BACKGROUND:There are increasing scientific and technological ways to promote the recovery of muscle fatigue after sports,such as vibrating foam shaft,fascia gun relaxation,and ultra-low temperature cold therapy.Fascia gun relaxation has been widely used in practice,but there is still relatively little research on fascial guns. OBJECTIVE:To compare the effects of three relaxation methods(fascia gun,stretching,fascia gun+stretching)on muscle status and muscle strength during the recovery of exercise-induced muscle fatigue,and to provide scientific basis for the application of the three methods in practice. METHODS:Forty college students were randomly divided into control group(n=10),stretching group(n=10),fascia gun group(n=10),and fascia gun+stretching group(n=10).All subjects completed leg flexion and extension training at 60%1 RM,15 times per set,for 10 sets in total,to make exercise fatigue models.After modeling,the subjects were intervened with supine rest,static stretching,fascia gun relaxation,fascia gun+stretching relaxation respectively.Muscle status and muscle strength indexes were tested before exercise,immediately after exercise,immediately after relaxation,24 and 48 hours after exercise. RESULTS AND CONCLUSION:The muscle tension and dynamic hardness of the control group and the stretching group immediately after relaxation were significantly higher than those before training(P<0.01).However,there was no significant difference in the fascia gun group and fascia gun+stretching group before and after training(P>0.05).At 24 hours after training,the peak torque of the control group and fascia gun group was significantly lower than that before training(P<0.01),and there was no significant difference in the stretching group and fascia gun+stretching group before and 24 hours after training(P>0.05).To conclude,the fascia gun can immediately and effectively improve the muscle state of sports fatigue and stretching can promote the effective recovery of muscle strength within 24 hours after sports fatigue.Relaxation using fascia gun plus stretching can achieve the superposition of the two effects.

BACKGROUND:Functional training has been popular in recent years,but it is mainly applied in sports training field.There are still insufficient studies and applications in medical and health fields. OBJECTIVE:To provide a theoretical basis for relevant research in sports,medical and health fields,through a more comprehensive and in-depth exploration and analysis of the research hot spots,ideological trends,frontiers and development trends of international functional training in the field of medical and health care. METHODS:The 2 206 high-quality articles addressing health-related functional training during 2012-2022 were exported from the Web of Science Core Set Database as the object of analysis.Combined with research methods such as literature analysis,Citespace V analysis software was used for visual analysis of keywords,subject categories and highly cited literatures. RESULTS AND CONCLUSION:The number of articles published on functional training in the field of health is on the rise.There are more articles from the United States,with a larger impact.China also has a high volume of publications,but the impact and depth of research is lacking.Improving physical and mental health and cognitive ability of middle-aged and older people is the main focus,followed by preventing sports injuries and promoting recovery in athletes.In the future,more research will be conducted on teenagers,the disabled and other groups,and there will be a continued increase in injury prevention and recovery promotion for athletes.Chinese scholars have less research on the effects of functional training on the physical health of the general public,and more attention should be paid to improving the physical and mental health of the general public.

OBJECTIVE:Some studies have shown that kinesio taping has positive effects in elevating muscle strength,improving joint stability and reducing pain and oedema in patients after anterior cruciate ligament reconstruction.However,existing studies have divergent results on the clinical efficacy of kinesio taping.In this study,a meta-analysis was conducted to systematically evaluate the effect of kinesio taping in postoperative rehabilitation period following anterior cruciate ligament reconstruction. METHODS:Randomized controlled trials about the effects of kinesio taping on anterior cruciate ligament reconstruction were electronically searched in PubMed,Web of Science,Embase,The Cochrane Library,EBSCO,CNKI,WanFang,and VIP databases,from database inception to December 06,2022.The outcome measures included six continuous variables:quadriceps strength,hamstring strength,knee swelling,knee range of motion,Lysholm knee function score,and Visual Analogue Scale score.EndNote X9.1 was used to screen the literature.The Cochrane Risk Bias Assessment Tool and Jadad Scale were used to evaluate the quality of the included literature.RevMan 5.3 software was used for Meta-analysis. RESULTS:A total of 6 randomized controlled trials involving 252 patients undergoing anterior cruciate ligament reconstruction were finally included.There were 126 cases in control group and 126 in kinesio taping group.The results of Meta-analysis showed that compared with the control group,kinesio taping significantly improved hamstring strength[standardized mean difference(SMD)=0.68,95%confidence interval(CI):0.12 to 1.23,P=0.02)and reduced Visual Analogue Scale score[mean difference(MD)=-0.56,95%CI:-1.04 to-0.08,P=0.02).However,for quadriceps strength,knee swelling,knee range of motion,and Lysholm knee function score,kinesio taping did not show significant difference from the control group(P＞0.05). CONCLUSION:Kinesio taping may help to improve hamstring strength and reduce pain in patients after anterior cruciate ligament reconstruction.However,it cannot significantly improve quadriceps strength,knee swelling,knee range of motion,and functional scores.

