Many case histories have shown that jaw malalignment can cause a wide spectrum of movement disorders: trigger finger, blink reflex, torticollis, scoliosis, poor gait, weak limbs, etc. Some of these case histories have also shown that dystonia is but another form of movement dysfunction often caused by jaw malalignment. That came to light this week when I examined a new patient with a Parkinson’s diagnosis. Her primary symptom was not tremor, but moderately severe dystonia. She could not sit in the exam chair without considerable twisting, turning, and head movement. When I propped her jaw open with bite material her dystonia immediately ceased by over 90%. Hence, once again the traditional Parkinson’s model based on neurotransmitter imbalances has failed to explain another aspect of the disease.
