  Purpose

Comparisons of surgical and non-operative treatment of patients with acute sciatica secondary to lumbar intervertebral disc herniation (AS/LDH) have shown no appreciable difference in outcome. The composition of the non-operative treatment of this patient population remains poorly defined. Spinal manipulative therapy (SMT) has demonstrated value in the treatment of AS/LDH. Recent preliminary studies suggest that SMT provides therapeutic benefit through the modulation of in vivo inflammatory mediators. This feasibility study will define the key experimental variables required to conduct a large multicentre study that will clarify the biological and clinical outcomes of SMT in the treatment of patients with AS/LDH.

Primary Outcome Measures:
  • Rate of recruitment of eligible patients [ Time Frame: The number of patients recruited per week for 19 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Cytokine and cytokine mRNA levels in serum. [ Time Frame: Change from baseline cytokine and cytokine mRNA levels in serum 4 weeks prior to surgery or commencing chiropractic spinal manipulative therapy (CSMT). ] [ Designated as safety issue: No ]
  • Cytokine and cytokine mRNA levels in serum [ Time Frame: Change from baseline cytokine and mRNA levels in serum pre-surgery or following a 4-week course of CSMT. ] [ Designated as safety issue: No ]
  • Cytokine and cytokine mRNA levels in serum [ Time Frame: Change from baseline cytokine and mRNA levels in serum and 12 weeks post-surgery and/or post-CSMT ] [ Designated as safety issue: No ]
  • Cytokine and cytokine mRNA levels in serum. [ Time Frame: Change from baseline cytokine and mRNA levels in serum and 24 weeks post-surgery and/or post-CSMT ] [ Designated as safety issue: No ]
  • Total mRNA levels (isolated from disc tissue and disc / periradicular lavage samples) of interleukins 1,10 and 11, MIP-1 beta TNF alpha, and chemotactic protein alpha. [ Time Frame: Specimens will be harvested an average of 6 weeks post-randomization ] [ Designated as safety issue: No ]
  • Modified Roland Disability Questionnaire (mRDQ) score and Visual Analogue Scale (VAS) pain scale. [ Time Frame: Change from baseline and 4-weeks prior to surgery or commencing 4-weeks of CSMT. ] [ Designated as safety issue: No ]
  • mRDQ and VAS [ Time Frame: Change from baseline and pre-surgery or following a 4-week course of CSMT ] [ Designated as safety issue: No ]
  • mRMQ and VAS [ Time Frame: Change from baseline and 12 weeks post-surgery and/or post-CSMT ] [ Designated as safety issue: No ]
  • mRDQ and VAS [ Time Frame: Change from baseline and 24 weeks post-surgery and/or post-CSMT ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   19 Years to 60 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • chief complaint of sciatica rather than lower back pain
  • pain of up to 6 months' duration
  • a McCulloch criteria score of 5/5 (two clinical symptoms and two clinical signs of sciatica, and diagnostic imaging confirming the presence of a herniated nucleus pulposus contacting a spinal nerve root at the appropriate level)
  • fluency in spoken and written English to ensure subjects understand the content of questionnaires and consent

Exclusion Criteria:

  • progressive neurological deficit
  • spinal fracture
  • spinal tumor
  • spinal infection
  • spinal nerve root motor score of less than 4/5
  • spinal stenosis that is not attributable to a herniated disc
  • any other significant spinal ailment or local or generalized co-morbidity ailment that could affect outcomes independently of SMT ( e.g. seronegative spondyloarthropathy, malignancy).
