Muscle atrophy is the loss of skeletal muscle mass. It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Muscle atrophy leads to muscle weakness and causes disability.
Parry–Romberg syndrome (PRS) is a rare disease presenting in early childhood [1] characterized by progressive shrinkage and degeneration of the tissues beneath the skin, usually on only one side of the face (hemifacial atrophy) but occasionally extending to other parts of the body. [2]
Facioscapulohumeral muscular dystrophy (FSHD) is a type of muscular dystrophy, a group of heritable diseases that cause degeneration of muscle and progressive weakness. Per the name, FSHD tends to sequentially weaken the muscles of the face, those that position the scapula, and those overlying the humerus bone of the upper arm.
That muscle soreness, specifically the delayed-onset muscle soreness (DOMS) you feel a day or two after a hard workout, is the result of small tears in your tissues, according to a study published ...
There are many proposed causes of sarcopenia and it is likely the result of multiple interacting factors. Understanding of the causes of sarcopenia is incomplete, however, changes in hormones, immobility, age-related muscle changes, nutrition, and neurodegenerative changes have all been recognized as potential causative factors.
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
Muscle injury (such as a large burn or surgery) can cause muscle contractures as internal scar tissue (adhesions and fibrosis) develops. Repetitive muscle injuries (e.g. sports injuries, major muscle strains) and micro-injuries (e.g. overuse injuries, minor muscle strains) can also cause this. Adhesions and fibrosis are made of dense fibrous ...
Activation of trigger points may be caused by a number of factors, including acute or chronic muscle overload, activation by other trigger points (key/satellite, primary/secondary), disease, psychological distress (via systemic inflammation), homeostatic imbalances, direct trauma to the region, collision trauma (such as a car crash which stresses many muscles and causes instant trigger points ...
