  • Objective: The purpose of this study was to investigate the relationship between physical features, strength, function, and upper extremity musculoskeletal pain during rehabilitation of manual wheelchair users with spinal cord injuries. Design: Cross-sectional study. Methods: The degree and frequency of upper extremity musculoskeletal pain were measured in persons with spinal cord injuries using manual wheelchairs with the use of questionnaires. The pain scores of the hand, wrist, and shoulder joints were calculated by multiplying the seriousness and frequency of pain. We collected data on the manual muscle test, Spinal Cord Independent Measure-III, and the Body Mass Index. Statistical analysis was performed by descriptive analysis and Pearson's correlation analysis. Results: A total of 47 patients participated in this study and the neurological level of the injuries ranged from C2 to S5. Pain in the shoulder joints was the most common in persons with tetraplegia and paraplegia. Pain was experienced as mild to moderate, and occurred one or more times a week. Of the 32 persons with paraplegia, the most common area of complaint was the shoulder. Of the 15 persons with paraplegia, the shoulder joints were the most common site of pain. The independence levels of the persons with spinal cord injuries were highly correlated to muscle strength levels (p<0.05). Conclusions: This study investigated upper extremity musculoskeletal pain during rehabilitation of manual wheelchair users with spinal cord injuries and the relationship between physical features, strength, and function. In most persons with spinal cord injuries, pain and frequency of shoulder joints were high and pain levels were also related to functional levels.

  • Background: Coal mining is a hazardous industry. The purpose of the study is to identify the nature of occupational injuries and diseases among coal miners and to determine the factors that affect the rate of injury and duration of time loss from work. Methods: A retrospective cohort study was conducted using accepted workers' compensation claims data of 30,390 Australian coal miners between July 2003 and June 2017. Results: Musculoskeletal and fracture conditions accounted for approximately 60% of claims in all occupational groups. Cox regression analysis showed that older age and female gender were significant predictors of longer time off work. Injury types and occupations were associated with work time loss: mental health conditions, and machine operators and drivers had significantly longer durations of time off work. Conclusion: Future research can further address how these factors led to longer time off work so that coal industry regulators, employers, and healthcare providers can target interventions more effectively to these at-risk workers.

  • Objectives: Digital infrared thermographic imaging (DITI) has been used widely for various inflammatory diseases, circulatory diseases, skin diseases, musculoskeletal diseases and cancers. In cases of ligament injury, obviously the temperature of the damaged area increases due to local inflammation; however, whether the temperature also increases due to DITI has not been determined. The purpose of the present study was to identify whether or not the changes of temperature in patient's with medial collateral ligament injury were really due to infrared thermography and to determine the applicability of DITI for assessing ligament injuries. Methods: Twenty patient's who underwent DITI for a medial collateral ligament injury from September 2012 to June 2014 were included in the current study. The thermographic images from the patient's knees were divided to cover seven sub-areas: the middle of the patella, and the inferomedial, the inferolateral, the superomedial, the superolateral, the medial, and the lateral regions of patella. The temperatures of the seven regions were measured, and the temperature differences between affected and unaffected regions were analyzed by using the Wilcoxon signed rank test. Results: The 20 patient's were composed of 14 women (70%) and 6 men (30%), with a mean age of $62.15{\pm}15.71$ (mean${\pm}$standard deviation (SD)) years. The temperature of the affected side, which included the middle of the patella, and the inferomedial, the superomedial, the superolateral, and the medial regions, showed a significant increase compared to that of the unaffected side (P < 0.05). The inferolateral and the lateral regions showed no significant changes. Conclusion: Our study results suggest that DITI can show temperature changes if a patient has a ligament injury and that it can be applied in the evaluation of a medial collateral ligament injury.

