this study had as objective to correlate the resistance of the carotid artery and the functional autonomy of old women. the resistance of the carotid artery was evaluated through the method called doppler and the functional autonomy through tests related to daily activities (protocol gdlam). in the description of the data it was used measures of localization and dispersion. the internal right carotid resistance got mean and pattern deviation respectively (0,71 ± 0,07) and functional autonomy mean and pattern deviation respectively (30,40 ± 6,31). the coefficient of the correlation of spearman showed a strong association between the variation of the study (r = 0,998; p = 0,000). the results suggest that the bigger the table of contents of the resistance of the carotid artery is the bigger will be the difficulty of execution of the daily life tasks.
