Plantar Reflex & the Babinski Sign EXPLAINED

The video tutorial explains the plantar reflex, a key superficial reflex used to assess neurological damage, particularly upper motor neuron signs. It details the procedure for performing the test, including patient positioning and the use of a reflex hammer. The video also covers how to interpret results in both adults and infants, noting that normal and abnormal responses differ between these groups. Additionally, it discusses the psychometric properties of the test, highlighting its sensitivity and specificity in detecting upper motor neuron lesions.
