Poor Patient Compliance Hinders Study of Validated Wearable Devices

Sleep deprivation is one of the most common symptoms observed in shoulder surgery patients, both before and after surgery. This symptom reduces pain tolerance which can negatively impact patient rehabilitation. That’s why it’s important to monitor sleep patterns and sleep disturbances to better understand the drivers of postoperative fatigue and pain.

According to the American Academy of Orthopedic Surgeons, about 53,000 people in the U.S. have shoulder replacement surgery every year. These surgeries relieve pain and help patients resume daily activities. VWDs are increasingly being used to monitor sleep metrics after orthopedic procedures. Heart rate, resting heart rate and heart rate variability (measured by VWDs) determine sleep stages. In this study, a WHOOP 2.0 Strap was used to measure sleep duration, assess four-stage of sleep against a high-level sleep study as well as two-stage sleep against high-level sleep disorder assessments. PROs were collected with the aid of three validated outcome survey questionnaires: Patient-Reported Outcomes Measurement Information System Physical Function, American Shoulder and Elbow Surgeons self-evaluation, Disabilities of the Arm, Shoulder and Hand and a visual analog scale.