BACKGROUND:Previous studies have shown that knee joint moment changes in patients with knee osteoarthritis,but there are few reports on the correlation of moment changes with knee extensor muscle strength and gait spatiotemporal parameters. OBJECTIVE:To explore the correlation of knee extensor muscle strength and gait spatiotemporal parameters with peak knee flexion moment and knee adduction moment in female patients with knee osteoarthritis. METHODS:Twenty knee osteoarthritis female patients with single knee disease hospitalized in Guizhou Hospital,Beijing Jishuitan Hospital from February to August 2022 were selected as the knee osteoarthritis group,and an additional 20 healthy females without musculoskeletal disease were selected as the control group.The knee extensor force at 60(°)/s was measured with the Biodex isokinetic instrument.The gait spatiotemporal parameters and peak knee flexion moment and knee adduction moment were collected with the Italian BTS infrared motion capture system and force measuring platform.Pearson correlation analysis was used to explore the correlation of muscle strength and gait spatiotemporal parameters with peak knee adduction moment and knee flexion moment,and the variables significantly related to knee joint moment were further included in the multiple stepwise regression analysis. RESULTS AND CONCLUSION:(1)Compared with the control group,the knee osteoarthritis group had significantly lower knee extensor force,step speed,step frequency,step length,step width,peak knee adduction moment and knee flexion moment at 60(°)/s(P<0.05).(2)Pearson correlation analysis showed that the 60(°)/s centripetal extensor force,step speed,step frequency and step length were positively correlated with the peak knee flexion moment,and negatively correlated with the peak knee adduction moment,with a statistically significant difference(P<0.05).(3)The results of multiple stepwise regression showed that step speed and 60(°)/s knee extensor force were the strongest predictors of peak knee flexion moment,and the total R2 value of the two factors was 0.426,indicating that 42.6%of the total variance of this parameter could be explained.Step length and 60(°)/s centripetal extensor force were the strongest predictors of peak knee adduction moment.The total R2 value of the two factors was 0.602,indicating that 60.2%of the total variance of this parameter could be explained.(4)It is concluded that knee extensor strength,step speed and step length are the main variables affecting peak knee adduction moment and knee flexion moment.Therefore,these variables can be used for clinical gait monitoring and guidance to change knee joint load during knee osteoarthritis rehabilitation.

