Virtual embodiment reduces fear of movement after knee surgery

Virtual embodiment and virtual exercising are a promising adjunct to treatment for orthopedic patients, who face challenges from physical and psychological barriers during rehabilitation. This randomized controlled trial evaluated the impact of VR on post-surgical knee recovery. Patients (n=47) were assigned to either conventional rehabilitation or conventional plus daily 20-minute VR training, which utilized embodied avatars for movement visualization. The VR group demonstrated a substantial reduction in kinesiophobia scores at 4 weeks post-surgery (p=0.043). No significant differences were observed in quadriceps strength, knee range of motion, and disability scores. These findings support VR's potential for addressing psychological barriers in rehabilitation.
