Cura adopts positive conditioning to minimise the chance of lesions occurring, caused by scratching during sleep. A ring is worn by the user and a base unit is clipped onto or place near the pillow.

When the ring detects scratching patterns, a wireless signal triggers the base unit, causing it to emit a low frequency sound. This raises the user to stage two of sleep, and within four weeks (one Pavolo conditioning cycle) this will stop harmful scratching habits.
