Writer's cramp, or mogigraphia, refers to a disorder of the hand, due to excessive fine motor activity, such as writing or playing the piano. It is referred to medically as "task-specific focal dystonia of the hand." more...
Mogigraphia is thought to result from a problem of control involving the basal ganglia of the brain. As well as writers, musicians have also been affected, including Leon Fleischer whose performance career was limited for a time to performance of piano concertos for the left hand alone.
Focal dystonias can be treated with injections of Botox (Botulinum Toxin) in the affected muscle groups to paralyze the overactive muscles. Postural techniques such as the Alexander Method are also effective in some cases.
