Background: Motor imagery is defined as the ability to mentally perform movement without movement execution. Although motor imagery has been used in many populations for a long time, its importance as a possible therapeutic tool for persons with multiple sclerosis (pwMS) has been recently understood. In order to add motor imagery into the rehabilitation programs, it is necessary to examine possible situations that may affect it. Since motor imagery processes play a crucial role in the experience of anxiety, it is also important to know the effects of anxiety on motor imagery abilities. Although there is relatively little evidence about how motor imagery is affected by anxiety in healthy people, to the best of our knowledge, this situation has been never examined in pwMS. The aim was to compare motor imagery abilities in pwMS with and without anxiety.
Methods: This cross-sectional study enrolled 27 pwMS. The participants were divided into two groups according to the cut off ≥ 8 on the Hospital Anxiety and Depression Rating Scale-A. Motor imagery ability was assessed using the Kinesthetic and Visual Imagery Questionnaire (KVIQ) and mental chronometry test for the Timed Up and Go (TUG) test. Temporal congruence between actual and imagined TUG was expressed as delta time calculated according to the formula: (actual TUG - imagined TUG)/[(actual TUG + imagined TUG)/2] x 100.
Results: There were 12 participants with anxiety and 15 without anxiety. Although the clarity of the image (KVIQ-Visual) and intensity of the sensations (KVIQ-Kinesthetic) were not significantly different between the groups (p>0.05), the participants with anxiety had less clarity of the image and intensity of the sensations with medium and small effect sizes (Cohen´s d=-0.62 and -0.39, respectively). No significant difference was observed in the delta time of TUG tests (p>0.05); however, the effect size was medium (Cohen´s d=-0.51).
Conclusions: Although the significance levels were not enough, the effect sizes have suggested that the pwMS with anxiety have less clarity of the image and intensity of the sensations, and temporal congruence between actual and imagined movements. These findings suggest that motor imagery ability can be affected by anxiety in pwMS and further studies with larger sample size were highly warranted.
