This study was a quasi-experimental study of nonequivalent control group pretest- posttest design to investigate the effect of home rehabilitation exercise program on the physical and psychological functions of home stayed chronic hemiplegic stroke patients. The data were collected during the period of May 20th to August 15th, 200l. The subjects for this study were 40 hemiplegic stroke patients with the experimental group consisting of 19 patients and the control group being composed of 21 patients. The patients selected for this study were: (a)living in J city who had been diagnosed with stroke and at home after being discharged from the hospital, (b) suffering from stroke for 6 months to 5 years, (c) without recognition disorder with the MMSE-K(Mini-Mental State Examination-K)score above 25, (d) below 2 on the modified Ashworth scale, (e)free from heart and pulmonary disease, (f)able to walk beyond 15 minutes for themselves, (g) not taking regular exercises. The program for the experimental group provided 8 weeks' home rehabilitation exercise, two times of group education during the first week and individual education and supportive care after the second week through home visiting and telephoning more than once a week. The amount of time spent on rehabilitation exercise by the experimental group was 35 to 50 minutes a day, three times a week. In order to understand the effects of experiment the two groups were compared and verified by measuring the physical and psychological functions of both groups. The data were analysed by $\chi^{2}-test$, paired t-test and unpaired t-test and ANCOVA through SAS/PC program. The results of the study were as follows: 1. In terms of physical variables: grip strength. lower extremity muscle strength, walking time, ADL and serum lipid levels 1) There was no significant difference in the unaffected and affected grip strength between the two groups, even though the unaffected and affected grip strength was more improved in the experimental group than in the control group. 2) There was no significant difference in the unaffected lower extremity muscle strength between the two groups, even though the unaffected lower extremity muscle strength was more improved in the experimental group than in the control group. There was no significant difference either in the affected lower extremity muscle strength between the two groups, even though the affected lower extremity muscle strength was more improved in the experimental group than in the control group. 3) There was significant difference in walking time between the two groups. Walking time was significantly reduced in the experimental group whereas it increased in the control group. 4) There was significant difference in ADL score between the two groups. ADL score was significantly increased in the experimental group, but it significantly decreased in the control group. 5) There was significant difference in serum total cholesterol level between the two groups. After experiment the serum T-C level became lower in the experimental group whereas it became sigficantly higher in the control group. 2. In terms of psychological variables: depression and self-esteem 1) There was no significant difference in the depression between the two groups, even though the depression showed constant in the experimental group, but it showed a significant increase in the control group. 2) There was no significant difference in the self-esteem between the two groups, even though the self-esteem showed some increase in the experimental group, but it significant decrease in the control group. As shown above, the results of 8 weeks' home rehabilitation exercise program for chronic hemiplegic stroke patients produced positive effects on walking time, ADL score and serum T-C level, shortening walking time, improving activities of daily living(ADL) and lowering serum total cholesterol level.

All living organisms exhibit the characteristics of aging, such as skin wrinkle formation, muscle degeneration, cataracts, and hair graying as the number of aged cells increases over time. Senescence, which is known as a key cause of aging, is directly related to the aging of living organisms because cells are aged by external and internal factors and eventually cell proliferation is stopped. Senescence is caused by the gradual shortening of the telomere with cell division, and lifespan is determined by the length of the telomere. Recently, it has been found that the histone deacetylase, which can influence gene expression, is not only involved in yeast but also deeply involved in anti-aging mechanisms in both C. elegans and humans. It was also discovered that old cells play a decisive role in the aging phenomenon, and it has been reported that it is possible to promote the proliferation of young cells and delay aging by removing these senescent cells from the inside. Therefore, in order to develop potential anti-aging agents in the future, research should begin with an in-depth study of telomerase activators, sirtuin activators, and senolytics.

The present study was conducted to evaluate the effects of high levels of nutrients on the growth performance, blood metabolites and carcass characteristics of Hanwoo cattle. Eighteen Hanwoo steers were fed two types of diets: 1) Nine animals were fed the conventional diet including typical levels of crude protein (CP) and total digestive nutrients (TDN), and 2) Nine animals were fed the treatment diet including high levels of CP and TDN. The average body weight (BW) and dry matter intake (DMI) were greater (P < 0.05) in the treatment group than in the conventional group at early and late fattening stages. Also, in the treatment group, the average daily gain (ADG) was greater (P < 0.05) at the late fattening stage. The serum total lipid and cholesterol levels were higher (P < 0.05) in the late fattening stage of treatment group. The carcass weight, total fat weight, longissimus muscle area and the grade of meat quality were also greater (P < 0.05) in the treatment group than the conventional diet group. This study demonstrates that high levels of CP and TDN exhibit a positive effect on the growth performance and carcass characteristics, indicating that high levels of CP and TDN can be used as a cost-effective feeding program for Hanwoo cattle by shortening the feeding period.

