        Background:Research efforts to improve the pulmonary function of people with limited chest function have focused on the diaphragmatic ability to control breathing pattern. Real-time ultrasonography is appropriate to demonstrate diaphragmatic mechanism during breathing.Objective:The purpose of this study was to investigate the effects of diaphragmatic breathing training using real-time ultrasonographic imaging (RUSI) on the chest function of young females with limited chest mobility.Methods:Twenty-six subjects with limited chest mobility were randomly allocated to the experimental group (EG) and control group (CG) depending on the use of RUSI during diaphragmatic breathing training, with 13 subjects in each group. For both groups, diaphragmatic breathing training was performed for 30-min, including three 10-min sets with a 1-min rest interval. An extra option for the EG was the use of the RUSI during the training. Outcome measures comprised the diaphragmatic excursion range during quiet and deep breathing, pulmonary function (forced vital capacity; FVC, forced expiratory volume in 1-sec; FEV1, tidal volume; TV, and maximal voluntary ventilation; MVV), and chest circumferences at upper, middle, and lower levels.Results:The between-group comparison revealed that the diaphragmatic excursion range during deep breathing, FVC, and middle and lower chest circumferences were greater at post-test and that the changes between the pretest and post-test values were greater in the EG than in the CG (p<.05). In addition, the subjects in the EG showed increased post-test values for all the variables compared with the pretest values, except for TV and MVV (p<.05). In contrast, the subjects in the CG showed significant improvements for the diaphragmatic excursion range during quiet and deep breathings, FVC, FEV1, and middle and lower chest circumferences after the intervention (p<.05).Conclusion:These results indicate that using RUSI during diaphragmatic breathing training might be more beneficial for people with limited chest mobility than when diaphragmatic breathing training is used alone.

        This study aimed to examine whether McConnell taping for deltoid inhibition affects the Electromyographic (EMG) activity of shoulder girdle muscles during arm elevation. Ten young healthy men were randomly assigned to an experimental and control groups of five men each. For the experimental group, we performed taping for deltoid inhibition on the skin over anterior and posterior deltoids with non-elastic specific tape, and sham-taping with non-elastic under-tape for the control group. Surface EMG measurements were performed three times (before, during and after the tapings) at upper and lower trapezius, mid-deltoid, and serratus anterior muscles while elevating dominant aim with loading and unloading conditions. In deltoid inhibition taping group, there were significant differences in EMG activity of mid-deltoid (p<.05) and serratus anterior (p<.05) muscles during arm elevation with loading. During arm elevation without loading, the EMG activity was significantly decreased for MD in the McConnell taping group (p<.05). The findings indicate that deltoid inhibition taping can modify the activation patterns in shoulder girdle muscles as well as in deltoid muscle. in clinical setting. it may be effectively used for the management of patients with shoulder dysfunction.
