How to test the biceps tendon reflex

The biceps tendon reflex is a method to detect whether the body is normal or not. It is generally performed on patients suspected of having nerve abnormalities or damage. This has positive significance for timely judgment of whether the nerve reaction is normal, so it must be taken seriously. It is particularly necessary to go to a regular hospital for examination. So how to detect the biceps tendon reflex? Let us learn about it below.

Precautions

Unsuitable groups: patients with arm disabilities or injuries.

Taboos before examination: Relax your arms before examination.

Requirements for examination: The examination can be conducted in supine or sitting position.

Inspection process

(1) Supine examination method: The patient lies on his back with his forearms semi-flexed, muscles relaxed, and hands placed on the abdomen. The examiner presses the biceps tendon slightly above the elbow joint with the left thumb, and then taps the thumb with the percussion hammer held in the right hand. Normally, this causes the forearm to flex.

(2) Examination in the sitting position: The patient sits, and the examiner supports the patient's elbow with his left hand and his forearm with his left forearm. Then, he presses his left thumb on the patient's biceps tendon and taps the thumb with a percussion hammer. Under normal circumstances, the reaction is the same as above.

During the examination, if the above reactions are hyperactive, weakened or absent, it is an abnormal biceps reflex.

Through the above introduction, we know how to detect the biceps tendon reflex. When conducting the test, we must first go to a regular hospital, which can effectively ensure the accuracy of the test. In addition, after discovering the problem, active and systematic treatment should be carried out, especially patients should also pay attention to the conditioning of daily life.
