The SUN.XR project focuses on rehabilitating women who have undergone mastectomy. In 2020, breast cancer affected 2.3 million women, with around 7.8 million worldwide living with a recent breast cancer diagnosis (WHO, July 17, 2023). The extensive surgery often leads to limited mobility, causing muscle atrophy, lymphatic issues, and pain. Additionally, breast cancer patients frequently battle fatigue due to chemotherapy and surgery. Here’s where XR technology plays a vital role by addressing motivation hurdles and providing personalized training resources.

Our hands and arms are essential for everyday tasks, and restricted upper limb function directly affects our quality of life. SUN.XR is at the forefront, developing innovative treatment, rehabilitation, and training methods that are yet to exist. XR is not merely for entertainment; its gamification aspect significantly boosts motivation through visual elements and rewards. Real-time feedback, enabled by high-sensitivity sensors, ensures precise tracking of training progress.Furthermore, XR facilitates remote treatments while maintaining a high level of monitoring for treatment success. Although XR development in this context is relatively new, initial studies already demonstrate its positive effects, especially concerning the upper limb system and enhancing the rehabilitation experience.
