Alternatif bir postüral kontrol testi: modifiye edilmiş fonksiyonel uzanmanın kararlılık sınırları ile korelasyonu

Abstract

Amaç: Fonksiyonel Uzanma Testi (FUT) ve modifiye edilmiş versiyonlarının (mFUT) Kararlılık Sınırları (KS) sonuçlarıyla korelasyonunu değerlendirmek ve postüral kontrol değerlendirmesinde kullanılacak en uygun test yöntemini belirlemekti. Yöntem: Çalışmaya 46 katılımcı dahil edildi. Katılımcılar FUT ve mFUT'ları uyguladılar. Bunlar: Sert zemin dominant kol FUT (SDFUT), Sert zemin çift kol FUT (SÇFUT), yumuşak zemin dominant kol FUT (YDFUT), yumuşak zemin çift kol FUT (YÇFUT) ve sert zemin lateral FUT (sağ-sol). KS testi statik posturografi ile yapıldı. FUT ve mFUT'lerin KS parametreleri ile korelasyonu, ulaşma mesafesi ve hareket süresi parametreleri ile değerlendirildi. Bulgular: SÇFUT ve KS-I (ileri yön) ulaşılan son nokta ile maksimum son nokta (sırasıyla p<0,001, r=0,690; p<0,001, r=0,649) arasında güçlü bir pozitif korelasyon bulundu. YDFUT'deki hareket süresi ile KS-I'deki hareket hızı arasında negatif orta düzeyde bir korelasyon elde edildi (p=0,011; r=-0,463). Sonuç: SÇFUT’un postüral kontrol ölçümlerinde kullanılacak en uygun versiyon olduğunu ortaya koyduk. Ayrıca postüral kontrolde hareket süresini değerlendirmek için posturografinin uygulanamadığı durumlarda YDFUT kullanılabilir.

An alternative postural control test: Correlation of modified functional reach with limits of stability

Abstract

Purpose: To evaluate the correlation of Functional Reach Test (FRT) and its modified versions (mFRTs) with the outcomes of Limits of Stability (LoS), and to identify the most appropriate test method to use in postural control assessment. Methods: Forty-six participants were included in the study. The participants performed FRT and mFRTs: firm ground dominant arm (FRT), firm ground both arms (FRTFB), soft ground dominant arm (FRTSD), soft ground both arms (FRTSB) and firm ground lateral FRTs. LoS was carried out with static posturography. The correlation of FRT and mFRTs with LoS parameters was evaluated as reaching distance and movement time. Results: A strong positive correlation was found between FRTFB and LoS-I (forward direction) endpoint excursion and maximum excursion (p<0.001, r=0.690; p<0.001, r=0.637), respectively. A negative moderate correlation was obtained between the movement time in FRTSD and the movement velocity in LoS-I (p=0.011; r=-0.463). Conclusion: We revealed that FRTFB is the most suitable version to be used in postural control measurements. Besides, to evaluate the movement time in postural control, FRTSD may be used when posturography is not applicable.
