Background. Headache is one of the most common causes of consultation in primary health care and neurology in Europe. Cervical muscle tension can maintain a restriction of joint motion at the suboccipital level, facilitating the referred head pain. Objective. To evaluate the effectiveness of two manual therapy treatments for tension-type headache. Methods. A randomized double-blind clinical trial was conducted, for a period of 4 weeks and a follow-up at one month post-treatment. Eighty-four patients with tension-type headache were assigned to 4 groups (3 treatment groups and 1 control group). Treatments included manual therapy of suboccipital soft tissue inhibition, occiput-atlas-axis global manipulation, and a combination of both techniques. Outcome measures were: impact of headache, disability caused by headache, ranges of motion of the craniocervical junction, frequency and intensity of headache, and associated headache symptoms. Results. After 8 weeks, there were significant improvements in impact of headache (p=0.01), disability (p=0.001), and craniocervical flexion (p=0.03) for the suboccipital soft tissue inhibition group; in headache impact and disability (p=0.000), pain intensity (p=0.02) and craniocervical flexion (p=0.004) and extension (p=0.04) for the occiput-atlas-axis group; and in impact (p=0.002), functional disability (p=0.000), headache frequency (p=0.002) and intensity (p=0.001), craniocervical flexion (p=0.008) and extension (p=0.003) and associated headache symptoms (p=0.01) for the combined therapy group, with effect sizes from medium to large. Conclusions. Occiput-atlas-axis and combined therapy group treatments are more effective than suboccipital soft tissue inhibition for tension-type headache. The treatment with suboccipital soft tissue inhibition, despite producing less significant results, also has positive effects on different aspects of headache.

All patients were assessed in the same conditions before the treatment, after the treatment (at 4 weeks), and at follow-up (after 8 weeks). Four treatment sessions (one session per week). Prior to each treatment session, the physiotherapist performed the vertebral artery test bilaterally, followed by a two-minute neck massage without lubricants and with no proven therapeutic effect, as a placebo for all study groups. The SI treatment aims to release the suboccipital muscle spasm10 that maintains the occiput-atlas-axis joint dysfunction. This technique, which was administered for 10 minutes, uses a deep and progressive gliding pressure applied with the fingertips towards the posterior arch of atlas.

Prior to each treatment session, the physiotherapist performed the vertebral artery test bilaterally, followed by a two-minute neck massage without lubricants and with no proven therapeutic effect, as a placebo for all study groups. The OAA manipulation was bilaterally administered and it attempts to restore the motion dysfunction of this complex. It is a structural technique performed on a vertical line along the odontoid process of axis; neither flexion nor extension is used, and lateroflexion is minimal.
All patients were assessed in the same conditions before the treatment, after the treatment (at 4 weeks), and at follow-up (after 8 weeks). Four treatment sessions (one session per week). Prior to each treatment session, the physiotherapist performed the vertebral artery test bilaterally, followed by a two-minute neck massage without lubricants and with no proven therapeutic effect, as a placebo for all study groups. The combination of both treatments aims to determine whether this combination has greater effects than the separate application of each treatment. After receiving the treatment, the subjects in the experimental groups stayed for five minutes in the supine resting position, in neutral ranges of cervical flexion, extension, lateral flexion and rotation.

The control group received four sessions of placebo treatment, followed by ten minutes of resting position.

Firstly, an individual clinical interview was conducted to collect socio-demographic data and characteristics of headache in a one-month base period (the previous 4 weeks)
This interview gathers information about age, sex, intensity and frequency of headache (with a Visual Analog Scale from 0 to 10), severity of pain (low, moderate, high), qualities of pain (Bilateral location of pain, Pulsating pressure, Not aggravated by physical activity, Photofobia/Phonofobia, Nausea/Vomiting, Pericranial tenderness), cranial location of pain, family history of headache, triggers, aggravating and pain-relieving factors, as well as any previous physiotherapy treatment for headache relief.
Time frame: up to 4 weeks
Impact of headache on daily life(HIT-6)
It consists of 6 items each with 4 response options ranging from "never" (6 points) to "always" (13 points), and has shown high reliability in previous studies (alpha 0.87).
Time frame: up to 8 weeks
Headache Disability Inventory (HDI)
Two first items concerning the frequency and intensity of headaches and a questionnaire of 25 items assessing emotional and functional aspects with 4 possible response options, with an alpha reliability of 0.76-0.83
Time frame: up to 8 weeks
Headache pain intensity
rated daily by the patient on the 0-10 Visual Analogue Scale (VAS) (0 = no pain, 10 = most severe pain).
Time frame: up to 8 weeks
Ranges of motion of the craniocervical junction
measured with the CROM-device. This instrument has demonstrated a good intra-tester reliability for the movements of cervical flexion, extension, lateral flexion and rotation (ICC \> 0.80) (ICC\>0.80). However, not having found any previous studies about its reliability for the craniocervical junction (upper cervical joint), we performed -before using this device in our study- an inter-tester reliability analysis with our two examiners and 10 patients not participating in this study, which showed a Pearson's correlation of 0.98
Time frame: up to 8 weeks
Headache diary
During the four-week treatment period and in the follow-up phase, patients recorded on a daily basis the characteristics of headache with data regarding headache frequency and intensity, associated headache symptoms of photophobia or phonophobia, nausea or vomiting, and pericranial tenderness, completing a total of 7 weekly records.
Time frame: up to 8 weeks
