Innovative health monitoring for wheelchair users: A scoping review of smartwatch applications

This study aimed to review the application of commercial smartwatches as a tool for monitoring health and exercise variables and the accuracy of their measurements, with users being people with physical disabilities who use manual wheelchairs. The searches were conducted in PubMed, Scopus, Web of Science, and IEEEXplore. Studies were included regardless of experimental design as long as they involved people with physical disability or without any physical disabilities who used manual wheelchairs in evaluations with commercial smartwatches. Thirteen studies were included in the review. Overall, there was no consensus on the accuracy of wheelchair-related measurements, such as physical tests and daily activities, with only the Apple Watch® Series 1 and 4 and the Fitbit Charge 2® providing acceptable information. Regarding the physiological measurements offered by smartwatches during physical evaluations, only the Xiaomi Mi Band 5® provided reliable heart rate readings. Additionally, the Apple Watch® Series 5 did not demonstrate sufficient sensitivity to detect falls from the wheelchair. Finally, despite these limitations, commercial smartwatches are seen as a promising tool for self-care and increased autonomy. However, restrictions must be considered, especially in contexts where movements are subtle or gradual, and they should not be used for clinical purposes or disease diagnosis.
