Tags : Walk Eyes closed Romberg Goggles Balance Résumé : Background: The Romberg test, with the subject standing and with eyes closed, gives diagnostic arguments for a proprioceptive disorder. Closing the eyes is also used in balance rehabilitation as a main way to stimulate neural plasticity with proprioceptive, vestibular and even cerebellar disorders. Nevertheless, standing and walking with eyes closed or with eyes open in the dark are certainly 2 different tasks. We aimed to compare walking with eyes open, closed and wearing black or white goggles in healthy subjects.
Methods: A total of 50 healthy participants were randomly divided into 2 protocols and asked to walk on a 5-m pressure-sensitive mat, under 3 conditions: (1) eyes open (EO), eyes closed (EC) and eyes open with black goggles (BG) and (2) EO, EO with BG and with white goggles (WG). Gait was described by velocity (m·s−1), double support (% gait cycle), gait variability index (GVI/100) and exit from the mat (%). Analysis involved repeated measures Anova, Holm-Sidak's multiple comparisons test for parametric parameters (GVI) and Dunn's multiple comparisons test for non-parametric parameters.
Results: As compared with walking with EC, walking with BG produced lower median velocity, by 6% (EO 1.26; BG 1.01 vs EC 1.07m·s−1, P =0.0328), and lower mean GVI, by 8% (EO 91.8; BG 66.8 vs EC 72.24, P =0.009). Parameters did not differ between walking under the BG and WG conditions.
Conclusion: The goggle task increases the difficulty in walking with visual deprivation compared to the Romberg task, so the goggle task can be proposed to gradually increase the difficulty in walking with visual deprivation (from eyes closed to eyes open in black goggles).

Tags : Eyes closed Sensory alteration Sensory reweighting Sit-to-stand (STS) Unstable surface Résumé : Background: Postural stability during sit-to-stand (STS) movements depends on visual and somatosensory information. A modification of the 30-sec chair-stand test (30s-CST) with visual and somatosensory alteration (m30CST) may improve the ability to identify fall status.
Objective: This study aimed to investigate the accuracy of the m30CST in predicting falls in older adults.
Methods: This prospective cohort study recruited a convenience sample of 73 individuals from Kao Kilo community, Chonburi, Thailand. Eligibility criteria were age≥65 years and independent STS ability. All participants performed the 30s-CST and m30CSTs (i.e., eyes closed and a foam surface and eyes closed and a foam surface). The fall incidence during a 6-month follow-up was recorded. The area under the receiver operating characteristic curve (AUC) was calculated. Twenty participants were designated for reliability and validity analyses using the 30s-CST and the Fullerton Advanced Balance (FAB) Scale, estimating intraclass correlation coefficients (ICCs).
Results: We included 37 fallers and 36 non-fallers. All tests showed excellent accuracy in classifying fallers (AUC=0.770.91). The m30CST with eyes closed and a foam surface had the highest AUC (0.91), with a cutoff score of 9.25 repetitions, sensitivity 92%, and specificity 81%. The m30CSTs presented excellent inter-rater reliability (ICC=0.930.96) and testretest reliability (ICC=0.900.96), good to excellent correlation with the 30s-CST (r =0.900.98), and moderate to good correlation with the FAB Scale (r =0.640.73).
Conclusions: The m30CST could be used as an alternative evaluation for predicting the risk of falls in community-dwelling older adults, with excellent accuracy.
