Effect of Whole-body Vibration on Changing Foot Position and Postural Stability in Young Adults - Comparative Study.

Whole-body vibration is commonly used in physiotherapy. The vibration platform generates mechanical stimuli that primarily influence the neuromuscular system. Vibration can improve proprioception and balance. The aim of the study was to assess the impact of whole-body vibration on foot position and postural stability. A group of 31 participants took part in 6 vibration sessions at 15Hz and 30Hz over 2 weeks. Foot position parameters (angle and distance) and postural stability indicators before and after vibration were assessed on the Biodex Balance System. Vibration was performed on the Galileo Med35 platform (3x3 min). A control group consisted of 26 people who were only assessed on the Biodex platform. There was no change in the angle of both feet (p>0.05) after vibration at the frequency of 15 Hz. The angle of the right foot increased (p=0.013) after vibration at 30 Hz. Vibration increased the distance between the feet for both 15Hz (p=0.000) and 30Hz (p=0.000) sessions. There was no correlation between the change in feet spacing and the change in the overall stability index, anteroposterior stability index and mediolateral stability index (p>0.05). In the control group, no changes (p>0.05) in the angle and foot spacing were noted between consecutive measurements. 1. Whole body vibration can increase the width of quadrilateral of support in static conditions but has a minimal effect on changing the angle of the feet. 2. The width of the quadrilateral of support after whole-body vibration does not appear to affect postural stability under static conditions. 3. It is recommended that postural stability is assessed before and after whole body vibration while the initial position of the feet is maintained.

Effects of In-Wheel Suspension on Whole-Body Vibration and Comfort in Manual Wheelchair Users

Frequent and prolonged exposure to high levels of vibration and shock can cause neck and back pain and discomfort for many wheelchair users. Current methods to attenuate the vibration have shown to be ineffective and, in some cases, detrimental to health. Novel in-wheel suspension systems claim to offer a solution by replacing traditional spokes of the rear wheels with dampening elements or springs. The objective of this study was to investigate the effects of in-wheel suspension on reducing vibration and shock and improving comfort in manual wheelchair users. Twenty-four manual wheelchair users were propelled over nine different surfaces using a standard spoked wheel, a Spinergy CLX, and Loopwheels while accelerometry data was collected at the footrest, seat, and backrest. Loopwheels lowered vibrations by 10% at the backrest compared to the standard and CLX wheels (p-value < 0.001) and by 7% at the footrest compared to the CLX (p-value < 0.05). They also reduced shocks by 7% at the backrest compared to the standard wheel and CLX (p-value < 0.001). No significant differences were found in comfort between the wheels. Results indicate that Loopwheels is effective at reducing vibration and shock, but more long-term testing is required to determine effects on health.

Influence of physical exercise on respiratory muscle function in older adults: A systematic review and meta-analysis

Respiratory function decreases with aging. The literature showed that non-ventilatory specific exercise could have a positive impact on respiratory muscles. A systematic literature review was conducted to assess the effects of non-ventilatory specific exercise on maximal inspiratory (MIP) and expiratory pressure (MEP) and peak expiratory flow (PEF) in older adults. The included 9 trials investigated the effects of resistance training, yoga, Pilates, physical activity based on walking, and whole-body vibration training. The meta-analysis showed no statistically significant differences in MIP, MEP, and PEF after implementation of a non-ventilatory specific exercise program in older individuals. Between-study heterogeneity was substantial for MIP and MEP outcomes but it was not statistically significant for PEF. Further RCTs will be necessary to determine the effects of physical exercise interventions. PROSPERO registry CRD42023478262.

Modulation of Heart Rate Variability and Brain Excitability through Acute Whole-Body Vibration: The Role of Frequency.

