Abstract
Schizophrenia is a complex neuropsychiatric disorder with significant morbidity. Treatment options that address the spectrum of symptoms are limited, highlighting the need for innovative therapeutic approaches. Gamma Entrainment Using Sensory Stimulation (GENUS) is an emerging treatment for neuropsychiatric disorders that uses sensory stimulation to entrain impaired oscillatory network activity and restore brain function. Aberrant oscillatory activity often underlies the symptoms experienced by patients with schizophrenia. We propose that GENUS has therapeutic potential for schizophrenia. This paper reviews the current status of schizophrenia treatment and explores the use of sensory stimulation as an adjunctive treatment, specifically through gamma entrainment. Impaired gamma frequency entrainment is observed in patients, particularly in response to auditory and visual stimuli. Thus, sensory stimulation, such as music listening, may have therapeutic potential for individuals with schizophrenia. GENUS holds novel therapeutic potential to improve the lives of individuals with schizophrenia, but further research is required to determine the efficacy of GENUS, optimize its delivery and therapeutic window, and develop strategies for its implementation in specific patient populations.

Abstract
The purpose of this report is to remind providers of the potential risks of Whole Body Vibration Therapy (WBVT) for children with disabilities. We reviewed the current state of knowledge and learned that WBVT may have potential risk of injury for some children. To the best of our knowledge this review is the first to clarify WBVT risks. We believe WBVT may have therapeutic value but we recommend caution and offer suggestions for future research.

Abstract
Aged individuals and astronauts experience bone loss despite rigorous physical activity. Bone mechanoresponse is in-part regulated by mesenchymal stem cells (MSCs) that respond to mechanical stimuli. Direct delivery of low intensity vibration (LIV) recovers MSC proliferation in senescence and simulated microgravity models, indicating that age-related reductions in mechanical signal delivery within bone marrow may contribute to declining bone mechanoresponse. To answer this question, we developed a 3D bone marrow analog that controls trabecular geometry, marrow mechanics and external stimuli. Validated finite element (FE) models were developed to quantify strain environment within hydrogels during LIV. Bone marrow analogs with gyroid-based trabeculae of bone volume fractions (BV/TV) corresponding to adult (25%) and aged (13%) mice were printed using polylactic acid (PLA). MSCs encapsulated in migration-permissive hydrogels within printed trabeculae showed robust cell populations on both PLA surface and hydrogel within a week. Following 14 days of LIV treatment (1g, 100 Hz, 1 hour/day), type-I collagen and F-actin were quantified for the cells in the hydrogel fraction. While LIV increased all measured outcomes, FE models predicted higher von Mises strains for the 13% BV/TV groups (0.2%) when compared to the 25% BV/TV group (0.1%). Despite increased strains, collagen-I and F-actin measures remained lower in the 13% BV/TV groups when compared to 25% BV/TV counterparts, indicating that cell response to LIV does not depend on hydrogel strains and that bone volume fraction (i.e. available bone surface) directly affects cell behavior in the hydrogel phase independent of the external stimuli. Overall, bone marrow analogs offer a robust and repeatable platform to study bone mechanobiology.

Abstract
Objective Previous studies on side-alternating vibration therapy (sVT) have usually used a 9 min intervention protocol. We performed a feasibility study aimed at assessing the safety, acceptability, and potential effectiveness of a longer sVT protocol (15 min per session) in children and adolescents with cerebral palsy (CP). Methods Fifteen participants aged 5.2-17.4 years (median = 12.4 years) with CP GMFCS level II underwent 20 weeks of sVT consisting of 15 min sessions 4 days/week. Participants were assessed at baseline and after the intervention period, including mobility (six-minute walk-test; 6MWT), body composition (whole-body dual-energy x-ray absorptiometry scans), and muscle function (force plate). Results Adherence level to the 15 min VT protocol was 83% on average. There were no adverse events reported. After 20 weeks, there was some evidence for an increase in the walking distance covered in 6MWT (+43 m; p = 0.0018) and spine bone mineral density (+0.032 g/cm2; p = 0.012) compared to baseline. Conclusions The 15 min sVT protocol is feasible and well tolerated. The results also suggest potential benefits of this protocol to mobility and bone health. Randomized controlled trials are needed to reliably ascertain the potential effectiveness of a longer sVT protocol on physical function and body composition in young people with CP.