  • Purpose : The purpose of this study was carried out to review the correlation between foot shape(supination foot, pronation foot) and low back pain, hip abduction muscle and ankle lateral sprain. Methods : By using internet, we research the PubMed, Science Direct, KISS, DBpia We selected the article between 1990 and 2007. Key words were supination foot, pronation foot, balance. Results : Normal control balance of human body needs a optimal anatomical alignment and function of musculoskeletal and central nerve system that control continuously to integrate. Especially ankle and foot complex play an important role in postural control because it is located distal part in human body. Supination foot brings to chronic ankle sprain or chronic ankle instability and range of motion limitation due to the weakness of lateral ankle muscle. Pronation foot brings to knee injury because of lower leg internal rotation force. Conclusion : Excessive supination and pronation foot happen to muscle imbalance. Especially weakness of hip abduction or injury of ankle lateral muscle or low back pain are due to abnormal balance and anatomical alignment.

  • It is widely known that sciatic nerve injury (SNI) can negatively affect the biomechanical characteristics of the musculoskeletal system. However, there were no studies that evaluated and compared denervated side with another side limb at the same time. In this study, sixteen male 12-week-old mice were allocated into two groups: HEMI (Right Sciatic nerve denervated) and CON (Control). Both limbs were scanned using micro-CT at 0 week and 4 weeks. There were significant differences in relative variation (RV) of BMD and all structural parameters compared CON and HEMI in right tibia (p < 0.05). Tb.Th and Tb.Sp distributions were differed CON with HEMI in right tibia. In left tibia, there were significant differences in RV of BMD (p < 0.05) and Tb.Sp distribution. These result means that SNI can induce bone loss in the both side tibiae. However, there was a different profile of bone loss between left and right tibiae.

  • Background: Household waste collectors (HWCs) are exposed to hazardous conditions. This study investigates the patterns of workplace injuries and work-related illnesses of HWCs. Methods: This study uses cases of workplace injuries and work-related illnesses of HWCs that occurred between 2010 and 2011. We analyzed 325 cases of injuries and 36 cases of illnesses according to the workers' age, length of employment, size of workplace, injured part of body, day and month of injury, type of accident, agency of accident, and collection process. Results: There were significant differences in the effect of workers' length of employment, injured part of body, type of accident, agency of accident, and collection process. Results show that most injuries occur in workers in their 50s and older. This study also shows that 51.4% of injuries occur at businesses with 49 employees or fewer. Injuries to waste collectors happen most often when workers are electrocuted after slipping on the ground. The second most prevalent form of injury is falling, which usually happens when workers hang from the rear of the truck during transportation or otherwise slip and fall from the truck. Work-related illnesses amongst waste collectors are mostly musculoskeletal conditions due to damaging postures. Conclusion: These findings will be instructive in devising policies and guidelines for preventing workplace injuries and work-related illnesses of HWCs.

  • 본 논문에서는 근골격계질환, 특히 직업성요통에 관련되는 위험요인의 영향을 종합적으로 살펴보고자 하였다. 첫째로 물리적인 요인의 영향을 알아보기 위하여 해석적인 인체역학 모델과 NIOSH(National Institute for Occupational Safety & Health) Guidelines를 이용하여 자동차 조립작업의 직업성 요통관련 위험도를 평가하였다. 총 246 작업자에 대한 분석을 수행하였는데, 분석결과 총 20개의 작업에서 L5/S1에서의 압축력이 300kg이 넘었으며 44개의 작업은 NIOSH Guidelines에 의한 분석결과, 최저허용기준치(ACTION LIMIT)을 넘는 것으로 나타났다. 둘째로 사회심리적 요인과 직업성요통의 관계에 대해 분석하였다. 사회심리적 요인의 영향을 알아보기 위하여 증상과 PWI(Psychosocial Well-being Index)를 토대로 한 설문을 이용하여 246명 작업자 모두에게 설문조사를 실시하였다. 그 결과 207명의 작업자가 직업성 요통증상을 경험한 적이 있으며 특히 27명의 작업자는 유병자로 분류된 바 있는 사람들이었다. PWI 점수를 근거로 하여 나눈 두 집단(저스트레스군, 고 스트레스군)은 증상이나 진단결과에 있어서 통계적으로 유의한 차이를 보이지 않았다. 또한 사회심리적 스트레스와 작업강도와의 관계를 살펴보면 주로 작업자세요인과 사회심리적 스트레스가 유의한 관계를 가지는 것으로 나타났다. 마지막으로 직업성요통의 발생에 대하여 경로분석을 수행하였다. 분석결과 인구학적 요인, 사회심리적 요인, 작업특성 요인이 직업성 요통에 직접적으로 영향을 미쳤으며, 개인특성요인 즉, 작업경험, 흡연, 수면시간 등은 직업성요통에 직접적인 영향을 미치는 않은 것으로 나타났다. 그러나 개인특성요인은 직업성 요통에 유의한 영향을 미치는 사회심리적 요인과는 밀접한 관계를 가졌다. 향후 다양한 직종에서의 이와같은 경험적 연구결과가 축적되어 우리나라의 조직문화적 특성을 고려한 직업성 요통에 대한 위험모델에 구축되어야 한다고 사료된다.

