Hello.
I am not sure to be at the right place but I have a biomechanics question. I am a visual psychophysicist and I have been looking for a number for a few years without being able to find it in the literature: I would like to know how long it takes for the fingers to press a key once the impulse received. I know that this latency has been measured for the extensor digitorum (where observers had to stop pressing a key to answer), but I haven't been able to find it for the flexor digitorum. So I ended up measuring it myself with surface EMG and found fairly similar latencies as for the extensor (what a surprise...), i.e. between 40 and 50ms. But still, I would like to know if that number has been measured by someone else.
Would you know if this number has been measured and where to find it? If not, do you know why no one has measured it before? Is it only because the flexor digitorum is more difficult to record than the extensor? Are there reasons not to trust this estimation (artifacts etc)?
Thanks a lot.
Regards,
Baptiste
