Validation of a Novel Sham Cervical Spinal Manipulation Procedure

This study has been completed.

Canadian Memorial Chiropractic College Identifier:
First received: September 15, 2009
Last updated: November 16, 2010
Last verified: November 2010

Primary hypotheses:

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:

  1. Neck pain, cervical ranges of motion and paraspinal EMG responses to pressure pain will remain unchanged in both groups;
  2. 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.

Primary Outcome Measures:
  • 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 ]

Secondary Outcome Measures:
  • Current Neck Pain, Ranges of Motion, MES Response will be analysed by comparing baseline, 15-and 120-minute score [ Time Frame: approximately 1 hours + ]

Estimated Enrollment: 80
Study Start Date: February 2009
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Detailed Description:
  1. Develop a randomized controlled clinical trial design to optimize the testing of the effects of a sham vs real cervical manipulation.
  2. 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).
  3. 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.
  4. Evaluate the occurrence of neck joint cavitation during the manoeuvres comprising these procedures.
