Purpose: The purpose of this study was to determine the effect of early Robot-assisted training on gait ability, function and ADL in patients with stroke. Methods: 26 patients with stroke were recruited for this study. The subjects were randomly assigned to either the experimental group (EG) or the control group (CG), with 13 patients in each group. All subjects received a routine physical therapy. The robot-assisted training was for 30 min in the case of the EG subjects. The assessment tools of this study involved the gait ability, balance ability, function and ADL. The measurements were recorded before the intervention and after the intervention. Results: EG subjects and CG subjects, the variables measured after the intervention significantly differed from gait ability, balance ability, function and ADL without the FMA (p<0.05). The FMA was only effective experimental group after intervention. Also, there were significant differences in gait ability, balance ability, function and ADL without the FMA at post-test between the 2 groups (p<0.05). Conclusion: The findings indicate that early robot-assisted training exerts a positive effect on gait ability, balance ability, function and ADL in patients with stroke. This result indicates the possibility of application of the early Robot-assisted training to the management for stroke patients. Further studies are required to generalize the result for this study.

The purposes of this study were to investigate the therapeutic effects of an early exercise program after mastectomy and to provide the early exercise program protocol for patients who had undergone mastectomy. The subjects were seventy women who were diagnosed with breast cancer. They were randomly as signed either to a experimental group (n=35) that received early postoperative exercise program or to a control group (n=35) that received only education by nurses. Data were obtained for each patient from goniometric measurements of shoulder flexion, abduction, external rotation, 10 elements of functional performance, and subjective pain evaluation using visual analogue scale (VAS). All variables were measured preoperatively, three days postoperatively, and one month postoperatively. Data were compared by groups using independent t-test and Mann-Whitney U test for parametric or non-parametric data, respectively. There were no significant differences between the groups for all variables preoperatively and at three days postoperatively. But there were significant differences at one month postoperatively. The experimental group showed a statistically significant increases in shoulder flexion, abduction, and external rotation and in the pain VAS at one month postoperatively (p<.05). Also, at one month postoperatively, the experimental group had less difficulty with three elements of functional performance-doing up a 'back' zippered article of clothing, reaching the ipsilateral scapula, and contralateral scapula with the fingers on the operated side-than the control group (p<.05). The results of this study suggest that, after mastectomy, the early exercise program conducted by a well-trained physical therapist can make a significant contribution to the return of more normal shoulder function and activities of daily living and to an increased quality of life.

This study was designed to investigate the effect of early protein undernutrition of rats on later susceptibility to lead poisoning. Weanling rats, weighing about 55 grams, were malnourished by feeding low protein diets ( 12% and 5% casein diet ) during the four weeks of protein deprivation period. For the following 5 weeks, the malnourished rats were fed with 25% casein diet as rehabilitation diet. After the rehabilitation period, all rats were fed with 25% casein diet and the drinking water containing 2000ppm-Pb during the four weeks. The results obtained were as follows ; 1 ) Feed intake, body weight gain and food efficiency ratio were reduced in all rats exposed to lead, especially in rats fed with 5% casein diet during the four weeks of weanling period. 2 ) Enlargement of kidney and spleen were observed in all rats exposed to lead and were more remarkable in rats fed with 5% casein diet. 3 ) In rats exposed to lead, activity of serum glutamic oxaloacetic transaminase ( S- GOT ) was significantly increased by increasing the degree of early protein deprivation, whereas hematocrit value was significantly decreased. Activity of serum glutamic pyruvic transaminase ( S- GPT ) was shown a tendency to increase by increasing the degree of early protein deprivation, but the difference was not significant. 4) In rats exposed to lead, the amount of lead accumulation in kidney was increased by increasing the degree of early protein deprivation. The significant increase was shown in rats fed with 5% casein diet during the four weeks of weanling period. The results of the experiment suggest that early protein undernutrition, even after some period of rehabilitation, may enhance the later susceptibility to lead poisoning.

This review highlights the ontogenesis and the differentiation of motor neuron in spinal cord, and introduce the survival motor neuron(SMN) which is associated with growth and survival of motor neurons. The differentiation of floor plate cells and motor neurons in the vertebrate neural tube appears to be induced by signals from the notochord. This signal is Sonic hedgehog(Shh). The early development of motor neurons involves the inductive action of Shh. The SMN gene is essential for embryonic viability. SMN mRNA is also expressed in virtually all cell types in spinal cord, including large motor neurons. The SMN protein is involved in RNA processing and during early embryonic development is necessary fer cell survival. Two SMN genes are present in 5q 13 in humans: the telomeric gene(SMNt), which is the SMA-determining gene, and the centromeric analog gene(SMNc). The majority of transcripts from the SMNt gene are full length but, major transcripts of the SMNc gene have a high degrees of alternative splicing and tend to have little or no exon 7. The SMN is involved in the RNA processing(the biogenesis of snRNPs and pre-mRNA splicing), the anti-apoptotic effects, and regulating gene expression.

