RESUMO

BACKGROUND: Physiotherapy, including vibration-assisted therapy, has been proven to be effective for patients with ataxic cerebral palsy. Herewith, we studied the effect of a functional, goal-oriented interval rehabilitation program, including vibration-assisted home-training on the motor function of children with congenital ataxias. PATIENTS: 45 children (mean age 7.7 years, SD 4.70) with ataxia, having received a 6-month home-based side-alternating vibration-assisted therapy combined with intensive, goal-oriented, functional rehabilitation intervals, were included in the study, classified according to the progressive or non-progressive ataxia character. METHOD: Retrospective analysis of the prospectively collected data of the registry of the Cologne rehabilitation program "Auf die Beine". Motor abilities have been assessed prior to the intervention (M0), after 6 months of home-training (M6) as well as in a follow-up 6 months later (M12). We performed a gait analysis, a 1-minute walking test (1-MWT), and the Gross Motor Function Measure (GMFM-66). RESULTS: The GMFM-66 improvement (M6-M0 vs. M12-M6) was statistically significant with median improvement of 2.4 points (non-progressive) and 2.9 points (progressive) respectively, and clinically relevant. The 1-MWT improvement was statistically significant and clinically relevant for non-progressive ataxia. CONCLUSION: The intensive training, including vibration-assisted therapy significantly improved the motor function of children with ataxia. Six months later the skills were preserved in children with progressive ataxia and could be further developed in non-progressive forms.

RESUMO

PURPOSE: To investigate the effect of intermittent vibration at different intervals on bone fracture healing and optimize the vibration interval. METHODS: Ninety sheep were randomized to receive no treatment (the control group), incision only (the sham control group), internal fixation with or without metatarsal fracture (the internal fixation group), and continuous vibration in addition to internal fixation of metatarsal fracture, or intermittent vibration at 1, 2, 3, 5, 7 and 17-day interval in addition to internal fixation of metatarsal fracture (the vibration group). Vibration was done at frequency F=35 Hz, acceleration a=0.25g, 15 min each time 2 weeks after bone fracture. Bone healing was evaluated by micro-CT scan, bone microstructure and mechanical compression of finite element simulation. RESULTS: Intermittent vibration at 7-day interval significantly improved bone fracture healing grade. However, no significant changes on microstructure parameters and mechanical properties were observed among sheep receiving vibration at different intervals. CONCLUSIONS: Clinical healing effects should be the top concern. Quantitative analyses of bone microstructure and of finite element mechanics on the process of fracture healing need to be further investigated.

RESUMO

PURPOSE: To identify the effects of whole body vibration (WBV) on health-related quality of life (HRQOL) in patients with chronic conditions. METHODS: Five databases (the Cochrane Library, PubMed, Medline, EBSCO, and Web of science) were searched (from inception until April 30, 2019) for original articles. All studies were randomized controlled trials reporting the effects of WBV on HRQOL. Two independent reviewers extracted trial data and assessed the risk of bias using the risk of bias tool recommended by the Cochrane Back Review Group. RESULTS: Of the 349 articles that were screened, 17 articles, including 763 participants with various chronic conditions, met the inclusion criteria. Six studies reported significant improvements in HRQOL. No evidence was observed to suggest that WBV was more effective than other types of exercises. The study participants, exercise protocols, HRQOL instruments, study duration, and frequency as well as amplitude of WBV varied across the studies. Meta-analysis was not conducted due to the heterogeneity of study designs and outcome measures. CONCLUSIONS: This study has demonstrated that WBV may improve HRQOL in patients with chronic conditions. However, the evidence was not strong enough to warrant recommendation and thus further high-quality studies with larger sample sizes and longer intervention durations are needed.

