“…Lung function is generally determined by respiratory muscle strength, chest compliance, airway resistance, and elastic recoil of the lung. FVC (forced vital capacity refers to the maximum amount of air that can be exhaled as soon as possible after trying to inhale), FEV1.0 (expiratory volume in the first second of starting exhalation), FEV1/FVC% (an important index to judge pulmonary ventilation function, the normal value is 83%), MIP and MEP are commonly used to evaluate pulmonary function in patients with AIS [ 17 ]. Most scholars have found that FVC, FEV1, MIP, and MEP of AIS patients are significantly lower than those of healthy adolescents [ 18 , 19 ].…”

Objective. To observe the effects of core stabilization training on the Cobb angle, respiratory muscle strength (maximum inspiratory pressure, MIP; maximal expiratory pressure, MEP), and pulmonary function (forced vital capacity, FVC; forced expiratory volume, FEV1.0; FEV1.0/FVC%) in adolescent patients with idiopathic scoliosis (AIS) and offer practical-based evidence for the rehabilitation treatment for AIS patients. Methods. 36 AIS patients were assigned to the core stability training (CST) group (n = 18) and control group (n = 18); the CST group participated in three sessions of core stabilization exercise per week for 12 weeks and the control group did not perform regular physical training during 12 weeks of study. Then, the Cobb angle, respiratory muscle strength (MIP and MEP), and pulmonary function (FVC, FEV1.0, and FEV1.0/FVC%) were measured before and after core stabilization training. Results. After 12 weeks of core stabilization training, compared with the pretest, the Cobb angle showed a significant decrease, FVC, FEV1, MIP, and MEP a significant increase ( P < 0.01 respectively), and there was no statistical difference in FEV1/FVC in the CST group; there was no significant difference ( P > 0.05 respectively) before and after an experiment in the control group except MEP decreased significantly ( P < 0.01 , P < 0.05 ). After 12 weeks of core stabilization training, compared with the control group, the Cobb angle significantly decreased ( P < 0.01 ), FVC, FEV1, MIP, and MEP significantly increased ( P < 0.05 respectively) in the CST group, but there was no significant difference ( P > 0.05 , respectively) in FEV1/FVC between the control group and CST group. Conclusions. Core stabilization exercise can be considered to have a positive effect on the normal physiological curvature of the spine in AIS patients, as it decreases the Cobb angle and strengthens respiratory muscle strength and pulmonary function.

“…MVV is also closely correlated with the Cobb angle, which is the most widely used measurement to quantify the magnitude of spinal deformities. It was reported that this is a more practical and sensitive test than FVC for assessing adolescent patients with idiopathic scoliosis [ 12 ]. In this study, MVV showed remarkable short-term and long-term improvements.…”

“…The chest expansion test was selected to test the mobility of the rib cage [ 12 , 13 ]. While in a seated position, the patient was asked to breathe in gradually through the nose, using lung expansion to push the measuring tape as much as possible, then to breathe out through the mouth as completely as possible.…”

Background: Vertebral compression fractures (VCFs) often occur in patients with osteoporosis. These fractures can also lead to postural changes. Several studies have shown that patients with vertebral compression fractures have a restrictive pattern in their pulmonary function. Percutaneous vertebroplasty (PVP) is the standard treatment for vertebral compression fractures, with the benefits of pain relief and enhancement of vertebral stability for partially collapsed vertebral bodies. However, the effects of PVP on short-term recovery of respiratory performance have not been investigated. Therefore, this study aimed to investigate the changes in pulmonary function, respiratory muscle strength, maximal voluntary ventilation (MVV), and chest mobility in patients with vertebral compression fractures after PVP. Methods: This research was approved by the clinic committee of the E-DA Hospital Institutional Review Board (EMRP07109N) and registered in the Thai Clinical Trials Registry (TCTR20211029005). We recruited 32 VCF patients. Four-time points were measured: before and after PVP and 1 and 3 weeks after PVP. We measured pulmonary function and maximum voluntary ventilation (MVV) by using spirometry. Respiratory muscle strength was assessed by using a respiratory pressure meter. The chest expansion test was used to evaluate chest mobility. A visual analogue scale (VAS) was used to assess resting and aggravated back pain. Results: Chest expansion and back pain improved at each time point after PVP. MVV showed significant progress at both 1 and 3 weeks after discharge. Forced expiratory volume in 1 second (FEV1) and maximal inspiratory muscle strength significantly improved 1 week after discharge. Conclusion: Taking all the data together, PVP not only can resolve severe back pain but can also provide excellent improvements in MVV and chest mobility in patients with vertebral compression fractures.

“…Some studies have analyzed AIS patients with pulmonary impairments 16 and have demonstrated a weak negative correlation between curve severity and pulmonary function. 5,[20][21][22] Vitale et al 23 found that the degree of the thoracic curve was negatively correlated with FEV 1 and FVC. Saraiva et al 24 found negative correlations between the main thoracic Cobb angle and PFT, the greater the spine deformity, the worse the lung function in patients with AIS.…”

Objective: The objective of the study was to evaluate the spinal and extraspinal factors responsible for pulmonary dysfunction in adolescent idiopathic scoliosis patients.Summary of Background Data: Development of thoracic deformity due to scoliosis results with the restrictive ventilatory pattern and the reduced pulmonary function. To prevent pulmonary function deterioration, it is imperative to understand which factors are causing the restrictive lung disease in adolescent idiopathic scoliosis patients.Materials and Methods: An online database search was conducted in a hospital computerized archive between 2008 and 2018 years. Cobb angle of > 30 degrees, Lenke type 1 and 2 patients treated in a single spine unit were included. Coronal and sagittal Cobb angle, bending correction rate for evaluation of flexibility, Risser score, apical vertebra rotation (AVR), and pulmonary function test of patients were obtained.Results: There was a moderate negative correlation between forced expiratory volume in the first second, forced vital capacity, and AVR. There was no correlation between forced expiratory volume in the first second and forced vital capacity with age, sex, Cobb angle, Risser score, kyphosis, and bending correction rate.Conclusions: When considering the results of the current study and the other studies in the literature there is not any strong correlation between the features of scoliotic curvature and respiratory functions. In the current study, 52 (72.22%) of 72 patients with moderate to severe scoliosis had mild to severe respiratory dysfunction. Considering the age-related physiological respiratory loss, to evaluate the necessity of surgical treatment in patients with moderate and severe scoliosis, especially in patients with high AVR, the respiratory functions of the patient should also be evaluated.
