Osteoporosis is a widespread condition characterized by low bone mass or density. It is primarily a metabolic disorder related to age and general health with a variety of risk factors and causes. The most common and well-known consequence of osteoporosis is weakened bones that can break from small forces that would usually be harmless.
Frozen shoulder, also known as adhesive capsulitis, is a condition affecting the joint capsule of the shoulder. It is characterized by inflammation of the capsule, leading to pain and stiffness with shoulder movements.
Shoulder instability is a term used to describe a weakness in the structures of the shoulder that keep the joint stable, often leading to frequent dislocations. As one of the most flexible joints in the body, the shoulder maintains stability through a balance of support between the dynamic structures (muscles and tendons) and static structures (ligaments and joint shape).
Chronic ankle instability, as the name implies, is a chronic condition of instability affecting the ankle and it’s surrounding structures. It usually develops after a severe ankle sprain. However, some people are born with less stable ankles; these individuals are generally extra flexible throughout their bodies. Approximately 20% of ankle sprains lead to chronic ankle instability due to the resulting changes in ligament support, strength, postural control, muscle reaction time and sensation.
