Spinal posture, mobility, and position sense in adolescents with chest wall deformities: a comparison of pectus excavatum, pectus carinatum and healthy peers.

PURPOSE: The study aimed to compare spinal posture, mobility, and position sense in adolescents with pectus excavatum (PE), pectus carinatum (PC), and healthy control (HC). METHODS: 22 with PE, 22 with PC, and 21 HC were included in the study. The spinal posture (thoracic kyphosis, lumbar lordosis, pelvic tilt, thoracic, lumbar, pelvic lateral tilt angles) and mobility (thoracic, lumbar, hip/sacral, and overall, in the sagittal and frontal plane) with the spinal mouse, and spinal position sense (repositing errors) with the inclinometer were assessed. RESULTS: The thoracic kyphosis angle of PE and PC was higher than in HC (p < 0.001; p = 0.001). Hip/sacral mobility in the sagittal plane was lower in the PE and PC than control, respectively (p < 0.001; p < 0.001). Overall sagittal spinal mobility (p:0.007) and hip/sacral mobility in the frontal plane (p:0.002) were lower in the PC than in HC. Overall frontal spinal mobility was lower in the PE and PC than in HC (p:0.002; p:0.014). The PE and PC repositing errors were higher (p < 0.001; p:0.014). CONCLUSION: The study found that adolescents with PE and PC had decreased spinal mobility, spinal alignment disorders, and a decline in spinal position sense. It is important not to overlook the spine during physical examinations of adolescents with chest wall deformities. In clinical practice, we suggest that adolescents with chest deformities should undergo a spine evaluation and be referred for physical therapy to manage spinal disorders.

Favourable outcome in survivors of CPR-related chest wall injuries.

BACKGROUND: There is a lack of studies focusing on long-term chest function after chest wall injury due to cardiopulmonary resuscitation (CPR). The purpose of this cross-sectional study was to investigate long-term pain, lung function, physical function, and fracture healing after manual or mechanical CPR and in patients with and without flail chest. METHODS: Patients experiencing out-of-hospital cardiac arrest between 2013 and 2020 and transported to Sahlgrenska University Hospital were identified. Survivors who had undergone a computed tomography (CT) showing chest wall injury were contacted. Thirty-five patients answered a questionnaire regarding pain, physical function, and quality of life and 25 also attended a clinical examination to measure the respiratory and physical functions 3.9 (SD 1.7, min 2-max 8) years after the CPR. In addition, 22 patients underwent an additional CT scan to evaluate fracture healing. RESULTS: The initial CT showed bilateral rib fractures in all but one patient and sternum fracture in 69 %. At the time of the follow-up none of the patients had persistent pain, however, two patients were experiencing local discomfort in the chest wall. Lung function and thoracic expansion were significantly lower compared to reference values (FVC 14 %, FEV1 18 %, PEF 10 % and thoracic expansion 63 %) (p < 0.05). Three of the patients had remaining unhealed injuries. Patients who had received mechanical CPR in additional to manual CPR had a lower peak expiratory flow (80 vs 98 % of predicted values) (p=0.030) =0.030) and those having flail chest had less range of motion in the thoracic spine (84 vs 127 % of predicted) (p = 0.019) otherwise the results were similar between the groups. CONCLUSION: None of the survivors had long-term pain after CPR-related chest wall injuries. Despite decreased lower lung function and thoracic expansion, most patients had no limitations in physical mobility. Only minor differences were seen after manual vs. mechanical CPR or with and without flail chest.

Respiratory and chest wall mechanics in very preterm infants.

