Introduction Vestibular otolith function plays a major role in balance control. Objective To investigate the saccular and balance functions of children with Down syndrome (DS). Methods In total, 15 children with DS aged between 9 and 11 years were included. An age- and gender-matched control group (CG) composed of 15 normal participants was also included. The subjects with DS had trisomy 21, without hearing or organic problems, and they had independence in stance. The saccular function among the children with DS and among the controls was tested using air-conduction cervical vestibular-evoked myogenic potentials (cVEMPs). In addition, the static and dynamic balance statuses were evaluated using the following assessments; the Pediatric Balance Scale (PBS), the modified Clinical Test of Sensory Interaction on Balance (mCTSIB), the Romberg test, and the Timed Up and Go (TUG) test. Results In the present study, the results of the saccular function test showed that there was a significant difference between children with and without DS (p < 0.05). The DS subjects had significantly earlier N1 latancy and lower amplitude of the cVEMPs (< 70 μV) compared with the control subjects. The static-dynamic balance ability was statistically and significantly different in children with DS compared with the controls (p < 0.05). Conclusion These results revealed that saccular function seems to be affected in DS subjects. The dysfunction in static and dynamic balance abilities of the children with DS may be attributed to vestibular dysfunction as well as low gross motor skills. This knowledge should be taken into account when assessing motor performance in those subjects. Additional larger studies testing other dimensions of the vestibular system in children with DS are needed.
Objective: This study was conducted with elderly individuals who had recovered from COVID-19 to investigate the effects of COVID-19 on balance, perception, attention, memory, and quality of life and produce rehabilitative solutions for these problems. Material and Method: A total of 45 volunteers older than 65 years who had not had COVID-19 were included in group 1. A total of 45 volunteers older than 65 years who had recovered from COVID-19 were included in group 2 (elderly people who have had COVID-19 at least 6 months ago). After obtaining the individuals' demographic data, we conducted vestibular assessment for balance and administered the Stroop test for attention, the Mini-Mental State Examination (MMSE), the digit span test for short-term memory, and a quality-of-life test. Results: Mean age of the individuals who had had COVID-19 was 68.24 ± 3.32 years, and the mean age of the individuals who had not had COVID-19 was 68.55 ± 3.34 years. There were statistically significant correlations between the two groups for the Stroop test (P < .05), MMSE (P < .05), the digit span test for perception and attention (P < .05), and the vestibular assessment quality-of-life test (P < .01). Sensory (P < .001), past, present, and future activities (P < .05), social participation (P < .001), and death (P < .05) were found to be significant in the total score (P < .001). The covariance analysis of elderly individuals who had had COVID-19 revealed that they performed significantly worse on the balance, perception, attention, memory, and quality-of-life tests than elderly individuals who had not had COVID-19. Conclusion: The negative effects of COVID-19 were found among elderly individuals older than 65 years. We suggest that telerehabilitation should be developed for elderly people who have recovered from COVID-19 and that its effects investigated.
