Effects of physical therapy and relaxation techniques on the parameters of pain in university students with tension-type headache: A randomised controlled clinical trial

Abstract

IntroductionNon-pharmacological treatments help control tension-type headache (TTH); however, evidence about their effectiveness is still limited. This study evaluates the effectiveness of physical therapy based on cervical spine kinesiotherapy and posture correction exercises compared to a programme of relaxation techniques only (Schultz's Autogenic Training, AT). MethodsTTH is very common among university students. We randomly selected 152 university students with a diagnosis of TTH according to the criteria of the International Headache Society. Eighty-four were women (55.3%) and 68 were men (44.7%). Mean age was 20.42±2.36 years. The study design is a randomised controlled trial of a non-pharmacological intervention with a blinded evaluation of response variables. We compared the results of two independent samples: AT was used in one of the groups while the other group received AT plus cervical spine kinesiotherapy and posture correction training. Patients recorded any changes in the parameters of pain (frequency, intensity, and duration) and drug consumption in a headache diary before treatment, at 4 weeks, and at 3 months. ResultsBoth interventions achieved a decrease in all the parameters of pain; however, decreases in frequency and intensity were more significant in the combined treatment group (P<0.01) (d=0.4). ConclusionsSuch active, non-invasive therapies as AT and cervical spine kinesiotherapy, and especially the combination of both, effectively reduce TTH by preventing and managing the potential psychophysical causes of this disorder. Future research should aim to assess the long-term effects of these interventions.
