Clinical Trial Summary

The purpose of this study is to compare the effectiveness of the deep brain stimulation of asymmetric targets [subthalamic nucleus (STN) in the right hemisphere while globus pallidus interna (GPi) in the left] versus the bilateral STN for the treatment of Parkinson's disease (PD) with postural instability/gait difficulty (PIGD) in a randomized, double-blinded manner.

Description:

This is a double-blinded, randomized, controlled trial aiming at comparing the efficacy of asymmetric targets and bilateral STN DBS in treating PD with PIGD.

After being informed about the study and potential risks, enrolled patients giving written informed consent will be screened to determine eligibility for study entry. Patients who meet the eligibility requirements will be randomized into two groups in a 1:1 ratio using a minimization randomization method in a double-blinded manner, and later undergo bilateral DBS surgery. One group of patients will receive stimulation of left GPi and right STN, while the other will receive STN stimulation bilaterally. The follow-up period will be one year, with corresponding clinical assessments completed at six months and one year postoperatively.

Eligibility

Inclusion Criteria:

• postural instability/gait difficulty (PIGD) phenotypes in the on-medication condition

Exclusion Criteria:

• Atypical parkinsonism

• History of stroke, encephalitis, neuroleptic uses, MRI scan with evidence of significant brain atrophy, lacunar infracts, or other conditions that might interfere with intracranial surgery

• Presence of cognitive, or psychiatric or other co-morbidities (e.g., dementia, epilepsy, cranial traumatism, brain tumor, schizophrenia, severe depression or bipolar disorder, personality disorder, etc.) that might interfere with the patient's ability to complete the evaluations or to provide informed consent

• Presence of anatomical abnormalities in the target region

• Clinically significant medical history that would increase pre-/post-operative complications

• Other conditions considered by the investigators that might interfere with the surgery procedure, the follow-ups, and the interpretation of the data
