A recent study explored the relationship between spinal degeneration, lumbar multifidus muscle (LMM) quality, and clinical outcomes in patients treated non-surgically with low back or leg pain. Key findings highlight the importance of muscle health in managing back pain and disability.
Results revealed that patients with higher-quality lumbar multifidus muscles experienced reduced disability scores over the year. Specifically, a 10% improvement in muscle quality correlated with a measurable reduction in disability. Conversely, patients with multiple spinal degenerative pathologies (four or more) experienced increased leg pain intensity, emphasizing the role of spinal health in pain management.
Interestingly, the research suggests that LMM quality and spinal degeneration independently influence pain and disability outcomes rather than one directly mediating the other. This means muscle health and spinal condition must be addressed separately for optimal patient outcomes.
Chiropractic care, which often includes targeted spinal adjustments and rehabilitative exercises, can improve muscle function and potentially reduce disability linked to back pain. The findings reinforce the importance of non-surgical, conservative care approaches for effectively managing back and leg pain.
“Patients with a higher proportion of healthy muscle at baseline showed greater improvement in their disability ratings at 12 months.”
“Higher LMM quality was also related to a small reduction in 12-month disability ratings, while higher numbers of degenerative pathologies were associated with increased leg pain intensity.”
“Chiropractic care, including manual therapy and rehabilitation strategies, can support muscle quality improvements and provide effective non-surgical management for patients with chronic low back pain.”
We believe patients have better outcomes when
their health professionals work together.
