The purpose of study was to measure to body Surface area and the rational rate of Korean adult's women. The subjects are 20 years old to 49 years old women (Their bust width ranges from 74.5 to 101.5 cm, the height from 144.6 to 163.3 cm, the weight from 44.2 to 74.0 kg, Rohrer Index from 1. 02 to 1. 89). As the experimental method, both the gypsum method, by which the shape of body can be copied as it is, and weighing method, from which planed body surface area can be measured with consistant thickness of polypropylene film used. The results were obtained as follows. 1. After dividing the Korean adult's women into four groups (single and married women in their twenties, those in their thirties, those in their fourties). The change of body surface area was reviewed in accordance with age groups. No great difference among age group was showed in whole body surface area. 2. average value of body surface area is 1, 514m^2 and the part of trunk shows the biggest difference to the age groups. 3. After dividing the middle of body into two groups, the relation of symmetry of each parts is reviewed with difference in body surface area. The results shows that the part of head & neck and lower limbs are symmetrical. The part of trunk and upper limbs are unsymmetrical. 4. Regional rates of each part of whole body surface area are follows. head $4.98\%$, each-lobes $0.46\%$, neck $2.01\%$, face$2.48\%$, upper trunk $19.64\%$, lower trunk $13.91\%$, upper armpits $1.76\%$, lower armpits $12.52\%$, hands $4.64\%$, thighs $18.89\%$, lower legs$13.10\%$, feet $6.01\%$.

The purposes of this study were to assess dynamic stability toward pelvis-spine column distortion during running and to compare the typical three-dimensional angular kinematics of the trunk motion; cervical, thoracic, lumbar segment spine and the pelvis from the multi-segmental spine model between exercise group and non-exercise group. Subjects were recruited as exercise healthy women on regular basis (group A, n=10) and non-exercise idiopathic scoliosis women (group B, n=10). Data was collected by using a vicon motion capture system (MX-T40, UK). The pelvis, spine segments column and lower limbs analysiaed through the 3D kinematic angular ROM pattern. There were significant differences in the time-space variables, the rotation motion of knee joint in lower limbs and the pelvis variables; obliquity in side bending, inter/outer rotation in twisting during running leg movement. There were significant differences in the spinal column that is lower-lumbar, upper-lumbar, upper-thoracic, mid-upper thoracic, mid-lower thoracic, lower thoracic and cervical spine at inclination, lateral bending and twist rotation between group A and group B (<.05, <.01 and <.001). As a results, group B had more restrictive motion than group A in the spinal column and leg movement behaved like a 'shock absorber". And the number of asymmetry index (AI) showed that group B was much lager unbalance than group A. In conclusion, non-exercise group was known to much more influence the dynamic stability of equilibrium for bilateral balance. These finding suggested that dynamic stability aimed at increasing balance of the trunk ROM must involve methods and strategies intended to reduce left/right asymmetry and the exercise injury.

Background: Echocardiography involves strenuous postures of the upper limbs. This study explored the physical workload in the neck and upper limbs in sonographers performing echocardiography, and the extent to which the workload differs from than in other work tasks (other sonographic examinations, and nonsonographic tasks). Methods: The physical load was assessed by inclinometry, goniometry, and electromyography methods in 33 female sonographers during authentic work using three different echocardiography techniques and other work tasks. Results: Echocardiography was characterized by low velocities of the head, arms, and wrists, and a low proportion of muscular resting time in the forearms, in the transducer limb, and the computer limb. The transducer limb was more elevated in one of the techniques, but this technique also involved a higher proportion of muscular resting time of the trapezius muscle. We also found a high proportion of awkward wrist postures in the transducer wrist in all three techniques; in one due to prolonged flexion, and in the others due to prolonged extension. Other work tasks were less static, and were performed with higher upper arm and wrist velocities. Conclusion: None of the three echocardiography techniques was optimal concerning physical workload. Thus, to achieve more variation in physical load we recommend that the equipment be arranged so that the sonographer can alternate between two different techniques during the workday. We also propose alternation between echocardiography and nonsonographic tasks, in order to introduce variation in the physical workload. Clinical expertise should be used to achieve further improvements.

