Magneto-Rheological (MR) fluid is suspension of fine magnetic particles in a liquid carrier such as silicon oil or water. MR fluid exhibits solid-like mechanical behavior into chain or clusters with high yield stress when magnetic field is applied to the particles. The response of MR fluids is very quick and reversible after removal of the field. MR Fluids have high yield stress (up to 5kPs) and operate in low voltage power supply. Recently, MR damper using MR fluids was open used in vibration control system such as structural devices, seat vibration controllers and helicopter rotor systems, but it is too big in size and heavy. Therefore, it is not appreciate to rehabilitation devices such as prosthetic limbs.

Radiation recall is an uncommon phenomenon in which administration of a chemotherapy or another systemic agent induces an acute inflammatory reaction in previously irradiated tissues, often weeks to years after completion of radiotherapy. Gemcitabine can induce an inflammatory reaction within an area of prior radiation. Radiation recall is known to medical oncologists, however only few cases have been reported in Korean journals, therefore physiatrist who diagnose and treat the treatment-related physical impairments of cancer patients must know about it. We emphasize the importance of knowledge of this phenomenon when considering the differential diagnosis of painful limb edema in a patient who has received cancer treatment.

In cases of hyponatremia induced by brain damage, it is important to distinguish between the syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and cerebral salt wasting syndrome. A ventriculoperitoneal (VP) shunt is the standard treatment for hydrocephalus, and external lumbar drainage (ELD) is an option to evaluate the effect of a VP shunt. However, ELD has potential complications, such as subarachnoid hemorrhage, meningitis, and rarely hyponatremia. Therefore, we report a case of a patient with cerebral salt-wasting syndrome resulting from ELD to treat normal-pressure hydrocephalus during the rehabilitation of acute ischemic stroke.

A cryotherapy system using the low temperature air was developed. The developed cryotherapy system had superior low temperature characteristics and many safety devices. For a clinical evaluation, skin and intra-articular temperatures of the knee joint were measured during and after the cryotherapy. After 5-minute therapy, skin and intra-articular temperature decreased by $23.3{\pm}4.7(^{\circ}C)$ and $4.1{\pm}1.0(^{\circ}C)$ respectively. A 5-minute cryotherapy therapy is good enough to maintain low intra-articular temperatures or 2-3 hours.

The aim of this study is to design and develop the gait rehabilitation equipment that judge patient's movement of his/her center of gravity using pressure sensors, and to aid hemiplegic patients to balance themselves using an automatic stepper that changes the patient's center of gravity. It is hard to bear the weight on the affected side for hemiplegic patients. The gait rehabilitation equipment detects the footing phase of hemiplegic patient during training and moves the unaffected footing side of the stepper up and moves the affected footing side down simultaneously so that the patient's center of gravity can shift from unaffected side to affected side. The gait rehabilitation system was developed and applied for hemiplegic patients during exercise. Eight hemiplegic patients and one normal adult were studied. The developed gait rehabilitation system could judge not only the normal adult's intention but also the patient's intention to move his/her center of gravity. Even though the most of hemiplegic patients exercised in automatic mode and a few hemiplegic patients exercised in manual mode, the developed gait rehabilitation system can aid the hemiplegic patients to train more easily.

Tetrasomy 18p is a genetic syndrome caused by an isochromosome consisting of two copies of the short arm of chromosome 18. Clinically, pediatric cases of tetrasomy 18p manifest with global developmental delay, similar to most cases of chromosomal abnormality. In addition, it causes various symptoms including abnormal muscle tone. We report a case of an infant with global developmental delay and remarkable spasticity, the typical phenotype of bilateral spastic cerebral palsy. However, she had a subtle anomaly in her face, and brain magnetic resonance imaging (MRI) findings were inconsistent with her strong upper motor neuron signs. Upon genetic testing, she was determined to have an 18p isochromosome, confirming de novo non-mosaic tetrasomy 18p. Cerebral palsy is a neurological disorder that includes developmental delay caused by a non-progressive lesion in the developing brain. During diagnostic workup in patients with cerebral palsy, genetic testing should be considered when there are minor physical anomalies or equivocal MRI findings.

