Takimoto, T. Chikamori, H. Takebayashi, T. Okuda, S. Miyamoto, Y. Takuma, Y. Inoue, T. Okabe, K. Miyamoto Tosa Rehabilitation College, Department of Physical Therapy, Kochi, Japan Background: Perrochon et al. (2013) developed a novel secondary task using what they called a Walking Stroop Carpet (WSC), and they reported that mild cognitive impairment can be detected early, using this evaluation of gait ability. Purpose: We hypothesized that the WSC is effective to detect the people at risk of falling, and the present study was carried out to test this hypothesis. Methods: The participants were fifteen faller subjects (65–91 years) and fifteen non-faller subjects (70–85 years). The WSC was 1 m wide and 5 m long with ‘red’, ‘blue’, ‘yellow’ and ‘green’ written on targets arranged in four rows laterally and 10 rows lengthwise. The text on the targets was printed in various colors with none of the colors matching the name of the color written on any given target. The WSC tasks were done under three conditions. Under the text condition, the participants were instructed to step only on targets displaying a certain text. Under the color condition, the participants were instructed to step only on targets with text printed in a certain color. A WSC was also made with monochromatic signs for a black-and-white condition under which the participants were instructed to step only on targets displaying a certain text. Participants walked on the WSC once under each condition. For each trial, the required time was measured. In addition, 10 m walking trials and the Timed Up and Go Test (TUG) were administered. For statistical analysis, all the variables were subjected to unpaired Student’s t-tests for comparison between the groups. To investigate how well the WSC discriminated fallers from non-fallers, an evaluation was performed with ROC curves. The objective variable was the presence or absence of a fall history. The explanatory variables included time to the three WSC conditions and walking ability.
Results: The time to perform the WSC trials did significantly differ between the groups under the color condition (7.0 ± 2.5 s for fallers vs. 5.2 ± 1.3 s for non-fallers, p < 0.05). Other WSC trials did not significantly differ between the groups. In measuring the walking ability, 10 m walking time did not significantly differ between the groups. However, the TUG results significantly differed between fallers (10.8 ± 2.8 s) and non-fallers (8.1 ± 2.1 s, p < 0.01). With the three conditions of the WSC and the TUG used as explanatory variables in the ROC curve analysis, the color condition of the WSC was found to have the highest discrimination capability (AUC = 0.82, cutoff at 4.97 s, TPF = 86.7%, and FPF = 26.7%). Conclusion(s): The color condition of the WSC appears to be useful for evaluating the risk of falling, as the fallers were significantly slower than the non-fallers under this condition, and its capability to discriminate fallers from non-fallers was high. Implications: In a very elderly society, an evaluation method that more sensitively measures the risk of falling in elderly people living in communities is needed. In addition, the WSC may also be applicable in fall prevention training. Keywords: Walking Stroop Carpet; Falling; Elderly Funding acknowledgements: Our study did not need a fund.
