Evaluation of Specific Stabilising Excercise in the Treatment of Chronic Low Back Pain with Radiologic Diagnosis of Spondylolysis or Spondylolitstheses
Spine (1997) 22(24): 2959-2967; P. O'Sullivan, L. Twomey and G. AllisonStudy Design
A randomised controlled trial,test-retest design with a 3, 6, and 30 month postal questionnaire follow up.
Objective
To determine the efficacy of a specific exercise intervention in the treatment of patients with chronic low back pain and radiologic diagnosis of spondylolysis or spondylolisthesis surrounding the spine (deep abdominal muscles and lumbar multifidus), considered to provide dynamic stability and fine control to the lumbar spine. In no study have researchers evaluated efficacy of this intervention in a population with chronic low back pain where the anatomic stability of the spine was compromised.
Methods
Forty-four patients with this condition were assigned randomly to two treatment groups. The first group underwent a 10-week specific exercise treatment program involving the specific training of the deep abdominal muscles, with co-activation of the lumbar multifidus proximal to the pars defects. The activation of these muscles was incorporated into previously aggravating static postures and functional tasks.
Results
After intervention the specific exercise group showed a statistically significant reduction in pain intensity and functional disability levels, which was maintained at a 30-month follow-up. The control group showed not significant change in these parameters after intervention or at follow-up.
Summary
A "specific exercise" treatment approach appears more effective than other commonly prescribed conservative treatment programs in patients with chronically symptomatic spondylolysis or spondylolisthesis :
- Spondylolysis - a structural defect in posterior arch of the spinal column on one or both sides.
- Spondylolisthesis - a forward slip of one vertebral segment upon another, usually as a result of bilateral spondylolysis.
