The chin tuck posture: 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.
Study 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.

Primary outcome measure(s)
Electromyography (EMG) Measurement on neck muscles — through study completion, an average of 3 months 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).
Craniovertebral Angle Measurement — through study completion, an average of 3 months 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.
