Effects of whole-body vibration training in patients with multiple sclerosis: A systematic review

IntroductionMultiple sclerosis (MS) is an autoimmune inflammatory disease of the central nervous system. MS is characterised by nerve demyelination that can alter nerve transmission and lead to such symptoms as fatigue, muscle weakness, and impaired motor function. There are 47000 people with MS in Spain. Vibration training can be an effective and complementary alternative to traditional exercise to treat patients with MS. The aim of this study was to analyse the effectiveness of vibration training programmes in patients with MS. DevelopmentWe searched 5 electronic databases (PubMed, SPORTDiscus, SciELO, Lilacs, IBECS, and ISI Web of Knowledge) in August 2015. By using a set of keywords, we found studies linking vibration training and MS and included randomised controlled trials that applied vibration training to patients with MS. Our search yielded 71 studies. Only 9 of them were included after removing duplicate studies and those which were not relevant according to our selection criteria. These studies obtained different outcomes. ConclusionsSome studies found improvements in muscle strength, functional capacity, coordination, resistance, balance, and some areas of 88-Item Multiple Sclerosis Spasticity Scale. However, we identified limitations in some of these studies and there are still few publications on vibration training and MS to ensure training effectiveness.

Effects of vibration training in reducing risk of slip-related falls among young adults with obesity

This study examined the effects of controlled whole-body vibration training on reducing risk of slip-related falls in people with obesity. Twenty-three young adults with obesity were randomly assigned into either the vibration or placebo group. The vibration and placebo groups respectively received 6-week vibration and placebo training on a side-alternating vibration platform. Before and after the training, the isometric knee extensors strength capacity was measured for the two groups. Both groups were also exposed to a standardized slip induced by a treadmill during gait prior to and following the training. Dynamic stability and fall incidences responding to the slip were also assessed. The results indicated that vibration training significantly increased the muscle strength and improved dynamic stability control at recovery touchdown after the slip occurrence. The improved dynamic stability could be resulted from the enhanced trunk segment movement control, which may be attributable to the strength increment caused by the vibration training. The decline of the fall rates from the pre-training slip to the post-training one was greater among the vibration group than the placebo group (45% vs. 25%). Vibration-based training could be a promising alternative or additional modality to active exercise-based fall prevention programs for people with obesity.

Effects of Vibration Training on Muscle Recovery and Exercise Induced Soreness: A Systematic Review

AbstractObjective The positive effects of vibration training (VT) on improving strength and muscle performance are widely documented; however, its ability and feature to diminish the effects of Delayed Onset Muscle Soreness (DOMS) and to initiate muscle recovery has not been thoroughly correlated. Data Sources Systematic literature searches for randomized controlled trials between 2009-2014 were performed in the databases of: SOLAR (CSS Library), CINAHL and PubMed between July15 to July 26, 2014. Study Selection and Data Extraction Five randomized controlled trials with a total of 163 subjects supported strong evidence with the use of VT to diminish DOMS. Data Synthesis and Conclusions The studies presented moderate evidence for the use of VT in muscle recovery parameters of: power, explosive muscle ability, return of strength and maximal voluntary isometric contraction as well as ROM. This review found no evidence on the effects of VT on limb circumference. Vibration Training (VT), when compared to exercise such as a standard sport cool down or treadmill walking, had no significant difference on the return of muscle function measured in terms of strength and power. The same studies however, showed VT had significantly faster recovery time compared to the control (no intervention) group.

Controlled Whole-body Vibration Training Reduces Risk Of Falls In People With Multiple Sclerosis

