The Purpose of this study was to determine the clinical effectiveness of mirror therapy for stroke. Moreover, this paper was designed to summarize clarified information of neurological plasticity by mirror therapy to finally define the neurological mechanism. Mirror therapy improves the stroke patients' hand and arm motor function. It also has a positive influence on recovering performance of activities of daily living and relieving pain. However, it is not evident that mirror therapy restores visual neglect. There are various ways of recovering stroke. Fundamentally, all the theories are on a bases of restoration of premotor area. Premotor area which is associated with motor control increases the activation of primary motor area and finally improves patients' motor function. If primary motor area is completely damaged, premotor area and supplementary motor substitute for primary motor area. In summary of literature survey, there are not enough evidence to verify the effectiveness and neurological mechanism of mirror therapy. In future, more researches should be conducted to verify the neurological recovery through mirror therapy. Then, mirror therapy will be acknowledged as a clinically effective treatment.

Central cord syndrome (CCS) is the most common incomplete spinal cord injury (SCI) syndrome, occured by cervical hyperextension injury. It is characterized by disproportionately greater motor impairment in the upper extremities compared to the lower extremities, bladder dysfunction, and variable degrees of sensory loss below the level of injury. Recently 36 year-old male was admitted with upper motor neuron weakness, sensory loss in the upper extremities and stiff neck. We report the improvement of his symptoms through both western medical treatment and oriental medical treatment.

Background : Changes in firing pattern and in the recruitment order of single motor unit(MU) have been claimed to be characteristic of central motor lesions, and a reduced firing rate was found in upper motor neuron lesions. But these findings have been rarely studied before in Korea, so we studied initial MU recruitment pattern in stroke patients with hemiparesis. Methods : We studied six patients(3 men and 3 women) whose mean age was $60.6{\pm}7.4$ years. A mean $20.6{\pm}16.2$ months had elapsed since the stroke. To compare the initial MU activation patterns in proximal and distal segments of paretic limb with their contalateral unaffected counterparts, we studied the onset and recruitment intervals in biceps brachii(BB) and first dorsal interossei(FDI) muscles in paretic and healthy arms. In a single muscle we examined from 5 to 10 individual MUs. And in a single motor unit, both the onset interval and the recruitment interval was examined. Results : The mean onset interval in paretic limb was significantly(p<0.05) longer than unaffected limb at proximal and distal location: BB $118.5{\pm}17.8$ msec vs $96.1{\pm}8.3$ msec(n=58); FDI $125.8{\pm}16.7$ msec vs $101.5{\pm}17.2$ msec(n=38). The mean recruitment interval in paretic limb was also significantly(p<0.05) longer than unaffected limb: BB $87.7{\pm}14.9$ msec vs $73.4{\pm}11.5$ msec(n=53); FDI $96.3{\pm}16.4$ msec vs $87.7{\pm}14.1$ msec(n=38). Conclusion : The first recruited MU had a lower baseline firing rate and the second recruited motor unit potential appeared earlier in paretic than in healthy muscles. And these findings may explain one of the reasons for paresis in patients with stroke.

The usages of botulinum toxin were most commonly for the treatment of spasmodic dysphonia in the otolaryngology field. It has been not only widely used in otolaryngology-Head Neck surgery but also plastic surgery, ophthalmology, rehabilitation medicine, and orthopedics. Now botulinum toxin is used such as blepharospasm (excessive blinking), strabismus, cosmetic, muscle spasms, upper motor neuron syndrome, severe primary axillary hyperhidrosis (excessive sweating), cervical dystonia (spasmodic torticollis), chronic migraine, bruxism, and achalasia. The indication of this drug still gradually expanding with the times. In this articles, the author will demontrate how to use the botulinum toxin for treating cricopharyngeal spasm, arytenoid dislocation, sialocele, Frey syndrome, contact granuloma, bilateral vocal fold paralysis, and mutaional falsetto instead of conventional surgical treatment.

Flail arm syndrome (FAS), known as one of the atypical amyotrophic lateral sclerosis (ALS) variants, has a similar clinical course and pathologic findings as ALS. Therefore it is difficult to differentiate between ALS and FAS at a glance. There are few reports involving individual analysis of FAS patients to date. The findings of polysomnography (PSG) in patient with FAS are not well known. We report a male FAS patient with review of literatures and several issues related to the diagnostic process.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with numerous causes that include genetic factors. Efforts to reveal the genetics of ALS have identified several candidate genes that are associated with familial and sporadic ALS. Here we report a Korean ALS patient who showed prominent upper motor-neuron-related symptoms with marked brain atrophy and neuropsychological deficits. The findings were highly suggestive of ALS in a patient with a likely pathogenic FIG4 variant.

A castrated male, 9-year-old Yorkshire terrier was presented with a depression and bilateral hind limbs lameness. On physical examinations, upper motor neuron signs and stiffness of the hind limbs, back pain and progressive paresis were identified. Marked periosteal new bone formations and lysis include the first lumbar vertebra to the sacrum, bilateral iliums acetabulums and bilateral femoral heads were observed in survey radiographs. After death with septicemia suspected, renal infarction and the 5th vertebral osteomyelitis include pelvic periostitis were diagnosed in histological examination.

Man-in-the-barrel syndrome (MIBS) is a clinical syndrome of bilateral upper limb weakness with normal lower extremity function. It can be caused by various neurological conditions such as bilateral cerebral hypoperfusion, syringomyelia, motor neuron disease, or cervical myelopathies. We report a patient with MIBS after cervical spinal cord ischemia. It is postulated to be caused by ischemic insults of anterior spinal artery from repeated and prolonged neck extension.

Benign monomelic amyotrophy (BMA) is a benign motor neuron disease in which amyotrophic change is confined to either the upper or the lower extremities. Numerous cases of BMA have been reported from Japan and India. However, only a few cases have been reported from other regions, including South Korea. Here we report a rare case of late-onset BMA in Korean male using conventional diagnostic approach with magnetic resonance imaging and electromyography. The patient received ten sessions of manual therapy, which focused on strengthening of the left ankle. At two-month follow up, weakness was still isolated to the patient's left ankle. There were no signs of disease progression.

This paper describes and discusses the employment of EMG 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 Kalman filter algorithm using DSP chip and classified by fuzzy theory. The control and stimuli part of the below-lesion are based on microprocessor(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 advantage of the this system is applied for motor rehabilitation of social readaption of paralyzed humans.