This study analyzed the occurrence of abnormal muscle coactivations based on the assistance of upper limb weight during reaching task in stroke patients. Nine chronic stroke survivors with hemiplegia performed reaching tasks using a programmable haptic robot. Electromyography (EMG) coactivation levels in the upper limb muscles were analyzed using a linear model describing the activation levels of two muscles when the patient's upper limb weight was assisted at 0%, 25%, and 50%. As the upper limb weight assistance of the haptic robot decreased, the magnitude of the EMG signal in both the deltoid and biceps muscles increased simultaneously on both the paretic and non-paretic sides. However, no difference was found between the paretic and non-paretic sides when comparing the slope of the linear model describing the activation relationship between the deltoid and biceps. The aforementioned results suggest that in some stroke survivors, the deltoids, triceps, and biceps on the paretic side may not be abnormally coupled when supporting the upper limbs against gravity. Furthermore, these results suggest that the combination of haptic robots and EMG analysis might be utilized for evaluating abnormal coactivations in stroke patients.

Cold hypersensitivity is excessive sensitivity of each body part, particularly limbs and low backs, but sometimes it affects upper abdomen region in G-I trouble patients. We conducted this research on 69 patients who came and took the both exam of gastroscopy and D.I.T.I. in Kangnam korean hospital Kyung Hee university. So, we researched the significance of temperature deviations on upper abdomen which was studied separately by gastritis group, digestive function group and H. pylori group. The result was : 1. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of gastritis group was significant, it means that patients with severe gastritis have more significant cold hypersensitivity in upper abdomen than the patients who has not gastritis(p<0.005). 2. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of indigestive patients in digestive function group was significant(p<0.05) 3. The temperature deviation of Zhongwan(Ren12)-Danzhong(Ren17) of H.pylori positive patients in H.pylori group was not significant. 4. The clinical relationship or tendency was not found both between H.pylori group and gastritis group and between H.pylori group and digestive function group.

NREX, an upper limb exoskeleton robot, was developed at the National Rehabilitation Center to assist in the upper limb movements of subjects with weak muscular strength and control ability of the upper limbs, such as those with hemiplegia. For the free movement of the shoulder of the existing NREX, three passive joints were added, which improved its wearability. For the flexion/extension movement and internal/external rotation movement of the shoulder of the robot, the ball lock pin is used to fix or rotate the passive joint. The force and torque between a human and a robot were measured and analyzed in a reaching movement for four targets using a six-axis force/torque sensor for 20 able-bodied subjects. The addition of two passive joints to allow the user to rotate the shoulder can confirm that the average force of the upper limb must be 31.6% less and the torque must be 48.9% less to perform the movement related to the axis of rotation.

Objectives : this study is to see if there is a significance in thermal differences of acupoints in diagnosis and treatment period of facial paralysis and to substantiate the validity of acupuncture and moxibustion treatment for it. Methods : 1. By using DITI, thermal differences of acupoints on the face and the upper limbs of 13 Bell's palsy patients were measured around 3 days after an attack of the disease. These 13 patients, whose treatment progress was monitored up to 6 months after attack, were among the inpatients and outpatients of oriental internal medicine of National Medical Center from July 1 to August 31. 2. The patients were divided into 1month, 2-3months, 4months, 6months groups according to the occasion of improvement and thermal averages of each treatment period measured. Results : When it takes within 1 month for the condition of facial paralysis to change for the better, DITI image shows the temperature of the affected face parts and arms is higher than that of the non-affected parts. However, when it takes more than 4 months, the temperature of the affected face parts and arms on DITI image is lower than that of the non-affected parts. Conclusions : Hereby, prognosis of the disease and necessary time for the treatment can be presumed through DITI screening after an occurrence of facial paralysis. Also, condition of the disease is reflected by thermal differences of acupoints for Bell's palsy treatment that are in accordance with the theory of meridian on the face. This supports the efficacy of acupuncture and moxibustion treatment for this disease.

