The problem
Intervention: Smartwatch-derived nocturnal scratching metrics using Apple Watch with Itch Tracker application
Who it was tested with: 50 children (median age 9 years) with physician-diagnosed atopic dermatitis.
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"In this prospective observational study, 50 children (median age 9 years) with physician-diagnosed AD wore an Apple Watch with the Itch Tracker application for 5-14 nights during initiation of topical therapy." The study measures scratching before and during treatment initiation to evaluate whether wearable metrics correlate with clinical improvement, but lacks a comparison group and long-term follow-up.
Small sample size, short observation period (5-14 nights), observational design with no control group, cross-sectional biomarker analyses, and measurement only during initial treatment phase limit generalisability and ability to establish predictive validity for long-term clinical use.
