Abstract
This study aimed to investigate the acute effects of combining whole-body vibration with dynamic squats on cardiovascular and salivary bio-marker responses in healthy adults. A randomized crossover design was conducted with 20 healthy adults. Each participant underwent three exercise sessions, with a 2-week washout period between each session. The sessions consisted of: (1) whole-body vibration (VB) at 25 Hz for 2 minutes, with an amplitude of 2 mm, and 2 minutes of rest between sets, for a total of 5 sets; (2) dynamic squats (SQ) performed 15 times within 2 minutes, with a 2-minute rest between sets, for a total of 5 sets; and (3) a combination of whole-body VB and SQ (VB+SQ). The cardiovascular variables and salivary biomarkers related to exercise intensity were assessed. Only the VB+SQ session significantly decreased the unstimulated salivary flow rate, and caused greater changes in heart rate, systolic blood pressure, mean arterial pressure, rate-pressure product, and heart rate variability compared to VB or SQ alone. Moreover, the VB+SQ session significantly increased the salivary total protein concentration from 0.56±0.05 mg/mL (baseline) to 0.74± 0.06 mg/mL (postexercise condition) and the salivary alpha-amylase activity from 33.83±5.56 U/mL (baseline) to 63.63±12.33 U/mL (postexercise condition) (P<0.05). These changes were recovered at 1-hr postexercise condition. Our findings provide information for designing exercise programs that incorporate VB+SQ to enhance hemodynamic and cardiac autonomic responses in healthy adults and for application during rehabilitation periods.

Li Q, Liu P, Wang Z, Li X. Vibration therapy to improve pain and function in patients with chronic low back pain: a systematic review and meta-analysis. J Orthop Surg Res 2023; 18:727. [PMID: 37752526 PMCID: PMC10523661 DOI: 10.1186/s13018-023-04217-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 09/18/2023] [Indexed: 09/28/2023] Open
Abstract
BACKGROUND Vibration therapy (VT), a treatment of musculoskeletal disorders, has been developed for clinical applications in the past decade. However, its effect on relieving chronic low back pain (CLBP) and improving lumbar function is still illusive, lacking sufficient evidence-based medical data. OBJECTIVE This systematic review aimed to evaluate the efficacy of vibration therapy on pain and function in people with CLBP. METHODS PubMed, Cochrane Library, Web of Science, Embase, CNKI, Wanfang Date, VIP, and CBM were applied to search for clinical randomized controlled trials (RCTs) on vibration therapy for people with CLBP. The electronic databases were searched from the establishment of the database until July 1, 2023. Two researchers assessed the quality of the included studies and extracted data. The outcome indicators included the pain intensity index, Oswestry dysfunction index (ODI) score, and Roland-Morris dysfunction questionnaire (RMDQ) score. GRADE was used to evaluate the certainty of evidence of each outcome indicator. The meta-analysis was conducted using RevMan 5.3 software. RESULTS Fourteen papers met the inclusion criteria with 860 subjects (VT group n = 432 and control group n = 428). VT for patients with CLBP reduced the pain intensity index [SMD = - 0.71, 95% CI (- 1.02, - 0.39), I2 = 76%, P < 0.0001], the ODI score value [MD = - 4.24, 95% CI (- 8.10, - 0.38), I2 = 88%, P = 0.03], and the RMDQ score value [MD = - 2.21, 95% CI (- 3.41, - 1.01), I2 = 0%, P = 0.0003]. Subgroup analysis displayed that the pain intensity index was lower in the whole-body vibration (WBV) group than in the control group [SMD = - 0.49, 95% CI (- 0.79, - 0.19), I2 = 58%, P = 0.001] and the local vibration (LV) group [SMD = - 1.07, 95% CI (- 1.60, - 0.53), I2 = 76%, P < 0.0001]. The ODI scores in the WBV group were lower than those in the control group [MD = - 3.30, 95% CI (- 5.76, - 0.83), I2 = 36%, P = 0.009]. There was no statistically significant difference in ODI scores between the LV group and the control group [MD = - 5.78, 95% CI (- 16.23, 4.66), I2 = 97%, P = 0.28]. CONCLUSION The data from this study suggest that VT can reduce pain and improve lumbar function in patients with CLBP. However, we still need to carefully interpret the results of this study, as the certainty of evidence was low, and the clinical relevance of the results is questionable. Further RCTs are needed in the future to ascertain this.

