In the infant Motor Response scale, which score corresponds to 'Spontaneous' movement?

• A. Six
• B. One
• C. Five
• D. Four

Answer: (A)

The key idea is that spontaneous movement is the highest level on the infant Motor Response scale. When an infant moves on their own, without any prompting or external stimulation, it shows the strongest, most intact motor function for their age. This spontaneous activity stands in contrast to movements that only occur in response to touch or sound, or are limited or absent. So the top score on the scale corresponds to spontaneous movement, indicating the best possible motor response on this scale.
