The unique interaction between virtual reality and physical therapy in recovery of the adhesive capsule

Introduction.With the passage of time, medicine advances, as does technology.The latest medical innovations were through the creation of surgical robots that made possible surgical interventions that were dreamed of 10 years ago.At the same time, the physical therapy department also had to "suffer" through the development of feedback robots for gait recovery, robots for upper limb recovery and more.The pioneer in this directive is Virtual Reality (VR), which aims to move to an environment that is much easier to work with and control.Virtual reality is: "a way for humans to visualize, manipulate and interact with computers and extremely complex data" [Aukstakalnis & Blatner, 1992] (the way through which people can visualize, manipulate and interact with computers and complex data) more precisely it can be an advanced form of a human-computer, an interface that allows the user to interact in an environment generated by an almost real, natural computer, just like in airplane, train, car simulators in which pilots train for the development skills.The same environment can be created to develop and recover cognitive and functional abilities, bringing interactive scenarios designed to meet the needs of patients or create tasks similar to the real world.Adhesive capsulitis, also known as frozen shoulder, is a condition that causes a significant loss of both active and passive range of motion of the shoulder that occurs in the absence of preceding pathology.There are two types of frozen shoulder, primary and secondary.In the first type, patients have no findings on clinical examination, radiography or in their history that would explain the loss of range of motion.Primary frozen shoulder is the most common type and is idiopathic in nature.The Secondary Type develops after events such as upper extremity surgery or trauma.The limb is constantly unused and held in a position of internal rotation, shoulder adduction with elbow flexion.Consequently, the anteroinferior aspect of the joint approximates and shortens, resulting in a restriction of movement.Adhesive capsulitis recovery (frozen shoulder) causes limitation of movement in the shoulder joint through contraction and scarring of the joint capsule.the latest studies show that it affects approximately 2% of the world's population, especially people between 40 and 60 years old.Signs and symptoms usually start gradually, get worse over time, and then resolve, usually within one to three years.Your risk of developing frozen shoulder increases if you are recovering from a medical condition or procedure that prevents