Abstract
PURPOSE Systematically review the effect of exercise and motor interventions on physical activity and motor outcomes of adults with cerebral palsy (CP). METHODS Eight databases were searched. RESULTS Twenty-five studies were included, representing 439 adults with CP. Very low to low quality evidence supports that gait training is more effective than standard care or neurodevelopmental treatment for improving gait velocity, quality of gait, and ankle stiffness; balance training is more effective than seated therapeutic activities for improving walking self-confidence and perceived change in balance; whole-body vibration is no more effective than resistance training for improving strength or gait function; and resistance training is no more effective than a person's typical exercise program for improving strength or gait function of adults with CP. Adverse events were reported for balance training, functional training, resistance training, and whole-body vibration. DISCUSSION Further research is needed that is adequately powered and uses well-controlled study designs.

Addressing gross motor function by functional repetitive neuromuscular magnetic stimulation targeting to the gluteal muscles in children with bilateral spastic cerebral palsy: benefits of functional repetitive neuromuscular magnetic stimulation targeting the gluteal muscles. Front Neurol 2023; 14:1161532. [PMID: 37564737 PMCID: PMC10410564 DOI: 10.3389/fneur.2023.1161532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/20/2023] [Indexed: 08/12/2023] Open
Abstract
Background Impaired selective motor control, weakness and spasticity represent the key characteristics of motor disability in the context of bilateral spastic cerebral palsy. Independent walking ability is an important goal and training of the gluteal muscles can improve endurance and gait stability. Combining conventional physical excercises with a neuromodulatory, non-invasive technique like repetitive neuromuscular magnetic stimulation probably enhances effects of the treatment. This prospective study aimed to assess the clinical effects of repetitive neuromuscular magnetic stimulation in combination with a personalized functional physical training offered to children and adolescents with bilateral spastic cerebral palsy. Methods Eight participants Gross Motor Function Classification System level II and III (10.4 ± 2y5m; 50% Gross Motor Function Classification System level II) received a personalized intervention applying functional repetitive neuromuscular magnetic stimulation (12 sessions within 3 weeks; 12,600 total stimuli during each session). At baseline and follow up the following assessments were performed: 10-m-walking-test, 6-min-walking-test, GMFM-66. Six weeks after the end of treatment the patient-reported outcome measure Gait Outcome Assessment List was completed. Results GMFM-66 total score improved by 1.4% (p = 0.002), as did scoring in domain D for standing (1.9%, p = 0.109) and domain E for walking, jumping and running (2.6%, p = 0.021). Gait speed or distance walked during 6 min did not improve from baseline to follow up. Patient-reported outcome showed improvement in 4 patients in altogether 14 ratings. Caregiver-reported outcome reported benefits in 3 participants in altogether 10 ratings. Conclusion Repetitive neuromuscular magnetic stimulation promises to be a meaningful, non-invasive treatment approach for children and adolescents with bilateral spastic cerebral palsy that could be offered in a resource-efficient manner to a broad number of patients. To further investigate the promising effects of repetitive neuromuscular magnetic stimulation and its mechanisms of action, larger-scaled, controlled trials are needed as well as comprehensive neurophysiological investigations.

Abstract
Aims: To evaluate the feasibility and acceptability of vibration therapy (VT) in preschool children with cerebral palsy (CP) and obtain preliminary data on its potential effectiveness.Methods: Nine children aged 2.5-4.8 years (4 boys) with CP GMFCS levels I-III participated in a single-group feasibility study, undergoing a 12-week control period without intervention, followed by 12 weeks of home-based VT (four times/week, 9 min/day, frequency 20 Hz). We assessed adherence to VT protocol, adverse events, and family acceptability of VT. Clinical assessments included motor function (GMFM-66), body composition (DXA), mobility (10-meter walk/run test), and health-related quality of life (PedsQL).Results: VT was well tolerated and acceptable to families, with high adherence levels reported (mean = 93%). There were no observed between-period differences (ΔControl vs ΔVT) except for an improvement in the PedsQL "Movement & Balance" dimension with VT (p = 0.044). Nonetheless, changes after the VT but not the Control period were suggestive of potential treatment benefits for mobility, gross motor function, and body composition (lean mass and legs bone mineral density).Conclusion: Home-based VT is feasible and acceptable for preschool children with CP. Our preliminary data suggest potential health benefits from VT for these children, supporting larger randomized trials to assess its effectiveness properly.

