“…Our sample size (n = 25) was similar to those of other studies carried out on patients with KSCHRF (n = 24 to n = 27) [11,12]. Chest wall compliance decreases with age, and work of breathing and risk of respiratory muscle fatigue further increase in elderly patients [1].…”

“…López-Campos et al [11] and Cejudo et al [12] studied the shuttle walking test (SWT) and maximal cycle ergometry test (CET) to assess the functional capacity in patients with KS-CHRF and disease-specific health-related quality of life (HRQoL). The severity of lung function was similar to that of our sample although their patients were older and less hypercapnic, but those authors did not use the 6MWT.…”

“…Borg scale) [9,10]. However, in few studies were the shuttle walking test or maximal cycle testing used to examine performance in these patients [11,12]. In the present study we aimed to evaluate 6MWD and dyspnea perceptions (modified Borg scale) [13] and cardio-pulmonary function testing in patients with KS-CRF.…”

AimTo evaluate kyphoscoliosis patients with chronic hypercapnic respiratory failure (CHRF) using the six minute walk test (6MWT) distance (6MWD) and cardio-pulmonary function tests.MethodThis prospective cross-sectional study was carried out in a tertiary training and research hospital in Turkey. Kyphoscoliosis patients with CHRF on home mechanical ventilation (HMV) followed in a respiratory intensive care unit (RICU) out-patient clinic were enrolled. Patients' demographics were recorded as well as transthoracic echocardiography (ECHO), 6MWD, spirometry, arterial blood gas (ABG) values and high resolution chest computed tomography. 6MWT results were compared with other parameters.ResultsThirty four patients with kyphoscoliosis and chronic respiratory insufficiency admitted to our outpatient clinic were included in the study but 25 (17 M) patients underwent 6MWT (8 patients walked with oxygen supplement due to PaO2 < 60 mm Hg). The mean 6MWD was 274.4 ± 76.2 (median 270) m and median 6MWD predicted rate was 43.7% (inter quartile ratio, IQR, 37.6% to 47.7%). Median HMV use was 3 years (IQR 2-4). 6MWD predicted rate, body mass index (BMI), HMV duration were similar in male and female patients. 6MWD correlated well with age, BMI, dyspnea score for baseline 6MWT (r: - 0.59, p < 0.002, r: - 0.58, p < 0.003, r: - 0.55, p < 0.005 respectively) but modestly with forced expiratory volume in one second, pulse rate for baseline 6MWT, pulse saturation rate, fatigue and dyspnea score at end of 6MWT (r: - 0.44, p < 0.048; r: 0.44, p < 0.027; r: - 0.43, p < 0.031; r: - 0.42, p < 0.036; r: - 0.42, p < 0.034 respectively). 6MWD predicted rate was only correlated with dyspnea score at baseline (r: - 0.46, p < 0.022). The systolic pulmonary arterial pressure (PAPs) in 6 (24%) cases was more than 40 mmHg, in whom mean PaO2/FiO2 was 301.4 ± 55.4 compared to 280.9 ± 50.2 in those with normal PAPs (p > 0.40).ConclusionThe 6MWT is an easy way to evaluate physical performance limitation in kyphoscoliosis patients with chronic hypercapnic respiratory failure using home mechanical ventilation. Nearly 275 m was the mean distance walked in the 6MWT, but rather than distance in meters, the 6MWD predicted rate according to gender and body mass index equation might be a better way for deciding about physical performance of these patients. Dyspnea score at baseline before the 6MWT may be the most important point that affects 6MWD in this patient population.

“…27 It is noteworthy that the shuttle walk test has been validated to be sensitive to assess functional capacity in patients with KS. 28 Interestingly, the mean shuttle walk distance increase was 67.2 m in the exercise group, which exceeds the 47.5 m that is considered to be the minimum clinically important difference after pulmonary rehabilitation. 29 Part of these increases might account for a learning effect, given the smaller yet nonsignificant increases also observed in the control group, for both tests.…”

BACKGROUND: Research has provided evidence for the safety, feasibility, and efficacy of exercise training in patients with COPD. However, little is known about the impact of exercise training in patients with chronic respiratory failure due to kyphoscoliosis. We evaluated the effect of an exercise training program on exercise capacity, muscle strength, dyspnea, and quality-of-life indices in subjects with chronic respiratory failure due to kyphoscoliosis. METHODS: The 34 subjects were clinically stable, had been receiving nighttime home mechanical ventilation for > 6 months, and were randomly assigned to the exercise group (n ‫؍‬ 17) or the control group (n ‫؍‬ 17). The exercise group conducted cycle and strength training on 3 non-consecutive days per week for 12 weeks. We measured pulmonary function, exercise capacity, peripheral muscle strength, dyspnea scores, and quality of life. RESULTS: Statistical analysis was carried out on the data from 16 subjects in the exercise group and in 11 subjects in the control group. Three of the lung-function parameters in the exercise group significantly changed: P aCO 2 (P ‫؍‬ .04), inspiratory pressure (P ‫؍‬ .03), and expiratory pressure (P ‫؍‬ .04); and endurance time (P ‫؍‬ .002) and shuttle walk distance (P ‫؍‬ .001) increased significantly. The exercise group had significantly greater improvements in peripheral muscle strength, dyspnea, and quality of life. CONCLUSIONS: In patients with chronic respiratory failure due to kyphoscoliosis, exercise training improved exercise capacity, peripheral muscle strength, dyspnea, and quality of life.
