MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641021584 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Feb. 24, for 'electromyography based motor intention - execution gap gait sensor system.'
Inventor(s) include Premson A; Kotteeswaran K; and Dr. Deepak Nallaswamy Veeraiyan.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an electromyography-based Motor Intention-Execution Gap (MIEG) gait sensor system for objective assessment of human ambulation. The system comprises one or more surface electromyography (EMG) sensors configured to capture neuromuscular activation signals representing motor intention, and at least one inertial measurement unit (IMU) configured to record limb motion corresponding to motor execution during gait. The acquired EMG and motion signals are processed by a data processing unit to generate predicted movement parameters from EMG activity and actual movement parameters from IMU data. A novel algorithm computes a Motor Intention-Execution Gap index by quantifying temporal, magnitude, and pattem discrepancies between the motor intention and the executed movement across the gait cycle. The calculated gap index is utilized to identify and classify gait control deticits, ditTerentiate neural and mechanical impairments, and monitor functional recovery over time. The system further provides real-time or post-processing diagnostic output and feedback through a display or wireless interface. The proposed invention offers a wearable, non-invasive, and clinically meaningful gait assessment tool with applications in neurological rehabilitation, musculoskeletal assessment, physiotherapy, and home-based gait monitoring."
