NCT01934881

Brief Summary

The programming of subthalamic nucleus (STN) deep brain stimulation (DBS) for Parkinson's disease (PD) is complex work because the parameter setting has not been standardized so far. The objective of the present study is to set up a standardized programming algorithm for Chinese PD patients treated with bilateral STN DBS.

Outcome Measures

Primary Outcomes (1)

  • Changes in motor symptoms (tremor, rigidity, bradykinesia and postural stability) evaluated by MDS-UPDRS Part III in off medication /on stimulation state

    Motor subscores

    From baseline to 12 and 48 months

Secondary Outcomes (2)

  • Changes in 39-item Parkinson's Disease Questionnaire (PDQ-39) scores

    From baseline to 12 and 48 months

  • Changes in levodopa equivalent daily dosage (LEDD)

    From baseline to 12 and 48 months

Study Arms (2)

group I

Voltage adjustment only

Device: voltage adjustment only

group II

Multiple parameters adjustment

Device: Multiple parameters adjustment

Interventions

Only voltage will be adjusted in all programming sections.

group I

More than one parameter, including voltage, frequency and pulse width, will be adjusted in the programming sections.

group II

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

PD Patients are selected from the outpatient department of three centres.

You may qualify if:

  • The patients with the idiopathic Parkinson's disease with good response to levodopa medication (i.e. more than 30% improvement in the MDS-UPDRS Part III score of the motor function examination(Goetz et al., 2008b) after an acute levodopa medication challenge);
  • Disease duration ≥4 years;
  • The patients with the fluctuations and/or dyskinesias;
  • The patients with age ranging from 18 to 75 years old;
  • The patients with normal brain on the MRI;
  • The patients with the absence of dementia (Mini-Mental State Examination scores of≥ 26) ;
  • The patients with the absence of severe psychiatric diseases;
  • The patients who provided the written informed consent

You may not qualify if:

  • The patients with severe metabolic diseases;
  • The patients with severe cardiac/respiratory/renal/hepatic diseases;
  • The patients having secondary parkinsonism or multiple system atrophies;
  • The patients who illiterate or having insufficient language skills to complete the questionnaires;
  • The patients who had poor compliance and unreasonable expectation;
  • Women who were pregnant or breast feeding;
  • The patients with the simultaneous participation in another clinical trial
