본 연구는 고지방식이로 인한 비만으로 불균형된 지질구성과 산화적 손상이 신경세포형성과 초기발현단백질에 미치는 생물학적 영향을 알아보고, 규칙적인 운동의 효과를 알아보기 위하여 실시하였다. 실험동물은 4주령 SD rat 수컷 30마리를 1주간의 적응기간을 둔 뒤, 15주간 고지방식이를 통해 비만으로 유도하였으며, high fat diet sedentary (HDS, n=15)와 high fat diet and training (HDT, n=15)으로 분류하여 연구하였다. 운동강도는 1~4주는 저강도, 5~8주는 중강도로 주5회 실시하였다. 8주 트레이닝 후 혈청지질, 8-OHdG, MDA, neurotrophic factor, 그리고 IEG를 분석하였다. 그 결과 TC와 TG에서 HDS와 HDT 사이 유의한 차이가 나타났다(p<0.05). 8-OHdG에서 HDT는 트레드밀 트레이닝 후에 HDS보다 낮게 나타났다(p<0.05). 해마에서 c-jun, BDNF 그리고 간에서 MDA의 단백질 발현은 HDT가 트레드밀 트레이닝 후 HDS보다 높게 나타났다(p<0.05). 결론적으로 8주간 트레드밀 훈련은 고지방식이 비만 유도 쥐의 혈청지질 성분의 불균형을 개선시키고, 조직과 혈청의 산화적 손상과 DNA 손상을 완화시켜 주어, 비만으로 인한 합병증 예방에 도움을 줄 수 있을 것으로 사료된다. 또한 NT의 발현을 증가시킴으로써 손상된 뇌기능과 신경세포의 생성 기전 활동에 긍정적 영향을 나타냄으로써 공간적 학습기능의 향상을 가져온 것으로 판단된다.

The tenn 'Brain plasticity' has been identified that our central nervous system is continuously being adapted and modulated according to environmental needs and demands, and has been used to encompass the multifarious mechanisms related to learning, development, and recovery from damage to the nervous system. The purpose of this study was to demonstrate cortical reorganization in a 26-year-old right-handed hemiparetic patient with traumatic primary motor cortex (M1) injury, using functional MRI (fMRI). The unaffected (left) primary sensori-motor cortex centered on the precentral knob was activated during unaffected (right) hand movements. However, the medial area of the injured M1 was activated during affected (left) hand movements. It seems that the motor function of the affected hand in this patient was reorganized into the medial area of the injured precentral knob. These investigations provide a great useful information and clinical evidences with the specialized clinician in stroke physical therapy about patient's prognosis and therapeutic guidelines.

Purpose: New therapeutic approaches have emerged to improve gait ability in patients with brain damage, such as action observation learning (AOT), auditory cueing, motor imagery etc. We attempted to investigate the effects of AOT with auditory cueing (AOTAC) on gait function in patients with stroke. Methods: The eighteen stroke patients with a unilateral hemiparesis were randomly divided into three groups; the AOTAC, AOT, and control groups. The AOTAC group (n=8) received training via observing a video that showed normal gait with sound of footsteps as an auditory cue; the AOT group (n=6) receive action observation without auditory stimulation; the control group (n=5) observed the landscape video image. Intervention time of three groups was 30 minutes per day, five times a week, for four weeks. Gait parameters, such as cadence, velocity, stride length, stance phase, and swing phase were collected in all patients before and after each training session. Results: Significant differences were observed among the three groups with respect to the parameters, such as cadence, velocity, stride length, and stance/swing phase. Post-hoc analysis indicated that the AOTAC group had a greater significant change in all of parameters, compared with the AOT and control groups. Conclusion: Our findings suggest that AOTAC may be an effective therapeutic approach to improve gait symmetry and function in patients with stroke. We believe that this effect is attributable to the change of cortical excitability on motor related to cortical areas.

Background: Cervical headache (CGH) is a common condition that causes serious damage. Mulligan described a sustained natural apophyseal glides (SNAGs) as a manual therapy approach to treat this dysfunction. Although there have been several case studies to evaluate the effectiveness of SNAG, the efficacy of SNAG for cervical headaches is still controversial. Therefore, this study examined the effects of Mulligan's SNAG technique on cervical headache and pain intensity to present basic clinical data. Methods: Thirty-two subjects participated in this study, 16 each in the experimental and control groups. The experimental group applied Mulligan's SNAGs technique and the control group applied the placebo SNAGs technique. Results: Significant differences (p<.05) in the changes in pain, neck disability index (NDI) and Hamilton rating scale for depression (HRSD) were observed between the two groups. Conclusion: The application of Mulligan's SNAG technique to patients with cervical headaches effectively reduced headache, depression, and neck dysfunction. Based on this study, Mulligan's SNAGs technique can be used as an objective research method for additional studies targeting cervical headache patients in the future.

In most of the medical literature that discusses the common problem of movement in patients with cerebral lesions. This critical problem is ascribed to a mechanism involving uninhibited neural activity. The goals of neurological physical therapy are focus on reduce of muscle hypertonicity, facilitates muscle activities, and improve of performance in living environment. A variety of studies suggest that spasticity is a distinct problem and separate from the muscle weakness. It has become increasingly recognized that the major functional deficits following brain damage are largely due to negative features such as muscle weakness and loss of performance rather than spasticity. Adequate recruitment of prime mover, not release was able to carry out the movement tasks well. The strengthening exercise of spastic limbs on changes in muscle properties and performance skill, the repeated motor practice has been identified as crucial for motor recovery. This article support the concept that strengthening is an appropriate intervention to improve the quality of physical function in patients with central nervous system lesions. Further studies and therapeutic approaches should be efforts at improving motor neuron recruitment in agonist rather than reducing activity in antagonists while retraining muscle strengthening.

