Brief Summary
Forward Head Posture (FHP) causes muscle imbalances in the neck and shoulder regions. Various exercises are suggested to correct FHP. During these exercises, internal and external focus techniques are used to enhance motor learning and improve muscle balance. However, there are no studies examining how these approaches affect neck muscle activation in individuals with FHP. Therefore, the purpose of this study is to investigate the effects of external and internal focus techniques, aimed at improving cervical alignment during postural correction exercises, on cervical muscle activation in individuals with FHP.

Outcome Measures
Primary Outcomes (2)
Electromyography (EMG) Measurement on neck muscles
The activation of the Upper Trapezius (UT), Middle Trapezius (MT), Lower Trapezius (LT), Serratus Anterior (SA), and Sternocleidomastoid (SCM) muscles will be measured using the non-invasive surface 8-channel EMG Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ).
through study completion, an average of 3 months
Craniovertebral Angle Measurement
The craniovertebral angle (CVA) will be measured using the reliable and valid lateral digital photogrammetric method and Kinovea Video Analysis Software. Participants will be filmed laterally from their dominant side (left for left-dominant, right for right-dominant). A phone on a tripod will be placed 1.5 meters away from the participant at shoulder height. Markers will be placed on the tragus and C7 spinous process for accurate measurement, with participants wearing tight shorts and a short-sleeved shirt. They will be instructed to stand with feet shoulder-width apart and face forward. Before photographing, participants will walk in place five times to capture their natural head-body position. Photos will be taken within the first 5 seconds, and the CVA will be measured using Kinovea Video Analysis Software.

Study Arms (6)
unguided scapular retraction
NO INTERVENTIONParticipants will be asked to perform the scapular retraction exercise without any corrective cues for the cervical region.
unguided prone T exercise
NO INTERVENTIONParticipants will be asked to perform the prone T exercise without any corrective cues for the cervical region.
scapular retraction exercise with External focus
ACTIVE COMPARATORFor external focus, participants will wear a headband with a laser light positioned on their forehead. The laser will be aligned to shine above and between the eyebrows. A flat wall will be placed in front of them, where the laser light is clearly visible. Participants will be instructed: "Bring your head into a chin tuck position and focus on the point where the laser hits the wall while performing the exercise."
scapular retraction exercise with internal focus
ACTIVE COMPARATORParticipants will be instructed: "Bring your head into a chin tuck position and focus on keeping your neck in a neutral position while performing the exercise."
prone T exercise with external focus
ACTIVE COMPARATORFor external focus, participants will wear a headband with a laser light positioned on their forehead. The laser will be aligned to shine above and between the eyebrows. A flat wall will be placed in front of them, where the laser light is clearly visible. Participants will be instructed: "Bring your head into a chin tuck position and focus on the point where the laser hits the wall while performing the exercise."
prone T exercise with internal focus
ACTIVE COMPARATORParticipants will be instructed: "Bring your head into a chin tuck position and focus on keeping your neck in a neutral position while performing the exercise."
Interventions
A chin tuck is a posture correction technique where the individual gently tucks their chin towards their chest while keeping the rest of the body straight. This movement helps align the head and neck, reducing forward head posture and improving spinal alignment. After performing the unguided exercises, the patients will be taught the chin tuck position. From this point onward, they will be instructed to maintain the chin tuck position while performing the exercises using both external and internal focus strategies.
