Previous work has demonstrated the effectiveness of observational learning. A previous study on children with cerebral palsy Efficacy of a home-based platform for child-to-child interaction on hand motor function in unilateral cerebral palsy presented by Naura, Avanzini, Rizzolatti and Fabbri-Destro, showed that motor learning by observation is greater and presents more evident benefits when subjects learn from other patients with the same condition and less severity than when they learn by observing the therapist or another person without motor impairment. This work seeks to measure the improvements, both motor, functional and social, that patients with cognitive impairment can achieve with such an intervention.~This work is an experimental study based on the stimulation of mirror neurons. The planned sample size is 11 pairs in the experimental group and 11 pairs in the control group. Each group will be composed of eleven subjects with moderate cognitive impairment (MCI) and eleven with mild cognitive impairment (MCI), assessed by the minimental test. During the sessions, the MCI patient will observe his MCI partner and perform a programme of motor activities for the upper limb. At the same time the mild patient imitates the movement performed by the physiotherapist, all based on the AOT.~The activities will be based on items of the FUGL-MEYER scale. The sessions will last between 15 and 20 minutes and will be held three days a week. The intervention will last 5 weeks, with an initial assessment, 11 intervention sessions and a final assessment.~Inclusion criteria are: institutionalised patients over 65 years of age with mild cognitive impairment (minimental test between 19 and 23) or moderate cognitive impairment (minimental test 14-18); patients who perform physiotherapy exercises twice a week or attend occupational therapy twice a week; patients supervised by geriatric assistants or nurses during basic activities of daily living.~Exclusion criteria are considered to be: patients with musculoskeletal and neuro-musculoskeletal pathology of the dominant upper limb (outside MCI and MCI); presentation of visual deficit not correctable with glasses; patients with aggressive behavioural alterations or emotional lability; presentation of severe hypoacusis not correctable with hearing aids.~Data will be collected at the functional level, with respect to motor changes and also social modifications that have been perceived by the participants, carers and therapists.~The variables considered in this study are, as primary variables, motor changes, using the Fugl-Meyer scale, and perception with respect to social interaction; as well as mood. The latter two will be collected through interviews with patients, caregivers and therapists.~As secondary variables, functional changes in feeding (feeding time, errors in food intake, accuracy in bringing food to the mouth) will be considered. The impact on patient independence (Barthel index score) will also be considered. Finally, data will be analysed using SPSS statistical software. Non-parametric tests for related samples will be used in order to study changes in the variables collected before and after the intervention. The sample will be recruited from the old people's home Nuestra Señora de la Soledad in Parla, Madrid (collaboration agreement attached) depending on whether or not they meet the inclusion criteria.~Participants and/or legal representatives will sign an informed consent form once they have decided to participate after having received an information sheet with a detailed description of the study procedure and clarification of any doubts they may have (attached below). A consent form for the recording of patients during the assessments is also attached. The patient's personal data are coded in order to maintain their anonymity.~The handling and confidentiality of the data will be carried out in accordance with the regulations in force and following the Organic Law 3/2018, on the Protection of Personal Data and guarantee of digital rights.
