Study information

Study designThis randomised, single-blinded feasibility study used some features adopted from the Single-Subject Research Design (SSRD), with multiple baseline measurements.
Primary study designInterventional
Secondary study designRandomised controlled trial

Scientific titleHead repositioning accuracy and posturography related to cervical facet nerve blockade and spinal manipulative therapy in healthy volunteers: a feasibility study
Study objectivesThree working hypotheses formed the basis for the project:
1. Unilateral facet nerve anaesthesia is expected to elicit disturbed Head Repositioning Accuracy (HRA) and decreased postural control in healthy subjects
2. Disturbed HRA and altered postural control would also be expected after Spinal Manipulative Therapy (SMT) in the cervical spine
3. The disturbances would be caused by abnormal afferent input from the joints
Ethics approval(s)Ethics approval received from:
1. Institutional Review Board of the Scandinavian College of Chiropractic in May 2004 (ref: BL1SKHS)
2. Research Ethical Board of the Swedish Chiropractic Association in May 2007 (ref: BL1KFSFeK)
Health condition(s) or problem(s) studiedNeck proprioception and balance
InterventionAll participants were subjected to unilateral facet nerve blockade (injection of a local anaesthetic) and cervical spinal manipulative chiropractic therapy. There was no control group in this trial. Instead, subjects acted as their own controls by using multiple baseline measurements.
Intervention typeOther
Primary outcome measureCervical proprioceptive functions and static posture were assessed by examining HRA and Computerised Posturography (CPG), respectively.

Sequence of measurements for Group 1:
1. Four baseline measurements
2. One measurement immediately after facet blockade
3. One measurement 24 hours after facet blockade
4. One baseline measurement
5. One measurement immediately after cervical spinal manipulative chiropractic therapy

Sequence of measurements for Group 2:
1. Two baseline measurements
2. One measurement immediately after cervical spinal manipulative chiropractic therapy
3. One baseline measurement
4. One measurement immediately after facet blockade
5. One measurement 24 hours after facet blockade
6. Two baseline measurements
Secondary outcome measuresNo secondary outcome measures
