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 ...
Distal tendon rupture will cause significant weakness with respect to forearm supination and flexion, whereas proximal tendon ruptures do not cause significant weakness as a result of their dual proximal tendinous attachments serving as redundancy. [1] [4] This image shows a biceps brachii tendon rupture on the right arm.
The diagnosis of polyneuropathy begins with a history (anamnesis) and physical examination to ascertain the pattern of the disease process (such as arms, legs, distal, proximal), if they fluctuate, and what deficits and pain are involved. If pain is a factor, determining where and how long it has been present is important; one also needs to ...
Left arm pain can happen after an injury or pinched nerve. But in some cases, it could be an early indicator of a heart problem. Here’s what you need to know.
The sensory changes can be a feeling of numbness or a tingling, pain rarely occurs in the hand. Complaints of pain tend to be more common in the arm, up to and including the elbow area, which is probably the most common site of pain in an ulnar neuropathy. [1] [2]
By definition, all limb girdle muscular dystrophies (LGMD) cause progressive proximal weakness, [3] meaning weakness of the muscles on or close to the torso that worsens over time. Explicitly, LGMD preferentially affects muscles of the hip girdle, thigh, shoulder girdle, and/or upper arm. [8] [6] The muscle weakness is generally symmetric. [11]
The symptoms of chronic exertional compartment syndrome, CECS, may involve pain, tightness, cramps, weakness, and diminished sensation. [20] This pain can occur for months, and in some cases over a period of years, and may be relieved by rest. [21] Moderate weakness in the affected region can also be observed.
The cardinal signs of brachial plexus injury then, are weakness in the arm, diminished reflexes, and corresponding sensory deficits. [11] [citation needed] Erb's palsy. "The position of the limb, under such conditions, is characteristic: the arm hangs by the side and is rotated medially; the forearm is extended and pronated.
