      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Other design features: This randomized clinical trial is of the double-dummy type. in this way, one group will receive deep neck flexor exercises with placebo treatment of myofascial release of suboccipital muscles and the other group will receive myofascial release of suboccipital muscles with placebo treatment of deep neck flexor exercises, Randomization description: All eligible patients with chronic tension-type headache are randomly divided into two groups of treatment: deep neck flexor exercise and myofascial release groups with a 1: 1 ratio. Generatorslist.com is used to determine random allocation; This method is done with the help of four-digit blocks including even and odd numbers. For this purpose, 4-digit numbers are selected that have 2 even digits and 2 odd digits; Each digit represents each participant in the study.
The random allocation process will be performed by someone outside the research team before the study begins. At the end of the random allocation, the numbers will be placed inside the numbered envelopes separately and after the initial evaluation by the examiner, the numbered envelopes will be given according to the ordinal number of each person entered in the study. Finally, after each participant enters the treatment sessions, the therapist opens the envelope of the participants and applies therapeutic interventions based on the number in the envelope.
Patients are told not to provide information about their group to the assessor to prevent data contamination, Blinding description: In this study, participants, the outcome assessor, and, the statistician will be blinded.
 Method of blindness: 
a) Participants: In each of the treatment groups, a real treatment was used with the placebo form of treatment of another group (the first group includes deep neck flexor exercise with placebo myofascial release, and the second group includes suboccipital myofascial release with placebo deep neck flexor exercise) so that the participants could not guess which treatment group they had entered; also, the participants will not be aware of how the other group will be treated.
 B) Outcome Assessor: Outcome assessment will be performed by a person who has no knowledge of the grouping of individuals and the treatments performed in each treatment group.
 C) Statistician: Data analysis will be performed by a person who does not know the grouping of people and the treatments performed in each treatment group.</study_design>
