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.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Dose Optimisation for Spinal treatment Effectiveness (The DOSE Study): A randomised controlled pilot trial investigating the effects of high and low mobilisation forces in patients with neck pain
Scientific title
In patients with chornic non-specific neck pain, is a high force mobilisation better than a low force mobilisation or laser for immediate improvement in pressure pain threshold scores?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. High force mobilisation will consist of a single application of 3 sets of 30 seconds of oscillating pressures manually applied by thhe physiotherapist' thumbs with a mean peak force of 90N to the symptomatic spinal level. 2. Low force mobilisation will consist of a single application of 3 sets of 30 seconds of oscillating pressures manually applied by thhe physiotherapist' thumbs with a mean peak force of 30N to the symptomatic spinal level. 3. Laser will consist of a single application of 3 sets of 30 seconds application applied using the Echolac with probe to skin contact over the symptomatic level. Laser was detuned (i.e., not active) and represented the placebo group, or an inactive treatment control.

Comparator / control treatment
treatment: 1. High force mobilisation will consist of a single application of 3 sets of 30 seconds of oscillating pressures manually applied by thhe physiotherapist' thumbs with a mean peak force of 90N to the symptomatic spinal level. 2. Low force mobilisation will consist of a single application of 3 sets of 30 seconds of oscillating pressures manually applied by thhe physiotherapist' thumbs with a mean peak force of 30N to the symptomatic spinal level. 3. Laser will consist of a single application of 3 sets of 30 seconds application applied using the Echolac with probe to skin contact over the symptomatic level. Laser was deactivated and therefore was the placebo control group.

Outcomes
Primary outcome [1] 262388 0
Pressure pain threshold (PPT) will be measured with the J-tech algometer (Tracker Freedom Algometry, J-tech Medical (http://jtechmedical.net/products/pain_eval/freedom/freedom_algometry.cfm) over the following landmarks in randomised order: (1) Adjacent to the spinous process at the treated spinal level (right side) (2) Right upper trapezius muscle (3) Right median nerve trunk at the elbow. Measurements will be taken in triplicate and averaged for each landmark.
Timepoint [1] 262388 0
Immediately before treatment application, immediately after treatment application and one follow-up 3-5 days later
Secondary outcome [1] 273681 0
Cervical range of motion will be measured with a Cervical Range of Motion instrument (CROM, Performance Attainment Associates, Minnesota, USA, http://www.spineproducts.com/) in the following ranges: (1)Total sagittal plane ROM, (2) Total horizontal plane ROM and (3) Position (degrees) at first onset or increase in pain with movement towards the most painful movement direction. Measurements will be taken in triplicate and averaged.
Timepoint [1] 273681 0
Immediately before treatment application, immediately after treatment application and one follow-up 3-5 days later
Secondary outcome [2] 273682 0
Cervical spine stiffness will be measured with a customised device that applied 5 standardised oscillating pressures to the spinous process using a probe while recording the resistance to movement and the distance the probe travels. The relationship between resistance and displacement (distance) represents the spinal stiffness (N/mm). The symptomatic spinal level as well as C7 (for normalisation)will be measured.

Secondary outcome [3] 273683 0
Patient reported pain (visual analogue scale)

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be screened for contraindicated conditions prior to enrolling in the study. Patients will be assigned to treatment groups through random allocation using opaque envelopes, opened on the day of data collection affter initial measurements are taken. The researcher doing the recruiting will have no knowledge of the treattment group of potential participants.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomised number sequence is generated through a computer program available online.
Masking / blinding
Blinded (masking used)
