Abstract: A person's mobility and freedom can be severely impacted by neurological conditions like stroke, spinal cord injury, and traumatic brain injury that cause lower limb weakness or paralysis. For these patients, rehabilitation is crucial to regaining muscular function and enhancing mobility. Controlled electrical pulses are used in Functional Electrical Stimulation (FES), an efficient rehabilitation method that helps strengthen weak muscles and facilitate movement. In order to enhance rehabilitation results, this study suggests a Multimodal Sensor-Based FES Device for Assisted Lower Extremity Movement that integrates various sensing technologies. The device incorporates plantar pressure sensors to examine the distribution of foot pressure during movement, an EMG sensor to track muscle activity, and a goniometer sensor to evaluate joint angles and range of motion. The patients physiological and biomechanical data is continuously gathered by these sensors and sent to a microcontroller for processing. The method ensures more efficient and flexible rehabilitation by controlling the electrical stimulation applied to the target muscles based on the collected data. Better evaluation of patient development is made possible by the introduction of multimodal sensors, which offer detailed information about muscle function, limb movement, and weight distribution. The suggested gadget aids in preventing issues including poor blood circulation, joint stiffiiess, and muscle atrophy that are linked to extended immobility. Additionally, it provides individualized therapy based on the patient's condition and encourages active engagement in rehabilitation exercises.

Additionally, it provides individualized therapy based on the patient's condition and encourages active engagement in rehabilitation exercises. The device is appropriate for both clinical and home-based rehabilitation settings due to its portability and user-friendly design. The suggested device seeks to improve lower extremity movement, improve functional recovery, and improve the overall quality of life for those with neurological impairments by combining aided muscle stimulation with real-time monitoring.
