What is Phalen's Test?
Phalen's Test is a diagnostic maneuver used to identify
carpal tunnel syndrome (CTS). This condition occurs when the
median nerve is compressed as it travels through the carpal tunnel in the wrist. The test is named after Dr. George S. Phalen, an American orthopedist who first described it.
How is Phalen's Test Performed?
To perform Phalen's Test, the patient is asked to flex their wrists and press the backs of their hands together, forming a right angle. This position is held for about 60 seconds. During this time, the nurse observes for symptoms such as
tingling,
numbness, or pain in the fingers, particularly the thumb, index, middle, and ring fingers, which are innervated by the median nerve.
Frequent
hand numbness or tingling
Wrist pain, especially at night
Weakness in the hand
Difficulty performing tasks that require fine motor skills
What are the Contraindications?
While Phalen's Test is generally safe, it should be avoided in patients with severe wrist trauma or conditions that limit wrist mobility, such as a
fracture or severe
arthritis. In such cases, alternative diagnostic methods should be considered.
Explaining the procedure to the patient
Ensuring patient comfort and proper positioning
Observing and documenting the patient's symptoms
Communicating findings to the healthcare provider
Moreover, nurses can educate patients on
ergonomic practices and wrist exercises to alleviate symptoms of carpal tunnel syndrome.
Conclusion
Phalen's Test is a simple yet effective diagnostic tool for identifying carpal tunnel syndrome. While it has its limitations, it remains a valuable component of a comprehensive clinical assessment. Nurses play a vital role in the execution and interpretation of this test, contributing significantly to patient care and management.
