Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1: Stretching & MAM
Group 2: Stretching & IAM
Group 3: Stretching

Group one (standard care): a series of active cervical range of motion stretches held for 30sec, repeated 3 times in six different directions for a total of 5 minutes in addition to one high-velocity, low-amplitude manually applied manipulation (MAM) administered on a single occasion to the cervical spine.

Group two (comparison intervention): stretching routine as described above in addition to one instrument applied manipulation (IAM) administered on a single occasion to the cervical spine. IAM will be delivered using an Activator IV instrument which delivers a measurable force to the desired target (in this instance the lower cervical spine).

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)
Once the volunteer has successfully completed the screening procedure, provided a medical history and satisfied the inclusion criteria they will be enrolled as a participant in the trial. A participant will then receive a trial specific identification number and be randomly allocated to one of the three trial groups.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be generated using a computer generated randomisation sequence provided by an administrative officer in the Department of Chiropractic. That person will have no other involvement in the trial.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

The people administering the treatment/s
The people assessing the outcomes
Intervention assignment
Parallel
Other design features
Single-blinded, randomised controlled clinical trial.
Phase
Not Applicable
Type of endpoint/s
Efficacy
Statistical methods / analysis
Calculation of sample size was based on the following: detecting a difference of 0.4 units in pressure pain threshold levels, a standard deviation of 0.4, comparison of 2 means, an alpha of 0.05, and a desired power (beta) of 80%. These assumptions generated a sample size of 21 participants per group.

Data analysis will include application of the T-test to compare between the interventions.