Background: The purpose of this study was to analyze the associations between physical therapists' work-related musculoskeletal pain, quality of life (QoL), and presenteeism. Methods: Self-reported questionnaires were given to 402 physical therapists in Korea. Variables examined included the prevalence of pain sites related to work, pain intensity, pain pattern, pain frequency, pain duration, pain rating score (PRS), general characteristics, QoL, and presenteeism. Results: Of the 314 physical therapists who responded, 251 (79.9%) reported work -related musculoskeletal pain in at least one body part. The most affected regions included the wrist and hand (21.0%), shoulder (19.6%), and lower back (19.1%). On average patients, QoL and presenteeism differed significantly between physical therapists who reported pain and those who did not (P < 0.05). QoL showed a negative correlation with the work-related musculoskeletal pain (P < 0.01) and presenteeism (P < 0.01), while the presenteeism and work-related musculoskeletal pain showed positive one(P < 0.01). Factors influencing a physical therapist's QoL included presenteeism, Working venues (Convalescent hospital), Work status (Contra ct worker) and professional experience, while the presenteeism included QoL, work status (Intern), PRS, working venues (Convalescent hospital), Area of specialty (Pediatrics), age, sex and working hour. Conclusions: Results show that physical therapists appear to be at a higher risk for work-related musculoskeletal pain. Therefore, administrators need to use the intervention strategies to manage the presenteeism and QoL of physical therapists.

Objective : The purpose of this study was survey about the recognition and demand on cooperative system between western and oriental medicine of stroke patients in National Rehabilitation Center. Methods : The participants were 205 stroke patients in the National Rehabilitation Center and investigated the recognition and demand on cooperative system between western and oriental medicine. Results : As to general characteristics of the group, 56.9% were male, 30.7% were in the 60~69 age, 24.3% of patients had an average income per month 1.0~2.0 million. In regard to disease status of patients, 53.8% were cerebral infarction, 35.8% were below 6 month in disease duration, 73.7% were none recurrence, 52.8% were hypertension as related disease, 74.5% were motor paralysis sequela. 83.2% were positive response in using oriental medicine department of National Rehabilitation Center. The most wanted therapy was acupuncture. Most of respondents expected that co-operative treatments were to be improving the cure effect for patients. And they wanted cooperative system combined evenly between western and oriental medicine, so the western doctors and the oriental doctors suggest the plan giving lots of medial benefits for patients. Conclusion : This survey showed the recognition and demand on cooperative system between western and oriental medicine of patients in National Rehabilitation Center. It is possible to realize patient's centered treatment under the stable and efficient cooperation of western and oriental medicine.

Purpose: This study aimed to investigate the effect of an intensively rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. Methods: In this study, the anonymized electronic medical records of individuals who participated in the intensive rehabilitation program (among those who were admitted to the hospital belonging to the Labor Welfare Corporation) due to an industrial accident from August 2018 to September 2019 were collected. As a result, the records of 12 subjects meeting the screening criteria were analyzed. Results: According to the time of application to the intensive rehabilitation program, the 10 Meter Walk Test (10MWT) (p < 0.01), Berg Balance Scale (BBS) (p < 0.01), Timed Up and Go Test (TUG) (p = 0.01), the L Test of Functional Mobility (L-test) (p < 0.01), Prosthetic Limb Users Survey of Mobility (Plus-M) (p < 0.01), and Houghton Score Question (HSQ) (p < 0.01) values significantly improved with time. Conclusion: This study confirmed the positive effect of an intensive rehabilitation program on the gait, balance, functional performance, and wearing satisfaction of patients with traumatic lower extremity amputations caused by industrial accidents. However, this study was limited by the absence of a control group, and, thus, it highlights the need for more extensive research with a large sample.

Background: We aimed to provide basic data for improving the effectiveness of the invitational training and reflecting it in the program in the following year by identifying the satisfaction level of trainees who participated in the "Dr. LEE Jong-wook Fellowship Program" funded by the Korea Foundation for International Healthcare. Methods: A qualitative study was conducted using a questionnaire interview. In the first stage of analysis, only the interview contents related to the research topic were classified by the researcher for the conversations recorded at the interview site, and in the second stage of analysis, the interview contents classified in the first stage were classified into each of those mentioned in this study. Results: The longer the trainees participated in the program and the better the accessibility, the higher the satisfaction with the program. In addition, the level of achievement of the trainees' goals and the level of improvement in their competence affected their satisfaction, and their difficulty in language communication during the training period was identified as a factor affecting the trainees' satisfaction level. In addition, competency improvement and satisfaction were positively correlated (r=0.75, p=0.03). Conclusion: When organizing a rehabilitation workforce capacity training program, it is important to identify trainees' needs, ensure accessibility, organize courses effectively, enhance English proficiency, and expand practical lectures to increase trainees' knowledge and understanding of rehabilitation.