Despite the prevalence of falls among people with multiple sclerosis (MS), there are very limited evidence-based treatment approaches for fall prevention among this population. Controlled whole-body vibration (CWBV) training has recently emerged as a new modality to train older adults to reduce their risk of falls primarily because it is portable, safe, easy to use, and effective; and requires less intensive physical activity than traditional exercise-based methods. Nevertheless, there is a lack of evidence about the impact of CWBV training on reducing falls in people with MS. PURPOSE: To examine if an 8-week CWBV training protocol can reduce risk of falls in people with MS. METHODS: Twenty individuals (14 females) with MS (mean ± SD age: 52.0 ± 14.3 y/o, disease duration: 16.1 ± 11.5 y) underwent the vibration training 3 times per week for 8 weeks while standing on a side alternating vibration platform. Each session included 5 repetitions of 1-min vibration exposure followed by a 1-min seated rest. The vibration frequency and amplitude were 20 Hz and 3.2 mm, respectively. Their risk of falls was quantified by the isometric knee extensor muscle strength capacity (normalized to the body mass), the EquiScale balance scale, and Timed-Up-and-Go (TUG) test; and was evaluated pre and post the 8-week training. Paired t-tests were used to examine if the training improves these risk factors of falls. RESULTS: The knee extensor strength capacity on the affected side was significantly increased from 0.92 ± 0.51 Nm/kg for pre-training test to 1.06 ± 52.54 Nm/kg for the post-training test (p < 0.01). Compared to pre-training values, there was a significant improvement at post-training for body balance (11.00 ± 4.16 vs. 12.55 ± 3.31, p < 0.001) and TUG (14.92 ± 6.80 vs. 13.33 ± 5.63 s, p < 0.01). CONCLUSIONS:The findings of this study suggest that an 8-week vibration training program reduced risk of falls among individuals with MS by strengthening muscles, improving body balance, and enhancing functional mobility. The clinical application of CWBV may reduce falls for individuals with MS; however, more systematic studies based on large sample sizes are needed to examine the longitudinal effect of vibration training to reduce the number of real-life falls among persons with MS.

Effects of vibratory training on plantar impression in patients affected by stroke

Aim: The aim of this study was to investigate the effect of vibration training on plantar impression and motor function in patients affected by stroke. Methods: The sample consisted of 28 individuals with hemiparesis after stroke who were randomly assigned to the intervention group (n=18) and the control group (n=10). The instruments used for evaluation were the mini-mental state examination, photopodoscopy and the 6-minute walk test. For treatment, whole body vibration training was used three times a week for 8 weeks. The treatment was carried out in two phases. The first phase, which lasted for 4 weeks, consisted of four sets of exercises with 60 seconds of vibration. In the first exercise, the participants were in a static standing position, feet apart with knees flexed at 30°. In the second exercise, the same position was implemented, with knees flexed at 90°. In the third exercise, a standing position with one-leg support on the affected limb with flexed knee at 30°. The fourth exercise was a repetition of the first exercise. The second phase also lasted for 4 weeks. It consisted of the same exercises but the amount of sets of exercises was doubled. Results: Data were analysed by independent t-test and repeated measures ANOVA with two factors. There was no intergroup nor intragroup statistical difference (P=0.05) in the plantar impression area on the affected and unaffected side; there was only intragroup statistical differences in the 6-minute walk test (P=0.03). Conclusions: Whole-body vibration training did not influence the increase of the plantar impression area and motor function in stroke patients.

Does vibration training reduce the fall risk profile of frail older people admitted to a rehabilitation facility? A randomised controlled trial

Purpose: To determine the effect of Vibration Training (VT) on functional ability and falls risk among a group of frail older people admitted to an inpatient rehabilitation unit in a regional hospital in New Zealand. Method: A randomized controlled trial of 56 participants (mean 82.01 years in the intervention group and 81.76 years in the control group). VT targeting lower limb muscles with a frequency 30–50 Hz occurred three times per week until discharge. Amplitude progressively increased from 2 to 5 mm to allow the programme to be individually tailored to the participant. The control group received usual care physiotherapy sessions. Outcome measures were: Physiological profile assessment (PPA); and Functional Independence measure (FIM) and Modified Falls Efficacy Scale (MFES). Results: There was a statistically significant difference observed between the two groups in terms of FIM score (F = 5.09, p = 0.03) and MFES (F = 3.52, p = 0.007) but no difference was observed in terms of PPA scores (F = 0.96, p = 0.36). Conclusions: Among older people admitted to an inpatient rehabilitation facility there may be some beneficial effect to the use of VT in conjunction with usual care physiotherapy in terms of improved functional ability. The study design and the small dosage of VT provided may have precluded any change in falls risk among participants.Implications for RehabilitationVibration training (VT) may assist in reducing the risk of falling among at risk older people.Current pressures on health systems (ageing population, reduced hospital length of stay) necessitate the development of innovative strategies to maximise the rehabilitation potential of older people.Among older people admitted to an inpatient rehabilitation facility there may be some beneficial effect to the use of vibration training in conjunction with usual care physiotherapy in terms of improved functional ability.

