Change in Pulmonary Function after Incentive Spirometer Exercise in Children with Spastic Cerebral Palsy: A Randomized Controlled Study

Assessments and exercises of cough strength in critically ill patients: a literature review

Background and Objective

Airway clearance is essential for maintaining patency in critically ill patients and relies on the mucociliary escalator, expiratory flow, and cough strength. A weak cough significantly increases the risk of therapy failure in patients receiving noninvasive ventilation (NIV) or high-flow nasal cannula (HFNC). This review aims to summarize current practices for assessing and exercising cough strength in critically ill patients.

Methods

A comprehensive literature search was conducted in PubMed, Embase, and ScienceDirect using specific keywords related to cough assessment and exercises. A total of 281 articles on cough assessment and 1,407 on cough exercises were identified, with 26 and 73 studies included in the review, respectively.

Key Content and Findings

By collecting literature related to cough efficacy, this narrative review describes methods for assessing cough ability and strategies for improving it. The assessment methods for cough ability include quantitative, semi-quantitative, and qualitative evaluations, each targeting different populations and having its own advantages and disadvantages. For patients whose cough ability has diminished, it is essential to implement cough training. Cough exercises focus on increasing inhaled volume, enhancing expiratory flow, and utilizing oscillation techniques to improve cough effectiveness. Choosing the appropriate training method for the patients can lead to significantly better outcomes.

Conclusions

Weak cough in critically ill patients correlates with increased risks of extubation failure and prolonged hospitalization. Employing appropriate assessment methods and individualized cough exercises is critical for improving patient outcomes in the intensive care unit (ICU) setting. Further research is needed to optimize training methods and enhance patient cooperation.

Effects of pulmonary function improvement devices in the pediatric population with cerebral palsy: Systematic review and meta-analysis of randomized clinical trials

INTRODUCTION

Enhancing lung function can significantly improve daily life functionality for children with cerebral palsy, leading to increased interest in respiratory physiotherapy training devices in clinical practice. This study aims to evaluate the efficacy of devices (inspiratory muscle training and feedback devices) for improving pulmonary function through various respiratory parameters.

METHODS

A systematic review with meta-analysis of randomized clinical trials was conducted in seven databases up until May 2023. The included studies focused on training inspiratory muscle function using specific devices (inspiratory muscle training and feedback devices) in children with cerebral palsy. The main outcomes were maximum expiratory pressure and maximum inspiratory pressure. Secondary outcomes included forced vital capacity, forced expiratory volume in 1 s, peak expiratory flow, and the Tiffenau index. The effects of respiratory treatment were calculated through the estimation of the effect size and its 95% confidence intervals. The risk of bias in the included studies was assessed using the Cochrane Collaboration's tool for assessing the risk of bias (RoB2).

RESULTS

Nine studies were included in the systematic review with meta-analysis, involving a total of 321 children aged between 6 and 18 years after secondary analyses were conducted. Feedback devices were found to be more effective in improving maximum expiratory pressure (effect size -0.604; confidence interval -1.368 to 0.161), peak expiratory flow, forced expiratory volume in 1 s, and forced vital capacity. Inspiratory muscle training devices yielded better effectiveness in improving maximum inspiratory pressure (effect size -0.500; confidence interval -1.259 to 0.259), the Tiffeneau index, and quality of life.

CONCLUSION

Both devices showed potential in improving pulmonary function in children with cerebral palsy. Further high-quality clinical trials are needed to determine the optimal dosage and the most beneficial device type for each pulmonary function parameter.

Benefits of inspiratory muscle training therapy in institutionalized adult people with cerebral palsy: A double-blind randomized controlled trial

BACKGROUND

Respiratory health problems are one of the main causes of morbidity and mortality in adult people with cerebral palsy (CP). The influence of respiratory muscle training has not yet been studied in this population group. The objective of the study was to evaluate and compare the efficacy of two protocols with inspiratory muscle training (IMT), low intensity and high intensity, to improve respiratory strength and pulmonary function in adults with CP.

METHODS

The study was a controlled, randomized, double-blind trial with allocation concealment. Twenty-seven institutionalized CP patients were recruited and randomly distributed in the high-intensity training group (HIT) or low-intensity training group (LIT). Over 8 weeks, an IMT protocol was followed 5 days/week, 10 series of 1 min with 1 min rest between them. HIT trained with a load of 40% of the maximum inspiratory pressure (MIP) and LIT with 20%. Respiratory strength and pulmonary function were evaluated.

