Write answer in between .Q:A 47-year-old woman presents to her primary care provider because of numbness and tingling on the palmar aspects of both hands. She denies any symptoms at the base of her thumbs. The symptoms are worse on the right dominant hand and are increased with activities such as driving or brushing her hair. She frequently wakes up with pain and has to shake her hand for pain relief. She has had rheumatoid arthritis for 9 years, for which she takes methotrexate. Her blood pressure is 12476 mm Hg, the heart rate is 75min, and the respiratory rate is 15min. Lightly tapping over the middle of the anterior aspect of the right wrist leads to a tingling sensation in the palm. In this patient, electromyography EMG will most likely show which of the following results?? A: Denervation in C7 innervated paraspinal, arms, and shoulder muscles, B: Widespread symmetrical neuropathic changes without focal abnormalities, C: Widespread denervation in proximal muscles with normal sensory nerves, D: Focal slowing of conduction velocity in the median nerve in the carpal tunnel, E: Neuropathic changes in the palmar branch of the median nerve,  <response>: This is a patient with symptoms of numbness and tingling in the palms of the hands, worse on the right dominant hand. She has a history of rheumatoid arthritis. The symptoms are worsened with activities that involve repetitive wrist motion. Tapping over the wrist reproduces the tingling in the palm. This clinical presentation is most consistent with carpal tunnel syndrome, which is entrapment of the median nerve as it passes through the carpal tunnel in the wrist. The choices describe various EMG findings. Choice A describes findings consistent with a C7 radiculopathy, which would not explain her symptoms. Choice B describes nonspecific widespread neuropathic changes. Choice C describes widespread proximal muscle denervation, also not consistent with her focal hand symptoms. Choices D and E describe abnormalities specific to the median nerve, with choice D being more specific for focal slowing at the carpal tunnel.D: Focal slowing of conduction velocity in the median nerve in the carpal tunnel
