“…This study method is called the probe reaction time (P-RT) . Measuring phonatory reaction time is particularly recommended as in the above method it sensitively recognizes a slight change in attention demand in voluntary movement 9) . In this study, we report on a trial tool which is portable, easy to use and useful for the evaluation of the risk of falls, and discuss the relationship between the probe reaction time during rhythmic stabilization and subjects' risk of falls.…”

Abstract. [Purpose] This study examined the influence of the probe reaction time on sitting stability during rhythmic stabilization.[Subjects] The subjects were divided into two groups of thirty-three elderly subjects (70.0 ± 6.0 years), and ten younger subjects (22.4 ± 2.8 years).[Methods] We evaluated the simple reaction time, the probe reaction time during rhythmic stabilization, and the resistance force of rhythmic stabilization.[Results] The probe reaction time was significantly longer than the simple reaction time in both groups. The resistance force of rhythmic stabilization decreased in the Elderly group compared with the Younger group. Partial correlation analysis gave correlations of r = 0.87 for the probe reaction time, r = 0.87 for the simple reaction time, r = -0.34 for the probe reaction time and the resistance force, and r = 0.80 for the probe reaction time and the ΔRT (ΔRT= probe reaction time -simple reaction time).[Conclusion] The results suggest that not only the trunk muscle force but also the attention are factors influencing the sitting stability.

“…In movement-related research fields, the probe reaction time is used to estimate the attention demand required to perform the main task. Measuring phonatory reaction time is particularly recommended as a method to sensitively recognize a slight change in demand for attention during voluntary movement 12) . Another advantage of the probe reaction time is that it can be used for testing the heavily handicapped because the probe reaction time can be measured at subject's preferred exercise rate 13) .…”

Abstract. [Purpose] In this paper, we examined factors of physical function, reaction time and attention ability associated with falls.[Subjects] Twenty-seven young patients with post-stroke hemiplegia (males mean age 43.3±10.3 years), who had been receiving treatment at the China Rehabilitation Research Center, were divided into two groups: the Fall group and the No-fall group.[Methods] We evaluated the probe reaction time during walking, Trail Marking Test Part-A, Timed Up and Go Test, 10 m maximum walking speed, and the time of the walking cycle.[Results] The results show that the probe reaction time of the Fall group was slower, and the dispersion of the rhythm during walking was bigger than the No-fall group. In logistic regression analysis with fall as the dependent variable, the probe reaction time was identified as significant, and the cut-off value of the probe reaction time was 626 msec according to the ROC curve.[Conclusion] We consider that the probe reaction time is useful for the evaluation of falls risk in the patients with post-stroke hemiplegia.
