Comparative Study
Association of back pain frequency with mortality, coronary heart events, mobility, and quality of life in elderly women.
A 5-year observational cohort design using data from a randomized controlled trial of calcium intervention. ⋯ Daily back pain is associated with reduced quality of life, mobility and longevity and increased risk of coronary heart events. The adverse health effects of chronic back pain deserve greater recognition.

Comparative Study
Different effects of static versus cyclic compressive loading on rat intervertebral disc height and water loss in vitro.
In vitro biomechanical study on rat caudal motion segments to evaluate association between compressive loading and water content under static and cyclic conditions. ⋯ Peak magnitude of cyclic compression and not RMS value was most important in determining height change and water loss, likely due to differences between disc creep and recovery rates. Water redistribution from nucleus to anulus occurred under loading consistent with an initial elastic compression (and associated disc bulge) followed by a reduction in disc volume over time.

Randomized Controlled Trial Comparative Study
Laminoplasty and skip laminectomy for cervical compressive myelopathy: range of motion, postoperative neck pain, and surgical outcomes in a randomized prospective study.
A prospective randomized clinical trial in surgical treatment for cervical compressive myelopathy. ⋯ No significant differences were seen between Lamino and Skip groups, in terms of operative invasiveness, axial neck pain, cervical alignment, and ROM, and clinical results in the patients of CSM without developmental stenosis.

Randomized Controlled Trial Comparative Study
Cost-effectiveness of physical therapy and general practitioner care for sciatica.
An economic evaluation alongside a randomized clinical trial in primary care. A total of 135 patients were randomly allocated to physical therapy added to general practitioners' care (n = 67) or to general practitioners' care alone (n = 68). ⋯ The treatment of patients with LRS with physical therapy and general practitioners'care is not more cost-effective than general practitioners'care alone.
