Customer Physical Therapy Clinic at Nazareth College J.J. Mowder-Tinney, PT, MS, NCS, CWS Project Timeline Key Objectives 1. Design a mechanical system that mimics the lateral movements of a traditional bicycle. 2. Design and implement a control system to enable variable resistance of bicycle leaning characteristics. 3. Provide feedback to the patient and PT to indicate specific angles at which balance requires correcting, or imminent tip over conditions are present.
