Low back pain (LBP) is a highly prevalent disease. Among the various causes of LBP, one of the most frequent is myofascial pain syndrome (MPS) which affects the spinal stabilizer muscles. The aims of this study were to compare the differences in muscular electrical activity and biomechanical...

This study looked at people with one-sided lower back muscle pain (myofascial pain syndrome, or MPS) and compared the muscle activity and stiffness on the painful side to the non-painful side. They used two tools—surface electromyography (sEMG) and MyotonPRO a standardized digital palpation device to measure mechanical stiffness of biological tissues—to measure muscle electrical activity and mechanical properties.
Here’s what they found:
- Before treatment: The muscles on the painful side were more active and showed differences in how they moved and responded compared to the non-painful side. The painful muscles had higher electrical signals, which means they were overactive, but there wasn’t much difference in muscle stiffness or elasticity.
- After treatment: After a single session of platelet-rich plasma (PRP) treatment, the muscle activity on the painful side decreased, and patients reported less pain and better movement. This showed that the PRP treatment helped reduce muscle overactivity and improve symptoms.
In summary, using sEMG and MyotonPRO can help identify muscle problems in people with MPS, and PRP treatment may be effective in reducing pain and improving muscle function.
