Evaluation of the Effect of Spry Belt Treatment on Bone Turnover Marker Profile

The Spry Belt is a device worn around the hips which delivers gentle energy to the lower back. The level of energy is controlled by an internal microprocessor (computer) so that it is safe and comfortable. The energy is at a level that may or may not be perceptible to the user. The device is powered by an internal lithium-ion battery which must be recharged periodically. The device is designed to be used with its companion Spry app (via Bluetooth Low Energy (BLE)) so that anonymous usage statistics may be monitored. The expected shelf life of the device is longer than 2 years and the expected use life is at least 12-18 months.

The Sham Spry Belt is a device worn around the hips which does not deliver gentle energy to the lower back. The device instead provides a clicking noise similar to a motor. The device is powered by an internal lithium-ion battery which must be recharged periodically. The device is designed to be used with its companion Spry app (via BLE) so that anonymous usage statistics may be monitored. The expected shelf life of the device is longer than 2 years and the expected use life is at least 12-18 months.