BACKGROUND:As we age,the function of various systems in the human body gradually decreases and the telomeres,located at the ends of chromosomes,consequently shorten,leading to the development and progression of various chronic age-related diseases.As a cost-effective intervention,scientific exercise has been shown to reduce the rate of telomere wear,maintain telomere length,delay the aging process and reduce the probability of disease.At the same time,better health level is important for healthy aging. OBJECTIVE:To sort out the role of telomeres in health promotion by analyzing telomere and physical fitness,the common adverse factors of telomere length shortening and chronic disease occurrence,and the influence of telomere length on the regulation of the occurrence and development of common chronic diseases such as cardiovascular disease,cancer,diabetes,obesity and mental disease,as well as to summarize the possible regulatory mechanism of exercise regulating telomere length,and to explore the role of telomere in the regulation of exercise on the above-mentioned chronic diseases for the purpose of health promotion. METHODS:The search terms of"exercise,telomere,aerobic capacity,muscle strength,aging"in Chinese and English were used to search the relevant literatures in CNKI and PubMed,respectively.A total of 108 articles were included for final review. RESULTS AND CONCLUSION:In terms of physical fitness and health promotion,there is a strong correlation between the maximum aerobic exercise capacity and muscle strength of the human body and telomere length.Long-term physical exercise can enhance the level of physical fitness to maintain telomere length and promote the heath of the human body.In terms of chronic diseases and health promotion,abnormal telomere length can promote the occurrence of some chronic diseases such as cardiovascular diseases,cancer,diabetes,obesity,and mental diseases,and the factors that accelerate the shortening of telomere length,such as oxidative stress,inflammation,and telomerase activity,also have adverse effects on the development of these diseases.The regulation of telomere length by exercise can reduce the levels of oxidative stress and inflammation,improve the activity of telomerase and enhance the stability of telomere protein complex.Through these regulatory mechanisms,exercise slows the rate of telomere wear and maintains consistent telomere length,thereby reducing the risk of chronic diseases associated with abnormal telomere length,such as cardiovascular disease,cancer,diabetes,obesity,and mental diseases.Therefore,telomeres play a positive role when exercise is used to regulate related diseases and promote human health.

OBJECTIVE:The effect of post-activation potentiation on sports performance is characterized by increased muscle mobility and increased rate of muscle force generation.In this paper,Meta-analysis is used to quantitatively evaluate the effects of post-activation potentiation on sprint speed,jumping performance,and kinetic parameters(peak impulse,peak power,maximum ground reaction force,rate of force generation,etc.)after activation of relative strength levels in the lower limbs. METHODS:Electronic databases such as CNKI,WanFang,Web of Science,PubMed,and Medline were retrieved for randomized control,random crossover,or clear grouping according to the relative strength levels of the lower limbs(non-randomized controls)on the post-activation potentiation effect after activation induced by the relative strength level of the lower limbs.Free weight equipment and rapid telescopic compound exercises were used as main intervention methods in each group.The publication time of the literature was from the inception of each database until August 5,2023.Endnote software was used to manage the literature.Literature quality assessment was conducted using the PEDro scale for randomized controlled trials and ROBINS-I 2.0 standards for non-randomized controlled trials.Revman5.4 and Stata15.0 software were used to conduct publication bias evaluation,subgroup analysis and sensitivity analysis of the extracted data,and forest plots were produced for Meta-analysis. RESULTS:Eleven documents(seven randomized controlled trials and four non-randomized controlled trials)were finally included,including 216 subjects.Overall,the methodological quality of the literature was high.According to the grouping standard of 1-repetition maximum/body mass>2 for the strong group and 1-repetition maximum/body mass≤2 for the normal group,there were 99 subjects in the strong group and 117 subjects in the normal group,all of whom were male.The positive effect of post-activation potentiation on sprint performance in the strong group was significantly higher than that in the normal group[standardized mean difference(SMD)=-1.34,95%confidence interval(CI):-1.74 to-0.93,P<0.000 01];the positive effect of post-activation potentiation on vertical jump height showed no significant difference between the strong and normal group(SMD=0.30,95%CI:-0.07 to 0.66,P=0.11);the positive effect of post-activation potentiation showed no significant difference between the strong and normal groups in terms of peak impulse(SMD=-0.07,95%CI:-0.62 to 0.47,P=0.61],peak power(SMD=0.21,95%CI:-0.29 to 0.72,P=0.12),maximum ground reaction force(SMD=0.31,95%CI:-0.20 to 0.81,P=0.16)and force generation rate(SMD=0.36,95%CI:-0.11 to 0.82,P=0.39). CONCLUSION:The post-activation potentiation effect in the strong group can significantly increase the short-distance sprint speed.The potentiation effect after activation of the relative strength level of the lower limbs has similar effects on the kinematic and kinetic parameters,including explosive vertical jump height,peak impulse,peak power,maximum ground reaction force and force generation rate.

