An algorithm to predict thyroid dysfunction using heart rate and activity data from wearables was generated based on our previous clinical studies. This study was conducted to collect more data to advance the algorithm.~Patients with thyroid dysfunction including hypothyroidism and thyrotoxicosis were eligible for this study. During the study period, each subject wears a smart band (Fitbit Inspire 2 TM) and gets 3 times of thyroid function tests with 1-month interval. Study participants will use a mobile app (Glandy TM) to collect the symptom scores.
This study is a single center observational study to investigate the association between biosignals from wearables and thyroid dysfunction.
