We developed a PC-based 8-channel electrical stimulation system for transcutaneous functional electrical stimulation (FES), and applied it to FES exercise and paraplegic walking. The PC program consists of four parts: a database, a stimulation pattern generator, a stimulus parameter converter, and an exercise program. The stimulation pattern can be arbitrarily generated and edited by using the mouse on the PC screen, and the resulting stimulus parameters arc extracted from the recruitment curves, and transmitted to the 8-channel stimulator through the serial port. The stimulator has nine microprocessors: one master and eight slaves, Each channel is controlled by the slave microprocessor, and is operated independently. Clinical application of the system to a paraplegic patient showed significant increase in the knee extensor torque, the fatigue resistance, and the leg circumference, The patient can now walk about 50 meters for more than 2 minutes.

Purpose: The purpose of this study was to determine the effectiveness of hand acupressure in relieving constipation among patients with paraplegia. Methods: Data were collected from a total of 52 participants with paraplegia from a spinal cord injury. Data were analyzed by chi-square test and t-test using SPSS/WIN 21.0. Results: The numbers of bowel movements per week increased in the experimental group who have received hand acupressure increased as compared with the control. Satisfaction with defecation of the experimental group improved as compared with the control. The level of constipation in the experimental group decreased compared to the control. Conclusion: We found that hand acupressure is effective in relieving constipation among patients with paraplegia from a spinal cord injury.

This paper Presents a 3-D design and a Vibration control of a new walking R.G.O.(Robotic Gait Orthosis) and would like to develop a simulation by this walking system. The vibration control and evaluation of the new knee joint mechanism on the biped walking R.G.O.(Robotic Gait Orthosis) was a very unique system and was to obtain by the 3-axis accelerometer with a low frequency vibration for the paraplegia It will be expect that the spinal cord injury patients are able to recover effectively by a biped walking R.G.O.. The new knee joint system of both legs were adopted with a good kinematic characteristics. It was designed attached a DC-srevo motor and controller, with a human wear type. It was able to accomodate itself to a environments of S.C.I. Patients. It will be expect that the spinal cord injury patients are able to recover effectively by a new walking R.G.O. system.

This research was designed to investigate how the exercise program affects paraplegic standing and walking employing functional electrical stimulation(FES). Emphasis was also given to fatigue of major lower extremity muscles induced by different types of electrical stimulation. We applied continuous and intermittent rectangular pulse trains to quadriceps of 10 normal subjects and 4 complete paraplegic patients. The frequencies were 20Hz and 80Hz, and the knee angle was fixed at 90$^{\circ}$and 150$^{\circ}$to investigate how muscle fatigue is related to muscle length. The knee extensor torque was measured and monitored. We have been training quadriceps and gastrocnemius of a male paraplegic patient by means of electrical stimulation for the past two year. FES standing was initiated when the knee extensors became strong enough to support the body weight, and then the patient started FES walking utilizing parallel bars and a walker. We used an 8-channel constant-voltage stimulator and surface electrodes. The experimental results indicated that paralyzed muscles fatigued rapidly around the optimal length contrary to normal muscles and confirmed that low frequency and intermittent stimulation delayed fatigue. Our exercise program increased muscle force by approximately 10 folds and decreased the fatigue index to half of the initial value. In addition, the exercise enabled the patient to voluntarily lift each leg up to 10cm, which was of great help to the swing phase of FES walking. Both muscle force and resistance to fatigue were significantly enhanced right after the exercise was applied every day instead of 6 days a week. Up to date, the patient can walk for more than two and half minutes at 10m/min while controlling the on/off time of the stimulator by pushing the toggle switch attached to the walker handle.

<보건세계> 원고 부탁을 받고 하나원에서 간호사로 12년 넘게 근무하면서 만났던 북한이탈주민들 중 간호했던 한 결핵환자와의 인연을 떠올리게 되었습니다. '지금 그녀는 어떻게 살고 있을까?' 그들 가운데 가장 기억에 남는 K에 관한 얘기를 기억 속에서 꺼내보려 합니다. 이 글은 북한사회의 경제적 어려움 때문에 결핵 진단을 받고도 약을 구할 수 없어 치료를 방치하다 결핵균이 뇌막염을 일으켜 하반신 마비라는 영원한 장애를 갖게 된 이야기입니다. 영화 갈이 멀기만 한 이야기가 바로 오늘 우리와 함께 사는 탈북민의 이야기이며, 우리가 그들과 함께 더불어 살아야하는 이유입니다.

This paper describes and discusses the employment of HMG pattern analysis to provide upper-motor-neuron paraplegics with patient-responsive control of FES ( functional electrical stimulation) for the purpose of walker-supported walking. The use of above-lesion EMG signals as a solution to the control problem is considered. The AR(autoregressive)parameters are identified by time-varying nonstationary Kalman filler algorithm using DSP chip and classified by fuzzy theory. The control and stimuli part of the below-lesion are based on micro-processor(8031). The designed stimulator is a 4-channel version. The experiments described above have only attempted to discriminate between standing function and sit-down function A further advantge of the this system Is applied for motor rehabilitation of social readaption of paralyzed humans.

Continuous epidural infusion, a combination of local anesthetic and opioid, have been widely administered for treatment of chronic cancer pain. A serious complications of epidural block is paraplegia which can also be caused by : direct spinal cord injury, epidural hematoma, epidural abscess, ischemic change, neurotoxicity, preexisting disease. Continuous epidural block for pain control of patient with cervical cancer was performed at $T_{12}/L_1$ interspace. A 4 cm catheter was inserted cephalad into the epidural space. After four months, back pain and motor weariless of lower extremities progressively developed. Spine CT showed bony destruction and soft mass-like lesion at $T_9$ & $T_{12}$ spine. We propose paraplegia was caused by spinal cord compression which resulted from vertebral metastasis of cervical cancer.
