The landscape of mobility aids is experiencing a significant leap forward with the unveiling of the TWIN robotic exoskeleton, specially designed to aid the lower limbs of patients recovering from stroke and spinal cord injuries. The innovative device is a product of the collaborative efforts of Rehab Technologies IIT – INAIL, a joint lab between the Istituto Italiano di Tecnologia (IIT) and the Prosthetic Center of INAIL.
Unveiled in Milan at a press conference at the Museum of Science and Technology, the TWIN exoskeleton represents IIT’s Rehab Technologies Lab’s commitment to developing advanced, cost-effective solutions for those with physical disabilities. With the invaluable assistance of patients like Alex Santucci, who spent considerable time testing the device, TWIN has transitioned from a conceptual prototype to a potentially industrialized product.
The exoskeleton is designed to assist individuals with limited or no mobility in their lower limbs, enabling them to stand, walk with crutches or walkers, and sit down with ease. Its lightweight construction from aluminum alloy and modular design make TWIN unique, offering ease of use and transport. Moreover, it can adapt to various body types with adjustable telescopic links at the femur and tibia and supports different sizes of ankles and feet.
To accommodate varying degrees of motor ability, TWIN can operate in three modes: ‘Walk mode’ for those with no motor function, ‘Retrain mode’ for patients with partial motor function to aid in walking, and ‘TwinCare mode’ for assisting one leg when the other can move autonomously. Controlled by a physiotherapist through a dedicated Android application, the exoskeleton can adjust walking patterns in terms of step length, type, and speed.
Patients in rehabilitation facilities can benefit from regular use, and even a few hours of daily wear can significantly enhance musculoskeletal, circulatory, psychological, and digestive functions. Following anticipated CE marking and subsequent industrialization, TWIN aims to be a remarkable tool for reintegrating individuals with severe injuries back into society and work.
As the TWIN exoskeleton approaches the final stages before market release, the promise of enhanced quality of life for patients suffering from stroke and spinal cord injuries draws nearer, heralding a new era of empowerment for those affected by mobility impairments.
