Data Accuracy, Reproducibility of Results, RehabilitationAbstract
Introduction: Graduated motor imaging has shown very promising results in the field of rehabilitation as a complement to other conventional treatment modalities. The potential benefit of techniques related to the mental representation of movements and activities is determined by the ability of the subject to evoke mental images. The Mental Evocation of Images, Movements and Activities Questionnaire (CEMIMA) was designed to evaluate the evocation capacity of the upper limbs specifically. Objective: To analyze the psychometric properties of CEMIMA in a sample of healthy adults. Method:In a sample of 75 subjects (53.3% women and 46.7% men), with a mean age of 40 years, internal consistency, intra-rater reliability (test-retest), and concurrent criterion validity of the instrument under study with the Movement Imagery Questionnaire-Revised (MIQ-R) were analyzed. Results: The CEMIMA showed good internal consistency both in the total scale (α = .82) and in their respective subscales of evocation (α = .89) and sensation (α = .83); adequate intra-rater reliability with high correlations between test and retest scores, both in the total scale (r = .84), as well as in the evocation (r = .91) and sensation (r = .92) subscales; and concurrent validity with MIQ-R (r = .63) and its corresponding subscales. Conclusion: The CEMIMA seems to be a valid and reliable measure of the mental evocation capacity of sensation and movement-image in healthy adult subjects.
