Purpose: The purpose of this study is to analyze the brain waves and develop various exercise programs to improve the physical and mental aspects of stroke patients when neurological physical therapy and sitting table tennis exercise are applied to stroke patients. Methods: In this study, an experiment was conducted on 15 patients diagnosed with stroke, and training was performed after changing the ping-pong table to a sitting position to apply ping-pong exercise to stroke patients. After training was conducted for 40 minutes twice a week for 4 weeks, brain waves were measured before and after. EEG was measured using Laxtha's DSI-24 equipment as a measurement tool, and data values were extracted through the Telescan program. Results: Most of the relative beta waves showed a significant difference before and after the intervention. As for the characteristics of beta waves, this result can be seen as being highly activated during exercise or other activities. Conclusion: Ping-pong exercise in a sitting position is a good intervention method for stroke patients, and it can help to use it as basic data in clinical practice by showing brain activity.

Purpose : This study investigates the effects on balanced ability and ankle joint muscle following balance pad and trampoline training periods in order to report a clinical directing about this matter. Methods : A total of nine members participated in a balance training program that put a balance pad and trampoline to use. Participants trained three times a week for thirty minutes in groups of six. Resting time was set for two minutes. EMG (median frequency and root mean square) was used to measure muscle activity at 3 weeks and 6 weeks, respectively. The tibialis anterior and gastrocnemius muscles were measured. Participants were measured with eyes open and closed. Results : The median frequency showed a significant difference according to the change in time in both muscles. Also, results showed a significant interaction between eyes open and closed in the gastrocnemius muscle. The root mean square only showed a significant difference according to the change in time in the gastrocnemius muscle. Conclusion : We suggest that the balance pad and trampoline training influence a decrease in the recruitment rate of slow twitch muscles through an improvement in balance ability; however, the training did not show a statistically significant difference with regards to eyes open and closed.

Background: The purpose of this study was to investigate how the resistive exercises with vibration stimuli could affect the strength of knee muscles and balance in patients with a history of reconstructive surgery. Methods: Thirty four subjects with anterior cruciate ligament reconstruction were randomly divided into 3 groups; Resistive exercises with vibration stimuli group (n=11), Resistive exercises (n=11) and control group (n=12). The paired t-test was used to show the variation before and after exercise in all three groups. One way ANOVA was used to separate the total variation between groups. Results: The results showed that there was significant improve in the strength of knee muscles in all three groups and resistive exercise with vibration stimuli he group showed a better result in all area than the other two groups. Comparisons of sway distances with open and closed eyes showed a statistically significant decrease before and after treatment in all three groups, there was no statistically significant difference between groups. There was a significant difference only in the sway distance with the eyes closed. Conclusions: Applying the resistive exercise with vibration stimuli as a therapeutic exercise program resulted in a positive effect to the functional activity not only in rapidly recovering the strength the weaken muscles and lost of balance ability, but also expecting an earlier return to daily life by advancing the date of the process for the functional activity.

Purpose: This study was to investigate the differences abdominal muscles activities of according to hip adductor contraction levels 20% (mild), 50% (moderate), and 70% (strong) of MVIC on during bilateral lower extremity raising exercise on supine. Methods: The subjects of the study were a total of 39 persons including 23 healthy males and 16 females, who performed bilateral lower extremity raising exercise in 20%, 50%, 70% MVIC hip contraction. Muscle activities were measured by using S-EMG in RA (rectus abdominis), IO (internal oblique), and EO (external oblique). Results: Muscle activity of the internal oblique abdominal muscle and external oblique abdominal muscle, their activities were also greatest with the adductor contraction size at 70% and there was statistically significant difference when compared with the adductor contraction size at 20% and 50% (p<0.05). As for the rectus abdominis muscle according to the size of contraction of the adductor was greatest at 70%, without statistically significant difference (p>0.05). Conclusion: bilateral lower extremity raising with strong hip joint adductor contraction was effective exercise to strengthen abdominal muscles. If subjects could not perform strong hip adductor contraction, moderate contraction is effective abdominal muscle contraction exercise. The contraction size of the adductor is small, weak contraction may trigger middle level contraction and therefore appropriate application of the exercise program of bilateral leg raising may result in great effect as a lumbar stabilization exercise.

