Recently, a patient with anterior shoulder pain who had received a cortisone injection into her biceps tendon reported that it did not alleviate her shoulder pain. I inquired as to how the doctor had determined that her biceps were involved. She said he palpated the area that was tender and did a test - she held her shoulder extended in front of her, with her hand supinated, and resisted his downward pressure. She said doing so was painful. The doctor had performed Speed's test for biceps involvement.
A recent study in the American Journal of Sports Medicine1 (AJSM) suggests that a positive Speed's test for a possible partial tear of the biceps, and even tenderness over the bicipital groove, are not necessarily valid for proving biceps involvement. It is very interesting how tests we take for granted eventually may be disproved. This has occurred with tests for shoulder labral tears.2
I have always regarded a positive functional test as more valid than tenderness over an area. Here is a case in which they both are equivocal. In the recent AJSM study,1 847 patients underwent diagnostic arthroscopy of the shoulder and 40 were found to have partial biceps tears, to which Speed's test and palpation was pretested. The sensitivity and specificity tests were about 50 percent accurate when palpation and Speed's test were used.
The authors state that palpation of the biceps tendon is difficult because it lies deep in the shoulder and is covered by other structures. It is especially difficult in obese or heavily muscled subjects. The lever-arm position of the biceps in the Speed's test stimulates many of the surrounding muscles. Shoulder motion does not produce any electrical activity in the biceps muscle but becomes electrically active with elbow flexion and extension.1 Probably the best way to test the biceps is with the elbow in 90 degree flexion with the arm in supination, held against the trunk.2

In a landmark development, Blue Cross Blue Shield (BCBS) has reached a $2.8 billion settlement to resolve antitrust claims brought by health care providers, including chiropractors. The lawsuit accused BCBS of dividing the nation into exclusive regions and limiting competition, which resulted in lower reimbursements for providers. Although BCBS denies any wrongdoing, the company agreed to the settlement to avoid lengthy litigation – and you can get a piece of the pie.
The World Federation of Chiropractic (WFC) Board of Directors passed a “Policy on Non-Interference and Respect for National Authority” at its Q3 2024 meeting. Upon reading this, some might ask if the WFC policy is targeting the activities of the American Chiropractic Association (ACA) in providing international membership to Japanese individuals who do not hold a chiropractic degree from an accredited institution.
