Modification of combined migraine-muscle contraction headaches using BVP and EMG feedback.

Two adults with mixed migraine-tension headaches got biofeedback. One got blood-volume-pulse (BVP) feedback to shrink swollen head vessels. The other got EMG feedback to relax tight forehead muscles.

The team used a multiple-baseline design. Training started at different times to show the feedback, not luck, caused change.

Each person learned to control the body response that matched their pain. The migraine patient cut headache days when BVP scores improved. The tension patient cut headache days when EMG levels dropped.

Headaches dropped only after their own feedback began, proving the right tool for the right pain works.

Bloomfield (1966) first proved tiny muscle signals can be shaped by feedback. T et al. moved that lab trick into real headache relief twelve years later.

McCook et al. (2025) took the same EMG relax idea and gave it to kids with autism. A short video PMR boosted desk work, showing the principle spans ages and goals.

Mann et al. (1971) showed skin responses can be operantly conditioned. T et al. did the same for blood vessels and muscles, widening the list of body parts behavior analysts can tune.

You can match the biofeedback channel to the headache type you see. Try BVP feedback when pain pulses with the heartbeat. Try EMG feedback when the scalp feels tight. Start with five-minute sessions and track headache days on a calendar. If it works for one client, teach them to buy a cheap home sensor so they can self-manage flare-ups.