Data on static compliance of the chest wall (Ccw) in preterm infants are scarce. We characterized the static compliance of the lung (CL) and Ccw to determine their relative contribution to static compliance of the respiratory system (Crs) in very preterm infants at 36 wk postmenstrual age (PMA). We also aimed to investigate how these compliances were influenced by the presence of bronchopulmonary dysplasia (BPD) and impacted breathing variables. Airway opening pressure, esophageal pressure, and tidal volume (VT) were measured simultaneously during a short apnea evoked by the Hering-Breuer reflex. We computed tidal breathing variables, airway resistance (R), and dynamic lung compliance (CL,dyn), inspiratory capacity (IC), and Crs, CL, and Ccw. Functional residual capacity was assessed by the multiple breath washout technique (FRCmbw). Breathing variables, compliances, and lung volumes were adjusted for body weight. Twenty-three preterm infants born at 27.2 ± 2.0 wk gestational age (GA) were studied at 36.6 ± 0.6 wk PMA. Median and interquartile range (IQR) Crs/kg is 0.69 (0.6), CL/kg 0.95 (1.0), and Ccw/kg 3.0 (2.4). Infants with BPD (n = 11) had lower Crs/kg (P = 0.013), CL/kg (P = 0.019), and Ccw/kg (P = 0.027) compared with infants without BPD. Ccw/CL ratio was equal between groups. FRCmbw/kg (P = 0.044) and IC/kg (P = 0.005) were decreased in infants with BPD. Infants with BPD have reduced static compliance of the respiratory system, the lungs, and chest wall. Decreased Crs, CL, and Ccw in infants with BPD explain the lower FRC and IC seen in these infants.NEW & NOTEWORTHY Data on chest wall compliance in very preterm infants in the postsurfactant era are scarce. To our knowledge, we are the first group to report data on static respiratory system compliance (Crs), lung compliance (CL), and chest wall compliance (Ccw) in preterm infants with and without bronchopulmonary dysplasia (BPD) in the postsurfactant era.

Thoracoabdominal Wall Motion-Guided Biofeedback Treatment of Abdominal Distention: A Randomized Placebo-Controlled Trial.

BACKGROUND & AIMS: Abdominal distention results from abdominophrenic dyssynergia (ie, diaphragmatic contraction and abdominal wall relaxation) in patients with disorders of gut-brain interaction. This study aimed to validate a simple biofeedback procedure, guided by abdominothoracic wall motion, for treating abdominal distention. METHODS: In this randomized, parallel, placebo-controlled trial, 42 consecutive patients (36 women and 6 men; ages 17-64 years) with meal-triggered visible abdominal distention were recruited. Recordings of abdominal and thoracic wall motion were obtained using inductance plethysmography via adaptable belts. The signal was shown to patients in the biofeedback group, who were taught to mobilize the diaphragm. In contrast, the signal was not shown to the patients in the placebo group, who were given a placebo capsule. Three sessions were performed over a 4-week intervention period, with instructions to perform exercises (biofeedback group) or to take placebo 3 times per day (control group) at home. Outcomes were assessed through response to an offending meal (changes in abdominothoracic electromyographic activity and girth) and clinical symptoms measured using daily scales for 7 days. RESULTS: Patients in the biofeedback group (n = 19) learned to correct abdominophrenic dyssynergia triggered by the offending meal (intercostal activity decreased by a mean ± SE of 82% ± 10%, anterior wall activity increased by a mean ± SE of 97% ± 6%, and increase in girth was a mean ± SE of 108% ± 4% smaller) and experienced improved clinical symptoms (abdominal distention scores decreased by a mean ± SE of 66% ± 5%). These effects were not observed in the placebo group (all, P < .002). CONCLUSIONS: Abdominothoracic wall movements serve as an effective biofeedback signal for correcting abdominophrenic dyssynergia and abdominal distention in patients with disorders of gut-brain interaction.