Vibration therapy in young children with mild to moderate cerebral palsy: does frequency and treatment duration matter? A randomised-controlled study. BMC Pediatr 2023; 23:4. [PMID: 36593455 PMCID: PMC9806818 DOI: 10.1186/s12887-022-03786-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Accepted: 12/05/2022] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Vibration therapy (VT) has been increasingly studied in children with cerebral palsy (CP) over the last years, however, optimal therapeutic VT protocols are yet to be determined. The present study compared the effects of side-alternating VT protocols varying in frequency and treatment duration on the health of young children with mild-to-moderate CP. METHODS Thirty-four participants aged 6.0 to 12.6 years with CP acted as their own controls and underwent two consecutive study periods: a 12-week lead-in (control) period prior to the intervention period of 20-week side-alternating VT (9 min/session, 4 days/week), with the frequency either 20 Hz or 25 Hz, determined by randomisation. Participants had 4 assessment visits: baseline, after the control period, after 12-week VT (12VT), and after further 8 weeks of VT (20VT). Assessments included 6-minute walk test (6MWT); dual-energy x-ray absorptiometry; gross motor function; muscle function testing on the Leonardo mechanography plate and by hand-held dynamometry, and a quality-of-life questionnaire (CP QOL). Analysis was carried out using linear mixed models based on repeated measures. RESULTS Side-alternating VT was well-tolerated, with occasional mild itchiness reported. The median compliance level was 99%. VT led to improvements in 6MWT (+ 23 m; p = 0.007 after 20VT), gross motor function in standing skills (+ 0.8 points; p = 0.008 after 12VT; and + 1.3 points; p = 0.001 after 20VT) and in walking, running and jumping skills (+ 2.5 points; p < 0.0001 after 12VT; and + 3.7 points; p < 0.0001 after 20VT), spine bone mineral density z-score (+ 0.14; p = 0.015 after 20VT), velocity rise maximum of the chair rising test (+ 0.14 m/s; p = 0.021 after 20VT), force maximum of the single two-leg jump test (+ 0.30 N/kg; p = 0.0005 after 12VT; and + 0.46 N/kg; p = 0.022 after 20VT) and in the health module of CP QOL (+ 7 points; p = 0.0095 after 20VT). There were no observed differences between the two VT frequencies (i.e., 20 Hz vs 25 Hz) on study outcomes. CONCLUSIONS The study confirms that side-alternating VT has positive effects on mobility, gross motor function, body composition, muscle function, and quality of life, independent of VT frequencies tested. Long-term, 20VT appears to be a more efficient treatment duration than a short-term, 12VT. TRIAL REGISTRATION Australian New Zealand Clinical Trials Registry ACTRN12618002026202 ; 18/12/2018.

Abstract
BACKGROUND Ambulant children with cerebral palsy (CP) undertake physiotherapy to improve balance and walking. However, there are no relevant clinical guidelines to standardize usual physiotherapy care in the United Kingdom. A consensus process can be used to define usual physiotherapy care for children with CP. The resulting usual care checklist can support the development of clinical guidelines and be used to measure fidelity to usual care in the control groups of trials for children with CP. METHODS Twelve expert physiotherapists were recruited. In Phase 1, statements on usual care were developed using a survey and two nominal groups. Phase 2 included a literature review to support usual physiotherapy interventions. Phase 3 used a confirmatory survey, which also captured changes to provision during the COVID-19 pandemic. Consensus was calculated by deriving the mean of the deviations from the median score (MDM). High consensus was deemed to be where MDM < 0.42. RESULTS Physiotherapists reached high consensus on five outcome measures (MDM range 0-0.375) and nine areas of assessment (MDM range 0-0.25). Physiotherapists reached moderate consensus on task-specific training (MDM = 0.75), delivered at weekly intensity for 4-6 weeks (MDM = 0.43). There was high consensus (MDM = 0) that children should participate in modified sport and fitness activities and that children with Gross Motor Function Classification System Level III should be monitored on long-term pathways (MDM = 0.29). CONCLUSIONS Physiotherapists reached consensus on two usual care interventions, and a checklist was developed to inform the control groups of future randomized controlled trials. Further consensus work is required to establish clinical guidelines to standardize usual physiotherapy care in the United Kingdom.

Acute effects of quadriceps muscle versus tendon prolonged local vibration on force production capacities and central nervous system excitability. Eur J Appl Physiol 2022; 122:2451-2461.

