Objective：An efficient disaster relief service necessitates the documentation and dissemination of information acquired from disaster response-related activities. However, recording and summarizing information pertaining to rehabilitation support activities is time-consuming and a pressing concern；therefore, mark-sheet forms have been introduced to reduce the time required for this process. Therefore, this study aimed to examine whether mark-sheet forms can facilitate a more accurate and rapid recording of information than conventional descriptive recording forms.Methods：Fifty physical therapists affiliated with the Osaka Physical Therapists Association with no history of performing disaster rehabilitation support activities were recruited. Participants were randomized into descriptive recording form and mark-sheet form groups. Individuals in both groups were instructed to document the information gathered by watching simulated videos of the rehabilitation support activities on their designated recording forms. A statistical analysis compared the accuracy and time required to record the data obtained from the 10 simulation videos between groups.Results：In all 10 scenarios, the recording time was significantly shorter (p＜0.05) for the mark-sheet form than descriptive recording form group. However, no discernible intergroup difference was observed in recorded content accuracy.Conclusion：The use of mark-sheet versus descriptive recording forms facilitated more rapid documentation of disaster rehabilitation support activities.

Osmotic demyelination syndrome is a pathological condition that leads to electrolyte imbalances and rapid correction, resulting in pseudobulbar palsy, quadriplegia, and altered consciousness. Approximately 33-55％ of affected patients experience residual functional impairment. Herein, we describe a case of a patient with osmotic demyelination syndrome who developed locked-in syndrome during the disease course, underwent rehabilitation treatment, and achieved complete remission without sequelae.The patient was a 47-year-old man who was admitted to hospital A owing to weakness in the lower extremities and dysarthria. He had severe hyponatremia and received sodium correction. However, on hospital day 9, dysarthria redeveloped and involuntary finger movements were noted. Osmotic demyelination syndrome was suspected based on the findings of magnetic resonance imaging of the head and clinical course, leading to his transfer to hospital B. Steroid pulse and rehabilitation therapies were initiated at hospital B. By the 19th day of symptom onset, his limb and facial muscle paralysis progressed, leading to locked-in syndrome. Thereafter, the patient was transferred to hospital C, where he received physiotherapy, occupational therapy, and eating training, markedly improving his physical functions. He was discharged from hospital C, 4 months after the symptom onset, with limited range of motion of the fingers and weakness of the extremities and continued to receive outpatient rehabilitation treatment. His symptoms improved further, and 1 year after the onset of symptoms, he returned to work without any sequelae.
