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.Keywords : Fonksiyonel uzanma, Postüral kontrol, Denge değerlendirmesi, Kararlılık sınırı
