In modem city life, the citizen get insufficient exercise and has high levels of stress. Increased Stress causes such minor things as tiredness, disease and mental fatigue, and increase brain blood pressure too. In this paper trying to design the multi-functional blood pressure monitor with airo-dynamic brain hemokinesis improvement function. So this system have developed for the improvement of flows in the capillary blood vessel of head and limbs. Also This system is able to measure brain blood pressure(BBP) which need diagnosis circulation state of brain blood. So, we extracted correlativity of blood pressure(BP) and BBP through clinical experiment. We confirmed that compare factor of BP with BBP is more useful factors for diagnosis state of brain hemokinesis.

Extravasation injury refers to leakage of corrosive liquids from veins, resulting in tissue damage. The authors report on a case of extravasation injury to the left hand after administration of fluid to the antecubital area in a patient with brain damage. In order to minimize the effects of extravasation injury, rapid diagnosis and management are needed. In patients with stiffness, pressure sores can develop requiring more careful management by the medical staff.

대뇌혈류증가 치료는 뇌경색에 가장 중요한 치료방법중 하나이다. 기존의 대뇌혈류증가 치료가 침습적으로 행해져옴에 따라 다수의 합병증을 유발할 수 있다는 문제점이 제기되고 있다. 따라서 이러한 문제점을 보완하기 위해 최근에는 비침습적 대뇌혈류증가 장치가 등장하였다. 하지만 현재 구현된 비침습적 대뇌혈류증가 장치는 속도와 정확성이 떨어지는 문제점이 제기되고 있다. 본 논문에서는 기존의 구현된 비침습적 대뇌혈류증가 장치의 단점을 보완하고자 다른 방식으로 시스템을 구현하여 대뇌 부위로 가는 혈류량을 우회적으로 증가시켜 최종대뇌 손상부위를 최소화 하는 것으로 목표로 한다. 본 논문에서 구현한 시스템은 사지압박을 진행함과 동시에 사지의 혈류지수를 측정하여 혈류지수가 일정 수치 이하로 떨어지는 압력을 찾아 사지압박을 통해 대뇌부위로 가는 혈류량을 우회적으로 증가시켜 혈류증강 치료를 실시한다. 이는 기존의 침습적 대뇌혈류증가 치료와 비교하여 합병증의 우려가 없고, 최종실험 결과 혈류량을 20% 이상 증가시키기에 환자에게 선택적으로 사용될 수 있다.

Microsurgery has advanced beyond its nascent stages reaching success rates of 90% to 95%. However, this means that even in the best circumstances, 5% to 10% of free flaps and replants fail. Almost all failures are due to vessel thrombosis, resulting in ischemia of the transplanted tissue. Many attemps have been undertaken to treat and reverse its effects. Zdeblick and colleagues noted an improvement in the viability of amputated limbs replanted after an extended period of ischemia following intraarterial infusion of urokinase. Subsequent studies have investigated many modalities of urokinase administration in various animal models by differing ischemic periods. These studies, however, have failed to establish a definitive, generally accepted protocol for administration of urokinase in the salvage of tissue subjected to prolonged ischemia. Our clinical observations suggest that a bolus of urokinase delivered under pressure may increase the thromoblytic effect of the drug, probably by means of increased delivery to microvasculature. We intend to investigate the role of selective pressure perfusion of ischemic flaps as a new means for increasing the effectiveness of urokinase in the treatment of the "no-reflow" phenomenon. A total of 32 male New Zealand rabbits were used and divided into the four groups according to the method of infusion. After 12 hours of ischemia the flaps were injected with Hartmann's solution or with urokinase and the percent survival of the flap was determined at 7 days following flap reperfusion. As the result, the flap survival rate was highest in the pressure injection of urokinase group.

Purpose : To evaluate the effects of elastic resistance exercise of lumbo-pelvic region and upper limbs muscle on equilibrium ability and shoulder pain of the elderly. Methods : The subject consisted of sixteen healthy elderly people(14 females. 2 males). They were from 61 to 83 years old and the mean age was 68.06. All subjects were assigned only the elastic resistance exercise group. The subject group received elastic resistance exercise for about 60 minutes per day, two times per weeks, during 8 weeks period. A Stop watch was used to measure static equilibrium ability and dynamic equilibrium ability and then pressure algometer was used to measure shoulder press pain threshold. All measurements of each subjects were measured at pre-experiment and post-experiment stage. SPSS 12.0 program was used to compile results. A Paired samples t-test was conducted to examine changes of static equilibrium, dynamic equilibrium and shoulder press pain threshold between pre-experiment and post-experiment. Results : The static equilibrium ability, dynamic equilibrium ability and shoulder press pain threshold were significantly differences between pre-experiment and post-experiment(p<.05). Conclusion : This data suggests that an eight week elastic resistance exercise improved static equilibrium ability and dynamic equilibrium ability and then reduced shoulder pain.

Objective: Persons with stroke have a tendency to exhibit asymmetric weight-bearing during sit-to-stand because due to the attempt to support themselves with the non-paretic foot. However, there are few devices that can assist with sit-to-stand (STS) performance. This study was designed to investigate the use of the elastic band with rings (EBR) in improving weight-bearing effectively in persons with stroke during STS training. Design: Cross-sectional study. Methods: Thirteen stroke survivors participated in the study. An EBR was applied onto the patient during STS activity. The foot pressure was measured before and after wearing the EBR, with a 5-minute rest period between measurements. Subjects were asked to perform each test twice with and without the EBR. Bilateral feet pressures were measured with standing posture being divided into the forward and backward aspects. The foot contact pressure during STS activity was measured with the CONFORMat System. Results: With EBR, the forward pressure of the affected foot significantly increased while the less-affected forward foot pressure significantly decreased (p=0.015 and p=0.023, respectively). The backward foot pressure did not differ significantly in the two limbs, and there was no difference with and without the EBR in terms of the total pressure of the affected foot. There was a significant difference with and without the EBR in the total pressure of the less-affected foot (p<0.05). Conclusions: STS training with the EBR has been shown to improve weight-bearing of both feet while decreasing the total pressure of the less-affected foot in stroke survivors. Therefore, we suggest that the EBR is a useful tool for STS training for persons with stroke in the clinic.

In this paper, we propose a stress analysis on foot by lifting task attitudes. Maximum force and peak pressure were measured on 8 body regions by Pedar system in order to analysis the stress which is affected by task style and angle on foot when Manual Materials Handling task. As for the peak pressure of the whole foot as to the task height during the lifting task, the height from Knuckle to Shoulder was the least in the peak pressure. Also, as for the maximum force and the peak pressure of the whole foot as to the task angle during the lifting task, it could be seen that the more an angle increases, the stress influencing on a foot jumps. As for the maximum force and the peak pressure by foot region as to the task height in case of the lifting task, the height from Knuckle to Shoulder is indicated the smallest value in the maximum force and the peak pressure, thus there is necessary to attain the work design that considered this. Also, as for the maximum force by foot region as to the task angle in case of the lifting task, 0° tasking is indicated to be least, thus there is necessity to be attained the tasking design in a bid to prevent the existence of an angle. The results of this paper are thought to be helpful to the suitable work design, to the prevention of musculoskeletal disorders related to the lower limbs, and to the design of ergonomic safety shoes.
