Purpose: The purpose of this study was to investigate PNF exercises for balance ability in elderly. Methods: This is a literature study with books and articles. Results: The balance ability in elderly is reduced by decreasing proprioception, visual and vestibular sensation. PNF exercise is highly efficient for functional activities to control posture and movement. It is also highly efficient for balance ability in elderly. This is considered effective exercise program for maintain and to promote balance ability in elderly. Conclusion: PNF exercise is highly efficient for functional activities to control posture and movement. In addition, it is also efficient for balancing posture and movement in cooperation with visual information and vestibular system. This exercise is considered to be effective exercise program to maintain posture and improve balance ability.

Purpose: The purpose of this study is to analyze the effect of the arm extension pattern of proprioceptive exercise program on the muscle activity of the opposite lower extremity. Methods: In this study, electromyogram MP150(Biopac system, USA) was applied to 20 healthy male subjects. Arm extensionadduction- internal rotation pattern was applied within initial, mid and end range in sling position and supine position for measurement. And the effect on the activity of rectus femoris and tibialis anterior muscle of the opposite lower extremity was compared and analyzed. Results: The results of this study were summarized as follows: First, there was a statistically significant difference of the activity of the tibialis anterior muscle within the Initial range in sling position and supine position(P<0.05). Second, there was a statistically significant difference of the activity of the tibialis anterior muscle within the end range in sling position and supine position(P<0.05). Conclusion: Rectus femoris and tibialis anterior muscles shows the higher activity in the supine position than in the sling position. Therefore, the supine position is more appropriate than the sling position to make irradiation on lower extremity muscle with the extension pattern.

Purpose: To determine the normative data for the correlation of spinal, pelvic parameters with foot pressure in the young subjects. Methods: The subjects of this study were 39 patients in healthy adults. The Formetric-III was used to measure of spinal alignment. The pedoscan was used to measure of foot pressure. The correlation of trunk imbalance, trunk inclination, lateral deviation with foot pressure. The foot pressure measurement was consisted of maximal/mean pressure, weight contribution. Result: There was a negative correlation of trunk inclination with Max_R. There was a negative correlation of trunk inclination with Max_R. There was a positive correlation of trunk imbalance with Max_L. There was a positive correlation of lumbar lordosis with Mean_R_front, Lt. posterior weight distribution. There was a negative correlation of lumbar lordosis with Lt., Rt. in distribution There was a negative correlation of pelvic tilt with Mean_R_front, Lt. posterior weight distribution. There was a positive correlation of pelvic tilting with Rt. weight distribution, Lt. posterior weight distribution. There was a negative correlation of pelvic torsion with Lt. weight distribution, Rt. posterior weight distribution. There was a negative correlation of pelvic rotation with Lt. weight distribution, Lt. posterior weight distribution. Conclusion: The data obtained from the study may be used for future studies related to correlation of the spinal, pelvic deviation with foot pressure.

Purpose: To investigate the effect of action observation training on the muscle onset time and symmetrical use of rectus femoris(RF) and gastrocnemius medialis(GCM) during sit-to-stand (STS). Methods: Sixteen patients with stroke entered a single-blind trial and were randomly assigned to the experimental(Action) or control(Landscape) groups. Those in the Action observation group watched video clips showing specific movement and strategies to STS, wheas those in the control group watched video clips of static pictures showing differnet landscapes. All patients was measured the EMG data in the STS on the affected side and unaffected side. The EMG data were collected from RF and GCM while performing the STS task. The EMG onset time and onset time ratio for the RF and GCM were calculated by dividing the EMG onset time of RF and GCM action on the affected side by these on the unaffected side. Results: Onset time of affected side RF, GCM was significantly faster action observation training group than control group(p<.05). But interventions before and after the symmetry did not show a significant increase. Conclusion: There findings suggest that action observation training has a positive effect on the muscle onset time shortened during STS tasks.

Purpose: This study was to identify the effects of the application of ankle pumping exercise versus elastic compression stockings for the women lower leg edema and pain due to continuous standing work. Methods: The participants were 20 women with leg edema and pain, divided into two group, 10 ankle exercise group and elastic compression stockings group. Low leg circumference were measured before and after work. Ankle pumping exercise group, elastic compression stockings were divided into groups, individual working one week during the arbitration to arbitration and work around the legs before and after retesting were compared before and after arbitration. Arbitration to stop and keep the information a week after the re-measurement of intervention before and after the arbitration and the degree of intervention were maintained. Statistical methods before and after working around the average value of each the legs was repeated measures ANOVA. Results: The participants had edema and leg problems because of their work. The ankle pumping exercise gorup and elastic compression stockings group showed statistically decrease in leg circumference value. there was no statistically value about the lasting effect of intervention after 1 week. Conclusion: The results of this study revealed that the application of elastic compression stockings and ankle pumping exercises during the hours of work is effective the relief of edema of lower extremity

Purpose: In this research, the properties of the shoulder joint were measured through eccentric resistive exercise with the patients who have rotator cuff tear of shoulder joints as the targets. Methods: 23 patients who have pain due to the rupture of rotator cuff on shoulder joints were selected and divided into Exercise group (12) and Control group (11). Two groups executed exercise for 30 minutes 3 days a week. Exercise group had executed eccentric resistive exercise, and the Control group executed Complex exercise. Results: In external rotation 180°/s, 240°/s, the Exercise group showed to be an average of 8% higher than the Control group. For Internal rotation 90°/s, 180°/s, 240°/s the Exercise group showed to be an average of 30% higher that the Control group. Conclusion: To lessen the rupture of rotator cuff on shoulder joints, muscles strengthening is very important across various methods of eccentric exercise programs which are external/internal rotators of the shoulder joint needed for throwing. This is effective in preventing injury and improving rotation.

Purpose: This study was to examine lateral abdominal muscle activation during maximum expiration exercise between healthy and chronic low back pain(CLBP) patients. Methods: The subjects were 16 CLBP patients and 16 healthy people between the ages of 22 and 53. The thickness of the abdominal muscles was measured using ultrasonography(LOGIQ Book XP, GE, USA). We instructed the subjects how to perform the exercises and measured changes in thickness of the transversus abdominis(TrA) and internal oblique(IO) muscles during the maximum expiration. The main outcome variables were the ratios of the TrA and IO thickness during the exercise versus in the relaxed position (TrA and IO activation ratios). Results: There were significant differences between CLBP patients and healthy subjects for TrA in the relaxed position. However there was no difference in the ratio of change in the muscle activity(TrA, IO). Conclusion: These findings, CLBP patients exhibited atrophy of the TrA muscle, but voluntary TrA muscle activation was similar to that of the normal subjects. Therefore, this exercise could be used during core strengthening in CLBP patients.

Purpose: Deficits in upper-extremity function in individuals with tetraplegia are primarily due to the loss of motor pathways. The purpose of this case report is to describe the effect of closed kinetic chain exercise using PNF on hand function and ADL of patient with incomplete spinal cord injure. Methods: Patient was a 53-year-old man with C4 tetraplegia and hand and upper extremity impairment who participated in this training intervention for 10 weeks. Results: Patient demonstrated improvements in upper extremity strength, hand function and performance of ADL. Outcome measures(ASIA motor scale, Hand power, Jebsen–Taylor Hand Function test, SCIM) were measured before and after the training program. Conclusion: The results of this case suggests that an closed kinetic chain exercise program in incomplete spinal cord injury patient may induce Hand function and ADL.
