PURPOSE:The aim of this study was to investigate the effects of distal movement on shoulder muscle activation during diagonal pattern of exercises. METHODS:Seventeen healthy male participants volunteered to participate. Five muscles of shoulder were investigated during standing performance of diagonal shoulder exercises with and without visual trace. Two patterns of the diagonal exercises were used as diagonal 1 flexion and extension (D1F-E), and diagonal 2 flexion and extension (D2F-E). Two way repeated measures analysis of variance was used, which the factor was the presence of distal movement and exercise variations. RESULTS:The average muscle activity values of the lower trapezius and anterior deltoid are higher with the D2F-E, compared to the D1F-E (p<.05). The distal movement effect was observed within included all muscles except the lower trapezius, which the values are significantly greater in exercise with distal movement (P<.05). All significant increase of the muscles during the exercise with distal movement condition showed over 0.9 for the observed power in present study. CONCLUSION:Present result suggested that the diagonal pattern of exercise with distal movement has additional advantages of activating the scapulothoracic muscle as well as glenohumeral muscles. In addition, the D2F-E exercise pattern is effective for activating lower trapezius and anterior deltoid muscles.

PURPOSE:The purpose of this study was to investigate the effects of ten minutes of manual passive exercise performed by physical therapists on autonomic nervous system. METHODS:Thirty-five healthy adults, both male and female, were chosen as subjects for this study. The autonomic nervous system was measured by heart rate variability (HRV),before and after passive exercise using the following measurements: mean heart rate (mean HRT), low frequency (LF) and high frequency (HF) components, the LF/HF ratio, root mean square of the successive differences (RMSSD), and the HRV index. The exercise was performed on the subjects by a physical therapist with seven years of experience specializing in the nervous system. The exercise was conducted at the mid-range of motion on the upper and lower limbs of the subjects for two minutes and thirty seconds and for a total of ten minutes. RESULTS:There was a significant increase in the LF component. The mean HRT and the LF/HF ratio both increased, but these increases were not significant. The HF component, RMSSD, and HRV index all decreased, but these decreases were not significant. CONCLUSION:In conclusion, mid-range manual passive exercise does not induce stress on the autonomic nervous system. It can safely be performed by a physical therapist.

PURPOSE:This study compared the effects of chest expansion resistance exercise (CERE) and breathing retraining (BRT) on stroke patients’ chest expansion and maximal inspiratory pressure(MIP), thereby intending to present an effective intervention method for enhancing their respiratory functions. METHODS:The subjects were 30 stroke patients and randomly and equally assigned to a CERE group (10), a BRT group (10), and a control group (10). The intervention was applied to each group five times per week, 30 minutes per each time, for six weeks. A tapeline was used to measure upper and lower chest expansion and MIP prior to and after the intervention and the results were compared. RESULTS:After the intervention, the upper and lower chest expansion was considerable in the CERE group (p<.01), significant in the BRT group (p<.05) but was not significant in the control group (p>.05). According to the post-hoc test result, the upper and lower chest of the CERE group and the BRT group significantly expanded compared to that of the control group (p<.05) and the upper and lower chest of the CERE group statistically significantly expanded relative to that of the BRT group (p<.05). According to the MIP evaluation result, the CERE group saw considerable improvement (p<.01) and the BRT group underwent significant changes (p<.05), but there were no significant changes in the control group (p>.05). The post-hoc test result was that the CERE group and the BRT group saw significant improvement compared to the control group (p<.05) and the CERE group experienced statistically significant enhancement relative to the BRT group (p<.05). CONCLUSION:As an intervention for respiratory function improvement, CERE is considered effective for strengthening respiratory muscles and promoting chest expansion through manual resistance by a therapist.