RESUMO

The purpose of this research was to study the effects of a whole-body vibration (WBV) warm-up for improving fencers' performance on variables derived from a lunge reaction test, the 10-meter sprint, and the countermovement jump. We compared fencer performances at four time intervals: (a) preintervention, (b) immediately postintervention, (c) 1-minute postintervention, and (d) 2-minute postintervention. Study participants were 16 male fencers. The vibration frequency was 30 Hz, and its amplitude was two mm. After each WBV session, participants significantly improved their performance on all measures at both one and two minutes after the intervention. Specifically, lunge reaction tests scores improved by 5.50% and 7.34%, respectively, relative to preintevention testing (p < .01), peak power output improved by 4.94% and 11.52%, respectively (p < .05), and maximum rate of force development improved by 13.41% and 18.38%, respectively (p < .01). Acute WBV (frequency = 30 Hz, peak-to-peak amplitude of two mm) induced neuromuscular activation and improved lunge reaction scores, agility, and power.

RESUMO

INTRODUCTION: The aim of this study was to evaluate the effects of mechanical vibration and low-level laser therapy on orthodontic pain after placement of the initial archwire. METHODS: Sixty subjects with 3-6 mm maxillary dental crowding, a nonextraction fixed treatment plan, and no medical history were included in this study. The subjects were randomly divided into 3 groups, equally distributed by sex. In each subject, preadjusted edgewise appliances were placed in the maxillary arch from the left first molar to the right first molar, and a 0.014-inch round nickel-titanium archwire was fully engaged with elastomeric ties and cut at the end of first molar bondable tube. In group 1 (mean age 13.98 ± 2.68 y), mechanical vibration was performed 3 times: immediately, 24 hours, and 48 hours after engagement of the initial archwire. In group 2 (mean age 14.86 ± 2.06 y), low-level laser therapy was applied once: immediately after the insertion of the initial archwire. Group 3 (mean age 14.41 ± 1.78 y) served as the control group. Pain scores were determined with the use of a visual analog scale (VAS). RESULTS: Although no statistically significant differences were found among the groups (P >0.05), the mean VAS scores for the mechanical vibration group were consistently lower than those of the control and low-level laser therapy groups at all measured time points. CONCLUSIONS: The mechanical vibration group had lower, though nonsignificant, VAS scores for all measured time points. Additional clinical trials are recommended for more definitive conclusions.

RESUMO

BACKGROUND: This pilot study was to examine the feasibility and tolerance of whole body vibration therapy (WBVT) for children and adults with moderate severity of cerebral palsy (CP) being graded as levels III or IV on the Gross Motor Function Classification Scale (GMFCS). METHODS: Study participants received the additional WBVT when standing still on the vibration platform for three 3-min bouts of vibration (20 Hz, 2 mm amplitude), 4 days per week for 4 weeks. In addition to questions relating to feasibility and participants' opinions, assessment at baseline and completion of the intervention included the Gross Motor Function Measure-66 Item Set (GMFM-66 IS), 2-min walk test (2MWT), Timed Up and Go test (TUG) and Pediatric Evaluation of Disability Inventory (PEDI). Wilcoxon Signed Ranks test was used to compare the results. RESULTS: Fourteen participants (mean age = 25.25 years SD 3.71; 9 males, 64%; GMFCS level III n = 13, 92%) were recruited and completed the study. The attendance rate was over 90% with no adverse events. All participants tolerated the protocol which was satisfactorily delivered in a clinical setting. CONCLUSIONS: The present WBVT protocol was feasible, safe and well-tolerated by the participants with moderate severity of CP, justifying future studies with larger samples and more rigorous study design. TRIAL REGISTRATION: The present study has been registered under the ClinicalTrials.gov (NCT03375736) and the date of registration commenced on 18 December 2017.

RESUMO

Background: Whole-body vibration has been used to improve motor function in chronic stroke patients, but its effect on patients with subacute strokes remains unclear. Objectives: We explored the effect of whole-body vibration on patients with subacute strokes. Methods: Participants were randomly allocated to a whole-body vibration (WBV) group (n = 30) or an upper- and lower-cycle (ULC) group (n = 30). Both groups received occupational therapy after these interventions. All participants received treatment for 30 min/day, 5 days/week, for 4 weeks. Both groups received the same conventional physical therapy. Results: The manual function test (MFT) score and grip strength improved after both WBV (p = 0.001 and p = 0.001, respectively) and ULC (p = 0.002 and p = 0.001, respectively), but the improvement was more pronounced (MFT p = 0.016; GS p = 0.023) after WBV. Conclusions: These findings suggest that the use of WBV and ULC was effective as remedial treatments for improving upper extremity motor function and increasing grip strength for patients with subacute strokes. The improvement was more pronounced for the WBV treatment. This trial is registered with KCT0003246.

