Experiment: Does reducing muscle tension reduce headaches?

Muscle tension in the head region has been associated with tension headaches. Therefore, a physician reasoned that if the muscle tension could be reduced, perhaps the headaches would decrease or go away altogether. They design an experiment in which nine participants with tension headaches participate. The participants keep daily logs of the number of headaches they experience during a 2-week baseline period. Then they are trained to lower their muscle tension in the head region, using a biofeedback device. For this experiment, the biofeedback device is connected to the frontalis muscle, a muscle in the forehead region. The device tells the participant the amount of tension in the muscle to which it is attached (in this case, frontalis) and helps them achieve low tension levels. After 6 weeks of training, during which the participants have become successful at maintaining low frontalis muscle tension, they again keep a 2-week log of the number of headaches experienced. The following are the number of headaches recorded during each 2-week period.

Participant #	# headaches before training	# headaches after training
1	17	2
2	13	7
3	6	2
4	5	3
5	5	6
6	10	2
7	8	1
8	6	0
9	7	2
