Main Methods:

• Comparison of voltage and current sources in DBS systems.
• Analysis of electrode design, polarity configurations, and electrical signal parameters (rate, amplitude, pulse width).
• Evaluation of interleaving stimulation techniques and system rechargeability.

Main Results:

• Differences in voltage/current sources impact stimulation characteristics.
• Electrode design, polarity, and signal parameters allow for precise shaping of the stimulation field.
• Interleaving stimulation offers potential for improved treatment outcomes.
• System rechargeability and component interoperability are discussed.

Conclusions:

• Technical features of DBS systems, including electrode design, electrical parameters, and stimulation strategies, are critical for optimizing therapeutic benefits and minimizing side effects.
• Understanding these technical variations is essential for tailoring DBS therapy to individual patient needs.
