Self-management of Post COVID-19 Syndrome Using Wearable Biometric Technology

The main objective of this pilot study is to evaluate the impact of a self-management intervention using wearable biometric technology on post-COVID-19 syndrome. In addition, this pilot-study will provide information regarding validity, feasibility, patient compliance and satisfaction, valuable for the design of a future large-scale study.

This pilot-study uses a one-group before-after design. Subjects: a convenience sample of 20 adults 18 years and older in the Winnipeg Health Region with a post-COVID-19 infection (≥ 3 months since acute infection) complaining of mild to severe persistent respiratory symptoms. Intervention: using the participants' initial assessment, personal characteristics, main complaints/needs and goals, the therapist will adjust the exercise plan and personalize the recommendations (e.g. maximum heart rate) as well as instruct the patients about safety precautions (how to pace themselves, when to seek professional or emergency care). Participants will be encouraged to wear the smart shirt as much as they want during the 6 weeks (29), but at a minimum of 1-hour a day (M-F) including while performing the recommended exercises (30-45 min/3 times a week). They should self-monitor their biometric values trying to reach/stay within the target values while wearing the shirt using Hexoskin app installed on an iPad provided by the research team or on the participants' personal device if preferred. Patients will also complete an online survey reporting symptoms intensity and activities completed, 3 times a week (over 6 weeks). Participants would be able to contact the research assistant overseeing the intervention at any time of the study if they have questions or concerns (text message or email). Otherwise, they will receive a follow-up phone call every week or if a significant change in their biometrical data is identified.

It will be assessed using a SpiroBank Smart F/V multi parameter spirometer (MIR) at pre-post intervention and once a week in between to monitor changes. This portable spirometer, which is MDSAP approved and complaint with ATS/ERS guidelines, connects automatically via Bluetooth to an iOS & Android compatible App (MIR Spirobank). It provides real time feedback through messages and animation on smartphone, to improve personal compliance during the test. The app can generate test results PDF printout with information regarding 19 parameters of lung capacity.

Participants will be ask to rate their symptoms from 0-10 using an online form (base on the baseline symptoms)

Participants will complete a short summary with questions regarding their satisfaction with the study
