In this paper, we propose a taping therapy as effective intervention for patients with the back pain. The purpose of this study is to investigate the effects of taping intervention on the VAS evaluated score and he muscular activation degree among 119 paramedics with musculoskeletal injury. In order to achieve the purpose of the study, data was collected from 15 paramediecs in the paramedics department of 3 fire stations under J city's fire defense headquarters. The following results can be obtained by measuring the subjective, the back muscle strength and the buckling-anteflexion before and after the taping for 15 119 paramedics. Through the verification experiment of taping effect to paramedics during the stretcher lifting in this study the VAS evaluated score for the backache are $1.67{\pm}0.62$ before and $0.80{\pm}0.68$ after the application of taping which show statistically significant decrease(p<0.05). In the experimentof joint operation range the measured buckling anteflexion length are $14.62cm{\pm}4.89$ before and $16.41cm{\pm}4.11cm$ after the application of taping which show statistically meaningful difference(p<0.05). In the comparison of muscle activity about paramedics erector spinae(ES) shows the meaningful decrease and external obliques(EO) displays the significant increase. Erector spinae(ES) and internal obliques(IO) show the increasing trend in the muscle activity although they are not significant. the muscle activity for the erector spinae is lowered so that the contribution to the force required for the extensor during the stretcher lifting is resultingly reduced to have the effects of enhancing the activity of abdominal muscles.

Purpose : The purpose of this research was to develop a proposal by investigating the work habits associated with exercise programs for the prevention of chronic back pain. Methods : The symptoms, areas and causes of musculoskeletal patients were analyzed during a three-month period in order to develop and apply prevention programs that stimulate lumbar deep layer muscle movement. Results : The results of this study show that the lumbar and shoulders are primary areas of pain. According to the literature, lumbar and shoulder pain is caused due to long periods in the standing position and unhealthy posture during work. A preliminary program was conducted for one month to study lower back pain prevention. Preliminary results of the program showed a lumbar stabilizing effect caused by the strengthening of abdominal muscles. In addition, the alignment of the spine often leads to effective action. Therefore, action-oriented programs should be implemented in order to induce contractions of the transverse abdominis muscle. Conclusion : The completed program should consider habit and practices of workers within their working environment. The promotion of health through exercise for both employers and workers is expected to bring physical and psychological benefits that will positively affect economic results.

PURPOSE: Prone hip extension (PHE) has been used for assessment of lumbo-pelvic movement and strengthening exercise for weakness of the hip joint muscles in patients with chronic low back pain (CLBP). On the other hand, few studies have examined which are the best PHE exercises to activate the gluteus maximus (GM) selectively in physical therapy practice. To aim of this study compared the muscle activity of the GM, rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA) during these four different prone hip extensions, PHE, PHE with quadriceps activation (PHEQA), PHE with ankle dorsiflexion (PHEAD), and PHE with ankle plantarflexion (PHEAP), in subjects with CLBP. METHODS: Nineteen subjects with low back pain participated in this study. Subject performed four PHE exercises and surface electromyography (EMG) was used to evaluate the muscle activity. Data were analyzed by one-way repeated-measures analysis of variance (${\alpha}=.05/3=.017$) and a Bonferroni adjustment was performed if a significant difference was found. RESULTS: The muscle activities recorded by EMG showed significant among the four exercises. The muscle activity of the GM increased significantly during PHEQA than during PHEAP (P=.012). CONCLUSION: PHEQA is the most effective exercise for eliciting greater GM muscle activation among the four PHE exercises in subjects with CLBP.

Objectives: The purpose of this study was to investigate the effect of intensive rehabilitation programs on pain, range of motion (ROM), lumbar muscle strength, core muscle endurance, disability, and depression in patients with traumatic low back injuries and to compare the efficacy of this therapy with that of conventional rehabilitation therapy. Methods: The study was performed with a retrospective medical chart review of patients with traumatic low back injury referred to the rehabilitation center at the Daegu Hospital of the Korean Workers Compensation and Welfare Service. Forty-four patients were allocated to either the conventional rehabilitation group (CRG; n = 22) or the intensive rehabilitation group (IRG; n = 22). The CRG group patients, who received 30-min therapist-supervised physical therapy and modality therapy five times per week for four weeks, were compared with the IRG group patients, who received 60-min therapist-supervised physical therapy, 30-min therapist-patient 1:1 matching rehabilitation therapy, and modality therapy five times per week for four weeks. Outcome measures were a numerical rating scale, ROM, lumbar muscle strength, lumbar core muscle endurance, thickness of lumbar deep focal core muscle (transverse abdominis and lumbar multifidus), Oswestry disability index (ODI), and depression (Korean version patient health questionnaire-9). Results: There were statistically significant improvements after treatment in all outcome measures in both groups (p < 0.05). In the intergroup comparison, NRS scores on the activity and thickness of lumbar deep focal core muscles increased significantly more in the IRG than in the CRG (p < 0.05). There were no statistically significant intergroup differences in NRS scores on resting, ROM except left lateral bending, lumbar muscle strength, core muscle endurance, ODI, and depression. Conclusions: We could confirm the superior effectiveness of an intensive rehabilitation program compared to conventional rehabilitation therapy in patients with traumatic low back injuries.

