Abstract
After receiving a coronary bypass surgery, patients are required to limit their range of motion to prevent re-injury, of which non-adherence can result in sternal dehiscence, wound site infection, emergency surgery, and prolonged rehabilitation. This need is exacerbated by non-adherence at home, the demand to reduce time spent in hospital/post-acute care, and the increased risks associated with improper rehabilitation Our product aims to measure and provide real-time feedback on patients' range of motion to improve rehabilitation outcomes. Our IPDT aims to utilize Inertial Measurement Unit (IMU) motion tracking technology to capture patient motion. IMU sensors contain magnetometers, accelerometers, and gyroscopes to extrapolate three-dimensional position, linear and angular velocity, as well as linear and angular acceleration. IMU sensors are used in sets on the human body to measure three dimensional biometric motion, such as joint angles and joint velocity. They can be purchased 'off the shelf' for a reasonable cost, and IMU sensors are already utilized widespread in the market for high-end athletic performance metrics. IMU sensors are utilized in medical rehabilitation as well, though it is slower to market and its use not as wide-spread. The CABG (coronary artery bypass surgery) industry alone will experience a 5.6% CAGR (compound annual growth rate) [13], which is the major contributor to sternotomy rehabilitation patients. Insurance companies aim to reduce time patients spend in medical facilities after surgery, and COVID 19 has affected how long these patients are able to stay in medical facilities after a procedure. Our IPDT believes our device can serve to prevent the numerous related costs to insurance companies caused by patient re-injury and improve patient recovery.
