RESUMO
BACKGROUND: Cystic fibrosis is a chronic genetic disease that can affect the function of the respiratory system. Previous reviews of the effects of respiratory muscle training in people with cystic fibrosis are uncertain and do not consider the effect of age on disease progression. This systematic review aims to determine the effectiveness of respiratory muscle training in the clinical outcomes of children and adolescents with cystic fibrosis. METHODS: Up to July 2023, electronic databases and clinical trial registries were searched. Controlled clinical trials comparing respiratory muscle training with sham intervention or no intervention in children and adolescents with cystic fibrosis. The primary outcomes were respiratory muscle strength, respiratory muscle endurance, lung function, and cough. Secondary outcomes included exercise capacity, quality of life and adverse events. Two review authors independently extracted data and assessed study quality using the Cochrane Risk of Bias Tool 2. The certainty of the evidence was assessed according to the GRADE approach. Meta-analyses where possible; otherwise, take a qualitative approach. RESULTS: Six studies with a total of 151 participants met the inclusion criteria for this review. Two of the six included studies were published in abstract form only, limiting the available information. Four studies were parallel studies and two were cross-over designs. There were significant differences in the methods and quality of the methodology included in the studies. The pooled data showed no difference in respiratory muscle strength, lung function, and exercise capacity between the treatment and control groups. However, subgroup analyses suggest that inspiratory muscle training is beneficial in increasing maximal inspiratory pressure, and qualitative analyses suggest that respiratory muscle training may benefit respiratory muscle endurance without any adverse effects. CONCLUSIONS: This systematic review and meta-analysis indicate that although the level of evidence indicating the benefits of respiratory muscle training is low, its clinical significance suggests that we further study the methodological quality to determine the effectiveness of training. TRIAL REGISTRATION: The protocol for this review was recorded in the International Prospective Register of Systematic Reviews (PROSPERO) under registration number CRD42023441829.

BACKGROUND: The improvement of swallowing function after stroke is a significant challenge faced by patients and health care professionals. However, the current evidence synthesis of the effects of respiratory muscle training (RMT) on swallowing function is limited. OBJECTIVE: To assess the effectiveness of RMT on swallowing recovery in patients undergoing stroke. METHODS: The CKNI, WanFang Data, PubMed, CINAHL, Web of Science, Embase, MEDLINE, and Cochrane Library databases were searched for studies evaluating RMT interventions' effect on swallowing outcomes. Risks of bias were evaluated using the approach recommended by the Cochrane Collaboration tool and a summary of findings table was generated using the GRADE approach. Outcomes were synthesized using a random-effects meta-analysis model. RESULTS: RMT interventions reduced the risk of aspiration (SMD = 1.19; 95% CI, 0.53-1.84), the recovery process of water swallowing function (RR = 1.22; 95% CI, 1.05-1.42), and the activity of the swallowing muscles (SMD = 2.91; 95% CI, 2.22-3.61). However, there was no significant effect of RMT on the functional level of oral intake (SMD = 0.70; 95% CI, -0.03 to 1.42). CONCLUSIONS: RMT can be regarded as an innovative, auxiliary means in the near future to better manage and improve swallowing function, given its improving effect on work outcomes in this review.

OBJECTIVES: Patients with head and neck cancer (HNC) undergoing concurrent chemoradiotherapy (CCRT) often experience pulmonary symptoms. This study evaluated if a 7-week inspiratory muscle training (IMT) program during CCRT is feasible, adherent, and safe in patients with HNC. This study also evaluated the effect of IMT on diaphragm thickness, mobility, and cardiorespiratory parameters in patients with HNC receiving CCRT. METHODS: Ten participants with advanced stage HNC receiving CCRT were recruited for the study. Feasibility, adherence, and safety of the intervention were the primary outcomes. Changes in diaphragm thickness and mobility, maximal inspiratory pressure, maximal expiratory pressure, forced vital capacity, forced expiratory volume in first second and functional capacity using 6-MWT were measured at baseline and post 7 weeks of CCRT. IMT was performed at one session per day for 5 days a week for 7 weeks. Eight sets of two minutes of inspiratory manoeuvres with one minute rest period between them with intensity of 40% MIP were given. RESULTS: Ten participants were included in this study out of the 13 patients screened, indicating the feasibility to be 76.9%. Participants completed a total of 260 training sessions out of the 350 planned sessions denoting the adherence level as 74%. Diaphragm thickness and MEP remained significantly unchanged while significant decline was seen in diaphragm mobility, MIP,FVC, FEV1 and 6-MWD at the end of 7 weeks. No adverse events were reported following the intervention. CONCLUSION: Inspiratory muscle training did not show significant effect on the diaphragm thickness, mobility, and cardiorespiratory parameters; however, it was feasible, adherent, and safe in patients with HNC receiving CCRT.

