Case Reports Randomized Controlled Trial
A prospective evaluation of anesthesia for posterior lumbar spine fusion: the effectiveness of preoperative epidural anesthesia with morphine.
A prospective, randomized, single-blinded study. ⋯ To combine preoperative epidural anesthesia with other anesthetic procedure for spinal fusion contributes to maintain more stable hypotension during surgery. As a result, it will be possible to lessen the bleeding during surgery. In addition, the postoperative pain was easily controlled with administration of fewer analgesic agents in patients who underwent the epidural anesthesia. The effectiveness of pre-emptive analgesia should be emphasized to diminish the postoperative pain.

Randomized Controlled Trial
The efficacy of corticosteroids in periradicular infiltration for chronic radicular pain: a randomized, double-blind, controlled trial.
A randomized, double-blind controlled trial. ⋯ Clinical improvement occurred in both groups of patients. Corticosteroids did not provide additional benefit.

Randomized Controlled Trial
A randomized clinical trial comparing two physiotherapy interventions for chronic low back pain.
A randomized clinical trial with blinded assessment. ⋯ Both forms of intervention were associated with significant improvement. On-going clinical research is necessary to provide guidance as to the clinical efficacy of various forms of intervention.

Randomized Controlled Trial
Looking away from whiplash: effect of head rotation in rear impacts.
Twenty healthy volunteers in a laboratory were subjected to rear-end impacts 4.4, 7.9, 10.9, and 13.1 m/s acceleration, with head rotation to the right and left. ⋯ If the head is rotated out of neutral posture at the time of rear impact, the injury risk tends to be greater for the sternocleidomastoid muscle contralateral to the side of rotation. Measures to prevent whiplash injury may have to account for the asymmetric response because many victims of whiplash are expected to be looking to the left or right at the time of collision.
