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 ...
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 ...
Pain along the front and side of the shoulder is the most common symptom and may cause weakness and stiffness. [3] If the pain resolves and weakness persists other causes should be evaluated such as a tear of the rotator cuff or a neurological problem arising from the neck or entrapment of the suprascapular nerve.
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.
Those that do have symptoms tend to have intermittent shoulder pain, particularly during forward shoulder flexion (i.e. lifting the arm in front of the body). [1] In the "resorptive phase" when the calcium deposit is breaking down, many experience severe acute pain that worsens at night. [ 1 ]
The neurogenic type is the most common and presents with pain, weakness, paraesthesia, and occasionally loss of muscle at the base of the thumb. [1] [2] The venous type results in swelling, pain, and possibly a bluish coloration of the arm. [2] The arterial type results in pain, coldness, and pallor of the arm. [2]
This syndrome can begin with severe shoulder or arm pain followed by weakness and numbness. [5] Those with Parsonage–Turner experience acute, sudden-onset pain radiating from the shoulder to the upper arm. Affected muscles become weak and atrophied, and in advanced cases, paralyzed. Occasionally, there will be no pain and just paralysis, and ...
The pain may occur with shoulder movement above the horizontal position, shoulder flexion and abduction. [12] [13] Pain is often described as weakness. Actual muscle weakness does not correlate with symptoms of weakness. Symptom severity does not correlate with rotator cuff defect size and associated muscle quality. [14]
