Clinical Study Of Digital Motor Assessment In Elderly Patients With Cerebral Small Vessel Disease

Objective:To analyze the performance of digital The Timed Up and Go test(dTUG)in elderly cerebral small vessel disease(CSVD)patients.Method:Forty nineCSVD patients admitted to our center from September 2021 to March 2022 were divided into severe CSVD group(n=13)and non-severe CSVD group(n=36)according to their Fazekas score with 11 age-and gender-matched persons who underwent physical examination in our center during the same period served as a conrol group.Demographiccharacteristics were recorded,Downtonfall risk index(DFRI)was used to evaluate fall risk,and traditional TUG was used.The parameters of dTUG were collected by NOKOV motion capture system(including phase 1 time,phase 1 swing amplitude,phase 2 time,phase 2 swing amplitude,phase 3 time,phase 4 time,phase 4 swing amplitude,phase 5 time).Results:There was no significant difference in gender,age and MMSE score among the three groups(P>0.05).The difference of DFRI scores among the three groups was statistically significant(P<0.01).The DFRI of patients with severe CSVD group was significantly higher than that of patients with the other group[3.00(3.00,6.00)vs 2.00(1.00,3.00)、2.00(0.00,4.00),P<0.05].Among the parameters of dTUG,the time of phase 3[(2.81±1.53)s vs(1.95±0.91)s、(2.13±0.61)s,P<0.05]and phase 4[(2.88±1.01)s vs(2.05±0.95)s、(2.35±0.65)s,P<0.05]were significantly prolonged,and the angular velocity of turn[(1.19±0.42)°/s vs(1.73±0.44)°/s、(1.51±0.41)°/s,P<0.05]was significantly slower.To analyze and compare the total time of TUG,the time of each phase,the swing amplitude of sitting-up and linear walking stage.Conclusion:dTUG found that the prolongation of time and slowing down of angular velocity in turn in phase 3 and the prolongation of time in phase 4 among elderly patients with CSVD,it reveals they have a higher risk of fall and potential motor disorders in their daily activities.
