Abstract

Deep brain stimulation (DBS) is used to alleviate tremor in patients diagnosed with Essential Tremor who do not respond to conventional treatments. To achieve optimal tremor suppression, a large stimulus parameter space needs to be explored. In practice, a default pulse duration and stimulation rate (generally 60 us and 130 Hz) are often chosen and current or voltage varied to determine a clinically effective setting. This study explored the effect of rate of stimulation in 5 patients with bilateral DBS stimulation to the posterior sub-thalamic area (PSA). Additionally, the effects of varying charge per pulse by varying pulse duration alone or by varying current/voltage alone were compared. ..