RESULTS

After IMT intervention, MIP, maximum expiratory pressure, forced expiratory volume in 1 s (FEV1) and peak expiratory flow increased in both groups; in HIT 29%, 19%, 13%, and 8%, respectively (p = 0.000, p = 0.000, p = 0.002, p = 0.001) and in LIT 17%, 7%, 3%, and 4%, respectively (p = 0.000, p = 0.000, p = 0.049, p = 0.113). All the improvements were significantly higher in HIT than in LIT.

CONCLUSION

Inspiratory muscle training improved respiratory muscle strength and pulmonary function in adults with CP. Training with a 40% MIP load improved all the evaluated parameters and was the most effective treatment for adults with CP.

Respiratory Comorbidities and Complications of Cerebral Palsy

Respiratory complications are the most frequent cause of morbidity, mortality, and poor quality of life in children with cerebral palsy (CP) and represent the leading cause of hospitalizations. Several factors negatively influence the respiratory status of these children: lung parenchymal alterations and factors modifying the pulmonary pump function of chest and respiratory muscles, as well as concomitant pathologies that indirectly affect the respiratory function, such as sleep disorder, malnutrition, epilepsy, and pharmacological treatments. Early management of respiratory complications can improve the global health of children with CP and enhance quality of life for them and their caregivers.

Community-based respiratory health measures in children and young people with cerebral palsy: A scoping review

AIM

To identify, map, and describe outcome measurement domains and instruments used within a community setting to assess respiratory health in children and young people aged 1 to 18 years, diagnosed with cerebral palsy (CP).

METHOD

A scoping review methodology informed structured searches in nine databases, grey literature, and registries, conducted in August 2021 (updated in February 2023). Articles were screened for eligibility by two independent researchers. Any outcome measurement instruments used to assess respiratory health or associated impact were extracted, categorized, and mapped to health and health-related domains of the International Classification of Functioning, Disability, and Health.

RESULTS

Seventy-six outcome measurement instruments were identified across 78 articles worldwide between 1970 and 2023. These were categorized into 'Body functions and structures' (n = 20), 'Activity and performance' (n = 22), and 'Participation and quality of life' (n = 19), with a further 15 mapped to 'Health care resources use'.

INTERPRETATION

No consensus of 'what' to measure and 'how' to measure respiratory health in children and young people with CP was found. Moreover, many measures were not replicable in individuals with more severe forms of CP, excluding those at increased risk of respiratory-related morbidity and mortality. Further research is required to agree important outcome domains and associated measures in research and clinical practice.

WHAT THIS PAPER ADDS

A limited number and size of experimental designs were found. Seventy-six measures were identified to assess respiratory health in cerebral palsy. No consensus was found in 'what' or 'how' to measure respiratory health. Many measures were not replicable in children and young people at risk of poorer respiratory health outcomes. Children and young people with comorbidities and learning disability were frequently excluded from studies.

Supplementary Respiratory Therapy Improves Pulmonary Function in Pediatric Patients with Cerebral Palsy: A Systematic Review and Meta-Analysis

BACKGROUND

Despite medical advances, individuals with cerebral palsy (CP) face significant respiratory challenges, leading to heightened hospitalization rates and early mortality among this population. We hypothesize that integrating supplementary respiratory therapy into standard rehabilitation will result in significant improvements in pulmonary function, enhanced respiratory muscle strength, and an overall increase in the quality of life among pediatric patients with CP.

METHODS

A systematic search of literature across five databases was conducted, and random-effects meta-analyses were performed to assess the impact of supplementary respiratory therapy on (a) pulmonary function: forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FVC/FEV1 ratio, peak expiratory flow (PEF), and (b) respiratory muscle strength: maximal inspiratory and expiratory pressure (MIP, MEP), and (c) quality of life. Certainty of evidence was determined by the GRADE assessment.

RESULTS

Analysis of data from 11 eligible randomized controlled trials revealed clinically meaningful changes in pulmonary function. We found a relevant mean difference (MD) in absolute PEF of 0.50 L/s (95% confidence interval (CI): 0.19; 0.82 p = 0.0107). The certainty of the evidence ranged from moderate to high.

