“…These responses were presumed as an anticipatory postural adjustment (APAs) mechanism to adapt unusual reception of visual input perturbation experienced by participants as the USN model. 5,16,20 Furthermore, our results confirmed that healthy subjects presented a small average across tests of bodyweight distribution. 27 2013), the bodyweight load ratio was not changed significantly in USN patients.…”

BACKGROUND: The present study developed a head-mounted display with the visual direction of a web camera modified to the right as a left unilateral spatial neglect (USN) model with respect to postural balance control. AIM: We aimed to estimate the validity and reliability of center of pressure (CoP) measurements in static standing balance (SSB) and dynamic standing balance (DSB) of healthy participants were using the USN model and to examine whether this model's use influenced postural balance control. METHOD: A portable CoP force plate was used to quantify postural balance control in 64 healthy participants as the model. The CoP displacement of the non-USN and USN models in the medial-lateral (ML) and anterior-posterior (AP) planes, CoP length, and bilateral load ratio in SSB and DSB to the right (R) and left (L) were evaluated. RESULTS: Regression analysis indicated that most CoP measurements have excellent concurrent validity. Bland–Altman plots showed good agreement between the non-USN and USN models in the CoP measurements. Test-retest reliability estimation between two times measurements varied in the frontal and sagittal planes. A Comparison of the results demonstrated that the CoP-AP and CoP length changed (-1.40% and 7.67%, respectively) significantly in SSB (P<0.05). Moreover, the CoP-AP changed very significantly in DSB-R and DSB-L (-1.50% and 1.86%, respectively) in opposite directions (P<0.01) when the subjects performed as the model. CONCLUSION: CoP measurements are valid and reliable to quantify standing balance control in both non-USN and USN models that appear to modulate changes in postural adaptation and adjustment.

“…18,19 Furthermore, the use of HMD with eyesopened affects an increase of the body sway during a standing posture. 20 In order to explore postural behavior in the USN condition, this study develops an HMD modification as the USN model with potential application in a clinical context. The model to replicate neglect experience is challenging.…”

“…Although discontinued by the manufacturer, it remains one of the most cost-effective apparatuses for measuring body sway. It is especially convenient when we do not need VR presentation, or when the weight of an HMD is not negligible in the balance of the body (see Imaizumi et al, 2020, on the effect of wearing an HMD; although the effect of weight was not very clear).…”

We compared two measures of visually induced body sway—head motion and centre of pressure (CoP)—that were simultaneously measured while observing optic flow on a head-mounted display (HMD). Head motion can be conveniently tracked with HMDs, but may have some features different from those of conventional CoP measurements, because of the complex joint structures of the human body. In this analysis, the responses were very similar (except for response gain), and we did not find any significant differences in time or frequency domains. Our results support the use of head motion as a potential predictor of variability in body sway, at least in studies of visually guided postural control.

“…As we know, former studies reported that actual USN patients were confused with MFV [20][21][22][23] . In comparison, the USN model condition with its HMD interferes and makes it difficult for the individual to process visual information that affected the postural balance [40][41][42][43][44] . Accordingly, the significant difference between the MVF and non-MVF subgroup only showed in some variables.…”

“…In addition, healthy participants have been involved in determining the physiological effects of the training developed [37][38][39] . Moreover, an increase of postural sway during the eye-opened quiet upright standing task was affected by wearing the HMD for virtual reality (VR) [40][41][42] . HMD modification as the USN model use procedure was explored in healthy participants.…”
