Background: The purpose of this study was to investigate the effect of various relaxation techniques on various dysfunction problems caused by shortening of the sagittal muscles. Method: The subjects were 44(18 males, 26 females). The subjects were composed of 3 groups. The experimental group consisted of 14 patients with proprioceptive neuromuscular facilitation stretching (PNF) technique, control group A 15 patients with self myofacial release (SMR) ball exercise, and control group B with 15 patients with Sling exercise. After 3 weeks of relaxation on the hamstring muscle, the length of the hamstring muscle before and after the intervention was compared. Results: The results of relaxation exercise of the snake muscles applied to passive PNF group, SMR ball group, and Sling relaxation group are as follows. 1. In the passive PNF group, the muscle length of the hamstring muscle was significantly increased after the intervention. 2. The muscle length of the hamstring muscle was significantly increased after the intervention in the SMR ball group. 3. Sling relaxation group significantly increased the muscle length of the hamstring muscle after sling exercise intervention. 4. Passive PNF group showed the greatest change in muscle length before and after intervention than SMR ball group and Sling relaxation group. Conclusion: Passive PNF relaxation therapy, SMR ball relaxation therapy, and Sling relaxation therapy applied to the hamstring muscle were effective in increasing muscle length of the hamstring muscle. PNF relaxation therapy showed the most significant effect after 3 weeks intervention.
Objective: This study was executed to compare and analyze shoulder muscle activation while using an inelastic bar and elastic bar during overhead press exercise. The stability and coordination of shoulder joints will be investigated by measuring and analyzing the EMG of the upper and lower arm muscles. Method: A total of 20 university male students were recruited by dividing into 2 groups; 10 elastic bar participants (age: 20.17 ± 0.41 yrs, height: 174.31 ± 3.34 cm, weight: 74.68 ± 5.65 kg) and 10 inelastic bar participants (age: 20.09 ± 0.23 yrs, height: 173.53 ± 4.11 cm, weight: 75.32 ± 3.31 kg) participated in this study. Results: The EMG analysis results of the four muscles measured in this study showed that there was no difference between the left and right muscles between the groups in Upper Trapezius muscle. In Deltoid, Infraspinatus, and Rectus Abdominis muscles, the elastic bar group was significantly higher than the inelastic bar group between groups, and there was no difference between left and right. Conclusion: Among the four muscles measured in this study, there was no difference between left and right in Deltoid, Infraspinatus, and Rectus Abdominis, but the elastic bar showed significantly higher muscle activity than the inelastic bar. Therefore, it was found that the elastic bar increases muscle activation during exercise than the inelastic bar, and in particular, it further increases muscle activation of the arms and torso, and exercise using the elastic bar can increase neuromuscular stabilization.
Purpose: Balance and walking ability are important elements of functional independence for people with stroke and are major goals in rehabilitation. These abilities require trunk performance, but most chronic stroke patients reach a plateau in their rehabilitation. Therefore, the purpose of this study was to investigate the effects of a self-training trunk program to improve balance and walking ability in people with stroke, and to suggest such a self-training program for integrated rehabilitation of people with stroke. Methods: The study recruited 7 people with stroke. The subjects performed trunk training for 30 min per day, 6 days per week, for 3 weeks. Participants were measured on the Trunk Impairment Scale (TIS), the Berg Balance Scale (BBS), the Korean Activities-specific Balance Confidence (K-ABC) scale, the Falls Efficacy Scale (FES), the Functional Gait Assessment (FGA), the 6 Minute Walk Test (6MWT) and a gait analysis to measure the training effects. Statistical analysis used the Wilcoxon signed-rank test as a non-parametric statistical test. Results: TIS was not significantly different after the self-training trunk program, but BBS (p>0.05), K-ABC, and FES were significantly improved after the training program (p<0.05). Furthermore, the 6MWT, stride/height %, and one-leg stance were significantly improved after the training program (p<0.05), but cadence, stance, and swing duration were not significantly different after the training (p>0.05). Conclusion: These results suggest that a self-training trunk program should be integrated into stroke rehabilitation to improve balance and walking ability, and further research is needed to develop the program to be more effective for chronic stroke patients.

