Which tests are used to assess UE coordination?

• A. 9 Hole Peg Test and Moberg Pickup Test
• B. Box and Blocks Test
• C. Purdue Pegboard
• D. Grip Strength Test

Answer: (A)

Coordinated upper-extremity function is shown by smooth, precise, and fast finger and hand movements that integrate sensation with motor control. The 9 Hole Peg Test directly measures finger dexterity and hand-eye coordination by requiring the rapid placement and removal of pegs from nine holes, so it captures how well the fingers and hand work together in a timed task. The Moberg Pickup Test adds a sensorimotor component by having small objects picked up and moved, providing information on fine motor control, tactile feedback, proprioception, and coordinated hand movements. Together, these tests target the coordination aspect of hand function more specifically than others. The Box and Blocks Test emphasizes gross manual dexterity and bilateral hand movement speed, not the fine, coordinated finger tasks. The Purdue Pegboard assesses fingertip dexterity and bimanual coordination in assembly tasks, which is broader but not as focused on the speed and sensory-motor coordination captured by the first two. Grip Strength measures force production, not coordination.
