Обзор

Development of a soft robotic device for rehabilitation and assistance of the upper limb for people with neurological disorders (FRONTIER)

Подробное описание

Wearable robotics is a rapidly expanding field, with robotic devices increasingly being explored and integrated into neurorehabilitation practice. Robotic exoskeletons based on motor learning principles have been introduced to support rehabilitation interventions and are available in a wide range of configurations, including soft or rigid architectures, systems with single or multiple degrees of freedom, and devices targeting either the upper or lower limbs.

In this context, FRONTIER aims to develop, integrate, and evaluate a soft robotic exoskeleton designed to support upper-limb motor function in individuals with chronic neurological impairments resulting from acquired brain injury (ABI). The device is intended to assist both isolated and coordinated multi-joint movements involving proximal upper-limb segments, including the shoulder and elbow, and distal segments, including the hand.

The primary objective of FRONTIER is to evaluate the clinical usability of the soft robotic exoskeleton prototype, which integrates existing robotic modules, and to support the development of synergistic control algorithms coordinating assistance across multiple upper-limb joints. The study will evaluate the usability, safety, and acceptability of the system during a single testing session in a clinical rehabilitation setting. The findings will provide preliminary information to guide further development and future evaluation of the device in neurorehabilitation.

Вмешательства

• Устройство FRONTIER Soft Exoskeleton
  Each participant (both healthy volunteers and patients) will take part in one single testing session, structured as follows: 1. Unassisted condition: subjects will perform a set of standardized upper limb movements (shoulder, elbow, and hand) without robotic assistance. 2. Assisted condition (robot active): the same set of movements will be repeated with the support of the FRONTIER exoskeleton.
