Effect of combined rehabilitation and motor imagery on balance in the subacute stroke: a randomized controlled study.

INTERVENTION: An initial data collection will be carried out for each patient (posturography, Berg test; Barthel index; Time up and go test; ECVI‐38 quality of life questionnaire). For the posturographic analysis, the Satel PF8C posturograph will be used, three repetitions of the Romberg test with open eyes and stable surface will be performed for 60 seconds, from which the repetition data with the best score in the sweep area will be collected. The full version of the Berg test and the Time up and Go test will be administered to evaluate the postural control, static and dynamic balance of each subject, and the Barthel index to assess the level of activity of the subjects. In addition, ECVI‐38 questionnaire will be delivered for each participant to complete. This evaluation will be performed by the principal investigator. Once the initial data is obtained, all participants will undergo 5 rehabilitstion sessions per week of forty minutes each, in which their own neurological rehabilitation techniques will be applied in order to restore the patient's previous functional level. These techniques were carried out by professionals trained in neurorehabilitation with proven experience of at least 3 years. The sessions will be held for a period of 4 weeks until 20 sessions are completed. EG: The experimental group will hold 3 sessions per week of use of the Recognise® Flashcards on the recognition of the left / right laterality in images of feet in different positions added to rehabilitation sessions. 3 series of 20 different images will be presented in which the subject will identify whether it is a left or right member. A total of 12 sessions will be held with the help of a physiotherapist to perform laterality training; between each series a minute of rest will be l CONDITION: Physical Medicine / Rehabilitation ‐ Other physical medicine / rehabilitation Stroke ‐ Haemorrhagic Stroke ‐ Ischaemic stroke;rehabilitation; ; stroke ; rehabilitation PRIMARY OUTCOME: Changes in Berg Scale score[Baseline, at 4 weeks after intervention commencement] Changes in the sweep area (mm2) produced by the oscillation of the pressure center during the performance of the Romberg test with open eyes and stable surface, evaluated with the Satel PF8C posturograph.[Baseline, at four weeks after intervention commencement] Changes in Time up ang Go test[Baseline, at four weeks after intervention commencement] SECONDARY OUTCOME: Changes in Barthel Index[Baseline, at four weeks after intervention commencement] Changes in the percentage of load difference between both lower limbs, determined by the coordinates of the pressure center related to the average position when performing the Romberg test in Satel PF8C posturograph.[Baseline, at four weeks after intervention commencement] Changes inthe length of the oscillations (mm) produced by the subject during the 60‐second test of roomberg in Satel PF8C posturograph.[Baseline, at four weeks after intervention commencement] quality of life assessed using the ECVI‐38 Quality of Life Questionnaire[Baseline, at at 4 weeks after intervention commencement] INCLUSION CRITERIA: 1) first stroke within the previous year; 2) over 18 years; 3) ability to maintain steady standing for 1 minute without supports; 4) sensorimotor disturbance that occurs with hemiparesis secondary to the stroke and alteration of the gait pattern.
