Relaxation training probably reduces chronic headache and migraine in children and adolescents.
Relaxation is probably as effective as other non-pharmacological interventions.
There appear to be long-term benefits. Based on one trial, biofeedback with relaxation training reduced migraine. It is not possible to say whether the addition of biofeedback increased the benefits of relaxation or not. Larger, randomised trials are required to provide definitive answers. A range of pharmacological and non-pharmacological approaches were tested in the management of paediatric headache, with mixed findings.
