Context: Virtual reality environments may allow researchers to investigate functional balance performance without risks associated with testing in the real world.
Objective: To investigate the effects of the mass of a head-mounted display (HMD) on balance performance.
Design: Counterbalanced pretest-posttest.
Setting: Virtual reality laboratory.
Participants: 20 healthy college students.
Intervention(s): Balance Error Scoring System (BESS) with a tracker-only headband and again with tracker plus HMD was performed.
Main outcome measures: BESS error scores, elliptical sway area, and center of pressure travel distance were recorded.
Results: No effect of the HMD mass on balance performance was observed. A significant stance by surface interaction was present but was negated when the HMD conditions were included in the model.
Conclusions: The mass of a HMD has not been proven to adversely affect balance performance. These data suggest the HMD mass is not a contraindication to the use of immersive virtual environments in future concussion research involving balance.
