Purpose：The purpose of this study were to determine whether changes of position might effect the chest expansion and pulmonary function of the 20s men obesity.
Methods：Thirty subjects with obesity(M:30, % fat>25.0) and thirty normal subjects(M:30, % fat<24.9) were participated in experiment. Subjects were assessed according to position changes(supine position, 45° lean sitting position, 90° sitting position) using chest length(chest length for resting, chest expansion) and pulmonary function (Tidal volume, Inspiratory capacity, Vital capacity, Inspiratory reserve volume, Expiratory reserve volume) by the CardioTouch 3000S(BIONET, USA). Repeated measure ANOVA was used to compare each region data of chest length and pulmonary function according to changes of position with obesity and normal subjects.
Results：These findings suggest that the obesity can be appear to low chest expansion and pulmonary function than normal subjects on position method. In comparison of three experimental position, supine position was more low.
Conclusion：This study showed position of the obesity appear low chest expansion and function of pulmonary volume than normal subjects, and thus it indicates that the pulmonary function of the obesity will be suggest objective respiratory data through the exercise program.
Purpose：To assess the relationship between post-stroke shoulder pain, motor function, and pain-related quality of life(QOL)Methods：Volunteer sample of 62 chronic stroke survivors with post-stroke shoulder pain and glenohumeral subluxation. The patients answered the question in shoulder pain with the Brief Pain Inventory question 12(BP1-12), Pain-related Quality of life(BPI-23). Therapists measured the performance of combined upper-limb movement including the hand-behind-neck(HBN), hand-behind-beck(HBB) maneuver, added passive pain-free shoulder external rotation range of motion, and Modified Ashworth Scale(MAS) score of the elbow flexors.
Physical performance assessments were used to measure basic activity daily living(Modified Barthel Index-self care, MBI-S/C), motor function of upper limb(Fugl-Meyer Upper/Lower Extremity, FM-U/E).
Results：Stepwise regression analyses indicated that post-stroke shoulder pain is associated with the BPI 23, but not with the FM-U/E, MBI-S/C. Thus, the presence of shoulder pain is more important predicting pain-related QOL than its degree in predicting motor function of upper limb and basic activity daily living.
Conclusion：Post-stroke shoulder pain was associated with reduced quality of life related to pain. The pain was not associated with the motor function of upper limb and basic activity daily living. The result imply that management of shoulder pain & anatomical position of shoulder joint after stroke should be emphasized.
This provides a further incentive to develop effective rehabilitation prevention and treatment strategies for post-stroke shoulder pain.
Objective：This study aims to examine how lumbar stabilization exercise and resistive exercise affect lumbar and lower extremity muscular strength of the aged.
Method：Randomly selected 15 female senior citizens aged 65 or older at S, Y, and J senior citizens’ center located in D city who meet the requirements for the study were divided into a resistive exercise group of 7and a stabilization exercise group of 8 for which 60-minute-exercise sessions were administered three times a week for 12 weeks. Measuring lumbar and lower extremity muscular strength was measured six weeks and 12weeks after exercise, respectively.
Results：First, both resistive exercises and stabilization exercises are effective to improve lumbar muscular strength.
Second, resistive exercise is effective to improve flexural muscle strength as well as lower extremity muscular strength, and stabilization exercise is effective for both flexion and extensor muscle strength.
Conclusion：The 12 week lumbar stabilization exercise program appeared to be effective to improve lumbar and lower extremity muscular strength of the aged. This indicates that applying this program to identify and prevent frequent risk factors of falling can lead to the prevention of secondary problem factors of falling accidents.
Purpose：This study was to investigate the prevention of spasticity with modified Ashworth scale(MAS) and range of motion(ROM) increase with goniometer in ankle joint by functional electrical stimulation(FES) and exercise for 4 weeks in chronic stroke patients.
Methods：60 chronic stroke patients participated in this study. The subjects were divided into 3 groups, FES group(n=20), FES+exercise group(n=20) and control croup(n=20). After FES application on tibialis anterior muscle by 35Hz for 4 weeks, the change of ankle joint movement was measured by goniometer.
Results：The spasticity in ankle joint was decreased greatly in FES and FES+excercise groups(p<.05), and the ROM of ankle joint was increased greatly in FES and FES +exercise groups(p<.05) than control group(p>.05).
Conclusion：It shows that FES made the angle of dorsiflexion in spastic ankle joint increase with functional improvement of tibialis anterior muscle in chronic stroke patients. This show that the FES is avaliable for facilitation of ROM and decrease of spasticity as a therapeutic tool.
Purpose：The present study invesigated the effect of changes in transversus abdominis thickness using ultrasonography during a hip adductor contraction.
Methods：This study was carred out in a volunteer sample of adults (N=30) without a history of low back pain or injury. In standing position, muscle thickness measurements of transversus abdominis(TrA) were measured using ultrasonography at rest and during a hip adducor contraction.
Results：TrA thickness were influenced a hip adductor during a voluntary contraction in people without LBP.
TrA showed significantly greater thickness changes on a hip adductor contraction.(p=0.000)Conclusion：The results from this study showed that the hip adductor contraction improves the ability to increase change in TrA thickness. These results can be a good evidence to prevent low back pain due to hip adductor weakness or genu varum deformity of knee osteoarthritis.
Purpose：The purposes of this study were to investigate the age-related difference in balance ability in the elderly over 65 years and to verify the clinical usefulness of the functional reach test (FRT) for balance evaluation of the elderly through the sensory organization test (SOT).
