Validation of a Novel Sham Cervical Spinal Manipulation Procedure
Ho1: In chronic neck pain patients, randomly treated with either a "sham" or "real" cervical manipulation procedure, the probability of perceiving a Real Manipulation Procedure is equal to the probability of obtaining a Real Manipulation Procedure, AND, Ho2: Spinal tenderness will remain unchanged following the treatment procedure for both groups.
Secondary (null) hypotheses:
- Neck pain, cervical ranges of motion and paraspinal EMG responses to pressure pain will remain unchanged in both groups;
- there will be no differences between groups with respect to 2a) neck joint cavitations and 2b) forces across the cervical spine measured during the manoeuvres.
Chronic Neck Pain
|Official Title:||Validation of a Novel Sham Cervical Spinal Manipulation Procedure.|
- The perception by subjects as to whether they received a real treatment (YES/NO) [ Time Frame: 10 mins ]
- Change scores of the pressure algometry [ Time Frame: 10 mins ]
- Current Neck Pain, Ranges of Motion, MES Response will be analysed by comparing baseline, 15-and 120-minute score [ Time Frame: approximately 1 hours + ]

|Primary Completion Date:||October 2010 (Final data collection date for primary outcome measure)|
- Develop a randomized controlled clinical trial design to optimize the testing of the effects of a sham vs real cervical manipulation.
- Use novel modifications of both a sham a real manipulation to create "procedures" designed to optimize group equivalence in the RCT design. Then, evaluate the accuracy of 'patient post-treatment perception of treatment type' versus actual administered treatment (primary outcome #1).
- Quantitatively evaluate group differences in local soft-tissue tenderness by algometry (primary outcome #2), as well as changes in self-reported neck pain, ranges of motion, myoelectric responses in selected neck muscles and forces imparted during the procedures.
- Evaluate the occurrence of neck joint cavitation during the manoeuvres comprising these procedures.
