Stroke: After a stroke, how does the patient's long-term life function change?

Among post-stroke survivors, it is estimated that more than 20% are restricted in daily life (ADL), and more than 30% are restricted in instrumental ADL (IADL), and these percentages are affected by stroke It has been increasing in the years after the incident

This makes stroke the main cause of long-term disability in the United States and one of the most common causes of disability in the World Health Organization in Europe, especially among the aging population, and the burden of stroke is expected to increase in the next few decades

In the acute phase after a stroke , the limits of ADL and IADL differ greatly.

Although there is a large amount of literature on activity limitations in the subacute phase, few studies have studied the chronic phase

Research on chronic phase after stroke often ADL and IADL scale into two (yes / no limit), suddenly a little of the ADL and IADL limit the number of changes and the severity of restrictions at the beginning into the chronic phase, it may be Predictors of prognosis

(1) Assess the difference in the IADL and ADL limits of the respondent with no stroke and after the stroke in different age groups over time, and evaluate the difference in age effect;

(2) Using 20-year data from three large-scale cohort studies conducted in Europe and the United States, assess the impact of the severity of disability at the beginning of the chronic phase after stroke on ADL and IADL restrictions

Data comes from the Health and Retirement Study, the European Health, Aging and Retirement Survey, and the Longitudinal Study on Aging in the UK.

3718 stroke cases were classified according to the degree of disability using the modified Rankin scale scores 1 to 2 years after stroke

The model was stratified by age group (50-74 years old and ≥75 years old), and adjusted for baseline characteristics, healthy behavior, BMI, and comorbidities

They found that within 3 to 6 years after the stroke, the ADL/IADL restriction was relatively stable, followed by an increase in both populations, and younger stroke cases increased more quickly, indicating a different age effect (P<0.

The important significance of this study lies in the discovery: in the chronic stage after stroke, functional limitation first stabilizes and then increases, and its evolution varies with the severity of the disability