OBJECTIVES: We aimed to identify the inspiratory muscle strength thresholds below which exercise capacity is compromised in men with chronic obstructive pulmonary disease (COPD). METHODS: We measured the maximum static inspiratory mouth pressure (PImax) and the percentage of predicted values (%PImax) in 113 patients with COPD. Six-minute walk distance (6-MWD) was measured as an indicator of functional exercise capacity, and a 6-MWD of <350 m was defined as functional exercise intolerance. Thresholds were determined as values with high specificity (>0.90) and maximal sensitivity. Statistical significance was set at P < 0.01. RESULTS: The data of 96 patients (74 ± 6 years old; forced expiratory volume in 1-s [FEV1], 56.5 ± 26.2% predicted) were analyzed; three women and 14 participants with missing data were excluded. Multivariate logistic regression models identified significant associations of PImax (odds ratio at 99% confidence interval [CI]: 0.95 [0.92-0.98]) and %PImax (odds ratio at 99% CI: 0.97 [0.95-0.99]) with 6-MWD, after adjustments for height and FEV1. C-statistics showed that the area under the curves (99% CI) of PImax and %PImax were comparable (0.87 [0.77-0.96] and 0.83 [0.72-0.94]). The thresholds of PImax and %PImax were 45.1 cmH2O and 66%; PImax and %PImax also had moderate positive likelihood ratios of 4.44 and 5.00. CONCLUSIONS: Thresholds of inspiratory muscle strength in men with COPD could help clinicians evaluate whether their patient's inspiratory muscle strength is inadequate to achieve a 6-MWD of ≥350 m, and identify patients who should be targeted for inspiratory muscle training.

BACKGROUND: In the literature, novel physiotherapy and rehabilitation approaches are getting significant attention as a way to cope with secondary complications in the management of asthma. OBJECTIVE: To investigate the effectiveness of core stabilization exercises combined with the Asthma Education Program (AEP) and breathing exercises in patients with asthma. METHODS: The study sample consists of 40 asthmatic patients (age 52.25 ± 11.51 years) who were randomly divided into a Training Group (TG) (n= 20) and a Control Group (CG) (n= 20). All subjects were included in the AEP, and both groups were trained in breathing retraining exercises (2 times/wk, 6-week duration in the clinic). The core stabilization exercise program was also applied in the TG. Respiratory muscle strength (maximum inspiratory and expiratory pressures), physical activity level (International Physical Activity Questionnaire Short Form (IPAQ)), health-related quality of life (Asthma Quality of Life Questionnaire (AQOL)), functional exercise capacity (six-minute walking test (6MWT)), and dynamic balance (Prokin PK200) were assessed before and after the interventions. RESULTS: The TG showed more significant improvements in MIP (ΔTG:4.55 cmH2O, ΔCG:0.95 cmH2O), IPAQ (ΔTG:334.15 MET-min/wk., ΔCG:99 MET-min/wk.), 6MWT (ΔTG:24.50 m, ΔCG:11.50 m), and dynamic balance sub-parameters compared to the mean difference between the initial assessment and after a 6-week intervention program, which included twelve exercise sessions (p< 0.01). CONCLUSIONS: The findings present greater improvements in inspiratory muscle strength, physical activity level, functional exercise capacity, and dynamic balance when core stabilization exercises are included in the pulmonary rehabilitation program for the management of asthma.

