“…We have shown that there are significant differences between the stabilometric profiles of OSAS patients and controls. These results are coherent with previously published studies which have provided evidence that OSAS patients have poorer balance compared with a control population (12,13). Additionally, we have now shown that this increase in CP displacement amplitude specifically concerns the ML axis.…”

“…In particular, its association with intermittent hypoxia and altered sleep quality, the principal factors that lead to co-morbidity, remains purely theoretical. Indeed, though changes in stabilometric parameters have been correlated with sleep deprivation (17) or to profound hypoxia (18), which is not typically observed in studies of OSAS patients (12,13). Additionally, the intermittent hypoxia and altered sleep quality do not explain the hyperextension of the cervical spine and the forward projection of the head (9)(10)(11).…”

“…Recently, a specific postural dysfunction has been reported to be a feature of OSAS. Reported series describe abnormal spinal curvature, with cervical hyperextension and anterior projection of the head (9)(10)(11), disturbances of balance (12,13), and walking (12,14,15), and an increased risk of falls (16). These difficulties with balance and walking improve significantly after treatment with CPAP is instituted, suggesting that they are specifically related to OSAS (12,14).…”

“…The lack of this kind of association could be conditioned by diverse aspects, such as the subjective assessment of ESS and DHI (which can be influenced by different factors, i.e. depression) and the poor ESS correlation observed in the literature with objectively measured sleepiness (Chervin and Aldrich, ; Degache et al ., ). Conversely, a positive correlation between gain and mean SaO 2 and a negative correlation between CEYL and mean SaO 2 were found (Fig.…”

Vestibular dysfunction was linked to moderate-to-severe obstructive sleep apnea syndrome (OSAS) patients in literature. However, due to a lack of knowledge among valid and recent implementations conceived to study postural control on static posturography (SP) and vestibulo-ocular reflex (VOR) gain under physiological conditions (video Head Impulse Test; vHIT), the aim of this work was to integrate (i) VOR changes via vHIT implementation, (ii) postural arrangement by studying both classical parameters and frequency spectra (PS) and (iii) correlation between these findings, polygraphic (PG) and subjective scores along Dizziness Handicap Inventory (DHI) and Epworth Sleepiness Scale (ESS). Thus, 32 moderate-to-severe OSAS patients and 32 healthy subjects - studied by using PG, DHI and ESS - underwent vHIT and SP posturographic assessment. Analysis of variance was performed to disclose between-group effects and correlation analysis was implemented between otoneurological, PG, DHI and ESS values. OSAS group demonstrated a significant decay of VOR gain and an increase in both frequency spectra PS values, especially within the low-frequency interval, and in classical posturographic SP parameters. Further, positive and negative correlations between mean SaO and gain and low frequency interval spectra PS were found, respectively. Strengthening previous hypothesis related to brainstem chronic hypoxemia phenomena affecting vestibular network, implementation of these data could generate future attentions (i) for screening under physiological conditions postural and vestibular detriments in OSAS subjects, especially exposed at risk settings, and (ii) among PG parameters, such as mean SaO , to propose further reliable tools in monitoring postural and vestibular decay in these patients demonstrating PG parameters detriments.

“…There is also emerging evidence that OSA disturbs balance and gait, potentially increasing the propensity for falls, particularly in older patients. [35][36][37] Falls are a leading cause of injury, disability, and mortality worldwide 38 ; and therefore, OSA therapy may be a potential target to reduce falls risk. Preliminary evidence suggests that OSA therapy may reduce gait instability in OSA.…”

Obstructive sleep apnoea (OSA) is a common sleep disorder. Early population studies suggested that up to 10% of the middle-aged population 1-4 were affected, with as many as 80% of cases undiagnosed. 5-7 More recent estimates suggest that there has been a rapid rise in OSA prevalence with more than 20% of middle-aged individuals exhibiting moderate to severe OSA likely driven by increased global obesity as well as more sensitive OSA measurement techniques. 8,9 The main features of OSA are snoring and repetitive hypopnoea (reduced airflow) and/or complete collapse (apnoea) of the pharyngeal airway during sleep with associated transient oxygen desaturation (hypoxaemia), carbon dioxide retention (hypercapnia), and repeated arousal from sleep. The major risks factors for OSA are male sex, older age, and obesity. Daytime consequences of OSA Excessive daytime sleepiness. One of the main clinical symptoms of OSA is excessive daytime sleepiness (EDS). Those with EDS experience an increased propensity or 'pressure' to
