“…In the future, we will separate the auditory load from the visual load and include abstract as well as ecological sounds and perform the same number of repetitions on all scenes. Because previous studies did not find loudness/volume of the sound to be a factor in postural sway ( 6 , 54 – 57 ), we used the same volume with a range of 62 db (stars) to 68 db (city) for all participants. It is therefore possible that some participants, particularly in the hearing loss group, were not impacted by the addition of the sounds because the sounds were not loud enough for them.…”

“…Indeed, individuals with vestibular dysfunction complain of worsening dizziness and balance loss in complex settings such as busy streets (23)(24)(25). Data are accumulating regarding the importance of sounds for balance (6). Likewise, several studies suggested an independent relationship between hearing loss, balance impairments and increased risk for falls (26,27).…”

“…Likewise, several studies suggested an independent relationship between hearing loss, balance impairments and increased risk for falls (26,27). At present, the mechanism underlying imbalance in patients with hearing loss who do not present with vestibular symptoms is not clear; potential mechanisms include a common inner ear pathology, abnormal sensory weighting/reweighting, cognitive processing or a combination of these (6). Additional research is necessary to explore these and/or other mechanisms mediating imbalance in these groups.…”

“…Historically, the inputs considered for balance consisted of visual, vestibular, and somatosensory, but recent studies suggest that auditory input may serve as a 4th balance input ( 5 ). The presence of stationary white noise has been shown to be associated with reduced postural sway, particularly during challenging balance tasks such as standing on foam or closing the eyes ( 6 ). To understand the role of sounds in postural control, it is important to combine different levels of auditory and visual cues to better reflect day-to-day postural responses in healthy individuals.…”

“…Postural responses to visual perturbations and the contributions of sounds to balance are typically quantified via postural sway ( 6 ). HMDs, designed to move the virtual scene according to the participant's head movement, accurately ( 28 ) record head position at 60–90 Hz with no additional equipment ( 29 ).…”

Postural and Head Control Given Different Environmental Contexts

Virtual reality allows for testing of multisensory integration for balance using portable Head Mounted Displays (HMDs). HMDs provide head kinematics data while showing a moving scene when participants are not. Are HMDs useful to investigate postural control? We used an HMD to investigate postural sway and head kinematics changes in response to auditory and visual perturbations and whether this response varies by context. We tested 25 healthy adults, and a small sample of people with diverse monaural hearing (n = 7), or unilateral vestibular dysfunction (n = 7). Participants stood naturally on a stable force-plate and looked at 2 environments via the Oculus Rift (abstract “stars;” busy “street”) with 3 visual and auditory levels (static, “low,” “high”). We quantified medio-lateral (ML) and anterior-posterior (AP) postural sway path from the center-of-pressure data and ML, AP, pitch, yaw and roll head path from the headset. We found no difference between the different combinations of “low” and “high” visuals and sounds. We then combined all perturbations data into “dynamic” and compared it to the static level. The increase in path between “static” and “dynamic” was significantly larger in the city environment for: Postural sway ML, Head ML, AP, pitch and roll. The majority of the vestibular group moved more than controls, particularly around the head, when the scenes, especially the city, were dynamic. Several patients with monaural hearing performed similar to controls whereas others, particularly older participants, performed worse. In conclusion, responses to sensory perturbations are magnified around the head. Significant differences in performance between environments support the importance of context in sensory integration. Future studies should further investigate the sensitivity of head kinematics to diagnose vestibular disorders and the implications of aging with hearing loss to postural control. Balance assessment and rehabilitation should be conducted in different environmental contexts.

Cochlear Implantation in Meniere's Disease: A Systematic Review and Meta‐Analysis

et al. 2021

View full text Add to dashboard Cite

Objectives/Hypothesis: Meniere's disease (MD) is a debilitating condition characterized by hearing loss, vertigo, and tinnitus. The objective of this study was to systematically investigate outcomes in MD after cochlear implantation (CoI), with and without labyrinthectomy.Study Design: Systematic review and meta-analysis. Methods: A systematic review of articles in Medline and Embase was performed to identify all studies of patients with MD who underwent CoI. This analysis evaluates outcomes of speech recognition, pure tone audiometry, vertigo, tinnitus, and quality of life.Results: Of 321 studies identified, 37 were included, involving 216 patients. Mean age at implantation was 61.4 years (range 27-85 years) with average length of follow-up at 1.7 years (range 0-9 years). Forty-four (20.4%) patients underwent labyrinthectomy. Meta-analysis demonstrated significant improvements in audiometric outcomes following CoI. There was a statistically significant improvement in Hearing in Noise Test performance, with a mean difference improvement of 44.7 (95% confidence interval [CI] [8.8, 80.6]) at 6 months and 60.1 (95% CI [35.3, 85.0]) at 12 months. The Freiburger Monosyllabic Test (FMT) and Consonant-Nucleus-Consonant (CNC) also improved significantly, with mean difference improvements of 46.2 (95% CI [30.0, 62.4]) for FMT and 19.3 (95% CI [8.1, 30.4]) for CNC. There was a statistically significant decrease in tinnitus, as measured by a mean difference reduction of 48.1 (95% CI [1.0, 95.2]) in the Tinnitus Handicap Index.Conclusions: CoI with and without simultaneous labyrinthectomy is a viable treatment option for patients with MD, yielding high rates of tinnitus suppression and vertigo control. Post-CoI MD patients demonstrate similar postoperative speech perception outcomes to non-MD implant recipients.

The Effects of Vibratory and Acoustic Stimulations on Postural Control in Healthy People: A Systematic Review

et al. 2023

View full text Add to dashboard Cite

Research on human posture and balance control has grown in recent years, leading to continued advances in their understanding. The ability to maintain balance is attributed to the interplay of the visual, vestibular, and somatosensory systems, although an important role is also played by the auditory system. The lack or deficit in any of these systems leads to a reduced stability that may be counterbalanced by the integration of all the remaining sensory information. Auditory and vibratory stimulation have been found to be useful to enhance balance alongside daily activities either in healthy or pathological subjects; nevertheless, while widely investigated, the literature relating to these approaches is still fragmented. This review aims at addressing this by collecting, organising, and discussing all the literature to date on the effects of the various acoustic and vibratory stimulation techniques available on static upright posture in healthy subjects. In addition, this review intends to provide a solid and comprehensive starting point for all the researchers interested in these research areas. A systematic search of the literature was performed and a total of 33 articles (24 on vibratory stimulation and 9 on acoustic stimulation) were included in our analysis. For all articles, several elements were highlighted including: the study sample, the characteristics of the stimulations, the recording instruments, the experimental protocols, and outcomes. Overall, both stimulations analysed were found to have a positive effect on balance but more research is needed to align those alternative approaches to the traditional ones.
