Epidemiological studies have shown that bad posture and poor body control occurs at puberty, with forward head posture (FHP) and rounded shoulders being the most common biomechanical deviations in sagittal plane. The FHP is defined as an anterior displacement of the head with hyperextension of the cervical spine and this is associated with a reduction in the length of the upper portion of the trapezius, posterior portion of the cervical extensor muscles, the sternocleidomastoid and the levator scapulae. FHP can be evaluated by measuring craniovertebral angle (CVA) which is defined as the angle between a horizontal line passing through C7 and a line extending from the tragus of the ear to C7.
CVA, smaller than 50 degrees, constitute a criterion of abnormal posture of cervical spine, suggesting FHP. People with FHP present incomplete balance control, thereby affecting the position of the center of gravity and motor control of the body. The establishment of altered motor control strategies could lead to balance disorders, neck muscle imbalances, chronic neck pain and even respiratory dysfunction.
Despite the efforts of researchers to create effective treatment programs based on strength training and stretching exercises, positive long-term results have been a problem in FHP correction. For this reason, re-education of posture and body alignment, through exercise programs based on motor learning, with cognitive elements (attention, motivation, feedback, reasoning), could be proved a more effective therapeutic strategy.

Inclusion criteria
Exclusion criteria
The exercise program will include simple activities exposing volunteers in various environmental conditions with a view to adjust their head posture in such conditions. The progressiveness of exercises will be based on the two-dimensional classification system of Gentile (1987). Furthermore, external attentional focus will be used.
Time frame: Change from Baseline sFHP at 4 weeks and Change from Baseline sFHP at 6 weeks
The sFHP will be assessed by calculating the craniovertebral angle through lateral photographs in standing. The craniovertebral angle is the angle between the line extending from the tragus of the ear to the 7th cervical vertebra (C7) spinous process and the horizontal line through C7. The calculation of the angle on the photographs will be carried out using AutoCAD software. A performance curve will be developed using the measurements during the 4 weeks practice and 2 weeks after the end of protocol (retension test).
Time frame: Change from Baseline dFHP t at 4 weeks and Change from Baseline dFHP at 6 weeks
The dFHP will be assessed by calculating the craniovertebral angle through video motion during walking. The craniovertebral angle is the angle between the line extending from the tragus of the ear to the 7th cervical vertebra (C7) spinous process and the horizontal line through C7. The calculation of the angle The calculation of the angle will be carried out using Kinovea and AutoCAD softwares. dFHP will be regarded as a transfer test. Transfer tests are tests involving some novel situation, so that people must adapt the skill they have been practicing to the characteristics of this new situation.
Time frame: Baseline; week 4; week 6
Sorensen self-esteem test will be used which has been translated into Greek and has been tested for its reliability and validity.
Time frame: Baseline; week 4; week 6
A ten point Visual Analogue Scale (VAS) will be used
Time frame: Baseline; week 4; week 6
A ten point VAS scale will be used
Time frame: Baseline; week 4; week 6
A ten point VAS scale will be used
Time frame: Baseline; week 4; week 6
Attention- concentration questionnaire will be used. It has been developed in Greek language and has been tested for its reliability and validity.
Time frame: Baseline
The Wechsler Adult Intelligence Scale (WAIS-IV) (similarities) will be used. Participants will be given a number of pairs of words or concepts and have to describe how they are similar.
Time frame: Baseline
The WAIS-IV (Matrix Reasoning) will be used. Participants will be given pictures of sets of drawings and have to choose the correct drawing that is missing from each set.
Time frame: Change from Baseline Deep neck flexors endurance at 4 weeks and Change from Baseline Deep neck flexors endurance at 6 weeks
The first stage of the test allows for the quantification of the performance of craniocervical flexion action, while the second stage examines the isometric endurance of deep neck flexors, during which the participant adopts the crook lying position. The air chamber of a pressure biofeedback device is positioned under the cervical area and the participant is asked to perform a head nod action at five different pressure levels (22, 24, 26, 28 and 30 mmHg). The test is initially performed at a pressure level of 22 mmHg and proceeds to the next pressure level if the participant is able to maintain in the position for 10 seconds on three separate occasions. The Chattanooga stabilizer pressure biofeedback will be used.
Time frame: Change from Baseline discomfort at 4 weeks and Change from Baseline discomfort at 6 weeks
The Discomfort will be assessed using a ten point grade VAS scale, where 0 is no pain and 10 worst pain.
Time frame: Change from Baseline discomfort at 4 weeks and Change from Baseline discomfort at 6 weeks
The Discomfort (Head, Neck, Shoulders and upper arms, Middle back, Lower back, Forearms and Wrists/hands areas) will be assessed using a body chart
Time frame: Baseline
Measurement of weight with scale (kilograms)
Time frame: Baseline
Measurement of height (cm)