The Best of Chest Wall Reconstruction: Principles and Clinical Application for Complex Oncologic and Sternal Defects.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Appraise and evaluate risk factors for respiratory compromise following oncologic resection. 2. Outline and apply an algorithmic approach to reconstruction of the chest wall based on defect composition, size, and characteristics of surrounding tissue. 3. Recognize and evaluate indications for and types of skeletal stabilization of the chest wall. 4. Critically consider, compare, and select pedicled and free flaps for chest wall reconstruction that do not impair residual respiratory function or skeletal stability. SUMMARY: Chest wall reconstruction restores respiratory function, provides protection for underlying viscera, and supports the shoulder girdle. Common indications for chest wall reconstruction include neoplasms, trauma, infectious processes, and congenital defects. Loss of chest wall integrity can result in respiratory and cardiac compromise and upper extremity instability. Advances in reconstructive techniques have expanded the resectability of large complex oncologic tumors by safely and reliably restoring chest wall integrity in an immediate fashion with minimal or no secondary deficits. The purpose of this article is to provide the reader with current evidenced-based knowledge to optimize care of patients requiring chest wall reconstruction. This article discusses the evaluation and management of oncologic chest wall defects, reviews controversial considerations in chest wall reconstruction, and provides an algorithm for the reconstruction of complex chest wall defects. Respiratory preservation, semirigid stabilization, and longevity are key when reconstructing chest wall defects.

Investigating the efficacy of chest pressure for direct current cardioversion in atrial fibrillation: a randomised control trial protocol (Pressure-AF).

INTRODUCTION: Atrial fibrillation (AF) is the most common sustained arrhythmia worldwide. Direct current cardioversion is commonly used to restore sinus rhythm in patients with AF. Chest pressure may improve cardioversion success through decreasing transthoracic impedance and increasing cardiac energy delivery. We aim to assess the efficacy and safety of routine chest pressure with direct current cardioversion for AF. METHODS AND ANALYSIS: Multicentre, double blind (patient and outcome assessment), randomised clinical trial based in New South Wales, Australia. Patients will be randomised 1:1 to control and interventional arms. The control group will receive four sequential biphasic shocks of 150 J, 200 J, 360 J and 360 J with chest pressure on the last shock, until cardioversion success. The intervention group will receive the same shocks with chest pressure from the first defibrillation. Pads will be placed in an anteroposterior position. Success of cardioversion will be defined as sinus rhythm at 1 min after shock. The primary outcome will be total energy provided. Secondary outcomes will be success of first shock to achieve cardioversion, transthoracic impedance and sinus rhythm at post cardioversion ECG. ETHICS AND DISSEMINATION: Ethics approval has been confirmed at all participating sites via the Research Ethics Governance Information System. The trial has been registered on the Australia New Zealand Clinical Trials Registry (ACTRN12620001028998). De-identified patient level data will be available to reputable researchers who provide sound analysis proposals.

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.

A computer tablet software can quantify the deviation of scapula medial border from the thoracic wall during clinical assessment of scapula dyskinesis.

PURPOSE: Aim of this study is to establish an objective and easily applicable method that will allow clinicians to quantitatively assess scapular dyskinesis during clinical examination using a computer tablet software. Hypothesis is that dyskinetic scapulae present greater motion-deviation from the thoracic wall-compared to the non-dyskinetic ones and that the software will be able to record those differences. METHODS: Twenty-five patients and 19 healthy individuals were clinically evaluated for the presence of dyskinesis or not. According to the clinical diagnosis, the observations were divided into three groups; A. Dyskinetic scapulae with symptoms (n = 25), B. Contralateral non-dyskinetic scapulae without symptoms (n = 25), C. Healthy control scapulae (n = 38). Then, all individuals were tested using a tablet with the PIVOT™ image-based analysis software (PIVOT, Impellia, Pittsburgh, PA, USA). The motion produced by the scapula medial border and inferior angle deviation from the thoracic wall was recorded. RESULTS: The deviation of the medial border and inferior angle of the scapula from the thoracic wall was 24.6 ± 7.3 mm in Group A, 14.7 ± 4.9 mm in Group B, and 12.4 ± 5.2 mm in Group C. The motion recorded in the dyskinetic scapulae group was significantly greater than both the contralateral non-dyskinetic scapulae group (p < 0.01) and the healthy control scapulae group (p < 0.01). CONCLUSION: The PIVOT™ software was efficient to detect significant differences in the motion between dyskinetic and non-dyskinetic scapulae. This system can support the clinical diagnosis of dyskinesis with a numeric value, which not only contributes to scapula dyskinesis grading but also to the evaluation of the progress and efficacy of the applied treatment, thus providing a feedback to the clinician and the patient. LEVEL OF EVIDENCE: IV, laboratory study.

