Final answer:
Acupuncture is the means of pain control based on the gate control theory, utilizing the concept of gates in the spinal cord that manage pain signals.
Step-by-step explanation:
The means of pain control based on the gate control theory is d) Acupuncture. The gate control theory suggests that there are 'gates' in the spinal cord that control the flow of pain signals to the brain. Techniques like acupuncture are thought to stimulate certain nerves in the body, which then affects the gate mechanisms and may help in reducing the perception of pain. Acupuncture involves inserting needles into specific points on the body, which is believed to release endorphins and block pain signals. Therefore, it can interrupt pain pathways by affecting the way pain is felt and processed by the body.