BACKGROUND: To the best of our knowledge, no studies have evaluated the effects of inspiratory muscle training (IMT) on recovered COVID-19 patients after weaning from mechanical ventilation. Therefore, this study assessed the efficacy of IMT on recovered COVID-19 patients following mechanical ventilation. METHODS: Forty-two recovered COVID-19 patients (33 men and 9 women) weaned from mechanical ventilation with a mean age of 48.05â±â8.85âyears were enrolled in this pilot control clinical study. Twenty-one patients were equipped to 2-week IMT (IMT group) and 21 matched peers were recruited as a control (control group). Forced vital capacity (FVC%), forced expiratory volume in 1 second (FEV1%), dyspnea severity index (DSI), quality of life (QOL), and six-minute walk test (6-MWT) were assessed initially before starting the study intervention and immediately after intervention. RESULTS: Significant interaction effects were observed in the IMT when compared to control group, FVC% (Fâ=â5.31, Pâ=â.041, ηP2â=â0.13), FEV1% (Fâ=â4.91, Pâ=â.043, ηP2â=â0.12), DSI (Fâ=â4.56, Pâ=â.032, ηP2â=â0.15), QOL (Fâ=â6.14, Pâ=â.021, ηP2â=â0.17), and 6-MWT (Fâ=â9.34, Pâ=â.028, ηP2â=â0.16). Within-group analysis showed a significant improvement in the IMT group (FVC%, Pâ=â.047, FEV1%, Pâ=â.039, DSI, Pâ=â.001, QOL, Pâ<â.001, and 6-MWT, Pâ<â.001), whereas the control group displayed nonsignificant changes (Pâ>â.05). CONCLUSIONS: A 2-week IMT improves pulmonary functions, dyspnea, functional performance, and QOL in recovered intensive care unit (ICU) COVID-19 patients after consecutive weaning from mechanical ventilation. IMT program should be encouraged in the COVID-19 management protocol, specifically with ICU patients.

OBJECTIVE: To evaluate the efficacy of an inspiratory muscle training protocol on inspiratory muscle function, functional capacity, and quality of life in patients with asthma. DESIGN: A single-blind, randomized controlled clinical trial. SETTING: Community-based. SUBJECTS: Patients with asthma, aged between 20 and 70 years old, non-smokers. INTERVENTIONS: Participants were randomized into two groups: inspiratory muscle training group performed inspiratory muscle training 5 days a week for 8 weeks, consisting of six sets of 30 breaths per day with a training load ⩾50% of maximal inspiratory pressure, plus an educational program; the control group only received the educational program. MAIN MEASUREMENTS: Maximal inspiratory pressure, inspiratory muscle endurance, and the distance performed on the incremental shuttle walking test were assessed pre-intervention, post-intervention and at follow-up (3 months after the end of the intervention). The asthma quality of life questionnaire was applied pre and post-intervention. RESULTS: Data from 39 participants were analyzed. Maximal inspiratory pressure in percentage of predicted and endurance test duration were significantly higher post-intervention in the inspiratory muscle training group (∆ post-pre: 50.8% vs 7.3% of predicted - P < 0.001 and ∆ post-pre: 207.9 seconds vs 2.7 seconds - P < 0.001, respectively). There was no significant difference in the incremental shuttle walking distance between groups (∆ post-pre: 30.9 m vs -8.1 m, P = 0.165). Quality of life was perceived as significantly better, without a difference between groups (P > 0.05). CONCLUSIONS: About 8 weeks of inspiratory muscle training in patients with controlled asthma significantly increased inspiratory muscle strength and endurance.

AIM: The aim of this study was to evaluate the effects of interval high intensity inspiratory muscle training (IMT) on resting breathing pattern in patients with advanced lung disease. METHODS: IMT was performed daily and training load set at 50 % of the maximal inspiratory pressure. Participants were evaluated at pre-IMT, post 8 weeks of IMT and follow-up (3 months after the end of IMT). Breathing pattern (volume and time variables as well as percentages of contribution to tidal volume) was evaluated by Optoelectronic Plethysmography at rest. Friedman test was used to verify the differences between the three time-points (p < 0.05). RESULTS: Nineteen patients (54 ± 16 years old; 5 males) were evaluated at pre-IMT and post-IMT and fourteen were assessed at follow-up. There was no significant difference (p > 0.05) in any comparison for all evaluated breathing pattern variables at the three time-points. CONCLUSION: Resting breathing pattern was not significantly changed after 8 weeks of IMT in patients with advanced lung disease.

