Robot-assisted rehabilitation is becoming an important option in rehabilitation medicine. We utilized one such device, the elbow joint hybrid assistive limb (HAL), for a patient with Guillain-Barré syndrome (GBS). The patient was a 64-year-old man, 16 months post-onset of GBS. Due to severe neuropathy, he was completely dependent on others and unable to eat independently. After approximately two weeks of intensive rehabilitation and self-training following his hospital discharge, he regained the ability to feed himself. This report highlights the effectiveness of HAL in the chronic phase of GBS.
