“…In a previous studie was observed in AIS patients at the preoperative period ISWD of 69 meters less than that observed in our study. 7 The authors also observed higher VO 2 (1247 ± 450 ml/min) and lower ISWD (498 ± 144 m) when compared to our study. The patients in the LPO period in the present study presented lower VO 2 obtained in a higher ISWD.…”

“…AIS patients had on average 24 ± 9 months of postoperative and the number of fixed vertebrae was 8. [7][8][9][10][11] No significant differences were observed between groups regarding anthropometric characteristics ( Table 1). The absolute and predicted values of FVC and FEV 1 were, on average, significantly lower in the SG ( Table 2).…”

“…This has already been demonstrated with a significant reduction in oxygen consumption (VO 2 ) in Cardiopulmonary Exercise Testing (CPET). [4][5][6] Few studys used the Incremental Shuttle Walking Test (ISWT) to evaluate exercise limitation in this population, 3,7,8 but only in patients during the preoperative period. The ISWT is a simple walking test, which shows good reproducibility, no need to use specific ergometer 9,10 and it can be done with good tolerance and safety in children and adolescents.…”

Introduction: Patients with Adolescent Idiopathic Scoliosis (AIS) show reduced exercise capacity during the Incremental Shuttle Walk Test (ISWT). However, we not know how patients behave in the late postoperative (LPO) period. Objective: The aim of this study was to evaluate the ISWT distance (ISWTD) and physiological responses during ISWT in AIS patients during the LPO period. Methods: We included 22 patients with AIS in the LPO period (SG) and 21 adolescents in the Control Group (CG). We assessed pulmonary function (FVC and FEV1). During ISWT, a gas analyzer was used to assess peak oxygen (VO2) and submaximal relations: Oxygen Uptake Efficiency Slope (OUES) and the breathing pattern (ΔVT/ΔlnVE). Results: Significantly lower values were observed in SG: VO2 (22 ± 5 vs. 27 ± 4), ISWTD (567 ± 94 vs.604 ± 86), FVC (2.70 ± 0.47 vs. 3.33 ± 0.52) and FEV1 (2.41 ± 0.46 vs. 2.84 ± 0.52). There were significant correlations between ISWTD and VO2/Kg (r = 0.80); between OUES and ΔVT/ΔlnVE (r = 0.65); and between the main thoracic curve with VO2/Kg (r= −0.61). Conclusion: AIS patients in the LPO period have significantly reduced exercise capacity associated with reduced lung function, residual spinal curve and cardiovascular deconditioning.

“…Other studies have compared the exercise capacity of AIS patients and non-affected individuals, however, they used the six-minute walk test [5] or cycle ergometer test [11,12,20]. Few studies used the ISWT to assess aerobic capacity in this population [21], but they did not assess the influence of the thoracic deformity on exercise variables.…”

Introduction: The spine deformity due to adolescent idiopathic scoliosis (AIS) generates respiratory mechanical limitations that may reduce the physical activity performance. Objective: To evaluate the thoracic deformity, exercise capacity and lung function in AIS patients comparing to healthy adolescentes. Besides investigating associations between thoracic deformity and exercise capacity in AIS patients. Methods: Thirty-two AIS patients and 22 healthy adolescents underwent chest wall evaluation by photogrammetry. We created thoracic markers shaped as angles (A): A3 (xiphoid process and the last false rib on the right and left sides) and A5E (inframamilar / inferior angle of the scapula / left acromion). Individuals were submitted to incremental shuttle walk test (ISWT) and physiological responses were quantified: oxygen consumption (VO2), tidal volume (VT), minute ventilation (VE), the rate of gas exchange (R) and the walked distance (ISWD). Pulmonary function test was performed and the forced vital capacity (FVC) and expiratory volume in first second (FEV1) were obtained. Results: Patients with AIS presented FVC (p = 0.015), FEV1 (p = 0.044), VO2 (p = 0.015), VO2/kg (p = 0.008), VT (p < 0.001), VE (p = 0,010) and ISWD significantly reduced compared to healthy adolescents. We found moderate correlations

“…A steeper increase in ΔVE/ΔVCO2 relationship indicates hyperventilation, increased dead space of breathing, or both. In addition, lower values of ΔVT/ΔlnVE relationship translate a tachypneic breathing pattern (4). To analyze these dynamic relationships properly, a rapidly incremental exercise protocol is required (3).…”

Introduction: Understanding the normal dynamic physiological responses to the incremental shuttle walk test might enhance the interpretation of walking performance in clinical settings. Objective: To assess dynamic physiological responses to the incremental shuttle walk test and its predictors in healthy adults. Methods:We assessed the simultaneous rates of changes of Δoxygen uptake/Δwalking velocity (ΔVO 2 / ΔWV), Δheart rate/Δoxygen uptake (ΔHR/ΔVO 2 ), Δventilation/Δcarbon dioxide production (ΔVE/ΔVCO 2 ), and Δtidal volume/Δlinearized ventilation (ΔVT/ΔlnVE) during the incremental shuttle walk test in 100 men and women older than 40 years. Fat and lean body masses (bioimpedance) were also evaluated. Results: We found that the dynamic relationships were not sex-dependent. Participants aged ≥ 70 presented declines in ΔVO 2 /ΔWV slope compared to those aged 40-49 (215 ± 69 vs. 288 ± 84 mL.min-
