摘要：Traditional Shotokan Karate training requires hand conditioning using the Okinawan traditional padded punching board, the “makiwara ”(maki -“roll up ”or “wrap”, and wara- to “straw”). Karate practitioners used to work out for hours with this device, to toughen the hands and strengthen the wrists to be able to deliver more powerful hand techniques. However, even though they may not use a makiwara, modern karatekas practice their karate strikes on sandbags. This training may produce different injuries (Adams and Mutasim, 2001; Vayssairat et al., 1984). Crosby (Crosby, 1985) radiographed the hands and wrists of 22 karate instructors, 17 of whom punched regularly the makiwara and performed pushups on the knuckles every day. He concluded that zealous use of the makiwara was a cause of pain and stiffness in the hands and wrists, but neither practice had a consistently deleterious effect on the mobility of the index and middle fingers metacarpo- phalangeal joints which bore the brunt of the impact.
