Sažetak
INTRODUCTION: In asthmatic pharmacological as well as self- management education and -non-pharmacological therapy, respiratory physiotherapy (whole-body exercise training, inspiratory muscle training (IMT) and breathing retraining techniques) has an important role. There is a debate regarding the effectiveness of inspiratory muscle training in asthmatics, with no conclusive evidence to support or refute IMT for asthma. OBJECTIVE: The aim of this study was to evaluate the effects of specific IMT using an individual training device designed to increase the strength and endurance of the inspiratory muscles on pulmonary function, muscle strength and endurance in children with asthma. METHODS: In the randomized clinical study we included 135 children (male=82, aged 6-18 years, mean=12, 6) with mild to moderate asthma diagnosed by a physician, treated in the Children's Hospital Srebrnjak. Hundred and eight children underwent specific IMT by a special physiotherapy device during one month (at least 10 times/month). Twenty seven children were given instructions how to perform diaphragmatic breathing exercises regularly at home during one month. The results were evaluated using Wilcoxon Signed Ranks Test and only values of p<0, 05 were considered statistically significant. RESULTS: The comparative analysis showed that the values of absolute and relative forced vital capacity (FVC_rel and FVC_abs, respectively), absolute peak expiratory flow (PEF_abs), peak expiratory flow measured by a peak flow metar (PFM) and absolute forced expiratory volume in first second (FEV1_abs) have significantly increased in comparison to their initial values in the IMT group: FVC_abs from 2, 93 ± 0, 81 L to 2, 99 ± 0, 83 L (p=0, 012), FVC_rel from 87, 86 ±11, 06 % to 89, 48± 10, 65 % (p=0, 011), PEF_abs from 5, 65 ± 1, 73 L/min to 5, 81 ± 1, 79L/min (p=0, 013), PFM from 324, 35 ± 99, 21 L/min to 341, 78±112, 82 L/min (p=0, 003) and FEV1_abs from2, 54019 ± 0, 734916 to2, 5933 ± 0, 75554 (p=0, 25). On the other hand, the values of FVC_abs, FVC_reland PEF_abshave not shown a significant increase in the group of children who performed breathing exercises at home, although PFMsignificantly increased from 303, 46 ± 94, 27 L/min to 339, 26 ± 75, 74 L/min (p=0, 011).The results also revealed a significant increase of maximal inspiratory pressure (MIP) and inspiratory muscle endurance (Tlim), defined as the time the subject was able to sustain breathing against an inspiratory pressure load equivalent to 60% of the MIP, in both groups. In the IMT group MIP increased from 79, 88 ± 31, 99 cmH₂O to 117, 7±29, 33 cmH₂O (p=0, 000) and Tlim from 259, 74±361, 74 s to 437, 35±413, 28 s (p=0, 000). CONCLUSION: Specific IMT, using an individual training device designed to increase the strength and endurance of the inspiratory muscles, may improve pulmonary function in children withasthma, as indicatedbytheincreaseof FVC, PEF, FEV1, as well as the inspiratory muscle strenght and endurance, as indicated by the increase of MIP and Tlim.