Abstract
PURPOSE The present study aimed to directly compare the effects of 30 min muscle (VIBmuscle) vs. tendon (VIBtendon) local vibration (LV) to the quadriceps on maximal voluntary isometric contraction (MVIC) and rate of torque development (RTD) as well as on central nervous system excitability (i.e. motoneuron and cortical excitability). METHODS Before (PRE) and immediately after (POST) LV applied to the quadriceps muscle or its tendon, we investigated MVIC and RTD (STUDY #1; n = 20) or vastus lateralis (VL), vastus medialis (VM) and rectus femoris (RF) electromyography responses to thoracic electrical stimulation (TMEPs; motoneuron excitability) and transcranial magnetic stimulation (MEPs; corticospinal excitability) (STUDY #2; n = 17). MEP/TMEP ratios were further calculated to quantify changes in cortical excitability. RESULTS MVIC decreased at POST (P = 0.017) without any difference between VIBtendon and VIBmuscle, while RTD decreased for VIBtendon (P = 0.013) but not VIBmuscle. TMEP amplitudes were significantly decreased for all muscles (P = 0.014, P < 0.001 and P = 0.004 for VL, VM and RF, respectively) for both LV sites. While no changes were observed for MEP amplitude, MEP/TMEP ratios increased at POST for VM and RF muscles (P = 0.009 and P = 0.013, respectively) for both VIBtendon and VIBmuscle. CONCLUSION The present results suggest that prolonged muscle and tendon LV are similarly effective in modulating central nervous system excitability and decreasing maximal force. Yet, altered explosive performance after tendon but not muscle LV suggests greater neural alterations when tendons are vibrated.

Abstract
Background Neck pain is a prevalent pathological condition, and together with low back pain, it presents as the leading cause of years lived with disability worldwide in 2015 and continues to contribute substantially to the global burden of disease. Objective This study will investigate and compare the effects of stochastic resonance therapy (SRT), whole-body vibration (WBV), and balance training (BLT) in the management of chronic nonspecific neck pain. Methods In total, 45 participants with chronic neck pain will be randomly allocated into SRT, WBV, and BLT groups. Pain intensity, pressure pain threshold, neck disability, and cervical joint position sense will be measured before, immediately after, and 15 minutes after the first intervention session and after 4 weeks of intervention. A follow-up postintervention measurement would be taken after 4 weeks. The SRT group will train on an SRT device (SRT Zeptor Medical plus noise, Zeptoring). The WBV group will train on a Galileo vibration device (Novotec Medical), while the BLT group will perform balance exercises. All participants shall train 3 times a week for a period of 4 weeks. Mixed ANOVA will be used to determine the main and effects of interactions within (before intervention, post intervention 1, post intervention 2, post intervention 3, and follow-up) and between (SRT, WBV, and BLT) factors on the study outcome variables. Results Recruitment of participants started in May 2021, and as of May 2022, a total of 20 patients have been enrolled in the study. All participants are expected to have completed the trial by the end of 2022, and data analysis will commence thereafter. Conclusions The outcome of this study will shed closer light on the effects of SRT, WBV, and BLT on pain and function in patients with chronic neck pain.

Abstract
Whole-body vibration training (WBVT) offers a potential auxiliary treatment method for the rehabilitation of motor disabilities to address a reduction in bone minerals and lean mass caused by motor-disability rehabilitation. The aim of this review was to analyze the efficacy of WBVT in muscle-bone rehabilitation. In order to investigate the potential effect of WBVT on children and adolescents with motor disabilities, a meta-analysis was carried out. From January 2006 to June 2021, studies that met certain criteria were searched for in the Scopus, PubMed, Web of Science, and EBSCO databases. An analysis of standardized mean differences was performed using the STATA 15.1 software with a 95% confidence interval (PROSPERO registration number: CRD42021258538). Eight studies were selected that included 179 male and 139 female children and adolescents suffering from motor disabilities. The results of the meta-analysis showed that WBVT significantly improved femur bone-mineral density ((p < 0.01, z = 2.66), standardized mean difference (SMD) (95% CI) = 0.41 (0.11, 0.72)), total body-bone mineral content ((p < 0.01, z = 3.08), SMD (95% CI) = 0.26 (0.10, 0.43)), and lean mass ((p < 0.01, z = 2.63), SMD (95% CI) = 0.22 (0.06, 0.39)). In addition, there was no significant effect of WBVT on lumbar spine bone mineral density in the disabled children and adolescents ((p = 0.21, z = 1.25), SMD (95% CI) = 0.17 (-0.10, 0.43)). WBVT can improve femur bone density, total body bone mineral content, and lean mass in children and adolescents suffering from motor disabilities, while there is no effect on lumbar-spine bone density. WBVT can be used as a potential program to improve bone minerals in children and adolescents with motor disabilities.