  • Purpose: The purpose of this study is to examine the effects of proprioceptive neuromuscular facilitation (PNF) exercises on the neck disability index and deep neck flexor endurance of acute whiplash injury patients and to provide basic data for PNF exercises for musculoskeletal system disorder patients. Methods: Twenty acute whiplash injury patients were randomly assigned to an experimental group (n=10) and were treated with PNF exercises whereas a control group (n=10) underwent general exercises. Each session lasted 15 minutes and was performed five times a week for two weeks. The degree of pain was assessed using a visual analogue scale (VAS) and the degree of neck disability was measured by the neck disability index (NDI). Craniocervical flexor endurance (CCFE) tests were conducted to measure deep neck flexor endurance. Results: In terms of the intragroup changes in VAS, NDI, and CCFE, there were significant decreases in both the experimental and the control groups. After intervention, there were significant differences between the experimental group and the control group in terms of intergroup changes in VAS, NDI and CCFE. Conclusion: Although the exercises that are generally applied to acute whiplash injury patients are effective on the whole, PNF exercises are considered to be beneficial, given the improvements in the neck disability index and deep neck flexor endurance.

  • Objectives : The aim of this survey was to investigate the general characteristics of sports injury patients in Korean medical institutions by Korean Medicine Doctors (KMDs) and the treatment patterns of Korean medicine for ankle sprain which is one of the common sports injuries. Methods : An online survey was conducted on KMDs interested in sports injuries to assess their experience and perception of sports injuries including diagnosis, intervention, and treatment plan for ankle sprain. Results : A total of 276 KMDs participated in the survey. They answered that 12% (median, range 0~80%) of patients visiting a Korean medical institution had sports injuries. Sports injuries frequently occur in the ankle, back, shoulder, knee, and elbow and the most common sports injury was sprain/strain. Many participants were aware that sports injuries should be treated differently from other musculoskeletal diseases in general. They reported that confirmation of fracture, swelling, and tenderness was essential to diagnose ankle sprains. Acupuncture was the most commonly used treatment and reported to need 2 to 6 weeks of treatment period, depending on the severity. Conclusions : Based on the findings regarding treatment of sports injury patients by KMDs, this study would be utilized as basic information for pragmatic clinical research design related to sports medicine in the future.

  • Recently, work-related musculoskeletal disorders(WMSDs) have rapidly increased and have been a major issue in the field of industrial safety. Of several physical risk factors for WMSDs, which include postures, vibration, repetitive work, speed or acceleration of movements, etc., awkward postures have been known as one of the major causes of WMSDs. For reducing the potential for injury as a result of postures, cost effective quantification of the magnitude for physical exposure to poor working postures is important and needed. To do this, several postural classification schemes have been developed and used in industrial sites. It is known that perceived discomfort for joint motions and muscle strength for females were much less than those for males. However, the existing postural classification schemes were developed without considering these gender effects. This study aims to develop a new postural classification scheme for female workers, based on the perceived discomfort for joint motions. The result showed that there was significant difference between the schemes for female and male. It was also found that when compared with OWAS, RULA and REBA, postural load was quantified more precisely with the developed scheme. It is recommended that different schemes according to gender of workers involved in work be used in order to accurately evaluate postural load of work postures.