RESUMO

BACKGROUND: People with Multiple sclerosis (MS) have been found to impair strength and endurance of core muscles compared with healthy people. Whole body vibration (WBV) is a relatively new method of neuromuscular training which can induce positive effects on mobility and postural control of MS patients. OBJECTIVE: To evaluate the effects of a 6-week WBV training program on the strength and endurance of core muscles in patients with MS. METHODS: Fifty patients were allocated to two groups, one receiving WBV training (intervention) and one no treatment (control). The endurance of core muscles were evaluated using Sorensen, flexion, and side bridge endurance tests. The strength of core muscles was evaluated using a dynamometer. We used the quality of life-54 questionnaire (MSQOL-54) to evaluate patients` quality of life aspects at baseline and two months after the end of study. RESULTS: Forty six patients completed the study (mean age: 37.9 ±â€¯7.7; BMI: 23.8 ±â€¯4.3). All outcome measures including strength and endurance of core muscles as well as MSQOL-54 scores significantly improved in WBV group in comparison to control group. While the within-group comparison showed significant improvement in the WBV group (P < 0.001), in the control group, some outcomes measures including physical and mental components of MSQOL-54 deteriorated (P < 0.001) over the course of study. CONCLUSIONS: Our study shows that strength and endurance of core muscles as well as quality of life of MS patients can be positively influenced by a 6-week WBV training. The program was well-tolerated by patients and no adverse event was observed.

RESUMO

Botulinum toxin is the most commonly performed facial cosmetic procedure and pain at the injection site is a frequent patient concern. While various topical interventions have been described for analgesia, there have not been any studies comparing different techniques. We compared the use of a vibratory stimulus, ice pack application, and no intervention on injection site pain for cosmetic botulinum toxin injection. A prospective-, randomized-, individual-controlled study was conducted using a visual analog scale to assess pain. Patients received bilateral glabellar injections, with randomization into unilateral vibration, unilateral ice application, or vibration and ice on either side. We analyzed 88 injections on 22 patients. Mean visual analog scores were 26.5 (standard deviation [SD]: 23.1) among injections with vibration, 24.4 (SD: 22.9) with ice, and 29.4 (SD: 27.1) without analgesia. There was no significant difference in pain scale scores with the use of vibration, ice, or no topical anesthesia (P = .737). Further, pain scale scores did not differ significantly between medial and lateral injections nor did patients have a reduction in pain on either side of the forehead regardless of which method was used. While there may be a role for topical interventions to improve injection site analgesia, we maintain that consistently proper technique plays a greater role in improving patient tolerance. Future studies will continue to investigate the role of topical anesthesia in cosmetic facial injections and address patient-specific factors contributing to discomfort.

RESUMO

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.

