Nitrous oxide (N2O) is a commonly abused gas that can lead to spinal cord myelopathy. This report details the rehabilitation management of two cases. Both patients experienced lower limb weakness and impaired sensorimotor integration, resulting in difficulty walking. They were treated with vitamin B12 and rehabilitation programs designed using the Rehabilitation Treatment Specification System (RTSS). Both patients achieved independent indoor walking by the time of hospital discharge, with one achieving full function within 9 months. This highlights the effectiveness of combining medical treatment with structured rehabilitation.
Prompt diagnosis of N2O-induced myelopathy and immediate commencement of vitamin B12 treatment are crucial for positive outcomes.
The use of a structured rehabilitation approach, such as the RTSS, can improve the specificity and effectiveness of physical therapy interventions.
Increased awareness of the risks associated with recreational nitrous oxide use is needed to prevent neurological complications.
