Recovery time of independent poststroke abilities: Part I.
The purposes of this study were to determine the time of the recovery of poststroke abilities and to identify prognostic indicators associated with recovery time among stroke patients undergoing a rehabilitation program. A sample of 421 stroke participants admitted to a rehabilitation center was recruited from medical records that were available from January 1987 to December 1992. The mean age was 61.8 years (range, 17-89 years). The relationship between the achievement of independent poststroke abilities and the potential covariates associated with recovery time was assessed through the analysis of survival data. Cox maximum-likelihood proportional hazard models were used for the analysis. Independent poststroke abilities included behavior, cognitive, perceptual, communication, visual, and motor status. The time from rehabilitation admission to complete independence was introduced to the model in relation to the covariates. The mean time of recovery of poststroke abilities ranged from 18.70 to 32.40 days from the rehabilitation admission. The survival analysis revealed that the time of recovery of the selected poststroke abilities was significantly influenced (p <.05) by one or several factors, among these were neuropsychological, physical, and life habits. With this precious information, stroke rehabilitation specialists may be able to reduce the length of time required to recover independent poststroke abilities by treating the specific neuropsychological, physical, and life habit characteristics identified in this study. A faster poststroke recovery will reduce the socioeconomic impact generated by stroke disability and will ensure a better quality of life to the stroke survivor.