RESUMO

BACKGROUND: Interferon gamma (IFN-γ) is a clinically relevant immunomodulatory cytokine that has demonstrated significant potential in the treatment and management of respiratory diseases such as tuberculosis and pulmonary fibrosis. As with all large biomolecules, clinical translation is dependent on effective delivery to the disease site and delivery of IFN-γ as an aerosol offers a logical means of drug targeting. Effective localization is often hampered by instability and a lack of safe and efficient delivery systems. The present study sought to determine how effectively IFN-γ can be nebulized using two types of vibrating mesh nebulizer, each with differing mesh architectures, and to investigate the comparative efficiency of delivery of therapeutically active IFN-γ to the lungs. METHODS: Nebulization of IFN-γ was carried out using two different Aerogen vibrating mesh technologies with differing mesh architectures. These technologies represent both a standard commercially available mesh type (Aerogen Solo®) and a new iteration mesh (Photo-defined aperture plate (PDAP®). Extensive aerosol studies (aerosol output and droplet analysis, non-invasive and invasive aerosol therapy) were conducted in line with regulatory requirements and characterization of the stability and bioactivity of the IFN-γ post-nebulization was confirmed using SDS-PAGE and stimulation of Human C-X-C motif chemokine 10 (CXCL 10) also known as IFN-γ-induced protein 10KDa (IP 10) expression from THP-1 derived macrophages (THP-1 cells). RESULTS: Aerosol characterization studies indicated that a significant and reproducible dose of aerosolized IFN-γ can be delivered using both vibrating mesh technologies. Nebulization using both devices resulted in an emitted dose of at least 93% (100% dose minus residual volume) for IFN-γ. Characterization of aerosolized IFN-γ indicated that the PDAP was capable of generating droplets with a significantly lower mass median aerodynamic diameter (MMAD) with values of 2.79 ± 0.29 µm and 4.39 ± 0.25 µm for the PDAP and Solo respectively. The volume median diameters (VMD) of aerosolized IFN-γ corroborated this with VMDs of 2.33 ± 0.02 µm for the PDAP and 4.30 ± 0.02 µm for the Solo. SDS-PAGE gels indicated that IFN-γ remains stable after nebulization by both devices and this was confirmed by bioactivity studies using a THP-1 cell model in which an alveolar macrophage response to IFN-γ was determined. IFN-γ nebulized by the PDAP and Solo devices had no significant effect on the key inflammatory biomarker cytokine IP-10 release from this model in comparison to non-nebulized controls. Here we demonstrate that it is possible to combine IFN-γ with vibrating mesh nebulizer devices and facilitate effective aerosolisation with minimal impact on IFN-γ structure or bioactivity. CONCLUSIONS: It is possible to nebulize IFN-γ effectively with vibrating mesh nebulizer devices without compromising its stability. The PDAP allows for generation of IFN-γ aerosols with improved aerodynamic properties thereby increasing its potential efficiency for lower respiratory tract deposition over current technology, whilst maintaining the integrity and bioactivity of IFN-γ. This delivery modality therefore offers a rational means of facilitating the clinical translation of inhaled IFN-γ.

RESUMO

This study aimed at investigating the expression of osteoblast and chondrocyte-related genes in mesenchymal stem cells (MSCs), derived from rabbit adipose tissue, under mechanical vibration. The cells were placed securely on a vibrator's platform and subjected to 300 Hz of sinusoidal vibration, with a maximum amplitude of 10 µm, for 45 min per day, and for 14 consequent days, in the absence of biochemical reagents. The negative control group was placed in the conventional culture medium with no mechanical loading. The expression of osteoblast and chondrocyte-related genes was investigated using real-time polymerase chain reaction (real-time PCR). In addition, F-actin fiber structure and alignment with the help of actin filament fluorescence staining were evaluated, and the level of metabolic activity of MSCs was determined by the methyl thiazolyl tetrazolium assay. The real-time PCR study showed a significant increase of bone gene expression in differentiated cells, compared with MSCs (P < 0.05). On the other hand, the level of chondrocyte gene expression was not remarkable. Applying mechanical vibration enhanced F-actin fiber structure and made them aligned in a specific direction. It was also found that during the differentiation process, the metabolic activity of the cells increased (P < 0.05). The results of this work are in agreement with the well-accepted fact that the MSCs, in the absence of growth factors, are sensitive to low-amplitude, high-frequency vibration. Outcomes of this work can be applied in cell therapy and tissue engineering, when regulation of stem cells is required.

