Epidemiologic changes in nontraumatic spinal cord injury for the last 30 years (1990-2019) in South Korea.

The proportion of NTSCI among total spinal cord injuries has increased in Korea over the last 30 years (1990-2019). Compared to individuals with TSCI, those with NTSCI had a higher age at onset, with different male-to-female ratios. Our study is the most comprehensive investigation of NTSCI in Korea, and our findings can inform research directions and medical guidelines.
