Randomized Controlled Trial Comparative Study
One-year follow-up comparison of the effectiveness of McKenzie treatment and strengthening training for patients with chronic low back pain: outcome and prognostic factors.
A randomized controlled trial with multivariable analyses of prognostic factors. ⋯ Poor long-term outcome of exercise therapy for chronic low back pain can be explained by a number of patient-related factors. Different prognostic factors were associated with different outcomes. These factors were more important in determining outcome than the exercise-programs studied.

Comparative Study
From chronic low back pain to disability, a multifactorial mediated pathway: the InCHIANTI study.
Clinicoepidemiologic study in the Chianti area (Tuscany, Italy). ⋯ The cross-sectional association between LBP and self-reported disability, in specific tasks is modulated by performance measures. Specific performance-based tests that explore the functional consequences of LBP may help design specific interventions of disability prevention and treatment in patients with LBP.

Comparative Study
An outcome measure for Japanese people with chronic low back pain: an introduction and validation study of Japan Low Back Pain Evaluation Questionnaire.
Development of a nationwide patient-based outcome measure for patients with chronic low back pain (CLBP). ⋯ The JLEQ was shown to be a valid and reliable questionnaire scale for measurement of patient-based outcomes in CLBP patients.

Retrospective study of consecutive patient series. ⋯ Most common causes of revision spine surgery due to sagittal imbalance were failure to enhance lumbar lordosis and adjacent disc degeneration after lumbar fusion surgery. These patients were effectively treated with a combined anterior and posterior arthrodesis. Following these surgical treatment, sagittal balance was generally improved with fair-to-good clinical outcomes, high patient satisfaction, and low perioperative complication rates.

Case Reports Comparative Study
Spinal cord injury in patients with ankylosing spondylitis: a 10-year review.
Retrospective study. ⋯ Neurologic deficits were often subtle on initial presentation, resulting in many injuries being missed because of a low index of suspicion and poor visualization of lower cervical fractures on conventional radiographs. Extension of the ankylosed kyphotic cervical spine during conventional immobilization or for radiologic procedures resulted in neurologic deficits. Patients with an ankylosed cervical spine are normally unable to see the ceiling lying supine because of cervicothoracic kyphosis and use pillows to support their head. Cervical spine alignment in a similar flexed position is essential during immobilization or imaging. Medical alert cards as for patients with diabetes would be a way forward in correctly identifying patients with AS so that appropriate precautions can be instituted by emergency services.
