Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion. It is particularly associated with tendonitis of the supraspinatus muscle. [1] This can result in pain, weakness, and loss of movement at the ...
Weakness comes on slowly (over months to years) in an asymmetric manner and progresses steadily, leading to severe weakness and wasting of arm and leg muscles. IBM is more common in men than women. [10] Patients may become unable to perform activities of daily living and most require assistive devices within 5 to 10 years of symptom onset.
The doctor assesses for muscle weakness or rashes. Another possible test is electromyography. This test involves the insertion of small needles into the patient's muscles. [4] This allows a physician to look at the muscles' responses to various electrical nerve stimuli and evaluate which muscles potentially have myositis. [4]
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 ...
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 ...
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 brain). This muscular defect typically results in myalgia (muscle pain), muscle weakness (reduced muscle force), or premature muscle fatigue (initially normal, but declining muscle force).
Muscle cramps could also potentially stem from a nerve problem (such as nerve compression), exercising in the heat, a lack of stretching, muscle fatigue, body stress, medication side effects or ...
The serum creatine phosphokinase (CPK) can be mildly elevated. [11] While the CPK is often a good marker for damage to muscle tissue, it is not a helpful marker in CIP/CIM, because CIP/CIM is a gradual process and does not usually involve significant muscle cell death . Also, even if necrosis is present, it may be brief and is therefore easily ...
