Wearable Device Guided Exercise for Patients on Total Knee Arthroplasty Wait-list
The Application of Wearable Device Guided Pre-operative Exercise Programme for Patients Awaiting Total Knee Arthroplasty: A Randomized Controlled Trial
Total knee arthroplasty (TKA) is a cost effective solution for people with end-stage knee osteoarthritis. Given Hong Kong's large senior population and age as the primary risk factor for osteoarthritis, waiting times for total knee arthroplasty can reach 30 months. To manage this long wait list, patients would be enrolled to a structured exercise program with group and home based exercise. Currently limited options are available for home based exercise adherence monitoring for TKA patients on the wait-list. This study will assess the effect of wearable device with smartphone application to guide home based exercise among these wait-list patients. The main hypothesis is that the use of wearable device will decrease patient's pain level and improve their physical activity level.

Detaillierte Beschreibung
All participants will consent that their anonymized data will be collected and used for scientific publications in accordance to the declaration of Helsinki. Patients on the wait-list for primary TKA at Prince of Wales Hospital in Hong Kong would be recruited and randomized to either wearable device or control group with measurements done at baseline, six weeks and six months post intervention. Control group received standard training intervention and follow up schedules, while the wearable device group would receive the wearable device and associated smartphone application along with familiarization training over the first six weeks of training.