This cross-over study aimed to explore effects of acute whole-body vibration (WBV) at frequencies of 5-35 Hz on heart rate variability and brain excitability. Thirteen healthy physically active college students randomly completed eight interventions under the following conditions: static upright standing without vibration (CON), static squat exercise (knee flexion 150°) on the vibration platform (SSE), and static squat exercise (knee flexion 150°) combined with WBV at vibration frequency of 5, 9, 13, 20, 25, and 35 Hz. Five bouts × 30 s with a 30-s rest interval were performed for all interventions. The brain's direct current potentials (DCPs), frequency domain variables (FDV) including normalized low frequency power (nLF), normalized high frequency power (nHF) and the ratio of LF to HF (LF/HF), along with the mean heart rate (MHR) were collected and calculated before and after the WBV intervention. Results suggested that WBV frequency at 5 Hz had a substantial effect on decreasing DCPs [-2.13 μV, t(84) = -3.82, p < 0.05, g = -1.03, large] and nLF [-13%, t(84) = -2.31, p = 0.04, g = -0.62, medium]. By contrast, 20-35 Hz of acute WBV intervention considerably improved DCPs [7.58 μV, t(84) = 4.31, p < 0.05, g = 1.16, large], nLF [17%, t(84) = 2.92, p < 0.05, g = 0.79, large] and the LF/HF [0.51, t(84) = 2.86, p < 0.05, g = 0.77, large]. A strong (r = 0.7, p < 0.01) correlation between DCPs and nLF was found at 5 Hz. In summary, acute WBV at 20-35 Hz principally activated the sympathetic nervous system and increased brain excitability, while 5-Hz WBV activated the parasympathetic nervous system and reduced brain excitability. The frequency spectrum of WBV might be manipulated according to the intervention target on heart rate variability and brain excitability.

Removal of movement artifacts and assessment of mental stress analyzing electroencephalogram of non-driving passengers under whole-body vibration.

The discomfort caused by whole-body vibration (WBV) has long been assessed using subjective surveys or objective measurements of body acceleration. However, surveys have the disadvantage that some of participants often express their feelings in a capricious manner, and acceleration data cannot take into account individual preferences and experiences of their emotions. In this study, we investigated vibration-induced mental stress using the electroencephalogram (EEG) of 22 seated occupants excited by random vibrations. Between the acceleration and the EEG signal, which contains electrical noise due to the head shaking caused by random vibrations, we found that there was a strong correlation, which acts as an artifact in the EEG, and therefore we removed it using an adaptive filter. After removing the artifact, we analyzed the characteristics of the brainwaves using topographic maps and observed that the activities detected in the frontal electrodes showed significant differences between the static and vibration conditions. Further, frontal alpha asymmetry (FAA) and relative band power indices in the frontal electrodes were analyzed statistically to assess mental stress under WBV. As the vibration level increased, EEG analysis in the frontal electrodes showed a decrease in FAA and alpha power but an increase in gamma power. These results are in good agreement with the literature in the sense that FAA and alpha band power decreases with increasing stress, thus demonstrating that WBV causes mental stress and that the stress increases with the vibration level. EEG assessment of stress during WBV is expected to be used in the evaluation of ride comfort alongside existing self-report and acceleration methods.

The Development of a High-Static Low-Dynamic Cushion for a Seat Containing Large Amounts of Friction

Exposure to whole-body vibration (WBV) has been shown to result in lower-back pain, sciatica, and other forms of discomfort for operators of heavy equipment. While WBV is defined to be between 0.5 and 80 Hz, humans are most sensitive to vertical vibrations between 5 and 10 Hz. To reduce WBV exposure, a novel seat cushion is proposed that optimally tunes a High-Static Low-Dynamic (HSLD) stiffness isolator. Experimental and numerical results indicate that the cushion can drastically increase the size of the attenuation region compared to a stock foam cushion. When placed on top of a universal tractor seat, the cushion is capable of mitigating vibrations at frequencies higher than 1.1 Hz. For comparison, the universal tractor seat with a stock foam cushion isolates vibrations between 3.4 and 4.1 Hz, as well as frequencies larger than 4.8 Hz. Friction within the universal seat is accurately modeled using the Force Balance Friction Model (FBFM), and an analysis is conducted to show why friction hinders overall seat performance. Finally, the cushion is shown to be robust against changes in mass, assuming accurate tuning of the preload is possible.

Balance Changes Following a Controlled Whole-Body Vibration Training: A Pilot Analysis Addressing Balance Control in Adult Women with Obesity

Background: The prevalence of obesity among older individuals has significantly increased in recent years, potentially doubling the risk of postural imbalance and falls. Controlled whole-body vibration (CWBV) training is considered an alternative/complementary therapy for fall prevention, but its mechanisms still require further investigation. Objectives: This study aimed to investigate the effects of CWBV on balance and fall risk among older adult women with obesity. Methods: Fifteen adult women over the age of 60 (mean age 68.55 ± 4.86, BMI: 30.57 ± 2.97) participated in this quasi-experimental study. They underwent CWBV training three times weekly for six weeks. Gait stability and balance were assessed using a gait analysis system before and after the intervention. Results: The results indicated a significant decrease in both static and dynamic balance parameters, except for the variability of velocity index (P = 0.9) and fear of falling (FES-I score, P = 0.56), after the intervention. Conclusions: CWBV training appears to be an effective method for improving static and dynamic balance parameters in older adult women. However, further research is necessary to explore different dosages and protocols of vibration training, incorporating more challenging/specialized proprioceptive exercises to potentially improve the fear of falling in this population.