Effect of Vibration Training on Anaerobic Power and Quardroceps Surface EMG in Long Jumpers

Objective: To explore the anaerobic power and surface EMG (sEMG) of quardrocep muscle in lower extremities after single vibration training intervention. Methods: 8 excellent male long jumpers voluntarily participated in this study. Four intervention modes were devised, including high frequency high amplitude (HFHA,30Hz,6mm), low frequency low amplitude(LFLA,15Hz,3mm), high frequency low amplitude (HFLA,30Hz,3mm), and non-vibration (CON). All subjects received a knee extensor maximal voluntary contraction (MVC) test before the vibration. After the test, a 5×1 min. vibration would be carried out and the subjects were asked to pedal. Results: Peak power and average power output of the four vibration treatment methods did not reach obvious level. There was no obvious difference in root-mean-square(RMS) EMG of the dominant leg among the four treatments. The RMS EMG of the non-dominant leg of HFLA method during peak power output was much higher than that of HFHA and CON . The quotient between root-mean-square and peak power of the four groups did not reach significant level. Conclusion: Single vibration could not improve the anaerobic performance of long jumpers and HFLA might decrease the work efficiency of the non-dominant leg muscle of excellent long jumpers participating anaerobic test.

The acute effects of vibration training on balance and stability amongst soccer players

Acute whole body vibration training (WBVT) is a tool used amongst coaches to improve performance prior to activity. Its effects on other fitness components, such as balance and stability, along with how different populations respond are less well understood. The aim of the current research is to determine the effect of acute WBVT on balance and stability amongst elite and amateur soccer players. Forty-four healthy male soccer players (22 elite and 22 amateur) were assigned to a treatment or control group. The intervention group then performed 3 × 60 seconds static squat on vibration platform at 40 Hz (±4 mm) with Y balance test (YBT) scores and dynamic postural stability index (DPSI) measured pre and post. DPSI was significantly lower in the elite players in the acute WBVT compared to amateur players (F1, 40= 6.80; P = 0.013). YBT anterior reach distance showed a significant improvement in both amateur and elite players in the acute WBVT group (F1, 40= 32.36; P < 0.001). The improvement in DPSI amongst the elite players indicates a difference in responses to acute high frequency vibration between elite and amateur players during a landing stability task. The results indicate that acute WBVT improves anterior YBT reach distances through a possible improvement in flexibility amongst both elite and amateur players. In conclusion, acute WBVT training appears to improve stability amongst elite soccer players in comparison to amateur players, the exact reasoning behind this difference requires further investigation.

Whole body vibration training for lower limb motor function among stroke patients

Background/aim Motor function impairment is a frequent problem in stroke patients and many questions remain about the application of vibration therapy for neurological patients. This study aims to verify the effects of vibration training on lower limb function in patients affected by stroke. Methods This was a clinical, prospective study. The study's subjects were selected via a convenience sample from Samuel Libanio Hospital's Physical Therapy and Neurology Out-patient clinics in Pouso Alegre, Brazil. The sample comprised of 27 individuals presenting with spastic hemiparesis due to stroke. Participants received whole body vibration training at a frequency of 50 Hz and 2 mm amplitude, for 8 weeks. In the first 4 weeks, participants underwent a series of four 60-second periods of vibration in the following positions: in orthostatic posture, first with the knees semi-flexed at 30°, then with the knees semi-flexed at 90°, and then with the affected knee semi-flexed at 30°, and finally in orthostatic posture again with the knees semi-flexed at 30°. In the last 4 weeks, we doubled the number of series of vibration, but used the same positions. The six minute walking test (6MWT), the stair climbing test (SCT) and the timed get up and go test (TUG) were applied to evaluate the lower members' motor function. The tests were applied before and after the intervention, as well as after a follow-up, which was performed 1 month later. Results This study found statistical differences in the 6MWT (P=0.00), SCT (P=0.00), and TUG (P=0.00), indicating improvement in the participants' lower limbs motor function. Conclusion Vibration therapy can contribute to the improvement of the lower limbs' motor function in patients affected by stroke.

