In pathology, a contracture is a shortening of muscles, tendons, skin, and nearby soft tissues that causes the joints to shorten and become very stiff, preventing normal movement. [ 1 ] [ 2 ] A contracture is usually permanent, but less commonly can be temporary (such as in McArdle disease ), [ 3 ] or resolve over time but reoccur later in life ...
Fibrous tissue, also known as scar tissue, is dense, inelastic tissue that can form after the body heals from an injury. Fibrous bands are fibrous tissue with a long, thin shape like a rope or a band. It's often not clear how internal scarring would materialize.
The condition is sometimes "task-specific", meaning that it is generally apparent during only certain activities. Focal hand dystonia is neurological in origin and is not due to normal fatigue. The loss of precise muscle control and continuous unintentional movement results in painful cramping and abnormal positioning that makes continued use ...
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. [1] In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events ...
A finger contracture caused by Dupuytren's contracture. Muscle contractures can occur for many reasons, such as paralysis , muscular atrophy , and forms of muscular dystrophy . Fundamentally, the muscle and its tendons shorten, resulting in reduced flexibility.
Hypertonia is caused by upper motor neuron lesions which may result from injury, disease, or conditions that involve damage to the central nervous system. The lack of or decrease in upper motor neuron function leads to loss of inhibition with resultant hyperactivity of lower motor neurons .
[4] [16] As a result of frequent tissue injury, there can be an early onset of advanced osteoarthritis, [45] chronic degenerative joint disease, [45] swan-neck deformity of the fingers, [46] and Boutonniere deformity of the fingers. Tendon and ligament laxity offer minuscule protection from tearing in muscles and tendons, but these problems ...
In medicine, myopathy is a disease of the muscle [1] in which the muscle fibers do not function properly. Myopathy means muscle disease (Greek : myo- muscle + patheia -pathy : suffering). This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the ...
