The Welgain rehabilitation sensor system represents a significant advancement in physical therapy by introducing objective motion tracking to a field traditionally dependent on subjective practitioner assessment. This compact wearable technology was developed by former Toyota rehabilitation robotics engineers.

The Welgain rehabilitation sensor system utilizes multiple body-worn sensors containing accelerometers, gyroscopes, and wireless communication capabilities to quantify patient movements with precision. At Fujita Health University Hospital, clinicians have implemented the system to provide real-time auditory feedback during exercises, generate 3D movement visualizations, and create comparative progress records. These tech advancements are intended to address longstanding challenges in treatment standardization and patient self-monitoring.

The case study of stroke survivor Akihiro Kurokawa demonstrates the Welgain rehabilitation sensor system’s practical effectiveness, where the innovation’s immediate feedback corrected compensatory movements that might have caused secondary injuries during his recovery.
