Physical therapists master manual examination techniques for testing impaired motor functions. We developed a wearable robotic dummy joint to simulate disordered joint resistances for supporting physical therapists to learn such techniques. We implemented 5 symptoms seen in knee joint diseases and strokes. The implemented models were validated based on the introspection of physical therapists, and some simulated resistances well matched with their experiences. The symptom models and dummy joint have been continuously undergoing improvement cycles.
