COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Side posture spinal manipulation commonly referred to as a hypothenar transverse push procedure will be applied unilaterally to the L5 region of ther lumbar spine. The manipulation will be provided by an experienced chiropractor with 15 years of clinical experience. The duration of the procedure is approximately 1 minute and will be performed once.
Intervention code [1] 289642 0
Treatment: Other
Comparator / control treatment
Comparing the effect of lumbar spinal manipulation when applied to either the left or right hand side of the spine. One group will receive the manipulation on the right (group 1) and one group will receive the manipulation on the left (group 2).
Control group
Active

Outcomes
Primary outcome [1] 292438 0

Immediately, 10 minutes, 20 minutes and 30 minutes after administration of intervention
Primary outcome [2] 292490 0
Pressure pain thresholds will be measured using a Wagner pressure algometer 2cm lateral to the L5 spinous process bilaterally.
Timepoint [2] 292490 0
Immediately, 10 minutes, 20 minutes and 30 minutes after administration of intervention
Primary outcome [3] 292491 0

Secondary outcome [1] 308945 0
Pinprick sensitivity will be determined using the Neuropen whereby a constant 40g pressure is applied to the skin and the participant rates their perceived sharpness on an 11 point numerical pain rating scale 2cm inferior and lateral to the root of the spine of the scapula, over the belly of the infraspinatus muscle bilaterally.

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 group assignment will be placed in sequentially numbered, opaque, sealed, envelopes. The researcher who will apply the intervention, will use these envelopes to allocate participants to their respective groups.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Upon meeting the criteria outlined in section, participants will be randomly assigned to a group. Using a random number generator a randomisation list consisting of equal numbers of 1s and 2s representing the group allocation will be created by a researcher not taking outcomes measures or applying the intervention. The group assignment will be placed in sequentially numbered, opaque, sealed, envelopes. The researcher who will apply the intervention, will use these envelopes to allocate participants to their respective groups. Group 1 will receive the intervention on the right, while group 2 will receive the intervention on the left.

Summary
Brief summary
The aim of the study is to investigate whether manipulation of the lumbar spine effects measures of deep and superficial pain intensity at local and remote locations, for up to 30 minutes post manipulation. We also aim to investigate whether, if differences exist, these changes follow a segmental or non-segmental pattern, and whether the side to which spinal manipulation (SM) is applied creates asymmetrical changes in pain intensity.
