Study Arms:
- Aerosure 15 Hz (Type: EXPERIMENTAL): All subjects receive an active device operating at a specific frequency, active device operating at another specific frequency and sham device (disabled):~Aerosure at 15 Hz; Aerosure at 25 Hz; Sham Aerosure. Order of presentation is randomised.
- Aerosure 25 Hz (Type: ACTIVE_COMPARATOR): All subjects receive an active device operating at a specific frequency, active device operating at another specific frequency and sham device (disabled):~Aerosure at 15 Hz; Aerosure at 25 Hz; Sham Aerosure.
- Aerosure sham (Type: SHAM_COMPARATOR): All subjects receive an active device operating at a specific frequency, active device operating at another specific frequency and sham device (disabled):~Aerosure at 15 Hz; Aerosure at 25 Hz; Sham Aerosure.

Based on this trial design, predict the completion outcome and termination type (if applicable).