OBJECTIVE:Cold water immersion methods are not standardized in terms of operational indicators such as immersion temperature,duration and depth,leading to controversy over the efficacy of recovery from exercise fatigue in skeletal muscle.In this article,we analyze the effects of cold water immersion on muscle injury,muscle soreness and muscle strength recovery under different factors,in order to find the best immersion implementation plan,and thus provide evidence for the recovery of muscle fatigue. METHODS:A search of CNKI,WanFang Data,Web of Science,and PubMed databases was conducted for relevant literature published from January 1,2000 to August 15,2023.A total of 4 759 articles were initially retrieved,with 4 735 articles excluded through screening and 24 articles finally included.The Physical Therapy Evidence Database Scale was used to assess the methodological quality of the included literature,and Stata-MP 16 software was used to perform effect size combinations,subgroup analyses,Meta-regression,sensitivity tests,and publication bias analyses. RESULTS:(1)The article included a total of 24 randomized controlled trial studies,including 617 subjects,with overall high legal quality.(2)Meta-analysis showed that cold water immersion can significantly reduce creatine kinase blood value[standardized mean difference(SMD)=-0.17,95％confidence interval(CI):-0.29 to-0.05,P<0.01],alleviate muscle pain(SMD=-0.60,95％CI:-0.81 to-0.38,P<0.01),and promote maximum muscle strength recovery(SMD=0.17,95％CI:0.05 to 0.30,P<0.01).(3)Subgroup analysis showed that:The immersing regimen with water temperature>14 ℃(SMD=-0.48,95％CI:-0.76 to-0.20,P<0.01)and duration of 12-14 minutes(SMD=-0.38,95％CI:-0.61 to-0.15,P<0.01)had the best effect in reducing creatine kinase blood values,and had a more significant intervention effect on endurance exercise(SMD=-0.45,95％CI:-0.71 to-0.20,P<0.01),while the immersion regimen with water temperature<10 ℃(SMD=-0.61,95％CI:-0.79 to-0.43,P<0.01),duration<12 minutes(SMD=-0.76,95％CI:-0.98 to-0.53,P<0.01),and immersion depth above the iliac spine(SMD=-0.74,95％CI:-0.97 to-0.52,P<0.01)had the best effect on relieving muscle soreness,and had a more significant analgesic effect after endurance exercise(SMD=-0.42,95％CI:-0.61 to-0.22,P<0.01).(4)Meta regression showed that immersion water temperature,immersion duration,and exercise type were important regulatory factors affecting the effect size of creatine kinase;immersing water temperature and immersing depth were important regulatory factors affecting the effect size of visual analogue scale score,while exercise type was an important regulatory factor affecting the maximum isometric muscle strength effect size. CONCLUSION:(1)Evidence of extremely low to moderate strength suggests that cold water immersion can effectively reduce muscle damage,alleviate muscle soreness,and promote muscle strength recovery.(2)In terms of reducing muscle injury,immersion water temperature,immersion duration,and exercise type are significant regulatory factors that affect the efficacy of immersing.Among them,immersion water temperature>14 ℃ and duration of 12-14 minutes are the best solutions to reduce muscle injury after exercise,and the immersing effect is better for endurance exercise.(3)In terms of reducing muscle soreness,immersion water temperature and immersion depth are important regulatory factors that affect the intervention effect.Among them,immersion water temperature<10 ℃,duration<12 minutes,and immersing depth above the iliac spine are the best solutions to reduce muscle soreness,and have a better analgesic effect after endurance exercise.(4)In terms of promoting muscle strength recovery,exercise type is a key regulatory factor that affects the maximum isometric muscle strength effect.

