Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: QUADRUPLE
• Who Masked: PARTICIPANT, CARE PROVIDER, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: Devices are assigned per the randomization schedule, with the sham device identical to the active device in every way except that no neuromodulation is delivered. The neuromodulation that the active device delivers can be done in a way that causes no sensation, so subjects are not unmasked.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: INDUSTRY
• Responsible Party: SPONSOR

Model Details: Double-blind, randomized, sham controlled study
