Paralyzed Veterans of America: PVA Publications -- Expected Outcomes: What You Should Know
This series of eight guides describes outcomes according to level of spinal cord injury (C1-3, C4, C5, C6, C7-8, T1-9, T10-L1 and L2-S5). Each guide provides individual guidance on what people with different levels of SCI can reasonably expect to do for themselves one year after injury; what help will be needed with daily life tasks at home, at work, and in the community; and what equipment can help make a person with SCI more independent. This information can help people with SCI and those who care for them to understand the present and plan for the future.
