Acute transverse myelitis(ATM) is defined as an acute intramedullary dysfunction of the spinal cord, ascendng or static involving both halves of the cord and appearing without any history of previous neurological diseases due to traumatic accident, tumor of all kind, encephalitis and of course excluding all possible viral, bacterial and fungal infection. It is mainly characterized by acute motor disorder of both limbs in respect to which spinal segments are affected as well as sensory disorder and dysuria & dyschezia. The exact cause is unknown, however it is recently suggested that immunological factors are highly involved. It has been reported by several reliable sources that it is often accompanied by immunological diseases such as systemic lupus erythematosus(SLE). As treatments non steroid anti-inflammatory drugs(NSAIDS) are primarily recommended as to steroids, limited doses are injected only with the proper prescription from the physician. Operative methods are not options as traumatic accidents and tumors are excluded as factors. To enhance muscle strength and prevent articular contracture physical therapy and passive exercise is imperative. The following patient whose chief complaints were mainly about hypoesthesia of Rt. lower limb and stiffness of phalanges of both fingers as well as to weakness of lower extermity. Therefore it has been diagnosed as arthalgia syndrome. In oriental medicine factors such as wind evil heat-evil, dampness-heat evil, cold evil cause the arthalgia syndrome. In this case the patient was diagnosed as dampness-heat evil and herbal medicine Chunglijagam-Tang and Dong-Qi acupuncture was applied to treat bladder disorder.

The purpose of this study was to compare pregnant women's gait parameters and mechanical energies caused by changes in hormone levels and anatomical features such as body mass, body-mass distribution, joint laxity, and musculo-tendinous strength from pregnancy to postpartum. Ten subjects (height: $161{\pm}6.5cm$, mass: $62.7{\pm}10.4\;kg$, $66.4{\pm}9.3\;kg$, $68.4{\pm}7.7\;kg$, $57.2{\pm}7.7\;kg$) participated in the four times experiments (the first, middle, last term and after birth) and walked ten trials at a self-selected pace without shoes. The gait motions were captured with Qualisys system and gait parameters were calculated with Visual-3D. Pregnant women's gait velocities were decreased during the pregnancy periods, but increased after birth. Stride width and cycle time were increased during pregnancy, but decreased after birth. Thigh energy (77.4%) was greater than shank energy (19.06%) or feet (3.54%) about total energy of the lower limbs. Their feet (Left R2=0.881, Right R2=0.852) and shank (Left R2=0.318, Right R2=0.226) energies were significantly increased (positive correlation), but double limb stance time (DLST, R2=0.679) and body total energy (R2=0.138) were decreased (negative correlation) for their velocities. These differences suggest that thigh segment may be a dominant segment among lower limbs, and have something to do with gait velocities. Further studies should investigate joint power and joint work to find energy dissipation or absorption from pregnancy period to postpartum.

The purpose of this study was to evaluate the gender differences on gait pattern and the kinetics on lower extremities according to the different gait speed. Ten collegiate male students (age : $23.80{\pm}2.94$ yrs, height : $179.40{\pm}5.04$ cm, weight : $66.57{\pm}5.64$ kg) and ten female students (age : $23.40{\pm}2.91$ yrs, height : $166.06{\pm}5.61$ cm, weight : $53.76{\pm}2.75$ kg) participated in this study. To investigate the role, the ratio of the use, and the effectiveness of each joint during gait, we examined the joint work and the contribution to total work. The results of this study were as follows: First, gait pattern was not differ between male and female, hip joint ROM increased with the increase of gait speed both male and female. Second, the eccentric work of the ankle joint decreased with the increase of the gait speed both male and female, on the other hand increased on the knee joint. Third, in the result of the contribution to total eccentric work, male in both the two gait speed was the biggest on the hips joint. However, female in normal gait speed was the greatest on the ankle joint, was the most on the knee joint in the fast gait speed. Forth, the concentric work on the ankle and hip joint increased with the increase of gait speed both male and female. Fifth, in the result of the contribution to total concentric work, there is no difference in the male both the two gait speed, however decreased in the female on the knee joint with the increase of the gait speed, on the other hand increased on the ankle joint.