OBJECTIVES: To compare the effects of Liuzijue Qigong and conventional respiratory training on trunk control ability and respiratory muscle functions in patients at an early recovery stage from stroke. DESIGN: A single-blind, randomized controlled trial. SETTING: A hospital. PARTICIPANTS: Patients (N=60) within 2 months poststroke. INTERVENTIONS: The experimental group (n=30) received conventional rehabilitation training combined with Liuzijue exercise, and the control group (n=30) received conventional rehabilitation training combined with conventional respiration training. The training in the 2 groups was conducted 5 times per week for 3 weeks. MAIN OUTCOME MEASURES: Trunk Impairment Scale (TIS), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), maximum expiratory mid-flow (MMEF), diaphragmatic movement, the change of intra-abdominal pressure (IAP), Berg Balance Scale (BBS), and Modified Barthel Index (MBI). All outcome measures were assessed twice (at baseline and 3 weeks). RESULTS: Both groups significantly improved in TIS, MIP, FVC, PEF, and the change of IAP, BBS, and MBI when pre- and postassessments (P<.05) were compared. Compared with the control group, there was a significant difference in the experimental group in the static sitting balance subscale (P=.014), dynamic balance subscale (P=.001), coordination subscale (P<.001), TIS total scores (P<.001; effect size [ES]=0.9), MIP (P=.012; 95% confidence interval [CI], 2.23-17.69; ES=0.67), MEP (P=.015; 95% CI, 1.85-16.57; ES=0.65), change of IAP (P=.001), and MBI (P=.016; 95% CI, 1.51-14.16; ES=0.64). No significant differences were found between the 2 groups in FEV1 (P=.24), FVC (P=.43), PEF (P=.202), MMEF (P=.277), the diaphragmatic movement of quiet breathing (P=.146), deep breathing (P=.102), and BBS (P=.124). CONCLUSIONS: Liuzijue exercise showed more changes than conventional respiratory training in improving trunk control ability, respiratory muscle functions, and activities of daily living ability in patients at an early recovery stage from stroke.

BACKGROUND: Circumferential burn of chest (CBC) is a significant type of burn and considers as a major cause of restrictive lung disease (RLD). Patient who has CBC with RLD leads to respiratory symptoms such as breathing difficulty, airway obstruction, reduced exercise capacity and altered pulmonary functions. However, studies examining the role of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full thickness circumferential burn of chest are lacking. OBJECTIVE: To find the short term effects of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full thickness circumferential burns of chest. METHODS: Through simple random sampling method thirty subjects (N = 30) with RLD following CBC were allocated to pranayama breathing exercise group (PBE-G; n = 15) and conventional breathing exercise group (CBE-G; n = 15). They received pranayama breathing exercise and conventional breathing exercise for 4 weeks respectively. All the subjects received chest mobility exercise as common treatment. Primary (Numeric Pain Rating Scale - NPRS, forced expiratory volume (FEV1), forced vital capacity (FVC) and maximum voluntary ventilation (MVV) and secondary (Electromyogram of sternocleidomastoid, scalene, external intercostal and diaphragm muscle, 6 min walk test & Global Rating of Change - GRC) outcome measures were measured at baseline, after four weeks and after three months follow up. RESULTS: Baseline demographic and clinical variables show homogenous distribution between the groups (p > 0.05). Four weeks following different breathing exercises, PBE-G group shows more significant changes in pain intensity, pulmonary function, respiratory muscle activity, exercise tolerance and global rating of change than CBE-G group (p ≤ 0.05) at four weeks and three months follow up. CONCLUSION: Both groups showed improvement over time. However, differences between the groups were noticed small. Still physiotherapy management, which included pranayama breathing exercises with chest mobilization program, had an effective strategy in the treatment of restrictive lung disease following circumferential burn of chest.

