Introduction
The pronator compression test is to differentiate pronator teres syndrome from carpal tunnel syndrome. Dr. Barry Gainor discusses the implications for this test and how pronator teres syndrome is overlooked in individuals with hand paresthesia.[1]
Technique
- Have the patient in a relaxed position
- The examiner applies a firm pressure to the median nerve in the anterior proximal forearm over the pronator teres for 30 seconds
A positive test is the production of the patient's symptoms.
Research
Gainor's article discusses his findings of 10 individuals with hand paresthesia.[1] He states that 50% of the participants in the study either had a prior carpal tunnel decompression surgery or diagnosed with a double crush injury. Additionally, 1 participant did have a positive EMG activity finding prior to participating in the study. Of the 10 participants, 8 had a positive response to the test within 30 seconds. All 10 participants did undergo a median nerve decompression after testing and all participants had either a good or excellent outcome to the decompression surgery.
