Abstract

Purpose: The aim of this study was to determine differences in lower extremity coordination and motor control between overweight and normal individuals and to reveal the reasons in deficiency of balance and stability which was observed in obesity when the negative effect of gravity on balance was eliminated. Methods: Twenty subjects were divided into two groups according to their body mass index (BMI) (overweight: BMI 29.73±3.07 kg/m² and normal: 21.38±1.10 kg/m²) which was determined using bioelectrical impedance analysis. Multi-joint lower-limb tracking-trajectory test was performed to determine the motor control and coordination deficits. Ankle joint bimalleolar diamater and circumference were measured to determine whether presence of any morphological differences which could affect motor coordination outcomes in lower extremity. Results: There were no significant differences between two groups in concentric and eccentric motor coordination, ankle joint bimalleolar diamater and bimalleolar circumference (p>0.05). Conclusion: The results of our study demonstrated that there was no difference in lower extremity motor coordination between overweight and normal individuals when the effect of body mass and gravity was eliminated. Outcomes of this study reinforce the theory that any sensory related problem is not the reason of postural instability in obese individuals. The deficiency may result from biomechanic influence of excess body mass.

Özet

Amaç: Bu çalışmanın amacı obez bireylerin denge ve koordinasyon testlerinde gösterdiği eksikliğin, yer çekiminin denge üzerine bozucu etkisi yok edildiğinde de oluşup oluşmadığını ortaya çıkarmak; böylece obez bireylerde gövde stabilitesinde gözlenen zayıflığın nedenini ve oluş mekanizmasını ortaya koymaktı. Yöntem: 20 birey, vücut ağırlıkları ve vücut yağ yüzdeleri bioelektriksel impedans analizi ile ölçülerek vücut kütle indeksine (VKİ) göre fazla kilolu (VKİ: 29.73±3.07 kg/m2) ve normal kilolu (VKİ: 21.38±1.10 kg/m2) olmak üzere 2 gruba ayrıldı. Her iki grupta alt ekstremitede nöromusküler koordinasyonu belirlemek amacıyla horizontal leg press aleti üzerinde bilgisayarlı hedef takip testi yapıldı. Ayak bileği bimalleolar çap ve bimalleolar çevre ölçümleri yapılarak gruplar arasında, koordinasyon testi sonucunu etkileyebilecek yapısal farklılık olup olmadığı belirlendi. Sonuçlar: Hedef takip testi eksentrik koordinasyon ve konsentrik yönde koordinasyon sonuçlarında, bimalleolar çap ve bimalleolar çevre ölçümü sonuçlarında iki grup arasında istatistiksel açıdan fark bulunamadı (p>0.05). Tartışma: Vücut ağırlığının etkisi yok edildiğinde, obez bireyler ile normal bireyler arasında, alt ekstremite motor kontrol ve koordinasyon açısından her hangi bir farklılık yoktur. Bu sonuç literatürde obez bireylerde gösterilen denge ve gövde stabilitesi eksikliğinin nedeninin; algısal derin duyu eksikliğinden daha çok, vücut ağırlığının mekanik etkisi nedeniyle oluştuğu teorisini güçlendirmektedir.