Novel Vibration-Exercise Instrument With Dedicated Adaptive Filtering for Electromyographic Investigation of Neuromuscular Activation

Vibration exercise (VE) has been suggested as an effective methodology to improve muscle strength and power performance. Several studies link the effects of vibration training to enhanced neuromuscular demand, typically ascribed to involuntary reflex mechanisms. However, the underlying mechanisms are still unclear, limiting the identification of the most appropriate vibration training protocols. This study concerns the realization of a new vibration exercise system for the upper limbs. Amplitude, frequency, and baseline of the vibrating force, which is generated by an electromechanical actuator, can be adjusted independently. A second order model is employed to identify the relation between the generated force and the input voltage driving the actuator. Our results show a high correlation (0.99) between the second order model fit and the measured data, ensuring accurate control on the supplied force. The level of neuromuscular demand imposed by the system on the targeted muscles can be estimated by electromyography (EMG). However, EMG measurements during VE can be severely affected by motion artifacts. An adaptive least mean square algorithm is proposed to remove motion artifacts from the measured EMG data. Preliminary validation with seven volunteers showed excellent motion artifact removal, enabling reliable evaluation of the neuromuscular activation.

Effect of vibration versus suspension therapy on balance in children with hemiparetic cerebral palsy

Most cerebral palsy children have deficits in balance, co-ordination, and gait throughout childhood and adulthood. So, it is essential to seek an ideal physical therapy program to help in solving such widespread problem. The present study was conducted to compare between the effect of vibration training and suspension therapy on balance in children with hemiparetic cerebral palsy. Patients and methodsThirty children born with hemiparetic cerebral palsy from both sexes ranging in age from eight to ten years old were assigned into two groups of equal number. Study group I received vibration training in addition to a designed physical therapy program and study group II received suspension therapy in addition to the same physical therapy program given to the study group I. Stability indices were evaluated via using Biodex instrument system before and after six months of treatment. ResultsThe results revealed no significant difference when comparing the pre-treatment mean values of the two groups (study I and study II), while significant improvement was observed in all the measuring variables of the two groups when comparing their pre and post treatment mean values. Significant difference was also observed when comparing the post treatment results of the two groups in favor of the study group II. ConclusionSuspension therapy for children with hemiparetic cerebral palsy is an excellent supplement to regularly scheduled physical therapy intervention for the purpose of improving degree of stability in those patients.

Effects of vibration training on bone metabolism: results from a short-term bed rest study

The absence of mechanical loading leads to a prompt increase in bone resorption measured by bone resorption markers. There is high potential that vibration training can positively influence bone metabolism in immobilized subjects, reduce the increase in osteoclastic activity and increase bone formation processes. We investigated whether vibration training at 20 Hz with an amplitude of 2-4 mm influences bone metabolism during immobilization. Eight male subjects (26.4 ± 4.9 years; 78.1 ± 9.5 kg) performed a 14 day bed rest in 6°-head down tilt (HDT). Subjects received vibration training for 2 × 5 min/day or a control intervention without vibration (crossover design). Calcium excretion and bone resorption markers C-telopeptide (CTX) and N-telopeptide (NTX) were analyzed from 24 h urine samples. Bone formation markers, bone alkaline phosphatase (bAP) and procollagen-N propeptide (PINP) were analyzed from fasting blood samples. Our results show an increase in bone resorption very early during HDT bed rest in both interventions (CTX: p < 0.01; NTX: p < 0.001). Vibration training did not have any different effect on bone resorption markers (CTX: p = 0.10; NTX: p = 0.58), bone formation markers (PINP: p = 0.21; bAP: p = 0.12) and calcium excretion (p < 0.64) compared to the control condition. Mere vibration training with 20 Hz for 2 × 5 min/day does not prevent increase in bone resorption as measured with the described methods in our short-term HDT bed rest.