Core and Whole-Body Vibration Exercise Improve Military Foot March Performance in Novice Trainees: A Randomized Controlled Trial. Mil Med 2023; 188:e254-e259. [PMID: 34259328 DOI: 10.1093/milmed/usab294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 06/22/2021] [Accepted: 07/07/2021] [Indexed: 01/11/2023] Open
Abstract
INTRODUCTION The purpose of the present study was to investigate core exercise training and whole-body vibration (WBV) as a training method to improve performance and recovery from an 8-km military foot march in novice trainees. MATERIALS AND METHODS A 3 × 5 repeated measures randomized control trial was used to evaluate the effects of core exercise training and WBV on performance and recovery from an 8-km foot march. Thirty-nine participants were randomized into three groups: core exercise (Ex), WBV with core exercise (WBVEx), and control. Each participant completed two 8-km foot marches (FM1 and FM2) with a 35 pound rucksack, separated by 4 weeks. Participants in the Ex and WBVEx groups completed 3 weeks of core exercise training, three times per week in between FM1 and FM2. Performance time, creatine kinase (CK), and interleukin-6 (IL-6) were measured. The Auburn University Institutional Review Board approved all aspects of this study (protocol number: 19-211 MR 1907). RESULTS Performance time (P < .001) and CK (P = .005) were significantly improved during FM2 as compared to FM1. The Ex (d = -0.295) and WBVEx (d = -0.645) treatments had a large effect on performance time. CK (P < .001) and IL-6 (P < .001) were significantly elevated at the completion of the foot march regardless of group. Only CK remained elevated for 2 days (P < .001) following the foot march. CONCLUSIONS Core exercise training with or without WBV improved 8-km foot march performance time by 5-6 minutes. The improvements are likely because of an increase in trunk stability. Additionally, this study showed that completing two identical foot marches a month apart increases performance and improves recovery.

Abstract
Several studies agree that mechanical vibration can induce physiological changes at different levels, improving neuromuscular function through postural control strategies, muscle tuning mechanisms and tonic vibration reflexes. Whole-body vibration has also been reported to increase bone mineral density and muscle mass and strength, as well as to relieve pain and modulate proprioceptive function in patients with osteoarthritis or lower back pain. Furthermore, vibratory training was found to be an effective strategy for improving the physical performance of healthy athletes in terms of muscle strength, agility, flexibility, and vertical jump height. Notably, several benefits have also been observed at the brain level, proving to be an important factor in protecting and/or preventing the development of age-related cognitive disorders. Although research in this field is still debated, certain molecular mechanisms responsible for the response to whole-body vibration also appear to be involved in physiological adaptations to exercise, suggesting the possibility of using it as an alternative or reinforcing strategy to canonical training. Understanding these mechanisms is crucial for the development of whole body vibration protocols appropriately designed based on individual needs to optimize these effects. Therefore, we performed a narrative review of the literature, consulting the bibliographic databases MEDLINE and Google Scholar, to i) summarize the most recent scientific evidence on the effects of whole-body vibration and the molecular mechanisms proposed so far to provide a useful state of the art and ii) assess the potential of whole-body vibration as a form of passive training in place of or in association with exercise.