CONCLUSIONS

This study presents current evidence on the impact of various supplementary respiratory therapies for CP patients classified under gross motor function classification level I-IV, demonstrating clinically meaningful improvements in pulmonary function and respiratory muscle strength. These improvements suggest the potential for an enhanced quality of life. Our findings hold the promise of serving as a foundational reference for potential revisions to conventional rehabilitation care, incorporating supplementary respiratory therapy.

Physical activity of children and adolescents who use a wheelchair: a systematic review

Physical activity has numerous health benefits for people with physical disabilities. Nevertheless, activity levels are often below recommended levels. To promote physical activity among children and adolescents who use a wheelchair as their primary source of mobility, this systematic review explores the physical activity patterns of this group. A systematic search of PubMed, Sports Medicine & Education Index, Web of Science, and SPORTDiscus was performed, included articles were synthesized in terms of duration, intensity, and settings in which physical activity occurred, as well as the physical activity measurement methods. Nine articles were included. The mean overall physical activity level across the included studies was 98 minutes per day (range: 78-115 minutes per day). Two articles analysed the duration of physical activity at different intensities (very light physical activity, light physical activity (LPA), moderate to vigorous physical activity (MVPA) and intensities near to maximum). Within the included articles, both subjective and objective measurement methods were used. Due to the small number of articles, combined with small sample sizes, there is not enough evidence to answer the research questions sufficiently. Nevertheless, the review provides an overview of actual research and clearly shows that the physical activity values are insufficiently researched. There is a need for further research on the scope, types and settings of physical activity in the target group.

Addition of respiratory exercises to conventional rehabilitation for children and adolescents with cerebral palsy: a systematic review and meta-analysis

BACKGROUND

Respiratory dysfunctions are an important cause of morbidity and death in cerebral palsy (CP) populations. Respiratory exercises in addition to conventional rehabilitation have been suggested to improve respiratory status in CP patients. The objective of this systematic review and meta-analysis was to verify the effects of the addition of respiratory exercises to conventional rehabilitation on pulmonary function, functional capacity, respiratory muscle strength, gross motor function and quality of life in children and adolescents with CP.

METHODS

We searched for randomized controlled clinical trials in PubMed/Medline, Lilacs, SciELO, EMBASE and Physiotheraphy Evidence (PEDro) from their inception until July 2022 without language restrictions. Studies that included respiratory exercises (breathing exercise program; feedback respiratory training; incentive spirometer exercise; inspiratory muscle training; and combination of respiratory exercises + incentive spirometer exercise) in combination with conventional rehabilitation for children and adolescents with CP were evaluated by two independent reviewers. The mean difference (MD) and 95% confidence interval (CI) were estimated by random effect models.

RESULTS

Ten studies met the eligibility criteria, including 324 children aged from 6 to 16 years. The meta-analysis showed an improvement in inspiratory muscle strength of 22.96 cmH2O (18.63-27.27, n = 55) and pulmonary function of 0.60 (0.38-0.82, n = 98) for forced vital capacity (L); 0.22 (0.06-0.39, n = 98) for forced expiratory volume at 1 second (L); and 0.50 (0.05-0.04, n = 98) for peak expiratory flow (L/min). Functional skills in daily living activities improved in the intervention group. Caregivers' assistance of daily living activities, functional capacity, gross motor function and expiratory muscle strength showed a nonsignificant improvement. Social well-being and acceptance and functioning domains improved in only one study.

CONCLUSIONS

Emerging data show significant enhancements in inspiratory muscle strength and pulmonary function in CP patients after respiratory training in addition to conventional rehabilitation. There is no consensus on the frequency, type or intensity of respiratory exercises for children with and adolescents with CP.

Volume Incentive Spirometry Reduces Pulmonary Complications in Patients After Open Abdominal Surgery: A Randomized Clinical Trial

Objective

To compare the effect of diaphragmatic breathing and volume incentive spirometry (VIS) on hemodynamics, pulmonary function, and blood gas in patients following open abdominal surgery under general anesthesia.

