A multivariate time-series descriptive case study of chiropractic care in the treatment of cervical pain

This paper presents a multivariate quantitative description of the temporal course of 13 clinical variables measured before, during and after a multimodal chiropractic treatment package. Clinical measures included total and peak daily cervical pain, unleveling of the pelvis, shoulders and cranium; bilateral grip strength; and cervical ranges of motion. Intervention techniques included heel wedges; cervical, abdominal, and foot exercises; and spinal adjustments (cervical spine and ilium). Data are presented in tabular and graphic formats, and limitations in validity and reliability are reviewed. Interpretive limitations included confounding by multiple and sequential interventions and by lack of experimental control comparisons. However, the study suggests the plausible influence of biomechanical and adjustive care upon mediators and clinical outcomes. Strengths inherent in multivariate time-series research are noted.