WHOLE-BODY VIBRATION EFFECT ON MUSCLE ACTIVATIONS: WHICH ONE IS THE MOST EFFECTIVE, LOW FREQUENCY OR HIGH FREQUENCY?

Purpose: Whole Body Vibration (WBV) is a practice that passively applies mechanical oscillations to an individual from a support surface. The tonic vibration reflex response depends on the vibration localization, frequency, amplitude, and initial length of the muscle, but there is no consensus on what the optimal frequency should be. This study was conducted to examine the activation differences of lower extremity muscles at low and high frequencies during squat exercise on WBV. Methods: This study involved 16 healthy individuals (Age = 23.66 ± 2.33 years, Body Mass Index= 22.59 ± 3.86 kg/m2). WBV application was performed on a vertical vibration platform (GLOBUS Physioplate®). Participants performed static half-squats on WBV for 20 seconds under vibrating (20 Hz and 60 Hz; 2-3 mm amplitude) conditions. An 8-channel Electromyography (EMG) Noraxon MiniDTS system was used to measure the activation of the Gluteus Medius (GMed), Gluteus Maximus (GMax), Vastus Lateralis (VL), and Vastus Medialis (VM) muscles. Results: It was observed that there was a difference between the two frequencies for the activation of the VM, VL, and GMed muscles (p = 0.004, 0.001, 0.002, respectively). Vibration frequencies of GMed, VL, and VM muscle activities at high frequency were increased compared to low frequency. GMax did not show any statistically significant change between the two vibration conditions (p=0.013). Conclusions: Physiotherapists and trainers should prefer high frequencies in WBV applications, especially when they need to improve the neuromuscular response in the quadriceps and gluteus medius muscles.

Unlocking liver health: Can tackling myosteatosis spark remission in metabolic dysfunction-associated steatotic liver disease?

Myosteatosis is highly prevalent in metabolic dysfunction-associated steatotic liver disease (MASLD) and could reciprocally impact liver function. Decreasing muscle fat could be indirectly hepatoprotective in MASLD. We conducted a review to identify interventions reducing myosteatosis and their impact on liver function. Non-pharmacological interventions included diet (caloric restriction or lipid enrichment), bariatric surgery and physical activity. Caloric restriction in humans achieving a mean weight loss of 3% only reduces muscle fat. Lipid-enriched diet increases liver fat in human with no impact on muscle fat, except sphingomyelin-enriched diet which reduces both lipid contents exclusively in pre-clinical studies. Bariatric surgery, hybrid training (resistance exercise and electric stimulation) or whole-body vibration in human decrease both liver and muscle fat. Physical activity impacts both phenotypes by reducing local and systemic inflammation, enhancing insulin sensitivity and modulating the expression of key mediators of the muscle-liver-adipose tissue axis. The combination of diet and physical activity acts synergistically in liver, muscle and white adipose tissue, and further decrease muscle and liver fat. Several pharmacological interventions (patchouli alcohol, KBP-089, 2,4-dinitrophenol methyl ether, adipoRon and atglistatin) and food supplementation (vitamin D or resveratrol) improve liver and muscle phenotypes in pre-clinical studies by increasing fatty acid oxidation and anti-inflammatory properties. These interventions are effective in reducing myosteatosis in MASLD while addressing the liver disease itself. This review supports that disturbances in inter-organ crosstalk are key pathophysiological mechanisms involved in MASLD and myosteatosis pathogenesis. Focusing on the skeletal muscle might offer new therapeutic strategies to treat MASLD by modulating the interactions between liver and muscles.

