The first experience of exoskeleton rehabilitation in a patient with extensive ballistic upper arm injury during the use of temporary cement humerus spacer

This study aimed to evaluate the initial experience of utilizing the passive upper extremity exoskeleton "Ekzar34" in the rehabilitation process of a patient with upper extremity ballistic injuries, in conjunction with the use of a temporary cement spacer in the shoulder bone. Methods: The research methods included a clinical examination of the patient, analysis of medical records, X-rays, and goniometry of upper extremity joints before and after the rehabilitation course in the "Ekzar34" exoskeleton. Results: The results demonstrated a significant increase in the amplitude of active and passive movements, as well as muscle strength in the affected limb. Moreover, there was a decrease in pain during movement with the rehabilitation using the exoskeleton. Conclusions: The initial experience of utilizing the upper extrem-ity exoskeleton "Ekzar34" in extensive upper arm ballistic injuries during the recovery stage with the application of a temporary humerus spacer appears promising in post-ballistic injury rehabilitation. Following the removal of the tempo-rary spacer and shoulder bone reconstruction, continued use of the exoskeleton is deemed essential for enhanced func-tional rehabilitation of the patient. This study emphasizes the significance of a comprehensive approach to the rehabilita-tion of patients with extensive upper extremity ballistic injuries and confirms the effectiveness of using the "Ekzar34" ex-oskeleton at all stages of treatment.
