Study type
Interventional
Description of intervention(s) / exposure
Multimodal chiropractic treatment provided by a chiropractor, of at least 3 years' clinical experience, comprising of any combination of the following: lumbar and thoracic manipulation (such as diversified or Thompson drop-piece maneuvers), mobilization, massage, application of heat to the spine and prescription of stretching or strengthening (isometric and/or isotonic) exercise to be performed at home. The exact choice of chiropractic treatment combination as well as the intensity and duration of any exercises that may be prescribed will depend on the clinical judgement of the chiropractic clinician. Treatment will take 4 weeks of three sessions per week. The above chiropractic treatment will be provided PLUS Podiatric treatment comprising of: custom-made orthotic treatment, as fabricated and fitted by a qualified podiatrist for 4 weeks. (briefly, a mould will be made of both of the participants' feet and used to construct custom-made orthoses to be worn as insoles). The participants will be instructed to use the orthoses in every pair of shoes that they wear during the day (with the exception of flip-flops). The podiatric treatment will be provided by a podiatrist of at least 3 years' clinical experience. Treatments will be administered one-on-one at the chiropractic or the podiatric clinic. Those receiving the combined chiropractic and podiatric treatment will be asked at every chiropractic visit to report for how many days they had worn the orthotics in the previous week.

Eligibility
Key inclusion criteria
Non-specific low back pain of at least three-months duration; Unilateral foot hyperpronation of +6 score on Foot Posture Index (FPI); and dorsiflexion of the ipsilateral ankle of less than 10 degrees. Radiographic examination of the relative heights of the femoral heads at baseline in standard lumbopelvic views will need to demonstrate that the shorter leg is ipsilateral to the hyper-pronated foot.
Minimum age
18 Years
Maximum age
65 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
specific pathologies that may cause back pain such as internal organ disease, active inflammatory spondylo-arthropathies osteomyelitis and spinal tumours; recent spinal trauma or surgery; detection of a shorter leg contralateral to unilateral foot hyperpronation; lumbar spinal manipulation in the previous six months; radicular leg pain; diagnosed foot pathology (other than functional hyper-pronation) including trauma structural deformities or +6 score (or above) on FPI in both feet; and any previous fitting or use of orthotics.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group allocations will be concealed from investigators by placing them in opaque, consecutively numbered sealed envelopes. Once participants are determined eligible to participate, the treating clinician will open the envelope and commence treatment according to group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants at each site will be randomised using a computer-generated permuted block randomization protocol (blocks of four) to either the single or combined treatment group (i.e. Group A or B).

Efficacy
Statistical methods / analysis
Descriptive statistics (frequencies and proportions or means and standard deviations [SDs]) will be used for demographic variables (i.e. age, sex, other musculoskeletal pain, and comorbidities), chronicity of low back pain, and treatment satisfaction. Means and 95% confidence intervals (CIs) will be calculated for RMQD and NRS-11 scores pre- and post-treatment, and for pre/post treatment differences. As this study is not sufficiently statistically powered to investigate treatment efficacy or effectiveness, formal tests of statistical significance will not be conducted. However, any clinically meaningful group differences will be reported. All data analysis will be done using GraphPad Prism 7 for Windows.