Purpose: Blue toe syndrome consists of blue or purplish toes in the absence of a history of obvious trauma, serious cold exposure, or disorders producing generalized cyanosis. It is a life-threatening and still underrecognized disease. It can be commonly occurred by vascular surgery, invasive cutaneous procedures or anticoagulant therapy. Our case is presented of blue toe syndrome related to atheromatous embolization that was presumably triggered by angio CT. Methods: A 69-year-old man presented with the suddenly developed pain, cyanosis and livedo reticularis of the toes in right foot. Dorsalis pedis pulses were palpable. He had been performed a diagnostic angio CT 1 month earlier. Angio CT revealed diffuse aortic atheromatous plaque in lower abdominal aorta and both common iliac artery. One month after angio CT, he visited our clinic. There was no visible distal first dorsal metatarsal artery and digital artery of right first toe in lower extremity arteriography. A diagnosis was established of blue toe syndrome. Because his symptom was aggravated, we performed the exploration of the right foot. After exposure of first dorsal metatarsal artery, microsurgical atheroembolectomy was done. Results: There were no postoperative complications. After three months the patient had no clinically demonstrable problems. Conclusion: Patient with blue toe syndrome is at high risk of limb loss and mortality despite treatment. Blue toe syndrome produces painful, cyanosed toes with preserved pedal pulses. It needs to be aware of blue toe syndrome. Careful history should reveal the diagnosis. Treatment is controversial, however, most believe that anticoagulation therapy should be avoided.

Objective: The purpose of this systematic review and meta-analysis was to investigate age-related bimanual coordination functions in older adults. Method: Thirteen studies that compared bimanual coordination functions in older adults with those in healthy young adults qualified for this meta-analysis. We additionally categorized 21 total comparisons from the 13 qualified studies into two types of task-related moderator variables: (1) kinematic versus kinetic movements and (2) symmetry versus asymmetry movements. Results: Random effects model meta-analysis found that older adults revealed significant bimanual coordination impairments as compared with young adults (Hedges's g = -0.771; p < .0001; I² = 74.437%). We additionally confirmed specific bimanual coordination deficits using two moderator variables: 1) kinematic (Hedges's g = -0.884; p < .0001; I² = 0.000%) and kinetic (Hedges's g = -0.666; p = .023; I² = 86.170%). 2) symmetry (Hedges's g = -0.712; p = .001; I² = 74.291%) and asymmetry (Hedges's g = -0.817; p < .0001; I² = 76.322%). The moderator variable analysis indicated older adults indicated bimanual coordination deficits in the upper extremities than healthy young adults while performing kinematic bimanual coordination tasks and asymmetry coordination tasks. Conclusion: These findings suggest that developing motor rehabilitation programs based on asymmetric bimanual movement task for enhancing interlimb coordination functions of older adults may be crucial for increasing their independence in everyday activities. Given that elderly revealed the deficits in lower extremities coordination when older adults perform gait, posture, and balance, future studies should estimate lower limb coordination functions in elderly people.

Objective: The purpose of this study was to investigate the effects of eccentric contraction training (ECT) and concentric contraction training (CCT) on the muscle thickness (MT), muscle strength (MS) and delayed onset of muscle soreness (DOMS) of the lower extremities in persons with chronic stroke. Design: Randomized controlled trial. Methods: Thirty persons with chronic stroke were randomly assigned to the ECT or the CCT group. The ECT was performed in a specially designed system of eccentric contraction of both legs and, the CCT was performed using a traditional stepper system for concentric contraction of both legs. The training was performed for 30 min/times, 3 times/wk for 6 weeks. Rehabilitation ultrasound imaging was used to measure MT of the vastus medialis/lateralis (VL), and soleus (SOL), a digital muscle tester was used to measure MS, and a visual analog scale was used to assess DOMS. Results: In the ECT group, MT was significantly improved except for SOL resting (p<0.01). In the CCT group, the MT was significantly improved except for VL contraction (p<0.05). The MS was significantly improved in both groups, especially in the ECT group (p<0.01). In the ECT group, muscle soreness was highest in the first week after training but gradually decreased, and in the CCT group, it was highest in the second week of training but gradually decreased (p<0.01). Conclusions: ECT can improve lower limb MT, MS, and DOMS of chronic stroke survivors. Therefore, it is recommended that ECT be used in the rehabilitation of persons with chronic stroke.

This study measured the downward stepping movement relative to weight change (no load, and 10%, 20%, 30% of body weight respectively of adult male (n=10) from standardized stair (rise of 0.3 m, tread of 0.29 m, width of 1 m). The 3-dimensional cinematography and ground reaction force were also utilized for analysis of leg stiffness: Peak vertical force, change in stance phase leg length, Torque of whole body, kinematic variables. The strategy heightened the leg stiffness and standardized vertical ground reaction force relative to the added weights (p<.01). Torque showed rather larger rotational force in case of no load, but less in 10% of body weight (p<.05). Similarly angle of hip joint showed most extended in no-load, but most flexed in 10% of body weight (p<.05). Inclined angle of body trunk showed largest range in posterior direction in no-load, but in vertical line nearly relative to added weights (p<.001). Thus the result of the study proved that downward stepping strategy altered from height of 30 cm, regardless of added weight, did not affect velocity and length of lower leg. But added weight contributed to more vertical impulse force and increase of rigidity of whole body than forward rotational torque under condition of altered stepping strategy. In future study, the experimental on effect of weight change and alteration of downward stepping strategy using ankle joint may provide helpful information for development of enhanced program of prevention and rehabilitation on motor performance and injury.