Methods：The subjects were forty-six community dwelling elderly people over 65 years old in order to verify the correlation of balance measures and to compare the balance ability. Balance was measured using the FRT and the six sub-equilibrium scores and the composite equilibrium score of the SOT. Pearson's product correlation coefficient was used to evaluate the relationships among these measurements of balance.
Results：There was a significant difference in functional reach by age in the elderly (p<.01). There was a significant negative correlation between the FRT and the age of the elderly (r=-.396, p<.01). There was also significant high positive correlation between the FRT and the eye closed sway surface (EC/SS) (r=.789, p<.01),and composite equilibrium score (r=.548, p<.01) of the SOT .
Conclusion：Thus, it is possible to use the FRT as a quantitative measure of balance, rather than the SOT,which is more expensive and complicated to evaluate elderly people. According to the results of this study, the use of the FRT is required clinically to objectively measure the balance of elderly people in the future.
Purpose：This study examined the feedback effect of real-time ultrasound imaging on the thickness of transversus abdominis(TrA), internal abdominal oblique(IO) and external abdominal oblique(EO) during abdominal hollowing exercise(AHE) in crook lying.
Methods：We performed this study on 30 healthy men who voluntarily consented to participate in this study after listening to its purpose and method. All subject were divided into an experimental group(n=15) with using the real-time ultrasound imaging feedback(RUIF) and a control group(n=15) without the RUIF The thickness changes between rest and AHE were compared between the two groups in crook lying.
Results：The difference in TrA and EO thickness changes between the groups were significant in crook lying (p<0.05).
Conclusion：The group with using real-time ultrasound imaging feedback showed a higher increase in the thickness of TrA than the other group without real-time ultrasound imaging feedback. And the thickness of EO in the group with using real-time ultrasound imaging feedback decreased than the other group without real-time ultrasound imaging feedback. If the muscle thickness can be regarded as an indicator of muscle activity, RUIF will be helpful for inducing the independent activity of TrA by reducing the activities of abdominal muscles such as EO.
Purpose：The purpose of this study was to determine effect of Medical Exercise therapy on walking ability and ankle muscles activation after stroke.
Method：Participants were randomly divided into either MET training group(n=12) and control group(n=12). All of participants had been receving a traditional rehabilitation program, 5 days a week. MET training group have additionally undergone for six weeks, 3 days a week, the MET program. But control group was not received any additional program except the traditional rehabilitation program. The 10 mWT, F8WT and 2 MWT to measure walking ability were carried out twice before and after training. Muscular activity of the ankle was estimated by analyzing the RMS of action potential for EMG in terms of tibialis anterior muscle(TA),soleus(SO), gastrocnemius medial head(GM), gastrocnemius lateral head(GL).
Rresults：At the walking ability, MET training group demonstrated a significant improvememt in the score of the 10 mWT(p<0.001), 2 MWT(p<0.05), but F8WT was not significant improvement(p>0.05). At the ankle muscle activation, MET training group demonstrated a significant improvememt in the RMS of the TA(p<0.01)and SO(p<0.05) but GM(p>0.05) and GL(p>0.05) were not significant improvement.
Conclusion：From these results of this study, MET training for 6 weeks has an effect on improvement of walking ability and ankle muscles activation after stroke.
Purpose：The purpose of this study was to examine the effects of using a pressure bio-feedback unit (PBFU)and a pelvic belt (PB) on the electromyographic (EMG) signal amplitude of the gluteus medius (Gmed) and the quadratus lumborum (QL) during hip abduction exercise when lying on the side.
Methods：Twenty able-bodied volunteers (10 male, 10 female) were recruited for this study. The EMG signal amplitude was randomly measured during hip abduction with preferred hip abduction (PHA), with PBFU, and with PB. The surface EMG signal was recorded from the Gmed and the QL. Data were analyzed using a one-way repeated ANOVA.
Results：Muscle activity of Gmed was significantly higher in PBFU and in PB than in PHA (p<.05). There were no significant difference between PBFU and PB(p>.05). Muscle activity of the QL was significantly lower in PB than in PHA(p<.05). The Gmed/QL muscle activity ratio was also significantly higher in PBFU and in PB than in PHA(p<.05), with no significant difference between PBFU and PB (p>.05).
Conclusion：Based on these findings, using a PBFU and a PB is an effective method to disassociate QL use from Gmed use during hip abduction exercises when lying on the side.

Purpose：The aims of this study was to identify the activation of the mirror neuron system during action observation in people with stroke and the difference between left hemisphere and right hemisphere and to provide possibility of the use of action observation as a clinical method for improving motor function after stroke.
Methods：Seventeen participants were asked to observe 3 different stimulation conditions for 80 seconds. A 30second rest period was given between stimulations. Electroencephalogram(EEG) signals from electrodes on the participant’s scalp were recorded during action observation. The activation of the mirror neuron system(MNS)between the picture observation condition and action observation condition was compared with a paired t-test.
An independent t-test was used to compare difference between C3 and C4 on the activation of the mirror neuron system in the action observation condition.
Results：Result of paired t-test showed a significantly decreased log ratio in the activation of the mirror neuron system in the action observation condition compared to the picture observation condition. Result of the independent t-test indicated no significant differences in the activation of the mirror neuron system in the right and left hemisphere.
Conclusion：The mirror neuron system showed greater activation in the action observation condition than in the picture observation condition and activation in the both hemisphere during action observation. We conclude that these findings suggest that this may possibly be an efficient clinical intervention method for improving motor function.