RESUMO

This double-blind, two-arm parallel randomized controlled trial investigated the effects of gamma-frequency rhythmic sensory stimulation on fibromyalgia. We were interested in whether rhythmic sensory stimulation would promote significant changes in fibromyalgia and associated symptoms, and whether treatment effects would differ between two distinct treatment parameters. Fifty patients with a formal diagnosis of fibromyalgia were randomly assigned to two test groups. One group received vibrotactile stimulation from a continuous sine wave single-frequency stimulation (40 Hz) for 30 minutes, five days per week, over five weeks, concomitant with usual care. The second group completed the same treatment protocol but received a different stimulation, consisting of random and intermittent complex wave gamma-range vibrotactile stimulation. Fibromyalgia symptoms, pain severity and interference, depression symptoms, quality of life and sleep quality were assessed at baseline and post-intervention. Results indicated that there were statistically significant changes from baseline to post-treatment in measures of fibromyalgia symptom severity, pain interference, depression, and sleep quality. However, treatment outcomes did not differ significantly between groups. These findings provide preliminary evidence that gamma-frequency rhythmic vibroacoustic stimulation may decrease fibromyalgia symptoms and ease associated comorbidities, opening new avenues for further investigation of the effects of rhythmic sensory stimulation on chronic pain conditions.

RESUMO

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.

RESUMO

BACKGROUND As most of the existing whole-body vibration (WBV) training programs provide vertical or rotatory vibration, studies on the effects of horizontal vibration have rarely been reported. The present study was conducted to investigate the effect of WBV in the horizontal direction on balance and gait ability in chronic stroke survivors. MATERIAL AND METHODS This study was designed as a randomized controlled trial. Twenty-one stroke survivors were randomly allocated into 2 groups (whole-body vibration group [n=9] and control group [n=12]). In the WBV group, WBV training in the horizontal direction was conducted for 6 weeks, and a conventional rehabilitation for 30 min, 3 days per week for a 6-week period, was conducted in both the WBV and control groups. Outcome variables included the static balance and gait ability measured before training and after 6 weeks. RESULTS On comparing the outcome variables before and after training in the WBV group, significant differences were observed in the cadence and single support time of gait ability. However, there were no significant differences in other variables, including velocity, step length, stride length, and double support time. In addition, after training, no significant differences in all variables were observed between the 2 groups. CONCLUSIONS The results of this study suggest that WBV training in the horizontal direction has few positive effects on balance and gait function in chronic stroke survivors. However, further investigation is needed to confirm this.

RESUMO

Many dermatologic procedures are painful and traumatic, for both pediatric patients and providers alike. Vibration anesthesia has recently been discussed as an effective method for reducing pain associated with injections, but some vibration machines can be cost prohibitive for providers. We describe how to employ an electric toothbrush as an inexpensive and effective option to provide vibration anesthesia during painful pediatric procedures.

RESUMO

BACKGROUND: Upper extremity functional impairments are common consequences of stroke. Therefore, continuous investigation of effective interventions for upper extremity functions after stroke is a necessity. Segmental muscle vibration (SMV) is one of the interventions that incorporate sensory stimulation to improve motor cortical excitability. The aim of this study was to investigate the influence of 5-minute SMV application along with supervised physical therapy (SPT) on improving activities of daily living and motor recovery on the hemiparetic upper extremity in patients with stroke. METHODS: A sample of 37 patients poststroke (29 males) was randomly allocated to either SPT control group (n = 18) or SPT and SMV (SPT-SMV) experimental group (n = 19). All patients received 3 sessions per week of SPT for 8 weeks. The SPT-SMV experimental group received SMV at the end of each SPT session. Outcome measures used were Barthel index (BI), modified Ashworth scale, manual muscle testing, and goniometry for range of motion (ROM) assessment. RESULTS: Thirty-four patients completed the study. Patients in both groups improved significantly after treatment in BI, elbow ROM, and elbow muscles strength. However, muscle tone in elbow joint of the hemiplegic upper extremity improved significantly after SMV only in the experimental group (SPT-SMV). CONCLUSION: The SPT intervention can improve functional outcomes of upper extremity in people after stroke. However, using SMV may have superior effect on improving muscle tone after stroke.

