Try to use your own range of motion and strength to perform tasks, but when you’re tired, stiff or in pain, helpful devices can make tasks easier, more efficient and less stressful for your muscles and joints. Many assistive devices can help you use your joints wisely and prevent further deformity. They also can help by providing additional strength, extending your reach, preventing strain, and keeping your body in the best position for certain tasks. Ask your doctor or physical or occupational therapist about helpful devices.
