RESUMO
Objective: The purpose of this article is to describe a protocol to examine the feasibility of combining podiatric orthotic treatment with multimodal chiropractic treatment to treat chronic low back pain (CLBP) in those with a functional short leg on the same side as a unilateral pronated foot. Methods: This is a protocol for a multicenter feasibility 2-arm parallel randomized controlled trial. One hundred and thirty-two adults with CLBP and a functional short leg on the same side as a unilateral pronated foot are to be recruited in Melbourne, Australia, and Madrid and Seville, Spain. Forty-four participants at each site are to be randomized to multimodal chiropractic treatment including spinal manipulation or to multimodal chiropractic treatment also involving spinal manipulation, together with podiatric custom-made orthoses. Chiropractic visits are to comprise 12 treatments over 4 weeks. Outcome measures will be recruitment, compliance, costs, CLBP-related disability, and perceived low back pain. Results: Feasibility results will be reported in text format and the clinical data reported using descriptive statistics focusing on any clinically significant results. Conclusion: This protocol describes a feasibility study for assessing the combination of podiatric orthotic treatment with multimodal chiropractic treatment to treat CLBP in those with a functional short leg on the same side as a unilateral pronated foot.
