Skin temperature (surface and muscle; biceps·brachioradialis the ring finger) and plethysmograph on the forefinger is recorded before and after stellate ganglion block in five stroke patients with post-hemiplegic shoulder-hand syndrome under the artificial weather room (temperature 30°C, humidity 60%).The results obtained can be summarized as follows, (1) plethysmographic pulse wave height of the affected finger is indefinite before and after stellate ganglion block.(2) skin temperature is not always elevated after the stellate ganglion block.Therefore it is suggested that there is abnormal peripheral hemodynamics and the effect on stellate ganglion block is dependent not only on the efferent (sympathetic fiber) interruption but also on the afferent one.