Methods

A total of 58 patients who received open abdominal surgery were randomly assigned to the control group (n=29) undergoing diaphragmatic breathing exercises and the VIS group (n=29) undergoing VIS exercises. All the participants performed the six-minute walk test (6MWT) preoperatively to evaluate their functional capacity. Hemodynamic indexes, pulmonary function tests, and blood gas indexes were recorded before surgery and on the 1st, 3rd, and 5th postoperative day.

Results

The functional capacity was not significantly different between the two groups during the preoperative period (P >0.05). At 3 days and 5 days postoperatively, patients in the VIS group had a significantly higher SpO2 than that in the control group (P <0.05). Pulmonary function test values were reduced in both two groups postoperatively when compared to the preoperative values but improved for three and five days afterward (P <0.05). Of note, the significantly elevated levels of peak expiratory flow (PEF), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were observed on the 1st, 3rd, and 5th postoperative days in the VIS group compared with those in the control group (P <0.05). Besides, bass excess (BE), and pH values were significantly higher in the VIS group on the 1st postoperative day than those in the control group (P <0.05).

Conclusion

Diaphragmatic breathing and VIS could improve postoperative pulmonary function, but VIS exercise might be a better option for improving hemodynamics, pulmonary function, and blood gas for patients after open abdominal surgery, hence lowering the incidence of postoperative pulmonary complications.

Effect of Threshold Inspiratory Muscle Training on Functional Fitness and Respiratory Muscle Strength Compared to Incentive Spirometry in Children and Adolescents With Obesity: A Randomized Controlled Trial

BACKGROUND

To determine the effect of threshold inspiratory muscle training (IMT) on functional fitness and respiratory muscle strength (RMS) compared to incentive spirometry (IS) in children/adolescents with obesity.

METHODS

A total of 60 obese children/adolescents aged 8-15 years were randomized into the threshold IMT group (n = 20), the IS group (n = 20), or the control group (n = 20). The IMT group performed 30 inspiratory breaths with the intensity set at 40% of baseline maximal inspiratory pressure (MIP) twice daily for 8 weeks; the IS group performed 30 breaths with sustained maximum inspiration twice daily for 8 weeks; and, the control group was assigned no training device for 8 weeks. Six-min walk test (6-MWT), RMS, and spirometry were compared between baseline and 8 weeks.

RESULTS

Six-MWT distance (528.5 ± 36.2 vs. 561.5 ± 35.2 m, p = 0.002) and MIP (121.2 ± 26.8 vs. 135.3 ± 32.1%Predicted, p = 0.03) were significantly improved after 8 weeks of IMT training. There was no significant difference in any evaluated pulmonary function parameters between baseline and 8 weeks in the IS or control groups; however, 6-MWT distance demonstrated a trend toward significant improvement in the IS group (526.9 ± 59.1 vs.549.0 ± 50.6 m, p = 0.10). No significant difference among groups was found for any variable relative to change from baseline to post-training.

CONCLUSION

Eight weeks of threshold IMT training significantly improved both inspiratory muscle strength (MIP) and functional fitness (6-MWT) in children/adolescents with obesity. Eight weeks of IS training yielded a trend toward significantly improved functional fitness.

Effects of additional inspiratory muscle training on mobility capacity and respiratory strength for school-children and adolescents with cerebral palsy: a randomized controlled trial

BACKGROUND

Children and adolescents with cerebral palsy often have poor respiratory function, which is often not addressed.

OBJECTIVE

To examine if adding inspiratory muscle training to sensorimotor exercises would improve mobility capacity and respiratory function in children and adolescents with cerebral palsy.

METHODS

Forty school-children and adolescents with cerebral palsy aged 8-15 years with Gross Motor Function Classification System I-III, participated in this randomized controlled trial. The experimental group received 45 min of sensorimotor physical therapy in addition to 15 min of inspiratory muscle training for 18 sessions over six weeks. In contrast, the control group received 45 min of sensorimotor training session, three times a week over six weeks. The primary outcome measure was the six-minute walk test. The secondary outcome measures were maximal inspiratory and maximal expiratory pressure, as well as pulmonary function tests.

RESULTS

Time by group interaction showed no statistical significance between the groups in any outcome measures except for peak expiratory flow. The mean difference of 9.6 cm H₂O (95% CI: 2.3, 16.8) in the MIP from baseline to 2-month follow-up supports the experimental intervention. Post-training, the between-group mean difference was 19.8 (95% CI: -18.0, 57.6) meter in the six-minute walk test.

