Abstract Sarcopenia is a pathology resulting from a progressive and severe loss of muscle mass, strength, and function in the course of aging, which has deleterious consequences on quality of life. Among the most widespread studies on the issue are those focused on the effect of different types of physical exercise on patients with sarcopenia. This randomized controlled study aimed to compare the effects of a whole-body vibration exercise (WBV) session on the inflammatory parameters of non-sarcopenic (NSG, n=22) and sarcopenic elderly (SG, n=22). NSG and SG participants were randomly divided into two protocols: intervention (squat with WBV) and control (squat without WBV). After a one-week washout period, participants switched protocols, so that everyone performed both protocols. Body composition was assessed by dual-energy radiological absorptiometry (DXA) and function through the six-minute walk test (6MWD) and Short Physical Performance Battery (SPPB). Plasma soluble tumor necrosis factor receptors (sTNFR) were determined by enzyme-linked immunosorbent assay (ELISA) and measured before and immediately after each protocol. After exercise with WBV, there was an increase in sTNFR2 levels in the NSG (P<0.01; d=-0.69 (-1.30; -0.08) and SG (P<0.01, d=-0.95 (-1.57; -0.32) groups. In conclusion, an acute session of WBV influenced sTNFr2 levels, with sarcopenic individuals showing a greater effect. This suggested that WBV had a more pronounced impact on sTNFr2 in those with loss of muscle strength and/or physical performance. Additionally, WBV is gaining recognition as an efficient strategy for those with persistent health issues.

Objective:To explore the synchronization effect of whole-body vibration therapy combined with squat-up train-ing on ambulation of patients with stroke. Method:40 stroke survivors who could walk independently with supervision or assistive devices,were recruit-ed from the Department of Rehabilitation Medicine,Huashan Hospital Affiliated to Fudan University(Pudong Cam-pus)and were randomly divided into the WBVT group and the control group.Both groups received conven-tional rehabilitation treatment for 40 minutes per day.The WBVT group was given additional whole-body vibra-tion therapy while squat-up training for another 20 minutes a day.The control group added sham stimulation of standing on the vibration platform with no vibration for the same amount of time per day.At the begin-ning of enrollment and after 4 weeks intervention,participants received two times evaluation by the wearable three-dimensional gait assessment instrument for the function of walking,and the electromyographic signals of the rectus femoris and long head of the biceps femoris were collected by surface electromyography instrument and statistical analysis on the data before and after the intervention. Result:After 4 weeks intervention,the stride speed and stride length of both groups improved siginificanlty(P＜0.05),while the WBVT group was better than the control group(P＜0.05).The swing angle of knee(flex-ion or extention)in the WBVT group improved significantly after intervention compared with the control group.At the single leg support phase(SS)of affected side,the differences were found in the synergistic contraction rate of the rectus femoris and biceps femoris in the bilateral lower extremity of the WBVT group after the in-tervention(P＜0.05).At the swing phase(SW)of affected side,the differences were found in the synergistic contraction rate of the rectus femoris and biceps femoris in the bilateral lower extremity between the two groups before and after the intervention(P＜0.05),but the affected side of the WBVT group was better than that the control group after intervention(P＜0.05). Conclusion:Whole-body vibration therapy combined with rhythmic squat-up synchronous training can improve the stride speed,stride length and synergistic contraction rate of lower limb muscles for better ambulation of patients with stroke.