BACKGROUND: Aging results in a decline in the function of the respiratory muscles. Inspiratory muscle training is presented as a possible solution to attenuate the loss of respiratory function in the elderly. The objective of the study was to evaluate and compare the efficacy of 2 protocols with inspiratory muscle training (IMT), low loads and high loads, to improve respiratory strength, functional capacity and dyspnea in institutionalized elderly women, over 65 years. METHODS: The study was a controlled, randomized, double-blind trial and with allocation concealment performed on 26 institutionalized elderly women distributed in 2 groups, the high-intensity group (HIG) and low-intensity group (LIG). Over an 8-week period an IMT protocol was followed 5 days/week, 15 min/day. The HIG trained with a load of 40% of the maximum inspiratory pressure (MIP) and the LIG with 20%. MIP, maximum expiratory pressure (MEP), functional capacity and dyspnea were evaluated. RESULTS: After training, in the HIG MIP, MEP and functional capacity increased 52, 16 and 7%, respectively (p = 0.000, p = 0.001, p = 0.001) and in the LIG 30, 18 and 9%, respectively (p = 0.002, p = 0.014, p = 0.001). The improvement in MIP was significantly higher in the HIG than in the LIG (p = 0.042). CONCLUSION: IMT with low and high loads improves respiratory muscle strength and functional capacity in institutionalized elderly women. In addition, high loads were significantly more effective to improve MIP.

To address progressive respiratory muscle weakness in late-onset Pompe disease (LOPD), we developed a 12-week respiratory muscle training (RMT) program. In this exploratory, double-blind, randomized control trial, 22 adults with LOPD were randomized to RMT or sham-RMT. The primary outcome was maximum inspiratory pressure (MIP). Secondary and exploratory outcomes included maximum expiratory pressure (MEP), peak cough flow, diaphragm ultrasound, polysomnography, patient-reported outcomes, and measures of gross motor function. MIP increased 7.6 cmH2O (15.9) in the treatment group and 2.7 cmH2O (7.6) in the control group (Pâ¯=â¯0.4670). MEP increased 14.0 cmH2O (25.9) in the treatment group and 0.0 cmH2O (12.0) in the control group (Pâ¯=â¯0.1854). The only statistically significant differences in secondary/exploratory outcomes were improvements in time to climb 4 steps (Pâ¯=â¯0.0346) and daytime sleepiness (Pâ¯=â¯0.0160). The magnitude of changes in MIP and MEP in the treatment group were consistent with our pilot findings but did not achieve statistical significance in comparison to controls. Explanations for this include inadequate power and baseline differences in subject characteristics between groups. Additionally, control group subjects appeared to exhibit an active response to sham-RMT and therefore sham-RMT may not be an optimal control condition for RMT in LOPD.

BACKGROUND: Signs of respiratory dysfunction can be present already early in the course of Parkinson's disease (PD). Respiratory training could alleviate this, but its effectiveness is not well understood. OBJECTIVE: The purpose of this systematic review is to review the efficacy of different respiratory training interventions in PD. METHODS: A search strategy was performed in four databases: PubMed, Physiotherapy Evidence Database (PEDro), Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Methodological quality of original full-text articles was assessed using the Cochrane Risk of Bias tool for randomized controlled trials (RCTs) and the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool for the controlled trials (CTs). Levels of evidence were rated by the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. RESULTS: Six papers reporting on four randomized controlled trials and another four controlled trials were included. Positive effects were reported for inspiratory muscle strength training (IMST), expiratory muscle strength training (EMST), air stacking, breath-stacking, incentive spirometry and postural training on respiratory muscle strength, swallowing safety, phonatory aspects and chest wall volumes. Best methodological quality was found for breath-stacking and incentive spirometry. Best levels of evidence were found for EMST, IMST and EMST plus air stacking. CONCLUSION: Respiratory training shows positive effects and should be considered when people with PD experience respiratory dysfunction. Future studies should focus on standardizing both training devices, instruments to measure outcomes and intervention protocols to further increase the level of evidence.

