Abstract

Resistance exercise bands are being incorporated into clinical weight loss programs, particularly for older adults, as resistance training can mitigate the trajectory of muscle mass and bone density loss that can occur while dieting. However, adherence to home-based treatments cannot be reliably ascertained by clinicians as there is no method for clinicians to monitor patient compliance outside of the clinic. BANDPASS, a smart resistance band used for exercise, was developed to bridge the gap between clinicians and patients, allowing for easy remote monitoring of patients’ exercise performance. The device integrates a 10kΩ linear potentiometer to TheraBand® tubing. When the user performs an exercise, the band and potentiometer’s wiper are displaced resulting in a change in voltage which is mapped to the correlated force in kg. A custom PCB and a RedBear BLE Nano are used to wirelessly transmit resistance exercise force data to a smartphone application developed by Dartmouth’s DALI Lab. The final product produces repeatable, reliable and accurate force measurements that can be used to track a patient’s strength.
