A validation study of the Acute Low Back Pain Screening Questionnaire Dutch Language Version (ALBPSQ-DLV). ⋯ The internal consistency and both construct and convergent validity of the ALBPSQ-DLV are well established in a Dutch population of 69 patients with (sub) acute nonspecific LBP referred to primary care physical therapy.

Laboratory investigation, ex vivo. ⋯ The low degree of heating and minor artifacts associated with the Resolve-based cervical external immobilization devices indicated that these products are safe for patients undergoing MRI at 3-Tesla.

Mechanical testing of cadaveric spines. ⋯ When the ageing spine is compressed, vertebral bodies show greater elastic deformations than intervertebral discs, and creep by a similar amount. Responses to axial compression depend largely on IDP, but deformations appear to be limited by impaction of adjacent neural arches. Total compressive deformations are sufficient to cause foraminal stenosis in some individuals.

Neck-pain and control group comparative analysis of conventional and virtual reality (VR)-based assessment of cervical range of motion (CROM). ⋯ Neck pain is significantly associated with reduced CROM as demonstrated by both VR and conventional assessment methods. The VR method provides assessment of functional CROM and can be used for CROM enhancement. Assessment by VR has greater sensitivity than conventional assessment and can be used for the detection of true symptomatic individuals.

We describe an innovative single-stage reduction and stabilization technique using modern cervical instrumentation. ⋯ In this article we will discuss the clinical cases and review the background of craniocervical junction abnormalities in Down's syndrome patients. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination.
