Randomized Controlled Trial
Prone versus knee-chest position for microdiscectomy: a prospective randomized study of intra-abdominal pressure and intraoperative bleeding.
Prospective randomized study. ⋯ Intra-abdominal pressure did not differ between prone position on a modified Relton-Hall frame and knee-chest position on an Andrew-type table. Both positions provide good conditions for lumbar microdiscectomy.

The effect of sensory motor learning (SML) on chronic low back pain (CLBP) patients' movement capacity was evaluated with the optoelectronic Posturo-Locomotion-Manual (PLM) test. ⋯ The study shows that the CLBP patients had learned and retained a more efficient behavior. The results suggest that SML is an effective intervention for nonspecific CLBP patients.

Prospective cohort study. ⋯ The Bryan artificial cervical disc provided in vivo functional spinal motion at the operated level, reproducing the preoperative kinematics of the spondylotic disc.

Comparative Study
Intervertebral motion after incremental damage to the posterior structures of the cervical spine.
Compare intervertebral motion after incremental damage to posterior cervical structures in whole cadavers to motion in asymptomatic subjects. ⋯ Radiographic assessment of the cervical spine may not be sufficient to exclude even extensive damage to the posterior structures of the cervical spine.

Prospective longitudinal study of patients attending a back pain triage clinic with night pain. ⋯ Although it is a significant and disruptive symptom for patients, these results challenge the specificity of the presence of night pain per se as a useful diagnostic indicator for serious spinal pathology in a back pain triage clinic.