Abstract
The purpose of this review is to examine how whole-body vibration can be used as a tool in therapy to help improve common physical weaknesses in balance, bone density, gait, spasticity, and strength experienced by individuals with cerebral palsy. Cerebral palsy is the most common movement disorder in children, and whole-body vibration is quickly becoming a potential therapeutic tool with some advantages compared to traditional therapies for individuals with movement disorders. The advantages of whole-body vibration include less strain and risk of injury, more passive training activity, and reduced time to complete an effective therapeutic session, all of which are appealing for populations with physiological impairments that cause physical weakness, including individuals with cerebral palsy. This review involves a brief overview of cerebral palsy, whole-body vibration's influence on physical performance measures, its influence on physical performance in individuals with cerebral palsy, and then discusses the future directions of whole-body vibration therapy in the cerebral palsy population.

Abstract
The results of three cases with infantile-onset Pompe disease participating in a rehabilitation program with home-based vibration training will be presented. In this retrospective observational case study, the cases participated in the neuromuscular training program "Auf die Beine", which combines two blocks of intensive, goal directed training with 6 months of home-based whole body vibration (WBV). Assessments by the means of a dual-energy X-ray absorptiometry and grip strength were applied at multiple points throughout the program. Two cases showed an increase in lean mass index of +0.319 kg/m2, +0.721 kg/m2 and bone mineral content of +0.028 kg/m2, +0.031 kg/m2 over one year. Additionally physiotherapeutic therapy goals could be achieved. In the remaining child lean mass index did not change, bone mineral content decreased by -0.03 kg. The neuromuscular rehabilitation program "Auf die Beine" has shown to be safe and effective in two of three cases for muscle and bone mass gain as well as in achievement of physiotherapeutic goals. To summarize, WBV is an innovative therapy in a rehabilitation concept, which might be helpful in Pompe disease, but further studies with larger cohorts are needed.

Abstract
The nuclear envelope and nucleoskeleton are emerging as signaling centers that regulate how physical information from the extracellular matrix is biochemically transduced into the nucleus, affecting chromatin and controlling cell function. Bone is a mechanically driven tissue that relies on physical information to maintain its physiological function and structure. Disorder that present with musculoskeletal and cardiac symptoms, such as Emery-Dreifuss muscular dystrophies and progeria, correlate with mutations in nuclear envelope proteins including Linker of Nucleoskeleton and Cytoskeleton (LINC) complex, Lamin A/C, and emerin. However, the role of nuclear envelope mechanobiology on bone function remains underexplored. The mesenchymal stem cell (MSC) model is perhaps the most studied relationship between bone regulation and nuclear envelope function. MSCs maintain the musculoskeletal system by differentiating into multiple cell types including osteocytes and adipocytes, thus supporting the bone's ability to respond to mechanical challenge. In this review, we will focus on how MSC function is regulated by mechanical challenges both in vitro and in vivo within the context of bone function specifically focusing on integrin, β-catenin and YAP/TAZ signaling. The importance of the nuclear envelope will be explored within the context of musculoskeletal diseases related to nuclear envelope protein mutations and nuclear envelope regulation of signaling pathways relevant to bone mechanobiology in vitro and in vivo.

