Abstract :Purpose: To evaluate the correlation of Functional Reach Test insert ignore into journalissuearticles values(FRT); and its modified versions insert ignore into journalissuearticles values(mFRTs); with the outcomes of Limits of Stability insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(FRT);, firm ground both arms insert ignore into journalissuearticles values(FRTFB);, soft ground dominant arm insert ignore into journalissuearticles values(FRTSD);, soft ground both arms insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(forward direction); endpoint excursion and maximum excursion insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
