Shoulder pain is a common complaint among athletes and active individuals. It can be caused by a variety of factors, including overuse, injury, or underlying medical conditions. One diagnostic tool that can help identify the source of shoulder pain is the biceps load test. In this article, we’ll explore what the biceps load test is, how it’s performed, and what the results can indicate. Whether you’re a healthcare professional, athlete, or someone dealing with shoulder pain, this article will provide you with valuable insights into this important diagnostic test.
What is the biceps load test?
The biceps load test is a physical examination technique used to assess shoulder pain and potential injuries to the biceps tendon. During the test, the patient’s arm is positioned in a specific way to place tension on the biceps tendon, and the examiner then applies resistance while the patient performs a specific movement. The goal is to determine whether the tendon is intact and to identify any potential tears or other injuries. The biceps load test is a simple, non-invasive diagnostic tool that can provide valuable information about the cause of shoulder pain and guide appropriate treatment.
The biceps load test is typically performed by a healthcare professional, such as a physical therapist, sports medicine physician, or orthopedic surgeon. The test can be done in a clinical setting, and it usually takes only a few minutes to complete.
During the test, the patient’s arm is positioned in 90 degrees of shoulder abduction with the elbow flexed to 90 degrees, and the examiner then applies a downward force to the patient’s forearm while the patient resists. The goal is to stress the biceps tendon while keeping the shoulder joint stable. The examiner will assess the patient’s ability to maintain the position and the presence of any pain or weakness.
How is the biceps load test performed?
To perform the biceps load test, the patient is positioned in a seated or supine position, and the examiner stands beside them. The arm being tested is positioned in 90 degrees of shoulder abduction and elbow flexion. The examiner will then apply a downward force to the forearm while the patient resists by attempting to straighten the elbow against the force applied by the examiner.
During the test, the examiner will assess the patient’s ability to maintain the position and the presence of any pain or weakness. They will also check for any “pop” or “click” sounds, which may indicate a biceps tendon tear.
The biceps load test can be modified to assess different aspects of biceps tendon function, depending on the patient’s symptoms and suspected injury. For example, the Speed’s test is a variation of the biceps load test that is used to assess for biceps tendonitis or tendonopathy. During this test, the arm is positioned in a similar manner, but the patient is asked to resist an upward force applied to the forearm while the elbow is extended.
Overall, the biceps load test is a simple and non-invasive test that can be performed in a clinical setting by a healthcare professional. It provides valuable information about the function and potential injury of the biceps tendon, which can guide appropriate treatment.

What do the results of the biceps load test indicate?
What do the results of the biceps load test can indicate whether there is a tear or other injury to the biceps tendon, as well as the location and severity of the injury. If the biceps tendon is intact, the test will be negative, and the patient will be able to resist the downward force applied by the examiner without pain or weakness.
If there is a biceps tendon tear or injury, the test may be positive, indicating weakness or pain during the test. The location and severity of the injury can be determined by the type of weakness or pain experienced. For example, if the patient experiences pain near the shoulder joint, it may indicate a tear at the proximal end of the tendon, whereas weakness or pain near the elbow may indicate a tear at the distal end of the tendon.
In addition to assessing for biceps tendon injury, the biceps load test can also help differentiate between injuries to the biceps tendon and injuries to other structures in the shoulder, such as the rotator cuff. This information is critical for guiding appropriate treatment and rehabilitation.
Overall, the results of the biceps load test can provide valuable information about the source and severity of shoulder pain, and help healthcare professionals develop an appropriate treatment plan.

What Conditions can the biceps load test help diagnose?
The biceps load test can help diagnose several conditions that cause shoulder pain and weakness, including:
- Biceps tendonitis: This is an overuse injury that causes inflammation of the biceps tendon. The biceps load test can be used to assess for biceps tendonitis, as the test can reproduce the pain associated with this condition.
- Biceps tendon tear: A tear in the biceps tendon can cause pain and weakness in the shoulder and arm. The biceps load test can be used to assess for a biceps tendon tear, as the test will be positive if there is weakness or pain during the test.
- SLAP tear: A SLAP (superior labrum anterior and posterior) tear is a tear in the cartilage that surrounds the shoulder socket. The biceps load test can help diagnose a SLAP tear by reproducing the pain associated with this condition.
- Rotator cuff tear: The rotator cuff is a group of muscles and tendons that surround the shoulder joint. A tear in the rotator cuff can cause pain and weakness in the shoulder. The biceps load test can help differentiate between a rotator cuff tear and a biceps tendon tear, as the test is specific to the biceps tendon.
- Shoulder impingement: Shoulder impingement occurs when the tendons and bursae in the shoulder become compressed or pinched. The biceps load test can help diagnose shoulder impingement, as it can reproduce the pain associated with this condition.
Overall, the biceps load test is a valuable diagnostic tool that can help healthcare professionals diagnose a variety of shoulder conditions that cause pain and weakness. It can guide appropriate treatment and rehabilitation, leading to improved outcomes for patients.

How does the biceps load test compare to other diagnostic tests for shoulder pain?
The biceps load test is a physical examination technique that can help diagnose certain shoulder conditions that cause pain and weakness, including biceps tendonitis, biceps tendon tears, and SLAP tears. While the biceps load test is a useful diagnostic tool, it is often used in combination with other tests to get a complete picture of the patient’s shoulder condition.
Other diagnostic tests that may be used in combination with the biceps load test include:
- MRI (Magnetic Resonance Imaging): An MRI can provide detailed images of the soft tissues in the shoulder, including the biceps tendon and rotator cuff. MRI is a non-invasive test that can help diagnose a variety of shoulder conditions.
- Ultrasound: An ultrasound is another non-invasive imaging test that can help diagnose shoulder conditions. It can provide real-time images of the biceps tendon and other soft tissues in the shoulder.
- X-ray: X-rays can be used to diagnose bone injuries and conditions that affect the bony structures of the shoulder, such as arthritis.
- Arthroscopy: Arthroscopy is a minimally invasive surgical procedure that can be used to diagnose and treat certain shoulder conditions, including biceps tendon tears and SLAP tears.
Overall, the biceps load test is a useful diagnostic tool, but it is often used in combination with other tests to get a complete picture of the patient’s shoulder condition. The specific diagnostic tests used will depend on the patient’s symptoms and suspected diagnosis.

Are there any risks or complications associated with the biceps load test?
The biceps load test is a relatively safe and non-invasive diagnostic test, and there are typically no significant risks or complications associated with it. However, as with any physical examination technique, there is a small risk of injury or aggravation of an existing injury or condition.
In some cases, the biceps load test can cause pain or discomfort, particularly if the patient already has an injury or condition affecting the biceps tendon. The examiner will typically proceed with caution and adjust the test as necessary to avoid causing unnecessary pain or discomfort.
In rare cases, the biceps load test can cause further injury to the biceps tendon, particularly if the tendon is already torn or partially torn. If the examiner suspects that the patient may have a biceps tendon tear, they may order additional imaging tests, such as an MRI, to confirm the diagnosis before proceeding with the test.
Overall, the biceps load test is a safe and effective diagnostic tool when performed by a trained healthcare professional. Any potential risks or complications associated with the test are generally minor and can be managed by the examiner.
