Hi BB,

Imbalance of the foot muscles contributes to hammer toes. The mucles that keep the little toes straight tend to weaken even without CRPS. Throw in nerve dysfunction and voila curly toes. There are exercises good for this. The pulling a towel toe curls and one I do routinely using a band. with the foot flat on the ground place the band underneath the small toes, pull the band up to lift the toes then pull against the resistance to flatten them back to the floor. Do at least 40 reps since the muscles are tiny and resistance low it takes a lot of reps to get anywhere.

I have had to really stay on top of foot exercises because of a lot of atrophy and muscle dysfunction. A little tedious as a daily routine but worth it. I can't get the CRPS one as beefed up as the other but it is definitely a lot stronger than it used to be.
