The purpose of this study was to evaluate the factors influencing the ambulatory status in hemiplegia with intracerebral hemorrhage after rehabilitation. Thirty patients with stroke who was admitted in the Chosun University Hospital, between from January 1st' 1998 and December 31st' 1998, were included in this study. The following variables as a potential predictors for ambulation were evaluated at treatment of the stroke onset; 1) general characteristics including age and sex, and 2) clinical characteristics including frequency and onset time of the stroke, affected side, duration of the treatment, time interval between onset and rehabilitation, manual muscle test of paretic limb, sitting and standing balance, proprioception, perception, cognitive function. We compared and analyzed the these variables to the two type of ambulatory status at the time of the discharge by Modified Barthel Index, independent, dependent. The data were analyzed by student t-test, Fisher-exact test, Mann Whitney-U test, $X^{2}$-test, correlation analysis(spearman's). The results were as follows; 1. Were no significantly inflenced independent ambulatory status among general characteristics. 2. Frequency of the stroke and proprioception (p<0.05), muscle strength of the lower limb, cognitive function and standing balance (p<0.01), perception and sitting balance (p<0.001) were significantly inflenced independent ambulatory status among clinical characteristics. 3. Independent Variable correlated with the ambulatory status were muscle strength of the lower limb, proprioception and sitting balance (p<0.05), standing balance, frequency of the stroke, perception and cognitive function (p<0.01). Therefore the muscle strength of the lower limb, proprioception, sitting balance, standing balance, frequency of the stroke, perception, cognitive function were the most significant influencing factors of ambulatory status after rehabilitation.

The purpose of this study was to determine effects of the Ga-As (Gallium-Arsenide) Dens-Bio laser on mechanically injured sciatic nerves of rats. The improvement of the injured rat sciatic nerve was evaluated by measuring of nerve conduction velocity and amplitude of compound muscle action potential. The sciatic nerves of forty male Sprague-Dawley rats were compressed with hemostatic forceps for 30 seconds. The experimental group was divided into 4 subgroups according to the duration of treatment. Lower power infrared laser irradiation was done transcutaneously to the injured sciatic nerve area, 3 minutes daily to each of four treatment groups for 1, 3, 5, and 7 weeks, respectively. Compound muscle action potential and nerve conduction velocity of sciatic nerve were obtained before nerve injury and at 1, 3, 5, and 7 weeks after injury. There were significant difference of the nerve conduction velocity and amplitudes of compound muscle action potential between the treatment group and non-treatment group at 1, 3, and 5 weeks after laser treatment. However, there were no differences found between the electrophysiologic parameters that were measured after 7 weeks in two groups. There was significant correlation between the increment of compound muscle action potential and nerve conduction velocity after time course according to laser treatment. In conclusion, the low power laser treatment had improved the sciatic nerve function, and therefore these results may provide the basic data to clarify the neurological recovery and treatment after incomplete peripheral nerve injury. 저출력 적외선 레이저가 손상된 말초신경의 재생에 미치는 영향을 알아보기 위하여 흰쥐의 양측 좌골신경에 압궤손상을 준 뒤, 레이저 조사 기간에 따라 1, 3, 5 및 7주군으로 나누어 손상된 좌골신경의 신경전도속도와 진폭을 측정하여 신경재생의 정도를 관찰한 결과는 다음과 같았다. 좌골신경전도속도 검사에서 압궤손상 유발후에 손상전보다 유의하게 전도속도가 지연되었으나, 레이저를 조사한 실험측은 치료후 3주에 현저하게 신경전도 속도가 증가하였다. 좌골신경 진폭 검사에서 압궤손상 유발후에 손상전보다 유의하게 진폭이 감소하였으나, 레이저를 조사한 실험측은 치료후 3주에 복합근 활동전위의 진폭이 유의하게 증가하였다. 이상의 결과로 보아, 저출력 레이저 조사는 손상된 좌골신경의 기능회복에 있어, 주로 손상 초기의 회복속도에 영향을 주는 것으로 생각되는 바, 향후 말초신경 손상의 재활치료에 고려해야 할 것으로 생각된다.

Knee osteoarthritis is one of the most prevalent arthritis that weakens the muscles. This study focused on evaluating muscular functionality of knee osteoarthritis subjects. Muscular strengths of muscles around knee and hip joints of middle aged female subjects aged over 40 suffering from knee osteoarthritis were evaluated by isokinetic dynanometer. Also, relation between the observed muscle imbalance in knee and hip joints and visual analogue scale was investigated. Subjects performed 8 weeks exercise on weakened muscles particularly on knee extensors and hip abductors and had their isokinetic muscular functionalities analyzed again. After the 8 weeks exercise, subjects` thigh circumferences were increased, accompanied with muscular strength improvements and decrease in visual analogue scale. Hence we emphasize the importance of exercise for muscular strength enhancement of knee extensors and hip abductors, in rehabilitation programs for knee osteoarthritis.

Aphasia in adults occurs secondary to cortical or subcortical disease such as stroke to the language-dominant left hemisphere. Aphasia is an acquired communication disorder characterized by an impairment of language modalities, speaking, listening, reading and writing. Stroke is the most common cause of aphasia. It can be classified into specific syndromes according to the ability to produce, understand, repeat language, and fluency. There are several syndromes of aphasia such as Broca's aphasia, Wernicke's aphasia, conduction aphasia, global aphasia, transcortical motor aphasia, transcortical sensory aphasia, anomic aphasia and each is associated with a particular set of language capabilities and disabilities. Global aphasia is when both expressive and receptive problems are present. Treatment by speech therapist is based on a careful assessment of all communication modalities: speaking, listening, reading, and writing for restoration of speech and language abilities, and treatment was individualized. Common methods of speech therapy are auditory stimulation approach, melodic intonation therapy, and visual action therapy. The primary treatment for aphasia is speech therapy that focuses on relearning and practicing language skills and using alternative or supplementary communication methods. The purpose of speech therapy is to help the patient to fully utilize remaining skills and to learn compensatory means of communication. Patients’ families are very important in the rehabilitation process. In the recovery from aphasia the importance of an interested spouse, family or communication partner and environmental support. The importance of application of the specific methods and therapies for the rehabilitation of aphasic patients is pointed out.
