Terapia en espejo y de observación de la acción en niños con parálisis cerebral espástica unilateral: estudio de viabilidad

INTRODUCTION. Unilateral spastic cerebral palsy affects upper extremity function. Mirror and home-based action observation therapies may be useful in its treatment. The aim has been to evaluate the feasibility of action observation therapy and mirror therapy programmes combined with home action observation in children with unilateral spastic cerebral palsy. SUBJECTS AND METHODS. The feasibility study included children (6-12 years old), randomly assigned to two groups: action observation therapy and mirror therapy and action observation. Twenty-hour home sessions were conducted, including unimanual and bimanual activities. Feasibility of interventions and procedures, and spontaneous use (Assisting Hand Assessment scale) and functionality (Jebsen Taylor Hand Function Test) of the upper extremity were assessed. RESULTS. Twenty-five families were recruited, with 17 meeting the inclusion criteria. Twelve children (8.75 ± 2.38 years) participated in the study. All families completed the interventions, with no adverse effects. The total intervention dose was above 96%. After the intervention, clinically relevant changes were found in both groups in spontaneous use of the upper extremity, as well as in functionality in the action observation therapy group. CONCLUSIONS. Action observation therapy and mirror therapy combined with action observation therapy are considered feasible to be applied at home and aimed at children with unilateral spastic cerebral palsy.