BACKGROUND:A large number of studies have investigated the effects of whole body vibration training at different frequencies on muscle strength,but less is reported on the differences in the efficacy of vibration training at different frequencies on patellar tendinopathy. OBJECTIVE:To explore the effect of eccentric training of quadriceps combined with different frequency of whole body vibration training on patellar tendinopathy. METHODS:From April to June 2022,48 patients with patellar tendinopathy were recruited from Wuhan Sports University and randomly divided into eccentric training group(n=12),30 Hz group(n=12),40 Hz group(n=12),and 50 Hz group(n=12).The eccentric training group only completed eccentric training of the quadriceps.The 30 Hz,40 Hz and 50 Hz groups performed the whole body vibration training with the amplitude of 2 mm and frequencies of 30 Hz,40 Hz and 50 Hz respectively on the basis of the eccentric training of the quadriceps.The intervention lasted for 8 weeks,three times a week.Before and after the intervention,the patients'surface electromyography signals of the quadriceps,kinematics and dynamics data of knee joint at the time of landing in deep jump and the time of peak vertical ground reaction,Visual Analogue Scale score,Victorian Institute of Sports Assessment-Patellar score were evaluated. RESULTS AND CONCLUSION:After 8 weeks of intervention,compared with the eccentric training group,the median frequency of the lateral and medial femoris muscles were significantly higher in the 40 Hz and 50 Hz groups(P＜0.05).At the time of landing,the knee joint flexion angle and external rotation moment in the 40 Hz and 50 Hz groups were significantly lower than those in the eccentric training group(P＜0.05),while the knee joint flexion angle in the 50 Hz group was significantly lower than that in the 30 Hz group(P＜0.05).At the peak moment of vertical ground reaction,the knee extension torque in the 40 Hz group was significantly lower than that in the eccectric training group(P＜0.05);the knee flexion angle and knee extension torque in the 50 Hz group were significantly lower than those in the eccentric training group(P＜0.05).The Visual Analogue Scale scores in the 50 Hz and 40 Hz groups were significantly lower than those in the eccentric training group(P＜0.05).The Victorian Institute of Sports Assessment-Patellar score in the 50 Hz group was significantly higher than that in the eccentric training group and 30 Hz group(P＜0.05).To conclude,eccentric training of the quadriceps combined with 50 Hz whole body vibration training can significantly improve quadriceps'strength,endurance and activation rate of the vastus lateralis muscle,reduce the pain of knee joint,and improve the function of the knee joint in patients with patellar tendinopathy.

BACKGROUND:Research on foot and ankle proprioception is crucial for the rehabilitation of chronic ankle instability and geriatric diseases as well as for the improvement of body posture control and motor performance.Previous studies have often studied the sensory evaluation of the foot and ankle joints separately,which has limitations for a comprehensive understanding of their sensory function. OBJECTIVE:The foot and ankle complex is the only part in direct contact with the support surface,and plays an important role in the collective sensory feedback and regulation and balance control.By combing the existing investigation and research of foot and ankle ontology,the measurement and evaluation methods of the sensation of the foot and ankle complex are combed,in order to pave the way and provide the theoretical basis for future related studies. METHODS:Chinese terms"(foot OR foot ankle OR ankle)AND(sensation OR proprioception)"and English terms"(foot OR ankle)AND(feel OR proprioception)"were used as the keywords for retrieving relevant literature in the Web of Science,PubMed,and CNKI.We understood the basic concepts,current status and scope of research on the foot and ankle,summarized and evaluated the proprioceptive evaluation methods of the foot and ankle,and finally included 57 papers for further review. RESULTS AND CONCLUSION:The evaluation of foot and ankle complex sensation was mainly divided into sensory evaluation of the foot and proprioceptive evaluation of the ankle joint.The sensory evaluation of the foot mainly describes the sensation of the skin and the sensory feedback under the intervention conditions.The methods mainly include the pressure sensory threshold test,the two-point discrimination test of the foot(planar and plantar),and the duration test of skin vibration sensation.Ankle joint proprioception evaluation focuses on the description of joint position,motion range,force value and functional performance.The methods are mainly divided into static joint angle reset test,motion minimum threshold test,force perception reproduction test and dynamic balance,speed and walking ability tests.The report of quantitative results is generally expressed by"an error,"which is generally divided into absolute error,relative error,constant error,etc.To conclude,the foot and ankle complex has specific sensory capabilities,including foot sensation and ankle proprioception,which affect the quality of life and athletic performance of humans.Weakness of both foot sensation and ankle proprioception is associated with reduced human balance,and the combined measurements of the two can comprehensively and effectively evaluate foot and ankle function.The combination of foot and ankle sensory measures is selected according to different research needs and various influencing factors such as environment,emotion and reporting style are fully considered,to improve the validity of measurement and evaluation.

