The mechanism of injury for a distal tendon rupture is forced contraction under eccentric load. [1] [9] A few examples of forced contraction under eccentric load include mixed-grip deadlifts (one forearm pronated and the other supinated, putting the biceps under greater load), preacher curls, and the "kingsmove" technique in armwrestling.
Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. [1] It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. [3] There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple ...
With delayed onset muscle soreness (DOMS) caused by eccentric exercise (muscle lengthening), it was observed that light concentric exercise (muscle shortening) during DOMS can cause initially more pain but was followed by a temporary alleviation of soreness with no adverse effects on muscle function or recovery being observed.
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 ...
“For example, the lowering down phase of a bicep curl could be considered eccentric movement,” adds Landon Uetz, P.T., D.P.T., and pickleball instructor on TeachMe. “The bicep is still ...
It identifies the presence of a pathology involving the biceps tendon or glenoid labrum. The specific positive findings to the test include pain in the bicipital groove indicating biceps tendinitis, [2] [3] subluxation of the long head of the biceps brachii muscle, [3] and presence of a SLAP tear. [4]
Symptoms arising from chronic tears include sporadic worsening of pain, debilitation, and atrophy of the muscles; noticeable pain during rest; crackling sensations when moving the shoulder; and inability to move or lift the arm sufficiently, especially during abduction and flexion motions.
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
