Electromyographic investigations by evoked method were performed on 23 patients of cerebral palsy aged from six to sixteen male and female. 14 patients of them are spastic type, 3 are ataxic, and others are mixed.The H wave was recorded from calf muscle following stimulation of the posterior tibial nerve in the popliteal fossa.The results of the repetitive evoked electromyography and recovery curves were compared with normal ones.On repetitive evoked method, in both low and high frequency, the H wave schowed high amplitude and undulations in many cases.In high frequency, 20 cps, spastic, ataxic, and mixed type seemed to schow different patterns.The recovery curves vary much in many cases.To observate the effect of the drugs, Diazepam and Chlormezanon, two patients of spastic type were selected. Diazepam (6mg per day) was given to one, Chlormezanon (3 tab. per day) was to another for one month. The recovery curves before and after medication were compared.
