This study was conducted to investigate the effect of the active exercise program using sling on the pain and balance of total knee replacement patients. Subjects were 20 patients who received total knee replacement and are hospitalized, 10 patients in each group were randomly assigned to a group (CPM group) that applied only CPM (Continuous passive motion) and a group (CSG) that combined CPM with a active exercise program using sling. CG was performed CPM 5 days a week, CSG performed CPM 2 days a week and a active exercise program using sling 3 days a week, and each intervention was performed for 40 minutes a day for a total of 4 weeks. Pain was evaluated using VAS (Visual analog scale), and balance was measured using BT4 (Balance training 4) to measure C90 area, trace length, and Sway average velocity with eyes open and closed. As a result, there was a significant decrease in pain in both groups, and there was also a significant difference in the amount of change between groups. In balance, all variables except C90 of CG showed significant changes after intervention, and there was a significant difference between C90 and Vel with eyes closed in the amount of change between groups. Therefore, we believe that CPM and active exercise program using sling are effective interventions to reduce pain and improve balance in total knee replacement patients.

Present study was conducted to investigate the effects of exercise and cholesterol diet on plasma and liver lipids, platelet aggregation, erythrocyte Na efflux and liver index such as GOT and GPT using Sprague Dawley rats. Forty rats were divided into four groups and fed control or 0.5% cholesterol diet with and without treadmill for six weeks. The final body weight of group fed cholesterol diet with exercise was somewhat decreased compared with group fed cholesterol diet without exercise. L.W/B.W ratio was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise tended to decrease this ratio. Plasma total cholesterol was significantly increased and HDL-cholesterol was decreased in groups fed cholesterol diet (p < 0.01). Plasma triglyceride was significantly decreased in groups fed cholesterol diet compared with groups fed control diet (p < 0.01). Plasma triglyceride of groups with exercise was significantly decreased compared with their non exercising counterparts regardless diet (p < 0.05). Liver total cholesterol and triglyceride was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise did not affect on these levels. Na-K ATPase was somewhat decreased in groups fed cholesterol diet, and exercise tended to recover the reduced Na-K ATPase. Na passive transport was significantly decreased in group fed control diet without exercise and significantly increased in group fed cholesterol diet with exercise, there were significant differences between groups (p < 0.05). There were no differences in total Na efflux and intracellular Na among groups, and total Na efflux was not correlated with intracellular Na. Hematocrit was significantly lower (p < 0.05) in group fed cholesterol diet without exercise compared with other groups. Platelet aggregation in the initial slope and the maximum was increased in groups fed cholesterol diet, but not statistically significant. Exercise especially increased the initial slope of aggregation. Plasma GOT and GPT was significantly increased in groups fed cholesterol diet (p < 0.01), and exercise in group fed cholesterol diet significantly decreased both GOT and GPT compared with the non exercising counterpart (p < 0.01). This study showed that cholesterol diet increases plasma and liver lipids and GOT and GPT, and exercise improves plasma and liver lipid profile and liver index of GOT and GPT preventing fatty liver.

Objective: This study was carried out to compare changes in pain, swelling and range of motion (ROM) between the two groups according to physical therapy intervention. Design: Randomized controlled trial. Methods: There were a total of 20 elderly subjects ages 65-75 years old who have been admitted to the hospital for a total knee arthroplasty. After surgery, the experimental group (n=10) carried out quadriceps femoris muscle strengthening exercise, hamstring stretching exercises and gastrocnemius stretching exercise with a physical therapist for 30 minutes and additionally, received ice pack therapy for 20 minutes once a day. The control group (n=10) carried out continuous passive motion for 30 minutes and received ice pack therapy for 20 minutes once a day. The experimental group and control group carried out each intervention program for 2 weeks 3 times a week. The Visual Analogue Scale was used to assess pain, tape measurements were taken to assess swelling, and a steel goniometer was used to assess knee joint ROM. Results: As a result, the experimental group showed a statistically significant decrease in the pain and swelling, and a significant increase in knee flexion ROM after the intervention, compared to the control group (p<0.05). There was a significant improvement in pain, edema, and knee flexion and extension ROM in all subjects after intervention (p<0.05). Conclusions: According the results of this study, exercise in the experimental group is effect on the pain, swelling and ROM for total knee arthroplasty.

Background: This study was to investigate the effect of 8-weeks medical exercise therapy on ankle pain, range of motion, stress symptom after traumatic injury, and depression, in a 51 years old stroke patient with right ankle joint inflammation. Method: The 8-weeks medical exercise therapy program was applied to 4 grades of Dosage 1 (1-3 weeks), Dosage 2 (4-5 weeks), Dosage 3 (6-7 weeks), and Dosage 4 (8 weeks) on right ankle joint inflammation in a female with right hemiplegia admitted to D hospital located in Gyeonggi-do. Result: The findings showed that visual analogue scale (VAS) scores improved from 8 to 0-1 scores, passive range of motion (ROM) increased to 5 degrees more than before, Korean-version impact of event scale-revised (IES-R-K) scores increased from 61 to 31 scores, and Korean-version beck depression inventory II (BDI-II-K) scores decreased from 51 to 17 scores. As such, the 8-week medical exercise therapy program may decrease the pain, increase ROM, improve stress after traumatic injury, and improve depression symptom. Conclusion: The presented evidence suggests that exercise and physical activity have beneficial effects on depression symptoms. It is possible to apply the medical exercise therapy for modulating pain experience and treating pain. Also, it may be effective methods to treat the psychological aspects of pain.