BACKGROUND:Vibration environment can cause spinal injury,especially in patients with scoliosis.At present,there is no information about the inherent mode of the whole spine from T1 to the pelvis in scoliosis patients in the free state. OBJECTIVE:To analyze the dynamic characteristics of the whole spine in patients with scoliosis by the finite element method. METHODS:Based on CT scan images,a three-dimensional finite element model of the T1-pelvic total spine of an 11-year-old patient with thoracolumbar biflexion scoliosis was established,and the Cobb angles of thoracolumbar scoliosis were 36° and 24°,respectively.The mode analysis in the free state of the whole spine was carried out by the finite element method. RESULTS AND CONCLUSION:The fifteen-order free modes of the spine were extracted,and the dynamic characteristics of the scolio-curved spine were obtained.The resonance frequency distribution of the spine was concentrated.The thoracic vertebra was the most deformed in the whole spine model,and the amplitude of the thoracic vertebra was larger than that of the lumbar vertebra.Modal analysis was used to analyze the vibration characteristics of scoliosis patients in the vibration environment.It is of great significance to determine the natural frequency,vibration mode,and amplitude of scoliosis patients for analyzing the vibration characteristics of scoliosis.

BACKGROUND:Sarcopenia refers to age-related progressive,systemic muscle mass reduction and/or muscle strength decline or muscle physiological function decline,which is related to the occurrence of a variety of adverse outcomes in older adults.Exercise is considered to be one of the main strategies for combating sarcopenia in older adults,but there is a lack of specific intervention methods of different exercise patterns to intervene in sarcopenia. OBJECTIVE:To elaborate the main influencing factors of sarcopenia and the research progress of different exercise methods to improve sarcopenia in older adults,providing reference and basis for combating sarcopenia in older adults. METHODS:Web of Science,PubMed,CNKI,VIP,WanFang databases were retrieved for relevant literature published from January 2000 to October 2023 using the keywords of"sarcopenia,sport,exercise intervention,resistant training,aerobic exercise,whole body vibration training,mixed training,physical performance,muscle strength,muscle mass"in Chinese and English,respectively.A total of 126 articles were included for review. RESULTS AND CONCLUSION:Resistance exercise is still the most effective way to prevent and treat senile sarcopenia,and the effect of high-intensity resistance exercise is more significant.However,in practical application,we should pay attention to the gradual increase of training load intensity.Aerobic exercise combined with resistance exercise is more effective to improve muscle mass and function in the elderly than a single exercise mode.It is suggested that older adults can carry out the transition of low-intensity aerobic exercise in the early stage and increase resistance exercise individually in the late stage.Whole body vibration training is a new treatment method for the prevention and treatment of senile sarcopenia,but particular attention should be paid to the effects of frequency,amplitude,and duration on patients during practical application.Multicomponent exercise combines different exercise modes,which can give full play to their respective advantages,so as to personalize exercise interventions.

Objective:To observe any effect of cooling on the amplitude of vibration-induced sensory nerve action potentials (SNAPs) in human digits.Methods:The middle fingers of 15 healthy adults were either cooled to about 22℃ using an ice pack or kept at about 32℃. A vibrator was applied to the joint connecting the middle finger and the palm vibrating with an amplitude of 2mm at a frequency of 60Hz. The amplitudes of middle finger SNAPs before, during and right after the vibration were recorded.Results:The SNAP amplitude at a given temperature was lower during vibration than before it, but it immediately returned to the pre-vibration level after the vibration ceased. The middle finger SNAP amplitudes at 22℃ were significantly higher than those at 32℃ throughout. The decrease in amplitude at 32℃ (61.7±15.1%) was significantly greater than that at 22℃ (24.1±7.0%).Conclusions:Cooling significantly reduces the effect of vibration on the amplitude of digital SNAPs. That suggests a way to protect the sensory nerves in hand-arm vibration syndrome.

