RESUMO:

Objective: To investigate the deterioration of gait in different conditions associated with cognitive planning in healthy elderly. METHODS: This was a cross-sectional study involving 17 elderly women aged 60-75 years (66.00 ± 4.67). Individuals were clinically described by means of the following instruments: Dynamic Gait Index, Berg Balance Scale, Mine Mental State Examination and Leganes Cognitive Test. The experimental protocol consisted of performing the three cognitive tasks of the Stroop test - Word (Pal), Color (Co) and Word-Color (Pal-Co) - in four gait conditions: treadmill running, disturbances (MS), ground running with straight disturbances (MSPR), and ground running at eight (MS8). Each task was performed three times, with duration of 20 seconds and intervals of three minutes. The ICM was evaluated by muscle contraction index (ICCm), number of steps (NP), cadence (Ca) and velocity (VL). The ICCm was collected by means of surface electrodes and an 8-channel electromyograph, along with pressure sensors on the treadmill for ME, and sensors fixed in walking soles that synchronized gait cycles (support and oscillation). The normality of the data was analyzed and the one-way ANOVA and Pearson's correlation using SPSS 2.0 software were used. Results: The cognitive tasks of the Stroop test presented a deterioration in the final score of the test, presenting a significant effect of the reduction of number of Words and number of Colors (p <0.05) in all conditions when compared to ME (Pal 33 , 78 ± 6.31, Co 23.19 ± 5.78) on MS (Pal 26.76 ± 6.59, Co 16.84 ± 5.55), MS 8 (Pal 25.72 ± 6.53; 15,17 ± 5,76) and MSPR (Pal 22,94 ± 7,22, Co 16,11 ± 6,00), whereas for Color Word there was a significant effect on the reduction in the number of items (p <0, 05) only when compared to ME (13.58 ± 3.16) with MSPR (9.88 ± 3.50) and MS8 (9.84 ± 3.50). When comparing the cost of the Stroop task in the steps and cadence of the different gait conditions, a significant change in gait variability was observed from the usual to the slower (p <0.05), however only MS x MSPR and MSPR x MS8 did not show these differences (p> 0.05), whereas the cadence was not significant in ME x Normal, MS x MSPR, MS8 x MS and MSPR (p> 0.05) situations. The correlation analysis revealed a significant and positive relationship between steps and cadence with the Stroop task, only in the MS8 situation with number of colors (r = 0.549, p = 0.022, r = 0.561, p = 0.019). Conclusion: The findings suggest that the cognitive task during gait variability was altered, suffering a negative impact as the load was increased, and that patterns of gait variability produced different measures in the steps and cadence being larger viewed only between the activities.