Effect of whole-body vibration frequency on objective physical function outcomes in healthy young adults: Randomized clinical trial

IntroductionWhole-body vibration (WBV) is used to improve muscle function but is important to know if doses can affect the objective function outcomes. ObjectiveTo compare the effect of two frequencies of WBV on objective physical function outcomes in healthy young adults. MethodsForty-two volunteers were randomized into three groups: sham group (SG), and WBV groups with 30 (F30) and 45 Hz (F45). A 6-week WBV intervention protocol was applied by a vibrating platform twice a week, with the platform turn-off for SG and with two frequencies according to group, 30 or 45 Hz. The objective physical functions outcomes assessed were the proprioceptive accuracy, measured by proprioceptive tests, and quasi-static and dynamic balances, measured by Sensory Organization Test (SOT) and Y Balance Test, respectively. The outcomes were assessed before and after the WBV intervention. We used in the results comparisons, by GzLM test, the deltas percentage. ResultsAfter the intervention, no statistical differences were observed in percentage deltas for any outcomes (proprioceptive accuracy, quasi-static and dynamic balances). ConclusionObjective physical function outcomes, after the 6-week WBV protocol, did not present statistically significant results in any of the intervention groups (F30 or F45) and SG.

Frequency Transmission of Oscillation from External Whole-Body Vibration Platform to the Larynx

PurposeThis study investigates (1) the presence of frequency transmission of oscillation from an external whole-body vibration (WBV) platform to the larynx; and (2) the factors that influence this frequency transmission. MethodsThirty participants (mean age = 22.3 years) with normal voice were exposed to four frequency-intensity levels of WBV (10 Hz-10%, 10 Hz-20%, 20 Hz-10%, 20 Hz-20%) and were instructed to produce the natural vowel /a/ three times during each WBV setting. The frequency was extracted from the middle one-second of each electroglottographic (EGG) signal after passing through a Hann band filter with a range of 6-24 Hz. Linear mixed-effects models were applied to determine the factors that influenced the absolute deviation of the frequency transmission. ResultsAll participants exhibit an extracted EGG frequency that aligns with the external WBV frequency, deviating by -0.6 to 1.2 Hz. The absolute deviation of WBV frequency transmission is consistent for both sexes across various WBV settings, except the 10 Hz-10% setting where men tend to exhibit significantly higher deviations (p = 0.018). ConclusionOscillations at a specific frequency are transmitted from an external WBV platform to the larynx. This study proposes the use of a "spring" system to investigate the effect of WBV on the larynx, and recommends further research to explore the potential of WBV in managing voice disorders.

Balance Problems in the Elderly with Diabetes Mellitus: A Literature Review.

Diabetes mellitus (DM) is a syndrome of chronic metabolic disease which leads to all kinds of complications. Elderly people with DM have significantly higher fear of falling and balance problem scores as compared to those who did not have DM. This literature review aims: (1) to determine the risk factors for balance disorders in the elderly population with DM, (2) to describe valid and reliable balance measurement tools in the elderly population with DM, and (3) to describe the nonpharmacological management in dealing with balance disorders in the elderly population with DM. Several risk factors that cause balance disorders in the elderly with DM are related to complications of the disease they suffer, such as diabetic peripheral neuropathy, decreased sensory abilities, decreased motor skills, and decreased cognitive condition of the elderly with DM. Measuring instruments that can be used in the elderly population with DM to assess balance include the Mini-Balance Evaluation Systems Test, the Berg Balance Scale, and computerized measuring instruments with center of pressure analysis. Several nonpharmacological interventions are suggested in overcoming balance problems in the elderly with DM, including a combination of balance exercise and gait training, strength or resistance training, aquatic exercise, tai chi, yoga, technology-based exercise, electrotherapy, use of insoles, and whole-body vibrations.

Frictional vibration analysis of train braking system considering wheel-rail attachment and multi-body friction

Train vibration and noise have always been problems that affect the service life of relevant components and passenger comfort. This paper focuses on the vibration of the train braking system and establishes a torsional vibration model of the train braking system considering wheel-rail attachment and multi-body friction, which includes three rotational degrees of freedom of the brake disc, brake block, and wheelset. The periodic vibration and chaotic bifurcation of the braking system under low-speed working conditions are studied by numerical calculation. An optimization strategy is proposed for the chaotic bifurcation behavior, which eliminates the chaotic interval at low speeds through the reasonable matching of particle parameters, so as to ameliorate the brake groan problem of the train.

