 Also, from at least the 1950s through at least the 1980s, there was a strong focus on other interventions for spastic muscles, particularly stretching and splinting, but the evidence does not support these as effective.While splinting is not considered effective for decreasing spasticity, a range of different orthotics are effectively used for preventing muscle contractures on patients with spasticity.In the case of spastic diplegia there is also a permanent neurosurgical treatment for spasticity, selective dorsal rhizotomy, that directly targets nerves in the spine that cause the spasticity, and destroys them, so that the spasticity cannot be activated at all.
