Unlabelled: Though the pathophysiology of dystonia remains uncertain, two primary factors implicated in the development of dystonic symptoms are excessive cortical excitability and impaired sensorimotor processing. The aim of this study was to determine the functional efficacy of an intervention combining repetitive transcranial magnetic stimulation (rTMS) and sensorimotor retraining. A randomized, single-subject, multiple baseline design with crossover was used to examine participants with focal hand dystonia (FHD) (n = 9).

These virtual bladder models can be deformed by a cystoscope model or penetrated by a needle model.

The study investigators hypothesized that intra-articular BoNT-A would result in statistically significant improvements in pain and function at 8 weeks.
Design: Double-blind, randomized, single tertiary care academic medical center trial with 6-month follow-up.
There is a growing need for novel treatments of refractory arthritis joint pain as the aging population is expanding with many patients who are unable to undergo joint replacement surgery. We are studying the efficacy and safety of intra-articular injection of Botulinum Toxin Type A (IA-BoNT/A) into joints with arthritis pain. In several small open label studies, initial effects for IA-BoNT/A were encouraging because two thirds of the patients had more than 50% reduction in joint pain severity that was associated with a significant improvement in function.

Study Design: Open-label, dose-escalation, pilot study. Primary outcome measure was a standard numeric pain rating scale of 0-10.
We describe 2 patients, one with cervical dystonia (CD) combined with focal hand dystonia (writer's cramp) and another with idiopathic CD, who were unresponsive to oral medications and became resistant to botulinum toxin type A and B injections. Both patients were successfully treated with high cervical (C1-3) continuously infused intrathecal baclofen (ITB). Neck range of motion (ROM) was measured by using a 3-dimensional electromagnetic cervical ROM system.

The purpose of this study was to determine the efficacy and safety of botulinum toxin type B (BTX-B/Myobloc) in the treatment of patients with overactive bladder. This open-label dose-escalation study enrolled 15 female patients with urinary frequency with or without incontinence. The BTX-B doses used in this study were 2500, 3750, 5000, 10 000 and 15 000 units.

Botulinum toxin inhibits release of acetylcholine and other neurotransmitters. It has been used successfully to treat pain and abnormal skeletal and smooth muscle activity in patients. This article discusses its use in patients with bladder and bowel disorders.

This patient was successfully treated with 2 separate injections of botulinum toxin type B into the bladder. The results of the treatment lasted 4 months and there were no side effects.
