Which bilateral upper-extremity coordination task is described as symmetrical?

RAM Alternating knee to shoulder Clapping Finger to nose

Correct Answer:

Clapping

Explanation:

Bilateral upper-extremity coordination that is symmetrical means both arms move together in the same pattern, at the same time, with similar speed and range. Clapping exemplifies this because both hands move in harmony, striking together with matched amplitude and rhythm. Rapid alternating movements test coordination by requiring quick, alternating actions, which emphasizes timing and smoothness of switching movements rather than simultaneous symmetry. Finger-to-nose is typically performed with one arm at a time and focuses on accuracy and proprioception rather than synchronized dual-arm action. Alternating knee to shoulder isn’t an upper-extremity task and doesn’t illustrate symmetric bimanual coordination. So clapping best shows symmetrical bilateral coordination.
