Detailed Description
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.

Thyroid dysfunction group Subjects with thyroid dysfunction including thyrotoxicosis and hypothyroidism Subjects who were newly diagnosed or undergoing treatment for thyroid dysfunction can be included in the study. Subjects should use a wearable device (Fitbit Inspire 2 TM) and a mobile app (Glandy TM) during the study period. |
Device: Fitbit and Glandy
Data collection from wearable devices (Fitbit Inspire 2 TM) and a mobile app (Glandy TM) Fitbit collects user's heart rate, activity, and sleep data. Glandy collects user's subjective symptom scores.

- Hyperthyroid symptom scale [visit 2: 1-2 weeks after enrollement (visit 1)]
HSS gives scores from 0 to 40, where higher scores indicate more severe disease. It consists of a 10-item scale that rates nervousness, diaphoresis, heat intolerance, motor activity, tremor, weakness, hyperdynamic precordium, diarrhea, weight loss/appetite, and overall function.
- Zulewski's clinical score [visit 2: 1-2 weeks after enrollement (visit 1)]
Clinical scoring system for assessing hypothyroid symptoms and signs (0-12, higher scores indicate more severe)
- Hyperthyroid symptom scale [visit 3 : 4 weeks after visit 2]
HSS gives scores from 0 to 40, where higher scores indicate more severe disease. It consists of a 10-item scale that rates nervousness, diaphoresis, heat intolerance, motor activity, tremor, weakness, hyperdynamic precordium, diarrhea, weight loss/appetite, and overall function.
- Zulewski's clinical score [visit 3 : 4 weeks after visit 2]
Clinical scoring system for assessing hypothyroid symptoms and signs (0-12, higher scores indicate more severe)
- Hyperthyroid symptom scale [visit 4 : 4 weeks after visit 3]
HSS gives scores from 0 to 40, where higher scores indicate more severe disease. It consists of a 10-item scale that rates nervousness, diaphoresis, heat intolerance, motor activity, tremor, weakness, hyperdynamic precordium, diarrhea, weight loss/appetite, and overall function.