Abstract
PURPOSE To summarize the findings and evaluate the role of vibratory therapy in the rehabilitation of neurological diseases. METHODS We systematically research PubMed, Scopus, Embase, Physiotherapy Evidence Database (PEDro), Web of Science, and Cochrane library databases from the inception until November 2020. We included studies that compared whole-body vibration (WBV) or focal muscle vibration (FMV) with placebo, sham, or another form of exercise in neurological disease rehabilitation in children and adults that result in motor impairments and disability. RESULTS We included 16 systematic reviews with good methodological quality evaluated using the Joanna Briggs Institute Umbrella Review Assessment and Review of Information appraisal tool. In stroke patients, WBV appears to play a role in improving gait and balance, while FMV is more effective in reducing spasticity. In multiple sclerosis and cerebral palsy, no evidence suggested that vibration therapy increases some patient outcomes. CONCLUSION WBV and FMV appear to play a considerable role in reducing spasticity and improving gait, balance, and motor function in stroke patients. By contrast, vibration therapy seems to be unable to reduce spasticity in multiple sclerosis and cerebral palsy. Also, correct use parameters for this therapy could not be defined.IMPLICATIONS FOR REHABILITATIONBased on the growing number of systematic reviews, this umbrella review aimed to summarize the findings and evaluate the role of vibration therapy in the rehabilitation of neurological diseases.Whole-body vibration and focal muscle vibration appear to play a considerable role in reducing spasticity and improving gait, balance, and motor function in patients affected by stroke.Focal muscle vibration appears to be more useful if applied to non-spastic antagonist muscles with reciprocal inhibitory action on spastic muscles in subjects affected by stroke.Vibration therapy seems not to be able to reduce spasticity in multiple sclerosis and cerebral palsy.

Abstract
AIM To identify and map studies that have assessed the effect of interventions on lower-limb macroscopic muscle-tendon morphology in children with spastic cerebral palsy (CP). METHOD We conducted a literature search of studies that included pre- and post-treatment measurements of lower-limb macroscopic muscle-tendon morphology in children with spastic CP. Study quality was evaluated and significant intervention effects and effect sizes were extracted. RESULTS Twenty-eight articles were identified. They covered seven different interventions including stretching, botulinum neurotoxin A (BoNT-A), strengthening, electrical stimulation, whole-body vibration, balance training, and orthopaedic surgery. Study quality ranged from poor (14 out of 28 studies) to good (2 out of 28). Study samples were small (n=4-32) and studies were variable regarding which muscles and macroscopic morphological parameters were assessed. Inconsistent effects after intervention (thickness and cross-sectional area for strengthening, volume for BoNT-A), no effect (belly length for stretching), and small effect sizes were reported. INTERPRETATION Intervention studies reporting macroscopic muscle-tendon remodelling after interventions are limited and heterogeneous, making it difficult to generalize results. Studies that include control groups and standardized assessment protocols are needed to improve study quality and data synthesis. Lack or inconclusive effects at the macroscopic level could indicate that the effects of interventions should also be evaluated at the microscopic level. WHAT THIS PAPER ADDS Muscle-targeted interventions to remodel muscle morphology are not well understood. Studies reporting macroscopic muscle remodelling following interventions are limited and heterogeneous. Passive stretching may preserve but does not increase muscle length. The effects of isolated botulinum neurotoxin A injections on muscle volume are inconsistent. Isolated strengthening shows no consistent increase in muscle volume or thickness.

Abstract
OBJECTIVE This study aimed to analyze the social-emotional behaviors of Chinese toddlers with cerebral palsy and to identify the risk factors associated with these behaviors. METHODS A total of 300 Chinese toddlers and their parents were recruited in this study. A Chinese version of the Infant-Toddler Social-Emotional Assessment was used to assess the children and basic information and clinical data were collected using an author-designed questionnaire. The patients were also assessed using a coping style questionnaire and the hospital anxiety and depression scale. Multiple logistic regression analysis was performed to identify risk factors. RESULTS The scores of the externalizing and competence domains for Chinese toddlers with cerebral palsy at different ages were lower compared to healthy children of the same age and gender (p<0.05). For the boys with cerebral palsy aged between 12-17 and 18-23 months, the scores of the internalizing and dysregulation domains were significantly lower compared to the national normal (p<0.01). The effect of perinatal factors on the externalizing and competence domains was more significant compared to other domains, whilst the coping style of the parents significantly affected the dysregulation domain (p=0.001). Multivariate analysis showed that the parental emotional state, education level, coping style and perinatal factors were closely associated with the social-emotional problems of children with cerebral palsy. CONCLUSION Children with cerebral palsy are more likely to have behavioral, emotional, and psychiatric issues that are mostly ignored. These children may benefit from early screening and intervention for risk factors to improve rehabilitation and long-term prognosis.

