Figure 2. Pain modulation response at baseline relates to headache frequency reduction after cognitive behavioral therapy (CBT).

Figure 2.

Greater reduction in headache frequency was related to lower conditioned pain modulation (CPM) response before CBT at the trapezius (r =0.492, p = 0.028, n=20) but not at the leg (r = 0.240, p = 0.309, n=20).
