Randomized Controlled TrialEffect of dronabinol on central neuropathic pain after spinal cord injury: a pilot study.
To test the efficacy and safety of a cannabinoid, dronabinol, compared with an active control, diphenhydramine, in relieving neuropathic pain in persons with spinal cord injury. ⋯ On average, dronabinol was no more effective than diphenhydramine for relieving chronic neuropathic pain below the level of injury.

Randomized Controlled TrialReliability, construct validity, and responsiveness of the neck disability index, patient-specific functional scale, and numeric pain rating scale in patients with cervical radiculopathy.
To examine the psychometric properties of the Neck Disability Index, Patient-Specific Functional Scale, and the Numeric Pain Rating Scale in a cohort of patients with cervical radiculopathy. ⋯ In light of the varied distribution of symptoms in patients with cervical radiculopathy, future studies should investigate the psychometric properties of other neck-related disability measures in this patient population.

Effect of botulinum toxin on pressure pain threshold and EMG power spectrum of masseter muscle during sustained fatiguing contraction.
The aims of this study were to test the effect of botulinum toxin on a reversible, prolonged, experimental pain and on muscle fatigue in human masseter muscle, both caused by a sustained clench. ⋯ We interpret the reduced change in pressure pain threshold with botulinum toxin as a clinically modest but statistically significant analgesic effect on this model of acute muscle pain.

The effect of back school integrated with core strengthening in patients with chronic low-back pain.
To assess the effect of back school integrated with core-strengthening exercises on back-specific disability and pain-coping strategies and to examine how reactions to pain affect the outcomes of back school in patients with chronic low back pain. ⋯ Our back school program may help patients with chronic low back pain reduce back-specific disability and pain and develop wellness-focused coping strategies such as exercise and stretching.

Randomized Controlled TrialComparison between botulinum toxin and corticosteroid injection in the treatment of acute and subacute tennis elbow: a prospective, randomized, double-blind, active drug-controlled pilot study.
To compare botulinum toxin type A injection with corticosteroid injection in the treatment of tennis elbow. ⋯ Corticosteroid is superior to botulinum toxin type A in relieving pain in tennis elbow at 4 wks after injection. Because botulinum toxin injection did not relieve pain significantly but is associated with weakness, the muscle weakness caused by botulinum toxin is unlikely to be the sole mechanism of the pain relief observed in previous studies.
