Investigation of Relationship Between Body Mass Index and Neck Biomechanics in Healty Young Adults: A Cross-Sectional Study in a Single Center

Abstract

Purpose: The aim of this study is to examine the effects of body mass index above normal limits on forward head posture and deep cervical flexor muscle endurance, which are considered to be predisposing factors of mechanical neck pain. Methods: Twenty-four individuals (mean age of 20.50 ± 2.02 years) with a body mass index (BMI) between 19.9 kg /m2 and 24.9 kg /m2 were included in the Normal Body Mass Index (N-BMI group) and 24 individuals with a BMI over 24.9 kg /m2 (mean age of 24.41 ± 2.90 years) were included in the Owerweight-Obese (OW-O group). Cranicervical Angles (CCA) of individuals was measured digitally to determine forward head posture. Deep Cervical Flexor Muscle Endurance Test (DCFMET) was used for endurance of deep cervical flexor muscles. Results: The CCA values of the OW-O group were less than in the N-BMI group, indicating an increased forward head posture (p = 0.043). There was no statistically significant difference in terms of the endurance of the deep cervical flexor muscles between the groups (p = 0.817). A moderate negative correlation was found between the BMI values and CCA of all individuals participating in the study (p = 0.012, r= -0.503). There was no correlation between BMI and DCFMET (p=0.887, r = 0.031). Conclusion: Knowing that overweight and obese young people are in the risk group for mechanical neck pain and various cervical pathologies, plays a very important role in increasing awareness about preventive approaches such as postural correction exercises and weight management strategies.

Sağlıklı Genç Yetişkinlerde Vücut Kütle İndeksi ve Boyun Mekaniği İlişkisinin İncelenmesi: Tek Merkezli Kesitsel Bir Çalışma

Abstract

Amaç: Bu çalışmanın amacı, normal sınırların üzerindeki vücut kitle indeksinin, mekanik boyun ağrısına zemin hazırlayan faktörler olarak kabul edilen baş ileri poziyonu ve derin servikal fleksör kasların enduransı üzerindeki etkilerini incelemektir. Yöntem: Vücut Kütle İndeksleri (VKİ) 19.9 kg /m2 and 24.9 kg /m2 arasında olan yirmi dört birey (ortalama yaş: 20.50 ± 2.02 yıl) Normal Vücut Kütle İndeksi grubuna (N-VKİ grubu), Vücut Kütle İndeksleri (VKİ) 24.9 kg /m2 üzerinde olan 24 birey (ortalama yaş: 24.41 ± 2.90 yıl) Aşırı kilolu-Obes grubuna dahil edildi (AK-O grubu). Baş ileri postürünü tespit etmek için, bireylerin Kranioservikal Açıları (KSA) dijital olarak ölçüldü. Derin servikal fleksör kasların enduransını ölçmek için Derin Servikal Fleksör Kasların Endurans Testi (DSFKE) kullanıldı. Bulgular: AK-O grubunun KSA değerleri N-VKİ grubuna göre statistiksel olarak daha düşüktü (p=0.043). Bu durum da artmış baş ileri postürünü işaret etmekteydi. Gruplar arasında derin servikal fleksör kasların enduransında istatistiksel olarak fark yoktu (p=0.817). Çalışmaya katılan tüm bireylerin VKİ ile KSA değerleri arasında negative yönde orta düzey korelasyon bulundu (p = 0.012, r= -0.503). VKİ ile DSKE arasında bir korelasyon yoktu (p=0.887, r = 0.031). Sonuç: Aşırı kilolu ve obez gençlerin mekenik boyun ağrısı ve çeşitli servikal patolojiler açısından risk grubunda olduğu bilmek, postural düzgünlük egzersizleri ve kilo control stratejileri gibi önleyici yaklaşımlar hakkında farkındalığın artaması için çok önemli bir rol oynamaktadır.
