## Abstract Fifteen patients with torticollis who had been treated with repeated injections of botulinum toxin type A (botox A) developed antibodies to the toxin. This resulted in loss of benefit in the 13 patients who had improved with botox A injections and failure to develop muscle atrophy after

β¦ Synopsis
Abstract
Improvement in cervical range of motion in patients with spasmodic torticollis by botulinum A toxin injection is difficult to objectively measure. Recently, a threeβdimensional cervical range of motion system (EMROM) that measures primary as well as secondary cervical angles has been developed. This system uses an electromagnetic tracking system for data collection and a personal computer for analysis and graphic display of the data. We have tested the EMROM system and, from our results, believe that it can be used clinically to objectively and accurately measure cervical range of motion in patients who have spasmodic torticollis and who receive botulinum toxin injections.

## Abstract Between 1984 and 1992, 559 patients with torticollis were treated with botulinum toxin type A (btx) injections. Twentyβfour of these 559 patients (4.3%) had serological evidence of antibodies to btx by mouse neutralization assay. Some of the 559 patients had only one or two injection se
## Abstract We followed the course in 100 consecutive patients with cervical dystonia (CD) after they were initially treated with botulinum toxin (BTX) in the form of Dysport 10 to 12 years ago. A total of 4 patients had died, and 6 were lost to followβup. Of the remaining 90 patients, 57 (63%) wer
## Abstract We treated 43 patients who had head tremor as the major complaint with local botulinum toxin type A (Btx A) injections into neck muscles: 29 patients were classified as suffering from tremulous cervical dystonia (TCD), and 14 had head tremor without dystonia (HT). All patients were clin