PURPOSE: To investigate the effects of the underwater Ai-Chi exercise on the joint range of motion, balance and posture. METHODS: Thirty-six college students (30 men, 6 women) were divided into a 'low physical activity' groups (Group I). and an 'appropriate physical activity' groups (Group II). The Ai-Chi underwater exercise was conducted three times a week for two weeks for both groups. A goniometer was used to measure the range of motion of the hip joint, and Y-Balance and the posture screen mobile were used to measure the stability of the lower extremities. RESULTS: An evaluation of the range of motion of the hip joint before and after the Ai-Chi exercise showed significant results in the low physical activity group. However, the flexural range showed a significant increase after exercise, but not significant result. In the comparison of the mean increase between groups, only the right hip joint showed a significant difference in both groups. Also, in the comparison of the Y balance test and posture screen test before and after exercise, both groups showed significant. CONCLUSION: The Ai-Chi underwater exercise helped improve the range of motion of the hip joint and the ability to balance. Also It helped improve posture alignment. In addition, although the increase in all physical activity groups lower than the appropriate physical activity groups was greater in all figures, the increase in the number of samples, the extension of the experimental period, and various variables could be obtained.

Background: This study tried to identify the bridge exercise posture for efficient exercise application by comparing muscle activity of buttocks and thighs according to internal-external rotation and pronation & supination in bridge exercise. Method: Nine males in their 20s living in D city were randomly selected as subjects. Muscles such as vastus medialis oblique (VMO), vastus lateralis (VL), semitendinosus (ST), biceps femoris (BF), gluteus maximus (GMAX), gluteus medius (GMED), tensor fasciae latae(TFL), and adductor longus (ADL) were measured using eight channel surface electromyogram (MyoSystem 1400A, Noraxon, USA) to measure muscle activity. Statistics process was performed through paired t test. Results: In the changes in electromyogram signals according to internal-external rotations according to internal-external rotation of shinbones, in most cases muscle activity was higher in external rotation than in internal rotation, but there was no statistical significance (p>.05). In particular, it was lower in TFL and ADL. There was no statistical significance in the comparison between two groups (p>.05). In the changes in electromyogram signals according to internal-external rotations according to pronation & supination of thighs, GMED showed significantly higher value in supination than in pronation (p>.05), and in ADL pronation is significantly higher than supination (p<.05). Conclusion: In internal-external rotation of shinbone and pronation & supination of thighs in bridge exercise, changes in muscle length can make effects on muscle activity of buttocks and thighs. Therefore, muscle strength enforcement program on buttocks and thighs through bridge exercise can make effects on patients with lower limb functional damages in clinical situations.

PURPOSE: This examined the effects of a sling exercise based on music on the cognition, physical performance of patients with dementia. METHODS: Thirty subjects with dementia volunteered to participate in this study. All subjects were allocated randomly to either the experimental group or control group, with 15 subjects in each group. All subjects underwent the exercise program for an average of 60 minutes per day for 16 weeks. The experimental group performed sling exercise based on music, and the control group performed the general exercise program. Assessments were made using the Korean version of mini-mental state examination (MMSE-K), 10 m walk test (10MWT), Tinetti mobility test (TMT), and Katz's Index of Independence in activity daily living (KIIADL) to detect changes in the cognitive level and physical performance before and after the 16-week training period. A paired t-test was conducted to compare the within-group change before and after the intervention. An independent t-test was performed to compare the between-group difference. The statistical significance level was set to α=.05 for all variables. RESULTS: The experimental group showed significant within-group changes in the MMSE-K, 10MWT, TMT, and KIIADL (p<.05). The control group showed a significant change in only the KIIADL (p<.05). A significant difference was observed between the experimental group and the control group regarding the change in MMSE-K and KIIADL after the interventions (p<.05). CONCLUSION: A music-based sling exercise program effectively improves cognition, physical performance, and ADL in patients with dementia. Further studies with a wider range of subjects and scientific equipment will be needed to strengthen the results of this study.

Purpose: The purpose of this study was to investigate the effects of three exercise programs on forward head posture. Methods: Ninety-five individuals were recruited to assess the of the pectoralis minor muscle. Of these, 36 individuals with pectoralis minor muscles were selected and randomly divided into three groups: a functional massage group, a stretching group, and a stretching and muscle strengthening group. The exercise program consisted of sessions four times per week for two weeks. The length of pectoralis minor and the activity of the trapezius muscles were measured using electromyography. Forward head posture was assessed using the craniovertebral angle (CVA) and the cranial rotation angle (CRA) pre-, during and post-treatment. Result: Significant improvements were observed in pectoralis minor length, CRA, and CVA post-treatment in all groups (p<0.05, p<0.01, p<0.001). However, only the activity of the lower trapezius demonstrated a statistically significant difference post-treatment. There were no significant differences between the groups. Conclusion: The findings of this study suggest that all three exercise programs were effective in improving forward head posture and the length of pectoralis minor post-treatment.
