Sorry, I didn't realize it would be so hard or elusive for you to substantiate what you're saying. 😉
Ok, you are obviously unwilling to use Google or similar search engine. Lets limit the links to actual studies or reviews of actual studies, not someone claiming (1) the keyboard solved all the worlds problems or (2) the keyboard did nothing.
So here are the first few unfiltered Google links I got for the most common problem which is mistakenly associated with keyboards, carpal tunnel syndrome (CTS):
June 11, 2003 issue of the Journal of the American Medical Association "researchers found that using a computer keyboard repetitively was not associated with developing CTS symptoms. Interestingly, time spent using a computer mouse did increase the risk of having CTS symptoms among participants in this study."
One year follow up study to the JAMA study"No statistically significant association with keyboard use"
Harvard Medical School Review of Literature"although people using computer keyboards has provoked much publicity about their risk for carpal tunnel syndrome, it is actually lower than those in occupations involving heavy labor". "One study observed that typists with carpal tunnel syndrome struck the keys with greater force than those without the disorder" Again, it is how you use the keyboard, not the type of keyboard.
Neuroland information on CTS for health card professionals "Keyboard use as cause of CTS is not confirmed by study".
Mayo Clinic Study"Using Computer Doesn't Increase Risk Of Carpal Tunnel Syndrome." "These percentages are similar to percentages found in other studies looking at how often carpal tunnel occurs in the general population -- not just computer users" . "The researchers also found no significant differences between the computer users who had carpal tunnel and those who did not." Conclusion: rate of occurance of CTS in computer users is the same as non-computer users.
