Older adults need a strong core to stay active and healthy. While the core comprises many muscles, the four main ones lie within the abdomen: the rectus abdominis in the front; the external and internal obliques on the sides; and the deep, flat transversus abdominis wrapping your midsection. Several core exercises work many of these muscles, but the dead bug exercise can engage all of them and is safe for older adults, as it can be modified for any age or limitations. The dead bug is done by lying on the back and moving the limbs up and down to imitate a dying insect.

Arthritis in the joint at the base of thumb (the carpometacarpal joint) can cause pain, weakness, and instability. It can seriously impair the ability to function. Thumb arthritis is diagnosed with a physical examination and x-rays. It can be managed with occupational therapy, which includes learning optimal hand positions and exercises and wearing a hand splint. Pain relief options include heat, pain medications, and cortisone injections. If these are inadequate or the condition is severe, surgery is an option.
