Purpose : The purpose of this study was to determine the influence of the elastic-band exercise program for elderly who over 65 years old in terms of depression and physical self efficacy. We aim to suggest interventions with an elastic-band exercise program for elderly. Methods : The study subjects selected were females or males 65 years old or more who could walk without assistance and could talk about daily living without mental or physical disorders. A total of eight subjects understood the purpose of this study and agreed to participate. Before and after the exercise program, the subjects were monitored for changes in their physical self-efficacy and depression. To measure the physical self-efficacy, we used a perceived physical ability scale and physical self-presentation confidence scale (Cronbach α =0.942). To measure depression, we used the geriatric depression scale short form (Korea version, Cronbach α =0.969). The data obtained from each measure were analyzed using the Wilcoxon signed rank test to determine changes from before and after the exercise program. The program consisted of three parts (warm-up, main exercise and cool-down) and included the upper extremities, the lower extremities and trunk exercises with an elastic band (yellow and red). The program lasted for 15 weeks, once a week, with each session lasting for 60 minutes. Results : After 15 weeks of the elastic-band exercise program, there was a significant decrease on the depression scale (p<0.05) and significant improvements on the physical self-efficacy scale (p<0.05). Conclusion : Based upon our results, we demonstrated that the exercise program using the elastic band was effective in improving the depression and physical self-efficacy of the elderly.

PURPOSE: This study was examined the effects of aerobic exercise using a step box and lower extremity strengthening exercise with an elastic band on the balance ability and lower extremity muscular strength in elderly subjects. METHODS: Forty-one healthy adults were randomly divided into experimental group 1 (Exp 1, n=14), experimental group 2 (Exp 2, n=14), and a control group (n=13). The Exp 1 conducted lower limb strengthening exercise using an elastic band and the Exp 2 performed aerobic exercise with a step box 50 minutes per day, twice per week, for eight weeks. RESULTS: There was significant increase in the Exp 1 and Exp 2 in comparison of the change of lower limb muscle strength according to measurement time (p<.05). But there was no significant difference according to intervention methods. In one-leg standing test change among the three groups after the intervention, the Exp 1 and Exp 2 saw significant improvement compared to the control group (p<.05) but there was no significant difference according to intervention methods. The change of the functional reaching test results, the Exp 1 and Exp 2 saw significant improvement according to the time of measurement. In the change of the Timed Up and Go test, there was significant improvement in the Exp 1 and Exp 2 compared to the control group (p<.01), but there was no significant difference according to intervention methods. CONCLUSION: Exercise to lower extremity strengthening program accompanied with aerobic exercise is considered more effective in dynamical balance and ability to walk.

PURPOSE: The purpose of this study was to investigate whether a circuit aerobic exercise program positively affects pulmonary function and gait endurance in chronic stroke patients. METHODS: Twenty-four chronic stroke patients were allocated equally and randomly to an experimental group (n=12) or a control group (n=12). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally performed a circuit aerobic exercise for 30 minutes, while the control group additionally performed a general aerobic exercise, i.e., gait training on the treadmill for 30 minutes. These 30-minute exercise sessions were held three times per week for six weeks. Pulmonary function was assessed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV), and gait endurance was assessed using the 6-minute walk test (6MWT). RESULTS: In the both groups, FVC, FEV1, MVV, and 6MWT were significantly increased after training. Members of the experimental group showed significant improvements in FVC, FEV1, and MVV, and significantly greater improvements than controls (p<.05). However, 6MWT improvements were not significantly different in the two groups (p>.05). CONCLUSION: The devised circuit aerobic exercise program offers an effective rehabilitation aerobic exercise for improving pulmonary function and gait endurance in patients after chronic stroke.

Purpose : The purpose of this study was to investigate the effect of abdominal muscle strengthening exercise on abdominal muscle strength and respiratory function in stroke patients. Methods : The subjects were 14 stroke patients (10 males, 4 females) hospitalized at W rehabilitation hospital in Busan City and randomly assigned to 7 exercise groups and 7 control groups. Exercise was performed in combination with an upper and lower extremity pattern of proprioceptive neuromuscular facilitation. Measurements of abdominal muscle strength and respiratory function were made before intervention and 4 weeks after intervention. Abdominal muscle strength was assessed using a digital manual dynamometer, and respiratory function was assessed by spirometry. The collected data were analyzed with a paired t-test and independent t-test and the significance level was set as α =.05. Results : The results showed that applying abdominal muscle strengthening exercise to stroke patients showed a significant increase in abdominal muscle strength and a significant difference between groups (p<.05). Maximal-effort expiratory spirogram (MES) readings were significantly increased in forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁), in the exercise group, and there were a significant differences between the groups in terms of FEV1 (p<.05). Slow vital capacity (SVC) was significantly increased in vital capacity (VC), tidal volume (TV), inspiratory reserve volume (IRV), and expiratory capacity (EC), and there were significant differences between the groups in VC, TV, expiratory reserve volume (ERV), EC, and inspiratory capacity (IC) (p<.05). Conclusion : Abdominal muscle strengthening exercise was effective in the abdominal muscle strength of stroke patients, and it was confirmed to have a positive effect on the enhancement of respiratory function. Therefore, it seems that exercise programs for stroke patients with respiratory weakness should include abdominal muscle strengthening exercises.

