Purpose: This study examined the effect of EMG-stim related to the functional recovery of the upper extremity in chronic stroke patients with an intensive massed practice protocol. Methods: The subjects were assigned randomly to either the EMG-stim group (n=10) or sham treatment group (n=10). Both groups received conventional physical therapy, occupational therapy and FES, five times per week over a four week period. In the EMG-stim group, EMG-stim was applied to the hemiplegic wrist and finger extensors for 2 sessions for 30 minutes per day, 5 times per week over a 4 week period. As the pre- and the post-test, the following four motor tests were assessed as the function of the upper extremity clinical functional test: extensor digitorum strength test, Box and Block test, Fugl-Mayer Assessment, and Jebson-Taylor Hand Function Test. Results: In the Box and Block test and Fugl-Mayer Assessment, there were statistically significant differences between both groups as well as between pre- and post-test. The extensor digitorum and wrist extensor strength were similar in both groups. In the Jebson-Taylor Hand Function Test, there was a significant difference in simulated page turning but not in the other subtests. Conclusion: Intensive massed practice with EMG-stim intervention applied to the hemiplegic upper extremity is an effective therapeutic method for chronic stroke patients. However, a variety of intervention methods designed for stroke patients in clinical settings are needed.

Objective : There have been recent reports that mesenchymal stromal cells that are harvested from adipose tissue are able to differentiate into neurons. In the present study, we administered adipose tissue derived stem cells in rats with cerebral infarction in order to determine whether those stem cells could enhance the recovery of motor function. Methods : Cerebral infarction was induced by intraluminal occlusion of middle cerebral artery in rats. The adipose tissue-derived mesenchymal stem cells were harvested from inguinal fat pad and proliferated for 2 weeks in DMEM media. Approximately $1{\times}10^6$ cells were injected intravenously or into subdural space of the peri-lesional area. The rotor rod test was performed at preoperative state[before MCA occlusion], and 1, 2, 3, 4, 6, 8 and 10 weeks after the cell therapy. Results : The motor functions that were assessed by rotor rod test at 1 week of the cell therapy were nearly zero among the experimental groups. However, there was apparent motor function recovery after 2 weeks and 4 weeks of cell injection in intravenously treated rats and peri-lesionaly treated rats, respectively, while there was no significant improvement till 8 weeks in vehicle treated rats. Conclusion : These results demonstrate that the adipose derived stem cell treatment improves motor function recovery in rats with cerebral infarction.

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.

Background and objective: Recreation or activities in forest are regarded as therapy. Many forest therapy programs have been developed and assessed in the domestic. This study was conducted to investigate the effect of the forest therapy program on academic and job-seeking stress in college students. Methods: Thirty five subjects were selected as the experimental group and 25 as the control group, and 29 subjects in the experimental group and 11 in the control group participated in the follow-up test to verify the persistence of stress reduction effects. The forest therapy program was carried out once a week for 2 hours each from September 4 to December 4, 2018, adding up to total eight sessions. Results: The experimental group showed statistically significant reduction in both academic stress and job-seeking stress, whereas the control group did not. For the persistence of the forest therapy program, the experimental group did not show a statistically significant difference between the posttest and the follow-up test, and thus the stress reduction effect was maintained. Conclusion: This study proved the reduction of academic and job-seeking stress in forest therapy programs and the persistence of the stress reduction effect of the forest therapy program. The result is consistent with the Stress Recovery Theory (SRT) that shows the stress reduction effect of nature. In addition, it has significance in that it has verified that the program using the forest on campus can reduce stress of most college students.

In an attempt to observe the effects obtained by the regular physical training, nine soldiers performed regularly the rope-skipping for nine weeks. All subjects were healthy and did not experience any special military training Programs. During the course of the training, their cardiopulmonary functions were measured in the resting and the Post-exercise recovery periods, and the values were compared with ones of the pre-trained. The test exercises loaded to the subjects were rope-skipping and step-rising & falling. The results obtained were as follows: 1) By the training, heart rates decreased very significantly in the resting and post-exercise recovery periods. And the effects began to bring out at the early stage, about the 7th day. 2) As the duration of the training increased, the systolic blood pressures decreased meaningfully in the resting and recovery periods. 3) Only in the early recovery phase after the exercise of the rope·skipping, the respiration rates decreased significantly by the training. 4) The lighter the intensity of the test exercise loaded was, the more prominent the effect of the physical training on the cardiopulmonary functions was. The above results suggest that the 9 week training of the rope-skipping would bring about the enhancement of the cardiopulmonary functions.

Physical activity and exercise can promote sensorimotor recovery from central nerve injury. It has been suggested that the functional recovery promoted by exercise training after spinal cord injury might be associated with insulin-like growth factor-I in the inflicted muscle. To investigate morphological and biochemical change of the soleus muscle after spinal cord injury, all tissues were used for H&E, immunofluorescence staining and Western blot. Also, BBB-test was used to evaluate behavioral improvement after spinal cord contusion. Thirty male Sprague-Dawley rats ($230{\pm}10\;g$; 7week in age) were assigned equally to three different groups; Normal (n=10), SCI (n=10), SCI+TMT (n=10). Every rat in SCI and SCI+TMT groups underwent laminectomy at T9 level and then contusion on the exposed spinal cord site in anesthetized condition. After one week-recovery from contusion, every rat in the SCI+TMT group exercised on a motorized treadmill for 30min/d, 5d/wk for 7wks. TMT followed by injury increased IGF-I induction levels in the soleus muscle and inhibited muscle atrophy. Behavioral scales for 4 and 8 weeks after spinal cord injury were improved in the SCI+TMT group compared to the SCI group. These results suggest that treadmill exercise after spinal cord injury might promote functional recovery along with muscle regrowth through the up-regulation of IGF-1 in muscle tissue.
