Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Due to the exploratory nature of the study no formal primary endpoints have been defined. Collected data will be used to guide product development and to build early experience to define the best practice for programming. | — |
Secondary
| Measure | Time frame |
|---|---|
| Exploratory endpoints are: • Amplitude (mA) of stimulation induced side effect threshold during intra-operative testing. • Amplitude (mA) difference between efficacy threshold for control of rigidity and first limiting stimulation induced side effect threshold, i.e. *therapeutic window*, for all evaluated settings at Programming Visits - Day 1, 2 and 3 • UPDRS III Scores for selected settings at Programming Visits - Day 1, 2 and 3 and at Randomization, Crossover, Release, and 1 Year Follow Up Visits • Kinesia ONE scores for selected settings at Programming Visits - Day 1, 2 and 3 and at Randomization, Crossover, Release, and 1 Year Follow Up Visits • PDQ-39 Scores at Randomization, Crossover, Release, and 1 Year Follow Up Visits • Kinesia 360 motor diary scores during Crossover Arms 1 and 2 | — |