CONCLUSION

Adding inspiratory muscle training to sensorimotor physical therapy did not impact mobility capacity in children and adolescents with cerebral palsy.

Effects of Physical Therapist Intervention on Pulmonary Function in Children With Cerebral Palsy: A Systematic Review and Meta-Analysis

OBJECTIVE

The purpose of this study was to evaluate the effects of physical therapy on pulmonary function and respiratory muscle strength in children with cerebral palsy (CP).

METHODS

A search of 10 databases was conducted for this systematic review. Initially, there were no language, study design, or time frame restrictions. All studies assessing the effect of physical therapy on the respiratory system in children with CP were included. Two reviewers independently extracted and documented data. The data extracted included description of the intervention (duration, therapeutic method) and study results (change of spirometric parameters, respiratory muscle strength). The effects of physical therapist treatment were calculated using software.

RESULTS

A total of 269 children aged 5 to 18 years from 10 studies were included. The included studies consisted of 5 different therapeutic methods (inspiratory muscle training [IMT], aerobic training, swimming, respiratory exercise, exercise with elastic bands). Physical therapist intervention led to a significant increase in the maximal expiratory pressure (MEP) (I2 = 0%), peak expiratory flow (I2 = 0%), and maximum oxygen consumption (I2 = 37%). A separate analysis of the most frequently used therapy (IMT) showed a positive effect on MEP (I2 = 0%) and maximal inspiratory pressure (I2 = 35%).

CONCLUSION

Various forms of physical therapy have potential to demonstrate a positive effect on maximal inspiratory pressure, MEP, and peak expiratory flow in children with CP. There is no possibility to recommend the best method and duration of the physical therapy; however, it can be suggested that physical therapy should be applied for at least 4 weeks and include IMT.

IMPACT

CP is one of the most common causes of physical disabilities in children, and pulmonary dysfunction is the leading cause of death in people with CP. Thus, it is warranted to seek different approaches that may improve pulmonary function in people with CP. This review has shown that various forms of physical therapy have potential to improve the pulmonary function of children with CP.

Standardized Outcomes Measures in Physical Therapy Practice for Treatment and Rehabilitation of Cerebral PALSY: A Systematic Review

Cerebral palsy (CP) treatment includes physical therapy and various complementary therapies to the standard clinical treatment. However, there are not many reviews that focus on the methods used and evaluation procedures. This study aims to analyze which tools are most suitable for the evaluation and methodology of patients with CP treated with physical therapy. Following the PRISMA statement, through a PICOS strategy, PubMed/MEDLINE, Web of Science (WOS), Scopus, Science Direct, and Scielo were searched with the following terms: cerebral palsy AND (physical therapy modalities OR therapeutics) AND outcome assessment. The methodological quality of the RCTs was assessed with the Evidence Project risk of bias tool. Thirty-seven RCTs and six RCT protocols, comprising 1359 participants with different types of CP: spastic hemiplegia/paresis, spastic diplegia/paresis, and spastic CP, met the inclusion criteria, uncovering 21 variables measured through 77 different instruments and several interventions. The therapies most widely used in CP are gaming or technology-assisted therapies, aerobic training, hippotherapy, music therapy, gait training, and aquatic exercises. This study provides an overview of what the authors used in the neurorehabilitation field through procedure evaluation and checking the technological advance that began to be used.

The Synergistic Effects of a Complementary Physiotherapeutic Scheme in the Psychological and Nutritional Treatment in a Teenage Girl with Type 1 Diabetes Mellitus, Anxiety Disorder and Anorexia Nervosa

