PURPOSE: The aim of this study was to examine the effect of air stacking exercise on lung capacity, activities of daily living, and walking ability in elderly adults. METHODS: A total of 27 subjects were randomly assigned to an experimental group (EG=13) or a control group (CG=14). Subjects in the experimental group participated in an active pulmonary rehabilitation program. 5 days a week for 4 weeks. The active pulmonary rehabilitation program was composed of an air stacking exercise with an oral nasal mask and manually assisted coughing. Conventional pulmonary rehabilitation exercises, such as, cough exercise, deep breathing, and abdominal muscle strengthening exercises were performed by both groups. Pulmonary function parameters, peak cough flow (PCF), and oxygen saturation were measured and the 6-minute walk test and Korean version of the modified Barthel index (K-MBI) scores were applied. RESULTS: Significant intergroup differences were observed for forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) results after intervention (p<.05), and for 6 minute walk test and PCF results after intervention and at 2-week follow-up visits (p<.05). Post hoc test results showed significant differences in K-MBI, 6-minute walk test, and FEV1 in the experimental group after intervention (p<.05). FVC values were significantly higher after intervention and at 2-week follow-up visits versus pre-intervention (p<.05). PCF values were also significantly higher after intervention and remained significantly higher at 2-week follow-up visits (p<.05). CONCLUSION: Air stacking exercise in elderly adults improves lung capacity and exercise tolerance.

The purpose of this study was to apply the joint mobilization technique to the level of segments with pain and to the level of segments with hypomobility respectively and compare the immediate effects of the joint mobilization technique on the pain, the active cervical range of motion (ROM), and treatment satisfaction of patients with acute mechanical neck pain. After the baseline assessment, forty-two patients were randomized into two groups: a painful group ($n_1=21$) that received joint mobilization at the most painful cervical spine level and a hypomobile group ($n_2=21$) that received joint mobilization at the most hypomobile cervical level. The patients received an intervention that applied unilateral posterior-anterior gliding for 5 minutes and two repetitions of 10 times of active extension motion with distraction. In the Wilcoxon signed-rank test, the painful group and the hypomobile group were improved significantly in all pain variables (p<.001), while the painful group was improved significantly in the active cervical flexion (p<.001), extension (p<.001), left side-bending (p<.01), right side-bending (p=.001), left rotation (p<.001), and right rotation (p<.001). The hypomobile group was significantly improved in active cervical flexion (p=.001), extension (p<.001), left side-bending (p<.05), right side-bending (p=.001), left rotation (p=.001), and right rotation (p<.01) after intervention. In the Mann-Whitney U test, there was no significant difference in any of the dependent variables after the intervention between the two groups, but the painful group was slightly superior to the hypomobile group in all variables except for the right lateral flexion ROM and treatment satisfaction. These outcomes suggest that the cervical joint mobilization may be applied to either the level of painful segments or the hypomobile segments for the treatment of patients with acute mechanical neck pain.

Background: The purpose is to investigate the immediate effects of kinesio taping on quadriceps induced fatigue by short-term squat. Methods: This research is cross-over designed study and conducted as a single-blind. Eleven students (Age: $18.91{\pm}0.49yrs$, height: $167.09{\pm}8.46cm$, $62.55{\pm}11.32kg$) were participated in this study. All the participants were applied short-term squat for inducing fatigue, and then intervented all three conditions (kinesio taping applied condition, placebo taping applied condition, non-taping applied condition). The interval of each intervention was at least a seven days to prevent carry-over effects. The participants were tested peak torque (isometric contracture) and active joint position sense (active JPS) pre-post intervention. A paired t-test was used to find the significance of pre-post intervention results and one-way ANOVA was used to find the significance between interventions with significant level as .05. Results: Peak torque was significantly increased on KT condition (p<.05). But there were no significant effects on active JPS. Because kinesio taping facilitates Ia afferent by tactile stimulation with stretched skin, reduced muscle power by short term squat which induce muscle fatigue was increased. But kinesio taping does not affect mechanoreceptor in muscles, induced active JPS by short-term squat had no changes.

