Forward Head Posture (FHP) is a common postural deviation among adolescents, often resulting from prolonged screen use and poor ergonomic habits. It is characterized by an anterior positioning of the head relative to the vertical midline of the body, leading to altered cervical spine mechanics and muscle imbalances. One of the key consequences of FHP is the reduced endurance of deep neck flexor muscles, which play a crucial role in cervical stability and postural control.

Cervical muscle stabilization exercises and proprioceptive training are two widely used interventions aimed at improving neuromuscular control and endurance of cervical muscles. While both methods have shown benefits in postural correction, their relative effectiveness in enhancing neck flexor endurance in adolescents with FHP remains unclear.

This study aims to compare the effects of cervical muscle stabilization versus neck proprioception training on the endurance of deep neck flexors in adolescents with Forward Head Posture.