This study was carried out to determine the influencing of electrical stimulation to cervicothoracic sympathetic ganglion(CTSG; stellate ganglion) u the sympathetic tone. For the purpose of this study. the stimulation was given to both the interferential current stimulation(ICS: AMF 100Hz) group consisting of 10 person(males 8, females 2) and the transcutaneous nerve electrical stimulation(TENS: 100 Hz) group of 10(males 7, females 3) in the right side of the trachea with probe electrodes. Then. the temperature changes on the surfaces of the forehead. cheek, neck and internal ear of cephalocervix, which is subject to the influence of the cervicothoracic sympathetic ganglion, and the palm. which is the end of the upper limbs. measured before. immediately alter. 10 minutes after and 20 minutes after experiment. The results are summarized as follows. 1. The emergence of remarkable Horner's symptoms which appear due to the changes of the tone of cervicothoracic sympathetic ganglion was not seen. However, in the interferential current stimulation group there were two felt the sense of warmth in the facial region and one person who felt it in the upper limbs, and in the transcutaneous nerve electrical stimulation group there was each one person who felt the sense of warmth in the facial region and in the upper limbs, respectively. Both groups have each one person who felt the sense of oppression in the eyelids. Three persons of the interferential current stimulation group and two persons of the transcutaneous nerve electrical stimulation group have the sense of hoarse voice or numbness in the neck. These are the symptoms that appeared during stimulation, so it is difficult for them to be considered as the direct effects of the changes of the tone of cervicothoracic sympathetic ganglion. 2. The t-test was performed to determine the significance between the right, which is the experimental side, and the left, which is the non-experimental side. Significance between the right, which is the experimental side, and the left, which is the non-experimental side. Significant changes were seen in the necks of the interferential current stimulation group and in the cheeks and internal ears of the transcutaneous nerve electrical stimulation immediately after experiment(P<.05). And the interferential current stimulation group showed a very high significance in the cheeks immediately after experiment and in the necks ten minutes after experiment(p<.01). Therefore, it could be seen that the electrical stimulation had an influencing on the changes of body temperature of the cephalocervix. 3. In both the interferential current stimulation group and the transcutaneous nerve electrical stimulation group, the forecheads, checks and necks of the cephalocervix in the experimental side(right) rather than the non-experimental side(left) had mostly a statistically significant rise in temperature immediately after experiment. The one-way ANOVA was carried out to determine the temperature change of on the surface of the body with the lapse of time; before, immediately after, ten minutes after and tewenty minutes after experiment. But no statistical significance was found from both the right and left sides.

Background: Pharmacological and non-pharmacological therapies have been used to treat patients with chemotherapy-induced peripheral neuropathy (CIPN). However, the effect of therapies in cancer patients has yet to be investigated comprehensively. We hypothesized that cyclic thermal therapy would improve blood flow and microcirculation and improve the symptoms driven by CIPN. Methods: The criteria of assessment were blood volume in region of interest (ROI) in the images, and European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20 questionnaire scores. The blood volume was quantified by using red blood cell (RBC) scintigraphy. All patients were treated 10 times during 10 days. The thermal stimulations, between 15° and 41°, were repeatedly delivered to the patient's hands. Results: The total score of the questionnaires, the score of questions related to the upper limbs, the score of questions closely related to the upper limbs, and the score excluding the upper limbs questions was decreased. The blood volume was decreased, and the variance of blood volume was decreased. During cooling stimulation, the blood volume was decreased, and its variance was decreased. During warming stimulation, the blood volume was decreased, and its variance was decreased. Conclusions: We suggest that cyclic thermal therapy is useful to alleviate CIPN symptoms by blood circulation improvement. RBC scintigraphy can provide the quantitative information on blood volume under certain conditions such as stress, as well as rest, in peripheral tissue.
