Biceps Squeeze Test:

• This Biceps Squeeze Test is applied to the clinic to check the rupture of the biceps tendon.
• This clinical or orthopedic test is applied by to doctor or therapist to check the third-degree strain [3′].
• This test is applied to examine part of the assessment.

What is bBiceps tendon rupture?

• Biceps tendon rupture is due to the excessive eccentric force when the arm is brought into extension from the flexion position.
• These excessive activities include labor-intensive jobs, wrestling, weightlifting.
• Risk factors of the rupture of the biceps tendon include obesity, smoking, age, overuse & use of corticosteroids drugs,
• The incidence of rupture of the biceps tendon is around 2.55 per 100,000 patients in 1 year.
• Most of the patients for rupture of the biceps tendon are males around more than 95%.
• Age of patient for rupture of the biceps tendon is middle age between 35 years to 54 years.
• Mostly this Rupture occurs in the dominant limb.

What is the Purpose of the Biceps Squeeze Test?

• The Biceps Squeeze Test is used to check the rupture of the distal biceps tendon.
• This Biceps Squeeze Test is also used to check the 3′ degree strain of the biceps tendon.

What is the Technique of performance of the Biceps Squeeze Test?

• The patient position for the test is in a sitting position with the forearm is supported comfortably on the patient’s lap.
• Then Elbow is flexed approximately up to 60-80 degrees.
• At this situation of flexion, stress is on the brachialis muscle minimizes & with the help of isolating the biceps muscle from the forearm in supination.
• The forearm is slightly pronated.
• The examiner stands on the side of the limb which is examined by the side of the patient.
• After that The examiner is squeezed the biceps brachii muscle firmly with both hands, the patient places one hand on the myotendinous junction & the other hand of the examiner is around the muscle belly.
• So that when the biceps brachii muscle is squeezed, it is a deformation of the proximal muscle which creates tension in the distal tendon of the biceps resulting in the forearm being in supination position.
• This would not occur if the distal tendon is avulsed from its insertion on the radius.

What is result of the Biceps Squeeze Test?

• A positive Biceps Squeeze Test indicates the absence of the supination in the forearm during the test.
• It shows the rupture of the distal biceps tendon.

Hook test:

• This is another test that is used to check the rupture of the biceps tendon.

• The patients abducted the shoulder to 90′ with the elbow flexed to 90′ & the arm supinated so that the thumb faces up.
• The patient is then asked to actively supination the forearm against the resistance of the examiner.
• With the index finger of the other hand, the examiner attempts to hook underneath the biceps tendon, hooking from lateral to medial at the same time.
• If no cord-like structure can be hooked, the test is positive for a rupture of the distal biceps.