The purposes of this study were to compare pelvic tilt before and after manipulation of sacroiliac joint in 31 low back pain patients (11 males, 20 females) with sacroiliac joint dysfunction. The sacroiliac joint of patients was manipulated on the side of anterior pelvic tilt, using the technique described by Stoddard (1962) and Greenmann (1996). I used this technique because it usually eliminated sacroiliac joint dysfunction in one treatment session. SPSS for window computer system was used to analyze the data. Also t-test was performed for comparison of pelvic tilt angle before and after manipulation, and Pearson product-moment correlation analysis was performed for intratester reliability for measurements of pelvic tilt angle before and after manipulation. The result were as follows: 1. Intratester reliability was good for measures of pelvic tilt (r=.98). 2. The pelvic tilt after manipulation was significantly decreased (mean=$3.40^{\circ}$) compared with the pelvic tilt before manipulation (p=.001). All subjects showed asymmetrical right versus left pelvic tilt before manipulation. 40% of subjects showed decreased asymmetrical right versus left pelvic tilt after manipulation, and 60% of subjects showed symmetrical right versus left pelvic tilt after manipulation. I think that pelvic tilt asymmetry with hypomobility due to loss of joint play could be symmetrized by manipulation or mobilization, but pelvic tilt asymmetry with unilateral pelvic muscle shortening could not be symmetrized by manipulation or mobilization without relaxation and stretching of shortened muscles.

Maxillary canting and vertical shortening of the unilateral mandibular ramus height is common in cases of severe facial asymmetry. Normally, mandibular distraction osteogenesis (DO) with horizontal osteotomy at the ascending ramus is used for vertical lengthening of the mandibular ramus to correct facial asymmetry with an absolute shortened ascending ramus. In this case report, vertical lengthening of the ascending ramus was performed successfully with unilateral DO and sagittal split ramus osteotomy (SSRO), where the posterior part of the distal segment can be distracted simultaneously in an inferior direction with maxillary DO, resulting in a lengthening of the medial pterygoid muscle. This case describes the acquired unilateral mandibular hypoplasia caused by a condylar fracture at an early age, which resulted in abnormal mandibular development that ultimately caused severe facial trismus. The treatment of this case included two-stage surgery consisting of bimaxillary distraction osteogenesis for gradual lengthening of the unilateral facial height followed by secondary orthognathic surgery to correct the transverse asymmetry. At the one year follow-up after SSRO, the vertical length was maintained without complications.

Between December 1993 and December 1994, fifty-eight percent of the mitral valve patients[33/57 had undergone mitral valve repair. Their mean age was 49[SD-16 years[range 11 - 75 and they were consisted with 15 males and 18 females. The causes of mitral disease in 33 patients were classified as follows: 19 cases[58% were degenerative, 9[27% were rheumatic, 3[9% were congenital and 2[6% were infectious. Carpentier`s functional classification was consisted with Class I 4 cases[12% , II 25 [76% and III 4 [12% . Surgical techniques included prosthetic annuloplasty in 32 cases[97% , leaflet resection in 16[48% , chorda shortening in 13[39% , chorda transfer in 9[27% , new chorda formation in 7[21% , commissurotomy in 7[21% , leaflet mobilization in 4[12% , chorda resection in 3[9% , papillary muscle splitting in 2[6% , cleft repair in 2[6% , leaflet patching in 1[3% and vegetation removal in 1[3% . Average number of mitral anatomical lesions per patient was 3.3 and We used average 3.0 procedures upon mitral valve apparatus per patient. Intraoperative transesophageal echocardiography was carried out in 27 patients[82% for providing an immediate and accurate assessment of the adequacy of the reconstruction before closure of the chest. Operative mortality was absent. The mean functional class[NYHA was 2.87 preoperative and improved to 1.03 postoperatively. Postoperative Doppler echocardiography showed much improvement from grade II MR[5 , grade III[5 , grade IV[21 to no MR[26 , only trace MR[3 , grade III MR[2 . Postoperative mean mitral valve area was 2.4$\pm$0.6cm2[range 1.5 - 4.0 . We conclude that cautiously evaluated mitral valve reconstruction is stable and predictable operation with minimal postoperative left ventricular dysfunction.