Objective:To investigate the correlation between serum sclerostin and sarcopenia-related indicators in chronic kidney disease (CKD) patients, and to find biomarkers and potential therapeutic targets that can take into account both osteoporosis and sarcopenia.Methods:It was a single-centre cross-sectional study. The clinical data of CKD stage 5 patients undergoing maintenance hemodialysis regularly and CKD stage 1-5 non-dialysis inpatients in the Hemodialysis Centre of Guangzhou Red Cross Hospital from March 2021 to March 2023 were collected retrospectively. The enzyme-linked immunosorbent assay was used to detect the level of serum sclerostin. The anthropometric data such as height, weight, upper arm circumference, upper arm muscle circumference, skinfold thickness, pinch strength and handgrip strength were measured. Body composition analyzer was used to measure the body composition. The patients were divided into CKD stage 1-3 group, CKD stage 4-5 group, and stage 5 hemodialysis group. One-way ANOVA, Kruskal-Wallis H test, and chi-square test were used to compare the differences of demographics and clinical characteristics in different stages of CKD. Spearman correlation analysis and multiple linear stepwise regression analysis were utilized to analyze the correlation between serum sclerostin and sarcopenia-related indicators in CKD patients. Results:The study included 104 patients with CKD stage 5 hemodialysis and 104 patients with CKD stage 1-5 non-dialysis patients, with age of (61.8±13.7) years old and 114 males (54.8%). There were 89 patients (42.8%) with diabetic nephropathy and 67 patients (32.2%) with sarcopenia. As renal injury progressed, serum sclerostin levels were 0.4 (0.3, 0.9) ng/L, 0.5 (0.3, 1.1) ng/L, and 1.1 (0.6, 2.3) ng/L in patients with CKD stage 1-3, stage 4-5, and stage 5 undergoing hemodialysis ( χ2=8.934, P<0.001), and the prevalence of sarcopenia was 16.4% (10/61), 34.9% (15/43), and 40.4% (42/104) ( χ2=10.312, P=0.006), respectively. Spearman correlation analysis showed that serum sclerostin was negatively correlated with estimated glomerular filtration rate ( r=-0.314, P<0.001), pinch strength ( r=-0.229, P=0.007), skinfold thickness ( r=-0.254, P<0.001), appendicular skeletal muscle index ( r=-0.169, P=0.010), body cell mass ( r=-0.174, P=0.020), and phase angle ( r=-0.264, P<0.001), and positively correlated with serum phosphorus ( r=0.227, P=0.002) and intact parathyroid hormone ( r=0.297, P<0.001). Multiple linear stepwise regression analysis showed that lg[appendicular skeletal muscle index] was negatively correlated with male ( β=0.330, t=5.675, P<0.001) and serum sclerostin ( β=-0.125, t=-2.143, P=0.033), and positively correlated with body mass index ( β=0.474, t=8.090, P<0.001). Conclusion:Serum sclerostin can be used as a good index and a potential therapeutic target for sarcopenia in CKD patients.

Purpose: This study aimed to investigate the effects of underwater walking for 6 weeks at 60% of the predicted maximum heart rate on respiratory muscle strength of elderly people as well as its sustained effects on respiratory muscle strength. Methods: The participants were 43 healthy elderly men, who were randomly divided into the continuous group (n=21) and the non-continuous group (n=22). Initially, both groups performed 30 min of underwater walking four times a week for 6 weeks, after which the continuous group continued the same for another 6 weeks, whereas the non-continuous group was prohibited from performing any exercise, except for daily activities. The walking speed during underwater walking was adjusted such that the exercise intensity was 60% of the predicted maximum heart rate, with the water depth up to the fourth intercostal space or higher. Outcome Measures: The maximal inspiratory pressure (PImax), maximal expiratory pressure (PEmax), and vital capacity (VC) were measured before exercise and 6, 8, 10, and 12 weeks after exercise. Results: The PImax and PEmax were significantly higher after 6 weeks of exercise than those before exercise. In the continuation group, PEmax increased significantly at 12 weeks of exercise compared to that at 6 weeks, whereas PImax did not show a significant increase. In the non-continuous group, PEmax decreased significantly from the 10th week onwards as compared to that at 6 weeks and showed a significantly lower value than that of the continuous group. The PImax of the non-continuous group decreased significantly at 12 weeks compared to that at 6 weeks. The VC after the 6-week underwater walking program did not differ from the pre-exercise value, with no significant difference observed between the two groups. Moreover, the VC in both groups showed no significant changes after 12 weeks of underwater walking compared to that after 6 weeks. Conclusions: Because underwater walking involves moving forward while resisting water pressure, it is necessary to activate the expiratory abdominal muscles to stabilize the trunk. Notably, the respiratory muscle strength in the non-continuous group decreased 4-6 weeks after the underwater walking program was terminated.

