Objectives : Siguan points (LI4, LR3) have been most frequently applied for various diseases, especially different digestive disorders such as constipation, abdominal pain or various intestinal inflammatory diseases. The fact that gastrointestina movement is closely connected with physiologic functions or pathologic process of alimentary canal led us to ask the question if Siguan points affects on intestinal motility. Design: To investigate the effect of Siguan acupuncture on the intestinal movement in both physiologic and pathologic conditions, we divided the experimental animals into 12 groups. Six groups were pre-treated with loperamide (0.5 mg/kg, sc) or scoploamine (0.5 mg/kg, sc) to suppress the intestinal movement and another three groups were pretreated with carbachol (0.5 mg/kg, po) to activate it, whereas the rest three groups didn't receive any pretreatment to be kept in the physiological condition. After the administration with charcoal meal, mice were acupunctured bilaterally on sham point or Siguan points as the manner of tap-stimulation, with the exception of no acupuncture groups. Methods : Mice were scarified in twenty minutes after the administration of charcoal to measure the distance of charcoal passage from stomach-duodenal junction. The effect on intestinal movement was presented by calculating the relative distance where charcoal arrived to total length of small intestine. Results : In physiological state, charcoal meal passed around 53%, and there was no significant difference between Siguan points and sham points groups. On the other hand. Siguan points-sitimulation significantly ameliorated loperamide or scoplolamine-induced suppressed travel rate of 17.3 % and 18.6% in sham point into 26% and 26.3% respectively (p<0.05). In carbachol-induced accelerated condition, Siguan points-stimulation didn't affect intestinal motility comparing to sham point group passed about 97.6%. Conclusions : These results postulate that acupuncture at Siguan points have a therapeutic effect by restoring cholinergic activity on pathogenically suppressed intestinal peristalsis, but does not affect the gastrointestinal motility in the normal or accelerated condition.

It was clinically important to substitute the physiologic centric relation to the therapeutic position of the patients who needed the oral rehabilitation or occlusal treatment. There were several methods for recording the centric relation. One of the known methods was to use the gothic arch tracer. However the existing intraoral device was difficult to adjust the three dimensional angulation of the recording plate and recording stylus depending on the hinge movement arch of the individual. The purpose of this study was to develop new intraoral tracer which had adjustable stylus within hinge movement arch for the record of centric relation and to evaluate the clinical application of this device. The results were as follow; 1. A stylus of new developed intraoral tracer was so adjustable that the recording of mandibular positions could be reproducible within the hinge movement arc. 2. A record plate of new developed intraoral tracer was so adjustable to parallel with the occlusal plane that lateral recording of mandibular position was able to obtain stably. This study showed that new developed intraoral tracer allowed the determination of the treatment position which can be used in the full mouth rehabilitation and occlusal treatments.

This study attempted to reveal the physiologic etiology or related factors associated with speech processing by comparing the compensation ability in speech motor control in children with and without articulation disorders. Subjects were 35 children with articulation disorder and 35 children without articulation disorder whose age ranged from 5 to 6 years. They were asked to rapidly repeat /$p^ha$/, /$t^ha$/, /$k^ha$/, /$p^hat^hak^ha$/ diadochokinetic movement while mandible was free and mandible was stabilized with bite block. The results showed that children with articulation disorder revealed significantly greater difference in elapsed time for diadochokinetic movement between mandible free and stabilized state compared to the without articulation disorder group. But the correlation between the percentage of consonants correct and the compensation ability in speech motor control in the articulation disorder group was irrelevant. These results point out to the fact that children with articulation disorder have poor compensation ability in speech motor control compared to the children without articulation disorder. On the other hand, the poor ability does not have any relation with the severity of articulation disorder. These results suggest either general or individual characteristics of children with articulation disorder.

Purpose: The purpose of this study was to evaluate the effects of mobilization application for the lower extremity after fibula Pilon fracture operation patient. Methods: The subjects was 62 years old male who was injury of Lt. fibula shaft Fx., 3 cuneiform & cuboid Fx., 2.3.4 metatarsal bone Fx., We were compared to result of physical therapy between pre and post exercise for 2weeks. Results: The results of this study were summarized below; The mobilization application of the Lt. lower extremity was significantly differences of the ROM at pre and post therapy after 2 weeks, especially in knee flexion ($40^{\circ}$). The increased of accessary movement was evaluated to increased of the physiologic movement about the joints of the lower extremity. Conclusion: We consider that factors of therapy result were not only fracture types, operation and reduction methods for the fibula Pilon fracture but also the ability of physical therapist's manual techniques.

