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.

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.

Objectives: This study investigated the change of foot rotation angle of gait analysis parameters according to gait improvement in post-stroke hemiplegic patients. Methods: We measured the foot rotation angle of eight post-stroke hemiplegic patients at the time of dependent and independent gait. Results: The foot rotation angle of the paralyzed side reduced closer to normal average according to gait improvement, but the non-paralyzed side not significantly. Conclusions: Improvement of foot rotation is an important thing for independent gait of post-stroke hemiplegic patients so this treatment seems worthy of being considered in clinical trials.

To evaluate of the ultrasonographic changes in hemiplegic and unaffected knee joints of hemiplegic ambulators with recent onset stroke. Twenty patients (40 knees) with prevalence duration of 14-39 weeks (mean 24.70 weeks) after a stroke insult were included. All participants were walking independently without leg dragging, had no previous knee injury. There were significant differences in intercondylar cartilage thickness and pes anserinous tendinopathy (PAT) between hemiplegic and unaffected knees (p<0.05). There were no differences in cartilage thickness of medial condyle and lateral condyle, patellar tendinitis/bursitis, suprapatellar effusion, synovitis, joint space narrowing, and Baker's cyst of ultrasonographic findings and x-ray findings in hemiplegic knee compared to the control except PAT (p<0.05). In hemiplegic knee, medial or lateral condylar cartilage thickness was significantly correlated with body weight, intercondylar cartilage thickness, and PAT (p<0.05). PAT was significantly correlated with Brunnnstrom stage and condylar cartilage thickness (p<0.05). Knee pain was significantly correlated with lateral condylar cartilage thickness (p<0.1). The hemiplegic knee had more ultrasonographic abnormalities including PAT and more cartilage thickness preservation in patient with recent onset stroke. Intraarticular sonographic findings including cartilage thickness was significantly correlated with extraarticular findings including PAT and a symptom of knee pain.

For many stroke patients undergoing rehabilitation therapy, there is a need for indicator for evaluating the body function in paretic and non-paretic regions of stroke patients quantitatively. In this paper, the function of muscles and cells in paretic and non-paretic regions of severe and mild hemiplegic stroke patients was evaluated using multi-channel bioelectrical impedance spectroscopy. The paretic and non-paretic regions of severe and mild stroke patients were quantitatively assessed by using bioelectrical impedance parameters such as prediction marker (PM), phase angle (${\theta}$), characteristic frequency ($f_c$), and bioelectrical impedance vector analysis (BIVA). The mean values of impedance vector were significantly discriminated in all comparisons (severe-paretic, severe-non-paretic, mild-paretic, and mild-non-paretic). The bioelectrical impedance parameters were proved to be a very valuable tool for quantitatively evaluating the paretic and non-paretic regions of hemiplegic stroke 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.
