Despite the bulk of the muscle body being visible from the anterior aspect of the forearm, the brachioradialis is a posterior compartment muscle and consequently is innervated by the radial nerve. [5] Of the muscles that receive innervation from the radial nerve, it is one of only four that receive input directly from the radial nerve.
Localized pain on the anterior shoulder suggests subacromial impingement, whereas posterior shoulder pain suggests internal impingement. [45] For the diagnosis of full-thickness rotator cuff tear, the best combination appears to include once more the painful arc and weakness in external rotation, and in addition, the drop arm sign .

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 ...
Some may argue that the tension on muscle is most significant during the mid-range, practice bicep curl with a half range of motion to let muscle generate the most force. [ 4 ] The research found that the preacher curl targets the long head of the biceps significantly only when the arm was almost fully extended, and the range of motion was short.
Immediately after the injury, they may notice some of the signs and symptoms listed in the section above, including pain, ecchymosis, and swelling. [3] [1] Patient with suspected rupture should also be asked about risk factors including corticosteroid use, athletic history, and pre-existing shoulder impingement syndromes or rotator cuff tears.

Signs and symptoms of a dislocation or rotator cuff tear such as: Significant pain, which can sometimes be felt past the shoulder, along the arm. Inability to move the arm from its current position, particularly in positions with the arm reaching away from the body and with the top of the arm twisted toward the back. Numbness of the arm ...
A separated shoulder, also known as acromioclavicular joint injury, is a common injury to the acromioclavicular joint. [2] The AC joint is located at the outer end of the clavicle where it attaches to the acromion of the scapula. [2] Symptoms include non-radiating pain which may make it difficult to move the shoulder.
The recovery depends upon many factors, including where the tear was located, how severe it was, and how good the surgical repair was. [ citation needed ] It is believed that it takes at least four to six weeks for the labrum to re-attach itself to the scapula bone (shoulder blade), and probably another four to six weeks to get strong.
