The purpose of this study is to compare Ultra Sound(U-S), Silver Spike Point(SSP) and Electro-Acupuncture(E-A) with each other and to objectively analyze their concrete validities and their effects on the deactivation of trigger points in patients with myofascial pain syndrome, and to provide basic necessary principles for clinical therapists. Sixty patients were randomly distributed into three groups of twenty persons each and the U-S, the SSP and the E-A were applied to each group respectively. Tree pain evaluation methods of VAS(Visual Analogue Scale), Electrical Stimulation Scale and Pressure Algometer were adopted to measure the effectiveness of each therapy. The results were as follows: The U-S and E-A groups demonstrated statistically significant decrease on the VAS. The pain thresholds by Electrical Stimulation Scale method was increased for all the groups of U-S, SSP and E-A with no statistical significance. however, Pressure Algometer method was found to increase the pain thresholds for both SSP and E-A groups with statistically significance. Statistically significant improvement was found for all the groups together after the administration of the U-S, the SSP and the E-A. From the above results, three methods of U-S, SSP and E-A are found to be effective tools for the deactivation of trigger points in patients with upper trapezius muscle of Myofascial Pain Syndrome. The E-A method was found to be the most effective among three methods.

When any damage or disease occurs, muscular strength and muscular endurance are lowered, and thus, if one is able to be restored from the damage or the disease, appropriate stimulus is required, since the muscles have to restore their proper functions. For such stimulus, the way of exercising and the way using electric stimulus are used in physical therapy. In order to examine the change in muscular strength, muscular endurance and girth of limbs for Biceps brachii, according to the lands of stimulus, in this article a total of 42 healthy male and female adults in their twenties were randomly sampled, and a series of tests were conducted for 6 weeks, for 15 minutes per once, 3 times per week, respectively, dividing them into the group for RUS(Russian Current Stimulation), PRE(Progressive Resistive Exercise) and P+R(RUS + PRE). The findings showed that the change in muscular strength was most significant as for the group for P+R, since it increased from $62.12{\pm}25.30$ before experiment to $95.78{\pm}34.07$ after 6 weeks: the change in muscular endurance was most significant as for the group for P+R, since it increased from $17.57{\pm}6.63$ to $42.86{\pm}10.24$; and the change in the girth of limbs was slightly significant only in the group for P+R, and the remaining two groups showed no significance.

Purpose: The purpose of this study was to examine the effects of static stretching and Evjenth-Hamberg stretching on isokinetic muscle strength of knee flexors and extensors. Methods: The subjects were composed of eighty healthy males without weight-training experience. ROM of knee joint measured active maximal extension and isokinetic Peak Torque measured $60^{\circ}/sec,\;120^{\circ}/sec$ using an the En-Knee. Three tests(Baseline, 4 weeks, 8 weeks, respectively) was operated to examine change of each variable. Data were analyzed with a $2{\times}3$ analysis of variance ($group{\times}test$) for repeated measures on last factor by SPSS package 10.0. The data analysis revealed muscle strength were dependent on stretching method. Results: The results were as follows. First, Evjenth-Hamberg stretching(E-HS) was more effective than static stretching(SS) on ROM. Second, Peak Torque of knee flexors and extensors was improved in both methods by each time. but E-HS was more improved than SS. Conclusion: In conclusion, This study indicates that E-HS is more efficient than SS on muscle strength improvement.

This study purposes at applying knee joint taping to preventing muscle fatigue. Twenty six subjects between the ages of 20s and 30s were randomly sampled among healthy males, with an average age of 26yr(range, 22 to 31yr). None of the subjects had a recent or remote history of significant lower extremity injury, No subjects had a history of central nervous system equilibrium problems. To develop muscle fatigue, Isokinetic exercise, which is a repetition of flexion and extension knee joint to $180^{\circ}$/sec, was performed 50 times per person. During the exercise, change of proprioception were measured by applying taping on both knee joints. Analysis has carried out by means of one-way ANOVA with repeated measures and independent t-test at the significance level of $\alpha$=0.05 to detect statistic significance. The results of this study were as follows: First, it was found that the generation of lower extremity muscle fatigue significant affects on proprioception (p < 0.05). Second, the application of taping to knee joint after the generation of lower extremity muscle fatigue significant affect proprioception (p < 0.05). Third, while continual exercise after the generation of muscle fatigue, taping group was significant differences in proprioceptive loss than non-taping group(p < 0.05).

Purpose. This study was tried to compare the effect of the change in postural deviation caused by the pain side Subjects and Methods. Inpatients and outpatients (n=71) were selected from I hospital who have a musculoskeletal low back pain and shoulder pain without any history of the central nervous system (CNS) lesions, orthopaedic problems of the both lower extremities, or the vestibular and the visual default. For the control group, normal and healthy subjects (n=30) were selected without any history of weight bearing disorders. the weight bearing was rated by the computerized force plate. Results. 1) Postural deviation was not significant difference between patients and control group(p<0.01). But postural deviation in patients was more pronounced than control group. 2) There was significant difference of postural deviation between in patients according to the pain side(p<0.01). When the pain side was on the left side, postural deviation tended to the right. When the pain side was on the right side and vertebral body, postural deviation tended to the left. 3) There was no significant difference of postural deviation between regional pain in shoulder and regional pain in low back(p<0.01). Discussions and Conclusion. As a result, the pain, for sure, affected the good posture and its keeping process directly or/and indirectly. Therefore, as the postural deviation increases, the additional energy consumption increased by the works of the muscles to keep the good posture. Preponderated postural deviation, furthermore, could load too much to the musculoskeletal system, leading to increase the pain. The postural deviation, a result of the pain, can cause a secondary deformity of the distal area as a compensatory reaction, and this compensation actually become a cause of the musculoskeletal symptom back in a cycle. Therefore, the appropriate treatment of the musculoskeletal problem and the education of the posture correction should be given to decrease the pain, preventing the secondary deformities, and increasing muscle energy efficiency of the posture remaining muscles.

Purpose: This study was conducted to determine how stimulation using Russian current changes isokinetic exercise performance of quadriceps muscle and its antagonist muscles. Methods: Subjects were 20 20-year-old healthy adults who were instructed in the flexion to extension of knees in angular velocity 60°/sec and 180°/sec using a Biodex (Biodex system 3). We measured the difference in muscle performance between the Russian current stimulated at the same time during the flexion to extension of knees and not stimulated. Results: The results showed that when Russian current stimulation was applied at the angular velocity 60°/sec, the flexed and extended muscles and the angular velocity 180°/sec increased significantly, but the peak torque of flexing muscles at the angular velocity 180°/sec did not increase. Conclusion: These findings suggest that Russian current stimulation with isokinetic exercise of the knee joint could affect the quadriceps muscle and its antagonist muscle performance of muscle strength and endurance.