Purpose: This study aimed to investigate the effect of visual feedback training-for gradual weight shift in sit-to-stand training-on the balance and walking abilities of chronic hemiplegia patients. Methods: Twenty patients with chronic hemiplegia volunteered to participate in this study. The experimental group received visual feedback for gradual weight shift in the sit-to-stand training, while the contrast group followed the standard process for the sit-to-stand training. The evaluation of the balance and walking ability was conducted with the functional reach test (FRT), Berg balance scale (BBS), five time sit-to-stand (FTSTS) test, timed up and go (TUG) test, 10 m walk test (10MWT), balancia, activities-specific balance confidence (ABC) scale, and falls efficacy scale (FES). Results: In the results before and after intervention, there was a significant difference in TUG, 10MWT, ABC, and FES in the visual feedback training group (p < 0.05). In the control group, there was a significant difference in the 10MWT and ABC (p < 0.05). Also, in the evaluation of the postural fluctuations, the control group data showed a significant increase in Covar. The visual feedback group showed a significant difference in the W average. Conclusion: The visual feedback training group showed some improvement in terms balance and walking ability and on the ABC scale and FES. Therefore, if the diagonal progressive weight bearing exercise is combined with the various patterns and basic principles of PNF, it may be a more efficient intervention method.
Purpose : The purpose of this study is to examine the muscle activity of shoulder stabilization according to change of supporting base interval between push-up bend and push-up plus position and is to prevent or treat a shoulder injury by the most effective exercise for rehabilitation. Methods : This study analyzed the muscle activity according to change of supporting base interval between push-up bend and push-up plus movement. The participants without neuromuscular disease were 25 students - 12 males and 13 females - all twenty or over and the surface electrode of EMG attached on pectoralis major, triceps long head, middle trapezius, lower trapezius, serratus anterior and latissimus dorsi. The process has practiced 3 sessions of supporting base interval - narrowing interval, two shoulder interval, broad interval - by push-up bend and push-up plus movement. Result : 1. The muscle activity of pectoralis major was significantly increased according to narrow interval of supporting base on push-up plus movement and was significant difference(p<.05). 2. The muscle activity of biceps was significantly increased according to narrow interval of supporting base on push-up bend movement(p<.05). 3. The muscle activity of middle or lower trapezius was a difference according to change of supporting base on push-up bend and push-up plus movement but was not significant difference. 4. The muscle activity of serratus anterior was significantly increased according to broad interval of supporting base on push-up bend movement(p<.05). 5. The muscle activity of latissimus dorsi was significantly increased according to broad interval of supporting base on push-up bend movement(p<.05). Conclusion : These results lead us to the conclusion that push-up bend exercise have the effect of muscle strength of biceps on narrowing interval, of serratus anterior or latissimus dorsi on broad interval and push-up plus exercise have the effect of muscle strength of pectoralis major on narrowing interval of support base.
Purpose: This study investigated the effects of virtual reality-based task training (VRBTT) using a smart glove on upper extremity function and activity of daily living in stroke patients. Methods: Twenty-nine patients with chronic stroke disease were randomly allocated to two groups: the VRBTT group (n=14) and the control group (n=15). All patients received 30 minutes of standard occupational therapy, 5 times a week, for 8 weeks. The VRBTT group performed an additional 30 minutes of virtual reality-based rehabilitation training, 5 times a week, for 8 weeks. Results: Both groups showed significant improvements in upper extremity function, yielding an increase in FMA and K-WMFT (p<0.05). There was a more significant increase in the VRBTT group before and after interventions (p<0.05). There was no significant difference in MAS for the control group (p>0.05); however, there was a significant increase for the VRBTT group (p<0.05). In the activities of daily living, there was a significant difference in the values for K-MBI (p<0.05). In addition, both groups showed a significant increase for K-MBI and K-RNLI (p<0.05). Conclusion: This study showed that VRBTT using smart gloves can have a more positive effect on upper extremity function and activities of daily living in stroke patients than conventional intervention methods. A variety of virtual reality-based contents and glove-shaped wearable devices will help stroke patients in rehabilitation clinics recover and return to society.
