods study embedded within a randomized clinical trial.

Subjects/Patients: Interviews were conducted with 222 of 241 randomized clinical trial participants. They had a mean age of 72. 2 years and they had neck pain of moderate severity and of 6 years mean duration.
Methods: Semi-structured interviews were conducted at the completion of the 12 week intervention phase, during which participants received spinal manipulative therapy and exercise interventions. Interviews explored determinants of satisfaction with care, whether or not therapy was worthwhile, and what was liked and disliked about treatment. Interviews were recorded and transcribed; content analysis was used to identify themes within responses.

Results: Participants placed high value on their relationships with health care team members, supervision, individualized care, and the exercises and information provided as treatment. Change in symptoms did not figure as prominently as social and process-related themes. Perceptions of age, activities, and co-morbidities influenced some seniors’ expectations of treatment results, and comorbidities impacted perceptions of their ability to participate in active care.

Conclusion: Relationship dynamics should be leveraged in clinical encounters to enhance patient satisfaction and perceived value of care.

Global Perceived Effect (GPE) is a commonly used outcome measure for musculoskeletal conditions like neck pain; however, little is known regarding the factors patients take into account when determining their GPE. The overall objective of this work was to describe the thematic variables, which comprise the GPE from the patient's perspective.

The NCCAM-funded R25 project has provided the impetus for meaningful culture change at Northwestern Health Sciences University (NWHSU) which, over the long term, can affect the professional culture of our CAM constituents. Benefiting from a unique collaboration with the University of Minnesota Center for Spirituality and Healing, we are making substantial progress in developing our CAM professionals' research-related skill sets so that they may truly learn and practice in evidence informed ways.

Neck pain is a common global health care complaint with considerable social and economic impact. Systematic reviews have found exercise therapy (ET) to be effective for neck pain, either alone or in combination with spinal manipulation. However, it is unclear to what extent spinal manipulation adds to supervised exercise or how supervised high-dose exercise compares with low-dose home exercise.

The overall objective of our educational program is to facilitate evidence informed practice (EIP) among CAM practitioners. Through the practice of EIP, we aim to educate research-literate Content on integrative healthcare and complementary and alternative medicine is being taught in hundreds of educational programs across the country. Nursing, medical, osteopathic, chiropractic, acupuncture, naturopathic, and other programs are finding creative and innovative ways to include these approaches in new models of education and practice. 

The purpose of this study was to assess the relative efficacy of supervised exercise, spinal manipulation, and home exercise for the treatment of CLBP.  A total of 301 individuals were included in this trial. For all three treatment groups, outcomes improved during the 12 weeks of treatment. Those who received supervised trunk exercise were most satisfied with care and experienced the greatest gains in trunk muscle endurance and strength, but they did not significantly differ from those receiving chiropractic spinal manipulation or home exercise in terms of pain and other patient-rated individual outcomes, in both the short- and long-term.  For CLBP, supervised exercise was significantly better than chiropractic spinal manipulation and home exercise in terms of satisfaction with treatment and trunk muscle endurance and strength. Although the short- and long-term differences between groups in patient-rated pain, disability, improvement, general health status, and medication use consistently favored the supervised exercise group, the differences were relatively small and not statistically significant for these individual outcomes.
