[Electromyographic performance of the lower arm musculature in the spastic patient before and after transplantation of the m. flexor carpi ulnaris (author's transl)].
Quantitative electromyographic studies of the lower arm musculature before and after distal displacement of the flexor of the hand and digital flexor as well as transplantation of the m. flexor carpi ulnaris to the dorsal side of the wrist joint were conducted in 10 patients with a spastic hand. At the same time the absolute force during isometric flexing and stretching was also recorded. The results revealed that the reciprocal innervation in the paretic antagonist improves, and the efficiency of the muscle is enhanced, by the surgical relaxation of the contracted agonist. The flexor carpi ulnaris transplanted to the dorsal side will additionally safeguard the muscular balance between flexors and extensors modified towards approaching the standard values. However, the transplanted flexor does not undergo a "learning" process in cortical level in the sense of performing the tasks of an extensor.
