  • It is clinically important to determine the physiologic mandibular position as the therapeutic position of the patients who needs the oral rehabilitation and occlusal treatment. Several methods have been employed for the recording the mandibular position. The gothic arch tracer is one of methods to record the mandibular position. The purpose of this study is to record the border position, chewing position, and myocentric position using the newly developed intra oral tracer in 10 subjects with TMJ clicking sound and 10 subjects without TMJ clinking sound.. This study showed that newly developed intra oral tracer allowed clinician the determination of the treatment position on the same horizontal plate which can be used in the full mouth rehabilitation and occlusal treatments. There was no statistically significant difference between clicking group and nonclicking group in the distance of border position-chewing position and the distance of border position-myocentric centric position.

  • Pregnancy and puerperium are associated with significant changes in pschological and physiologic health status. Back and pelvic pain is common in pregnancy with prevalence figures in the range of $48\%-90\%$. The pain starts during pregnancy and often disappears soon after childbirth. But the prevalence of such pain four to six months post postpartum is report to be $25-40\%$. In $10-15\%$ of the case the pain become chronics, that is persisting for more than three months after childbirth. Low back pain and pelvic pain maybe caused by several factors related to changes that occur naturally during pregnancy. Changes in the center of gravity can create a strain on weight-bearing structures in bone. Pregnancy related hormones, relaxin, create general laxity of collagenous tissue. Another factor found to be a possible primary or contributing cause for law back and hip symptoms are leg length inequality, weight gain and changes in foot function. This article outlines the physiological and biomechanical changes that occur during pregnancy which have been reported to be possible causes of low back and pelvic pain And then, examination, diagnosis, evaluation and treatment of the woman during pregnancy are described. Standard treatment for low back pain and pelvic pain in pregnancy includes education in anatomy and kinesiology, back-strengthening exercise, training of the abdominal muscles and body posture correction. So, most woman during pregnancy require individual consultation and physiotherapist.

  • Objectives : This study was done to investigate the formation process of the 'The Spleen controls the blood(脾統血)' concept, to clarify what this concept means and the mechanism of its physiology. Methods : Contents including 'Controlling blood(統血)' and 'Binding blood(攝血)' were searched and analyzed in medical classics. Previous researches were applied. Results & Conclusions : The concept of 'Controlling blood' could be defined as the control of blood movement. This means that it sends blood to where it's needed, and inhibits flow from where it's excessive. 'The Spleen controls the blood' was not used as a physiologic term in early books like Huangdineijing(黃帝內經). It was first used in the 13C, then widely after the 16C. The mechanism of 'Controlling blood' could be classified as the function of 'Production', 'Distribution', and 'Adjustment' of blood. 'Production' of blood can reduce blood fever(血熱) and blood stasis(瘀血), and prevent bleeding. 'Distribution' of blood can reduce the symptoms raised by lack of blood in the five viscera and body. 'Adjustment' of blood means maintaining homeostasis and stability of the human body. Pi can adjust blood flow and prevent blood from being imbalanced.

  • 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.

  • Sleep is a vital, highly organized process regulated by complex systems of neuronal networks and neurotransmitters. Normal sleep comprises non-rapid eye movement (NREM) and REM periods that alternate through the night. Sleep usually begins in NREM and progresses through deeper NREM stages (2, 3, and 4 stages), but newborns enter REM sleep (active sleep) first before NREM (quiet sleep). A period of NREM and REM sleep cycle is approximately 90 minutes, but newborn have a shorter sleep cycle (50 minutes). As children mature, sleep changes as an adult pattern: shorter sleep duration, longer sleep cycles and less daytime sleep. REM sleep is approximately 50% of total sleep in newborn and dramatically decreases over the first 2 years into adulthood (20% to 25%). An initial predominant of slow wave sleep (stage 3 and 4) that peaks in early childhood, drops off abruptly after adolescence by 40% from preteen years, and then declines over the life span. The hypothalamus is recognized as a key area of brain involved in regulation of sleep and wakefulness. The basic function of sleep largely remains elusive, but it is clear that sleep plays an important role in the regulation of CNS and body physiologic processes. Understanding of the architecture of sleep and basic mechanisms that regulate sleep and wake cycle are essential to evaluate normal or abnormal development of sleep pattern changes with age. Reduction or disruption of sleep can have a significant impact on daytime functioning and development, including learning, growth, behavior, and emotional regulation.

