Different types of neurological deficits and sequels in the upper extremities that affect the activities of daily living in patients who have undergone stroke, have been analyzed from a subjective clinical point of view. Prognosis recovery after stroke depends on many factors, among which are included individualized program of rehabilitation and cooperation of patients. Simulation patients in the beginning of stroke. The aim of this work is to show a novel environment to simulate the initial improvement upper limb functions a few days after stroke and simulate the functional recovery of patients under a rehabilitation program. Twenty-nine patients in the first four days post stroke were selected. Inclusion criteria were: over eighteen years of age, collaborative patients, and neurological deficits in upper extremities post stroke without a previous history of stroke of motor sequelae second to other neurological or osteoarticular diseases that might identify pre-existing disability. Assessments were performed with 3-4 days and 7 days and 1, and 3 months post stroke recording the following variables: demographics, stroke type, stroke classification according to the Oxford scale, neurological deficit determined by the NIHSS, disability measures (Barthel’s Index, Rankin Scale), assessment of the motor dysfunction of the upper extremities according to the Fugl-Meyer Scale as well as muscle tone (Ashworth’s Scale) and muscle balance of the upper extremities. We measured the deficits of angles, lengths and range of motion for the arm and hand affected. These measures were implemented in a virtual environment with 29 DOF for each arm and hand. The different types of deficit and sequelae seen in the upper extremities of stroke patients impairing their activities of daily living have been analysed from a subjective clinical standpoint based on clinical and functional assessments. The prognosis for recovery of each patient very much depends on many factors, which can be found in the rehabilitation program and individual goals together with the collaboration afforded by the patients themselves while they are unaware a priori of the objective outcome of the rehabilitation process.