PURPOSES : Concrete pavement has been used in the construction of the Jungbu expressway in 1987. More than 60% of the pavement on the expressway is currently made of concrete, but most has been used far beyond their design life. Pavement life has been extended through routine maintenance or overlay. However, the structural capacity of the pavement has reached its limit, and extensive rehabilitation/reconstruction with long time traffic blocking should be considered. The three following issues on concrete rehabilitation/reconstruction will be discussed: (1) economic comparison of asphalt inlay and asphalt overlay, (2) economic comparison preventive overlay on a section which is currently good and routine overlay on the section which will be poor, and (3) economic analysis of early-strength concrete when it is used in concrete reconstruction. METHODS : First, various life cycle cost analysis tools were compared, and the proper tool for the extensive rehabilitation/reconstruction was selected. Second, a sensitivity analysis of the selected tool was performed to find the influential input variables, which should be carefully selected in the analysis. Third, three case studies, which can be issues in the rehabilitation/reconstruction of the expressway concrete pavement in Korea, were performed. RESULTS : Asphalt overlay without milling the deteriorated concrete showed 18~25% lower life cycle cost than the current asphalt inlay with milling. The good current preventive overlay on the section was economically justified within the scope of this study. The construction cost limit of the early strength concrete was suggested to be economical for 1, 3, and 7 days of construction alternative opening. CONCLUSIONS : CA4PRS was a viable tool for comparing various rehabilitation/reconstruction issue alternatives. Several concrete issues associated with the rehabilitation/reconstruction of the deteriorated concrete pavement were discussed as mentioned above.

Objective To investigate differences in plantar pressure distribution between a normal gait and unpredictable slip events to predict the initiation of the slipping process. Methods Eleven male participants were enrolled. Subjects walked onto a wooden tile, and two layers of oily vinyl sheet were placed on the expected spot of the 4th step to induce a slip. An insole pressure-measuring system was used to monitor plantar pressure distribution. This system measured plantar pressure in four regions (the toes, metatarsal head, arch, and heel) for three events: the step during normal gait; the recovered step, when the subject recovered from a slip; and the uncorrected, harmful slipped step. Four variables were analyzed: peak pressure (PP), contact time (CT), the pressure-time integral (PTI), and the instant of peak pressure (IPP). Results The plantar pressure pattern in the heel was unique, as compared with other parts of the sole. In the heel, PP, CT, and PTI values were high in slipped and recovered steps compared with normal steps. The IPP differed markedly among the three steps. The IPPs in the heel for the three events were, in descending order (from latest to earliest), slipped, recovered, and normal steps, whereas in the other regions the order was normal, recovered, and slipped steps. Finally, the metatarsal head-to-heel IPP ratios for the normal, recovered, and slipped steps were $6.1{\pm}2.9$, $3.1{\pm}3.0$, and $2.2{\pm}2.5$, respectively. Conclusion A distinctive plantar pressure pattern in the heel might be useful for early detection of a slip event to prevent slip-related injuries.

Purpose : This study is to investigate difference in the isometric muscular function of knee joints according to the time of participation in rehabilitation exercise in patients who had anterior cruciate ligament reconstruction. Methods : The subjects of this study were patients by sports injury or accident in the sports rehabilitation center of G hospital. The early exercise program group (n=7) started functional ability exercise from 2 weeks after the surgery and the late exercise program group (n=7) from 6 weeks after the surgery. Statistical analysis was used repeated measure ANOVA to test mean difference by using SPSS 18.0 for windows. Results : First, as to quadriceps femoris muscle according to the time of participation in exercise program, significant difference was observed according to interaction and time. Second, as to hamstring muscle according to the time of participation in exercise program, significant difference was observed in muscle strength according to time. Conclusion : This results suggest that if the effect of exercise program is similar between the early starting group and the late starting group, it is not necessary to have a long period of fixation as in the late exercise program group but is desirable to start functional ability exercise early in order to relieve pains in the knee joints.

Objectives : The purpose of this study was to investigate the effect of chuna treatment(manipulation) on lumbar sprain caused by traffic accident in early stage, by analysis of the Heart Rate Variability(HRV) and Visual Analogue Scale(VAS). Methods : This study carried out on 20 patients who have received hospital treatment in Daejeon Univ. cheonan Oriental Hospital. Non-chuna group got acupuncture-therapy, herbal medication, physical therapy and Chuna group got all the therapies and chuna treatment. We measured HRV and VAS on 2nd, 4th day. Results : After being treated by our methods, Chuna group showed the inclination to balance between the sympathetic and parasympathetic nerve. In chuna group as compared with non-chuna group, an autonomic nerve activity and stress resistance showed the inclination to increase(p<0.05). And chuna treatment reduced the rate of stress increase. Conclusions : The results suggest that chuna treatment help traffic accident patients in early stage to reduce pain. Refer to autonomic nerve system, chuna treatment seem to do positive effect but Further long term study in a large scale is needed.

Avascular necrosis (AVN) of the humeral head is a rare, yet detrimental complication. Left untreated, humeral head AVN frequently progresses to subchondral fracturing and articular collapse. Cases of late-stage humeral head AVN commonly require invasive procedures including humeral head resurfacing, hemiarthroplasty, and total shoulder arthroplasty (TSA) to improve clinical outcomes. However, in cases of early-stage AVN, core decompression of the humeral head is a viable and efficacious short-term treatment option for patients with pre-collapse AVN of the humeral head to improve clinical outcomes and prevent disease progression. Several techniques have been described, however, a percutaneous, arthroscopic-assisted technique may allow for accurate staging and concomitant treatment of intraarticular pathology during surgery, although further long-term clinical studies are necessary to assess its overall outcomes compared with standard techniques. Biologic adjunctive treatments, including synthetic bone grafting, autologous mesenchymal stem cell/bone marrow grafts, and bone allografts are viable options for reducing the progression of AVN to further collapse in the short term, although long-term follow-up with sufficient study power is lacking in current clinical studies. Further long-term outcome studies are required to determine the longevity of core decompression as a conservative measure for early-stage AVN of the humeral head.
