Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
On a single occasion, each participant will be randomised to receive one of the following two interventions:
A) a single cervical high-velocity low-amplitude spinal manipulation technique known as the index pillar push, targeted at the C5-C6 facet joint on the most symptomatic side.
B) a single lumbar high-velocity low-amplitude spinal manipulation technique known as the hypothenar mamillary push, targeted at the L5-S1 facet joint on the most symptomatic side.
Each intervention will take approximately 1 minute to complete. Interventions will be performed in a private research room, on a chiropractic examination table, by a chiropractor with a minimum of 3 years clinical experience.
Multiple registered chiropractors will provide the interventions. They will receive training to standardise the techniques and participant interaction. Training will be in the form of a single 30 minute small group workshop. Topics will include a refresher on the specific manipulation techniques being used (the chiropractors will already be at least well familiar with the techniques), how to interact with participants in a reassuring but neutral manner. This will be run by a researcher with clinical experience as a chiropractor.

Outcomes
Primary outcome [1] 299250 0
Pressure pain threshold will be measured using a digital pressure algometer with a 1cm2 rubber probe (Wagner FPIX 50, USA), bilaterally at the medial gastrocnemius muscle, L5 paraspinal musculature, deltoid muscle, and C5 paraspinal musculature.
Timepoint [1] 299250 0
Pressure pain threshold will be measured at each site immediately following intervention, and again 15 minutes, 30 minutes, 45 minutes, and 60 minutes after intervention.
Secondary outcome [1] 326684 0
None

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)
The clinician providing the intervention will randomise the participant to one of two groups with the use of sequentially numbered, sealed, opaque envelopes containing randomised ones or twos. Group one will receive a cervical spinal manipulation and group two will receive a lumbar spinal manipulation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The ones and twos will be generated and placed into the sequential envelopes using an online random number generator with 1:1 allocation, by a researcher not involved in data collection (http://www.graphpad.com/quickcalcs/).
Masking / blinding
Blinded (masking used)

Efficacy
Statistical methods / analysis
Based on the study by Waller et al. 2015, to see a 15% change (effect size 0.64) in pressure pain threshold at the lumbar spine, based on 80% power and with alpha at 5%, a sample size of 40 per group (80 total) will be required.
Repeated measures ANCOVAs will be run with factors of time and group to investigate within- and between-group change. Covariates for the ANCOVA will include two psychosocial questionnaires.
