How wildly are you flailing? Maybe lighter motions will still do the spin move without hurting you.
On a conventional controller you could rest your arms on your knees while in a sitting position, but standing up with a Wii-mote you have to always have your arms pointing out and that can have a negative impact on me.
You do realize you can sit with the wiimote/nunchuk also right? Infact other than Wii Sports and Guitar Hero* I play all my Wii games sitting down and resting my hands/controllers on my lap.
*I don't understand how people properly rock out sitting down. Just seems wrong.
