Post-Operative physical activity monitoring: algorithm performance and clinical outcomes
NCT ID NCT06605066
First seen Sep 09, 2026 · Last updated Sep 09, 2026
Summary
The goal of this observational study is to validate physical activity algorithms in post-operative populations through raw accelerometer data collection using the ADI Study Watch 4.5 while in an in-patient setting. The secondary objective of the study is to collect skin temperature, photoplethysmography \[PPG\], Bioimpedance Analysis \[BIA\], heart rate \[HR\], SpO2, and electrodermal activity \[EDA\] using the ADI Study Watch 4.5. The main questions it aims to answer are: * Can a wearable physical activity monitoring device assess patients\' activity levels with higher accuracy and precision compared to traditional physical activity monitoring methods during the post-operative period? * Do wearable devices placed on different body regions perform similarly in tracking physical activity during the post-operative period? * Do post-operative physical activity monitoring algorithms improve patient compliance, accelerate recovery, and reduce hospital stay duration? * Analysis of the activity tracking performance of a consumer device (Apple Watch) in patients after cardiac and thoracic surgery.

Inclusion Criteria: * Age ≥ 18, male or female * ASA Score II - III * Patients booked for a surgical procedure requiring general anesthesia care * The subject has had a surgical procedure ≤3 days prior to data collection * Expected duration of general anesthesia to be \> 1 hour * Expected to be transferred to the PACU from the operating room * Patients with an expected duration in the PACU ≥ 45 minutes * Expected to be transferred from the PACU to an in-patient setting * Must be able to understand and provide written consent * Must be willing and able to comply with study procedures and duration Exclusion Criteria: * The subject is unable or unwilling to provide written consent * The subject is unable or unwilling to comply with the study and duration * The subject has not yet recovered from the effects of anesthesia * The subject requires the use of a wheel chair * The subject has been diagnosed with a movement disorder such as Parkinson's disease, ataxia, dystonia, etc. * The subject has not yet recovered from knee or hip surgery * The subject has undergone orthopedic surgery within the last 2 years * The subject has an injury, deformity, or abnormality at the sensor site that in the opinion of the investigators would interfere with the sensors' function * The subject has any other condition, which in the opinion of the investigator would make them unsuitable for the study * The subject is pregnant, lactating, or trying to get pregnant. * Subjects with a history of severe contact allergies that may cause a reaction to standard adhesive materials found medical tape.
