PURPOSE: The present study examines how feedback respiratory exercise affects gait performance of stroke patients. METHODS: Forty stroke patients were randomly divided into an experiment group and a control group. For the former group, patients went through a half-hour of training therapy and a half-hour of feedback respiratory device exercise. For the latter group, patients went through 30 minutes of training therapy and a half-hour of motomed exercise. All participants had five training sessions each week for four weeks. For measurement, a GAITRite system was used to examine spatial parameters, and functional ambulation performance before and after the training. RESULT: In terms of spatial parameters, double support ratio, stance phase increased significantly in the experiment group after the walking exercise(p<.05). FAP rose more significantly in the experiment group than in the control group(p<.05). In comparison of two exercise groups, double support ratio, Stance phase, gait velocity, FAP was significant difference(p<.05).

Cerebral palsy children represent abnormal vocalization pattern caused by respiration problem and paralyzed oral motor muscle that are the basics of speech production. Thus, this study examined the effect of respiration and articulator training programs on the basic ability of speech production in CP children. The subjects of this study were 4 children with 3 of spastic CP and 1 of ataxia CP. The respiration and articulator program was conducted in 30 sessions for 30 minutes each. Pre-test was administered twice before the program, ongoing test was administered every 5 session during the period of experiment, and post-test was administered twice. The program included speech production such as respiration training, lips, jaw, cheek, and tongue exercise, and velopharyngeal training, and related articulator training. The following results were obtained. First, all subject children were less than 5 seconds in maximum phonation time before the experiment and 2 were improved by more than 4$\sim$5 seconds during the experiment, but 2 had relatively low rising width. Second, while children with less than 30dB before the experiment became bigger in strength during the experiment, children with more than 35dB before the experiment showed a minor change. Subject child 4 had lower vocal strength in the post-test period. Finally, although each subject had individual difference in syllable diadochokinetic ability, the function was improved and the number of repetition in one respiration was also increased.

PURPOSE: This study attempts to examine the impact of respiratory muscle exercises on the respiratory function and quality of sleep among stroke patients. METHODS: A total of 20 stroke patients were randomly divided into a breathing-exercise training group(n=10) and a breathing-device-training group(n=10). Changes in pulmonary function, as well as the quality, were measured before and after the intervention. The breathing exercise was performed three times a week for a total of eight weeks. Breathing-device exercises made use of a lung-capacity-strengthening device and were performed for three times a week for eight weeks. One Flow FVC was used as a measurement tool for the pulmonary function test. The Pittsburgh Sleep Quality Index(PSQI) and a sleep measurement tool were used for sleep evaluation. RESULTS: In a comparison of changes in pulmonary function before and after the training, the breathing-exercise group and the breathing-device-training group showed a significant difference. In changes of sleeping measure and PSQI, the breathing-exercise group and the breathing-device-training group also showed significant differences. CONCLUSION: Diverse index analyses confirmed that breathing exercises and exercises using a lung-capacity-strengthening device, were effective in improving respiratory function and quality of sleep among stroke patients experiencing respiratory function disorders and sleep disorders.

Purpose: The purpose of the study was to assess the effects of proprioceptive neuromuscular facilitation (PNF) training and respiratory muscle endurance training on pulmonary function and activity in chronic stroke patients. Methods: The participants were 25 chronic stroke patients. They were assigned to two groups: a PNF and respiratory muscle training group (experimental group; n = 12) and a conservative training group (control group; n = 13). The experimental group completed 50 minutes (30 minutes of conventional physical therapy, 10 minutes of PNF training, and 10 minutes of respiratory muscle endurance training). The control group also completed 50 minutes (30 minutes of conventional physical therapy and 20 minutes on a full-body workout machine). Pulmonary function and activity were measured before and after the intervention, using Cosmed to analyze pulmonary function and 6MWT as clinical evaluation indicators. Results: Both groups showed significant within-group differences on all tests before and after the intervention; the experimental group showed greater improvement on all tests. Conclusion: The findings confirm that PNF training and respiratory muscle endurance training have a positive effect on pulmonary function and activity index in chronic stroke patients.

This study attempted to compare acoustic parameters, physiological observation and perceptual evaluation values obtained from the treatment and control groups in order to find out which of the self voice feedback therapies was better and which methods to train them were more effective. The experimental group carried out various self voice feedback therapies while the control group did only vocal hygiene. The acoustic measurement and voice manipulation for providing the patients visual, auditory feedback were done by a speech analysis software, Praat. The authors designed vocal hygiene, abdominal respiration and Praat self voice feedback therapies and applied them to 15 patients while applying only one vocal hygiene to 15 of the control group. For the purpose of examining the degree of their voice improvement after the treatment, pre- mid- and final evaluations were made for the two groups at the beginning, the 6th week and immediately after the 8th treatment session. Results of this study were as follows: The treatment group showed much improvement after receiving the voice treatment. In particular, acoustical and physiological indices from the optical endoscopy, pitch variation(Jitter), amplitude variation (Shimmer), maximum phonation time(MPT), and psychoacoustic evaluation showed statistically significant improvements over the control groups.
