Arm mobility rehabilitation system ALEx RS

robotic

ALEx RS is founded on an innovative design utilizing a novel tendon actuated transmission to provide patients with exceptional comfort, lightweight, and transparency during use. It is a CE certified medical device classified as IIa. The design of ALEx RS originates from the extensive tradition in robotic design established at the Scuola Superiore Sant’Anna and its application in clinical rehabilitation post-stroke. Features ALEx is a six Degrees of Freedom (DoFs) mechanically compliant exoskeleton designed for the upper human limb. The exoskeleton includes four sensorized and actuated joints for shoulder abduction-adduction (SH-Abd-Ad), rotation (SH-Rot), and flexion-extension (SH-Flx-Ext), and elbow flexion-extension (EL-Flx-Ext). Additionally, it features two sensorized and passive joints for forearm pronation-supination (FO-Pro-Sup) and wrist flexion-extension (WR-Flx-Ext). Thanks to its unique shoulder joint kinematics, the exoskeleton is easy to wear and can be adjusted to various anthropometric sizes effortlessly. ALEx can cover approximately 92% of the natural arm workspace, enabling robotic assistance during the execution of natural spatial movements. Benefits Robotic devices offer intensive and high frequency rehabilitation treatment, accompanied by continuous performance monitoring and movement biomarkers to customize treatment levels based on the patient’s requirements. Exoskeleton systems enable precise control over joint movements and articulation torques. ALEx RS can offer guided assistance during intricate upper limb motions, adjusting assistance levels automatically or manually to suit the patient’s needs.
