Although canine facial nerve paralysis(FNP) occurs similarly in humans, there is no properly recognized therapy using Western medicine for idiopathic causes. To elucidate therapeutic measures by acupuncture(AP) on canine FNP, we examined the therapeutic effect of injection-AP on the artificially induced canine FNP. Twelve dogs on artificially induced canine FNP were divided into a control group(4 dogs), an experimental dexamethasone-treated group(dexamethasone group, 4 dogs) and an experimental bee venom-treated group(apitoxin group, 4 dogs). Saline (1 ml) was intramuscularly injected into the head muscle after the induction of FNP in the control group. On the other hand, injection-AP with dexamethasone was performed on such acupoints as LI04, LI20, ST02, ST07, TH17, SI18, GB03 and GB34, twice per week after induction of FNP in the dexamethasone group. In addition, injection-AP with $100{\mu}g$ of apitoxin was performed on the same acupoints as the dexamethasone group twice per week after the induction of FNP in the apitoxin group, respectively. The changes of the clinical symptoms of FNP with each treatment during the experimental period were recorded by using clinical scores, respectively. The changes of serum creatine kinase(CK) activities along with each treatment were determined using an autoanalyzer. The significant differences of clinical scores were detected on day 14(p<0.05) in the apitoxin and dexamethasone groups, compared with those in the control group, respectively. However, significant difference was not detected between the apitoxin and dexamethasone groups. Significant differences of serum CK activities were detected on day 7(p<0.05) and day 14(p<0.05) in the dexamethasone and apitoxin groups, compared with those in the control group, respectively. However, significant difference was not detected between the dexamethasone and apitoxin groups. In condition, injection-APs with apitoxin and dexamethasone were all effective for treatment of canine FNP and the therapeutic effect by injection-AP with apitoxin was similar to that of injection-AP with dexamethasone.

Purpose: The purpose of this study was to investigate the effects of biofeedback exercise training on muscle activity and activities of daily livings (ADL) in hemiplegic patients. An experimental group consisting of 17 people, was given biofeedback exercise training for 30- 60 minutes per week for 5 weeks, while a control group consisting of 18 people, was given normal exercise with quasi-experimental design. Result: The results of the study show that biofeedback exercise is effective for improving muscle activity in hemiplegic patients, especially in the hemiplegic limbs. However, this study found no significant differences in ADL and IADL between the experimental and the control groups. It implies that ADL and IADL may not be improved for a short period of time, such as 5 weeks, for people with more than five years of hemiplegia. The study suggests that the effect of biofeedback exercise on ADL and IADL should be determined in hemiplegic patients in acute stage.

Cerebral Palsy is a genetic term referring to abnormalities of motor control caused by damage to a child's brain early in the course of development. Due to the impairment of balanced perioral muscle development, the prevalence of malocclusions in patients with cerebral palsy such as maxillary protrusion is high. But most clinicians may feel uncomfortable to treatment of these problems. Here a case report about mitigation of maxillary anterior teeth protruded in patient with cerebral palsy. 8y 4m old boy who have cerebral palsy visited our dental hospital. He showed severely protrusive maxillary anterior teeth with mouth breathing and could not close his mouth. He and his mother wanted to improve dental and facial esthetic problem. Specially designed or modified intraoral fixed appliance and rubber elastic chain was used in the therapy. Treatment carried out for 8 months and we could observe maxillary incisor angle was improved and mouth breathing habit was stopped. In conclusion, modified fixed appliance therapy for the patients with cerebral palsy might be useful. Continuous rehabilitation training of lips should be followed after treatment to correct imbalance of muscle tone.

In this study, we investigated the effects of stretching and movement with mobilization in lunge position on the muscle activity of the lower limb and limited of stability in chronic stroke patients with hemiplegia. Sixteen subjects were randomly selected and classified into the experimental and control groups. The experimental group performed self stretching exercises in the lunge position, and in the control group performed movement with mobilization in the lunge position. The interventions were conducted for 20 min, 5 times a week for 8 weeks. Statistical analyses were performed using repeated ANOVA. The analysis results showed no statistically significant between-group differences with respect to the muscle activity(%MVIC;maximum voluntary isometric contraction) of lower limb and limited of stability(LOS)(p>.05). However, statistically significant within-group differences were observed in the maximum voluntary isometric contraction and limited of stability for both the groups (p<.05). Therefore, self stretching in the lunge position is considered to have positive influences on the muscle strength and balance in stroke patients with hemiplegia.