Type 1 diabetes mellitus (T1DM) is a chronic disease that can affect the physical and mental health of children and adolescents, often leading to anxiety disorders with chronic activation of the hypothalamic axis (HPA). Moreover, a great proportion of adolescents with T1DM also demonstrate anorexia nervosa (AN), due to the increased preoccupation with food and the need to have an acceptable body image. Herein is described the first case study of an adolescent patient diagnosed with T1DM, anxiety disorder (AD), and AN. A 14-year-old girl with T1DM since the age of 12 years presented weight loss at age 13 years and 3 months and low body mass index (BMI), which did not improve despite dietary recommendations and adequate disease control. Additionally, she presented menstrual disorders at the age of 12 years and 11 months (menstrual age 12 years and 1 month). A psychological evaluation of the teenager was conducted using a semi-structured interview that assessed perceived stress, health status, quality of life, and depression. AD and AN were diagnosed and the patient initiated an intervention focusing on psychological health and nutrition and which incorporated physiotherapeutic relaxation sessions and breathing exercises. After 3 months of treatment, the patient’s BMI was increased, and a normal menstrual cycle was apparent. These results have since remained consistent. Stress leads to the appearance of AN and menstrual disorders. Therefore, physiotherapeutic programs could reduce stress and effectively ameliorate AN and AD.

Effectiveness of the manual diaphragmatic stretching technique on respiratory function in cerebral palsy: A randomised controlled trial

BACKGROUND

Respiratory failure resulting from diaphragmatic muscle weakness is a major cause of long-term hospitalization in children with cerebral palsy (CP). Manual diaphragmatic stretching technique (MDST) can be directly applied to stretch diaphragmatic muscle and has been reported to improve respiratory function in patients with asthma and COPD. However, there have been no studies among CP. This study aimed to examine the effects of a six-week MDST course on respiratory function among CP.

METHODS

Fifty-three children with spastic CP were randomly assigned to experimental (n = 27) and control (n = 26) groups. The experimental group received MDST on non-consecutive days, three days per week for six weeks alongside standard physiotherapy (SDPT), while the control group received only SDPT. The outcome variables were diaphragmatic mobility, pulmonary function and chest wall expansion.

RESULTS

MDST significantly improved diaphragmatic mobility on both sides of the body, with a between-group difference of 0.97 cm (95% CI 0.55-1.39 cm, p < 0.001) for the right side and 0.82 cm (95% CI 0.35-1.29 cm, p = 0.001) for the left side. MDST significantly improved chest wall expansion at the xiphoid process and umbilical levels, with between-group differences of 0.57 cm (95% CI 0.12-1.20 cm, p = 0.013) and 0.87 cm (95% CI 0.31-1.43 cm, p = 0.003), respectively. There was no significant difference in pulmonary function testing between the groups.

CONCLUSION

MDST could significantly improve diaphragmatic mobility, and lower and abdominal chest wall expansion, among children with CP. Therefore, MDST could be considered as an additional technique for physiotherapy programmes, to improve diaphragmatic function in spastic CP.

Influence of Chest and Diaphragm Manual Therapy on the Spirometry Parameters in Patients with Cerebral Palsy: A Pilot Study

Objective

To evaluate the influence of manual therapy of the chest and diaphragm on the spirometry parameters in patients with cerebral palsy (CP).

Method

The study was carried out on 20 youths with CP. All participated in 6 sessions (3 sham and 3 actual), with measurements of spirometry at baseline, postsham therapies 1 and 3, before actual therapy, and postactual therapy sessions 1 and 3. Two manual techniques were included: soft tissue mobilization of the chest and the diaphragm.

Results

After the first actual therapy, there was a significant (p < 0.01) improvement in forced vital capacity (FVC) by 0.23 L (8% of the average predicted value) and forced expiratory volume in one second (FEV₁) by 0.18 L (7% of the average predicted value) as compared to results before the therapy. Change in FVC parameter was clinically significant, whereas change in FEV₁ was not clinically significant. After sham therapy, there was no improvement in spirometry parameters as compared to baseline results.

Conclusion

Single-time manual therapy of the chest and diaphragm has a positive effect on FVC and FEV₁.

Effect of incentive spirometer exercise combined with physical therapy on pulmonary functions in children with cerebral palsy

Background/aims

Children with cerebral palsy have poorer pulmonary function than average healthy people because they typically have decreased mobility of the chest wall, deviation of chest wall structure and weak respiratory muscles. The aim of this study was to examine the effect of the incentive spirometer exercise on pulmonary functions in children with cerebral palsy, and the effects of the incentive spirometer exercise according to Gross Motor Function Classification System level.

Methods

A total of 50 patients with spastic cerebral palsy aged between 8 and 12 years were randomly divided into two groups: the study group and the control group. Both groups received a physiotherapy exercise programme with the aim of enhancing gross motor and respiratory function for 60 minutes a day, 3 days a week for 8 weeks. The study group received the additional incentive spirometer exercise. Both groups had pulmonary function testing before the study (baseline), halfway through the intervention (at 4 weeks) and then at the end of the intervention (after 8 weeks).

