In a previous study, 30 pregnant women suffering from headaches were t
reated with physical therapy, relaxation training, and biofeedback. Ei
ghty percent of these women experienced significant relief of headache
s following treatment. Although this study demonstrated the effectiven
ess of nonmedical treatment during pregnancy, little is known about th
e influence of changing hormones during pregnancy on fluctuations in h
eadache. One purpose of this study was to present a follow-up of the w
omen who were included in the previous study to determine whether the
results from the nonmedical treatment were maintained up to a year aft
er giving birth. In addition, this study examined the influence of hea
dache diagnosis and breastfeeding on changes in headache activity and
maintenance of treatment effects. The results indicate that the reduct
ions in headache activity were maintained at follow-up in the majority
of the women treated, with 67.5% of the sample maintaining a signific
ant decrease in headache up to 1 year after giving birth. Neither IHS
diagnosis nor breastfeeding was related to maintenance of headache imp
rovement. We conclude that the beneficial effects of nonpharmacologica
l treatment of headaches during pregnancy demonstrated in a previous s
tudy are maintained up to 1 year following delivery. Headache diagnosi
s and breastfeeding were not related to treatment outcome, a finding t
hat contradicts the reports of many retrospective studies.
