A young woman tries out a bionic hand after losing her fingers and toes:

“Her dad wonders if the financial burden of the bionic hand is worth it. A left hand device won’t be considered until that’s clear. If the bionic hand’s too hard or awkward to use, will it collect dust on her nightstand? ‘She’s good without it. She’s so independent,’ he said once in the doctor’s office. ‘She does it all on her own.’

“Tisa’s progress depends on her determination, Bauer, the orthotist, tells them. And she has already come so far.”
