Feasibility and Efficacy of the Newly Developed Robotic Hybrid Assistive Limb Shoulder Exercises in Patients with C5 Palsy during the Acute Postoperative Phase

Background and Objectives: Although postoperative C5 palsy is a frequent complication of cervical spine surgery, no effective therapeutic rehabilitation approach has been established for palsy. The purpose this study was to find evidence confirming the effectiveness feasibility robotic Hybrid Assistive Limb (HAL) shoulder exercises Materials Methods: In before-after, uncontrolled case series clinical study, we performed mean 11.7 training sessions using HAL immediately after onset in seven shoulders six patients who developed had difficulty raising their during acute phase surgery. Shoulder introduced as early possible evaluating general condition all inpatients Patients underwent abduction on an inpatient outpatient basis at 2-week or 1-month intervals. Adverse events associated with were investigated. angle power without evaluated before usage, every subsequent session, upon completion sessions. Results: Severe adverse due not reported. After sessions, showed improved elevation, while over time. Conclusions: elevation stage potential demonstrate improvement joint function low risk developing severe events.