J. R. PARK. The Analysis of Electrimyography and Kinematic of Kumdo Player's Head Hitting. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 63-74, 2005. The purpose of this study were to describe and compare the selected electromyographical muscle activities of arm and kinematic data of kumdo player's head hitting. Using surface electrode electromyography, we evaluated muscle activity in 6 male players during head hitting motion. Surface electrodes were used to record the level of muscle activity in the carpi radialis, deltoid, triceps, biceps muscles during the player's head hitting. These signals were compared with %RVC(Reference voluntary contraction) which was normalized by IEMG(Integrated EMG). The kumdo head hitting motion was divided into two phases: back swing, down swing. we observed patterns of arm muscle activity throughout two phases of the kumdo head hiting The results can be summarized as follows: right elbow angle had decreased and left deltoid muscle's activation had higher than right deltoid muscle's activation, right carpi radialis muscle's activation had higher than left carpi radialis muscle's activation in back swing phase, knee angle had decreased and left triceps muscle's activation had higher than right triceps muscle's activation, right deltoid muscle's activation had higher than left deltoid muscle's activation, right carpi radialis muscle's activation had higher than left carpi radialis muscle's activation in down swing phase

Cerebrovascular Accident(stroke) is that a sudden, nonconvulsive loss of neurologic function due to an ischemic or hemorrhagic intracranial vascular event. If stroke happens at the portion of trigeminal motor nucleus or its control part of cerebral cortex, masticatory muscles will be atrophy or paralyzed. So it is possible that dental occlusion changes after stroke. A 74-aged woman recurred mild stroke 2 month ago, who had experienced severe stroke 2 years ago. After recurrence, suddenly her upper full denture was dropped when lower denture contacted upper one. According to the her occlusion exam, her lower jaw moved back slightly compared with the occlusion of old denture. And her face had asymmetry and lower jaw dislocated to paralyzed side. A 50-aged man was treated because many cervical caries, which would occur because of an aftereffect of stroke, long-herm hospitalization and limits of self oral-care. 6 years ago he had cerebral hemorrhage and he claimed that he cannot bite exactly. Just two pairs of teeth was contact on biting, his lower jaw was located back, too. This two case suggests that dental occlusion can change after stroke.

The conventional surgery method of thrombectomy of venous thrombi from the deep veins of the lower extremity was the use of Forgarty balloon catheter. The catheter is inconvenient due to the presence of the balloon and prohibiting venous valves within the venous trees. With the use of a stone-forceps(Fig. 1), thrombi within iliofemoral vein could be easily removed without the obstacle of the valves because the instrument keeps valves open. This instrument is also useful in monitoring the back-flow from the iliac vein. Thrombi within the veins below the level of inguinal incision are removed successfully only by effective manual compression of the calf and thigh muscles. 1 recommend operating on the iliac vein first rather than the lower venous tree.

Purpose: To recognize the change in the proprioception under conditions that activate the local muscles, this study found the difference in the proprioception on a fixed and swing chair. Methods: Healthy adults (7 males, 13 females) in their twenties were evaluated lumbar position sense on fixed and swing chair. And the difference of the position sense between the fixed and swing chair were analyzed. Results: The joint position senses were compared between the fixed and swing chair. As a result, there was a significant difference from all motions. Conclusion: This study found that the improvement of proprioception using swing chair means that the local muscle is activated. Therefore, to use a swing chair, which was designed in this study, is able to replace the general chair either at work or during studies. Thus, this method is easily accessible for busy modern people who are exposed to low back pain or spinal disorders due to a pattern of inactivity.

Purpose : Recommended posture according to the location of operating teeth have been standardized in dental clinic to prevent musculoskeletal disorder. However, clinicians do not comply with this rule in many cases. This study investigated the effects of operating posture on cranio-cervical range of motion (CROM) and muscles activity of neck and upper extremity. Methods : Sixteen healthy dental hygiene students were participated. During operating posture (3 recommended and 3 experimental postures which were set front, side, back, respectively), CROM in the fronal and sagittal plane were measured by Cervical Range of Motion Instrument and muscle activities of Sternocleidomastoid, upper trapezius, middle deltoid, extensor carpi radialis, brachioradialis, and abductor pollicis brevis were measured by Pocket EMG system. Result : CROM were significantly decreased in recommended posture in comparison with experimental posture (p<.05). In addition, muscle activity of middle deltoid was significantly decreased in recommended front posture. Moreover, brachioradialis and extensor carpi radialis showed the same result in recommended back posture (p<.05). Conclusion : Recommended posture is close to neutral posture and to reduce muscle fatigue and overuse, which may considered as a preventing musculoskeletal disorder and partially explain its efficacy in dental clinic.
