Shoulder Posterior Instability

The clinical investigation is designed as a controlled, two-arm, intra-patient, non-randomized interventional study aimed at assessing the capabilities of the AuReha system in detecting upper limb movement precision in patients with unilateral proprioceptive impairment. The comparison will be conducted within the same subject, between the healthy limb and the impaired limb, through the execution of proprioceptive exercises in an open kinetic chain. The biomechanical parameters collected will include movement precision, trunk stability, compensatory movements, and joint range of motion. In addition to the quantitative analysis, qualitative data will also be collected regarding usability, wearability, and user experience of the system through questionnaires administered to both patients and healthcare professionals. The study will be conducted at the Shoulder Team Outpatient Clinic in Forlì, enrolling approximately 52 patients.