Results

Significant improvements in forced expiratory volume in 1 second, forced vital capacity and maximal mid-expiratory flow were found in the study group, but not in the control group.

Conclusions

The incentive spirometer exercise, along with physiotherapy exercises, are effective in improving pulmonary functions than physiotherapy exercises alone.

Effect of respiratory therapy on pulmonary functions in children with cerebral palsy: a systematic review

Background

Children with cerebral palsy (CP) are at risk for respiratory dysfunction. Early initiation of pulmonary rehabilitation in addition to conventional physical therapy may result in improvement and maintenance of chest mobility and respiratory function. However, empirical support for respiratory therapy is limited. The aim of the review was to assess the evidence of the effectiveness of respiratory therapy on pulmonary functions in children with CP.

Methods

Four electronic databases (PubMed, Cochrane Library, Physiotherapy Evidence Database (PEDro), and Google Scholar) were searched till December 2019 using predefined terms by two independent reviewers. Randomized controlled trials published in English were included if they met the following criteria: population—children with different types of CP of both sex, aged up to 18 years; intervention—respiratory therapy; outcomes—pulmonary functions. Eight studies with 235 participants only met the inclusion criteria and were included in this review. Predefined data were tabulated using American Academy for Cerebral Palsy and Developmental Medicine by two reviewers and verified by a third reviewer. Methodological quality was assessed using rating system of quality assessment and PEDro scale; also, levels of evidence adopted from modified Sacket’s scale were used for each outcome.

Results

The quality of studies ranged from excellent (one study) to good (five studies) and fair (two studies). The results showed level 1 (six studies) and level 2 (two studies) on modified Sacket’s scale for level of evidence. Lack of allocation concealment and blinding was the major risk of bias in the included studies.

Conclusions

Meta-analysis revealed significant difference in the improvement of vital capacity, peak expiratory flow, and forced expiratory volume at 1 s in favor of the study groups. However, there is a need for high-quality studies to draw a clear conclusion.

Accurate Spirometry with Integrated Barometric Sensors in Face-Worn Garments

Cardiorespiratory (CR) signals are crucial vital signs for fitness condition tracking, medical diagnosis, and athlete performance evaluation. Monitoring such signals in real-life settings is among the most widespread applications of wearable computing. We investigate how miniaturized barometers can be used to perform accurate spirometry in a wearable system that is built on off-the-shelf training masks often used by athletes as a training aid. We perform an evaluation where differential barometric pressure sensors are compared concurrently with a digital spirometer, during an experimental setting of clinical forced vital capacity (FVC) test procedures with 20 participants. The relationship between the two instruments is derived by mathematical modeling first, then by various regression methods from experiment data. The results show that the error of FVC vital values between the two instruments can be as low as 2∼3%. Beyond clinical tests, the method can also measure continuous tidal breathing air volumes with a 1∼3% error margin. Overall, we conclude that barometers with millimeter footprints embedded in face mask apparel can perform similarly to a digital spirometer to monitor breathing airflow and volume in pulmonary function tests.

