Comparison of AI-based Smartphone-derived Gait Parameters With the Gold Standard
This study is testing whether AI-powered smartphone apps can measure how people walk just as accurately as a high-tech motion-capture lab system. Researchers will ask 40 healthy adults to walk while carrying iPhones and Android phones in their pockets, while a professional Vicon camera system records the same movement simultaneously. This is a Phase NA validation study — it is not testing a treatment, just checking whether a low-cost tool matches the gold standard.
You may qualify if
- Adults aged 18 years or older. No known acute or chronic disorder or injury of the lower extremities. Ability to walk independently. Sufficient physical capacity to complete a standardized walking test. Ability to understand the study information and provide written informed consent. German-, English-, or Spanish-speaking.
You're excluded if
- Acute injury or disease of the lower extremity. Chronic injury or disease of the lower extremity. Inability to walk independently. Relevant motor impairment or other major limitation affecting safe gait testing. Lack of capacity to provide informed consent. Inability to understand German, English, or Spanish. Insufficient physical capacity to perform the walking test. Any condition that, in the opinion of the study team, would impair participant safety or the validity of the gait measurements.