Efectos musculoesqueléticos del entrenamiento con vibraciones en ancianos

A vibration platform is increasingly being used in geriatric centers for exercise in older people. Studies centered on the effects of vibration training recommend this exercise mode as a therapeutic alternative for prevention and/or improvement of osteoporosis and sarcopenia. Nowadays, neither the physiological mechanisms involved on adaptive responses of exposure to vibration are not well defined nor the parameters of vibration more indicated to maximizing the benefits. This paper presents a review of the main studies centered on the effects of vibration training on the musculoskeletal system.

Effects of Vibration Training on Force Production in Female Basketball Players

The goal of this research project was to investigate the long-term effects of whole-body vibration (WBV) training on force production. Thirty-one female basketball players were randomly distributed in an experimental group: VG (vibration) and a control group: CG (no vibration). Both groups participated in the same training program; however, the experimental group (VG) performed a set of exercises on a vibration platform (Power Plate) at 30- to 35-Hz frequency and 4 mm amplitude, whereas the CG performed the same exercises at 0 Hz. Muscle performance of the legs was tested on a contact-time platform (Ergojump, Finland) through several tests: squat jump (SJ), countermovement jump (CMJ), and 15-second maximal performance jump; squat leg power (knee extension) was also evaluated using an Ergopower machine (Bosco, Italy). After 14 weeks, there was a significant increase (p < 0.001) from initial to final tests in both groups (CG and VG) in SJ, CMJ, 15 seconds, and squat leg power. However, there were no significant differences between the VG and the CG for any of the parameters evaluated. The findings of this study indicate that WBV training has no additive or discernible effect on the strength development of female basketball players after several weeks of use, suggesting that the application of this technology has no advantages over traditional strength training methods.

Effects of Vibration Training on Muscle Power: A Meta-Analysis

The purpose of this meta-analysis was to attempt to gain a clear picture of the magnitude of adaptations in muscular power expected after acute and chronic training, as well as identify specific factors that influence the treatment effects. Studies using a power training intervention and containing data necessary to calculate effect size (ES) were included in the analysis a total of 30 studies. Effect size demonstrated that the type of vibration platform used is a moderator of the treatment effect of vibration on power development is the type of vibration platform employed. Differences were noted in both acute and chronic changes in power when vertical vibration platforms were compared with oscillating platforms. Vertical platforms elicit a significantly larger treatment effect for chronic adaptations (ES = 0.99) as compared with oscillating platforms (ES = 0.36). The data also show that age is a moderator of the response to vibration exercise for power. On the basis of the overall analysis, it is apparent that vibration exercise can be effective at eliciting chronic power adaptations. Exercise professionals can include vibration exercise as a means of fostering power improvements.

Effects of Vibration Training on Muscle Strength: A Meta-Analysis

The purpose of this meta-analysis was to attempt to gain a clear picture of the magnitude of strength improvements expected after acute and chronic vibration training and to identify specific factors that influence the treatment effects. Studies employing a strength training intervention and containing data necessary to calculate effect size (ES) were included in the analysis. A total of 31 studies met the inclusion criterion. Analysis of ES demonstrated that the type of vibration platform employed is a moderator of the treatment effect of vibration on strength development. Differences were noted in both acute and chronic changes in muscle strength when vertical vibration platforms are compared with oscillating platforms. Vertical platforms elicit a significantly larger treatment effect for chronic adaptations (ES = 1.24) compared with oscillating platforms (ES = -0.13). However, oscillating platforms elicit a greater treatment effect for acute effects (ES = 0.24) compared with vertical platforms (ES = -0.07). The data also show that gender, training status, and exercise protocol are moderators of the response to vibration exercise for strength development (vertical platforms). Based on the overall analysis, it is apparent that vibration exercise can be effective at eliciting chronic muscle strength adaptations. The vibration exercise can be used by exercise professionals to enhance muscular strength.
