“…Hence, some authors have suggested that postural control is not a goal by itself, but a means to achieve goals (Mitra & Fraizer, 2004;Riccio & Stoffregen, 1988;Smart, Mobley, Otten, Smith, & Amin, 2004;Smart & Smith, 2001;Stoffregen, Bardy, Bonnet, & Pagulayan, 2006;Stoffregen, Pagulayan, Bardy, & Hettinger, 2000). Along this line, Riccio and Stoffregen (1988) have suggested that postural control is adapted to facilitate performance in one or more on-going tasks.…”

“…Postural control has been defined as a behavior that attempts to maintain a given coordination of body segments without loss of balance in order to facilitate the performance of other actions (Smart and Smith 2001). To maintain this coordination, the body undergoes continuous movement even without the influence of external perturbations (a phenomenon known as 'postural sway'; Carroll and Freedman 1993;Collins and DeLuca 1994).…”

Postural sway was assessed [via center of pressure (COP) 95% elliptical area (EA), path length (PL), normalized path length (PL(n)) and sample entropy (SEn)] in four conditions of bipedal upright stance [compliant (Foam) vs. non-compliant (Hard) with eyes-open (EO) vs. eyes-closed (EC)] prior to, and immediately following, a six-week balance training intervention in a group of healthy adults (N = 26). The intervention was comprised of nine exercises progressed in difficulty based on the subjective assessments of individual competency. Results showed that EA and PL were increased, while PL(n) and SEn were decreased, in EC and Foam stance conditions (collapsed across effects of balance training). Interpretations were that restricted vision and a compliant surface represented constraints to postural control that caused increases in the amount (PL) and area (EA) of sway, but decreases in its coordinative twisting/turning (PL(n)) and temporal complexity (SEn). It was argued that these changes might represent compensatory adaptations in effort to maintain postural control given the demands of the imposed constraints. Balance training caused no change to EA, but did result in decreased PL, PL(n), and SEn for stance conditions performed on the Foam (either EO or EC). These changes were interpreted to reflect improved postural control, potentially through the learned adoption of a more deterministic postural control strategy that is uniquely defined by the constraints imposed on upright stance by the compliant surface.

“…Yaş ilerledikçe bu aktivitelerin uygulanması daha da önem kazanmakta ve özellikle daha kırılgan kemiklere sahip kadınlar için daha etkili egzersiz programları oluşturmaya çalışılmaktadır. Duruş kontrolü, denge kaybı olmadan vücut bölümlerinin belirli bir koordinasyonda hareket edebilmesi olarak tanımlanır [18] ve denge egzersizleri sağlıklı bireylerde duruş kontrolünü geliştirebilir [19]. Denge egzersizlerinin yıldız denge testi mesafesinde artış sağladığını kanıtlayan araştırmalar yanında [7], denge antrenmanlarının duruş kontrolünü geliştirmede başarısız olduğunu ortaya koyan araştırmalar da bulunmaktadır [20,21].…”

ÖZETBu araştırmanın amacı denge diski egzersizlerinin dinamik denge ve duruş kontrolü üzerindeki etkisini incelemektir. Araştırmaya, düzenli bir egzersiz programına devam etmeyen, gönüllü ve sağlıklı toplam 20 kadın üniversite öğrencisi katılmıştır. Kadınlar kontrol (10 kadın) ve egzersiz grubu (10 kadın) olarak ikiye ayrılmış ve kadınların hamle mesafesi, çoklu tek-bacak sıçramadaki denge hata sayısı ve yıldız denge testi mesafeleri egzersizden önce ve sonra ölçülmüştür. Egzersiz grubuna vestibüler denge diski kullanılarak 6 hafta, haftada 3 gün, 50 dakikalık denge egzersizleri uygulanmış, kontrol grubuna egzersiz uygulanmamıştır. Verilerin analizinde; Mann Whitney U testi ve Wilcoxon testi kullanılmıştır. Araştırmanın sonucunda; egzersiz grubunun egzersiz sonrası hamle mesafesinde anlamlı artış bulunmuş (p<0,05), çoklu tek-bacak sıçrama denge hata sayısı ve yıldız denge testi sağ ve sol bacak mesafeleri, egzersiz öncesi ve sonrası değerleri arasında anlamlı fark bulunmamıştır (p>0,05). Egzersiz grubu ve kontrol grubu kıyaslandığında ise, sağ ve sol bacakla öne hamle mesafesi arasındaki fark anlamlı bulunmuş (p<0,05), iki grup arasındaki sağ ve sol bacakla yana hamle mesafesi arası fark anlamlı bulunmamış (p>0,05), sağ ve sol bacak iniş hata sayısı arasında anlamlı fark bulunmuş (p<0,05), sağ ve sol bacak denge hata sayısı arasında anlamlı fark bulunmamıştır (p>0,05). Sağ bacak anterior, anteromedial, medial ve anterolateral yöndeki erişme mesafeleri arasında ve sol bacak anterior, anteromedial, medial, posterolateral, lateral ve anterolateral yöndeki erişme mesafeleri arasında anlamlı fark bulunmuştur(p<0,05). Sonuç olarak, denge diski ile uygulanan 6 haftalık denge egzersizleri dinamik denge ve duruş kontrolünü olumlu yönde etkiler.Anahtar Kelimeler: Çoklu tek-bacak sıçrama denge testi, denge, hamle testi, yıldız denge testi THE INVESTIGATION OF EFFECT OF BALANCE DISC EXERCISE ON DYNAMIC BALANCE AND POSTURAL CONTROL ABSTRACTThe aim of this study was to investigate the effect of balance disc exercise on postural stabilization and dynamic balance. Twenty healthy female university students who were not in a regular exercise program participated in the study voluntarily. The women were divided into two groups as exercise (10 women) and control groups (10 women). Exercise group participated in balance exercise program by using vestibular balance disc for 6 weeks, 3 sessions a week which lasted for 50 minutes. Lunge distance, multiple single-leg hop stabilization error and star excursion balance test distance were measured before and after 6-week exercise program. The control group did not participate in the exercise program. The data were analyzed using The Mann Whitney U and Wilcoxon test. The results showed that there was significant difference between before and post exercise lunge test distances in exercise group (p<0.05). There were no significant differences between before and post-exercise stabilization errors and star excursion balance test distance in exercise group (p>0.05). There were significant differ...
