“…Subsensory mechanical noise chips on the bottom of the feet reduce sway in clinical and typical populations (Priplata et al 2002(Priplata et al , 2003(Priplata et al , 2006. The explanation for this could be that noise increases somatosensory feedback from the feet.…”

“…The support for this is that mechanical noise can reduce sway both in people with peripheral and central deficits (Priplata et al 2003(Priplata et al , 2006, and SR is a mechanism that works both in somatosensory (Douglass et al 1993;Levin and Miller 1996) and auditory system signal transfer (Mangiore 2012). It should be explored whether auditory noise can reduce sway variability in people with instability due to central nervous system damage.…”

“…Subsensory mechanical noise chips applied to the soles of the feet have been shown to reduce postural sway in healthy aging adults, adults with sensorimotor deficits of central and peripheral causes (Priplata et al 2003(Priplata et al , 2006, and in healthy young adults (Priplata et al 2002). This shows that the presence of mechanical noise can reduce sway variability, which is thought to be a result of stochastic resonance (SR).…”

“…Subsensory mechanical noise was shown to increase sensory feedback from the feet. Because somatosensory noise improves postural sway (Priplata et al 2002(Priplata et al , 2003(Priplata et al , 2006, we hypothesized that auditory noise would also improve postural sway, due to a similar SR mechanism. There is evidence that auditory noise from a fixed location can improve postural stability in patients with cochlear implants, and that this could be due to the sound serving as an auditory field anchor (Mangiore 2012).…”

“…Perry (2006) concluded that both vibratory and touch detection thresholds decline with age: The loss of cutaneous sensation correlated with an impaired control of balance and an increased likelihood of falling. Other authors showed that applying vibration (Dhruv et al 2002;Priplata et al 2003;Priplata et al 2006) or rotary plantar massages (Bernard-Demanze et al 2004) to the foot soles enhances both cutaneous sensation (Dhruv et al 2002) and balance control (Maurer et al 2001;Bernard-Demanze et al 2004). Placing a raised edge underneath the perimeter of the plantar foot surface also facilitates postural stability (Maki et al 1999).…”

Balance problems are often related to a loss of plantar-sensitivity in elderly people. The purpose of this study was to explore the contribution of plantar cutaneous inputs induced by a spike support surface to the control of stance. Nineteen elderly (mean age 69.0 years, range 62-80) and 19 young adults (mean age 25.9 years, range 21-32) were instructed to stand (standing session) or to walk (walking session) for 5 min with sandals equipped with spike insoles (spike condition). Both sessions also involved a no spike condition in which participants stood or walked for 5 min without these insoles (no spike condition). In all conditions, postural responses were assessed during unperturbed stance and were performed (1) immediately after putting the spike or the no spike insoles, and (2) 5 min after standing or walking with them. Sway parameters, such as centre of foot pressure mean location, surface area, mean speed, root mean square and median frequency on the antero-posterior and medio-lateral axes, were calculated. As postural performances are often related to plantar-surface sensitivity, cutaneous sensitivity threshold was also evaluated with Semmes-Weinstein monofilaments.Although no immediate effect of the spike insoles was found, results indicated that standing or walking for 5 min with sandals equipped with spike insoles led to a significant improvement of quiet standing in the elderly. Balance improvement was also observed in young adults. The results provided evidence that wearing sandals with spike insoles can contribute, at least temporarily, to the improvement of unperturbed stance in elderly people with relatively intact plantar cutaneous sensation. Further research is needed to assess the effects of longer and discontinuous stimulations with spike insoles on postural control.

Vibrotactile sensitivity of patients with HIV‐related sensory neuropathy: An exploratory study

et al. 2018

BackgroundHIV‐associated distal polyneuropathy (HIV‐PN) affects large and small sensory nerve fibers and can cause tactile insensitivity. This exploratory study forms part of an effort to apply subsensory electrical nerve stimulation (SENS) to improve tactile sensitivity of patients with HIV‐PN. This work presented an opportunity to use a robust protocol to quantitatively describe the vibrotactile sensitivity of individuals with HIV‐PN on effective antiretroviral therapy (ART) and correlate these findings with commonly used clinical vibration testing and scoring grades.MethodsThe vibration perception thresholds (VPTs) of 20 patients with HIV‐PN at three vibration frequencies (25, 50, and 128 Hz) were measured. We compare the vibration perception threshold (VPT) outcomes to an age‐ and gender‐matched control cohort. We further correlated VPT findings with 128 Hz tuning fork (TF) assessments performed on the HIV‐PN participants, accrued as part of a larger study. HIV‐PN was defined as having at least one distal symmetrical neuropathic sign, although 18 of 20 had at least two neuropathic signs.ConclusionsHIV‐PN participants were found to have lower VPT sensitivity than controls for all three vibration frequencies, and VPT was more sensitive at higher vibration frequencies for both HIV‐PN and controls. VPT sensitivity was reduced with older age. Years on ART was correlated with VPT‐25 Hz but not with VPT in general. Notably, VPT sensitivity did not correlate with the clinically used 128 Hz TF severity grades. Outcomes of tests for interaction with vibration frequency suggest that HIV‐PN pathology does not affect all mechanoreceptors similarly.