EarLy Exercise in blunt Chest wall Trauma: a feasibility trial (ELECT Trial).

BACKGROUND: The aim was to complete a feasibility study that would test the methods of the main trial, that will investigate whether early thoracic and shoulder girdle exercises reduce chronic pain in patients with blunt chest wall trauma, when compared with normal care. METHODS: A single centre, parallel, feasibility randomised controlled trial was completed at a University Teaching Hospital in Wales between June and September 2019. Adult patients with blunt chest wall trauma, admitted to hospital for greater than 24 hours, with no concurrent, immediately life-threatening injuries, were included. The intervention was a simple physiotherapy programme comprising thoracic and shoulder girdle exercises. Feasibility outcome measures included: primary outcomes: (1) 80% or more of identified eligible patients were approached for potential recruitment to the trial (2) 30% or less of approached, eligible patients dissented to participate in the trial; secondary outcomes: (3) follow-up data for patient secondary outcomes can be collected for 80% or more of patients, (4) there should be no greater than 10% increase in serious adverse events in the intervention group compared with the control group. RESULTS: A total of 19/19 (100%) patients were deemed eligible for the trial and were approached for participation, 5/19 (26%) eligible patients declined to participate in the trial, follow-up data were collected for n=10/14 (71%) patients and there were no serious adverse events reported in either group. CONCLUSIONS: We have demonstrated that a fully powered randomised clinical trial of the EarLy Exercise in blunt Chest wall Trauma Trial is feasible. TRIAL REGISTRATION NUMBER: ISRCTN16197429.

Yoga in Burn: Role of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full-thickness circumferential burns of the chest.

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.

The vacuum treatment for the pectus excavatum thickened subcutaneous fat of the chest wall and is effective in preteenagers.

PURPOSE: We report effects of treatment for pectus excavatum (PE) with a Vacuum Bell (VB). MATERIALS AND METHODS: Fifteen patients (13 males and 2 females) undergoing VB therapy over 6 years, aged 6-17 years (mean: 11.1 years), were divided into two Groups: Group 1 (G1), preteenagers (< 13 years); Group 2 (G2), teenagers (≧ 13 years). We retrospectively recorded changes in depth of depression and the Haller index. RESULTS: The depth of depression reduced in 93.3% of 15 patients (mean; 8.7 mm). Minimal change occurred in the Haller index but the subcutaneous fat thickened significantly (11/15 patients). The improvement rate on elevation of the chest wall was better in G1 than G2 (G1: 54.0% vs G2: 51.3%). CONCLUSION: The maximum depth of depression improved in PE patients as a result of thickening of subcutaneous fat. VB is most effective in preteenagers with PE.

Chest Wall Mobility: Identification of Underlying Predictors.

OBJECTIVE: The purpose of this study was to identify factors contributing to normal mobility or hypermobility of the chest wall. METHODS: Seventy-eight young adults were divided into 2 groups: patients with normal mobility (group 1, n = 40) and hypermobility of the chest wall (group 2, n = 38). The mean mobility of the chest wall in groups 1 and 2 was 9.9 and 6.1 cm, respectively. The mean age of groups 1 and 2 was 22.2 and 21.5 years, respectively. The Brief Symptom Inventory, State-Trait Anxiety Inventory, Beck Depression Inventory, and the Perceived Stress Scale were used to evaluate the psychometric properties. Quality of life was assessed using 12-Item Short Form Health Survey. Smoking status was determined via self-report of current smoking status. Chest wall mobility was measured using thoracic and axillary cirtometry. Pulmonary functions were evaluated using a Spirobank II device. Subsequently, forced vital capacity (FVC), forced expiratory volume in 1 second, peak expiratory flow, and forced expiratory flow 25% to 75% were verified. Carefusion Micro RPM and the 6-minute walk test were used to evaluate maximal respiratory pressures and functional capacity, respectively. RESULTS: With backward linear regression models, FVC and obsessive-compulsive traits were significant predictors of chest wall mobility (R²â€¯= 0.27; P < .001 and P = .01, respectively). In logistic regression models, FVC, maximum inspiratory pressure, and obsessive-compulsive traits were significant predictors of normal mobility/hypermobility of the chest wall (R²â€¯= 0.42; P < .001, P = .01, and P = .03, respectively). CONCLUSION: Forced vital capacity, maximum inspiratory pressure, and obsessive-compulsive traits are significant predictors of chest wall mobility and normal mobility or hypermobility of the chest wall.

