Exercise has been shown to reduce pain and increase function in patients with chronic low back pain. However up to 70% of patients do not engage in prescribed home exercise. Physiotherapists need to understand more about the complex factors influencing patients' adherence to prescribed home exercise to tailor their exercise interventions more effectively and support patients to self-manage. ⋯ This is the first systematic review investigating adherence to prescribed home exercise in a chronic low back pain population. It is difficult to draw firm conclusions because the research lacks detailed descriptions of intervention content. The use of a taxonomy of behavior change techniques has been suggested to overcome this key problem. This review has highlighted the lack of standardized measures of adherence to prescribed home exercise. The development of a validated measure of adherence should be a priority because this will provide a better understanding of the multitude of factors that may influence adherence to home exercise.

Review Case Reports
Epithelioid hemangioma of the spine: a case series of six patients and review of the literature.
Epithelioid hemangioma (EH) of bone is a benign vascular tumor that can be locally aggressive. It rarely arises in the spine, and the optimum management of EH of the vertebrae is not well delineated. ⋯ Our data suggest that EH of the spine can be locally aggressive and lead to instability and cord compression. Surgery is required in such instances; however, observation should be considered in patients without instability or cord compression.

With the increase of the elderly population, osteoporotic vertebral fractures have been frequently reported. Surgical intervention is usually recommended in osteoporotic vertebral collapse with neurologic deficits. However, very few reports on surgical interventions exist. ⋯ Anterior reconstruction for osteoporotic vertebral collapse is significant because anterior elements, particularly those at the thoracolumbar junction, play a major role in load bearing. However, difficulties arise when anterior reconstruction is performed in cases with very low bone density and in those with multiple vertebral collapse.

Reliability of the clinical examination in the diagnosis of neurogenic versus vascular claudication.
As research increasingly challenges the diagnostic accuracy of advanced imaging for lumbar spinal stenosis, the impression gleaned from the office evaluation becomes more important. Neurogenic claudication is a hallmark of lumbar spinal stenosis, but the reliability of clinical impression of claudication has not been studied. ⋯ The clinical impression of neurogenic claudication is a reliable construct. The history, but not the poorly reproduced physical examination, contributes to reliability. The level of disagreement between experts in this simplified, yet severely involved, population raises concern about the risk of misdiagnosis in individual cases. Thus, surgical and other consequential decisions about diagnosis may require ancillary tests such as electromyography or ABI.