Purpose: We wanted to evalulate the clinical results of pectoris major tendon transfer for a neglected winged scapula that was caused by paralysis of the serratus anterior due to injury to the long thoracic nerve. Materials and Methods: A patient had neglected winged scapula that followed an arthroscopic operation for multi-directional instability of the shoulder joint, which was caused by traumatic dislocation. The patient was treated with pectoralis major tendon transfer using the modified Eden-Lange procedure. The range of a motion was improved from forward flexion $90^{\circ}$ and external rotation $70^{\circ}$ to $170^{\circ}$ and $150^{\circ}$ respectively. Results and Conclusion: There were no complications or recurrence and the patient's psychological satisfaction was also high. If the shoulder girdle muscles are intact, except for the serratus anterior, then pectoralis tendon transfer is a satisfactory method that can provide normal scapulo-thoracic motion.

Purpose : Bell's palsy is defined as an idiopathic facial nerve paralysis of sudden onset. In spite of intensive clinical and experimental investigation, there is still uncertainty in the incidence, etiology, and preferred mode of treatment in children. The objective of this study was to analyze clinical outcome and prognosis of children with Bell' palsy. Methods : We analyzed 61 cases of Bell's palsy diagnosed at the Department of Wonkwang University Hospital from January 1998 to July 2006. The inclusion criteria were any children with acute isolated unilateral lower motor neuron type of facial nerve palsy. The clinical findings and investigations were reviewed including age, sex, affected site, seasonal incidence and result of steroid treatment. Chi-square and Fisher's exact test was used to compare clinical outcome between duration of complete recovery and age. Results : There was no difference in incidence according to sex or age. Incidence was higher in summer and winter. There was no difference in complete recovery rate and duration between steroid treated group and control group. In the group of children younger than 6 years, duration of complete recovery was shorter than older children. Conclusion : We found increasing the incidence of Bell's palsy in summer and winter. Children younger than 6 years had shorter duration in complete recovery.

Electromyogram (EMC) signal generated by voluntary contraction of muscles is often used in a rehabilitation devices such as an upper limb prosthesis because of its distinct output characteristics compared to other bio-signals. This paper proposes an EMG-based human-computer interface (HCI) for the control of the above-elbow prosthesis or the wheelchair. To control such rehabilitation devices, user generates four commands by combining voluntary contraction of two different muscles such as levator scapulae muscles and flexor-extensor carpi ulnaris muscles. The muscle contraction is detected by comparing the mean absolute value of the EMG signal with a preset threshold value. However. since the time difference in muscle firing can occur when the patient tries simultaneous co-contraction of two muscles, it is difficult to determine whether the patient's intention is co-contraction. Hence, the use of the comparison method using a single threshold value is not feasible for recognizing such co-contraction motion. Here, we propose a novel method using double threshold values composed of a primary threshold and an auxiliary threshold. Using the double threshold method, the co-contraction state is easily detected, and diverse interface commands can be used for the EMG-based HCI. The experimental results with real-time EMG processing showed that the double threshold method is feasible for the EMG-based HCI to control the myoelectric prosthetic hand and the powered wheelchair.

This paper proposes a small-scale rehabilitation system that allows stroke patients to perform daily rehabilitation training in a virtual home. Stroke patients have limited activities of daily living due to paralysis, and there are many rehabilitation exercises for them to reproduce activities that take place in the house, such as turning lights on and off, door opening and closing, gas valve locking. In this paper, we have implemented a virtual home with the above mentioned daily rehabilitation training elements, by using virtual reality technology. We use Leap Motion, a hand motion recognition device, for rehabilitation of hands and fingers. It is expected that stroke patients can rehabilitate small muscles without having to visit the clinic with uncomfortable body, and will be able to get interesting rehabilitation training by avoiding monotony of existing rehabilitation tools.
