Background and Purpose. Traditionally, rehabilitation programs emphasize training balance under single-task conditions to improve balance and reduce risk for falls. The purpose of this case report is to describe 3 balance training approaches in older adults with impaired balance. Case Descriptions. Three patients were randomly assigned to 1 of 3 interventions: (1) single-task balance training, (2) dual-task training under a fixed-priority instructional set, and (3) dual-task training under a variable-priority instructional set. Outcomes. The patients who received balance training under dual-task conditions showed dual-task training benefits; these training benefits were maintained for 3 months. The patient who received variable-priority training showed improvement on novel dual tasks. Discussion. Older adults may be able to improve their balance under dual-task conditions only following specific types of balance training. This case report gives insight on how this intervention might be combined with more traditional physical therapy intervention. [Silsupadol P, Siu KC, Shumway-Cook A, Woollacott MH.

As virtual and augmented reality simulation technologies advance, the use of such technologies in medicine is widespread. The advanced virtual and augmented systems coupled with a complex interactive, immersive environment create a metaverse. The metaverse enables us to connect with others in a virtual world free of spatial restrictions and time constraints. In the educational aspect, it allows collaboration among peers and educators in an immersive 3D environment that can imitate the actual classroom setting with learning tools. Metaverse technology enables visualization of virtual 3D structures, facilitates collaboration and small group activities, improves mentor–mentee interactions, provides opportunities for self-directed learning experiences, and helps develop teamwork skills. The metaverse will be adapted rapidly in healthcare, boost digitalization, and grow in use in surgical procedures and medical education. The potential advantages of using the metaverse in diagnosing and treating patients are tremendous. This perspective paper provides the current state of technology in the medical field and proposes potential research directions to harness the benefits of the metaverse in medical education, research, and patient care. It aims to spark interest and discussion in the application of metaverse technology in healthcare and inspire further research in this area.
