A 45-year-old female patient presents to your clinic with a 3-month history of numbness, tingling, and pain in her right hand, particularly affecting the thumb, index, and middle fingers. She reports that her symptoms are worse at night and often wake her up. The patient works as a data entry clerk and spends most of her day typing on a keyboard. On physical examination, you note no visible swelling, redness, or deformity of the hand. Based on her history and occupation, you suspect a specific nerve entrapment syndrome in her right hand. Given the patient’s presentation, which physical exam test would best be performed to assess the patient’s issue?
