“…It can be of various degrees that require hearing aids or cochlear implantation. It is known that auditory information plays a role in spatial representation and, to some extent, in postural stability, and this was shown in patients with hearing loss (21). In a recent study, Mazaheryazdi et al (22) explored postural function in 25 children (mean age: 9.3 years) with bilateral vestibular hypofunction deficit and unilateral or bilateral cochlear implants (CI) in two conditions: cochlear implant turned “on” and “off.” The authors observed that auditory information (with CI on) could improve postural stability and reduce body sways, suggesting that loss of hearing could lead to postural perturbations.…”

Postural Instability in Subjects With Usher Syndrome

This study investigated postural performances and vestibular impairment in Usher patients. The three groups studied were: 11 patients with Usher type I (with visual and vestibular impairment), 14 patients with Usher type II (with only visual impairment), and 14 healthy control subjects. Postural stability was measured with a Framiral Multitest Equilibre platform with three visual conditions: eyes open (EO), eyes closed (EC), and vision disturbed by optokinetic stimulation (OPT), and two different postural conditions: stable or unstable platform. The surface and mean velocity of the center of pressure displacement (CoP) were measured and a postural instability index (PII) was calculated. Usher type I and II patients were more unstable than control subjects, but only for the unstable platform. Patients with Usher type I (with severe vestibular impairment) were also significantly more unstable than patients with Usher type II (with normal vestibular function) on the unstable platform. The severity of the vestibular impairment was correlated with the surface of the CoP displacement. We suggest that poor postural control of Usher patients is due to the abnormalities in their visual and, when defective, vestibular inputs. Measurements of postural stability on an unstable platform can distinguish type I from type II Usher patients. We emphasize the importance of multisensory evaluation in these patients to guide development of personalized visuo-vestibular rehabilitation techniques to improve their postural stability and improve their quality of life.

“…Hearing loss has been associated with self-reported falls [Lin and Ferrucci, 2012] and reduced mobility [Viljanen et al, 2009a], linked, in part, to poorer postural control [Viljanen et al, 2009b]. Studies which have directly compared postural sway in hearingimpaired subjects and those with normal hearing have shown both poorer [Kluenter et al, 2009;Huang et al, 2011] and better [Walicka-Cuprys et al, 2014] postural stability in the hearing-impaired. When controlling for underlying vestibular deficits, which are often concomitant with hearing loss, no significant differences were found between subjects with normal hearing and hearing-impaired subjects [Suarez et al, 2007].…”

This study investigated the hypothesis that a hearing ‘map' of our surroundings is used to maintain balance control. We investigated the effects of sound on postural sway using centre of pressure analysis in 50 subjects with normal hearing, 28 with hearing loss and 19 with vestibular dysfunction. The acoustic environments utilized sound cues that were either present or absent. It was found that auditory cues are utilized by subjects with normal hearing to improve postural sway. The ability to utilize sound for postural control is diminished when there is a hearing loss, but this appears to be overcome by the use of a hearing aid. Patients with additional vestibular deficits exploit auditory cues to a greater degree, suggesting that sensory weighting to enhance the use of auditory cues may be applied when there is diminished sensory redundancy.

“…Accurate measurements of ground reaction forces from force plates are important in many areas of biomechanical research [5,8,9] . In the current study, force platform design and linearization algorithms have shown to be suitable to force and moment of force assessment (see Figure 6).…”

“…It should be designed and instrumented to obtain a bundle of signals, giving full information concerning the exerted force (including its COP). After a proper calibration [1,8] , this device could also be used in day-to-day biomechanical evaluation procedures as a force platform for static balance [8,9] or even for gait [10] and jump analysis [6] .…”

Force plates have been used in human movement analysis to measure ground reaction forces, centre of pressure (COP) and derived kinetic quantities. In competitive swimming external tridimensional (3D) forces assessment is crucial to improve starting technique performance. This work aimed to describe the design and construction of a 3D force plate prototype, which might be a modular sensor of an instrumented swimming starting block. For this purpose four steps were followed: 1) numerical determination of sensor conspicuous spatial positioning; 2) development of a first test device and respective calibration procedures; 3) final prototype (3D force plate) development and implementation; and 4) development and programming of a high speed multiple data acquisition system. Vertical force (< 140 N ± 5%) and COP real time determination (± 3% to centre distance uncertainty) are compliant with the literature data and horizontal force is assessed based on COP displacement time derivatives. The software for data acquisition and interpretation was developed, leading to calibration procedure that provides a set of gains for sequential balance protocol and final transfer matrix. Although the final prototype implementation was the main concern of the current study, its development also has proven to be an important milestone for a dynamometric swimming start block advance.
