Medical Care

  • Approximately 5% of patients have spontaneous remission, most probably in the first 5 years. However, the majority of these patients have relapses.
  • Treatment is generally disappointing.
  • Transcutaneous electrical nerve stimulation (TENS) delivered to the forearm flexor muscles for a 2-week period has been found to improve symptoms for up to 3 weeks after treatment.[1]
  • Behavioral changes may help.
  • Biofeedback, hypnotherapy, and relaxation therapy have been tried.
  • Thalamotomy and thalamic deep brain stimulation for severe cases has been reported to be successful.[2]

Activity

  • Altering the grip of the pen and/or increasing the diameter of the pen used is the first step in treatment.
  • Patients can use a writing device or other means of transcription, such as typing or dictation.