Abstract
Background Cerebral palsy (CP) is the most common cause of physical disability in early childhood. Vibration therapy (VT) is a promising rehabilitation approach for children with CP with potential to impact mobility, bone and muscle health as demonstrated by extant research. However, it is still unclear how long therapy must be conducted for and what the optimal vibration frequency is in order to gain health benefits. Methods/design The study is a randomized clinical trial evaluating and comparing the effects of two vibration frequency (20 Hz vs 25 Hz) and duration protocols (12 weeks vs 20 weeks) of side-alternating VT on mobility and other health parameters in children with CP. Children aged 5–12 years old with CP and GMFCS level I-III who are able to understand instruction and safely stand are eligible for the study. Exclusion criteria include bone fracture within 12 weeks of enrolment; acute conditions; the history of significant organic disease; the history of taking anabolic agents, glucocorticoids, growth hormone, and botulinum toxin injection into lower limbs within 3 months of enrolment. All participants will act as their own control with a 12-week lead-in period prior to intervention. The intervention period will consist of 20 weeks of home- or school-based VT 9 min per day, 4 times a week. After the baseline assessment, participants will be randomized to either a 20 Hz or 25 Hz vibration-frequency group. The primary outcome is mobility measured by a 6-min walking test, with analysis performed on the principle of intention to treat. Secondary outcomes include body composition, muscle strength, physical activity level, balance, gross motor function, respiratory function, and quality of life. Participants will undergo four assessment visits over the study period: baseline, at weeks 12, 24, and 32. Discussion The results of the study will provide evidence-based insights into the health benefits of side-alternating VT as a therapeutic tool in young children with cerebral palsy. The investigation of different vibration training protocols will help define the optimal parameters of intervention protocols (duration, frequency) of side-alternating VT to maximize outcomes on the health of 5–12-year-old children with CP.

Abstract
Background Sarcopenia, a progressive loss of muscle mass and function with advancing age, is a prevalent condition among older adults. As most older people are too frail to do intensive exercise and vibration therapy has low risk and ease of participation, it may be more readily accepted by elderly individuals. However, it remains unclear whether vibration therapy would be effective among older adults with sarcopenia. This systematic review and meta-analysis examined the effect of vibration therapy including local vibration therapy and whole-body vibration therapy, for enhancing muscle mass, muscle strength and physical function in older people with sarcopenia. Methods A systematic literature search was conducted in March 2019 in the following 5 electronic databases: PubMed, CINAHL, Embase, PEDro, and the Cochrane Central Register of Controlled Trials, with no restriction of language or the year of publication. Randomized controlled trials and quasi-experimental studies examining effects of vibration therapy on muscle mass, muscle strength or physical function in older adults with sarcopenia were included in this systematic review. Two reviewers independently assessed the methodological quality of the selected studies. Results Of the 1972 identified studies, seven publications from six studies involving 223 participants were included in this systematic review. Five of them conducted whole-body vibration therapy, while two conducted local vibration therapy. A meta-analysis of randomized controlled studies indicated that muscle strength significantly increased after whole-body vibration therapy (SMD 0.69, 95% CI 0.28 to 1.11, I2 = 0%, P = 0.001) and local vibration therapy (SMD 3.78, 95% CI 2.29 to 5.28, P < 0.001). Physical performance measured by the sit-to-stand test and the timed-up-and-go test were significantly improved after the intervention (SMD -0.79, 95% CI − 1.21 to − 0.37, I2 = 0%, P < 0.001) and SMD -0.83, 95% CI − 1.56 to − 0.11, I2 = 64%, P = 0.02, respectively). Conclusion Vibration therapy could be a prospective strategy for improving muscle strength and physical performance in older adults with sarcopenia. However, due to the limited number of the included studies, caution is needed when interpreting these results. More well-designed, large sample size studies should be conducted to further explore and validate the benefits of vibration therapy for this population.

Abstract
Objective To investigate the effect of age and Gross Motor Function Classification System (GMFCS) level on walking endurance after 20 weeks of vibration therapy in children and young people with cerebral palsy (CP). Design The study was a clinical trial without control group comparing baseline and postintervention outcomes within participants. Setting Vibration therapy was performed at school or at home. Assessments took place in a clinical research unit. Participants Children and young people (N=59) with CP, aged 5-20 years, GMFCS level II, III, or IV, recruited through schools, physiotherapy services, and District Health Board clinics, Auckland, New Zealand. Interventions Participants performed side-alternating whole-body vibration therapy (WBVT) at 20 Hz and 3-mm amplitude, 9 minutes per day, 4 times per week for 20 weeks. Main Outcome Measures Distance walked in the 6-minute walk test (6MWT) was recorded before and after the intervention. Results Participants baseline results for the 6MWT were lower, independent of age or GMFCS, when compared to non-CP literature. On average, participants walked 12% further in the 6MWT after the intervention (P<.001). There was significant improvement in 6MWT distance in all age groups (5-10y: 16%, P<.001; 11-15y: 10%, P=.001; 16-20y: 13%, P<.001) and all GMFCS levels (level II: 10%, P<.001, level III: 40%, P=.013, level IV: 57%, P=.007). There was a greater percentage improvement in the distance walked in those with GMFCS level III and level IV than level II (P=.049 and P<.001, respectively). Conclusions WBVT had a beneficial effect on walking endurance in children and young people with CP, independent of age and GMFCS.