The chest wall gender divide: females have better cardiopulmonary function and exercise tolerance despite worse deformity in pectus excavatum.

PURPOSE: Pectus excavatum (PE) is a chest wall deformity of variable severity and symptomatology. Existing female-specific literature highlights breast asymmetry and cosmetic reconstruction. We sought to evaluate gender differences in cardiopulmonary function. METHODS: Cardiac MRIs, pulmonary function tests (PFTs), and cardiopulmonary exercise tests (CPETs) were reviewed in 345 patients undergoing preoperative evaluation for PE. Regression modeling was used to evaluate associations between gender and clinical endpoints of cardiopulmonary function. RESULTS: Mean age was 15.2 years, 19% were female, 98% were white. Pectus indices included median Haller Index (HI) of 4.8, mean depression index (DI) of 0.63, correction index (CI) of 33.6%, and Cardiac Compression Index (CCI) of 2.79. Cardiac assessment revealed decreased right and left ventricular ejection fraction (RVEF, LVEF) in 16% and 22% of patients, respectively. PFTs and CPETs were abnormal in ~ 30% of patients. While females had deeper PE deformities-represented by higher pectus indices-they had superior function with higher RVEF, LVEF Z-scores, FEV1, VO2 max, O2 pulse, work, and breathing reserve (p < 0.05). CONCLUSION: Despite worse PE deformity and symptomatology, females had a better cardiopulmonary function and exercise tolerance than males. Further research is needed to assess the precise mechanisms of this phenomenon and postoperative outcomes in this population.

Influence of posture, sex, and age on breathing pattern and chest wall motion in healthy subjects.

OBJECTIVE: We evaluated the effects of posture, sex, and age on breathing pattern and chest wall motion during quiet breathing in healthy participants. METHODS: Eighty-three participants aged 42.72 (SD=21.74) years presenting normal pulmonary function were evaluated by optoelectronic plethysmography in the seated, inclined (with 45° of trunk inclination), and supine positions. This method allowed to assess the chest wall in a three dimensional way considering the chest wall as three compartments: pulmonary rib cage, abdominal rib cage and abdomen. RESULTS: Posture influenced all variables of breathing pattern and chest wall motion, except respiratory rate and duty cycle. Chest wall tidal volume and minute ventilation were reduced (p<0.05) in both sexes from seated to inclined and from seated to supine positions, mainly in males. Moreover, moving from seated to supine position significantly increased the percentage contribution of the abdomen to the tidal volume in both sexes (p<0.0001). Regarding sex, women showed higher contribution of thoracic compartment compared to men (p=0.008). Aging provided reductions on rib cage contributions to tidal volume that were compensated by increases of abdomen contributions (p<0.0001). In addition, increases in end-inspiratory and end-expiratory volumes over the years were observed. CONCLUSION: The degree of contribution of chest wall compartments is dependent on posture, sex, and age. Therefore, verticalization increases expansion of pulmonary rib cage as well as horizontalization increases abdominal displacement. Women presented higher thoracic contribution to tidal volume than men. Aging reduces rib cage contributions to tidal volume that were compensated by increases of abdomen contributions.

Impact of moderate-severe persistent allergic rhinitis on thoraco-abdominal kinematics and respiratory muscle function.