Background Vascular endothelial injury is an important pathogenic step of vibration-induced hand arm vibration disease (HAVD), and long-term vibration exposure can lead to vascular endothelial cell dysfunction and cell damage. Cell ferroptosis may be one of the important mechanisms of vibration-induced vascular endothelial cell injury and HAVD. Objective To explore whether vibration can induce changes in ferroptosis-related indicators in vascular endothelial cells in vitro. Methods Human umbilical vein endothelial cells (HUVEC) were divided into four vibrationgroups and two control groups. The vibration groups were exposed to an vibration setting of 125 Hz, 6.5 m·s−2 frequency band and for different durations: 1 d 2 h (total 1 d, 2 h per day), 1 d 4 h (total 1 d, 4 h per day), 2 d 2 h (total 2 d, 2 h per day), and 2 d 4 h (total 2 d, 4 h per day), respectively. All control groups were treated the same as the experimental groups except no vibration exposure. When the cells were 80% confluent, the control groups and the corresponding experimental groups were harvested at the same time. The effects of subgroup treatments on iron, reduced glutathione (GSH), and malondialdehyde (MDA) in HUVEC were detected with a cell ferrous colorimetric test kit, a reduced GSH colorimetric test kit, and a trace MDA test kit, respectively. Real-time quantitative polymerase chain reaction (RT-PCR) was used to detect the mRNA expressions of ferroptosis-related genes acyl-CoA synthetase long chain family member 4 (ACSL4), tumor protein 53 (P53), recombinant human ferritin heavy chain (FTH1), and glutathione peroxidase 4 (GPX4). Western blot (WB) was used to detect the expression levels of ferroptosis-related proteins in HUVEC. Results Compared with the control groups, the vibration induced an increase in the iron content of HUVEC with a dose-response trend. Compared with the control groups, the reduced GSH content of HUVEC in the vibration group decreased with the increase of vibration time and frequency, and there was a dose-response trend. Compared with the control groups, the intracellular MDA content of HUVEC in the 1 d 2 h, 1 d 4 h, and 2 d 4 h vibration groups increased, and the MDA content in the 1 d 2 h and 1 d 4 h vibration group increased with time. The RT-PCR results showed that the mRNA expression levels of ACSL4 and P53 in the 1 d 4 h group increased compared with the 1 d 2 h group. Compared with the 2 d control group, the mRNA expression levels of ACSL4 in the 2 d 2 h vibration group and the 2 d 4 h vibration group increased, and the mRNA expression level of P53 in the 2 d 4 h vibration group increased. Compared with the 1 d control group, the mRNA expression levels of FTH1 and GPX4 in endothelial cells in the vibration 1 d 2 h group decreased. The WB results showed that compared with the control groups, the expression level of ferroptosis-related protein ACSL4 in endothelial cells increased in the vibration 1 d 2 h group; the expression levels of P53 in the 1 d 2 h and 2 d 4 h vibration groups increased; the expression levels of GPX4 decreased in the 1 d 4 h and 2 d 2 h vibration group, and the decrease was more obvious in the 2 d 2 h vibration group than in the 1 d 2 h vibration group; the above differences were statistically significant (P<0.05). Conclusion Vibration induces an increase in iron content, a decrease in GSH, and an increase in MDA in vascular endothelial cells in vitro, as well as mRNA and protein expressions of ferroptosis-related genes ACSL4, P53, FTH1, and GPX4.