  • Purpose: The purpose of this study was to test a hypothetical model of chemotherapy-related cognitive impairment (CRCI) and depression in people with gastrointestinal cancer. Methods: A purposive sample of 198 patients undergoing chemotherapy was recruited from November 2014 to July 2015. The instruments were Everyday Cognition (ECog), Hospital Anxiety Depression Scale (HADS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), and M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module. Data were analyzed using descriptive statistics, correlation, and path analysis. Results: CRCI was directly affected by cancer symptoms (${\beta}=.19$, p=.004) and fatigue (${\beta}=.56$, p<.001)($R^2=47.2%$). Depression was directly affected by fatigue (${\beta}=.48$, p<.001) and CRCI (${\beta}=.27$, p<.001). However, The impact of cancer symptoms on depression was confirmed through the mediating effect of CRCI. Conclusion: Results indicate that in patients with gastrointestinal cancer undergoing chemotherapy along with the direct physiologic effects (fatigue, symptoms) of cancer treatment may have altered cognitive function leading to depression.

  • Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.

  • Recent studies have focused on evidence-based interventions to prevent mobility decline and enhance physical performance in older adults. Several modalities, in addition to traditional strengthening programs, have been designed to manage age-related functional decline more effectively. In this study, we reviewed the current relevant literatures to assess the therapeutic potential of eccentric exercises for age-related muscle atrophy (sarcopenia). Age-related changes in human skeletal muscle, and their relationship with physical performance, are discussed with reference to in vitro physiologic and human biomechanics studies. An overview of issues relevant to sarcopenia is provided in the context of the recent consensus on the diagnosis and management of the condition. A decline in mobility among the aging population is closely linked with changes in the muscle force-velocity relationship. Interventions based specifically on increasing velocity and eccentric strength can improve function more effectively compared with traditional strengthening programs. Eccentric strengthening programs are introduced as a specific method for improving both muscle force and velocity. To be more effective, exercise interventions for older adults should focus on enhancing the muscle force-velocity relationship. Exercises that can be performed easily, and that utilize eccentric strength (which is relatively spared during the aging process), are needed to improve both muscle force and velocity.

  • Temporomandibular joint(TMJ) ankylosis is characterized by the formation of bony or fibrous mass, which replaces the normal articulation. Ankylotic block formation causes reduction of mandibular mobility, particularly hindering mouth opening, due to a mechanical block of the condylar head in its roto-transfatory motion. Surgery in TMJ ankylosis treatment entails complete ankylotic block removal and subsequent arthroplasty, possibly with autologous tissue between articular surfaces or heterologous material to restore the anatomic structure and normal function. Temporalis myofascial flap holds great promise for the reconstruction of various maxillofacial defects. In more recent years, a pedicled temporalis myofascial flap has been advocated in TMJ ankylosis surgery. Advantages of the temporalis myofascial flap in TMJ reconstruction include close proximity to the TMJ, adequate blood supply from the internal maxillary artery, and its attachment to the coronoid process, which provides movement of the flap during function, simulating physiologic action of the disc. This study evaluated 8 patients(11 TMJs) affected by TMJ ankylosis. All patients underwent surgical treatment of the removal of the ankylotic block and subsequent interpositional arthroplasty with temporalis myofascial flap. Bilateral TMJ ankylosis was observed in 3 patients(6 TMJs), right-sides in 3 patients, left-sided in 2 patients. Epipathogenesis was traumatic in 6 patients(8 TMJs), ankylosing spondylitis in 2 patients(3 TMJs). In 3 patients coronoidotomy was underwent. Average follow-up was 16.8 months after surgery, with a range of 7 to 28 months. No patients underwent additional TMJ procedures after the temporalis myofascial flap. All patients showed a distinctive improvement both in articular functionality and symptoms. We found that temporalis myofascial flap is very valuable in reconstruction of TMJ ankylosis.
