Summary
Low back pain patients do not consistently show elevated paraspinal electromyography (EMG) levels. Reducing EMG is unlikely to be a key part of biofeedback therapy for back pain.
Area of Science:
- Biomedical Engineering
- Clinical Neuroscience
- Rehabilitation Medicine
Background:
- Two models propose relationships between paraspinal electromyography (EMG) and low back pain.
- Existing literature on these models' predictions is reviewed.
Purpose of the Study:
- To evaluate the evidence supporting proposed models of paraspinal EMG in low back pain.
- To assess the role of EMG reduction in biofeedback therapy for low back pain.
Main Methods:
- Literature review of studies on paraspinal EMG and low back pain.
- Discussion of recent research focusing on EMG patterns versus absolute levels.
Main Results:
- No consistent evidence supports elevated paraspinal EMG in low back pain patients.
- Evidence does not suggest EMG reduction is crucial for biofeedback therapy efficacy.
Conclusions:
- Current evidence does not support the hypothesis that low back pain is associated with elevated paraspinal EMG.
- Treatments modifying paraspinal EMG patterns are considered experimental due to preliminary research.