Purpose：The aim of this study was to determine the effect of active sling exercise on shoulder subluxation in hemiplegic patients. Methods：Twenty persons with shoulder subluxation were randomly divided into two groups; the experimental group(10 persons) and the control group(10 persons). Usual physical therapy and occupational therapy were applied in all groups in a day for 4 weeks. Additionally the experimental group was received 30 minutes sling active exercise (flexion, extention, adduction, abduction, intenal rotation, external rotation, horizontal adduction, horizontal abduction) for shoulder joint in a day for 4 weeks. I investigated the therapeutic effect of sling exercise through the Wolf motor function test (WMFT), Quantitative radiographic measurements and range of motion test at pre and post intervention period. Results：The passive range of motion was significantly increased in the experimental group compare with the control group. However, the active range of motion was no statistically significantly difference in both of the experimental and the control group. The level of WMFT was significantly decreased in the experimental group compared with control group. Although, there was no significantly difference the degree of the shoulder subluxation was more decreased in experimental group than control group. Conclusion：Taken together, these results suggest that sling exercise could be beneficial therapeutic method for hemiplegic shoulder. But to generalize it, more study and exercise program might be needed to confirm its availability.

PURPOSE: This study aimed to explore the effect of applying elastic taping and passive stretching exercises simultaneously on the muscle tone of the upper trapezius. METHODS: Thirty healthy adults were randomly divided into two groups: the 'passive stretching exercise' group (n = 15) and the 'passive stretching exercise with elastic taping' group (n = 15). Muscle tone was measured using the MyotonPRO®. The muscle tension was measured immediately after the stretching exercises and taping intervention, and again 5 minutes after the intervention. RESULTS: Within each group, there was a significant reduction in muscle tone in the upper trapezius after treatment (p < .05). However, there was no significant difference in the muscle tone reduction between the groups (p > .05). Both experimental and control groups showed a significant decrease in muscle tone in both the upper trapezius muscles over time, i.e., immediately after treatment and five minutes later (p < .05). The main effect of time was identified in the repeated measures analysis, while there was no main effect attributed to the treatment method (group) (p < .05). CONCLUSION: The simultaneous application of stretching exercises and taping as an intervention to reduce muscle tension in the upper trapezius is still considered challenging and not yet widely regarded as an essential intervention method.

Activeness of exercise is critical for stroke rehabilitation so that application of stimulation in response to patient's intention would be effective in FES cycling. The purpose of this study was to investigate the relationship between muscle reaction force (MRF) and electromyogram (EMG) during cycling exercise, for the future usage of MRF as patients' intention signal. Seven young men ($24{\pm}1.63$ yrs) participated in this study. Cycling speed was set to 20 RPM and 60 RPM. MRF and EMG were measured in the vastus lateralis muscle of right leg. Active cycling was performed at the maximal load (16 Nm) of an ergometer. Angle dependent artifact in MRF was measured from passive cycling and was subtracted from the MRF of active cycling. The delay of MRF with respect to EMG envelope and their correlation coefficients were derived from the best of cross correlation. MRF was significantly correlated with EMG amplitude in all subjects (p<0.01). Their mean correlations were 0.84 and 0.91 for 20 RPM and 60 RPM, respectively. Mean delay in MRF was 59.14 ms and 53.14 ms for 20 RPM and 60 RPM, respectively. The result suggests that MRF can be used to assess patient's intention for exercise as a substitute to EMG. The method may be applied to FES cycling to encourage patient's effort which is critical for stroke rehabilitation.

The purpose of this study was to estimate the potential injury via analyzing ground reaction force components that were resulted from a prolonged-run-induced fatigue. For the present study, passive and active components of the vertical ground reaction force were determined from time and frequency domain. Shear components of GRF also were calculated from time and frequency domain. Twenty subjects with rear foot contact aged 20 to 30, no experience in injuries of the extremities, were requested to run on the instrumented tread-mill for 160 minutes at their preference running speed. GRF signals for 10 strides were collected at 5, 35, 65, 95, 125, and 155 minute during running. In conclusions, there were no significant difference in the magnitude of passive force, impact load rate, frequency of the passive and active components in vertical GRF between running times except the magnitude of active force (p<.05). The magnitude of active force was significantly decreased after 125 minute run. The magnitude of maximum peak and maximum frequency of the mediolateral GRF at heel strike and toe-off have not been changed with increasing running time. The time up to the maximum peak of the anteroposterior at heel-strike moment tend to decrease (p<.05), but the maximum peak and frequency of that at heel and toe-off moment didn't depend significantly on running time.

The common features of walking in patients with stroke include decreased gait velocity and increased asymmetrical gait pattern. The purpose of this study was to identify important factors related to impairments in gait velocity and asymmetry in chronic stroke patients. The subjects were 30 independently ambulating subjects with chronic stroke. The subjects' impairments were examined, including the isokinetic peak torque of knee extensors, knee flexors, ankle plantarflexors, and ankle dorsiflexors. Passive and active ranges of motion (ROM) of the ankle joint, ankle plantarflexor spasticity, joint position senses of the knee and ankle joint, and balance were examined together. In addition, gait velocity and temporal and spatial asymmetry were evaluated with subjects walking at their comfortable speed. Pearson correlations and multiple regressions were used to measure the relationships between impairments and gait speed and impairments and asymmetry. Regression analyses revealed that ankle passive ROM and peak torque of knee flexors were important factors for gait velocity ($R^2=.41$), while ankle passive ROM was the most important determinant for temporal asymmetry ($R^2=.35$). In addition, knee extensor peak torque was the most significant factor for gait spatial asymmetry ($R^2=.17$). Limitation in ankle passive ROM and weakness of the knee flexor were major contributors to slow gait velocity. Moreover, limited passive ROM in the ankle influenced the level of temporal gait asymmetry in chronic stroke patients. Our findings suggest that stroke rehabilitation programs aiming to improve gait velocity and temporal asymmetry should include stretching exercise for the ankle joint.
