The aim of this study is to evaluate the effectivity of the combined motor imagery and action observation therapies to improve functional parameters such as strenght, range of motion, pain or fear of movements among others in relation to upper limb in breast cancer survivors. The main question it aims to answer is: Will a combined therapy of motor imagery and action observation improve the strenght, rang of motion, pain, limb diameter and fear of movement of the upper limb in breast cancer survivor females? The participants will be part of the IM-OA23 proyect that consist on seeing some diferent videos about upper limb mobility and then they'll have to imagine the movements and to performed themselves. Researches will compare two groups (control group and intervention group) to evaluate the diferences between them.
