ABSTRACT
INTRODUCTION: Only a small number of clinical trials were designed to investigate Mental Practice (MP)'s use for gait rehabilitation in individuals in the early subacute post-stroke phase. This trial aims to investigate the effect of mental practice on mobility rehabilitation in the early subacute phase after a stroke in comparison to a control group. METHODS: Randomized controlled clinical trial with 16 individuals diagnosed with a stroke between 50 and 80 years of age. Mobility was evaluated using Timed Up and Go and the Five-Minute Walk Test. In addition, lower extremity muscular strength, Timed Up and Go Assessment of Biomechanical Strategies, quality of life, and depression were evaluated. RESULTS: Before and after intervention (within-subjects), mental practice group showed improved mobility in Timed Up and Go (p = 0.01,r = 0.59), muscular strength for bending the right hip (p = 0.04, r = 0.50), for right knee bending (p = 0.03,r = 0.53), and in biomechanical performance of Timed Up and Go Assessment of Biomechanical Strategies(p = 0.01,r = 0.63). Control group showed improvement in neither mobility nor in muscular strength after intervention. Comparing the scores between the groups after intervention (between-subjects), no differences were found for any of the study's outcomes. In the analysis of deltas (gains), it was observed that mental practice group volunteers had a reduction in Timed Up and Go (p = 0.27,r = 0.29) and an increase in total Timed Up and Go Assessment of Biomechanical Strategies scores (p = 0.14,r = 0.36). CONCLUSION: Mental Practice was not associated with mobility, muscular strength, mental health, and quality of life improvement for patients in the early subacute post-stroke phase as compared to a control group.
