In this paper, We investigated the characteristic analysis of flexibility and muscle strength for exercise to verify capacity in rehabilitation exercise of lumbar using lumbar strengthen exercise instrument. We have experiment in 20th years man and woman who are 20 subject with no medical history, we divided subjects into control group with no exercise and training group with lumbar strengthen exercise. We used Hi-Spine(Medicalscience.korea) also, provided exercise 40 minute a day, three days a week and progressed total four weeks. Moreover in our experiment, subjects exercised four postural position as lay down, sit, stand and stretch each ten minute. We measured trunk extension backward, trunk flexion forward, evaluation of based physical fitness and lumbar joint torque. The reults have shown that there more improved all for flexibility, based physical fitness and lumbar joint torque in training group than control group. We indicated that by rotating 3-D axis movement flatform of exercise instrument, muscle spindle in subject have been stimulated and these rotation direction and angle caused muscle tonus and contraction that makes muscle, flexibility and based physical fitness improve more. Our study can be used rehabilitation exercise program to aged people and patient with lumbar injury.

The purpose of this study is to investigate the effects of aerobic exercise and probiotics ingestion on motor learning and body weight in female mice during adolescence. The subjects were divided into six groups of variables, such as non-exercise, moderate, high-intensity exercise, probiotics ingestion, and non-probiotics, and then treated for four weeks. The vertical grid test was conducted before and after the treatment to evaluate motor learning and bodyweight. The high-intensity exercise and probiotics ingestion group showed fastest up, rotation, and down rate than the non-exercise group (p<.001). Also, a group that treated exercise and probiotics tended to record speedier performance than those that performed the only exercise. Comparing weight changes, the weight gain of a group that performed only moderate-intensity exercise was higher than that of a non-probiotics and non-exercise group (p=.032). Taken together, aerobic exercise during adolescence can help improve motor learning, and more efficient motor learning can be achieved when combined with probiotics ingestion.

Purpose : This study aims to examine effects of trunk strengthening exercise in three rigid cerebral palsy adolescents aged between 11 and 13 on their spinal segments and gait. Methods : 2A trunk strengthening program for proprioceptive neuromuscular facilitation was made focusing on improvement in their school life and mental and social activities during their school years, and then trunk strengthening exercise was applied to the three subjects for 30 minutes five times per week for four weeks. With the subjects in a static state, each group's gait analysis was made and maximum anterior flexion, maximum extension, maximum left and right lateral flexion, and cross rotation of the trunk were measured using Sonosens (Germany) prior to and after the intervention. Results : Assessment of spinal segment mobility with the subjects in a static state showed that the trunk muscle strengthening exercise increased their maximum joint movement angles from the right side to the center and rotational abilities of the cervical and lumbar spines. Gait analysis indicated increased movements in the thoracic and lumbar spines and relatively decreased anterior-posterior movement of the cervical spine. Conclusion : Trunk strengthening program is effective in enhancing spinal segment mobility and balance ability of cerebral palsy adolescents and considered able to be used together with diverse treatment interventions.

This paper describes the design of an ankle rehabilitation robot for the force measurement of a severe stroke patient staying in a bed ward. The developed ankle rehabilitation robot was attached to a three-axis force/torque sensor that could detect force Fx, Fz, and torque Tz and measure the ankle rotation force (Fx) exerted on the ankle and the signal force Fz and torque Tz to be used as a safety device. The robot was designed and manufactured for bedridden stroke patients, and the robot program was manufactured to perform the flexibility rehabilitation exercise for ankle bending and to measure the ankle force to judge the degree of rehabilitation. According to the result of the characteristics test of the developed rehabilitation robot, it was safely operated while the ankle-bending flexibility rehabilitation exercise and the emergency situation were performed. Therefore, it is thought that the developed rehabilitation robot can be used for severe stroke patients.

Purpose: This study aimed to investigate the effect of neck exercises using proprioceptive neuromuscular facilitation (PNF) on dysphagia and neck pain in stroke patients. Methods: This study included 20 patients with stroke who performed the following neck exercises using PNF: flexion, lateral flexion, and rotation. The PNF technique was repeated under the guidance of verbal commands from a physical therapist. The exercise program consisted of 5 times, 30-minute sessions each week for four weeks. The Mann Assessment of Swallowing Ability (MASA) and the visual analogue scale (VAS) were used to evaluate the patients before and after the training. Swallowing ability was evaluated using MASA, and the patients' pain was evaluated using VAS. All data were analyzed using SPSS 21.0. Results: Significant differences were observed for the MASA and VAS in the subjects: MASA was significantly improved (p<0.00) and VAS was significantlyincreased (p<0.00). Conclusion: The neck is a very important part of the body in stroke patients. Neck exercises using PNF are effective for improving dysphagia and decreasing neck pain in patients with stroke. Thus, neck exercises using PNF are very effective for stroke patients, and this approach would be effective in clinical practice.

