A patient presents with symptoms of carpal tunnel syndrome. Which of the following may worsen the condition?

• A. Frequent wrist flexion
• B. Heavy lifting
• C. Prolonged standing
• D. Increased hydration

Answer: (A)

Frequent wrist flexion is associated with the exacerbation of symptoms in carpal tunnel syndrome due to the anatomical and physiological changes that occur in the carpal tunnel. When the wrist is flexed, the space within the carpal tunnel is reduced, which can increase pressure on the median nerve that runs through this tunnel. This increased pressure can lead to more pronounced symptoms such as numbness, tingling, and pain in the hand and fingers.

In contrast, while heavy lifting might contribute to symptoms due to increased strain on the wrist and forearm muscles, it is not as directly linked to the specific anatomical concerns of the carpal tunnel as wrist flexion is. Prolonged standing is unrelated to the mechanics of the wrist, and increased hydration does not have a direct negative impact on carpal tunnel syndrome symptoms. Therefore, frequent wrist flexion is the most critical factor to consider in worsening the condition.
