Grip strength is hit or miss. I've done it before averaging the force from 5 pulls but if they don't release just right or they get stressed out from you handling them, then that interferes with your results.

Rotorod in our lab is typically done 4 trials per day for 2 consecutive days on an accelerating rod (4-40 rpm). Inter-trial interval of at least 30 minutes. Latency ti fall recorded. Max time is 300 seconds. Always make sure they are facing the right way before beginning acceleration. If they adapt and hold on for 2 rotations around, then take them off (some are clever and won't fall off but ride the rod around).

I've never run treadmill for endurance but you could do it on Rotorod as well at a constant speed.

Good luck!

Thank you Melinda Peters for your kind response

Sorry, I missed the rest of the list! For rotarod, see Rustay et al., PNAS 2003, 100(5):2917-2922.

As @Melinda Peters mentions, the parameters used for rotarod matter a lot, and so does the apparatus itself. This paper explored both accelerated and fixed speed rotarod procedures, in the context of ethanol intoxication vs. baseline and genetic strain differences, another important "parameter." We have found that the diameter of the rotarod matters a lot, and for mice, you can eliminate most of the "riding" behavior if you use a dowel size of 6.5 cm diameter covered with a uniform finish of 320 grit wet-dry sandpaper, with a carefully matched seam, because if the mouse can catch a toe in it, it will ride around and around, which delays latency to fall.
