Spontaneous wriggling or writhing movements which can occur when the medicine is working (i.e. the patient is 'on').
A rhythmic, oscillating movement, most commonly of the hands and or limbs.
When the patient is adequately treated and movements are reasonably fluent and spontaneous.
When when the patient's medication has worn off and movements are slow, deliberate and difficult. Other less visible symptoms of pain and distress may be a feature for some patients.
A noticeable transition from 'on' to 'off' occurring between doses of medication.
An umbrella term for the motor complications of more 'brittle' advanced disease. Patients can fluctuate from 'off', to 'on' and "on with dyskinesia." The change may be gradual or a sudden switch.
