The DASH score is used to assess function of which region?

• A. Upper extremity
• B. Lower extremity
• C. Spine
• D. Head and neck

Answer: (A)

Disabilities of the Arm, Shoulder and Hand (DASH) is an upper-extremity focused patient-reported outcome. It asks patients to rate the difficulty they experience with a broad range of tasks that involve the shoulder, arm, forearm, wrist, and hand, capturing how a condition affects daily activities and function of the upper limb. Because the items center on how the arm and hand work together in everyday tasks, it’s specifically used to assess problems in the upper extremity, such as shoulder or elbow injuries, wrist conditions, or hand function.

This differs from measures used for the lower limb, like those that evaluate leg or hip function, or indices designed for the spine or neck. Those areas have their own condition-specific tools. So the best answer is that the DASH assesses the upper extremity, reflecting its focus on the arm, shoulder, and hand.