OBJECTIVE: The purpose of this study was to compare pulmonary function and respiratory muscle strength and endurance in individuals with thoracic outlet syndrome (TOS) and healthy participants. METHODS: Sixty-two individuals with TOS (mean age 30.81 ± 10.69 years; 10 male, 52 female) and 47 healthy individuals (mean age 30.64 ± 9.16 years; 14 male, 33 female) participated in this study. Pulmonary function testing was performed using a spirometer. Respiratory muscle strength (maximal inspiratory pressure [MIP] and maximal expiratory pressure [MEP]) were measured using a mouth pressure device. Respiratory muscle endurance was tested at 35% MIP and measured as the time in seconds from the start of the test to voluntary exhaustion. RESULTS: Age distribution and physical characteristics were similar between the groups (P > .05). All pulmonary function parameters except for peak expiratory flow rate were similar in patients with TOS and healthy controls (P > .05). Patients with TOS had significantly lower peak expiratory flow rate, MIP, MIP%, MEP, MEP%, and respiratory muscle endurance compared with controls (P < .05). Forty-six patients with TOS (74.2%) had MIP values below the lower limit of the 95% CI of the control group (97.05-113.88 cmH2O), and 53 patients with TOS (85.2%) had MEP values below the lower limit of the 95% CI of the control group (124.74-146.49 cmH2O). CONCLUSION: Expiratory flow rate and respiratory muscle strength and endurance may be adversely affected in TOS. Trunk muscles perform both postural and breathing functions. Therefore, disruption in one function may negatively affect the other.

OBJECTIVE: To evaluate the effects of respiratory muscle training in a population of stroke patients. DATA SOURCES: The following databases were searched for clinical trials through December 2019: PubMed, EMBASE, Cochrane Library, CINAHL, and China National Knowledge Infrastructure. STUDY SELECTION: Randomized controlled trials (N=9) published in English met the inclusion criteria. DATA EXTRACTION: Data were extracted and assessed for accuracy by 2 reviewers. Any disagreements were resolved after discussions with an independent third reviewer. The quality of the included randomized controlled trials was assessed using the Cochrane bias tool. DATA SYNTHESIS: The meta-analysis showed increased maximal inspiratory pressure (standardized mean difference [SMD], 0.88; 95% confidence interval [CI], 0.62-1.15; P<.001; 12-wk follow-up period: SMD, 0.94; 95% CI, 0.42-1.45; P<.001), maximal expiratory pressure (SMD, 0.83; 95% CI, 0.15-1.52; P=.017; 12-wk follow-up period: SMD, 0.99; 95% CI, 0.47-1.51; P<.001), forced expiratory volume in 1 second (SMD, 1.41; 95% CI, 0.57-2.24; P=.001), forced vital capacity (SMD, 1.36; 95% CI, 0.55-2.16; P<.001), peak expiratory flow (SMD, 0.74; 95% CI, 0.16-1.32; P=.013), 6-minute walk test (SMD, 0.67; 95% CI, 0.11-1.23; P=.020), and decreased respiratory complications (odds ratio, 0.55; 95% CI, 0.30-1.00; P=.050) compared with no respiratory intervention or a sham intervention. CONCLUSIONS: Respiratory muscle training improved poststroke muscle strength and the benefits were carried over for up to 12 weeks, including improved lung function, walking capacity, and a reduced risk of respiratory impediments.

BACKGROUND: Chronic kidney disease (CKD) represents the irreversible stages of renal failure and is a growing worldwide public health issue associated with increases in morbidity, mortality, and decreased quality of life. Kidney transplantation is considered one of the best treatment options in this population. However, even after surgery, respiratory muscle strength is below normal values, and inspiratory muscle training (IMT) improves respiratory muscle function, strength, and endurance. This study aimed to evaluate the effects of IMT regarding respiratory muscle strength, functional capacity, and pulmonary function in pediatric kidney transplant recipients with CKD, and secondarily, to assess the biochemical profile of patients after intervention. METHODS: This is a randomized, double-blind, placebo-controlled trial. Patients were randomized into two groups, intervention (IG) and control (CG) and performed IMT home-based training for 6 weeks. In the IG, the load was adjusted to 40% of the maximal inspiratory pressure and in the CG was adjusted to a minimum placebo load (9 cm H2O). RESULTS: Thirty-one patients were randomly allocated to the intervention (n = 16) or control (n = 15) groups. There were no differences at baseline between groups. Increase of 35% in the maximal inspiratory pressure predicted and 26% in the maximal expiratory pressure predicted in the IG were found, compared with 5 and 4% in the CG. There was an increase in hemoglobin and hematocrit values in the IG. CONCLUSIONS: Home-based IMT provides a significant increase in respiratory muscle strength, without changes in functional capacity and pulmonary function. Benefits regarding biochemical markers (hemoglobin and hematocrit) were also observed.

