The aim of this study was to investigate the validity and reliability of the Kinesthetic and Visual Imagery Questionnaire (KVIQ) in acute stroke patients and to examine the relationship between functional level and motor imagery ability. The study was carried out in two stages. In the first stage, the reliability of the KVIQ and its convergent validity were investigated with comparator measures (mental chronometry (MC), Barthel Index (BI), Trail Making Test (TMT), trunk verticality, Motor Assessment Scale (MAS). In the second stage, the relationship between the functional levels of individuals and their imagination abilities was examined. Fifty acute stroke patients aged 50-75 years (mean±standard deviation=62.34±8.74) were included in the study. Test-retest reliability, internal consistency, and construct validity of the KVIQ in acute stroke patients were investigated. The test session was performed on the 3rd post-stroke day for each individual, and the retest session was performed on 31 individuals on the 7th post-stroke day. It was found that the questionnaire had good test-retest reliability for the visual subscale, moderate for the kinesthetic subscale, and good for the overall (intraclass correlation coefficient values: 0.88; 0.62; 0.84, respectively). The visual subscale, the kinesthetic subscale, and the overall questionnaire were found to have excellent internal consistency (Cronbach's alpha values: 0.961; 0.905; 0.953, respectively). Convergent validity of KVIQ was supported by its significant association with MC ratio (rho=-0.3, p=0.008), BI (rho=0.37, p=0.008), TMT (rho=-0.30, p=0.03), MAS (rho=0.31, p=0.04) The KVIQ had low-moderate correlation with these measuring tools. Trunk verticality was found to be associated only with the visual subscale of the questionnaire (rho=0.30, p=0.03). In the second stage, the relationship between functional level and motor imagery ability was examined, a low-to-moderate relationship was found between MAS and KVIQ, which evaluates the vividness of imagery (rho=0.31, p=0.04). No correlation was found between MAS and MC ratio (rho=0.02, p=0.88), which evaluates the temporal dimension of imagery. In conclusion, KVIQ is a reliable and valid measurement tool to evaluate motor imagery ability in acute stroke patients. In addition, there was a relationship between functional level and the viability of motor imagery in acute stroke patients, but no relationship was found between the temporal dimension. Different dimensions of motor imagery should be evaluated in studies.