Purpose: In chronic stroke patients, muscle tone and stiffness increase due to ankle spasticity. Electrotherapy may control the spasticity of patients with central nerve system damage via neurophysiological mechanisms. Therefore, this study was conducted to determine the immediate effects of interferential current therapy on gastrocnemius (GCM) muscle. Methods: This study was a one-group pretest-posttest design and 20 stroke patients participated. The experimental group underwent interferential current therapy for GCM for 30 minutes. Muscle tone (MT) and stiffness were assessed using MYOTONE(R) PRO. After 30 minutes of interferential current therapy, MT and stiffness of the affected side and unaffected side by GCM were measured. Results: After interferential current therapy, the medial GCM MT (Hz) was significantly reduced in stroke patients. There was a significant difference in MT between affected GCM muscles and unaffected side medial GCM muscles before intervention, but there was no significant difference after interferential current therapy. Conclusion: This study demonstrated that interferential current therapy had a positive effect, producing an immediate decrease in the medial GCM muscles tone of stroke patients. However, this study employed a one-group pretest-posttest design. Future studies will show differences in muscle tone compared to a control group or other electrical stimulation treatments.

우리 법원은 의료과오소송에서 진료상 주의의무 위반의 경우 신체적 법익침해에 따른 재산적·비재산적 손해배상을 인정하고, 설명의무 위반의 경우 신체적 법익침해와 상관없이 자기결정권 침해에 따른 위자료 배상을 인정한다. 이러한 판례의 태도에 대하여 설명의무 위반에 따른 위자료 배상이 진료과오의 책임요건을 회피하는 수단으로 활용되고 있다는 비판이 있다. 이들은 결과적으로 신체침해가 아니라 선택기회 상실에 대해 위자료 배상을 인정하는 우리 판례를 신체침해에 대한 배상으로 일원화할 것을 주장한다. 이에 본 논문에서는 판례가 신체적 법익침해론을 따르는 독일과 우리의 의료과오소송의 차이를 검토하고, 독일에서의 설명의무 위반에 대한 논의를 소개하였다. 그리하여 우리와 독일의 인격적 법익침해론과 신체적 법익침해론, 그리고 설명의무 위반에 따른 손해배상 논의의 차이를 확인하였다. 이를 바탕으로 우리의 판례법리 및 인격적 법익침해론의 입장에서 설명의무 위반에 따른 손해배상책임의 주요쟁점을 검토하였다. 의료행위는 의학적 적응성이 인정되는 한 위법한 신체침습이 아니다. 의료행위에 대한 동의 역시 의료행위의 위법성을 조각시키기 위한 것이 아니다. 의료행위에 대한 환자의 동의는 자기결정권의 실행이고, 환자의 자기결정권은 의사의 설명을 통해 구체화된다. 의사가 설명의무를 위반한 경우, 불설명 혹은 설명부족은 그 자체로 부작위에 위한 위법행위를 구성한다. 그로 인하여 침해되는 법익은 자기결정권이다. 환자는 생명·신체에 대한 이익으로 연결되지 않는 때에도 신체에 대한 주체로 자신의 신체에 행해질 행위에 대해 알고, 스스로 결정할 수 있는 권리가 있다. 이러한 권리가 침해되어 선택의 기회가 상실되었다면, 그 자체로 비재산적 손해상태가 인정되어 위자료를 배상하여야 한다. 따라서 의료행위에 악결과가 없어도, 성공한 의료행위였다고 하더라도, 의사의 설명의무 위반으로 환자의 자기결정권이 침해되었다면 위자료 배상은 인정된다. 자기결정권 침해에 따른 위자료 배상에 의료행위로 인한 악결과는 요구되지 않는다. 한편 설명의무 위반의 경우에도 신체손해에 대한 배상이 부정되는 것은 아니다. 설명의무 위반으로 침해된 법익을 자기결정권이고, 선택기회상실이 통상손해로 인정된다. 그러나 자기결정권 침해로 선택기회가 상실되었고, 의사가 설명하여 환자가 선택기회를 잃지 않았다면 다른 선택을 했을 것임이 분명하고, 다른 선택을 했다면 악결과를 피할 수 있었음을 증명하면 악결과에 대해서도 배상을 받을 수 있다. 다만 이때 신체손해는 자기결정권 침해에 따른 특별손해로 의사의 예견가능성이 문제되는 것이기 때문에 의사가 예견할 수 없었던 불가항력적 손해는 배상의 대상이 되지 않는다.

This study was designed to investigate the effects of treadmill exercise of low-intensity and moderate- intensity on the functional recovery and histological change in spinal cord injury (SCI) rats. SCI was induced by the spinal cord impactor dropped after laminectomy. Experimental groups were divided into the Group I (normal control), Group II (non-treatment after SCI induction), Group III (low-intensity treadmill exercise after SCI induction), Group IV (moderate-intensity treadmill exercise after SCI induction). After operation, rats were tested at modified Tarlov scale at 2 days with divided into 4 groups, and motor behavior test (BBB locomotor rating scale, Grid walk test) was examined at 3, 7, 14, and 21 days. For the observation of damage change and size of the organized surface in spinal cord, histopathological studies were performed at 21 days by H & E, and BDNF(brain-derived neutrophic factor) & Trk-b immunohistochemistry studies were performed at 1, 3, 7, 14, 21 days. According to the results, treadmill exercise can play a role in facilitating recovery of locomotion following spinal cord injury. Specially, moderate-intensity treadmill exercise after SCI induction was most improvement in functional recovery and histological change.
