Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Scissor gait is a spastic gait in which the legs cross over each other (adduction at the hips) with each step, due to increased tone in the hip adductors.
Step 2: It results from an upper motor neuron lesion that produces spasticity. The classic cause is spastic (especially diplegic) cerebral palsy.
Step 3: Polio causes a flaccid (lower motor neuron) paralysis, not spasticity, so it produces a different gait. Hyponatremia and uncomplicated hyperbilirubinemia do not produce a chronic spastic scissoring gait.
Step 4: Therefore the correct answer is cerebral palsy, option (b).
