Special tests are often performed to assist in diagnosing musculoskeletal disorders. There are various special tests, each specific for a certain diagnosis. Disorders of muscles, joints, tendons, and ligaments can all be confirmed with a positive finding if the correct special test is performed. This step-by-step program includes three different upper extremity special tests to determine what may be causing your condition. Check in with your healthcare provider, and visit your physical therapist to learn about your particular condition and to maintain optimal mobility and wellness.
Your PT will perform the test as follows:
Stabilize your arm against your bodyFlex your elbow to a 90-degree anglePalpate the bicipital tendonHave you supinate (turn your forearm so that your palm is facing up) and externally rotate the arm against resistanceThis test is positive if there you feel pain in the bicipital groove, or the tester feels the tendon slip out of the groove.
If Yergason’s test is positive, your therapist can work with you to decrease your pain and improve the way your rotator cuff muscles work to support your shoulder. This typically takes pressure off your biceps tendon and can help treat your condition.
Your PT will perform the test as follows:
Abduct your arm to 90 degrees and angle the arm forward 30 degrees at the shoulder joint. Have you internally rotate at the shoulder as if pouring a can on the floorResist you in abduction from this position and assess for weakness or painThe test is positive if there is significant pain or weakness on resistance.
If you have a positive empty can test, your PT may work with your to attempt to strengthen other supporting muscles to improve the function of your shoulder.
Your PT will perform the test as follows:
Monitor your radial pulse at the wrist while they abduct, extend, and externally rotate the upper extremity at the shoulder joint (keeping the elbow straight)Have you take a deep breath, rotate, and extend their head toward the side being testedThe test is positive if there is a marked decrease or absence of the radial pulse.
If you have a positive Adson’s test, you should see your healthcare provider right away to determine the cause of the compression of your artery.
If you have any upper extremity difficulty, you should see your healthcare provider, and then get working with your physical therapist to return to optimal function right away.
