5.1 Functional Balance
5.1.1 Berg Balance Scale (BBS)
The results of this study showed that the mean BBS scores of both groups increased after the exercise. The mean BBC score increased 6.3 points in the control group and 5.3 point in the experimental group. These results suggested that both exercise programs could improve functional balance in elderly with fall risks. These changes in the average BBS score were clinically significant. These results agreed with previous study by Stevenson .He suggested that minimal change of 5 points on the total BBS score reflects the genuine change in function balance.