Immediate Effects of Whole-Body Vibration Associated with Squatting Exercises on Hemodynamic Parameters in Sarcopenic Older People: A Randomized Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182211852. [PMID: 34831608 PMCID: PMC8617886 DOI: 10.3390/ijerph182211852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 11/04/2021] [Accepted: 11/06/2021] [Indexed: 11/17/2022]
Abstract
Whole-body vibration (WBV) exercises have recently been introduced as a nonpharmacological therapeutic strategy for sarcopenic older people. The present study aimed to evaluate the effect of WBV exercise on hemodynamic parameters in sarcopenic older people. Forty older people, divided into groups of nonsarcopenic (NSG = 20) and sarcopenic (SG = 20), participated in the study and were cross randomized into two interventions of eight sets of 40 s each, these being squatting with WBV and squatting without WBV. Heart rate (HR), peak heart rate (peak HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), double product (DP), mean arterial pressure (MAP), and subjective perception of effort (SPE), were assessed at baseline, during, and after a single WBV session. The HR, peak HR, and DP variables were similar at baseline between groups. WBV exercise increased all the hemodynamic parameters both during and immediately after the intervention, in both groups (SG and NSG). The MAP values were similar at baseline between groups; however, in the NSG there was a significant increase during and immediately after the squatting with WBV intervention (p < 0.05). The HR behavior, in both groups, showed that there was an increase in HR after the first set of exercises with vibration and this increase was maintained until the final set. The absence of adverse effects of WBV exercise on the cardiovascular system and fatigue suggests this exercise modality is adequate and safe for sarcopenic older people.

Abstract
OBJECTIVE To investigate the additive effects of whole-body vibration (WBV) training to the traditional physical therapy program (TPTP) on balance control, postural stability, and mobility after thermal burn injuries. DESIGN A single-blinded, randomized controlled study. SETTING Outpatient physical therapy setting. PARTICIPANTS Forty participants, 20-45 years old, with deep second-degree thermal burn involving the lower limbs and trunk, with 35%-40% total body service area, were randomly allocated either into the study group or the control group. INTERVENTION The study group received WBV plus TPTP while the control group received the TPTP only. Interventions were applied three sessions a week for eight weeks. OUTCOME MEASURES Anteroposterior stability index (APSI), mediolateral stability index (MLSI), overall stability index (OSI), timed-up and go (TUG), and Berg balance scale (BBS) were measured at baseline and after eight weeks of interventions. RESULTS There were statistically significant differences in APSI, MLSI, OSI, BBS, and TUG in favor of the WBV group after eight weeks of intervention (P < 0.001). After eight weeks of intervention, the mean (SD) for APSI, MLSI, OSI, BBS, and TUG scores were 1.87 ± 0.51, 41.36 ± 0.18, 1.95 ± 0.56, 47.2 ± 6.12, and 8.15 ± 1.05 seconds in the WBV group, and 2.41 ± 0.71, 2.21 ± 0.54, 2.68 ± 0.73, 40.65 ± 4.7, and 10.95 ± 2.44 seconds in the control group, respectively. CONCLUSIONS The whole-body vibration training combined with the TPTP was more beneficial in improving APS, MLS, OSI, TUG, and BBS than TPTP alone. It might be considered a useful adjunctive therapy in treating patients with healed wounds with a deep second-degree burn of the trunk and lower limbs.

Abstract
Background Whole body vibration (WBV) training as an intervention method can cure chronic low back pain (CLBP). Different WBV parameters exert different effects on lumbar-abdominal muscle performance. Currently, there is a lack of study researched the influence of WBV training on patients with CLBP by lumbar–abdominal muscle activity. Therefore, this study aimed to investigate how WBV and exercise and their interactions influence lumbar-abdominal muscle activity in patients with CLBP. Methods a group of ambulatory patients with chronic low back pain. Muscle activities of the multifidus (MF), erector spinae (ES), abdominal oblique externus muscle (AOE) and the rectus abdominis muscle (RA) were measured by surface electromyography, whereas participants performed 4 different exercises (single bridge, plank, side stay and V crunch) during three whole body vibration conditions and a no-vibration condition in a single experimental session. Results Compared with the same exercises without whole body vibration, muscle activity increased when whole body vibration was added to the exercises. MF; the WBV frequency (P = 0.002,) and exercise (P < 0.001) presented significant effects on the root mean square of MF, whereas exercise * frequency (P = 0.044) also resulted in significant interaction effects. ES: the significant differences were detected at WBV frequency (P < 0.001), exercise (P < 0.001), the interaction effect of exercise and frequency (P = 0.225) was no significant. RA: the significant difference was detected at WBV frequency (P = 0.018), the effect of exercise (P = 0.590) and the exercise * frequency interaction (P = 0.572) were no significant. AOE: the significant difference was detected at WBV frequency (P < 0.001), the effect of exercise (P = 0.152) and the exercise * frequency interaction (P = 0.380) were no significant. Conclusion Adding whole body vibration to exercise could increase muscle activation of lumbar–abdominal muscle in patients with CLBP. The optimum frequency for lumbar–abdominal muscles is 15 Hz. The best exercises include plank for multifidus and erector spinae, V crunch for rectus abdominis and single bridge for abdominal oblique externus.