BACKGROUND This study examined the effects of abdominal draw-in lumbar stabilization exercises (ADIM) with respiratory resistance on women ages 40-49 years with low back pain. MATERIAL AND METHODS Forty-four women ages 40-49 years were screened for participation and were randomly assigned to either a respiratory with resistance exercise group (n=22) or a control group (n=22). Abdominal draw-in lumbar stabilization exercises were administered to both groups, but only the respiratory with resistance exercise group received the respiratory resistance training. The exercise training lasted 50 min per session, 3 sessions per week for 4 weeks. The assessment methods used were the quadruple visual analogue scale (QVAS), Oswestry disability index-Korean version (ODI-K), diaphragm thickness and contraction rate, and lung capacity test. RESULTS Both groups showed significant differences in the QVAS, ODI-K, maximum voluntary ventilation (MVV), and diaphragm thickness and contraction rate before and after the intervention (p<0.05). In the respiratory resistance exercise group, the ODI-K, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), MVV, and diaphragm thickness and contraction rate showed significantly better improvement than the control group (p<0.05). CONCLUSIONS A lumbar stabilization exercise program consisting of ADIM and respiratory resistance resulted in decreased pain, reduced dysfunctions, and increased muscle thickness in contraction, contraction rate, and pulmonary function. Strong contraction of the diaphragm and deep abdominal muscles through breathing resistance increased the pressure in the abdominal cavity. Therefore, this may be an effective clinical exercise method for patients with lumbar instability.

OBJECTIVE: To investigate the pulmonary function responses to respiratory muscle training (RMT) in individuals with tetraplegia and provide a systematic review of the included studies. METHODS: Computerized retrieval of randomized controlled trials (RCT) in PubMed, Embase, and the Cochrane Library on the improvement of respiratory function in patients with spinal cord injury by RMT was conducted until May 2019. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Articles were scored for their methodological quality using the Cochrane Collaboration risk of bias assessment tool. RESULTS: Sixteen studies were identified. A significant benefit of RMT was revealed for five outcomes: force vital capacity (FVC, WMD: -0.43, 95% CI -0.84 to -0.03, P = 0.037), vital capacity (VC, WMD: -0.40, 95% CI -0.69 to -0.12, P = 0.037), vital capacity (VC, WMD: -0.40, 95% CI -0.69 to -0.12, P = 0.037), vital capacity (VC, WMD: -0.40, 95% CI -0.69 to -0.12, P = 0.037), vital capacity (VC, WMD: -0.40, 95% CI -0.69 to -0.12, P = 0.037), vital capacity (VC, WMD: -0.40, 95% CI -0.69 to -0.12. CONCLUSION: Our findings demonstrate that RMT can effectively improve spinal cord injury pulmonary function of the patient, which is marked by increasing respiratory strength, function, and endurance. Limited by the quantity and quality of the included studies, the above conclusion needs to be verified by more high-quality studies.

BACKGROUND: Respiratory muscle weakness is a primary cause of morbidity and mortality in patients with Pompe disease. We previously described the effects of our 12-week respiratory muscle training (RMT) regimen in 8 adults with late-onset Pompe disease [1] and 2 children with infantile-onset Pompe disease [2]. CASE REPORT: Here we describe repeat enrollment by one of the pediatric participants who completed a second 12-week RMT regimen after 7 months of detraining. We investigated the effects of two 12-week RMT regimens (RMT #1, RMT #2) using a single-participant A-B-A experimental design. Primary outcome measures were maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP). Effect sizes for changes in MIP and MEP were determined using Cohen's d statistic. Exploratory outcomes targeted motor function. RELEVANCE: From pretest to posttest, RMT #2 was associated with a 25% increase in MIP and a 22% increase in MEP, corresponding with very large effect sizes (d= 2.92 and d= 2.65, respectively). Following two 12-week RMT regimens over 16 months, MIP increased by 69% and MEP increased by 97%, corresponding with very large effect sizes (d= 3.57 and d= 5.10, respectively). MIP and MEP were largely stable over 7 months of detraining between regimens. Magnitude of change was greater for RMT #1 relative to RMT #2.