RESUMO

Tendinopathy is a very common disease in the general population as well as in athletes. The aim of the present study was to examine the tendon thickness and cross-sectional area (CSA) in subjects with chronic mid-portion Achilles tendinopathy (AT) who engaged in either an eccentric exercise (EE) programme with vibration training or an EE programme combined with cryotherapy. A sample of 61 patients with chronic mid-portion AT were recruited and divided into two groups: EE programme vibration training (n = 30) and EE programme combined with cryotherapy (n = 31). Three ultrasound assessments were performed: pre-intervention and at 4, and at 12 weeks. The comparison of thickness and CSA measures at baseline, 4, and 12 weeks showed a significant (P < 0.05) increase at 0, 2, 4, and 6 cm in maximal isometric contraction and at rest in subjects with chronic mid-portion AT. The EE vibration training resulted in a statistically significant CSA increase compared with the cryotherapy group in patients with chronic mid-portion AT.

RESUMO

PURPOSE: Although sleep bruxism (SB) is one of the most important clinical problems in dental practice, there is no definitive method for controlling it. This pilot study evaluated the effects of contingent vibratory feedback stimuli using an occlusal splint for inhibition of sleep bruxism. METHODS: Thirteen subjects with clinically diagnosed SB participated after providing an informed consent. Portable polysomnographic recordings were conducted in the subjects' home environment to make a definitive SB diagnosis and to evaluate the effects of the vibratory stimuli on SB. A force-based bruxism detection system, which used a pressure-sensitive piezoelectric film embedded in the occlusal splint, was utilized to trigger vibration feedback stimuli, which was scheduled to be applied intermittently for 30 min, at 30-min intervals. RESULTS: The number of SB episodes (times/hour), the total SB duration (seconds/hour), the mean duration of SB episodes (seconds/episode), and the micro-arousal index (times/hour) were scored for each time period (with and without vibration). The effects of the vibration on these scores were tested (paired t test; p < 0.05). The number of SB episodes tended to decrease with the vibration stimuli, and the decrease in the total SB duration was statistically significant (14.3 ± 9.5 vs. 26.0 ± 20.0, p = 0.03). No substantial change was found in terms of the micro-arousal index. CONCLUSIONS: These study results suggested that the SB inhibitory system employing a vibratory stimulus might be able to suppress the total SB duration without disturbing sleep.

RESUMO

OBJECTIVES: Vibration, in the form of high frequency acceleration (HFA), stimulates alveolar bone formation under physiologic conditions and during healing after dental extractions. It is not known if HFA has an anabolic effect on osteoporotic alveolar bone. Our objective is to determine if HFA has a regenerative effect on osteoporotic alveolar bone. METHODS AND MATERIALS: Adult female Sprague-Dawley rats were divided into five groups: 1) Ovariectomized Group (OVX), 2) Sham-OVX Group that received surgery without ovariectomy, 3) OVX-HFA Group that was ovariectomized and treated daily with HFA, 4) OVX+Static Force Group that was ovariectomized and received the same force as HFA, but without vibration, and 5) Control Group that did not receive any treatment. All animals were fed a low mineral diet for 3 months. Osteoporosis was confirmed by micro-CT of the fifth lumbar vertebra and femoral head. HFA was applied to the maxillary first molar for 5 minutes/day for 28 and 56 days. Maxillae were collected for micro-CT, histology, fluorescent microscopy, protein and RNA analysis, and three-point bending mechanical testing. RESULTS: Micro-CT analysis revealed significant alveolar bone osteoporosis in the OVX group. Vibration restored the quality and quantity of alveolar bone to levels similar to the Sham-OVX group. Animals exposed to HFA demonstrated higher osteoblast activity and lower osteoclast activity. Osteogenic transcription factors (RUNX2, Foxo1, Osterix and Wnt signaling factors) were upregulated following vibration, while RANKL/RANK and Sclerostin were downregulated. HFA did not affect serum TRAcP-5b or CTx-1 levels. The osteogenic effect was highest at the point of HFA application and extended along the hemimaxillae this effect did not cross to the contra-lateral side. CONCLUSIONS: Local application of vibration generated gradients of increased anabolic metabolism and decreased catabolic metabolism in alveolar bone of osteoporotic rats. Our findings suggest that HFA could be a predictable treatment for diminished alveolar bone levels in osteoporosis patients.
