: Covers consciousness, orientation, language, and memory—often considered the most vital first step. assessing tone (spasticity vs. rigidity)
: Pinpoint exactly where in the central or peripheral nervous system a problem exists.
: Includes grading muscle strength (MRC 0–5 scale), assessing tone (spasticity vs. rigidity), and observing involuntary movements.
: Detailed testing of modalities like proprioception and vibration, alongside deep tendon and pathological reflexes (e.g., Babinski sign) to differentiate upper vs. lower motor neuron involvement.