We have developed an active front steering system(AFS) with a planetary gear train, which can vary the steering gear ratio according to the vehicle speed and improve vehicle stability by superimposing steering angle. We conducted vehicle tests showing that co-operated control of AFS with ESP can improve vehicle stability by direct control of tire slip angle and that steering reaction torque during AFS intervention can be compensated by torque compensation using electric power steering.

This case report describes the effectiveness of cervical corrective exercises in a patient with cervical radiculopathy (CR) who experienced radicular pain, upper limb paresis, and limited functional activity. A 39-year-old male with cervical radiculopathy performed the cervical corrective exercises for reducing pain. Pain intensity, cervical posture, and active range of motion of cervical intersegmental spine motion were measured baseline, after 4 weeks, and after 8 weeks with self-reported questionnaire and radiographs. After 8 weeks of intervention, the patient demonstrated alleviated radicular symptoms, improved neck posture and active range of flexion and extension of the cervical intersegmental spine. Especially in the angle between the cervical vertebra 6 and 7, the angle was changed from $-4.69^{\circ}$ to $3.30^{\circ}$ during resting position after intervention. The present case indicates that the cervical corrective exercises might be a possible treatment to effectively reduce radicular symptoms, improve neck posture, and active cervical intersegmental motion for patient with CR.

PURPOSE: Hamstring muscle shortening is related to low back pain, and it is important to check the hamstring muscle flexibility and pelvic mobility to analyze the effects of the intervention. This study examined the effects of hamstring muscle shortening on flexibility and pelvic mobility according to the method of stretching the hamstring muscle in patients with low back pain. METHODS: Forty Low Back Pain Patients participated. The subjects performed the Visual Analogue Scale (VAS), Fear Avoidance Belief Questionnaire (FABQ), Korean version of Oswestry Disability Index (KODI), Myovision, and sensbalance therapy cushion (pelvic mobility, proprioception). The subjects were divided into two groups to perform the passive and active stretching protocol. The intervention was conducted three times a week for four weeks. RESULTS: Hamstring muscle flexibility was increased significantly in both groups (p < .05), and there was no difference between the groups. VAS, FABQ was decreased significantly in both groups (p < .01), and there was no difference between the groups. The left lower back muscle impedance was decreased significantly in both groups (p < .05). The passive stretching group showed a significant increase in the pelvic anterior, posterior, and left tilt ROM (p < .05). The active stretching group showed a significant increase in the pelvic anterior, posterior tilt ROM (p < .05). CONCLUSION: Both stretching methods may be useful intervention methods for pelvic mobility and pain recovery and can assess back pain recovery.

Background: Various interventions have been tested to prevent or treat childhood obesity in South Korea. However, the overall effect of those interventions is unclear, as very few reviews and meta-analyses were specific to Korean children and adolescents. Purpose: We aimed to examine the overall effect of obesity interventions among Korean children and adolescents, while also examining differences by sex, age group, baseline weight category, intervention duration, number of intervention components, and type of intervention components. Methods: A meta-analysis was conducted for all intervention studies sampling Korean children and adolescents, with at least one control group and one month of follow-up, published between January 2000 and August 2020. Cohen d was calculated as an effect size for treatment effect, using the standardized difference between intervention group's body mass index (BMI) change and control group's BMI change. Results: The final sample included 19 intervention studies with 2,140 Korean children (mean age, 12.2 years). Overall, interventions were strongly favored over their controls (d=1.61; 95% confidence interval [CI], 1.12-2.09). The subgroup analysis showed that interventions with at least one physical activity component (d=2.43; 95% CI, 1.63-3.24) were significantly better than those that did not include physical activity (d=0.02; 95% CI, -0.26 to 0.31). Conclusion: Type of intervention component appeared important, though no differential association was observed by sex, age, baseline weight category, intervention duration, and number of intervention components. Korean and non-Korean interventions may be substantively different. Additional studies are needed to understand why and how Korean interventions differ from non-Korean interventions.