The severe wear of anterior teeth facilitates the loss of anterior guidance, which protects the posterior teeth from wear during excursive movement. The collapse of posterior teeth also results in the loss of normal occlusal plane and the reduction of the vertical dimension. This case report describes 77-year-old female, who had the loss of anterior guidance, the severe wear of dentition, and the reduction of the vertical dimension. Occlusal overlay splint was used after the decision of increasing vertical dimension by anatomical landmark, facial and physiologic measurement. Once the compatibility of the new vertical dimension had been confirmed, interim fixed restoration and the permanent reconstruction was initiated. This case reports that a satisfactory clinical result was achieved by restoring the vertical dimension with an improvement in esthetics and function.

Severe osteoarthrosis of the knee joint often requires total knee arthroplasty (TKA) to yield adequate knee function. The knee joint with TKA is expected ideally to restore the characteristics, however, this is not necessarily true in the clinical cases. In this study the motions of the intact joint and the joint after TKA were investigated numerically using computer simulation. For active knee extension from 90 degrees of flexion to full extension, the intact knee joint exhibited anterior tibial translation near the full extension while it showed only rotation for other flexion angles. Physiologic external rotation of the tibia near full extension was also noted in the analytical model. The analysis of the tibial insert of three different shapes (flat, semicurved, and curved types) demonstrated characteristic rotational and sliding motions as well as different contact forces.

Purpose : This paper reviews evidence supporting adaptive plasticity in skeletal muscle fibers induced by various exercise training and neuromuscular activity. Result : Skeletal muscle fiber demonstrates a remarkable adaptability and can adjust its physiologic and contractile makeup in response to alterations in functional demands. This adaptive plasticity results from the ability of muscle fibers to adjust their molecular, functional, and contractile properties in response to altered physiological demands, such as changes in exercise patterns and mechanical loading. The process of activity-dependent plasticity in skeletal muscle involves a multitude of signalling mechanisms initiating replication of specific genetic sequences, enabling subsequent translation of the genetic message and ultimately generating a series of myosin heavy chain isoform. Conclusions : Knowledge of the mechanisms and interaction of activity-dependent adaptive pathways in skeletal muscle is important for our understanding of the synthesis of muscle myosin protein, maintenance of metabolic and functional capacity with physical activity, and therapeutic intervention for functional improvement.

Severe osteoarthrosis of the knee joint often requires total knee arthroplasty(TKA) to yield adequate knee function. The knee joint with TKA is expected ideally to restore the characteristics, however, this is not necessarily 1.ue in the clinical cases. In this study the motion of the intact joint and the joint after. TKA were investigated numerically using computer simulation. For active knee extension from 90 degrees of flexion to full extension, the intact knee joint exhibited anterior tibial translation near the full extension and it showed only rotation at other flexion angles. Physiologic external rotation of the tibia near full extension known as screw home movement was also noted in the analytical model. The analysis of the tibial insert of three different shapes (flat, semicurved, and curved types) demonstrated characteristic rotational and sliding motion as well as different contact forces.

Purpose: The effect of orthognathic surgery on the temporomandibular dysfunction has been controversial. The purpose of this study is to prove statistically that early removal of fixation plate at postoperative 2 weeks with active exercise of mouth opening could relieve preoperative temporomandibular dysfunction and reposition of temporomandibular joint. Patients and Methods: All 28 subject patients underwent mandibular setback with BSSRO in Kyunghee medical center by one surgeon. The fixation plates used for rigid fixation were removed at postoperative 2 weeks and we had the patients excercise active mouth opening with intermaxillary rubber rings for the guiding proper postoperative occlusion. Temporomandibular symptoms were checked and radiographs were taken before surgery, within a month after surgery, six to twelve months after surgery respectively. Results: The temporomandibular dysfunction symptoms were relieved after the surgery and the condyle was displaced inferior-posteriorly immediate after surgery and repositioned toward its original position during follow-up periods. Conculusion: Orthognathic surgery may benefit temporomandibular joint dysfunction by obtaining a postoperative stable occlusion and more physiologic neuromuscular function. The early removal of fixation plates after BSSRO could reposition the temporomandibular joint to physiologic position and relieve the symptoms of temporomandibular dysfunction by permitting movement of proximal segment.
