Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1. Participant is willing and able to give informed consent for participation in the study 2. Male or female, aged 18 to 80 years old 3. Diagnosed with Parkinson’s disease, essential tremor or dystonia 4. Has completed stage 1 of a two-stage surgery for deep brain stimulation as therapy for their movement disorder

Exclusion criteria

Exclusion criteria: 1. Cognitive impairment (judged by the clinician taking consent as not having sufficient mental capacity to understand the study and its requirements). This is including anyone who, in the opinion of the clinician taking consent, is unlikely to retain sufficient mental capacity for the duration of their involvement in the study 2. Intracranial bleeding, cerebrospinal fluid leak or any other complication after the first stage of surgery

Design outcomes

Primary

MeasureTime frame
Measured before and after feedback-controlled stimulation: 1. Kinematic recordings (accelerometer and BRAIN test in all patients) related to movement speed, spasms and the presence of tremor 2. Scores on standard, disease-specific clinical rating scales (UPDRS and UDysRS in Parkinson’s disease, TETRAS in essential tremor and BFMRS and UDysRS in dystonia) and on Speech Intelligibility Test (all patients) 3. Scalp EEG (brain waves), depth EEG and EMG (muscle) recordings (all patients)

Secondary