Evaluation and Management of Respiratory Illness in Children With Cerebral Palsy

Cerebral palsy (CP) is the most common cause of disability in childhood. Respiratory illness is the most common cause of mortality, morbidity, and poor quality of life in the most severely affected children. Respiratory illness is caused by multiple and combined factors. This review describes these factors and discusses assessments and treatments. Oropharyngeal dysphagia causes pulmonary aspiration of food, drink, and saliva. Speech pathology assessments evaluate safety and adequacy of nutritional intake. Management is holistic and may include dental care, and interventions to improve nutritional intake, and ease, and efficiency of feeding. Behavioral, medical, and surgical approaches to drooling aim to reduce salivary aspiration. Gastrointestinal dysfunction, leading to aspiration from reflux, should be assessed objectively, and may be managed by lifestyle changes, medications, or surgical interventions. The motor disorder that defines cerebral palsy may impair fitness, breathing mechanics, effective coughing, and cause scoliosis in individuals with severe impairments; therefore, interventions should maximize physical, musculoskeletal functions. Airway clearance techniques help to clear secretions. Upper airway obstruction may be treated with medications and/or surgery. Malnutrition leads to poor general health and susceptibility to infection, and improved nutritional intake may improve not only respiratory health but also constipation, gastroesophageal reflux, and participation in activities. There is some evidence that children with CP carry pathogenic bacteria. Prophylactic antibiotics may be considered for children with recurrent exacerbations. Uncontrolled seizures place children with CP at risk of respiratory illness by increasing their risk of salivary aspiration; therefore optimal control of epilepsy may reduce respiratory illness. Respiratory illnesses in children with CP are sometimes diagnosed as asthma; a short trial of asthma medications may be considered, but should be discontinued if ineffective. Overall, management of respiratory illness in children with CP is complex and needs well-coordinated multidisciplinary teams who communicate clearly with families. Regular immunizations, including annual influenza vaccination, should be encouraged, as well as good oral hygiene. Treatments should aim to improve quality of life for children and families and reduce burden of care for carers.

The impact of breathing rate on the cardiac autonomic dynamics among children with cerebral palsy compared to typically developed controls

PURPOSE

To describe the immediate effect of breathing rate on heart rate (HR) and heart rate variability (HRV) in children with cerebral palsy (CP) and a control group of typically developed (TD) age and gender-matched children.

METHODS

Twenty children with CP at gross motor function classification system levels I-III and 20 TD children aged 6-11 participated in the study. HR was monitored at rest and during paced breathing with biofeedback. Respiratory measures were assessed by KoKo spirometry.

RESULTS

Children with CP have lower spirometry and HRV values at rest compared to TD children. The mean reduction of breathing rate during paced breathing among children with CP was significantly smaller. Nonetheless, while practicing paced breathing, both groups reduced their breathing rate and increased their HRV.

CONCLUSIONS

The results of the current work present the immediate effect of paced breathing on HRV parameters in CP and TD children. Further studies are needed to investigate the effect of long-term treatment focusing on paced breathing for children with CP.

Pulmonary Rehabilitation in a Patient With Bronchiectasis and Underlying Cerebral Palsy: A Case Presentation

Bronchiectasis is a chronic pulmonary disease characterized by the permanent dilatation of the airways, with recurrent infections. As the disease progresses, extrapulmonary symptoms manifest. If the patient with bronchiectasis has an underlying central nervous system disease such as cerebral palsy (CP), extrapulmonary functions decline faster. The co-occurrence of these 2 diseases may make care more complex, and there have been no reports about pulmonary rehabilitation (PR) in this class of patients. Here, we present a patient with bronchiectasis and underlying CP who showed marked improvement of pulmonary function and clinical symptoms after 6 weeks of a patient-specific intensive PR program.

Systematic review of physical activity and exercise interventions to improve health, fitness and well-being of children and young people who use wheelchairs

AIM

To perform a systematic review establishing the current evidence base for physical activity and exercise interventions that promote health, fitness and well-being, rather than specific functional improvements, for children who use wheelchairs.

DESIGN

A systematic review using a mixed methods design.

DATA SOURCES

A wide range of databases, including Web of Science, PubMed, BMJ Best Practice, NHS EED, CINAHL, AMED, NICAN, PsychINFO, were searched for quantitative, qualitative and health economics evidence.

ELIGIBILITY

participants: children/young people aged >25 years who use a wheelchair, or parents and therapists/carers. Intervention: home-based or community-based physical activity to improve health, fitness and well-being.

RESULTS

Thirty quantitative studies that measured indicators of health, fitness and well-being and one qualitative study were included. Studies were very heterogeneous preventing a meta-analysis, and the risk of bias was generally high. Most studies focused on children with cerebral palsy and used an outcome measure of walking or standing, indicating that they were generally designed for children with already good motor function and mobility. Improvements in health, fitness and well-being were found across the range of outcome types. There were no reports of negative changes. No economics evidence was found.

CONCLUSIONS

It was found that children who use wheelchairs can participate in physical activity interventions safely. The paucity of robust studies evaluating interventions to improve health and fitness is concerning. This hinders adequate policymaking and guidance for practitioners, and requires urgent attention. However, the evidence that does exist suggests that children who use wheelchairs are able to experience the positive benefits associated with appropriately designed exercise.