Objective:To investigate the improvement effect of acupuncture combined with early rehabilitation training on clinical efficacy, traditional Chinese medicine syndrome score, and neurological and motor functions of patients with acute cerebral infarction.Methods:A total of 76 patients with acute cerebral infarction who received treatment in the Department of Neurology at Jinhua Municipal Central Hospital from June 2019 to June 2022 were included in this prospective study. These patients were randomly divided into an observation group and a control group using the random number table method, with 38 patients in each group. The control group received early rehabilitation training, while the observation group received acupuncture combined with early rehabilitation training. The clinical efficacy was compared between the two groups. Pre- and post-treatment traditional Chinese medicine symptom scores and neurological and motor functions were compared between the two groups.Results:The overall response rate in the observation group was 89.47% (34/38), which was significantly higher than 67.59% (25/38) in the control group ( Z = 2.41, P = 0.016). After treatment, the scores of hemiplegia, mouth and eye deviation, and speech difficulty in both groups were significantly decreased compared with before treatment, and the observation group showed a greater degree of decline in these indices than the control group ( t = 4.73, P < 0.001; t = -10.58, P < 0.001; t = 6.42, P < 0.001). After treatment, the neurological deficit scale scores in each group were decreased compared with before treatment, and the observation group showed a greater degree of decline compared with the control group ( t = -7.33, P < 0.001). After treatment, the Fug-Meyer motor function scale and Barthel index scores in each group were significantly increased compared with before treatment, and the observation group showed a greater degree of increases compared with the control group ( t = 3.72, P < 0.001; t = -5.02, P < 0.001). After treatment, the bare hand muscle strength scores of the core muscles in both groups of patients were increased compared with before treatment, and the observation group showed a greater improvement compared with the control group ( t = 3.31, P < 0.001). Conclusion:Acupuncture combined with rehabilitation training can enhance clinical efficacy, improve traditional Chinese medicine syndrome scores, enhance neurological and motor functions, and strengthen core muscle strength in patients with acute cerebral infarction. This treatment approach is worthy of being further promoted in clinical practice.

At present, the major public health challenges caused by novel coronavirus infection have gradually subside. However, a large number of people are still suffering from long-novel coronavirus syndrome or post-novel coronavirus syndrome. The clinical manifestations of long coronavirus syndrome are related to multiple systems, such as respiratory, circulatory, nervous, digestive and musculoskeletal systems, with various long-term persistent symptoms after novel coronavirus infection. At the same time, the infection of the novel coronavirus is an important cause of frailty and sarcopenia in the elderly population. However, at present, the scholars have not paid enough attention to the skeletal muscle weakness caused by the novel coronavirus. Therefore, this paper focuses on the long-novel coronavirus syndrome and sarcopenia to explore the pathological mechanism of skeletal muscle attenuation caused by the SARS-CoV-2 mediated "cytokine storm", mitochondrial damage, hypoxia state and other links, so as to raise the attention of clinical and academic researchers and improve the clinical strategy of frailty and sarcopenia after novel coronavirus infection.

Objective:To investigate the effect of early pulmonary rehabilitation (PR) training on the improvement of respiratory function in patients with acute respiratory distress syndrome (ARDS) after weaning of invasive mechanical ventilation in the intensive care unit (ICU).Methods:The retrospective cohort research method was used. The clinical information of adult patients with ARDS receiving invasive mechanical ventilation admitted to the ICU of Qingdao Municipal Hospital from January 2019 to March 2023 was collected. The patients were divided into a control group and an observation group according to off-line training program. The control group received traditional training after weaning, and the observation group received the early PR training after weaning. Other treatments and nursing were implemented according to the routine of the ICU. The scores of the short physical performance battery (SPPB) on day 3-day 6 of the weaning training, respiratory muscle strength, level of interleukin-6 (IL-6), number of aspirations of sputum after weaning, length of stay after weaning, rehospitalization rate within 6 months after discharge, and pulmonary function indicators