Biomechanical analysis of real‐time vibration exposure during mini combine harvester operation: A hybrid ANN–GA approach

AbstractThis research focuses on designing and evaluating ergonomic self‐propelled machinery seats to reduce whole‐body vibration (WBV) exposure among male and female agricultural workers. Subjects without musculoskeletal disorders were selected, and their anthropometric parameters were analyzed. An ergonomically refined seat, considering anthropometric dimensions and vibration reduction, was developed and tested. Vibration isolators using piezoelectric material enhanced operator comfort. In a laboratory experiment, real‐time one‐third octave band WBV data were collected using various seat types and engine speeds. At 1200 rpm, female operators experienced WBV levels between 3.42 and 13.40 m/s², while males ranged from 3.13 to 12.20 m/s². At 1600 rpm, females (T‐1) had WBV levels of 20.20–42.39 m/s², and males recorded 18.90–40.12 m/s². At 2000 rpm (T‐1), female operators WBV ranged from 246.71 to 303.45 m/s², and males from 248.10 to 300.13 m/s². At 2400 rpm (T‐1), female operators experienced WBV from 385.29 to 457.87 m/s², and males from 381.57 to 445.50 m/s². An integrated approach with artificial neural networks and genetic algorithms optimized machine operating parameters, resulting in minimum WBV levels. The highly accurate Multilayer Feed‐Forward Artificial Neural Network model (2‐10‐1) had a correlation (R) of 0.996 and a low mean‐squared error of 0.198. This research underscores the effectiveness of seat isolators in reducing vibrations and highlights the importance of considering both seat design and engine speed, especially concerning gender‐specific differences in vibration tolerance. It provides valuable insights for improving the comfort and safety of self‐propelled machinery operators in agriculture.

Effects of train vibration load on the structure and hydraulic properties of soils

Investigating the impact of train-induced vibration loads on soil hydraulic properties, this study conducted experiments using a self-designed indoor soil seepage platform that incorporates vibration loads. The experiments were complemented with scanning electron microscopy to analyze the influence of train-induced vibration loads on soil hydraulic conductivity and its evolutionary characteristics under different vibration frequencies. The experimental results indicated that as the vibration frequency increases from no vibration (0 Hz) to 20 Hz, the time required for the soil volumetric moisture content to reach its peak and stabilize decreases rapidly. However, after the vibration frequency exceeds 20 Hz, the rate at which the time required for the volumetric moisture content to reach its peak and stabilize decreases slows down. Furthermore, the soil pore water pressure increases with the increase in vibration frequency. At a vibration frequency of 80 Hz, the peak value of pore water pressure increases by 105% compared to the non-vibration state, suggesting that higher vibration frequencies promote the development and acceleration of soil pore moisture migration. Additionally, as the vibration frequency increases, the soil hydraulic conductivity initially experiences a rapid increase, with a growth rate ranging from 40.1 to 47.4%. However, after the frequency exceeds 20 Hz, this growth rate significantly decreases, settling to only 18.6% to 7.8%. When the soil was subjected to a vibration load, the scanning electron microscopy test revealed alterations in its pore structure. Micropores and small pores transformed into macropores and mesopores. Additionally, the microstructural parameters indicated that vibration load decreased the complexity of soil pores, thereby speeding up the hydraulic conduction process. This, in turn, affected the hydraulic properties of the soil and established a relationship between pore structure complexity and soil hydraulic properties.

Effects of the abdominal belt on the reduction of spinal forces and muscle activities during extreme transits of high-speed craft

Repeated high-g shocks and whole-body vibration (WBV) as experienced by operators of High-Speed Craft (HSC) increase the risk of fatigue, back pain, and acute and chronic injuries, especially in the lumbar region of the spine. Studies on abdominal belts have suggested their beneficial effects on lumbar torso stabilisation and back pain mitigation in both weight lifting and HSC scenarios. This paper presents a human musculoskeletal model to simulate belt effects for occupants on HSC under high-g shocks. Parameters included the shock severity with peak acceleration ranging from 3 g to 10 g, human dimensions and muscle strengths, the belt width and belt forces are investigated. The results show an average of 120% increase in the intra-abdominal pressure (IAP), a 9% reduction in the transverse abdominis activities, and a 12% reduction in the spinal compressive force at the L4/L5 joints when the abdominal belt is added to the human model. In conclusion, wearing an abdominal belt significantly assists abdominal muscles and maintains a solid core during intense WBV generated in different shock severity levels. It may cause a small negative influence on the neck region with a 2.4% increase in the shear force at the C4/C5 joints.

