About
About Step Doctor
Step Doctor turns an ordinary phone camera into a walking and balance lab, so people, families and clinics can measure mobility at home and follow it over time.
What it measures
Three tests: AI gait analysis (walking speed, cadence, stride, left–right balance and a 0–100 gait score), the Timed Up and Go test with six graded phases (iTUG), and the Short Physical Performance Battery (SPPB), scored 0–12.
