Purpose: This study investigated the effects of changing the tilt angle of the exercise bed on physiological characteristics of trapezius, multifidus, and hamstring muscle function. Methods: Twenty elderly who complains of back and lumbar pain or discomfort participated in this study (average age: $64.70{\pm}4.55$ years). The physiological characteristics, including muscle tone (F), dynamic stiffness (S), and elasticity (D) of trapezius, multifidus, and hamstring muscles were measured by a Myoton device at three tilt angles (0, 15, and 30 degrees) during exercise. Results: The muscle tone, dynamic stiffness, and elasticity of the right trapezius and left hamstring muscle showed significant differences (p<0.05) according to exercise bed tilt angle, while the other muscles showed no significant differences. Conclusions: Our results demonstrate that physiological characteristics of the upper and lower extremity muscles are affected ipsilaterally, according to the tilt angles of the exercise bed.

Purpose: The aim of study was to identify the effects of exercise on the relief of low back pain in patients on absolute bed rest after TAE. Method: A nonequivalent control group pretest-posttest design research design was used. The participants were 43 patients who had received TAE in a university hospital; patients in the experimental group (21) received both exercise therapy and general post-op nursing care and in the control group (22) only the latter. The exercise program used in this study was modified from exercise for post CABG to exercise for post TAE, which deflect the movement of thigh in which the catheter was inserted, the lumbar region of the back and pelvis. Results: First, Low back pain scores in the experimental group were lower than the control group. Second, The first dose of analgesics in the experimental group was delayed compared to the control group. Third, There was no significant difference in bleeding complications between the experimental group control groups. Conclusion: The results suggest that the exercise program used in this study is effective for relief of low back pain in patients on absolute bed rest after TAE.

This paper describes the development of a rehabilitation robot that can provide wrist bending exercise to a severe stroke patient staying in a bed ward or at home. The developed rehabilitation robot has a three-axis force sensor which detects three directional force Fx, Fy, and Fz. The sensor measures a bending force (Fz) exerted on the wrist and the signal force (Fx and Fy) which can be used for the safety purpose. The robot was designed for severe stroke patients in bed, and the robot program was developed to perform a wrist bending rehabilitation exercise. In our tests including a nine-day experimental exercise, the developed force sensor-based robot operated effectively and safely.

The silk amino acid supplementation is unknown to affect the release of several hormones related to energy production and metabolism during prolonged exercise. This study examined the effects of silk amino acid supplementation on the level of blood amino acid, energy substrates and hormones level during prolonged treadmill exercise in college taekwondo player. A prolonged treadmill test was carried out 60 min at 65% of maximal heart rate on 8 athletics. Blood samples were obtained form antecubital vein of subjects at rest bed 30 minute before test, after exercise and rest 1 hour. The subjects were supplemented silk amino acid (6,390 mg/day) fur 4 week. The silk amino acid supplementation did not produce significant changes on the levels of blood lactate, ammonia, amino acid, glucose, triglyceride, total cholesterol, HDL, LDL, seratonin and leptin at rest bed 30 minute before test, after exercise and rest 30 minute. The silk amino acid 4 week supplementation did not affect the levels of blood amino acid, energy substrates and hormones during prolonged treadmill exercise.

This paper was designed to prevent intervertebral disc escape and treatment. we produced downsized lumbar traction bed at home and automated system depending on weight and muscle mass by using 3D print and Arduino to confirm the possibility of prototyping. Hence, we checked muscle mass 10 males in their 20s with different exercise conditions, and it shows that average muscle mass of group who exercised was 56.63kg, and non-exercise group was 50.8 kg. this is shows lumbar repetitive exercise can show the traction therapy effect can be seen traction therapy effect. In addition, we installed wooden doll substitute people with spring and test changing of length. Traction bed has the steps ranging from 1 to 4, in which the motor with torque and rpm, ranging from 4.7 to 5.5 kgf and from 4.5 to 5.3 rpm, respectively. The motor controlled with the voltage of Arduino was operated for the length of the spine to be stretched to 4-5 mm. As increasing the weight of the wooden doll by 10g, it was confirmed that the spring increased by 4-5 mm from the first step to the fourth step.

Background and Purpose: After the coronary angiography procedure, patients are required to remain on bed rest to reduce the risk of bleeding and hematoma formation at the puncture site. This prolonged bed rest in the supine position is difficult for many patients, who frequently complain of low back pain. The purpose of the study was to determine whether a specially designed exercise therapy and transcutaneous electrical nerve stimulation (TENS) had an effect on the alleviation of low back pain. Method: Sixty-two patients were assigned to one of three groups : specially designed exercise therapy plus TENS plus general nursing care (exercise group N=21), general nursing care plus TENS (TENS group, N=23) or general nursing care (control group, N=18). The exercise therapy consisted of five movements including stretching, pelvic tilting, knee to chest, modified situps and trunk rotation with minimizing the motion of the puncture site. The severity of low back pain was assessed by a visual analogue scale(VAS) every two hours. The use of analgesic and any development of bleeding or other complications were monitored as well. The level of serum ${\beta}$-endorphin was determined before and after the three interventions. Result: The pain score of the exercise group was significantly lowered compared to that of the other groups. There was no difference in the serum ${\beta}$-endorphin level among three groups. Analgesic were less frequently taken by the exercise group. However the incidence of bleeding complications was not significantly different among the three groups. Conclusion: Exercise therapy is more effective than general care or TENS in alleviating low back pain of the patients with coronary angiography.

The improving in physical activity of Disability elder is the most important and effective way of prevent and treatment. Especially, It improves ADL(Activities Daily of Living) by decreasing restrictive function and dependence. This study was researched on change by comparing before and after about ADL of Women elders who were instructed self rehabilitation exercise in bedside and have been take that. The whole subjects are 92 persons. Elders aged 65 to 69 are 32 persons. elders aged 70 to 74 are 22 persons 38 persons are over the age of 75. This study shows that the whole subjects have been improved ADL. especially, "Take a bath" in detail items of ADL comes to the most improvement rate. Next, "Sit to stand on the bed and transfer" comes to the second highest rate. According to findings upon the age group. "Take a bath" is also the highest improvement rate. Elders aged 60 to 65 show "Sit to stand on the bed and transfer" is the second highest rate of improvement" and elders aged 70 to 74 show that "control urine" is the second highest rate of improvement. and elders over the age of 75 shows that "sit to stand on the bed and transfer" is the second highest rate of improvement. This study have some problems on having possibilities of results because hospitalized persons have answered imperfect statement and being compare progressed for short term with rehabilitation exercise. so, There are some causes that is early to be generalized.
