Purpose: Motor imagery is considered as a complementary approach for functional recovery after stroke. Thus, applying reliable assessment tools to measure imagery ability in stroke is essential. The aims of this study were to apply Turkish versions of the Movement Imagery Questionnaire-3 (MIQ-3) and the Kinesthetic and Visual Imagery Questionnaire-20 (KVIQ-20) in individuals with stroke and investigate the validity and reliability of both questionnaires. Methods: Stroke patients with mild functional impairments (n=31) and healthy volunteers who age- and gender-matched were selected as a control group (n=29) were recruited to the study. The test-retest reliability was assessed using intra-class correlation coefficients (ICCs). Spearman’s correlation analysis was performed to assess concurrent validity of the KVIQ-20 with the MIQ-3. Furthermore, the internal consistency (Cronbach’s alpha) and factorial structures of both questionnaires were investigated. Results: Each sub-score of the MIQ-3 was found statistically different between stroke and control groups (p<0.001). Only visual sub-score of the KVIQ-20 yielded statistically different between stroke and control groups (p<0.001). ICC values were in the acceptable level of reliability (0.571-0.850). Both questionnaires had good internal consistency with high Cronbach’s alpha (Cronbach’s alpha test/retest for MIQ-3=0.941/0.970; test/retest=0.971/0.981 for KVIQ-20.). The concurrent validity between the KVIQ-20 and MIQ-3 was good (r=0.40, p<0.05). Exploratory factor analysis confirmed that MIQ-3 had three-factor and KVIQ-20 had two-factor structure. These obtained factors were explaining 88.99% and 80.87% of the total variance, respectively. Conclusion: Turkish versions of the MIQ-3 and KVIQ-20 are the tools with good reliability and validity to assess motor imagery ability in stroke patients with mild functional impairments.
