      <i_freetext>Intervention 1: Volunteer sits on the stool in erect posture and examiner measures the thickness of the neck extensor muscles in this position by means of ultrasonography. Intervention 2: Volunteer sits on an unstable surface (swiss ball), in erect posture and examiner measures the thickness of the neck extensor muscles in this position by means of ultrasonography. Intervention 3: Volunteer sits on an unstable surface (swiss ball) in erect posture and then brings up her upper limbs in a diagonal flexion pattern to a certain point and keeps it and examiner measures the thickness of the neck extensor muscles in this position by means of ultrasonography. Intervention 4: Volunteer sits on the stool and dumbbell at hand and then brings up her upper limbs in a diagonal flexion pattern to a certain point and keeps it and examiner measures the thickness of the neck extensor muscles in this position by means of ultrasonography.</i_freetext>
