Reply To: Alternatives to Hands?
Are you just tapping with your fingers and, of so, does that bother your arms? You asked about tapping with a pen, if you are moving your hands or fingers while holding the pen, that does not bother your arms?
If you are, say, holding a pen in each hand and tapping the pen on a surface, sure, that would work. Or, as you said, yes, you can use your feet instead of your hands as an alternative.
What is important is that you have movement on the right and left side of the body… either hands, fingers or feet.
