Objective: This study assessed factors related to voluntary training undertaken by stroke patients. Methods: Patients who had been hospitalized for 1 or more months after stroke completed a questionnaire regarding their background, disease characteristics, voluntary training, outcome expectations, efficacy expectations, and the degree of life satisfaction. The Mann-Whitney U test, Fisher's exact test, and Spearman's rank correlation coefficient were used for analysis.Results: There was a significant positive correlation between the number of training days per week and the number of months after stroke. However, there was no significant correlation between the number of training days per week and outcome expectations, efficacy expectations, and the degree of life satisfaction. Conclusions:The factor related to the number of voluntary training days per week undertaken by stroke patients during the recovery phase was the number of months after stroke. In this period, outcome expectations, efficacy expectations, the degree of life satisfaction, and voluntary training by stroke patients may not be related. This may be because patients have mental agitation or a low degree of satisfaction during this period.
