Performing hand exercises using therapy putty can help a person improve grip and pinch strength.

Walking and running share similar movements, but how the foot is supported differs, which is why most walking and running shoes are designed differently. When walking, the heels hit the ground first before the foot rolls forward to begin the next step. Because of this rolling motion, walking shoes are designed to have soft, flexible soles, which help a person push off with each step, and an angled heel to absorb most of the shock and reduce pressure on the ankles. In comparison, runner’s feet strike anywhere from the heel to the midfoot or forefoot. Therefore, running shoes are designed to have thicker soles that act as shock absorbers.

Most people will experience shoulder pain at some point in their lives. The most common causes of shoulder pain are bursitis, rotator cuff problems, frozen shoulder, and osteoarthritis. They can occur for various reasons, such as overuse, injury, and age-related wear and tear. A doctor may be able to make a likely diagnosis based on a person’s symptoms, a shoulder exam, and sometimes MRI. Treatment often includes a combination of rest, over-the-counter medication, corticosteroid injections, and physical therapy. In some cases, surgery is needed to repair damage.