Purpose: The purpose of this study was to determine the asymmetrical difference between the use of leg muscles on the surgical and non-surgical sides during initial lower extremity ergometer exercise after unilateral knee arthroplasty. Methods: Twelve elderly patients diagnosed with degenerative arthritis of the knee and who underwent unilateral arthroplasty were included in this study. The leg length of each subject was taken into account when setting the application distance of the lower extremity ergometer. The same pedal resistance, strength, and speed were used for all the subjects. The total angle of use of the ergometer (360°) was analyzed by dividing it into an extension section and a flexion section. Using a surface electromyography system, the activities of the muscles of the surgical and non-surgical sides were converted into maximal voluntary isometric contraction (MVIC) and analyzed using the paired t-test. Results: When the activities of the muscles on the surgical and non-surgical sides were compared, it was found that the rectus femoris and biceps femoris had significant differences in the flexion and extension sections (p < .05), and that the tibialis anterior significantly differed in the flexion section (p < .05). There was no significant difference in the extension section of the tibialis anterior muscle, or in the flexion and extension sections of the gastrocnemius (p >.05). Conclusion: The results of this study confirm that the rectus femoris, tibialis anterior, biceps femoris, and gastrocnemius on the surgical side act in an opposite manner to those on the non-surgical side during pedaling in the same section.
The purpose of this study was to determine whether PNF respiratory exercise increases the vital capacity and maximal voluntary volume of 20s normal adults by 45° leaning sitting position. Twenty normal adults in their 20s were randomly assigned to an experimental group and control group. Over the course of four weeks, the experimental group participated in PNF respiration exercises by 45° leaning position for 30 minutes three per week. And the control group participated in diaphragm respiration exercises by 45° leaning position for 30 minutes three times per week. Subjects were assessed post-test by measurement of vital capacity, maximal voluntary volume. Our findings show that the experimental group had significant improvements in vital capacity, maximal voluntary volume(p<.05). In this study, the experimental group showed more improvement in pulmonary function, which indicates that the PNF respiratory exercise by 45° leaning sitting position is effective at increasing the pulmonary function of normal adults.

Purpose : When the pliability of the Lumbar is degraded, the kinesiology function undergoes an influence and it receives an overload. Finally, it is connected with a Lumbar muscular injury. When it does the regular exercise treatment the lumbago patient the balance and function of changeover are improved. The purpose of this study is to review of effect of the PNF application for lumbago patient Methods : By using internet, we research the PubMed, Science Direct, KISS, DBpia and the article on the effect of PNF. We selected the article between 1970 and 2007. Key words were low back pain, lumbago, PNF. Results : PNF is a therapeutic exercise for central nervous system(CNS) patient and the peripheral nervous system(PNS) patient and it is widely applied from sports medicine in the last. According to research of the Jung Young Jo(2007) and Han Kou Soo(2002), PNF technique improves the pain and a condition of the lumbago patient. And the affection balanced change and dynamic balance change and spontaneous movable scope are improved. And it improved to daily life activity. According to research of Moore and Hutton(1980), Lee Kyoung Hye(1999), PNF stretching where it is one of muscular relaxation is good in lumbar muscle fascia ache solutions, and PNF stretching that muscle is relaxed and increases ROM by Reflective system of the vertebra. These researches is relation all each other. it have appeared many report of research about Pliability, muscular power, balance, mobility improve ADL movement of attendance ability and functional action improved excise therapy put effect about lumbago patient recently, it have appeared research about therapy of lumbago patient through PNF. But PNF technique is not application about lumbago patient in clinic, therefore also it is not enough for case study about this therapy. Conclusion : PNF improve combination operation of muscle, inconvenience decrease from daily life activity, ROM(range of movement) of lumbar is increase and Lumbago reduce. So we suggest that PNF will be applies on the lumbago patient and must do a many research.
Purpose: The purpose of the present study was to examine the effects of the simultaneous application of the combination of isotonics (CI) in proprioceptive neuromuscular facilitation (PNF) and sport taping on the pain and grip strength of patients diagnosed with lateral epicondylitis among H badminton club members and to provide intervention methods for lateral epicondylitis. Methods: The subjects included 10 patients diagnosed with lateral epicondylitis. The CI technique in PNF as well as sport taping were applied to the subjects five times per week for two weeks. The visible analogue scale (VAS) was used to measure decreasing changes in pain, and a grip dynamometer was used to measure grip strength (GS). Paired sample t-tests were conducted to compare values measured before and after the experiment in order to determine differences. Results: The intensities of pain of the experimental groups changed significantly between the times before and after the experiment (p<0.05), and grip strength also changed significantly from the time before after the experiment (p<0.05). Conclusion: When the CI technique of PNF as well as sport taping were applied to patients with lateral epicondylitis, the patients showed significant improvements in pain and grip strength. Since the intervention had quite positive effects on the subjects that complained of lateral epicondylitis by reducing their pain and increasing their grip strength, studies of efficient exercise interventions will be continuously conducted to propose the development of intervention programs.
