The International Association for the Study of Pain defines phantom limb pain (PLP) as that pain referred to a part of the body that has been previously removed as if it were still present. It affects between 55-80% of the population who has suffered an amputation, but not in the same frequency and intensity. Graded motor imagery (GMI) is a progressive, physiotherapeutic treatment modality developed to train and reorganize the brain based on three consecutive techniques: laterality recognition, motor imagery, and mirror therapy. The scientific evidence on the implementation of GMI in PLP is scarce, noting that there is no standardized way to use it in this patient profile. Therefore, the need is generated to develop and validate a GMI protocol to address the PLP and test its effectiveness. The study hypothesis is that graded motor imagery is a conservative treatment method based on motor learning, neuroplasticity, and mirror neuron stimulation that may have positive effects in decreasing phantom limb pain in the amputated patient, and as a consequence, decrease the associated psychological factors and improve the quality of life and functionality of the person. A randomized clinical trial will be performed with simple blinding, following the CONSORT guide for this type of study. It will be carried out at the community level with supervision and follow-up by the principal investigator.
