Abstract
Patients (26) were operated on using a technical modification of Foerster''s method of treating spasticity, which consisted of a partial section of the rootlets constituting the posterior roots. Many patients had mild cerebral spastic quadriplegia or spastic diplegia; several of them were nearly independent when standing or walking, and 2 of them were completely independent. The spastic disorders that were not made worse by voluntary movements were reduced or abolished in all but 1 patient, in whom rootlet section was insufficient. The spastic disorders that were made worse by voluntary movements were only partially reduced; after operation they were scarcely evident or absent in a static position, but evident during voluntary movements. No improvement was observed in 1 patient who suffered from spastic disorders that were evident only during voluntary movements, or in 1 patient suffering from dystonia. The procedure caused no sensory disorders. The operation was especially useful in patients who were acquiring or had already acquired independence when standing or walking.
