a small geared motor could be hooked up with a cam to move 'back and forth'. If you built an exoskeleton out of aluminum or wood that fit outside the fingers (attached to a light glove), the motor could extend and retract the fingers.

Where does she need to bend her fingers? At the knuckle closest the fingernails, or at the knuckles closest to the palm? (or both?) Does she do any of the work to move her fingers, or is it just a device to move her fingers and rebuild nerves/tissue? How fast do you move her fingers? 'exoskeleton' needs some good building skills. I'm thinking aluminum u-channels that the fingers fit in, with hinges at each knuckle so the fingers can bend. Hinges need to be in the centre of the axis of the knuckle so it bends the same 'way' as the finger does.

this type of motor, with a cam/crank converts rotation into back-and-forth motion. The exoskeleton is a hand-rehab exoskeleton, and is far more complex than you are thinking...but it shows what I mean.

it's a medical tool I just googled 'hand rehab exoskeleton'. I honestly don't know where you'd buy one, it looks like a custom medical device. Ask your doctor?
