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 is symmetric, progressive, and proximal (on or close to the torso), usually affecting the hip girdle and shoulder girdle muscles. [1] [3] Hip weakness can manifest as a waddling gate. [1] Shoulder weakness can manifest as winged scapulas. [1] Muscle contractures, especially of the Achilles tendon, and scoliosis can also occur. [1]
True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis. Muscle weakness can also be caused by low levels of potassium and other electrolytes within muscle cells. It can be temporary or ...
A variety of methods may be used to diagnose axillary nerve palsy. The health practitioner may examine the shoulder for muscle atrophy of the deltoid muscle. [2] Furthermore, a patient can also be tested for weakness when asked to raise the arm. [2] The deltoid extension lag sign test is one way to evaluate the severity of the muscle weakness.
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
Muscle weakness usually becomes noticeable on one side of the body before the other, a hallmark of the disease. [14] The right shoulder and arm muscles are more often affected than the left upper extremity muscles, independent of handedness. [23]: 139 [24] [25] [26] Otherwise, neither side of the body has been found to be at more risk.
Medical history (the patient tells the doctor about an injury). For shoulder problems the medical history includes the patient's age, dominant hand, if injury affects normal work/activities as well as details on the actual shoulder problem including acute versus chronic and the presence of shoulder catching, instability, locking, pain, paresthesias (burning sensation), stiffness, swelling, and ...
The shoulder joint is made up of three bones: the shoulder blade (scapula), the collarbone (clavicle) and the upper arm bone (humerus). The acromion is a bony process at the end of the scapula The shoulder is a complex mechanism involving bones, ligaments , joints , muscles , and tendons .
