Abstract
Seasonal change of the finger tip pulse wave responsive to language stimulation (instruction) was observed among 28 subjects for fall (September), winter (December), spring (March) and summer (July) in that order. The selected 28 subjects were 21 remote hemiplegic male of 6th and 7th decade (14 right hemiplegics and 7 left hemiplegics) and 7 normal male of the same age group.
The following findings were obtained;
1. The fingertip pulse wave among the normals showed marked lowering in fall under language stimulation (instruction) and reading showing W-type pattern.
2. Among the hemiplegics when given language stimulation the lowering of the pulse wave did not recover in one minute showing tension state longer than the normals. The recovery after reading was as fast as the normals.
3. The tension caused by language stimulation seemed stronger in right hand than left and seemed to last longer. This tendency was similar in both the normals and hemiplegics.
4. Right hemiplegics were observed in 2 groups with or without speech disturbance. There was no basic difference and common response pattern as right hemiplegia was observed.
5. Among the left hemiplegics lowering of the pulse wave under language stimulation was not recognized in fall both on right and left side and there was no lowering on the unaffected side under reading. This response was different from that of the right hemiplegics.
6. Judging from the fact the hemiplegics showed W-type pattern and the normals did not in spring, it was presumed that altering rhythm of the sympathetic function in a year might be changing among the hemiplegics. However, this might be due to the factor that only the in-patients were selected as subject for this particular study.
