Regularity of Daily Activities in Stroke

Various studies have been performed using the Social Rhythm Metric (SRM), though none has been developed with stroke patients. Stroke is a pathology that provokes a strong physical and social impact caused by an abnormality in cerebral circulation. Consequently, we performed two studies to validate the SRM and translate it into Portuguese, and to evaluate the regularity of the daily activities of stroke patients. Both healthy individuals and patients with unilateral cerebral lesions were evaluated. Subjects were of both sexes and between 45 and 65 yrs of age. Participants underwent clinical evaluation and recorded the time of 17 daily activities on the SRM for two weeks. Data were analyzed by the Pearson correlation and Fisher tests. After conceptual translation into Portuguese, corrections were made to arrive at the final version. Normative SRM scores varied from 3.2 to 7.0, suggesting that the activities presented in SRM adequately represented the daily routines of the patients. A correlation was found in SRM between the weeks (r=0.84; p=0.0001), indicating instrument reliability. The mean (±SD) score of the stoke patients was 4.8 (±1.0), and the correlation between the SRM and level of neurological damage showed that patients with lower SRM values were more physically compromised (r=?0.29; p=0.04), suggesting that SRM may be a clinical predictor. Activities related to eating and the sleep‐wake cycle were rated by most patients. In all, 71% of the patients did not work, while 84% of healthy individuals did (p=0.001). Only 64% of patients left home compared to 90% of the healthy subjects (p=0.001), and 59% of patients recorded the activity of going home compared to 82% of healthy individuals (p=0.001). According to the results, there is evidence of the validity and reliability of the SRM, enabling it to be reliably used in chronobiological studies of stroke patients. Given that a less regular lifestyle may be associated with neurological compromise and a decrease in social activities, we suggest new studies with the repeated application of this instrument over the clinical evolution of the disease to better define improvement or worsening of the patient's condition in terms of their social and health aspects.
