A retrospective, comparative follow-up study. ⋯ Circumferential fusion provided significantly better long-term clinical, radiographic, and SRS total score than posterolateral or anterior fusion for high-grade isthmic spondylolisthesis.

Exploratory experimental design. ⋯ Coupled movements are a natural part of cervical motion together with primary movements and follow specific patterns in subjects with no symptoms of neck disorders. Our study shows that cervical motion alters throughout life according to specific patterns but with individual variations.

Comparative Study Controlled Clinical Trial
Head repositioning accuracy in patients with whiplash-associated disorders.
Controlled study, measuring head repositioning error (HRE) using an electrogoniometric device. ⋯ In patients with WAD, range of motion and head repositioning accuracy were reduced. However, the differences were small. Vision suppression and task type influenced HRE.

Comparative Study
Intradiscal thermal therapy does not stimulate biologic remodeling in an in vivo sheep model.
Thermal energy was delivered in vivo to ovine cervical discs and the postheating response was monitored over time. ⋯ While a high temperature thermal protocol had a detrimental effect on the disc, the effects of low temperature treatment were relatively minor. Thermal therapy did not stimulate significant biologic remodeling. Future studies should focus on the effects of low-dose therapy on tissue innervation and pro-inflammatory factor production.

Comparative Study
A population-based analysis of healthcare utilization of persons with back disorders: results from the Canadian Community Health Survey 2000-2001.
A retrospective, population-based analysis. ⋯ With increasing disability as indicated by the presence of pain and functional limitations, and the presence of depressive symptoms, the higher the utilization of physician and nonphysician resources, with the exception of chiropractic care, which appears to be used by those with less severe symptoms. Lower socioeconomic status was associated with significantly lower receipt of services for almost all healthcare providers.
