###### Abstract  
The Functional Gait Assessment (FGA) was cross-culturally adapted into Greek, according to international guidelines. The final Greek version of the scale (FGA\({}_{\text{GR}}\)) was evaluated for its reliability and was correlated with the mini-Balance Evaluation Systems Test (mini-BESTest), the Berg Balance Scale (BBS), the Timed Up and Go (TUG) test, and the Falls Efficacy Scale-International (FES-I) questionnaire, for testing the concurrent validity. The discriminant validity between individuals reporting low and those reporting high concern about falls as well as the predictive validity in identifying people with high risk of falls were assessed. The FGA\({}_{\text{GR}}\) was characterized as comprehensible in its content and orders. Psychometric testing in 24 Greek-speaking individuals (six men and eighteen women, \(66\pm 7\) years old) yielded excellent test-retest (ICC = 0.976) and inter-rater reliability (ICC = 0.984), but moderate internal consistency (Cronbach's alpha = 0.660). The FGA\({}_{\text{GR}}\) scale proved its concurrent and discriminant validity while a maximum cutoff point of 25, with sensitivity of 84% and specificity of 100%, was identified to be optimal for predicting risk of falls in the elderly. The good psychometric characteristics of the FGA\({}_{\text{GR}}\) confirm its applicability in assessing gait of Greek-speaking older adults.

the decrease in speed, the increase in the double-stance phase time, the widening of the support base, and the decrease in stride length [5]. Additional changes are evident in spatiotemporal gait parameters, with the most eminent being the unsteadiness in the dark and on uneven surfaces, and the impaired dual-tasking ability while walking [6]. The aforementioned implications indicate the importance and necessity of a correct and comprehensive assessment of gait and balance in the elderly. By identifying deficits and organizing a treatment plan, falls might be prevented and the elderly would maintain their autonomy, their functionality, and their quality of life [8; 9]. A variety of assessment methods for gait and balance are available [10; 11; 12]. The functional scales have the advantage of being easily applicable in the clinical environment and providing reliable and valid records of the ability of the person to perform simple daily activities [13]. The FGA has been specifically developed by [PERSON] et al. as a modified form of the DGI in order to assess balance during gait in people with vestibular disorders [14]. Since then, it has been extensively used in other populations, such as in older adults [15; 16], in Parkinson's disease [17], in multiple sclerosis [18], in stroke [19], and in incomplete spinal cord injury [20]. It is a 10-item scale which assesses gait in ten different functional conditions: with normal and alterations in speed, under vertical and horizontal head turns, over obstacles, with pivot turns, on stairs, in a narrow base of support, with eyes closed and walking backwards [14; 21; 22]. The application of the scale takes only 10 min, and it requires very simple and easy to find equipment, such as two shoe boxes, some steps, and a free 6 m walkway of 30.48 cm width, marked at its beginning and end [14]. The original FGA has presented high inter- and intra-rater reliability as well as internal consistency [14]. Its relation to other balance and gait tests, such as the Activities-Specific Balance Confidence Scale (ABC), Dizziness Handicap Inventory (DHI), Perception of Dizziness Symptoms (PDS), Timed Up and Go (TUG) test, and Dynamic Gait Index (DGI), was moderate [14; 22]. The FGA has presented its discriminant and predictive validity in classifying risk of falls in older adults and predicting falls in community-dwelling older adults at a cutoff score of 22/30 [16].
