A significant injury of ligament or tendon that might result in hypermobility and/or instability has been termed connective tissue insufficiency (CTI). Load bearing on CTI can sometimes create a malfunction of the mechanoreceptor and this in turn can aggravate the problem thus creating a chronic condition. Prolotherapy means the injection of growth factors or growth factor stimulators into the fibroosseous junction of the disabled ligament, tendon or cartilages in order to strengthen and promote proliferation of the injured Connective tissue. In the case of frequent recurrence or unresponsiveness to conservative treatment including nerve blocks in the chronic musculoskeletal disorder. We obtained good results after the prolotherapy treatment. This study will report on 5 cases of prolotherapy treatment.

PURPOSE: It is known that work stress was linked to WRMDs in workplace. The purpose of this study was to identify the characteristics of work related musculoskeletal disorders (WRMDs) related to job stress among prosthetists and orthotists. METHODS: Eighty-six self-reported symptoms of discomfort (SRSD) and job stress were collected by questionnaire and analyzed. RESULTS: The results were as follows: Over 70% of respondents had WRMDs. The shoulder was the most painful region and each of "within 15 minutes", "once a week" and "severe moving or doing exercise" items were main characteristics in the SRSD. Finally, the "repetition of simple work" item in job stress ranked as resulting in "often discomfort" in over 43% of respondents. Additionally, there was a statistically significant correlation between job stress and pain intensity (p<.05, $r_s$=.36). CONCLUSION: Further studies are needed to identify the factors affecting musculoskeletal symptoms and job stress of prosthetists and orthotists in Korea.

The purpose of this study is to survey job stress and Musculoskeletal Disorder(MSDs) of workers in small plants with agricultural products. The subjects were comprised of 69 workers participated in "Helping the rural women to get the small businesses" project. The questionnaire surveys were Korean Occupational Stress Scale(KOSS), and Legal Risk Assessment of Musculoskeletal Disorders(KOSHA CODE H-30-2003). As a result of the survey, scores of KOSS 8 sub-items except for job demand were similar to that of Korea workers. Prevalence of MSDs symptoms of small plants workers was high percent (44.9%). And the rate according to kinds of product was significant difference at neck (p<0.01), lumbar (p<0.01), and leg (p<0.01). There was no significant difference between view person sign of MSDs and non MSDs according to sex, year, the number of workers, working years, working time per one day, rest time per one day, and subjective working intensity, but there were significant difference between high stress group and low stress group about MSDs at interpersonal conflict(p<0.05). Job stress and MSDs were important factor to workers of small plants producted agricultural products. Therefore, starting a business with small plats, workers consider interpersonal conflict and body part showing MSDs.

Objective: The objective this paper is to introduce the agricultural ergonomics and to show the importance of it in improving the agricultural works. Background: Despite of rapid advancement of technologies and adoption of modern mechanical equipments at farms in Korea, most of agricultural works have still remained manual and thus have regarded as one of the hardest works. With aging and feminization in rural areas, the need to improve agricultural works has grown quite much. Agricultural ergonomics have been known as a good tool in improving agricultural works around the world. Recently Korean government initiated a national program of providing assistive equipments to help farmers and a few ergonomists started to apply agricultural ergonomics in our rural villages as a part of this program. Method: This study reviewed how Ergonomics was used for the agricultural work. Results: Methods of Ergonomics which are used for the agricultural ergonomics and the simple procedure of the agricultural ergonomics were presented. Conclusion: It was found that agricultural works can be improved quite much using the agricultural ergonomics principle and the musculoskeletal stress of farmers can be reduced significantly.

Spinal injuries are common these days and are increasing due to the increasing sports activities, auto-related accidents, and occupational incidences. Most of spinal injuries of strain and sprain are associated with trauma and resulted in loss of optimal musculoskeletal system in spinal column area. Some of these injuries requires surgical treatments. Fortunately, some people with spinal disorder are achieving outstanding results with the chiropractic care which utilizes muscle stimulation and strengthening, traction therapy, and spinal adjustments. These treatments using chiropractic table can ease pain by restoring alignment, improving mobility, and relieving pain and stiffness in neck and spinal areas. The purpose of this study was thus to gather the comprehensive information about spinal injuries, to define the specific dimensions, and to recommend functions of chiropractic table specially suited for Korean. This study was an integrated approach in applying the concepts of biomechanical correction of the musculoskeletal system. Also, this study was to utilize a knowledge of physics, ergonomics, and rehabilitation to the development of spine cure medicine.

Purpose: The purposes of this study were to survey the extent of pain and discomfort in the musculoskeletal system among visiting housekeepers, above all concerning neck, shoulder, back, wrist, knee, and arm pain and to find possible relations between symptoms and various working conditions. Method: A questionnaire was answered by 174 woman visiting housekeepers living in Kyeonggi-do and Seoul from December 1, 2003 to February 30, 2004. The symptoms of musculoskeletal system were coded by the pain index which illustrates the extent of the symptoms, and analyzed in view of NIOSH guideline and Kim, et. al.'s notion. Result: 1. As to the complaint rate of subjective musculoskeletal symptoms by body region, the figure was the highest for shoulder with 78.2%, followed by back with 66.7%, knee 53.6%, neck 56.3%, wrist 40.2%, and arm 29.2%, respectively. The logistic analysis showed shoulder pain and arm pain have no relation with working and health conditions, and back pain was significantly related to current health condition. In same way, knee pain and wrist pain were found to be mainly related to marital status. 2. Following the NIOSH guideline, the positive rate of subjective musculoskeletal symptoms was found out in following order: shoulder 69.5%, back 59.2%, knee 54%, neck 46%, wrist 32.8%, and arm 25.3%. To investigate the main cause of each disease, the symptoms were classified by pain index, where the value of more than 3 comes to the NIOSH case, and analyzed in term of complaint rate using discrete logistical method : shoulder pain was highly related to the housekeeping time after work, back pain was to current health condition and the heavy weight carrying and neck, wrist, arm pain were commonly related to the ordinary health condition. For knee pain, working speed was a main cause. 3. In view of Kim et. al.'s standard, where the pain index is over 7, the positive rate was showed in order slightly different from previous analyses : shoulder 33.3%. knee 29.9%, back 28.2%, neck 17.2%, wrist 17.2%, and 16.7%. From the logistical analysis, insufficient rest was shown as the main cause of shoulder, back, arm and wrist pain. For neck pain, ordinary health condition was mainly related. In case of knee pain, any apparent relation is not found. Conclusion: According to the logistic regression analysis of musculoskeletal system, there was strong suggestion that the less insufficient physical rest, the more significant disorder complaint. This means that the most musculoskeletal symptom among the visiting housekeepers can be prevented and cured by sufficient physical resting.
