Table 1. Change (Δ) in Mean Power with Respect to Baseline.

DBS Set (number of sides)	Alpha (8–12 Hz)	Beta (13–35 Hz)
130 Hz/2V	Δ = -0.265	Δ = -0.431
(N = 14)	↓ P < 0.001	↓ P < 0.001
130 Hz/1.35V	Δ = -0.0685	Δ = -0.155
(N = 14)	↓ P = 1	↓ P = 0.193
60 Hz/2V	Δ = + 0.182	Δ = + 0.0932
(N = 14)	↑ P < 0.05	↑ P = 1

The total power delivered during 60 Hz/2V DBS was equivalent to that delivered during 130 Hz/1.35V DBS. However, their effects on baseline spectral power were significantly different from each other in both the alpha (P < 0.001) and beta (P = 0.006) bands.