Objective: To assess thoraco-abdominal kinematics, respiratory muscle strength and electromyographic activity of the diaphragm (EAdi) in moderate-severe allergic rhinitis (AR) patients. Methods: A cross-sectional study involving 40 individuals (20 in the AR group) and 20 in the control group [CG]) was conducted. Ventilatory pattern and chest wall volume distribution (optoelectronic plethysmography), respiratory muscle strength (manovacuometry and sniff nasal inspiratory pressure [SNIP]), and EAdi were assessed in both groups. Results: The AR patients had impaired thoraco-abdominal kinematics (reduced total chest wall volume) (p = 0.004), lower values of total respiratory cycle time (p = 0.014) and expiratory time (p = 0.006). They also presented an increase of percentage contribution of the abdominal rib cage (p = 0.475) and respiratory rate (p = 0.019). A positive correlation among pulmonary rib cage tidal volume and MIP (r = 0.544; p < 0.001), SNIP (r = 0.615; p < 0.001), and MEP (r = 0.604; p < 0.001) was observed. After adjusting for age, BMI and gender through multivariate analysis, the individuals with AR presented lower values ​​of MIP (ß = -24.341; p < 0.001), MEP (ß = -0.277; p < 0.001), SNIP (ß = -34.687; p < 0.001) and RMS (ß = -0.041; p = 0.017). Conclusions: The individuals with moderate-severe persistent AR had worse respiratory muscle strength, diaphragm activation and chest wall volume distribution with a higher abdominal contribution to tidal volume than the control group. These findings reinforce the notion that the upper and lower airways work in an integrated and synergistic manner.

Postoperative respiratory muscle training in addition to chest physiotherapy after pulmonary resection: A randomized controlled study.

Purpose: The effects of preoperative respiratory muscle training (RMT) on postoperative complications in patients with pulmonary resection have recently attracted the attention of researchers. More studies are obviously needed to clarify the effects of RMT after pulmonary resection. The aim of this study was to evaluate the effectiveness of intense RMT in addition to chest physiotherapy after pulmonary resection in terms of respiratory muscle strength, exercise capacity, and length of hospital stay rather than postoperative complications. Methods: Forty subjects undergoing pulmonary resection were included in the study. Subjects were divided into two groups using a simple randomization method. The subjects in the study group (SG; n = 20) received RMT in addition to regular chest physiotherapy in the postoperative period. The subjects in the control group (CG; n = 20) received only regular chest physiotherapy. Respiratory muscle strength (maximal inspiratory and expiratory pressure [PImax and PEmax]) was measured pre-postoperatively and before discharge, and exercise capacity, which was measured by the 6-min walk test (6MWT), was assessed preoperatively and before discharge. The length of hospital stay was also recorded. Results: There were no differences between groups in terms of demographic and surgical characteristics. The nonsignificant change of PImax from the preoperative to the discharge value was 65.1 ± 15.5 to 68.2 ± 19.2 cmH2O in SG and 59.2 ± 13.7 to 44.3 ± 14.8 cmH2O in CG (p > 0.05, p > 0.05, respectively). The change of PEmax from the preoperative to the discharge value was 80.4 ± 24.9 to 81.5 ± 24.9 cmH2O in SG (nonsignificant) and 85.4 ± 38.2 to 61.3 ± 25.4 cmH2O in CG (p > 0.05, p = 0.002, respectively). There was a significant difference between SG and CG in terms of RMT effect (PImax: 11.05 [21.84; 0.25] cmH2O p = 0.045; PEmax: 25.23 [42.83; 7.62] cmH2O p = 0.006). A significant difference was found in the 6MWT when the mean differences were compared between the groups (85.72 [166.15; 5.28] m p = 0.037). The length of hospital stay was significantly shorter in the SG (number of days for SG 9.1 ± 3 and for CG 12.9 ± 4.2 [p = 0.002]). Conclusion: The addition of RMT to chest physiotherapy after pulmonary resection can have positive effects on respiratory muscle strength, exercise capacity, and length of hospital stay.