at discharge and 3 months after discharge [peak expiratory flow (PEF), forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC), and vital capacity (VC)] of the two groups of patients were compared. The Kaplan-Meier survival curve was drawn to analyze the cumulative survival rate of patients 6 months after discharge.Results:A total of 50 of which 25 cases received the traditional training after weaning, 25 cases received the early PR training after weaning. There was no significant difference in gender, age, acute physiology and chronic health evaluationⅡ (APACHEⅡ), oxygenation index upon admission, etiological diagnosis of ARDS upon admission, time of invasive ventilation, mode of invasive mechanical ventilation, pulmonary function indicators at discharge, and other baseline data of the two groups. The SPPB questionnaire scores and respiratory muscle strength in both groups were increased gradually with the extended offline training time, the serum level of IL-6 in both groups were descend gradually with the extended offline training time, especially in the observation group [SPPB questionnaire score in the observation group were 7.81±0.33, 8.72±0.53, 9.44±0.31, 10.57±0.50, while in the control group were 7.74±0.68, 8.73±0.37, 8.72±0.40, 9.33±0.26, effect of time: F = 192.532, P = 0.000, effect of intervention: F = 88.561, P = 0.000, interaction effect between intervention and time: F = 24.724, P = 0.000; respiratory muscle strength (mmHg, 1 mmHg≈0.133 kPa) in the observation group were 123.20±24.84, 137.00±26.47, 149.00±24.70, 155.40±29.37, while in the control group were 129.00±20.34, 126.00±24.01, 132.20±25.15, 138.60±36.67, effect of time: F = 5.926, P = 0.001, effect of intervention: F = 5.248, P = 0.031, interaction effect between intervention and time: F = 3.033, P = 0.043; serum level of IL-6 in the observation group were 80.05±6.81, 74.76±9.33, 63.66±10.19, 56.95±4.72, while in the control group were 80.18±7.21, 77.23±9.78, 71.79±10.40, 66.51±6.49, effect of time: F = 53.485, P = 0.000, effect of intervention: F = 22.942, P = 0.000, interaction effect between intervention and time: F = 3.266, P = 0.026]. Compared with the control group, the number of aspirations of sputum after weaning of patients in the observation group significantly decreased (number: 22.46±1.76 vs. 27.31±0.90), the length of ICU stay after weaning significantly became shorter (days: 6.93±0.95 vs. 8.52±2.21), and the rehospitalization rate within 6 months after discharge significantly decreased [20.00% (5/25) vs. 48.00% (12/25)]. There were significant differences. The pulmonary function indicators 3 months after discharge of two groups of patients significantly increased compared with those at discharge and those of the observation group were significantly higher than those of the control group [PEF (L/min): 430.20±95.18 vs. 370.00±108.44, FEV1/FVC ratio: 0.88±0.04 vs. 0.82±0.05, VC (L): 3.22±0.72 vs. 2.74±0.37, all P < 0.05]. The Kaplan-Meier survival curve showed that the cumulative survival rate of patients 6 months after discharge of patients in the observation group was significantly higher than that of patients in the control group [76.9% vs. 45.5%, hazard ratio ( HR) = 0.344, P = 0.017]. Conclusion:Early PR training can significantly improve the respiratory function of patients with ARDS after weaning of invasive mechanical ventilation. Continuous active respiratory training after discharge can improve the respiratory function of patients and effectively decrease mortality.

ObjectiveTo investigate the effect of the sling massage exercise on postpartum pelvic girdle pain (PPGP). MethodsFrom March, 2022 to May, 2023, 56 patients with PPGP in Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were randomly divided into control group (n = 28) and observation group (n = 28). Both groups received routine physical therapy and healthy education, while the control group received exercise therapy and the observation group received sling massage exercise, for six weeks. They were assessed with Visual Analog Scale (VAS), Pelvic Girdle Questionnaire (PGQ) and active straight leg raise (ASLR) test before and after treatment, and measured resting and contraction thickness of transversus abdominis with ultrasound; and integrated electromyography (iEMG), root mean square (RMS), median frequency (MF) and mean power frequency (MPF) of pelvic floor muscles with surface electromyography. ResultsAfter treatment, the total effective rate was 96.43% in the observation group and 78.57% in the control group (Z = 2.728, P < 0.05). All the indexes improved in both groups (|t| > 2.080, P < 0.05) except resting thickness of transverse abdominis muscle, and improved more in the observation group than in the control group (|t| > 2.161, P < 0.05). ConclusionThe sling massage exercise can alleviate pain, enhance the stability of the core muscle group, and improve load transfer and quality of life, better than exercise therapy.
