A 34-year-old woman is diagnosed with carpal tunnel syndrome. Which of the following treatments does NOT improve function in carpal tunnel syndrome?

Choice A reason: Occupational therapy, including activity modification and ergonomic interventions, can improve hand function and reduce symptoms in carpal tunnel syndrome, making it an effective non-surgical treatment. Choice B reason: NSAIDs may help reduce pain and inflammation, although they have limited effect on nerve function. They are used as a supportive treatment but do not directly improve long-term function. Choice C reason: Splinting, particularly at night, helps maintain the wrist in a neutral position, reducing pressure on the median nerve and improving functional symptoms. It is a widely recommended non-invasive intervention. Choice D reason: Joint replacement is not indicated for carpal tunnel syndrome. This procedure addresses joint pathology, not median nerve compression, and does not improve hand function in CTS. It is irrelevant to the treatment of this condition.
