Battery-preserving Stimulation Patterns for Deep Brain Stimulation

NCT02569021 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 30

Last updated 2016-10-24

No results posted yet for this study

Summary

The purpose of this research study is to test effectiveness of different deep brain stimulation (DBS) stimulation patterns on symptoms that may also improve the life of the battery. If these patterns are effective, the implanted batteries will be drained more slowly and last longer than currently expected. An increase in battery life may reduce the number of surgeries needed to replace them.

Conditions

Interventions

DEVICE

Biphasic DBS stimulation

The following protocol will be followed for each subject. In between, baseline and novel stimulation settings there will be a 30-minute washout period with DBS in the off state. 1. Current best/optimized DBS setting (considered "baseline") 2. DBS off for 30 minutes as a washout period 3. Biphasic pulse stimulation mode (assessment at 0.5hr) 4. Biphasic pulse stimulation mode (assessment at 1hr) 5. Biphasic pulse stimulation mode (assessment at 2hr) 6. Biphasic pulse stimulation mode (assessment at 3hr)

OTHER

Unified Parkinson's Disease Rating Scale

UPDRS is used by neurologists to rate the motor impairment of people with Parkinson's Disease.

OTHER

Tremor Rating Scale

TRS is used by neurologists to rate the severity of a tremor.

DEVICE

Kinesia accelerometer

The kinesia accelerometer is used to analyze the tremor and slowness (bradykinesia) of the participants.

DEVICE

Trigno wireless system

The Trigno system measure muscle contractions.

OTHER

GaitRite walking assessment.

GaitRite records a patients gait pattern.
