Overview
Brief Summary
Stroke is a neurovascular event characterized by impaired blood supply to the brain due to rupture or obstruction of certain cerebral arteries, which often results in hemiparesis and can affect individuals of any age and sex, being prevalent in the elderly population.
Among the main treatments available for stroke rehabilitation, most of them demands an appropriate structure and high-qualified personnel. Searching for more affordable treatment options, several studies suggest the use of mental practice with motor imagery as a potential therapeutic tool, since it can be performed at any place or any time the patient wishes, including their own homes.
Motor imagery can be defined as the covert cognitive process of imagining a movement of your own body(-part) without actually moving that body(-part).
Within this context, the objective of this study is to investigate the effects of mental practice for mobility, gait function and speed and muscle strength of the lower limb in subacute post-stroke hemiparesis.
Detailed Description
Post-stroke patients will be invited to participate after hospital discharge, based on inclusion and exclusion criteria. Then, after acceptance, participants will be randomized (block strategy) into two groups: Control group (Physiotherapy and Cognitive mental exercise) and Intervention group (Physiotherapy and Mental Practice group). At baseline, 4 weeks (end of intervention) and 6 weeks, participants will be evaluated through the following tests: Timed-Up and Go test, 5-Meter Walk Test, TUG-ABS, WHOQOL-Bref, DASS-21 and muscle strength.

- •only one cerebral hemisphere affected;
- •no chemical, alcohol or drug dependency;
- •Score average ≥ 2,5 point in the instrument "Visual and Kinesthetic Imagery Questionnaire" (KIVQ-10);
- •No cognitive impairment (18 points in the Mini-Mental State Examination - 0-4 years of educations and 24 points (\>4 years of education);
- •Not participating in any other type of physiotherapy or physical activity during the study period;
- •Complaining of difficulty in gait and mobility after stroke;
- •Able to stand up from a chair and walk some distance with or without auxiliary device;
Exclusion Criteria
- •Hemorrhagic or ischemic progressing to hemorrhagic stroke;
- •Score ≥ 4 on the Visual Analogue Pain Scale;
- •Score ≥ 2 on the modificator Ashworth scale;
- •Visual disabilities;
- •Severe Aphasia;
- •Cardiovascular instability and/or other neurological disorders that may impair the mobility and gait.
Outcomes
Primary Outcomes
Change in Timed Up and Go (TUG)
Time Frame: 1 week before intervention; 4 weeks after intervention; 6 weeks after intervention
This is a measure that examines the participant's basic mobility skills by measuring seconds to rise from sitting, walk 3 meters, return, and sitting down
5-Meter Walk Test
Time Frame: 1 week before intervention; 4 weeks after intervention; 6 weeks after intervention
This is a measure that examines the participant's gait speed (cut off 6 seconds)
Secondary Outcomes
- Change in Quality of life(1 week before intervention; 4 weeks after intervention; 6 weeks after intervention)
- Change in Muscle strength(1 week before intervention; 4 weeks after intervention; 6 weeks after intervention)
- Change in Mental health(1 week before intervention; 4 weeks after intervention; 6 weeks after intervention)
- Change in TUG-ABS(1 week before intervention; 4 weeks after intervention; 6 weeks after intervention)
