In recent decades, natural disasters have increased markedly. A large-scale disaster can cause not only severe injuries but also stress-related diseases such as cardiovascular events. Particularly, the elderly and persons with preexisting disabilities are at greater risk for injuries, worsening disabilities and deaths in a disaster. The Great East Japan Earthquake 2011 revealed that rehabilitation medicine had some essential roles for people requiring assistance in a large-scale disaster. Firstly, in the acute phase immediately after the disaster, it was important to protect elderly and disabled people from dangerous situations. In this instance, even though significant numbers of vulnerable people requiring assistance remained in the affected area, there were insufficient sheltered locations available, because a large number of medical and welfare facilities were destroyed. Secondly, in the post acute phase after the earthquake, the medical rehabilitation needs for disaster-related disease such as cerebrovascular accidents increased. Finally, in the chronic phase of the disaster, the community based rehabilitation needs to prevent deconditioning syndrome had gradually grown. The aging of the Japanese population is a crucial issue. In this regard, disaster rehabilitation for vulnerable people is similar to comprehensive community care in many aspects. To support disaster victims, the Disaster Acute Rehabilitation Team (DART) and the Japan Rehabilitation Assistance Team (JART) have been proposed to take the lead in disaster rehabilitation. To support these and other ongoing efforts and to better prepare for the future, the Japanese Association of Rehabilitation Medicine and other related rehabilitation professional societies should provide specialized training on disaster rehabilitation.

This report describes a case of an amputee with a lumber spinal cord injury who successfully recovered ambulation with the use of prosthesis.A 30-year-old man with schizophrenia underwent amputation of the lower legs and concurrently developed lumbar spinal cord injury from of a suicide attempt. After the treatment of stump plasty and posterior fusion, the patient was transferred to our facility. Lower-extremity prostheses for both legs were fitted, and orthostatic training was commenced following admission. During the initial evaluation, the patient could not maintain a stable standing position because of weakness in the hip extensor muscle. An inflexion angle of the prosthesis was set to 0° to extend the knee joint and achieve standing stability. Appropriate adjustments of the prosthesis were made as required, specifically addressing the paraplegia caused by his lumbar spinal cord injury. Thus, the patient successfully regained ambulation with the treatment.Recovering walking independence after bilateral lower leg amputations or paraplegia caused by lumber spinal cord injury is not uncommon. However, this case is unique in that the muscle weakness caused by lumbar spinal cord injury presented unforeseen difficulties for the patient to achieve ambulation, which is not ordinarily observed in amputation rehabilitation cases. No similar cases have been reported in which patients concurrently suffered from both these conditions in Japan；therefore, this case is extremely rare.
