BACKGROUND: Unilateral hand @entity400 is one of the cardinal symptoms of @entity191 . Additionally, mechanical traumatic hand movement is one of the risk factors for @entity923 . Our objective in this study was to examine whether repetitive mechanical movement may be related to the development of @entity923 in @entity191 with unilateral hand @entity400 using neurophysiological methods. METHODS: The study @entity1 included 33 de novo @entity191 @entity1 with unilateral hand @entity400 , and we compared the @entity400 hand and non- @entity400 hand within the same @entity1 . RESULTS: Seven (21.2%) of the 33 @entity1 had @entity923 . All of @entity923 @entity1 showed @entity854 in both the hand without @entity400 and the hand with @entity400 . In addition, in @entity1 without @entity923 , the sensory nerve action potential was lower in the hand without @entity400 than in the hand with @entity400 , although there were no significant differences. CONCLUSIONS: We concluded that hand @entity400 in de novo @entity191 @entity1 was not directly related to the development of @entity923 . In contrast, more frequent use of hand without @entity400 may induce mechanical loading and may be associated with @entity923 in the hand without @entity400 . Early diagnosis of @entity191 and proper education in hand use may be essential for preventing @entity923 in @entity191 @entity400 @entity1 .
