Summary
The Social Rhythm Metric (SRM) is reliable for stroke patients, showing less daily activity regularity correlates with greater physical compromise. This tool aids chronobiological studies in stroke recovery.
Area of Science:
- Chronobiology
- Neuroscience
- Rehabilitation Medicine
Background:
- Stroke significantly impacts physical and social functioning due to cerebral circulation abnormalities.
- The Social Rhythm Metric (SRM) measures daily activity regularity but has not been validated for stroke patients.
Purpose of the Study:
- To validate and translate the SRM into Portuguese for stroke patient assessment.
- To evaluate the daily activity regularity in stroke patients using the validated SRM.
Main Methods:
- Conceptual translation and validation of the SRM into Portuguese.
- Clinical evaluation and two-week SRM activity recording for healthy individuals and stroke patients (45-65 years).
- Statistical analysis using Pearson correlation and Fisher tests.
Main Results:
- The Portuguese SRM demonstrated reliability (r=0.84) and validity, with normative scores from 3.2 to 7.0.
- Stroke patients (mean SRM score 4.8) showed less activity regularity than healthy individuals, correlating with greater neurological compromise (r=-0.29).
- Stroke patients engaged in fewer work, leaving home, and social activities compared to controls.
Conclusions:
- The validated Portuguese SRM is a reliable instrument for chronobiological research in stroke patients.
- Reduced daily activity regularity in stroke survivors is linked to neurological deficits and decreased social engagement.
- Further longitudinal studies using the SRM are recommended to track stroke patient recovery and health status.
