Summary
Stroke survivors spend over 80% of their day sedentary, with no change in behavior over a year. Reducing sedentary time may be a key rehabilitation target for these patients.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Physical Therapy
Background:
- Stroke survivors often exhibit prolonged sedentary behavior, impacting recovery.
- Understanding the patterns and changes in sedentary time post-stroke is crucial for effective rehabilitation strategies.
Purpose of the Study:
- To quantify longitudinal changes in sedentary behavior after stroke.
- To determine if reducing sedentary behavior could be a novel therapeutic target in stroke recovery.
Main Methods:
- A longitudinal cohort study followed 96 acute stroke patients for 1 year.
- Objective measures assessed total sedentary time, bout length, and fragmentation.
- Data were analyzed using linear mixed effects models, controlling for covariates.
Main Results:
- Stroke survivors spent a median of 19-20 hours daily in sedentary behavior (81% of the day).
- Sedentary behavior patterns remained consistent throughout the first year post-stroke.
- Higher stroke severity and lower functional independence were associated with increased sedentary time.
Conclusions:
- Stroke survivors exhibit persistently high levels of sedentary behavior one year post-stroke.
- Sedentary behavior levels were independent of functional ability.
- Interventions targeting sedentary behavior reduction show promise as a new therapeutic avenue in stroke rehabilitation.
