Abstract: | The complaint of hand cramps is common among patients who consult the neurologist or the hand surgeon. Classic writer's cramp is best characterized as a focal dystonia, and electromyographic studies reveal a characteristic pattern of cocontraction of the agonist and antagonist muscles of the forearm and hand. Although the outcome of treatment in the past has been unsatisfying, recent experience with new pharmacologic therapy, such as injections of botulinum toxin, has produced promising results. Further experience and improvement in this area will likely increase the therapeutic success in the treatment of writer's cramp and other focal dystonias. |
