Interventional
Description of intervention(s) / exposure
Both techinques, Constraint-Induced Moviment Therapy (CIMT) and Forced Use Therapy (FUT) use Immobilisation, mobilisation, and stretching of the non-paretic upper limb.
Immobilisation will be performed by means of a tubular mesh involving the non-paretic upper limb (UL) on abduction, rotating the shoulder internally, and allowing elbow flexion above 90 degrees. Immobilisation will be maintained for 24 hours during five days a week over a period of four weeks. The tubular mesh will be removed every day by the examiners for hygienisation, mobilisation, and muscle stretching of the UL with restriction. The non-paretic UL mobilisation will be performed by using traction techniques and joint circular movements, with 30 repetitions for each joint. All muscle groups of the UL will be submitted to stretching. A series of 3 repetitions consisted of keeping the extension pressure for 45 seconds will be performed. This procedure enabled the patient to have unrestricted movements for at least 60 minutes. Then, another immobilisation will be prepared using a new tubular mesh.
Only the patients in the CIMT group attended an exercise training program for 5 days a week during the whole experimental period. Each session will last 50 minutes on average. The program will follow a protocol consisting of kinesiotherapy and functional manual tasks for paretic UL. Each session will includ a 5-10-minute warm-up period, scapula mobilisation, flexion exercises and shoulder abduction, flexion exercises and elbow extension, flexion movements, trunk extension and rotation associated with upper limb movements, flexion exercises and wrist extension, and functional activities such as unlocking a door, typing a telephone number, turning on the tap, turning off the light, among other tasks.The protocol will be applied to paretic UL only, whereas the non-paretic UL will be under no restriction of movements. The exercises will be performed at maximum range, and whenever possible with some resistance by the physiotherapist. The sessions will be consisted of three series of 10 repetitions of each exercise. The rest interval between the exercises will be determined for each individual patient in order to avoid fatigue and excessive tiredness. In the both groups LL will be not stimulated.

Rehabilitation
Comparator / control treatment
The Forced Use Therapy will be the control treatment. As described above the immobilisation, mobilisation, and stretching of the non-paretic UL will be the same that CIMT. The only difference is the estimulation protocol.
Immobilisation will be performed by means of a tubular mesh involving the non-paretic UL on abduction, rotating the shoulder internally, and allowing elbow flexion above 90 degrees. Immobilisation will be maintained for 24 hours during five days a week over a period of four weeks. The tubular mesh will be removed every day by the examiners for hygienisation, mobilisation, and muscle stretching of the UL with restriction. The non-paretic UL mobilisation will be performed by using traction techniques and joint circular movements, with 30 repetitions for each joint. All muscle groups of the UL were submitted to stretching. A series of 3 repetitions consisted of keeping the extension pressure for 45 seconds were performed. This procedure will enable the patient to have unrestricted movements for at least 60 minutes. Then, another immobilisation will be prepared using a new tubular mesh.

Outcomes
Primary outcome [1] 259878 0
Lower limb function will be evaluated by using the Berg Balance Scale (BBS) and Fugl-Meyer Assessment of Motor Recovery (FMA).
The BBS assesses balance performance on 14 items. Each item has an ordinal scale of five alternatives ranging from 0 to 4 points. Therefore, the maximum score is 56 points.
The FMA evaluates the sensorimotor recovery of UL and LL post-stroke. The maximum scores are 66 and 34 points for upper and lower limbs, respectively, which defines a normal motor functio. In this case we only will use the 34 score.
Timepoint [1] 259878 0
Motor evaluation will be performed on a weekly basis during the 4-week experimental period and every 30 days after protocol for further three months. In this way, it will be carried out an initial evaluation (start), three weekly evaluations (1st, 2nd, and 3rd weeks), one final evaluation (4th week), and three follow-up evaluations (1st, 2nd, and 3rd months of follow-up).
Primary outcome [2] 266561 0
Gait analysis will be performed by using the 10-metre walk test (10mT) and Time-UP & Go test (TUG). The 10mT evaluates the time in seconds to walking a distance of 10 metres. The subjects will be instructed to conduct the test quickly and safely. In our work, the execution time of each evaluation test will be performed twice and this resulted in an average. TUG test measured (in seconds) the time the subject need to rise from a chair and walk a distance of 3 meters, return and sit down, without any assistance.
For both tests, the data of the start assessment will be normalized in percentage, corresponding to 100% of the time required to perform the test. Assessments of 1st, 2nd, and 3rd and 4th weeks, and 1st, 2nd, and 3rd months of follow-up, also will be normalized into the percentage, concerning the percentage of the start assessment.
Timepoint [2] 266561 0
Motor evaluation will be performed on a weekly basis during the 4-week experimental period and every 30 days after protocol for further three months. In this way, it will be carried out an initial evaluation (start), three weekly evaluations (1st, 2nd, and 3rd weeks), one final evaluation (4th week), and three follow-up evaluations (1st, 2nd, and 3rd months of follow-up).
Secondary outcome [1] 268754 0
The Stroke Impact Scale (SIS) version 3.037 will be used with the patients during their admission. SIS scale integrates significant dimensions of function and quality of life in a self-report. The version used has 59 questions and evaluates 8 domains (strength, hand function, performance and independence in activities of daily living, mobility, communication, emotion, memory and thought) with a maximum score of 295 points. In our study, we used only the items that assess the performance of activities of daily living, lower limb strength and locomotion (walking and transfers), resulting in a maximum score of 80 points.
Timepoint [1] 268754 0
This scale will be used during start and finish of the treatment (4th week), and in the follow up, 1st, 2nd, and 3rd months after the ending of the protocol.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
For randomization we wil use 40 sealed envelopes with the indication for an experimental treatment group. Each envelopes contains only one type of treatment. Each patient can freely choose a sealed envelope containing the assignment to an experimental group
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using 40 envelopes with one of these two therapies inside. There are 20 with constraint-induced movement therapy and 20 with forced use therapy. After sealed the envelope, they were shuffled and put in a box. In the moment that the patient accepts make part of this study, he os she can choose any envelope inside the box.
