- Stroke is the most common life threatening neurological disorder in the U.S., affecting roughly 550,000 people each year. This secondary analysis of a dataset generated by Whitney and colleagues sought to describe individual trajectories of recovery following stroke, and identify variables associated with functional decline and recovery over twelve months. Stroke survivors (N = 173) were surveyed at the time of their strokes, and three, six and twelve months later on neurological and cognitive status, depression status, and functional ability. Demographic data (age, gender, marital status, laterality of lesion) was also considered in this analysis.
Graphical analysis of individual trajectories indicated that recovery was highly variable. Following a nearly universal increase in functional status over the first three months, many subjects experienced varying degrees of functional decline. Unadjusted and pairwise analyses of each of the independent variables compared to functional decline revealed a significant association between the outcomes of those who developed depression during recovery as compared to (a) those who never became depressed (p = 0.0048), and (b) those whose depression had resolved (p = 0.028). An effort to develop an association model for patients who declined functionally using logistic regression analysis removed all independent variables, including age. The same analysis performed to examine full functional recovery yielded a model that showed neurological status and functional status scores at three months post stroke were highly associated with full recovery ($-$2 log L-126.080; c = 0.864).
Trajectory analysis is a novel way of describing changes over time and the influence of covariates in a chronically ill population. Identifying influences that optimize functional recovery following stroke should continue to be a priority for researchers. Continued study using qualitative methods may provide stroke researchers with a better understanding of this process.
