The purpose of this study was to estimate primary diagnosis, prediction of prognosis and recognition fo treatment progress for treatment of TMD patients through measuring the various ranges of mandibular movement in normal and TMDs patients using Mandibular Kinesiograph K-6 Diagnostic system. In normal groups, 20 adults were selected, who have normal or class I molar relationship, and have no symptoms on TMJ and masticatory muscles, and have restorations less than 3 surfaces on each tooth, and have no other prosthetic restoration. In Patients group, we selected 31 outpatients who were confirmed to TMDs with clinical examination and radiographic findings. The obtained results were as follows : 1. In maximal opening, patient group was showed the limitation of vertical movement range (P<0.01) and lager lateral deviation than in normal group (P<0.05). And actual dimensional displacement of opening was calculated larger in normal group (P<0.05). 2. In protrusive movement, patients group was showed the limitation of anteroposterior movement range (P<0.001) and larger deviation than in normal group (P<0.01). And actual 3 dimensional displacement of protrusion was calculated larger in normal group (P<0.001). 3. In lateral maximum excursion, compared with normal group patient group was no significant differences to affected side, but was showed the limitation of lateral movement to unaffected side (P<0.001). 4. There was no significant difference in movement velocity of opening and closing in both groups. 5. Mandibular movement from physiologic rest position to centric occlusion was moved more anteroposteriorly in patient group. 6. Mandibular movement from centric relation to centric occlusion was no significant difference in both groups.

The method of treatment in skeletal Class III malocclusion must be chosen according to an etiology and timing of the treatment. Maxillry protraction has been used as an effective treatment method in growing children with maxillary deficiency. The efficacy of maxillary protraction has been viewed as a result of downward-backward displacement of mandible and compensatory dental displacement during the treatment rather than forward -downward growth of maxilla itself. In this study, 104 subjects treated with maxllary protraction, and 19 males and 21 females with known annual growth amount have been chosen longitudinally as treated group and normal group, respectively. And changes in position of maxilla, mandible and dentition have been comparatively analyzed on the lateral cephalometric radiographs by age. The results were as follows : 1. Treated group showed more forward movement of maxilla compare to the normal group and the mandible displaced backward compare to the normal group. 2. Downward movement of maxilla in treated group was similar to that of normal group with statistical signigicance in female 12 year old group and downward movement of mandible in treated group was similar to that of normal group. 3. In treated group, maxillary central incisor moved more forward than the normal group with statistical significance in male 8, 10 year-old groups and female 8, 9, 10 year-old groups. In treated group, downward movement of maxillary central incisor was similar to that of the normal group with statistical significance in male and female 7,8 year-old groups. Considering the above results and the duration of the treatment, the forward movement of maxilla due to maxillary protraction was effective compared to normal growth amount of the normal group.

Background: Research efforts to improve the pulmonary function of children with cerebral palsy (CP) need to focus on their decreased diaphragmatic ability compared to normal children. Real-time ultrasonography is appropriate for demonstrating diaphragmatic mechanisms. Objects: This study aimed to compare diaphragm movement, pulmonary function, and pulmonary strength between normal children and children with CP by using ultrasonography M-mode. The correlation between general characteristics, diaphragm movement, pulmonary function, and pulmonary strength was also studied. Methods: The subjects of this study were 25 normal and 25 CP children between five and 14 years of age. Diaphragm movement was measured using real-time ultrasonography during quiet and deep breathing. Pulmonary function (such as forced expiratory volume in one second; FEV1 and peak expiratory flow; PEF) and pulmonary strength (such as maximum inspiratory pressure; MIP and maximum expiratory pressure; MEP) were measured. A paired t-test and Spearman's Rho test, with a significance level of .05, were used for statistical analysis. Results: The between-group comparison revealed that normal children had significantly greater diaphragm movement, FEV1, PEF, MIP, and MEP (p<.05) than CP children. The results showed that general characteristics were significantly related to FEV1, PEF, MIP, and MEP (p<.05). Conclusion: In clinical settings, clinicians need to concern decreased diaphragm movement, pulmonary function, and pulmonary strength in CP group compared to normal children.

The purpose of this study was to evaluate the mandibular movements of TMD patients comparing to normal persons. Sirognathograph was used to measure five parameters of mandibular movements of twenty normal persons and eight TMD patients. Five parameters were (1) Maximum opening during maximum opening and closing, (2) Mean velocity during maximum opening and closing, (3) Maximum opening during unilateral chewing, (4) Mean velocity during unilateral chewing, (5) Consistency of mandibular movement during unilateral chewing. Based on above results, new Mandibular Movement Index(M.M.I.) was formulated and compared to Helkimo's Clinical Dysfunction Index by measuring two indices before treatment and 2 weeks, 4 weeks, 6 weeks, 8 weeks after treatment. The conclusions were as follows: 1, The amounts of maximum opening and mean velocity during maximum opening and closing of TMD patients were less than those of normal persons(p<0.01). 2. The amounts of maximum opening and mean velocity during unilateral chewing of TMD patients were less than those of normal persons(p<0.05) (P<0.01). 3. Although TMD patients showed limited mandibular movements during unilateral chewing, the consistency of mandibular movements was better than that of normal persons(p<0.05). 4. Both mandibular movement index and Helkimo's Clinical Dysfunction Index, were useful in diagnosing TMD patients.

Proprioception means the ability to perceive the sensation of position and movement of body. As it is transmitted to central nervous system and used in feed-back or feed-forward motor control, proprioception allows us to keep our normal movement and normal balance activity. However, the conditions such as injury, disease, aging and fatigue can damage the proprioceptiive sensation of position, movement and lead to a functional impairment and additional damages in musculoskeletal system, because they alter the amount of proprioceptive ability that transfer into the central nervous system. The purpose of this study was to identify the definition and the function of proprioception, to look into variations in injury, disease, aging and fatigue that can be easily met in clinical application and eventually to provide valuable aid for assessment and treatment.

This study was undertaken to find out oropharyngeal movement of the class III malocclusion patients during swallowing by using the cinefluoroscopic method. The experimental group was composed of fifteen male adults with class III malocclusion whose mean age was 24.4 yrs. The control group was composed of fifteen male adults with normal occlusion whose mean age was 24.8 yrs. The results were as follows: 1. The horizontal position of the tongue tip was more anterior in the class III malocclusion group than in the normal group through all stages. 2. The tongue level was lower in the class III malocclusion group than in the normal group during stage 1, stage 3, and stage 4. 3. The horizontal position of the hyoid bone was more anterior in the class III malocclusion group than in the normal group during stage 1 only. 4. The tip of the soft palate was lower in the class III malocclusion group than in the normal group during stage 1 only, and there was no significant difference in the velar movement between the class III malocclusion group and the normal group during swallowing. 5. There was a significant difference in the interincisal distance, but no significant difference in the intermolar distance between the class III malocclusion group and the normal group through all stages. 6. Among 4 stages of each group, there was a significant difference in the movements of the dorsum of the tongue, the hyoid bone, and the soft palates And there was a significant difference in the movement .of the tongue tip of the normal group, but no significant difference in the movement of the tongue tip of the class III malocclusion group.

The baby makes very great strides in the first year of his life. The developmental principles may be summarised as follows : first, the continuous process from conception to maturity, second, the physical manifestation of neural maturation, third, the cephalocaudal direction, from proximal to distal, fourth generalized mass activity to specific individual responses, fifth, reflex dominance to integration. The stages of normal movement development an head control, rolling creeping(on belly), sitting crawling(on hands and on knees), standing and walking. The knowledge of normal movement development needs for the assessment treatment and management of C.N.S. injuried infant.
