Purpose: This study investigated the change in plantar fascia thickness in hemiplegic and non-hemiplegic feet in stroke patients using an ultrasonographic evaluation. Methods: Sixteen hemiplegic and non-hemiplegic feet from 16 hemiplegic patients (patient group) and 16 feet from 8 healthy subjects (control group) were evaluated by ultrasonography. The sagittal sonograms were obtained in the prone position, and the plantar fascia thickness was measured at its insertion into the calcaneus. Results: The mean plantar fascia thickness was measured to be $4.5\pm0.8$mm in hemiplegic feet of the patient group, $3.4\pm1.0$mm for the contralateral non-hemiplegic feet and $2.8\pm0.3$mm for the control group. There was a statistically significant difference in plantar fascia between the hemiplegic feet and contralateral non-hemiplegic feet as well as between the contralateral non-hemiplegic feet and control group (p<0.01 and p<0.05, respectively). The plantar fascia thickness according to the Brunnstrom stage and modified Ashworth scale was increased significantly in the hemiplegic feet (p<0.01). Conclusion: These results show that the plantar fascia is overloaded in the hemiplegic and non-hemiplegic feet of stroke patients. A therapeutic approach should be considered for these patients.

Objective: This study analyzes the effect of angle conditions of rehabilitation equipment used for supporting hemiplegic patients on their rehabilitation training for standing action. The study was performed by adjusting the rear angle of seat inclination through a motion analysis. Background: Owing to a loss of muscle rigidity and degradation of muscle control ability, hemiplegic stroke patients suffer from asymmetrical posture, abnormal body balance, and degraded balance abilities due to poor weight-shifting capacity. The ability to shift and maintain one's weight is extremely essential for mobility, which plays an important role in our daily life. Thus, to improve patients' ability to maintain weight evenly and move normally, they need to undergo orthostatic and ambulatory training. Method: Using a motion analysis system, knee movements on both hemiplegic side and non-hemiplegic side were measured and analyzed in five angles ($0^{\circ}$, $10^{\circ}$, $30^{\circ}$, $50^{\circ}$, $70^{\circ}$) while supported by the sit-to-stand rehabilitation equipment. Results: The knee movements on both sides increased as the angle increased in angle support interval to support a hemiplegic patient's standing up position. In standing up interval, a hemiplegic patient's knee movement deviations on both sides decreased, and the movement differences between hemiplegic and non-hemiplegic legs also decreased as the angle increased. Conclusion: The results of this study showed that the rehabilitation effectiveness increases as the angle increases, leading to a balanced standing posture through the decrease of movement difference between hemiplegic and non-hemiplegic sides and an improved standing up ability through the increase of knee movement on both sides. However, angles higher than $50^{\circ}$ didn't provide a significant effect. Therefore, a support angle under $50^{\circ}$ was proposed in this study. Application: The results of this study are expected to be applicable to the design of sit-to-stand support equipment to improve the effectiveness of the rehabilitation process of hemiplegic patients.

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.

Stroke patients have increased with the overall aging of our population, 60 years and older. Recently the number of stroke patients has been on the increase even among younger people in their thirties. The family support is frequently mentioned as a major variable which plays an important role in helping the patients adapt themselves to their hemiplegic situations. The purpose of the study was to examine between family support and activities of daily living(ADLs)abilities for the hemiplegic patients, and to provide the basic data to help the patients carry out their ADLs on their own. The sample for the study included 106 hemiplegic patients and their family members. The data were collected using a focused, structured interviews. The major findings of the study were as follows: 1. The hemiplegic patients perceived that their family supports were very high(Mean, 49.00). 2. The degree of family support was significantly higher in female. high economic status, and non-use of brace patients than in male, poor economic status, use of brace patients. 3. The ADL abilities of the hemiplegic patients were significantly higher in ambulatory, younger, and longer-period-of-illness patients and patients who used a cane as a assistive device. 4. The family support for the hemiplegic patients showed a statistically significant Cor relationship with their performance of ADL(r=.30809. p=0.0013). 5. The performance of ADL for the ambulatory patients were mainly affected by the degree of family support, the period of the hemiplegic illness, the use of brace, informal care giving, and the age. These variables explained 50% of variance. 6. The length of illness was a statistically significant affecting variable for ADL performance in OPD and assistive device in IPD. In conclusion, the higher the hemiplegic patients perceived the degree of family support, the better they performed ADL. We should develop nursing methods which enhance the family support for the hemiplegic patients in order to increase their performance of ADL.

The study aims to distinguish hemiplegic gait and normal gait using simple wearable device and classification algorithm. Thus, we developed a wearable system equipped three axis accelerometer and three axis gyroscope. The developed wearable system was verified by clinical experiment. In experiment, twenty one normal subjects and twenty one patients undergoing stroke treatment were participated. Based on the measured inertial signal, a random forest algorithm was used to classify hemiplegic gait. Four-fold cross validation was applied to ensure the reliability of the results. To select optimal attributes, we applied the forward search algorithm with 10 times of repetition, then selected five most frequently attributes were chosen as a final attribute. The results of this study showed that 95.2% of accuracy in hemiplegic gait and normal gait classification and 77.4% of accuracy in hemiplegic-side and normal gait classification.

Hemiplegic migraine is a typical symptom of general migraine. With this disorder, patients at any age can have a series of unilateral paralysis that would outlast a normal headache. It can be classified into three types, such as familiar hemiplegic migraine, sporadic hemiplegic migraine and unclassifiable hemiplegic migraine. Although it is known that normal hemiplegic migraine is associated with the gene on chromosome 19, the accurate cause and effective therapeutics have not been demonstrated yet. When a patient, subjected to this study complained unilateral hemiparesis and sensory disturbance with severe migraine and dysarthria, we thought that the direct cause of this symptoms was the stress. Therefore, we approached this disorder by focusing on the psychological aspect and finally gained a good result with Chilbok-yeum which releases the psychological irritation, so we report it for the better treatment.

The purpose of this study was to suppose basis data the influence of different chair type and pelvic control on quadriceps muscle activity and strength during knee joint extension isometric exercise in hemiplegic patients. This research were investigated in ten healthy adults and tens hemipelgic patients. Surface electromyography (EMG) and Biodex system were used to collect kinematic data and muscle activity, respectively. Independent t-test, paired t-test and one-way repeated ANOVA were used to determine a statistical significance. The results showed as follows: (1) Posterior pelvic angles in healthy group and hemiplegic group were significantly different on isokinetic equipment (p<.05). (2) Different chair type and pelvic control on quadriceps muscle activity and strength were significantly different in hemiplegic patients (p<.05). From the result of this research, posterior pelvic angle control during knee joint extension isometric exercise in hemiplegic patients on isokinetic equipment is necessary to increase quadriceps muscle strength in hemiplegic patients.
