Frozen shoulder is a common condition characterized by painful and limited range of motion. Using interactive technologies can help patients complete the exercises crucial to their rehabilitation. passive range of motion. The main treat-ment involves proper shoulder exercises and joint mobilization to break up adhesions at the joint capsules and improve joint mobil-ity and functions. However, due to a lack of persistence, not all patients complete rehabilitation. To address this, we created a virtual re-ality game-based treatment system that en-courages patients to participate in regular rehabilitation. Using our system, patients can inquire freely about their rehabilita-tion progress through real-time sensing and game-based feedback. Six progressive and hierarchical training tasks make each training step adjustable based on the pa-tient’s physical condition. To test our system, we used randomized clinical trial criterion to recruit 40 patients for a sequence of trials over a four-week period. Here, we describe our system and the study, as well as our re-sults, which show that patient shoulder joint mobility and muscle strength significantly improved for those using our system com-pared to those using the traditional rehabili-tation method. Frozen Shoulder Disease Frozen shoulder severity is categorized in four stages: preadhesive, adhesive, Frozen shoulder, or adhesive capsulitis, is a condition caused by impaired soft tissues and the articular capsule of the shoulder. It commonly occurs in people aged 40 to 65 years, and it’s more likely to appear in females than in males.1 Frozen shoulder is characterized by painful and limited active an