Abstract
There are many adolescent patients complaining of low back pain, but research on it is lacking. The purpose of this study was to investigate the effects of trunk stabilization exercise combined with vibration on the pain, proprioception, and kinematics of the lumbar spine (LS) during sit to stand (STS) in adolescent patients with nonspecific low back pain (LBP). Fifty LBP patients were recruited and were randomly divided into two groups: Vibration group (n = 25) and placebo group (n = 25). All participants underwent 36-sessions of training consisting of six exercises. The Vibration group provided vibration stimulation during exercise, but the placebo group did not. The Numeric Pain Rating Scale (NPRS) and digital dual inclinometer were used to measure pain intensity and proprioception. The kinematics of the lumbar spine during STS were measured by motion capture system. After training, the pain and proprioception in the vibration group improved significantly greater than the placebo group (p < 0.05). The mobility of LS (maximum range of motion, angular velocity, lumbar to hip movement ratios) and lumbar-hip coordination during STS in the vibration group were significantly improved compared to the placebo group (p < 0.05). Thus, trunk stabilization exercise combined with vibration may be used to improve the pain, proprioception, and kinematic of the lumbar spine during sit to stand in adolescent patients with LBP.

Abstract
Background The postural stability is a major factor that helps prevent developing knee osteoarthritis with aging. The aim of this study was to investigate the effects of Baduanjin qigong on postural control and physical function in older adults with knee osteoarthritis. Methods Fifty-six individuals over 60 years of age with knee osteoarthritis were randomly assigned to either an experimental group (n = 28) or a control group (n = 28). Participants in the experimental group received a 12-week Baduanjin training, while those in the control group did not receive any additional physical exercise during the study period. The postural control was quantified by perimeter and ellipse area of center of pressure movement trajectory. The assessments were conducted three times (baseline, week 8, and week 12). Results The perimeter and ellipse area with both open- and closed-eyes conditions and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) function were significantly improved at week eight in the experimental group (p < 0.005). The ellipse area with open-eyes condition, WOMAC index, and stiffness and physical function domains were significantly decreased after the 12 weeks of Baduanjin training compared to the control group (p < 0.005). Only the perimeter area with both open- and closed-eyes conditions was not statistically significant at week 12 in the intervention group (p > 0.005). Conclusions Baduanjin is an effective and adjuvant therapy for older adults with knee osteoarthritis. Regular Baduanjin training can improve postural control and WOMAC function of old individuals with knee osteoarthritis. More advanced techniques and biopsychological measurements are required for further understanding of Baduanjin exercise in this population. The trial was registered in Chinese Clinical Trial Registry (ChiCTR-IOR-16010042).

Abstract
Whole-body vibration (WBV) can decrease arterial stiffness, but the effects of low-frequency WBV on arterial stiffness are not known. The aim of this study was to clarify the acute effects on arterial stiffness of WBV by vibration frequency. This study involved 9 healthy men (age: 31 ± 7 years). Each WBV session involved 3 sets of 4 different vibrations (0 Hz [control], 12 Hz, 20 Hz, 30 Hz) lasting 60 s with a 60-s inter-session rest interval. During WBV, the participants adopted a static squat position with their knees bent. An automatic oscillometric device was used to measure brachial-ankle pulse wave velocity (baPWV) before (baseline) and 5, 15, and 30 min after WBV. There was a significant decrease in baPWV from baseline at 30 min (P = .02) after WBV at 30 Hz. However, there was no change in baPWV at any time points after WBV at 0 (control), 12, and 20 Hz. These results suggested that low-frequency WBV does not affect arterial stiffness.

