Figure 2. Suppression of aberrant urethral reflexes after chronic SCI.

Figure 2

Representative examples of aberrant urethral reflex activity with and without dermatome stimulation. All panels: Sacral root stimulation (20 Hz, solid bar) was applied to directly evoke bladder pressure and provoke DSD in a consistent, repeatable manner. Panel A: Control trial showing baseline reflex activity. Panel B: The addition of patterned electrical stimulation to the sacral dermatomes (.75 ON .25 OFF, 20 Hz, dashed bar) suppressed the aberrant EUS reflexes. Panel C: Applying dermatome stimulation to the same electrode with different stimulus pattern (.5 ON .5 OFF, 20 Hz, dashed bar) did not significantly reduce urethral activity. This parameter space specificity is representative across both responder animals.
