Sample QuestionAngie Western, 35, was referred to you by her doctor for the treatment of carpal tunnel syndrome. Her symptoms appeared about 1 month ago and worsened last week. She cannot type for more than 10 minutes before the pain becomes overwhelming. She has difficulty using utensils and reports that she often drops things. Your assessment confirms carpal tunnel syndrome. During the testing and treatment, you notice that AF and PR ROM elicit moderate bilateral numbness and tingling. As self-care, you prescribe:
