Chronic low back pain often stems from various underlying factors, one of which is spinal instability. Despite its significance, there remains a lack of consensus regarding its precise definition and clinical relevance. Additionally, effective conservative treatment protocols have not been firmly established. Addressing this gap, in 2005 study conducted by M. Celestini et. al., sought to unravel the relationship between symptomatic characteristics and radiological findings in patients with lumbar instability. Furthermore, the study investigated the potential benefits of utilizing orthoses (braces) and rehabilitation techniques in managing pain and improving neuromotor function.

The research enrolled 48 patients aged 30 to 50, carefully selected based on specific exclusion criteria. These participants were randomly assigned to either the orthoses group (O group) or the orthoses with kinesitherapy group (O+KT group). Comprehensive assessments were conducted at four time intervals: baseline (t0), 3 months (t3), 6 months (t6), and 12 months (t12).

The study yielded intriguing insights into the nature of lumbar instability-related pain. Contrary to previous assumptions, the pain was found to be associated with vertebral shifting rather than hypermobility, particularly when accompanied by effective neuromotor feedback. Notably, the O+KT group demonstrated promising outcomes. This group experienced a dual benefit of reduced vertebral shifting and increased mobility without concomitant pain.

Over time, both groups showed an increasing trend in the utilization of orthoses, indicating potential long-term compliance with this therapeutic approach. In the O+KT group, an especially notable observation was the substantial reduction in the use of pain-relieving medications, suggesting a potential positive impact on overall patient well-being.

On the whole, the results of the treatment interventions were encouraging for both study groups, with reported decreases in pain levels. However, a significant divergence was observed in terms of neuromotor performance, favoring the O+KT group. This finding underscores the potential superiority of the combined orthoses and kinesitherapy approach in enhancing neuromotor function and possibly improving patients’ quality of life.

In conclusion, this randomized controlled trial sheds light on the intricate relationship between lumbar instability, pain, and functional limitations. The study provides preliminary evidence supporting the use of orthoses, particularly when complemented by kinesitherapy, in alleviating pain and promoting enhanced neuromotor performance. While further research is warranted to corroborate these findings and explore the mechanisms underlying these effects, this study represents a crucial step forward in the pursuit of effective treatments for patients grappling with chronic low back pain stemming from lumbar instability.
