Abstract

Amaç: Baş önde postür (BÖP) bozukluğu yaygın bir postüral problemdir. Bununla birlikte, yürüyüş kinematiği üzerindeki etkisi belirsizliğini korumaktadır. Bu çalışmanın amacı, genç yetişkinlerde baş postürünün yürüyüşün spatio-temporal parametreleri ve asimetrisine etkisini araştırmaktır.
Gereç ve Yöntem: Genç erişkinlerde gerçekleştirilen bu kesitsel çalışmada katılımcılar kraniovertebral açı (KVA) değerine göre BÖP ve normal postür olmak üzere iki gruba ayrıldı. Katılımcıların KVA, kranial rotasyon açısı ve kraniohorizontal açıları lateralden çekilen fotoğraflar ile değerlendirildi ve MB-Ruler yazılımı ile analiz edildi. Katılımcıların demografik bilgileri (cinsiyet, yaş, boy, kilo) kaydedildi ve yürüyüş spatiotemporal parametreleri—ilk temas, destek, sallanma fazları, adım döngüsü, dinamik basınç ve yürüyüş simetri skorları—FreeMED force platformu (Sensor Medica, İtalya) kullanılarak ölçüldü. Yürüyüş simetrisi simetri indeksi kullanılarak hesaplandı.
Bulgular: Çalışmaya ortalama yaşları 23 yıl (22-23 ÇAA) olan 66 katılımcı (41 kadın ve 25 erkek) dahil edildi. Sol adım döngüsü uzunluğu ile kranial rotasyon açısı arasında orta düzeyde pozitif bir ilişki bulundu (r=0,316, p=0,024). Ancak, gruplar arasında diğer yürüyüş kinematik parametrelerinde anlamlı fark bulunmadı (p>0,05). Ayrıca, CVA ile yürüyüş spatio-temporal parametreleri veya yürüyüş simetrisi arasında anlamlı bir korelasyon bulunmadı (p>0,05).
Sonuç: Baş önde postürün genç yetişkinlerde kinematik spatio-temporal yürüyüş parametrelerini ve yürüyüş simetrisini önemli ölçüde değiştirmediğini göstermektedir. Daha hassas ölçümler sağlayabilecek üç boyutlu postür ve yürüme analizi yöntemleri ile planlanan çalışmalara ihtiyaç vardır.
Anahtar Kelimeler: Kraniovertebral açı, baş önde postür, yürüyüş, simetri.

Does Head Posture Alter Gait Parameters and Symmetry in Young Adults with Forward Head Posture? A Cross-Sectional Study

Abstract

Objective: Forward head posture (FHP) is a common postural problem. However, its influence on gait kinematics remains unclear. The purpose of this study was to investigate the effect of head posture on gait spatiotemporal parameters and asymmetry in young adults.
Material and Method: A cross-sectional study was conducted on young adults categorized into two groups: FHP and normal posture, based on the cut-off value of the craniovertebral angle (CVA). The CVA, cranial rotation angle, and cranial horizontal angle were calculated using lateral photographs and analyzed using MB-Ruler software. Demographic information, including gender, age, height, and weight, was recorded, and gait spatio-temporal parameters—initial contact, support, swing, step phases, dynamic pressure, and gait symmetry scores—were measured using the FreeMED force platform (Sensor Medica, Italy). Gait symmetry was calculated using the symmetry index.
Results: A total of 66 participants (41 females and 25 males) were included in the study, with an average age of 23 (22–23 IQR). There was a moderate positive correlation between left step cycle length and cranial rotation angle (r=0.316, p=0.024). However, no significant differences were determined in other gait kinematic parameters between groups (p>0.05). Additionally, no significant correlation was found between CVA and gait spatiotemporal parameters or gait symmetry (p>0.05).
Conclusion: The findings suggest that FHP does not significantly alter kinematic spatiotemporal gait parameters and gait symmetry in young adults. Research is required to investigate three-dimensional posture and gait analysis methods that can provide more accurate measurements.
