Infraspinatus Muscle Pain Test
The test for infraspinatus muscle pain is not directly stated in the provided studies. However, some studies mention tests that can be used to diagnose rotator cuff tears or subacromial impingement, which may be related to infraspinatus muscle pain.
- The Jobe test, external rotation lag sign, and Hawkins-Kennedy test are mentioned in the study 1 as tests that can be used to diagnose posterosuperior rotator cuff tears, which may involve the infraspinatus muscle.
- The Neer test, Hawkins-Kennedy test, painful arc test, empty can test, and external rotation resistance test are mentioned in the study 2 as tests that can be used to diagnose subacromial impingement syndrome, which may also be related to infraspinatus muscle pain.
- The study 3 mentions that experimental subacromial pain can elicit a decline in force and voluntary activation of the infraspinatus muscle, but it does not provide a specific test for diagnosing infraspinatus muscle pain.
Diagnostic Tests for Related Conditions
Some studies provide information on diagnostic tests for related conditions, such as:
- Subacromial impingement syndrome: The study 2 found that the painful arc test, empty can test, and external rotation resistance test had a positive likelihood ratio greater than or equal to 2.0, indicating that they may be useful for confirming the diagnosis of subacromial impingement syndrome.
- Posterosuperior rotator cuff tears: The study 1 found that the Jobe test had the highest pooled sensitivity for diagnosing posterosuperior rotator cuff tears, while the drop arm sign had the best pooled specificity.
- Femoroacetabular impingement: The study 4 found that the IROP test, impingement sign, and FABER test had the most sensitive values for identifying femoroacetabular impingement.
Note that these tests may not be specific to infraspinatus muscle pain, but rather to related conditions that may involve the infraspinatus muscle.
