Denne nevner at Forward Head Posture gir en større spenning i trapzius når man løfter hendene. For å få trapzius og nakkespenninger til å slappe av må man altså få hodet tilbake i nøytral posisjon.

Significantly increased EMG activity in the upper trapezius and lower trapezius and significantly decreased EMG activity in the serratus anterior were found during loaded isometric shoulder flexion with FHP. Thus, FHP may contribute to work-related neck and shoulder pain during loaded shoulder flexion while sitting.

These results suggest that maintaining NHP is advantageous in reducing sustained upper and lower trapezius activity and enhancing serratus anterior activity as compared with FHP during loaded shoulder flexion.
