本研究針對國內空手道現役選手，探討手部神感覺的差異，受試者分為二組，分別為空手道組和一般組，測試儀器是利用單一纖維細絲、捏力計、握力計等三套儀器進行實驗，其實驗測試順序為單一纖維細絲、握力計、捏力計，在單一纖維細絲方面，測試部位為五個手指之掌尖及手背掌指連結處，共計九個部位，測試結呆發現空手道組之左手手背無名指近端為0.38±0.15，一 般組為0.24±0.I7g(p<.05) ，而在右手手背中指端部分，空手道組為3.5±5，一般組為0.30+ 0.I4g(p<.05) ，空手道之觸壓覺顯著地差於一般組。而在握力測試方面，空手道組左手握力40.27±8.07g，一般組為49.32±6.26g，空手道主且右手握力39.85 + 6.28g，一般組為46.78 + 7.14g， 測試結果發現空手道組的握力明顯地小於一般組。而在拉力方面，二組並無顯著差異。

The study was to investigate hands nerve sensibility for karate competitors. Subjects were classified as two groups including EXP group (karate competitor)and CON group (normal healthy subject). We evaluated the cutaneous tactile sensitivity by using monofilament wire test. Theresult shows that monofilament index score in two of nine test regions was significantly higher in EXP group (posterior proximal left ring finger : 0.38 + 0.15 g; posterior proximal right middle finger : 3.5±5 g) than in CON group (0.25 + 0.17 g and 0.30±0.14 g). In addition， grip test showed that force score (lefthand: 40.27±8.07 Kg， right hand: 39.85±6.28 Kg) was significantly lower in EXP group compared to CON group (49.32±6.26 Kg and 46.78 + 7.14 Kg). However， no significant difference was found between groups in pinch test.