Abstract
Background: Knee osteoarthritis is a common disease affecting a large number of old individuals worldwide. This study aimed to explore the effects of Baduanjin Qigong in patients with knee osteoarthritis. Methods: Fifty participants with knee osteoarthritis were randomly assigned to either an experimental group (n = 25) or a control group (n = 25). Participants in the experimental group received Baduanjin Qigong training for 12 weeks, with three sessions per week lasting 40 min per session. Participants in the control group did not receive any additional physical training. All of participants completed outcome (proprioception, postural stability, and functional ability) assessments at three time points (baseline, Week 8, 12). Results: Proprioception and Western Ontario and McMaster Universities Osteoarthritis Index function were statistically improved at eighth and 12th week of the intervention in the Baduanjin Qigong group (p < 0.05), while the control group did not have any significant changes. For postural stability at the anterior-posterior direction with eyes closed, Baduanjin Qigong group showed significant improvement compared to controls after the 12 weeks of intervention (p < 0.05). Conclusions: Regular Baduanjin Qigong practice helped the improvement of knee joint proprioception and postural stability, and reduction of pain, stiffness, and functional impairments of old adults with knee osteoarthritis. Well-designed randomized controlled trials with long-term assessment are needed. The trial was registered in Chinese Clinical Trial Registry (ChiCTR-IOR-16010042).

Abstract
OBJECTIVE This study aimed to evaluate the effect of high and low frequency of whole body vibration (WBV) on repositioning error in 3 different angles of lumbar flexion in patients with chronic low back pain. METHODS Twenty-four participants with chronic low back pain, aged between 20 and 35 years, were included in this randomized crossover trial study. Participants were randomly assigned into 2 groups as follows: (1) low frequency/high frequency, and (2) high frequency/low frequency. Participants received high-frequency (50 Hz) and low-frequency (30 Hz) WBV in a semi-squat position for 5 minutes in 2 sessions, with 2 weeks of rest. Before and after the WBV, lumbar repositioning error in 30% and 60% of lumbar full flexion and neutral position with eyes closed when standing was evaluated using an electrogoniometer. RESULTS The repositioning error was decreased in neutral, 30%, and 60% of lumbar flexion after the low-frequency and high-frequency WBV. Post hoc testing revealed that the effect of angle was not significant in repositioning error changes between high-frequency and low-frequency WBV (P > .05). However, the effect of low-frequency WBV on the repositioning error was significantly higher compared with high-frequency WBV (P < .05). CONCLUSION Low-frequency WBV might induce more improvement in the accuracy of lumbopelvic repositioning compared with high-frequency WBV with the method of WBV used in this study.

Abstract
OBJECTIVE To confirm the benefits of whole-body vibration exercise for pain intensity and functional disability in patients with non-specific chronic low back pain. DESIGN Single-blind randomized controlled trial. SETTING Outpatient. SUBJECTS Eighty-nine patients with non-specific chronic low back pain met the inclusion criteria, they were randomly allocated to either the intervention group (n = 45) or the control group (n = 44). INTERVENTION The intervention group received whole-body vibration exercises three times a week for 12 weeks. The control group received general exercise protocol three times a week for 12 weeks. MAIN OUTCOMES The primary outcome measures were pain intensity and functional disability measured by the visual analog scale scores and Oswestry Disability Index. The secondary outcome measures included lumbar joint position sense, quality of life (Short Form Health Survey 36) and overall treatment effect (Global Perceived Effect). RESULTS A total of 84 subjects completed the 12-week study program. After 12 weeks, compared with the control group, the mean visual analog scale and Oswestry Disability Index scores decreased by additional 1 point (95% confidence interval (CI) = -1.22 to -0.78; P < 0.001), 3.81 point (95% CI, -4.98, -2.63; P < 0.001) based on adjusted analysis in the intervention group. And the intervention group provided additional beneficial effects for in terms of lumbar joint position sense (P < 0.05), quality of life (P < 0.05), and Global Perceived Effect (P = 0.012). CONCLUSION The study demonstrated that whole-body vibration exercise could provide more benefits than general exercise for relieving pain and improving functional disability in patients with non-specific chronic low back pain.

