Immersive Virtual Reality for Pain-related Movement Dysfunctions in Patients With Chronic Shoulder Pain

The goal of this clinical trial is to the use of VRi specified effects on pain, kinesiophobia, fear of pain, disability, self-efficacy, grip strength and range of motion in motion in people with chronic shoulder pain. The main question[s] it aims to answer are:Can specific immersive virtual reality software decrease movement-evoked pain in patients with chronic shoulder pain compared to non-specific software?Can specific immersive virtual reality software increase shoulder flexion range of motion in patients with chronic shoulder pain compared to non-specific software? Participants will use a specific VRi software compared with non-specific VRi software

Inclusion Criteria:People from 18 to 65 years oldShoulder pain of at least three months of evolution located in the proximal anterolateral region of the shoulderPresenting shoulder pain during movements with a history of traumatic or insidious onsetAgree to participate in the study and sign the informed consentExclusion Criteria:Shoulder pain resulting from cervical spine dysfunctionCognitive deficitsUso of medications for pain control in the previous 24 hoursA history of neurological or psychiatric disordersAdhesive capsulitis syndrome (limited passive range of motion of the shoulder: external rotation < 30°; elevation < 150°)Patients with shoulder instabilityPrevious surgery of the shoulder
