An IoT-enabled omnidirectional mobile system for home-based rehabilitation of upper and lower limbs

Abstract

Robotic systems have made significant strides in stroke rehabilitation, evolving from prototypes to clinical applications. However, challenges remain, including limited clinic accessibility, high costs, bulky equipment, and a lack of versatility for upper and lower limb therapy. Integration into home environments also poses difficulties. To address these issues, we introduce OmniRehab, an innovative home-based rehabilitation system tailored for stroke patients with hemiplegia. OmniRehab combines upper and lower limb rehabilitation on a single omnidirectional platform, supporting both passive and active training modes to accommodate different recovery stages. In passive mode, it provides guided assistance, while in active mode, it promotes voluntary muscle control and neuromuscular re-education. The system leverages Internet of Things (IoT) technology for real-time remote supervision, enabling clinicians to monitor progress and adjust training programs dynamically. To enhance engagement, OmniRehab includes virtual rehabilitation games, offering immersive training that motivates patients while helping them master complex tasks. Experimental validation confirms its effectiveness, demonstrating OmniRehab as a cost-efficient, versatile solution for home-based stroke rehabilitation.
