My mother, at 94, broke her wrist and was in rehab. The OT worked on things like putting on shoes (laces were replaced with elastic ones so that they could be slipped on), helping her use a fork to eat, brush teeth, get in and out of a chair… In other words, teaching the chores of daily living. I think that you don’t need the kind of muscle that PT’s use. There are lots of devices and tricks. When my mother got home, the OT came and taught her hand exercises with squishy balls, weight-bearing with soup cans, etc. Go for it. People are living longer and needing more ancillary help.
