Cooking is therapy for the hand because many tasks have to be done with both hands.
Below are a few examples of kitchen tasks that force me to use my hemiplegic hand.
The photo shows me holding a Cuisinart container with my hemiplegic hand while my sound hand scrapes out the food that always sticks to the side of the container.
Two more examples - One hand holds a pot still while the other hand stirs the food. One hand opens the refrigerator door and the other hand takes food off a shelf.
A stroke taught me a palmar grasp is useful. In the photo the ends of my fingers are
not touching the object or each other. Why wait until tip pinch emerges when a palmar grasp lets
able-bodied adults to do ADLs that have to be done thousands
of times?
I am not the only one who thinks cooking is therapy for the hand. OTs at Samuel Merritt University had stroke survivors prepare lunch and clean up (1). The group that was helped to use both hands during cooking used their hemiplegic hand more often at home than the group who received constraint-induced therapy. Transferring skills to a new setting is more likely to happen when the practice task closely resembles the target task. homeafterstroke.blogspot.com
