The control group refers to patients with tension-type headache who will not be treated. These patients are only evaluated during follow-up.

Patients with tension-type headache in the study group are treated. Evaluations are made before and after treatment.

Facial Distortion is a manual therapy technique applied by model physiotherapists. It is a deep tissue massage to the fascial tissue.

The McGill Pain Scale will be used to assess the pain of individuals. The questionnaire consists of four different parts. In the first part, in order to determine the localization of pain. In the second part, there are 20 word groups to be marked to determine the nature of the pain. In the fourth part of the scale, the patient is asked to choose appropriate words to determine the severity of pain. The higher the score, the greater the severity of the pain.

Pain intensity will be evaluated with the Visual analog scale (VAS). VAS consists of a 10 cm long horizontal line. '0' means no pain, '10' means unbearable pain. For evaluation, the patients were asked to mark the level of pain they felt on this line, and the distance to the starting point was measured with a ruler and the severity of the pain was recorded. The higher the score, the greater the severity of the pain.

Laser cursor assisted angle repetition test will be used to evaluate cervical joint position sense. The patient is positioned to coincide with the origin point of the laser target table. The patient is first asked to aim at the origin of the target pane with his eyes open. The distance from the point where the patient is standing to the origin is measured in cm. As the deviation distance increases, the sense of joint position worsens.

Posturescreen mobile (PostureCo Inc., Trinity, FL, USA) application will be used for cervical posture assessment. Posturescreen Mobile (PSM) is a new photographic mobile application for detecting deviations from ideal posture.The validity and reliability study of the (PSM) application was conducted (118). As a reference point, the canthus of the eye, tragus, 7th cervical vertebra, and acromion will be marked on the photograph by the physiotherapist. Craniovertebral angle and shoulder position angle obtained automatically from the application will be recorded. Forward head posture increases with decreasing craniovertebral angle. The increase in shoulder position angle shows that protraction also increases.
