What is selective dorsal rhizotomy (SDR)?

Selective dorsal rhizotomy (SDR) is a surgical procedure that helps reduce muscle tightness in children with spasticity, a prominent feature of cerebral palsy. Spasticity happens when certain nerves send too many excitatory signals to the muscles, causing them to be stiff, tight and hard to control. During SDR, the surgeon carefully cuts specific nerves in the spine that are causing muscle tightness. This allows the muscles to relax and move more freely.

After SDR, many children find it easier to walk, sit and stand as well as use assistive devices. While SDR doesn't help every child walk independently, it can help them move with less pain and effort.

SDR is not a cure for cerebral palsy. However, when combined with physical therapy, it can significantly improve your child's comfort, movement, and overall quality of life – both now and in the future.