Effects of 12 weeks of inspiratory muscle training and whole body vibration on the inflammatory profile, BDNF and muscular system in pre-frail elderly women: A randomized controlled trial

Aimto investigate the effects of the whole body vibration (WBV) and inspiratory muscle training (IMT) on the inflammatory profile and in muscle mass and strength in pre-frail older women. Methodsthis study was a randomized double-blind trial. Forty two older women aged 60–80 years were randomly allocated to IMT + WBV (G1), IMTsham + WBV (G2) or Sham groups (G3). During 12 weeks G1 received both trainings, whereas G2 received WBV alone and G3 received IMT with a low fixed load and were positioned at the vibratory platform without therapeutic effect. Participants were evaluated before and after the intervention for the following outcomes: Brain-derived neurotrophic factor (BDNF) and inflammatory biomarkers (IB), respiratory (RT) and quadriceps thickness (QT) and diaphragmatic mobility (DM) using muscle ultrasound, body composition (BC) using a bioelectrical impedance scale and inspiratory muscle strength (IMS). Resultsafter the training, G1 (114.93 ± 21.29) improved IMS (p<0.005) compared with G2 (91.29 ± 23.10) and G3 (85.21 ± 27.02). There was also a significant improve on time of the DM (p<0.001) and RT (p=0.006) for G1 (8.59 ± 3.55 and 11.11 ± 12.66) compared with G2 (1.05 ± 3.09 and 1.10 ± 10.60) and G3 (0.40 ± 2.29 and -1.85 ± 7.45). BDNF, IB, QT and BC were similar between groups. ConclusionsIMT associated with WBV is effective to improve in increasing IMS, RT and DM in pre-frail older women. However, these interventions do not modify BDNF, IB, QT or BC in this population.

Finite element method-based study for spinal vibration characteristics of the scoliosis and kyphosis lumbar spine to whole-body vibration under a compressive follower preload

Purpose To analyze the dynamic response of the lumbosacral vertebrae structure of a scoliosis spine and a kyphosis spine under whole-body vibration. Methods Typical Lenke4 (kyphosis) and Lenke3 (scoliosis) spinal columns were used as research objects. A finite element model of the lumbosacral vertebrae segment was established and validated based on CT scanning images. Modal, harmonic response, and transient dynamic analyses were performed on the lumbar-sacral scoliosis model using the finite element software abaqus. Results The first four resonance frequencies of kyphosis spine extracted from modal analysis were 0.86, 1.45, 8.51, and 55.71 Hz. The first four resonance frequencies of scoliosis spine extracted from modal analysis were 0.76, 1.45, 10.51, and 63.82 Hz. The scoliosis spine had the maximum resonance amplitude in the transverse direction, while the kyphosis spine had the maximum resonance amplitude in the anteroposterior direction. The dynamic response in transient analysis exhibited periodic response over time at all levels. Conclusion The scoliosis and kyphosis deformity of the spine significantly complicates the vibration response in the scoliosis and kyphosis areas at the top of the spine. Scoliosis and kyphosis patients are more likely to experience vibrational spinal diseases than healthy people. Besides, applying vertical cyclic loads on a malformed spine may cause further rotation of scoliosis and kyphosis deformities.

Amelioration of Anxiety Associated with Opioid Withdrawal by Activation of Spinal Mechanoreceptors Via Novel Heterodyned Whole Body Vibration.

Opioid use disorder (OUD)-associated overdose deaths have reached epidemic proportions worldwide. An important driving force for relapse is anxiety associated with opioid withdrawal. We hypothesized that our new technology, termed heterodyned whole-body vibration (HWBV) would ameliorate anxiety associated with OUD. Using a randomized, placebo (sham)-controlled, double-blind study design in an NIH-sponsored Phase 1 trial, we evaluated 60 male and 26 female participants diagnosed with OUD and undergoing treatment at pain and rehabilitation clinics. We utilized the Hamilton Anxiety Scale (HAM-A) and a daily visual analog scale anxiety rating (1-10) to evaluate anxiety. Subjects were treated for 10 min 5X/week for 4 weeks with either sham vibration (no interferential beat or harmonics) or HWBV (beats and harmonics). The participants also completed a neuropsychological test battery at intake and discharge. In OUD subjects with moderate anxiety, there was a significant improvement in daily anxiety scores in the HWBV group compared to the sham treatment group (p=3.41 × 10-7). HAM-A scores in OUD participants at intake showed moderate levels of anxiety in OUD participants (HWBV group: 15.9 ± 1.6; Sham group: 17.8 ± 1.6) and progressively improved in both groups at discharge, but improvement was greater in the HWBV group (p=1.37 × 10-3). Furthermore, three indices of neuropsychological testing (mental rotations, spatial planning, and response inhibition) were significantly improved by HWBV treatment. These findings support HWBV as a novel, non-invasive, non-pharmacological treatment for anxiety associated with OUD.