Abstract
BACKGROUND This study investigated how whole-body vibration (WBV), exercise, and their interactions influence core muscle activity in healthy young adults. MATERIAL AND METHODS Twenty-three healthy young adults (8 males and 15 females; age: 21.87±2.33 years) participated in the study. The activities of muscle multifidi (MM), rectus abdominis muscle (RM), erector spinae (ES), abdominis obliquus externus (AOE), and abdominis obliquus internus (AOI) were measured through surface electromyography (sEMG) while participants were performing 4 different exercise forms under 3 WBV conditions (condition 1: 5 Hz, 2 mm; condition 2: 10 Hz, 2 mm; and condition 3: 15 Hz, 2 mm) and a no-WBV condition in single experimental sessions. RESULTS The WBV frequency of 15 Hz is the best vibration stimulation for core muscles in all of the exercises (P<0.05). Single bridge is a better exercise for RM and AOE (P<0.05) compared with other exercises, and crunches is the best exercise for MM, AOI, and ES (P<0.05). Significant interaction effect was observed in different frequencies and exercises (P>0.05) except for AOI (F=0.990, P=0.378). CONCLUSIONS High vibration frequencies can lead to enhanced exercise benefits within an appropriate frequency range, and different exercises have diverse effects on various muscles. Single bridge and crunches are appropriate exercise forms for lumbar-abdominal muscles.

Abstract
BACKGROUND Nonspecific low back pain (NSLBP) accounts for a large proportion of low back pain cases. The present study aimed to investigate the effect of the whole-body vibration (WBV) exercise on lumbar proprioception in NSLBP patients. It was hypothesized that WBV exercise enhances lumbar proprioception. MATERIAL AND METHODS Forty-two patients with NSLBP performed an exercise program 3 times a week for a total of 12 weeks of WBV. The lumbar proprioception was measured by joint position sense. Outcomes were lumbar angle deviation and visual analogue scale (VAS) score. RESULTS After the 12-week WBV exercise, lumbar flexion angle deviation was reduced from 3.65±2.26° to 1.90±1.07° (P=0.0001), and extension angle deviation was reduced from 3.06±1.85° to 1.61±0.75° (P=0.0001), significantly lower than baseline. After participating in the 12-week WBV exercise, a significant pain reduction was observed (P=0.0001). Men in the whole group (n=32) indicated significantly lower angle deviations in flexion and extension, whereas women (n=10) indicated significantly lower flexion angle deviation (P=0.037), and no significant difference was found in extension angle deviation (P=0.052). However, by subdividing the entire group (n=42) into poor and good proprioceptive groups, WBV exercise presented significant enhancement of lumbar proprioceptive ability in the poor flexion proprioception subgroup, poor extension proprioception subgroup, and good extension proprioception subgroup (each P=0.0001), but not in the subgroup with good flexion proprioceptive ability (P=0.165). CONCLUSIONS Lumbar flexion and extension proprioception as measured by joint position sense was significantly enhanced and pain was significantly reduced after 12-week WBV exercise in NSLBP patients. However, the patients with good flexion proprioceptive ability had limited proprioceptive enhancement.

Abstract
BACKGROUND Low back pain (LBP) affects about 80% of the population at some time in their lives. Exercise therapy is the most widely used nonsurgical intervention for low back pain in practice. Thus, whole-body vibration (WBV) exercise is becoming increasingly popular in relieving musculoskeletal pain and in improving function. However, the efficacy of WBV exercise is not without dispute for low back pain. This meta-analysis, with its comprehensive and rigorous methodology, will provide better insight into this problem. METHODS Published articles will be identified using electronic searches from 1950 to 2018. The Cochrane Library, PubMed, Web of Science, Embase, CINAHL-Ebsco, PEDro, and China Biology Medicine will be searched for randomized controlled trials. Studies without a parallel comparison group will be excluded. Two reviewers will independently select relevant studies that investigate on WBV exercise for patients with LBP. Data extraction will be done independently by the same 2 reviewers who selected the studies. The primary outcome will be to assess pain, back-specific disability index, and adverse effect. Continuous data will be pooled by calculating the mean difference using the random-effects model. RESULTS The results of the final meta-analysis will provide an evidence of WBV exercise for low back pain. CONCLUSION This meta-analysis will provide a detailed summary of the evidence on the effects of WBV exercise on patients with LBP, in comparison with general exercise or without treatment. This review will benefit to researchers and policy makers who are interested in the treatment of LBP by WBV exercise.