ObjectiveTo explore the effectiveness and safety of vibration-kneading abdominal tuina as an adjunct treatment for insomnia of phlegm-heat harassing the interior syndrome with "stomach disharmony" symptom. MethodsSeventy-six insomnia patients of phlegm-heat harassing the interior syndrome with "stomach disharmony" symptom were recruited， and randomly divided into the treatment group and the control group with 38 cases in each group. The control group received eszopiclone 2mg once a night and sleep hygiene guidance， while the treatment group received vibration-kneading abdominal tuina additionally， 5 times a week， 30 min each time. Both groups were treated for 4 weeks. The Pittsburgh Sleep Quality Index （PSQI） （including sleep quality， time to fall asleep， sleep duration， sleep efficiency， sleep disorders， daytime functioning scores， and total scores） and traditional Chinese medicine （TCM） symptom scores of "stomach disharmony" was assessed before and after 4-week treatment and at follow-up （12 weeks after treatment）. Adverse events were also observed and recorded during the study. Pearson correlation analysis was used to assess the correlation between the pre-treatment PQSI total score and TCM symptom score of "stomach disharmony". ResultsThe PSQI scores of sleep quality， time to fall asleep， sleep duration， sleep efficiency， sleep disorders， daytime dysfunction scores， and total scores reduced in both groups decreased after treatment and at follow-up （P＜0.05 or P＜0.01）， as well as the TCM symptom score of "stomach disharmony" （P＜0.01）. After treatment， the PSQI scores of sleep quality， sleep duration， and TCM symptom score of "stomach disharmony" of the treatment group were lower than those of the control group （P＜0.05 or P＜0.01）. At follow-up， the PSQI scores of sleep quality， sleep duration， sleep efficiency， daytime dysfunction score， total score， and TCM symptom score of "stomach disharmony" of the treatment group were lower than those of the control group （P＜0.05 or P＜0.01）. No adverse reactions occurred in any participants during the study. There was a positive correlation between the patients' pre-treatment PQSI total scores and TCM symptom score of "stomach disharmony" （r=0.88， P＜0.01）. ConclusionVibration-kneading abdominal tuina as an adjunct treatment could significantly improve the symptoms of stomach and epigastric symptoms in insomnia patients of phlegm-heat harassing the interior syndrome with "stomach disharmony" symptom， and improve the quality of sleep， with good immediate and long-term therapeutic effects， and sound safety.

ObjectiveTo explore the influencing factors of occupational hand-arm vibration disease (OHAVD) caused by handheld workpiece polishing. Methods A total of 222 OHAVD patients (case group), 275 hand-transmitted vibration-exposed workers (exposed group) and 243 healthy workers without hand-transmitted vibration exposure (control group) in a sports equipment manufacturing enterprise were selected as the study subjects using the convenience sampling method. Worksite survey of occupational health was conducted on these three groups, and the human vibration measurement equipment was used to measure the vibration exposure level of handheld vibration among the study subjects. The 8-hour energy equivalent frequency-weighted vibrating acceleration ［A(8)］ and cumulative vibration exposure level (CVEL) were calculated. Results The prevalence of coldness, numbness, tingling fingers, and vibration-induced white finger was higher in the exposed group and the case group compared with the control group (all P<0.05). The prevalence of the above-mentioned hand symptoms was higher in the case group compared with the exposed group (all P<0.05). The A(8) and CVEL levels of the study subjects in the case group were higher than those in the exposed group (all P<0.05). Binary logistic analysis result showed that age and CVEL were both influencing factors of OHAVD (all P<0.05). According to the restricted cubic spline models, CVEL of the study subjects in the exposed group had a positive nonlinear dose-response relationship with the risk of OHAVD (overall trend P<0.01, nonlinear P<0.01), indicating an increasing risk of OHAVD with increasing CVEL. Conclusion Hand-transmitted vibration exposure is a risk factor for OHAVD. Early intervention should be carried out for hand-transmitted vibration-exposed individuals to reduce vibration-exposed levels and control vibration exposure time.

