Chiropractic Management of Low Back Pain: A Retrospective Case Series of Eight Patients

Abstract

Background: Low back pain (LBP) is a leading cause of disability worldwide, for which many individuals seek non-pharmacological treatments such as chiropractic care. This article examines outcomes for a series of patients with LBP treated at a private chiropractic clinic. Methods: A retrospective case series was conducted by reviewing the files of eight patients presenting with low back pain at Back To Health Chiropractic in Zeeland, MI. Data on chief complaint, baseline pain and function, and post-treatment outcomes were collected. The primary outcome measure was the patient-reported percentage of pain reduction. Results: The cohort of eight patients reported a mean pain reduction of 90% (median 93%). All patients reported a return to normal activities. Outcomes were achieved over time frames ranging from 6 weeks to 3 months. Treatments included chiropractic adjustments, spinal decompression, class IV laser therapy, and SoftWave therapy. Conclusion: The findings from this case series suggest that a multimodal approach to chiropractic care can be associated with substantial reductions in pain and improvements in function for patients with low back pain. The results are promising, but due to the study's limitations, including the lack of a control group, further research is required to establish causality.

Methods

This study employed a retrospective case-series design to evaluate the outcomes of patients treated for low back pain at a single chiropractic center. The records were sourced from Back To Health Chiropractic, a multi-provider practice located in Zeeland, MI. Patient files were eligible for inclusion if the primary presenting complaint was low back pain and if pre-treatment and post-treatment outcome data were documented in the clinical records. A total of eight de-identified patient cases meeting these criteria were selected for this review.

For each case, data were extracted regarding the patient's chief complaint, baseline functional limitations, and initial pain severity, which was often described using a numeric rating scale (NRS) or qualitative descriptors (e.g., 'constant ache'). The primary outcome measure was the percentage of pain reduction as reported at the conclusion of the principal phase of care. This metric was documented in the patient files. The timeframe of care and the specific treatment protocols utilized were also noted. Interventions applied were varied and tailored to the individual patient but were drawn from the clinic's available techniques, which include chiropractic adjustments, spinal decompression, Class IV laser therapy, SoftWave therapy, and corrective exercises. Mobility improvement was consistently noted anecdotally as a return to normal activities, but a quantitative percentage of improvement was not systematically tracked and therefore not included in the aggregate analysis. No control group was used in this study.

Discussion

The results of this case series suggest that a multimodal chiropractic treatment approach may be highly effective in reducing pain and restoring function in patients with various presentations of low back pain. The reported mean pain reduction of 90% across the eight cases is a substantial clinical improvement, indicating that the care provided had a profound positive impact on these individuals' quality of life. The fact that all patients returned to normal activities further underscores the functional benefits of the treatment.

The interventions used—including chiropractic adjustments, spinal decompression, laser therapy, and SoftWave therapy—target different aspects of musculoskeletal pathology, such as joint restriction, inflammation, and soft tissue dysfunction. The positive outcomes observed may be attributable to this synergistic, multimodal approach that addresses the patient's condition from multiple angles. For instance, combining spinal adjustments to restore joint mechanics with laser therapy to reduce inflammation may produce a better outcome than either modality alone.

The findings are consistent with a broader body of evidence supporting chiropractic care for low back pain, but the magnitude of the reported pain reduction in this series is notably high. While this may reflect the efficacy of the specific protocols used at this clinic, it must be interpreted with caution. Without a control group, it is not possible to determine what proportion of the improvement is due to the specific interventions, the placebo effect, the natural history of the condition, or other confounding factors. Nonetheless, the consistency of positive outcomes across this small but diverse group of patients provides a clinical rationale for considering such multimodal chiropractic strategies for individuals suffering from significant low back pain.

Limitations

This study has several important limitations inherent to its design. As a retrospective case series, it is susceptible to selection bias, as the cases reviewed may not be representative of all patients with low back pain treated at the clinic. The lack of a control group makes it impossible to attribute the observed outcomes directly to the chiropractic interventions; factors such as natural history, regression to the mean, and the placebo effect cannot be ruled out. All outcome measures, particularly pain reduction, were based on patient self-report, which is subjective and can be influenced by patient expectations. Furthermore, the study was conducted at a single private practice, which may limit the generalizability of the findings to other clinical settings or patient populations. Mobility, a key functional outcome, was not measured with a standardized instrument, relying instead on qualitative reports of returning to normal activities. Future prospective, controlled studies are needed to confirm these preliminary findings.