Objectives This study is to review the effectiveness of exercise after lung cancer surgery. Methods Relevant randomized controlled trials (RCTs) were searched in PubMed database. The systematic review was conducted through flow diagram. The risk of biases were assessed through the Cochrane guideline. Characteristics and outcomes were extracted from each study. Meta-analyses of forced expiratory volume in one second (FEV1), 6-minute walk test (6MWT), quality of life (QoL), pulmonary complications were conducted. Results 14 RCTs were selected. In meta-analysis, exercise improved FEV1 (mean difference [MD] 0.14; 95% confidence interval [CI] 0.04 to 0.25; p=0.009; I2=55%) and mean change of FEV1 (MD 0.11; 95% CI 0.02 to 0.20; p=0.02; I2=0%). Exercise increased the distance of 6MWT, but there was considerable heterogeneity (MD 45; 95% CI 21.16 to 68.83; p=0.0002, I2=89%). There was no differences in QoL scores by 2 questionnaires (European Organisation for Research and Treatment of Cancer quality of life questionnaire, short form-36). Exercise reduced the duration of hospital stay (MD -3.32; 95% CI -5.27 to -1.36; I2=0%; 2 studies) but not duration of chest tube intubation (MD -1.37; 95% CI -2.81 to 0.06; I2=0%) and incidence of pulmonary complications (pooled risk ratio 0.54; 95% CI 0.23 to 1.30; I2=0%). Conclusions Exercise might reduce the duration of hospital stay after lung surgery. There was not enough evidence to prove improvement of lung function, aerobic capacity, muscle strength, QoL, and decline of pulmonary complications. Low-quality risk of bias, different units or estimation of outcome, different exercise type and duration, heterogeneity among studies make the evidence of effectiveness weak. Future researches are required to redeem these defects.

Background: The objective of this study was to determine whether sensorimotor training using an unstable surface affects dynamic balance and gait function in patients with hemiparesis, and to compare the effect of sensorimotor training with that of cycling exercise. Methods: Two subjects with post-stroke hemiparesis volunteered to participate in this study. Single-subject A-B design with alternating treatment was used for this study. Baseline(A) and intervention(B) phases were performed for 7 and 8 sessions, respectively. Sensorimotor training and cycling exercise were performed for 20 minutes in randomized order. Assessment tools were made by using a step test, timed up and go(TUG) test, and 6-minute walk test(6MWT). Results: Each of the participants improved in all three tests after the two interventions. Participants 1 and 2 showed the improvement for their assessment score after sensorimotor training in the step test by 42.1%(p<.05) and 58%, in the TUG, 31% and 19.5%, and in the 6MWT test, 32.3% and 10.6%(p<.05), respectively. After cycling exercise, participants 1 and 2 also improved in the step test by 32.5% and 53.1%, in the TUG, 27.4% and 18%, and in the 6MWT test, 28.8% and 3%. In statistical analysis between the two interventions, sensorimotor training showed a significant increased values in the step test for participant 1 and the 6MWT for participant 2 as compared with those of cycling exercise. Conclusion: Sensorimotor training and cycling exercise are helpful for improving dynamic balance and gait capacity. Furthermore, sensorimotor training may be more helpful than cycling exercise.

This study was a quasi-experimental study of nonequivalent control group pretest- posttest design to investigate the effect of aerobic walking exercise program on the physical & psychological functions of home stayed stroke patients. The data were collected during the period of May 20th to August 15th, 2001. The subjects for this study were 40 hemiplegic stroke patients with the experimental group consisting of 19 patients and the control group being composed of 21 patients. The patients selected for this study were: (a)living in J city who had been diagnosed with stroke and at home after being discharged from the hospital, (b)suffering from stroke for 6 months to 5 years, (c)without recognition disorder with the MMSE-K score above 25, (d)below 2 on the modified Ashworth scale, (e)free from heart and pulmonary disease (f)able to walk beyond 15 minutes for themselves. The aerobic walking exercise program for the experimental group was aerobic exercise and education and supportive care. The aerobic exercise was 8 weeks' period, three times a week, 35 to 50 minutes a day. And the education and supportive care was consisted of one home visiting and 2 times telephoning a week. The data were analysed by $X^2$-test, paired t-test and unpaired t-test and ANCOVA through SAS/PC program. The results of the study were as follows: 1. There was insignificant difference in the gait length experimental and control group. There was significant difference in the gait speed between the two groups. 2. There was significant difference in the dynamic valance between the two groups. 3. There was significant difference in ADL score between the two groups. 4. There was no significant difference in the depression between the two groups. As shown above, the results of 8 weeks' the aerobic walking exercise program for home stayed stroke patients produced positive effects on gait speed, dynamic valance, ADL score. And this program was expected that it was more effective in different intervention period, verified program. Also it was needed follow study.

Purpose: Patients with total knee arthroplasty (TKA) have impaired balance and movement control. Exercise interventions have not targeted these impairments in this population. This study aimed to investigate the effect of complex balance exercises on unstable ground, on the gait, balance, and daily living ability of patients with total knee arthroplasty. Design: Randomized controlled trial. Methods: The participants consisted of 30 patients placed into two groups of 15 each: a experimental group (complex balance exercise) and a control group (physical therapy exercise). Both group exercise was applied for 3 times a week for 30 minutes for four weeks. Force plate for balance ability and Timed up and go (TUG) test were the primary outcome measures. The secondary outcome measures included 10-m walk test (10MWT) and the daily living ability using the Knee Outcome Survey Activities of Daily Living scale (KOS-ADL). Results: The result of this study showed that the experimental group had a significant difference in TUG and 10MWT than the control group, and balance was significantly different in CEA, CPL, and CAV. There was a significant difference in daily living ability between the experimental and control groups. This study confirms that the physical therapy with complex balance exercise on unstable surfaces has positive effects on balance, gait and daily living ability in patients with total knee arthroplasty. Conclusion: As a result of this study, complex balance exercise on unstable surface was more effective in improvement gait, balance and daily living ability in total knee arthroplasty. From this study, physical therapy with complex balance exercises on unstable ground may be proposed as and effective intervention method for improving gait, balance, and daily living ability in patients with early total knee arthroplasty.