The objective of this study was to determine the effect of exercise on a hemiparkinsonian rat model. Nigrostriatal dopamine cell lesions were produced by injecting 6-hydroxydopamine at the left medial forebrain bundle of rats. In this study, the rats were divided into the following 4 groups: the control group without any exercise, experimental group I with aqua-exercise (Exp I), experimental group II with balance exercise (Exp II) and experimental group III with complex exercise (aqua-exercise+balance exercise; (Exp III)). Exercises were applied to all the experimental groups after the operation. In order to observe the dopaminergic cell loss, we assessed the level of tyrosine hydroxylase (TH) expression in the midbrain of rats, and performed the apomorphine-induced rotation test at postoperative days (PDs) 7, 14, and 21. Experimental groups had significantly higher TH-immunoreactivity and behavioral performance than the control group. However, there was no difference in TH-immunoreactivity and behavioral performance across the experimental groups. These results suggest that the application of aqua-exercise and balance exercise could suppress dopaminergic cell loss in the substantia nigra of rat brains and could increase behavioral recovery in hemiparkinsonian rats.

The purpose of the study was to evaluate the effects of sling exercise program on muscle activity and cervical spine curvature of person with forward head posture. The subjects, 25 students, were divided into two groups. This experiment was intended to examine the muscle activity and cervical spine curvature while the subjects had performed the exercises to do for 2 times/week and 4 weeks. The factors of FHP were measured cranial vertical angle, cranial rotation angle, muscular activity and cervical spine curvature. Cervical spine curvature measured craniovertical, craniocervical, cervicohorizontal and upper cervical angle. Collected data were statistically analyzed by SPSS 10.0. After experiment for 4 weeks period, results were as following: Both group was significant difference of the results according to the CVA. Exercise group are more effective to increase muscle activity (p<.05), but cervical spine curvature was no significant difference. This result, we could find out there was a significant correlation between sling exercise and muscle activity, CVA and CRA.

Purpose: The primary purpose of this study was to investigate the effects of cervical stabilization exercise (CSE) on hamstring flexibility in patients with neck pain. A secondary purpose of this study was to investigate the effects of cervical range of motion (CROM) and craniovertebral angle (CVA). Methods: This study was a single-blind, randomized, comparative trial. Twenty patients were allocated into either the cranio-cervical flexion exercise (CCFE) group or the CSE group. Before and after the intervention, we measured straight leg raise (SLR), popliteal angle (PA), CROM, and CVA in the sitting and standing positions. Fisher's exact test, the Mann-Whitney test, and Wilcoxon's signed-rank test were used to analyze our data. Results: Both groups showed significant improvements in the value of SLR, PA, cervical extension, cervical rotation, and CVA in the standing position (both, p<.05) after intervention. However, only the CSE group showed significant improvements in cervical right lateral flexion (z=-2.209; p<.01) and cervical left lateral flexion (z=-2.537; p<.05) after intervention. The CSF group showed more significant improvements in SLR, PA, both cervical lateral flexions, and both cervical rotations than the CCFE group. Conclusions: The results of this study will guide future research in identifying the effectiveness of CSE. In conclusion, it can be inferred that CSE has a positive effect on SLR, PA, CROM, and CVA in the standing position in patients with chronic neck pain.

Background: This study was to investigate the effects of active stretching and stability exercise on piriformis muscle thickness and low back pain of male patients with chronic low back pain. Design: Randomized Controlled Trial. Methods: 45 male patients participated in this study. All subjects were randomly assigned. Subjects divided into 15 who underwent contract relaxation (CR) of the proprioceptive neuromuscular facilitation (PNF) to their hip joints, 15 who underwent a combination of isotonic (CI) of the PNF, and the rest 15 who underwent the two techniques (CR+CI). Real-time diagnostic ultrasound was used to measure thickness of the piriformis muscles. The visual analogue scale (VAS) was used to measure degrees of low back pain. A two-way repeated measures ANOVA was used to compare the average values. The SPSS 24.0 was used as the statistical program, and the significance level was set at .05. Results: The CR and the CR+CI groups had more decreased thickness of piriformis muscle when compared to the CI group. The CR+CI group had more decreased pain when compared to the CR and the CI groups. Conclusion: These results suggest that combination of stretching and stability exercise was effective on male patients with chronic low back pain showing limited hip medial rotation.

Purpose: This study aimed to investigate the effects of rehabilitation programs with coaching exercise (CE) or home exercise (HE) on shoulder pain, muscle strength, and daily living functions (DLF) in patients with shoulder impingement syndrome. Methods: With quasi-experimental design, thirty patients (15 CE and 15 HE) participated in rehabilitation programs for 12 weeks. At first, data were collected for pain and DLF using questionnaires with testing muscle strength and range of motion. Then, subjects were allowed to receive training on rehabilitation with structured training materials. CE group visited sports center three times a week at P hospital and HE group did self-exercise at home. Data were analyzed using SPSS program. Results: After 12 weeks, both groups showed statistically significant changes in improving pain, muscle strength, and DLF. Compare to HE group, CE group showed a statistically significant improvement in shoulder pain (p=.021), muscle strength in internal rotation (p=.001) and abduction (p=.013) and DLF (p=.012). Conclusion: Rehabilitation programs for patients with shoulder impingement syndrome were effective to improve pain, muscle strength, and DLF. Although CE would bring the better effects, it is possible to apply HE through structured education to patients who are difficult to visit hospitals.