Purpose: Assessing physical strength and muscle mass is crucial, but many methods rely on specialized equipment, which can be challenging. In situations where a quick and straightforward test is needed, the sit-to-stand test (STST) proves useful. Although several studies have investigated STST and muscle mass separately, the actual correlation between these two factors has not been extensively researched. Hence, the objective was to comprehensively investigate the correlations between the different tests. Methods: The study participants consisted of 20 healthy young men in their 20s. In this study, measurements were taken for muscle mass, the five-times sit-to-stand test, the 30-second sit-to-stand test, and the 1-minute sit-to-stand test. The results of each test were analyzed using Pearson's correlation analysis. Results: Although no significant correlation was found between muscle mass and STST, interestingly, significant correlations were observed among the different types of STST. Conclusion: The STST is a rapid and straightforward test used to assess lower limb strength and balance ability in individuals. However, there is a dearth of research on STST conducted in domestic settings. Based on the findings of this study, further research is necessary to establish age- and gender-specific reference values for STST. This will allow its broader application, encompassing not only older adults and patients but also healthy individuals.

Objectives: This study was performed to evaluate the musculoskeletal symptoms of workers treating electronics industry waste at a recycling sorting plant by case survey. Methods: The musculoskeletal symptoms were investigated by conducting a survey targeting workers treating waste from the electronics industry. Through utilizing the ergonomic evaluation techniques such as RULA, REBA, and OWAS, the four tasks were divided into three detailed processes (sorting, movement, loading) and the work of workers was evaluated for a total of 12 processes. Results: As a result of the questionnaire survey on musculoskeletal symptom, 40% of workers answered that they had musculoskeletal disease symptoms, and the symptom sites were hands(30%), legs(20%), arms(10%), and shoulders(5%). Based on the results obtained from analysis through ergonomic evaluation techniques such as RULA, REBA, and OWAS, 75% of them were found to need improvement or follow-up immediately or immediately after the second stage or higher. As compared to REBA and OWAS, the RULA, which evaluates the upper limb in detail, has a higher score, and in the process of sorting and loading relatively light wastes such as paper and plastic, the waist is raised by repeating the work of bowing and stretching. Conclusions: The heavy wastes such as 200L drums were evaluated as having a low load on the elbows and wrists because body action was relatively lower than moving paper and plastic. In addition, the overall load score was evaluated lower in the moving work compared to the sorting or loading process.

The purpose of this study has been conducted to reduce the lower limbs' spasticity of the patients with hemiplegia caused by cerebral stroke of apoplexy and find differences about spasticity effects among each group. The objects of this study covered 24 patients with hemiplgia who are either in the oo hospital in Daegu or under treatment from home to hospital. The objects fall into three groups which are a group of neurological development treatment, a group of functional stimulus treatment and a group of neurological development treatment and functional stimulus treatment. The result of this study were as follows : 1) The neurological development treatment has been found to reduce the lower limbs' spasticity of patients with hemiplegia caused by cerebral stroke of apoplexy and compared to before-treatment, the MAS value of spasticity has been shown to be statistically meaningful ,and gradually over the period of between 4 weeks and 8 weeks(P <.05). 2) The functional electric stimulus treatment has been shown to reduce the lower limb's spasticity of patients with hemiplegia caused by cerebral stroke of apoplexy and compared to before-treatment, the MAS value of spasticity was statistically meaningful and compared to 4 weeks, even at the time of 8 weeks, the MAS value of spasticity have shown statistical meaningness. (P <.05) 3) When neurological development treatment and functional electric stimulus treatment was applied at the same time, the lower limbs' spasticity of patients with hemiplegia was reduced meaningfully(P <.05). Compared to before-treatment at the time of 4 weeks, the MAS value of spasticity was statistically meaningful and compared to 4 weeks at the time of 8 weeks the MAS value of spasticity was also statistically meaningful(P <.05) 4) In the case of time-based MAS value of each group, functional electric stimulus treatment reduced the spasticity more meaningfully than neurological development treatment, and the group of same application of functional electric stimulus treatment and neurological development treatment showed better statistical meaningness than functional electric stimulus treatment alone(P <.05) and finally the group of same application of neurological development treatment and functional electric stimulus treatment showed more meaningful difference than neurological development treatment alone(P <.05)
