Shoulder impingement occurs when tendons or bursae are compressed, often causing pain when reaching overhead or behind you. It's linked to poor posture, weak rotator cuff muscles, and tight chest muscles. Strengthening, posture correction, and stretching usually relieve symptoms.

Total knee replacement can relieve pain and restore function for people with knee osteoarthritis. Innovations, such as robotic-assisted surgery, personalized 3D-printed implants, and enhanced protocols for rehabilitation and pain control, aim to further improve results.

"Bone-on-bone" is a common description for advanced osteoarthritis, when the cartilage in a joint wears away completely. Symptoms, including pain, stiffness, and limited motion, can be managed with physical therapy, weight loss, pain medications, injections, and possibly joint replacement.

Hours spent sitting can leave a person's hips feeling stiff and sore, often because the hip flexor muscles have tightened and shortened. Understanding how these muscles work and practicing simple stretches regularly can relieve discomfort and improve flexibility.

Low back pain is common. It often results from poor posture, bad ergonomics, unusual movement patterns, and age-related spinal changes. Ignoring pain can lead to muscle weakness and instability. Early care, including physical therapy, helps relieve pain and prevent future problems.

A variety of everyday habits can stealthily reduce bone health. These include consuming too little calcium, excessive caffeine or soda, inadequate protein, and large amounts of alcohol, as well as smoking, being sedentary, dieting frequently, or taking certain medications.

For people with knee osteoarthritis, walking pattern (called gait) matters. Pain can lead to habits like shuffling or shortening steps, increasing joint stress. Gait training, along with strengthening, stretching, and balance, can help normalize walking, improve stability, and reduce knee strain.

A 2025 study suggested that women with a history of infertility, miscarriage, or stillbirth or who have borne just one child or no children may be likelier to eventually develop osteoporosis.

A 2025 study found that for people with advanced knee osteoarthritis in which the damage is limited to one side of the joint, partial knee replacement is as effective as total knee replacement for pain relief and improved function and carries a similar need for additional surgeries within 10 years.

A 2025 study found that people ages 50 to 90 who received treatment within one week after a moderate or severe traumatic brain injury had a 41% lower risk of developing Alzheimer's disease over the following three years, suggesting that early treatment may be important.
