Muscle weakness can also be classified as either "proximal" or "distal" based on the location of the muscles that it affects. Proximal muscle weakness affects muscles closest to the body's midline, while distal muscle weakness affects muscles further out on the limbs. Proximal muscle weakness can be seen in Cushing's syndrome [18] and ...
The hallmark of polymyositis is weakness and/or loss of muscle mass in the proximal musculature, as well as flexion of the neck and torso. [1] These symptoms can be associated with marked pain in these areas as well. The hip extensors are often severely affected, leading to particular difficulty in climbing stairs and rising from a seated ...
The "waddling" is due to the weakness of the proximal muscles of the pelvic girdle. [1] The patient uses circumduction to compensate for gluteal weakness. [2] Conditions associated with a myopathic gait include pregnancy, congenital hip dysplasia, muscular dystrophies and spinal muscular atrophy.
“When systemic and chronic inflammation accompanies these underlying diseases, it can affect multiple organ systems, manifesting as fatigue, muscle weakness, digestive disturbances, joint pain ...
Inflammatory myopathy, also known as idiopathic inflammatory myopathy (IIM), is disease featuring muscle weakness, inflammation of muscles , and in some types, muscle pain . The cause of much inflammatory myopathy is unknown ( idiopathic ), and such cases are classified according to their symptoms and signs , electromyography , MRI , and ...
Common early symptoms include frequent tripping and falling and difficulty going up stairs. Foot drop in one or both feet can occur. [14] Part of the cause for this dysfunction is the early involvement of the quadriceps muscles. [1] Weakness of the tibialis anterior muscle is responsible for foot drop. Another common early symptom is trouble ...
The pain is symmetrical, non-radiating and accompanied by sensitivity in the involved bones. Proximal muscles are weak, and there is difficulty in climbing upstairs and getting up from a squatting position. [13] As a result of demineralization, the bones become less rigid. Physical signs include deformities like triradiate pelvis [14] and ...
Corticosteroids often cause muscle weakness to some degree in patients. Symptoms are usually weakness of the proximal muscles, neck flexor, and in extreme cases, respiratory muscle weakness can also occur. [1] Corticosteroids have not only been found to cause some degree of muscle atrophy, but also a local or diffuse cell death. These side ...
