Which neurological evaluation would best assess limb coordination?

The finger-to-nose test is an effective assessment for limb coordination because it specifically evaluates the ability to perform smooth, controlled movements with the upper extremities. During the test, the individual is asked to alternately touch their nose and the examiner's finger, which requires precision and timing. An inability to accurately reach the target can indicate issues with coordination, which may be associated with various neurological conditions affecting the cerebellum or motor pathways.

While the heel-to-shin test also assesses coordination, it is primarily focused on the lower limbs. The Romberg test evaluates balance and proprioception rather than limb coordination. The deep tendon reflex test examines the integrity of the reflex arcs and does not provide information about coordinated voluntary movement. Each of these options assesses different aspects of neurological function, making the finger-to-nose test particularly suitable for evaluating limb coordination.