Abstract
The purpose of this study was to examine the effects (a) of different whole-body vibration (WBV) accelerations when applied simultaneously during a set of squats on performance and perceived exertion and (b) of different linear increases and decreases of vibrations during the squats. It is a randomized, crossover experimental design. Undergraduate students (3 female; 16 male) participated. Each participant completed 5 laboratory sessions in this study (4 familiarization and 1 test session). The test session then had each participant complete one 20-second set of dynamics quarter-squats for 5 separate conditions followed by 5 minutes of rest. Squatting was performed at maximum speed from full extension knee with plantar-flexion ankle to a knee angle of 70° (0° = anatomic position) with dorsiflexion ankle. All sets were performed on the WBV platform in random order, where the 5 different conditions were (a) no WBV-sham, (b) 30 Hz (30 Hz low amplitude), (c) 50 Hz (50 Hz high amplitude), (d) 30-50 Hz (increasing frequency from 30 to 50 Hz; 1 Hz per second with high amplitude), and (e) 50-30 Hz (decreasing frequency from 50 to 30 Hz; 1 Hz per second). There was a significant decrease in the mean velocity of squatting performed during the 30- to 50-Hz condition compared with all other conditions (p ≤ 0.05). There were a significantly lower amount of repetitions performed during the 30- to 50-Hz exposure compared with the no-WBV and 30-Hz conditions. There was a significantly lower Rating of Perceived Exertion (RPE) during the 30-Hz condition compared with the no-WBV, 50-Hz, 30-50-Hz, and 50-30-Hz conditions.

Abstract
Background Whole-body vibration (WBV) exercise is widely used for training and rehabilitation. However, the optimal posture for training both the upper and lower extremities simultaneously remains to be established. Objectives The objective of this study was to search for an effective posture to conduct vibration from the lower to the upper extremities while performing WBV exercises without any adverse effects. Methods Twelve healthy volunteers (age: 22–34 years) were enrolled in the study. To measure the magnitude of vibration, four accelerometers were attached to the upper arm, back, thigh, and calf of each subject. Vibrations were produced using a WBV platform (Galileo 900) with an amplitude of 4 mm at two frequencies, 15 and 30 Hz. The following three postures were examined: posture A, standing posture with the knees flexed at 30°; posture B, crouching position with no direct contact between the knees and elbows; and posture C, crouching position with direct contact between the knees and elbows. The ratio of the magnitude of vibration at the thigh, back, and upper arm relative to that at the calf was used as an index of vibration conduction. Results Posture B was associated with a greater magnitude of vibration to the calf than posture A at 15 Hz, and postures B and C were associated with greater magnitudes of vibration than posture A at 30 Hz. Posture C was associated with a vibration conduction to the upper arm that was 4.62 times and 8.26 times greater than that for posture A at 15 and 30 Hz, respectively. Conclusion This study revealed that a crouching position on a WBV platform with direct contact between the knees and elbows was effective for conducting vibration from the lower to the upper extremities.

Abstract
This study aimed to compare the acute cardiovascular responses during and after resistance exercise with and without whole-body vibration. Nineteen sedentary adults randomly performed one session of isometric squats without vibration and the same exercise with vibration. Systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR), stroke volume (SV), cardiac output (CO) and systemic vascular resistance (SVR) were measured. SBP, DBP and HR were also measured for 20 min after the sessions. The exercise with vibration demonstrated significant values (P < 0.05) for SBP (second to sixth sets), DBP (third to sixth sets) and SVR (second to sixth sets) compared with the exercise without vibration. After the sessions, the values of SBP for both exercises were significantly lower than the respective resting values; with no difference between the sessions. In conclusion, exercise with vibration caused increases in SBP, DBP and SVR compared with exercise with no vibration in sedentary adults.
