Background:
While the development of motor imagery (MI) has been extensively studied in sighted children, it is not clear how children with different severities of visual impairment (VI) represent motor actions by using the motor representations constructed through the remaining intact senses, especially touch.
Aims:
Mental chronometry and generation/manipulation of MI were examined in children with and without VI.
Methods And Procedures:
Participants included 64 youth with and without VI (33 without visual impairments, 14 moderate-to-severe, and 17 blind). Mental chronometry was assessed with the imagined Timed-Up-and-Go-Test (iTUG), and generation/manipulation of MI with the Controllability-of-Motor-Imagery-Test (CMI). In addition, the effect of working memory performance (Letter-Number-Sequencing) and physical activity upon MI were evaluated.
Results:
Mental duration for the iTUG was significantly shorter than the active durations. Results also provided evidence of better haptic representation than motor representation in all participants; however, only for the CMI-regeneration condition controls outperformed children with visual impairments and blindness (CVIB). Exercise and working memory performance showed a significant contribution only on a few MI tests.
Conclusion And Implications:
Our results suggest a possible relationship between motor performance, body representation deficits and visual impairment which needs to be addressed in the evaluation and treatment of CVIB. The design of new rehabilitation interventions that focus on strengthening adequate body perception and representation should be proposed and tested to promote motor development in CVIB.
