Programming Directional Deep Brain Stimulation in Parkinson's Disease: A Randomized Prospective Trial Comparing Early...

Area of Science:

• Neurosurgery
• Neurology
• Biomedical Engineering

Background:

• Programming directional leads for deep brain stimulation (DBS) presents challenges, with no established optimal strategy.
• Subthalamic nucleus DBS is a key treatment for Parkinson's disease.

Purpose of the Study:

• To establish an evidence-based programming algorithm for Parkinson's disease patients using directional leads.
• To compare the efficacy of early versus delayed steered stimulation programming.

Main Methods:

• A randomized controlled study involving 14 Parkinson's disease patients undergoing subthalamic nucleus DBS with directional leads.
• Patients were randomized to early or delayed steered stimulation programming.
• Outcomes included motor scores, programming visits, clinic calls, battery consumption, and stimulation adjustments over 3 months.

Main Results:

• Thirteen patients (25 electrodes) were analyzed; 23 electrodes were steerable.
• Nine of 14 electrodes in the delayed group were switched to steered mode due to side effects.
• No electrodes in the early group were converted to ring mode; no significant differences were observed between groups at 3 months.

Conclusions:

• Both early and delayed steered stimulation programming are equally effective in the short term for Parkinson's disease.
• Delayed steering may be less time-consuming and not always necessary, suggesting potential efficiency gains.
