This study is looking at whether regular insulin, given as a nasal spray, is safe for people who have had a spinal cord injury. While insulin nasal spray has been found safe in other groups, it hasn't been studied in individuals with spinal cord injury yet. This research is a first step to see if this could be a future treatment. We are recruiting up to 12 adults, aged 18 to 84, who experienced a spinal cord injury at least four months ago. Participants will use either the insulin nasal spray or a placebo (an inactive nasal spray) at home daily for up to 24 days. The main goal is to track any serious side effects or other side effects to understand the safety of this treatment.
