Desarrollo de una órtesis para rehabilitación de hombro con dos grados de libertad de uso domiciliario

Limitations in upper limb movement due to pathologies or accidents can significantly impact a person's daily life, affecting their social, economic, and professional activities. This underscores the importance of rehabilitation, which, through consistent therapies, can effectively aid in the recovery process. However, traditional rehabilitation often relies on large supportive devices, necessitating visits to care centers. Unfortunately, inconsistent attendance can lead to slow or even nonexistent progress. To address this, portable active orthoses have emerged as a potential solution, offering the possibility of faster recovery. In this study, an additional degree of freedom (flexion extension of the shoulder) was integrated into an orthosis previously developed at the University of Santiago de Cali, tailored for upper limb rehabilitation in individuals with limited shoulder movement. The implementation involved redesigning the device, updating electronic components for improved ergonomics, and incorporating a linear motor. The device underwent evaluation with 15 participants performing shoulder flexion-extension movements from rest to 70, yielding an acceptability rating of 75.6 out of 100 using the system usability method