Submucosal type cleft palate is a kind of cleft palate. A submucosal cleft may result in shortening of the anteroposterior dimension of the hard or soft palates or both. The increased distance along with the lack of muscle connection in the soft palate usually accounts for the lack of palatopharyngeal function in patients with submucosal cleft. Resonance disorders which is found in cleft patients show hypernasality or hyponasality. Many cases of submucosal type cleft palate patients visit our clinics due to hypernasality. In this study, resonance disorders was evaluated through nasalance test. Experimental group was composed of submucosal type cleft palate patients. The patients were treated by a so-called combined therapy, i.e., operation and speech training. To observe the changing pattern by surgery, nasalance test was carried out one time before surgery and three times after surgery. Nasometer II was used as a examination. The questionaire was filled with single vowels & diphthongs. The mean nasalance score of the child was significantly lower than that of the adult at every vowel. An early age at operation (under 10 years) was that a better functional result was achieved with patients. The mean nasalance score of /i/ was highest and that of /a/ was the lowest. The result of corrective surgery in selected cases has achieved improvement in all cases. Hypernasality has been consistently diminished. he operation.

Adaptive lengthening or shortening of the nervous system is essential in order for a part of the body to move without restriction or resistance. Up until now, most treatment concepts have focused on normalizing muscle tone and preventing contractures in muscles and joint, but, as Butler and Gifford have brought to the attention of therapists, when a part of the body moves, nerves are required to move as well, so that the integration of nervous system mobilization in treatment is equally important. As the main function of the nervous system is impulse conduction, it is obvious therefore that adaptive lengthening, both centrally and peripherally, is essential in order to accommodate the enormous variety and extent of body movements and postures used in everyday life impeding news conduction. In present day manual therapy, most physical therapist mobilize the nervous system inadvertently. Probably what may make it more difficult is that, for most physical therapist it is a relatively new tissue to contemplate, at least in biomechanical terms, and basic knowledge of structure is generally less than if joints and muscles. The purpose of this study was to introduce the nervous system mobilization to a physical therapist who is primary a clinician and who has concerned in the areas of biomechanics and pathology looking far answers to the clinical Problems.

Background Congenital muscular torticollis (CMT) is characterized by persistent head tilt toward the affected side. No consensus exists regarding the cause of this disorder. In this study, we analyzed various clinical factors in patients with CMT who were treated with surgical release. This analysis enabled us to identify potential causative factors of CMT and to establish a basis for surgical interventions. Methods In total, 584 patients who underwent surgical intervention for CMT from October 2007 to December 2016 were included in this study. Their demographic characteristics, birthrelated factors, and clinical features were analyzed. Results Data from 525 patients were analyzed in this study after exclusion of those with insufficient information. Before birth, 31 patients (5.9%) were diagnosed with oligohydramnios, and 87 (16.6%) had a breech presentation. Seven (1.3%) cases of clavicle fracture and two (0.4%) cases of cephalohematoma were noted at birth. Before surgery, 397 patients (75.6%) underwent physiotherapy and 128 patients (24.4%) did not. The duration of physiotherapy ranged from 1 to 50 months (average, 6 months). Conclusions Our study shows that 16.6% of the CMT patients presented in the breech position, which is a much higher rate than that observed in the general population (3%-4%). We hypothesize that being in the breech position as a fetus appears to exert a significant influence on shortening and fibrosis of the sternocleidomastoid muscle.

Objectives This study examined recent domestic and international clinical research trends in Gua sha therapy to suggest future direction for research. Methods We used six domestic and international databases (Research Information Sharing Service, Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, PubMed, Embase, Cochrane Library) to select clinical studies with an original text in English or Korean published after 2018. Results Finally, 55 studies were selected. Randomized controlled trials accounted for the largest amount with 42 studies. Instrument assisted soft tissue mobilization was the most frequent term referring to Gua sha. Muscle shortening, limited range of motion, and plantar fasciitis were the most common symptoms, with six cases each. Additionally, there were two studies targeting symptoms other than the musculoskeletal system. Conclusions Additional research is needed on the effects of Gua sha therapy on the back of the lower extremities and hip joints, and research is needed on the possibility of their clinical use for diseases or symptoms other than those of the musculoskeletal system. And standards for the terminology of Gua sha and the types and methods of applied interventions are needed.
