Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Design: Randomized cross-over single-blinded trial. Subjects: Thirty-three patients post chronic stroke were recruited of the study.
Intervention: Patients who first participated in the MT intervention performed a single session of MT, whereas in the control intervention a single session composed of the same exercises was performed, but without the mirror. After a month washout, the patients switched groups.
Main measure: The primary outcome measure was motor control. The secondary outcome measure was manual dexterity and UE spasticity.
The data will be expressed as mean and 95% confidence interval (continuous variable) and absolute frequency (categorical variables). To compare the outcomes of the different experimental sessions and at the different moments (pre and post session), the Generalized Estimating Equations with post hoc LSD (Least Significant Difference) methods will be used. For all analysis the significance level was set at α = 0.05 and statistical software SPSS (Statistical Package for Social Sciences for Mac, version 22.0, IBM, USA) will be used.

Mirror Therapy Intervention
Mirror Therapy
The healthy UE will be positioned in front of the mirror and the paretic UE behind it, enabling the patient to observe the movements of the healthy limb through the mirror, interpreting that image as the affected limb. The MT protocol will be composed of active bimanual exercises of range of motion and functional exercises. Three sets of 15 repetitions will be performed for each exercise with a 20 seconds interval between each series, for 30 minutes. The exercises: 1) Elbow flexion/extension; 2) Wrist flexion/extension in neutral position; 3) Fingers flexion/extension in neutral position; 4) Forearm pronation/supination; 5) Roll the ball with hands; 6) Squeezing the sponge; 7) Drag a towel in anteroposterior direction; 8) Opponency of fingers; 9) Climb the mirror with the fingers (similar to walking the spider).
Control Intervention
Control Intervention
In the control intervention, patients will be performed the same bimanual activities proposed by the MT protocol, but without the reflector side of the mirror. The mirror will be placed in the same position as the MT intervention. However, the subject will have access to the non-reflective side of the mirror, directly visualizing the movement of his healthy arm.
Both interventions will be performed a single session of MT or control composed of 30 minutes of exercises. The participants who will be first assigned to the MT intervention, after 4-weeks washout period, will be performed the same procedures, but in the control intervention. Likewise, patients who will be first allocated to control intervention, after 4-weeks of washout, will be performed the same procedures, however in MT intervention.
