I just discovered today that there are some tiny muscles directly in the hand itself (apart from the obvious adductors). I had previously thought that almost all hand movement was produced by muscles in the forearm, but apparently these little muscles are used, too. It appears that development and coordination of these small muscles can be very useful in playing the piano. That led me to wonder if they might also assist in typing, either with improving speed or with improving accuracy. Also, it seems to me that if these muscles can be favored when typing, the incidence of wrist-related RSI could be greatly reduced. What do you all think? Has anyone done research on this? Are there practical exercises that could be used to favor the use of these muscles when typing so as to improve typing performance and accuracy and reduce the risk of RSI? -- Transpose hotmail and mxsmanic in my e-mail address to reach me directly.
