5 DISCUSSION AND CONCLUSIONS
5.4 R ECOMMENDATIONS FOR FUTURE RESEARCH
With above-mentioned limitations of this study, future research is obviously needed in a number of directions, but this is a fascinating beginning to understand the effect of floor materials change on gait stability. It would be beneficial to replicate this study with more and different floor types. In order to present the general indoor floor condition of residence, more floor materials with different COFs should be included to increase the variability of floor combinations. With a wider range of COFs, a safer range of COF-difference in two contiguous floor materials could be determined. Furthermore, the relationship between COF-difference and gait stability would be revealed. To understand more about the effect of floor transition on gait stability in difference age group, we need to repeat the study on larger populations. We also intend to examine gender differences in gait control when encounter floor transition condition.
An additional interesting avenue of investigation is whether the color contrast of two continuous floors would influence the performance of locomotion or decision making for gait adjustments. Since visual feedback plays an important role in motor control, further investigations on the effects of floor appearance and coefficient of friction would be needed.
