Spinal manipulation, epidural injections, and self-care for sciatica: a pilot study for a randomized clinical trial

Area of Science:

• Neurology
• Clinical Trials
• Rehabilitation Medicine

Background:

• Sciatica, a common condition causing leg pain, necessitates effective treatment strategies.
• Evaluating treatment feasibility and patient compliance is crucial before large-scale clinical trials.

Purpose of the Study:

• To determine the feasibility of recruiting patients with sciatica.
• To assess patient compliance with different treatment modalities.
• To evaluate the responsiveness of key outcome measures for sciatica.

Main Methods:

• A pilot study involving 32 sciatica patients randomly assigned to spinal manipulation, epidural steroid injections, or self-care education.
• Outcome measures included Oswestry disability score, leg pain severity, and symptom bothersomeness.
• No between-group comparisons were planned due to the small sample size.

Main Results:

• Significant improvements were observed in Oswestry disability, leg pain severity, and symptom bothersomeness at 12 weeks (effect sizes 1.1-1.8).
• High patient satisfaction was reported, with 22/32 patients experiencing 75-100% improvement.
• Sustained improvements in leg pain and disability were noted at 52 weeks, with 15/32 patients reporting significant improvement.

Conclusions:

• Recruiting subacute and chronic sciatica patients for clinical trials is feasible.
• Patient compliance for a full-scale randomized clinical trial can be achieved.
• The chosen outcome measures are responsive to treatment changes in sciatica patients.
