Summary
Supervised exercise significantly improved satisfaction and trunk strength for chronic low back pain (CLBP) compared to spinal manipulation or home exercise. However, patient-rated outcomes like pain and disability showed minimal, non-significant differences across groups.
Area of Science:
- Orthopedics
- Physical Therapy
- Rehabilitation Medicine
Background:
- Conservative therapies, including exercise and spinal manipulative therapy (SMT), are used for chronic low back pain (CLBP).
- The effectiveness of less time-intensive self-care interventions like home exercise for CLBP is not definitively established.
Purpose of the Study:
- To compare the relative effectiveness of supervised exercise, spinal manipulation, and home exercise for treating CLBP.
Main Methods:
- A 12-week, observer-blinded, mixed-method randomized clinical trial involving 301 adults (18-65 years) with mechanical LBP of at least 6-week duration.
- Outcomes included patient-reported pain, disability, general health, medication use, satisfaction, and blinded assessments of trunk muscle endurance and strength.
Main Results:
- All treatment groups showed improvement over 12 weeks.
- Supervised exercise yielded the highest satisfaction and greatest gains in trunk muscle endurance and strength.
- No statistically significant differences were observed between groups for patient-rated pain and disability in the short or long term.
Conclusions:
- Supervised exercise demonstrated superior outcomes in treatment satisfaction and trunk muscle function compared to spinal manipulative therapy and home exercise for CLBP.
- While supervised exercise consistently favored patient-reported pain and disability, these differences were not statistically significant.
