Biomechanical Assessment of Post Stroke Patients’ Upper limb Before and After Rehabilitation Therapy Based on FES and VR

Background: Stroke is a medical condition characterized by the rapid loss of focal brain function. Post-stroke patients attend rehabilitation training to prevent degeneration of physical function and improve upper limb movements and functional status after stroke. Promising rehabilitation therapies include Functional Electrical Stimulation (FES), Exergaming, and Virtual Reality (VR). Methods: This work presents a biomechanical assessment of 13 post-stroke patients with hemiparesis before and after rehabilitation therapy for two months with these three methods. Patients performed two tests (Maximum Forward Reach and Apley Scratching) where maximum angles, range of motion, angular velocities and execution times were measured. A Wilcoxon test was performed (p = 0.05) to compare the variables before and after the therapy for paretic and non-paretic limb. Findings: Significant differences were found in range of motion in flexion-extension, adductionabduction, and internal-external rotation of the shoulder. The increase found was flexion-extension 17.98% and internal-external rotation 18.12% after therapy in the maximum forward reach test. For shoulder adduction-abduction, the increase found was 20.23% in the Apley scratching test, supporting the benefits of rehabilitation therapy that combines FES, Exergaming, and VR in the literature.
