Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized controlled trial of exercise and manipulative therapy for cervicogenic headache.
A multicenter, randomized controlled trial with unblinded treatment and blinded outcome assessment was conducted. The treatment period was 6 weeks with follow-up assessment after treatment, then at 3, 6, and 12 months. ⋯ Manipulative therapy and exercise can reduce the symptoms of cervicogenic headache, and the effects are maintained.

Randomized Controlled Trial Multicenter Study Clinical Trial
Combined magnetic fields accelerate and increase spine fusion: a double-blind, randomized, placebo controlled study.
The clinical study conducted was a prospective, randomized, double-blind, placebo-controlled trial. ⋯ In conclusion, the adjunctive use of the combined magnetic field device was statistically beneficial in the overall patient population, as has been shown in previous studies of adjunctive bone growth stimulation for spine fusion. For the first time, stratification of fusion success data by gender demonstrated that the female study population responded positively to the adjunctive combined magnetic field treatment, with no statistically significant effect observed in the male study population. Adjunctive use of the combined magnetic field device significantly increased the 9-month success of radiographic spinal fusion and showed an acceleration of the healing process.

Multicenter Study Comparative Study Clinical Trial
A pilot study on the recovery from paresis after lumbar disc herniation.
Although the existence of a motor defect in discogenic sciatica is a sign of severity, the literature does not provide evidence for an immediate requirement for surgery. ⋯ This pilot study showed no difference between surgical or medical management for recovery or improvement in patients with discogenic paresis. These results need confirmation by a randomized study.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Chronic low back pain and fusion: a comparison of three surgical techniques: a prospective multicenter randomized study from the Swedish lumbar spine study group.
A multicenter randomized study with a 2-year follow-up period and an independent observer was conducted. ⋯ All the fusion techniques used in the study could reduce pain and improve function in this selected group of patients with severe chronic low back pain. There was no obvious disadvantage in using the least demanding surgical technique of posterolateral fusion without internal fixation.

Multicenter Study
The role of fluoroscopy in cervical epidural steroid injections: an analysis of contrast dispersal patterns.
A multicenter, retrospective analysis of cervical epidurograms. ⋯ The loss of resistance technique may not be an adequate method for ensuring accurate needle placement in blindly performed cervical epidural injections. The use of epidurography can improve the accuracy of needle placement and medication delivery to targeted areas of pathology.
