Observational Study
Postoperative Changes in Moderate to Severe Nonspecific Low Back Pain After Cervical Myelopathy Surgery.
Cervical myelopathy patients sometimes experience concurrent nonspecific moderate to severe low back pain (msLBP). However, postoperative changes in msLBP after cervical myelopathy surgery have rarely been reported. Awareness of postoperative changes in msLBP may be helpful in consultation. Therefore, the objective of this study was to examine postoperative changes in msLBP. ⋯ Although the exact pathophysiology was not demonstrated, cervical myelopathy surgery may directly and indirectly improve msLBP.

Case ReportsSensory dissociation in chronic low back pain: Two case reports.
Patients with chronic low back pain often report that they do not perceive their painful back accurately. Previous studies confirmed that sensory dissociation and/or discrepancy between perceived body image and actual size is one of the specific traits of patients with chronic pain. Current approaches for measuring sensory dissociation are limited to two-point-discrimination or rely on pain drawings not allowing for quantitative analysis. ⋯ The latter pattern of sensory dissociation (i.e., pattern shrunk) is likely to respond to sensory training. Whether enlarged patterns of sensory dissociation are more resistant to treatment remains unknown but would explain the low effectiveness of previous studies using sensory training in chronic low back pain populations. Subgrouping patients according to their sensory discrimination pattern could contribute to the choice and effectiveness of the treatment approach.

There is a strong relationship between lower back pain and paraspinal muscle atrophy. In this study, we aimed to investigate the prevalence of lumbar paravertebral muscle atrophy in patients with and without single-level disc herniation. ⋯ The MM and erector spinae muscle groups are innervated by the dorsal root of the spinal nerve arising from the same level; therefore, long-term pressure on the root caused by disc herniation can cause atrophy and degeneration of that muscle group.
