pediatric_nih_stroke_scale: Pediatric NIH Stroke Scale (PedNIHSS)

Description

Calculates the Pediatric NIH Stroke Scale (PedNIHSS) score. This is a validated adaptation of the standard NIHSS for use in children, using age-appropriate stimuli and instructions to assess neurological deficits in acute stroke. The scoring values (0 to 4) for each domain remain consistent with the adult scale.

Usage

pediatric_nih_stroke_scale(loc_responsiveness, loc_questions, loc_commands, gaze,
                           visual_fields, facial_palsy, motor_arm_left,
                           motor_arm_right, motor_leg_left, motor_leg_right,
                           limb_ataxia, sensory, best_language, dysarthria,
                           extinction_inattention)