Abstract
PURPOSE OF REVIEW Cerebral palsy is the most common physical disability of childhood, but the rate is falling, and severity is lessening. We conducted a systematic overview of best available evidence (2012-2019), appraising evidence using GRADE and the Evidence Alert Traffic Light System and then aggregated the new findings with our previous 2013 findings. This article summarizes the best available evidence interventions for preventing and managing cerebral palsy in 2019. RECENT FINDINGS Effective prevention strategies include antenatal corticosteroids, magnesium sulfate, caffeine, and neonatal hypothermia. Effective allied health interventions include acceptance and commitment therapy, action observations, bimanual training, casting, constraint-induced movement therapy, environmental enrichment, fitness training, goal-directed training, hippotherapy, home programs, literacy interventions, mobility training, oral sensorimotor, oral sensorimotor plus electrical stimulation, pressure care, stepping stones triple P, strength training, task-specific training, treadmill training, partial body weight support treadmill training, and weight-bearing. Effective medical and surgical interventions include anti-convulsants, bisphosphonates, botulinum toxin, botulinum toxin plus occupational therapy, botulinum toxin plus casting, diazepam, dentistry, hip surveillance, intrathecal baclofen, scoliosis correction, selective dorsal rhizotomy, and umbilical cord blood cell therapy. We have provided guidance about what works and what does not to inform decision-making, and highlighted areas for more research.

Abstract
Vibroacoustic therapy (VAT) is a treatment method that uses sinusoidal low-frequency sound and music. The purpose of this narrative review is to describe the effects of VAT on motor function in people with spastic cerebral palsy (CP) according to study design as well as providing information about the age of the participants, measurement tools, and sound frequencies that were used. The systematic search strategy based on the first two steps of a standard evidence-based approach were used: (1) formulation of a search question and (2) structured documented search including assessment of the relevance of abstracts and full texts to the search question and inclusion criteria. Out of 823 results of the search in 13 scholarly databases and 2 grey literature sources, 7 papers were relevant. Most of the relevant studies in children and adults presented significant improvement of motor function. According to the study design, only five experimental studies and two randomized controlled trial (RCT) studies were available. In the discussion, findings of this review are compared to other related methods that use mechanical vibrations without music. The authors recommend continuing to research the effects of VAT on motor function and spasticity in adolescents and young adults with spastic CP.

Abstract
Mesenchymal stem cells (MSC) rely on their ability to integrate physical and spatial signals at load bearing sites to replace and renew musculoskeletal tissues. Designed to mimic unloading experienced during spaceflight, preclinical unloading and simulated microgravity models show that alteration of gravitational loading limits proliferative activity of stem cells. Emerging evidence indicates that this loss of proliferation may be linked to loss of cellular cytoskeleton and contractility. Low intensity vibration (LIV) is an exercise mimetic that promotes proliferation and differentiation of MSCs by enhancing cell structure. Here, we asked whether application of LIV could restore the reduced proliferative capacity seen in MSCs that are subjected to simulated microgravity. We found that simulated microgravity (sMG) decreased cell proliferation and simultaneously compromised cell structure. These changes included increased nuclear height, disorganized apical F-actin structure, reduced expression, and protein levels of nuclear lamina elements LaminA/C LaminB1 as well as linker of nucleoskeleton and cytoskeleton (LINC) complex elements Sun-2 and Nesprin-2. Application of LIV restored cell proliferation and nuclear proteins LaminA/C and Sun-2. An intact LINC function was required for LIV effect; disabling LINC functionality via co-depletion of Sun-1, and Sun-2 prevented rescue of cell proliferation by LIV. Our findings show that sMG alters nuclear structure and leads to decreased cell proliferation, but does not diminish LINC complex mediated mechanosensitivity, suggesting LIV as a potential candidate to combat sMG-induced proliferation loss.
