Brief Summary:

Objective. To compare the benefits of spinal manipulation combined with massage therapy versus massage alone in patients with tension-type headache (TTH) on the frequency, intensity and disability caused by headache and on cervical range of motion.

Method. A factorial, randomized, double-blinded, placebo-controlled clinical trial was conducted with a sample of 105 subjects diagnosed with TTH, divided into two groups: a) the treatment group received a manipulative technique followed by massage of the cervical and suboccipital region; a) the control group received massage alone. Four sessions (once per week) were applied over four weeks. The Headache Disability Inventory (HDI) was used to evaluate changes in the frequency and severity of headache and functional and emotional aspects of headache. Range of upper cervical and cervical flexion and extension were evaluated. Measures were conducted at baseline, immediately after the intervention (week 4) and at a follow up 8 weeks after completion of the intervention.

Detailed Description:

MATERIALS AND METHODS Participants The sample consisted of 105 people diagnosed with frequent (47.6%) and chronic (52.4%) TTH derived from two primary care centres, selected according to the criteria of IHS3,4, and suffering from headache for more than three months. Participants were aged between 18 and 65 years (mean ± SD: 38.9 ± 10.9 years), which included 23 men (21.9%) and 82 women (78.1%). Patients were excluded if they had suspected malignant disease, rheumatoid arthritis, pregnancy, vertigo, continuous intake of prescribed medication or those who received physical therapy in the past 3 months for headache or neck pain. Finally, 102 subjects completed the study (2 from the treatment group dropped out due to work problems and one from the control due to lack of improvement).

The software G*power14 was to calculate the required sample size, using data from previous studies to estimate the effect sizes to be expected. Our review of the extant literature showed that across studies, the mean N was 44.28 and in general large effect sizes were found (Cohen's d = .40).15-19 We accepted a 5% alpha risk (α = .05) and 10% beta risk (β = .1) as study parameters which showed that 51 subjects were required in each group to achieve a medium-to-large effect size (f = .35). We predicted a 5% dropout rate in the follow-up period.

Study design The study was a factorial, randomized, double-blinded, placebo-controlled clinical trial. It was conducted from January to November, 2014. After the initial clinical interview, the allocation of patients to control or treatment groups was randomized by an external assistant using a specific software (name) who monitored the sequence and documentation at all times. Both the external assistant and the therapist and examiner were blinded to the study objective.

Patients were randomly assigned into 2 groups (treatment and control). The treatment group received occiput-atlas-axis manipulation (OAA) and soft tissue treatment by massage. The control group received massage only. Thus both groups received the same duration of massage therapy and the exposure times were the same, however the difference between groups lay in the manipulative OAA technique which only the treatment group received. Four sessions were conducted (once per week) and the assessment was carried out in 3 stages: at baseline, end of treatment (at 4 weeks) and follow-up at 8 weeks following completion of treatment. All patients in both groups were assessed under the same conditions before and after the treatment by an examiner blinded to the group allocation.

The study was conducted at the University of Valencia (Spain) from January 2014 to November 2014. Prior to data collection, informed written consent was obtained from all patients, and all procedures were conducted according to the Declaration of Helsinki.

Arm Intervention/treatment
Active Comparator: Massage
A superficial massage was performed for 10 minutes in the cervical region consisting of gentle rubbing and kneading.
Other: Massage
A superficial massage was performed for 10 minutes in the cervical region consisting of gentle rubbing and kneading, five minutes prone and five minutes supine with a focus on cervical and suboccipital muscles in order to induce a global relaxation of the cervical and suboccipital region. Resting position. After the treatment, both groups rested for 10 minutes in a supine position with neutral ranges of neck flexion, extension, lateral flexion, and rotation.
Other Name: Active Comparator

Experimental: Occiput-Atlas-Axis Technique
The technique is applied in two stages: in the first stage, a light core decompression is performed and then small circumductions are made with the aim of increasing viscoelasticity of tissues. Subsequently the appropriate joint barrier is sought by selective tension and high-velocity rotation manipulation is performed in a cranial helical motion without raising the subjects head.
Other: Occiput-Atlas-Axis Technique
This technique was applied as described previously and is used with the aim of restoring joint mobility between the occiput, atlas and axis. It is a structural technique applied bilaterally, performed on a vertical axis passing through the dens process of the axis without extension or flexion and very little side-bending. After the treatment, both groups rested for 10 minutes in a supine position with neutral ranges of neck flexion, extension, lateral flexion, and rotation.
Other Name: Experimental




Primary Outcome Measures :
  1. Headache Disability Inventory (HDI). [ Time Frame: 8 weeks ]
    An inventory of disability caused by headaches developed by Jacobson et al. and Gary et al. was used. The purpose of the scale is to identify the difficulties the patient may experience due to headache. It includes 2 items: headache severity (mild, moderate and severe) and frequency (once a month, more than once and less than 4 times a month, and once a week) and 25 items that assess two subscales (E = Emotional with 13 items and F = Functional, with 12 items). Subjects answer each question (yes = 4 points, sometimes = 2 points or no = 0 points). The maximum disability score in this inventory is 100 points. The Spanish adaptation was performed by Rodríguez et al. in 2000, and provides a good index of internal consistency (Cronbach 0.94).


Secondary Outcome Measures :
  1. Cervical range of motion [ Time Frame: 8 weeks ]
    A cervical range of motion (CROM) device was used to assess range of motion of the cervical spine. Higher inter-tester reliability for the CROM is reported for measures of the upper cervical spine ICC> = 0.89. To assess upper cervical flexion and extension, the patient was standing with the back against the wall, looking forward horizontally and performed upper cervical flexion and extension guided by the examiner. For the assessment of cervical flexion and extension, the patient was seated and performed the movements whilst the examiner placed one hand on the sternum and the other over the upper thoracic region to minimise compensatory movements.