Background The number of persons with thyroid nodules has increased rapidly in recent years, and thyroid cancer caused by malignant nodules has become a key problem endangering the health of young and middle-aged groups in China. Objective To explore work and lifestyle influencing factors for developing thyroid cancer among young and middle-aged patients with thyroid nodules. Methods The subjects with thyroid nodules were reported by routine physical examines ordered at the Huadong Sanatorium. We conducted a 1∶4 matched case-control study in which 232 patients diagnosed with thyroid cancer from 2012 to 2022 were matched to 928 controls by gender and age (±5 years). A validated questionnaire was used to collect data on work and lifestyle behaviors. Univariate and multivariate logistic regression models were applied to explore potential relationships between selected factors (including environment, working hours, stress, diet, exercise, and mental health) and thyroid cancer. Spearman rank correlation was used to analyze the correlations between variables. Results The results of univariate logistic regression showed a history of thyroid cancer reported among first-degree relatives (OR=6.059, 95%CI: 1.007, 36.473), obesity (OR=1.973, 95%CI: 1.296, 3.004), noise and vibration exposure (OR=1.988, 95%CI: 1.143, 3.456), frequent stress (OR=2.093, 95%CI: 1.231, 3.559), frequent depression (OR=2.034, 95%CI: 1.048, 3.947), frequent anger (OR=1.791, 95%CI: 1.066, 3.012), frequent fried food diet (OR=1.535, 95%CI: 1.026, 2.297), and frequent fast food diet (OR=1.836, 95%CI: 1.048, 3.215) were risk factors for reporting thyroid cancer developing from thyroid nodules, while regular meals (OR=0.245, 95%CI: 0.061, 0.989) and frequent exercise (OR=0.571, 95%CI: 0.342, 0.952) were protective factors for reporting no thyroid cancer. The results of Spearman correlation analysis showed that body mass index was positively correlated with frequent fried food, fast food, and sugary beverage diets (r=0.123, 0.083, 0.077, P<0.01), and negatively correlated with frequent depression and anger (r=−0.090, −0.070, P<0.05). The results of multiple logistic regression found that a history of thyroid cancer reported among first-degree relatives (OR=6.712, 95%CI: 1.071, 42.066), obesity (OR=2.032, 95%CI: 1.321, 3.125), noise and vibration exposure (OR=1.991, 95%CI: 1.089, 3.637), and frequent stress (OR=2.468, 95%CI: 1.417, 4.300) were associated with an elevated risk of reporting thyroid cancer developing from thyroid nodules patients. Regular exercise (frequency≥3 times·week−1, > 30 min per episode) (OR=0.516, 95%CI: 0.300, 0.890) was associated with a lowered risk of reporting thyroid cancer. Conclusions Multiple risk factors associated with reporting thyroid cancer among young and middle-aged groups with thyroid nodules are identified, such as obesity, noise and vibration exposure, frequent stress, and lack of exercise.

ABSTRACT Introduction: The research on vibration training has experienced a period of development in many projects, such as badminton, handball, long jump, and volleyball. However, there is still no quantitative research evaluation of its effects on the development of shoulder, elbow, and upper limb muscle strength in volleyball athletes. It is believed that a specific training protocol with vibration may bring benefits to sensory-motor performance and muscle strength implementation in volleyball athletes. Objective: To study the effects of vibration training on upper limb function in volleyball players. Methods: Literature, experimental, and mathematical-statistical research methods were used to explore the relationship between vibration training under the muscle strength of the upper limbs and their joints. Results: The vibration training with an amplitude of 2mm, at a vibration frequency between 30Hz and 45Hz, the frequency of vibration training presented inversely proportional to the effect of vibration training. Conclusion: Vibration training showed the benefits of motor coordination and increased muscle strength in volleyball players. An appropriate vibration training strategy can maximize athletes' skills, such as body coordination, flexibility, and jumping ability. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

摘要
ABSTRACT Introduction Vibration training refers to the introduction of vibration methods into the daily training of athletes for body stimulation. In this way, coaches improve athletes' strength, flexibility, and balance. Athletes can use vibration to stimulate neuromuscular activation. This allows more active units to be concentrated in the muscular contraction. In this way, the athlete's muscular strength can be increased. Objective This study aimed to analyze the relationship between vibration training and the balance ability of long jumpers. Methods This paper selects several long jumpers as research subjects. The effects of vibration exercises at different frequencies on athletes' stability are discussed, employing experimental comparison. In this context, statistical calculations are performed on the experimental results. Results There was no difference in balance ability between the vibration and general training groups before training (P>0.05). The athletes in the vibration training group showed more significant improvement in balance after a training period than the general training group. There were significant differences in the data between the two groups (P<0.01). Conclusion Vibration strength training can effectively improve the balance ability of jumpers. Athletes should increase the frequency of vibration training in their daily training. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
