Conversion disorder is a psychologically produced alteration or loss of physical functioning suggestive of a physical disorder. Conversion symptoms are often superimposed on organic disease and can be overlooked. Psychological techniques are central to the management include the following: avoiding confrontation with the patients; avoiding reinforcement or trivializing the symptoms; reviewing results of tests and exams and creating an expectation of recovery; educating the patient before a treatment is begun; evaluating the patient's emotional adjustment and considering it at a treatment; using caution in labeling the condition; considering referral for psychotherapy; establishing particularly a treatment plan and making a definite treatment program; adjusting patient' s environment; letting participate a family at appropriate time; developing a reinforcement program for a treatment of chronic symptoms; developing a home program for outpatients. Use behavior therapy reinforcement may be helpful with more chronic or resistant symptoms, especially when there is a history of vague or excessive somatic complaints or significant secondary gain.

The purpose of this review was to examine the clinical characteristics of patients who had a diagnosis of Myofascial Pain Syndrome(MPS). Myofascial pain is a painful condition of skeletal muscle characterized by the presence of one or more trigger points. A trigger point(TrP) is a focus of hyperirritability in a tissues. Of the patients with MPS, 21(44.7 %) were male and 26(55.3 %) were female. The mean duration of MPS was 9.6 months for males and 11.3 months for females. Trigger points with associated referred patterns of pain were found in muscles of the post neck(trapezius, infrasupinatus) and in quadratus lumborum muscle. Patients reported increased fatigue(87.2 %), tingling sensation(66.0 %), numbness(66.0 %), tension(55.3 %), anxiety(44.7 %), headache (59.6 %), pilomotor activation(59.6 %).

To find optimum conditions necessary in converting physical properties of any resin into those of others, eleven kinds of HIPS (High-Impact Polystyrene) resins were prepared. First physical properties of eleven samples divided into three groups are analyzed by a torque rheometer (named Plasti-Corder, Model No.: PLD 651) and GPC (Gel Permeation Chromatography), and then optimum conditions on conversion among samples are obtained by calculation from computer simulation so that any sample subjected to each group can show physical properties of other samples in its group. Even though the kind of plasticizer of any sample is different with others in its group, once optimum conditions on conversion among samples are met, it is found that physical properties of any sample are identical or similar to those of others in each group.

In this paper, we planned to see the positive effects of the immersive virtual environment. In particular, the positive effect of presence on physical performance was explored. A total of 25 participants were recruited for this experiment and his/her physical performance was measured by Electromyography (EMG) while they were exercising (rowing), and presence was measured by a self-reported measure. The participants were randomly assigned to experience either a) Virtual Reality (VR) or b) non-VR (2D screen) condition when they played the exergame. The result showed that 1) there was a positive relationship between representation mode and presence and 2) the higher level of presence reinforced the user's physical performance. The limitation of the study and future study were also discussed.

Piriformis syndrome is a common differential diagnosis related to sciatica. The following review provides a concise synopsis of the diagnosis, management, history, and alternatives to diagnosis of piriformis syndrome. A search of the literature for research articles related to piriformis syndrome and associated differential diagnosis of sciatica was conducted. A thorough review of the included articles found that the condition known as piriformis syndrome is over-diagnosed and that potential anatomic and biomechanical variations originating in the pelvic region might be related to the complaint of sciatica. The criteria for diagnosis are based on findings from both physical examination and radio imaging. Piriformis syndrome resembles a variety of clinical conditions; therefore, conduct of future studies should include development of a validated method for evaluation as well as clinical criteria for diagnosis of piriformis syndrome.

The purpose of this study was to investigate the neurophysiological mechanisms, assessment of muscle spasm and treatments that could apply to clinical field. Spasm is a painful pattern of contraction of muscle caused by chronic or acute trauma, excessive tension, or organic disorders. Aside from pain, muscle spasm creates shortenning of muscles and limits motion. Untreated spasm and protective immobility due to pain lead to decreased local blood flow in the muscles and result in a vicious cycle of muscle spasm and paul. The assessment of muscle spasm involve muscle tone assessment, tissue compliance, and joint ROM. Each of these aessessments utilize as a part of the patient's condition Clinical managements involve drug management and physical therapy. Expecially, physical therapy is one of the most important techniques to reduce muscle spasm. Physical therapy includes applying heat and cold, electrical stimulation, massage, and traction. This investigation should entourage phisical therapists to experiment further with various techniques to reduce muscle spasm.

Purpose: This study evaluated of quality of life (QOL) and physical therapy satisfaction (PTS) in caregivers of cerebral palsy children. Methods: Eighty six caregivers in Gwang-ju were examined. The caregivers' QOL was assessed through self-reports using the WHO Quality of Life-BREF (WHOQOL-BREF), and the data was analyzed separately for each of its 5 domains. Physical therapy satisfaction was assessed using a self-reported questionnaire and the data was analyzed separately for the 2 domains. The results were processed by the mean and standard deviation and then verified by ANOVA and a t-test to determine the significant differences in the QOL and PTS. The factors affecting the QOL were processed by logistic regression. Results: Life environment domain of the QOL across the caregivers factors showed a statistically significant difference in age at natal, monthly income and education. The birth order in the cerebral palsy child factor showed a significant difference in the general, physical and emotional domain of the QOL. The PTS showed a significant difference in the delivery of therapy domain and in the birth order and walking condition of the environment domain. Caregivers education was found to be associated independently with the life environment domain of QOL. Conclusion: Because the QOL of caregivers is an important treatment goal for children with cerebral palsy, early family intervention should be considered.

Objective: The aim of this study was to measure the muscle architectural parameters of abdominal muscles in healthy individuals by rehabilitative ultrasound imaging (RUSI) and to investigate their changes after bridging exercise in various environments. Design: Cross-sectional study. Methods: The study included 40 healthy participants (19 men, 21 women). Subjects were randomly allocated to a stable surface group (SG, n=20) or an unstable surface group (UG, n=20). The participants assumed three positions in rest, bridging exercise with knee flexion $60^{\circ}$, and bridging exercise with knee flexion $90^{\circ}$ for the measurement of abdominal muscle thickness by RUSI. For the resting position, the participants held the head neutral in a hook-lying position and the dominant side was measured. For contraction, the participants performed the bridging exercise with the knee joint in $60^{\circ}$ and $90^{\circ}$ of flexion for 10 seconds each. Results: For transversus abdominis, external oblique muscle thickness, within the stable surface group and the unstable surface group, no significant contraction difference was observed in both the $60^{\circ}$ and $90^{\circ}$ bridge exercise conditions. Contraction difference of internal oblique muscle was significantly larger at $90^{\circ}$ than at $60^{\circ}$ within the SG (p<0.05). But within the UG, no significant contraction difference was shown. There was no significant contraction difference between the surface group and the unstable SG at $60^{\circ}$ condition and at $90^{\circ}$ condition in all measured muscles. Conclusions: The contraction difference is different for each muscle during bridge exercise with knee flexion $60^{\circ}$ and bridging exercise with knee flexion $90^{\circ}$. Muscle contraction difference is generally large when exercised on an unstable surface than a stable surface, but these are not statistically significant when bridging exercise is performed using dynamic air cushion for unstable surface.
