6 patients with jaw-closing dystonia will be treated with neuromuscular electrical stimulation over 8 weeks. The distance the mouth can be opened voluntarily and the oro-mandibular dystonia questionnaire (OMDQ-25) will be employed to determine whether there is any objective change in jaw opening or evidence of functional improvement.

Jaw Opening
Measured via tongue depressor quantity, which is the number of stacked tongue depressors the patient is able to safely fit between his or her incisors.
Time frame: Change from before starting first treatment to after completing last treatment, usually completed over 8 weeks.
Jaw Opening
Measured via tongue depressor quantity, which is the number of stacked tongue depressors the patient is able to safely fit between his or her incisors.
Time frame: Average change from before to after each 20-minute treatment session.
Oromandibular Dystonia Questionnaire
Questionnaire that assesses quality of life in oromandibular dystonia patients. There are 25 questions total, and each question may be answered as never, seldom, sometimes, often, always. Minimum score is 0, maximum score is 100. A higher score indicates worse quality of life.
Time frame: Change from before the first treatment to after the last treatment, usually over 8 weeks.
