For this purpose, advanced biomechanical analysis techniques are used to evaluate: <\/p>\n\n<h3 class=\"wp-block-heading\">Three-dimensional kinematics of motion<\/h3>\n\n<p><br\/>The 3D capture systems record limb trajectory, gait symmetry and joint amplitude, detecting possible compensations or restrictions induced by the exoskeleton.<\/p>\n\n<h3 class=\"wp-block-heading\">Dynamics of forces and joint moments<\/h3>\n\n<p><br\/>By means of force platforms and inertial sensors, the loads transmitted to the joints are quantified. This is essential to avoid overloading the knee, hip or lumbar spine. <\/p>\n\n<h3 class=\"wp-block-heading\">Muscle activity by electromyography (EMG)<\/h3>\n\n<p><br\/>EMG analyzes which muscles are activated when the user uses the exoskeleton, making it possible to determine:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>if there is adequate assistance to the movement,<\/li>\n\n\n\n<li>if muscle fatigue is reduced,<\/li>\n\n\n\n<li>or if the exoskeleton induces undesired activation patterns.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Assessment of motor control and postural stability<\/h3>\n\n<p><br\/>The exoskeleton algorithms must respond to variations in the user&#8217;s balance. Postural analysis makes it possible to validate the accuracy of these control systems in the face of real disturbances. <\/p>\n\n<p>These techniques not only provide essential data for <strong>clinical safety<\/strong>, but also allow manufacturers to optimize the design of the exoskeleton, adjust assistance algorithms and improve the comfort and reliability of the system. At Med-Lab IBV, this evaluation is carried out in an environment equipped with motion analysis technology of international reference, integrating all biomechanical parameters in interpretative reports that facilitate certification under MDR. <\/p>\n\n<p>More information in our <a href=\"https:\/\/med-lab.ibv.org\/en\/exoskeletons\/\"><strong>exoskeleton testing laboratory<\/strong><\/a><\/p>\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Exoskeletons for rehabilitation have become a key tool for patients with spinal cord injuries, stroke or musculoskeletal pathologies.
