Here are some tips that can help.
A little rearranging can make kitchen work a lot easier. Items that are not used regularly or are purely decorative are best stored elsewhere, such as in another room or in out-of-the-way storage areas. This will allow more space on counters and tables and in easily accessible storage areas for daily use items, such as frequently used pots, pans, utensils, dishes, and seasonings.
Using turntables on counters and tables can make accessing those frequently used items easier.
If disability is expected to be long-term or permanent, kitchen remodeling may be in order. Helpful adaptations may include:
Installing cabinets with roll-out trays and bins for easy access to stored items
Smooth-surface range or cook-top for sliding pans off the heat rather than lifting them
A food prep counter or table with knee room for people who use wheelchairs
Lowered, fairly shallow sinks with knee room beneath to make cleanup easier
Hand operated grabbing tools are very useful for reaching things in awkward places. They are made in a wide assortment of shapes, sizes, and types, so finding a few to meet everyday needs in the kitchen should not be a problem.
If dexterity is an issue, or there is weakness on one side of the body, adaptive kitchen equipment can offer help for physical disabilities – for example, cutting boards with a spike to hold vegetables as they are chopped or hands-free faucets
Planning meals ahead and making a list of necessary ingredients for each one can help reduce back-and-forth travel to gather needed items during meal preparation. If fatigue is an issue, plan meals that can be broken down into a series of steps, enabling breaks between them.
If mobility is an issue, a rolling utility cart makes transporting items needed from the refrigerator, cabinets, or pantry easier. This also makes it possible to transport the items you need in one trip. If a wheelchair is used, a lap tray with a beanbag base can serve the same purpose.
Of course, there are a lot more items and ideas out there for providing help for physical disabilities that can work to make navigating the kitchen safer and easier for your family member or friend. Your local rehabilitation center or your loved one's physical therapist could likely offer some recommendations that are suitable to their individual circumstances, abilities, and limitations.
