Description of intervention(s) / exposure
Manual therapy:

Participants will receive 4 (once a week) 30 minute sessions of manual therapy including the following techniques which will be applied at the discretion of the physiotherapists .
- Grade II-III segmental postero-anterior and/or antero-posterior mobilisations following the movement plane of the cervical zygapophyseal joints (downslope or upslope). These will be applied to pain reproducing and adjacent cervical segments.

Comparator / control treatment
Specific neck exercise:

Participants will undertake a programme of neck specific exercises. The programme will involve 4 physiotherapist-led sessions (once a week) and daily home exercises for 4 weeks (approximately 20 minutes/day). The full exercise programme is as follows:

A) Neck Flexor Training:

Block 1. Re-education of CCF movement pattern

Block 2. Holding capacity

Block 3. Interaction between the deep/superficial cervical flexors

Block 4. Co-contraction of the deep cervical flexors/extensors

Block 5. Strength/endurance of the cervical flexors


B) Neck Extensor Training

Block 1. Re-education of extension movement pattern

Block 2. Co-contraction of the deep cervical flexors/extensors

Block 3. Strength/endurance of the cervical extensors

Adherence will be monitored by asking participants to submit a completed sheet that outlines the days when they have performed the provided exercise programme.

Patient specific functional scale: this is a patient identified self-report questionnaire that measures general activity limitations. The scale ranges from 0 (unable to perform) to 10 (able to perform the activity at the level prior to injury). The patient reports three activities and rates each activity from 0 to 10 which are averaged for a composite score.

Participants will be asked if treatment has met their expectations with the following question: “How would you describe how you feel now compared to what you expected?”; participants will have to chose from the following responses:
- “I have more pain than I expected”
- “I have less pain than I expected”
- “I have the amount of pain I expected”
Timepoint [10] 381120 0

Secondary outcome [11] 381121 0
Pressure pain threshold (PPT) will be measured:
1. Bilaterally over the upper trapezius muscle and C5-6 joints in the cervical spine
2. Over the most painful point in the neck as described by the patient
PPT will be measured with a handheld algometer of 1 cm diameter and will be defined as the minimum pressure where pressure sensation becomes painful. Three measures will be taken at each site and the average of the three calculated to represent PPT at each site.
Timepoint [11] 381121 0
Baseline and immediately after the first treatment session.

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 treating therapist will open an opaque sealed envelope (one for each participant) which has been prepared in advance by a third party and contains the treatment allocation
of that participant
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table.
Masking / blinding

Statistical methods / analysis
It is anticipated that approximately 80 subjects will be required. Once data collection is completed, a quantitative analysis will be performed. The effectiveness of the treatments will be analysed in relation to the recorded primary and secondary outcome measures,

Furthermore, the predictive value of baseline measures on treatment outcome will be established.. In addition to the baseline measures described previously in 'step 4: outcome measures', the following measures will be taken in order to test their predictive value with regards to treatment effectiveness:

1: If pain follows a compression (e,.g. aggravated by extension, ipsilateral rotation and ipsilateral side flexion of the neck) or stretch (flexion, contralateral rotation and contralateral side flexion of the neck) pattern
2. Test of movement pattern of neck flexion
3. Test of movement pattern of neck extension
4. Test of the subocciptal muscles
5. Presence of hypomobility and pain during passive manual testing of the cervical spine
6. Number of physiotherapy or osteopathy treatment sessions in the last 12 months
