Deep brain stimulation (DBS) uses one or two surgically implanted medical devices called neurostimulators, similar to cardiac pacemakers, to deliver electrical stimulation to precisely targeted areas on each side of the brain. Stimulation of these areas appears to block the signals that cause the disabling motor symptoms of Parkinson’s. As a result, many patients achieve greater control over their body movements. DBS is used mainly to treat people with advanced Parkinson’s disease, but also other movement disorders such as essential tremor and dystonia.
Further information on DBS can be found in the Deep Brain Stimulation [DBS] section of this site.
Involuntary sustained muscle contractions causing abnormal movements and postures.
See section on Dystonia.
ET is a common neurological condition, often misdiagnosed as Parkinson’s. Its cause is unknown, but can run in families, resulting in fast, rhythmic trembling in the hands, head, legs, trunk or voice. Whilst the tremors experienced by people with Parkinson’s are apparent during rest periods, ET is an ‘action’ tremor - it is more pronounced when the affected part of the body is being used, for example in the hands when writing.

Those affecting movement, e.g. tremor, rigidity, bradykinesia and freezing.
Collective name for conditions that affect a person’s abilities to produce and control movement. They include Parkinson’s disease, restless leg syndrome and dystonia.
A pacemaker-like device that is the power source for the deep brain stimulation system. It is implanted in the patient’s chest and contains a small battery and computer chip programmed to send electrical pulses to control Parkinson's symptoms.
