“…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.

Efficacy of a Vibrating Crib Mattress to Reduce Pharmacologic Treatment in Opioid-Exposed Newborns

et al. 2023

ImportancePharmacologic agents are often used to treat newborns with prenatal opioid exposure (POE) despite known adverse effects on neurodevelopment. Alternative nonpharmacological interventions are needed.ObjectiveTo examine efficacy of a vibrating crib mattress for treating newborns with POE.Design, Setting, and ParticipantsIn this dual-site randomized clinical trial, 208 term newborns with POE, enrolled from March 9, 2017, to March 10, 2020, were studied at their bedside throughout hospitalization.InterventionsHalf the cohort received treatment as usual (TAU) and half received standard care plus low-level stochastic (random) vibrotactile stimulation (SVS) using a uniquely constructed crib mattress with a 3-hour on-off cycle. Study initiated in the newborn unit where newborns were randomized to TAU or SVS within 48 hours of birth. All infants whose symptoms met clinical criteria for pharmacologic treatment received morphine in the neonatal intensive care unit per standard care.Main Outcomes and MeasuresThe a priori primary outcomes analyzed were pharmacotherapy (administration of morphine treatment [AMT], first-line medication at both study sites [number of infants treated], and cumulative morphine dose) and hospital length of stay. Intention-to-treat analysis was conducted.ResultsAnalyses were performed on 181 newborns who completed hospitalization at the study sites (mean [SD] gestational age, 39.0 [1.2] weeks; mean [SD] birth weight, 3076 (489) g; 100 [55.2%] were female). Of the 181 analyzed infants, 121 (66.9%) were discharged without medication and 60 (33.1%) were transferred to the NICU for morphine treatment (31 [51.7%] TAU and 29 [48.3%] SVS). Treatment rate was not significantly different in the 2 groups: 35.6% (31 of 87 infants who received TAU) and 30.9% (29 of 94 infants who received SVS) (P = .60). Adjusting for site, sex, birth weight, opioid exposure, and feed type, infant duration on the vibrating mattress in the newborn unit was associated with reduction in AMT (adjusted odds ratio, 0.88 hours per day; 95% CI, 0.81-0.93 hours per day). This translated to a 50% relative reduction in AMT for infants who received SVS on average 6 hours per day. Among 32 infants transferred to the neonatal intensive care unit for morphine treatment who completed treatment within 3 weeks, those assigned to SVS finished treatment nearly twice as fast (hazard ratio, 1.96; 95% CI, 1.01-3.81), resulting in 3.18 fewer treatment days (95% CI, −0.47 to −0.04 days) and receiving a mean 1.76 mg/kg less morphine (95% CI, −3.02 to −0.50 mg/kg) than the TAU cohort. No effects of condition were observed among infants treated for more than 3 weeks (n = 28).Conclusions and RelevanceThe findings of this clinical trial suggest that SVS may serve as a complementary nonpharmacologic intervention for newborns with POE. Reducing pharmacotherapy with SVS has implications for reduced hospitalization stays and costs, and possibly improved infant outcomes given the known adverse effects of morphine on neurodevelopment.Trial RegistrationClinicalTrials.gov Identifier: NCT02801331
