Introduction: Musculoskeletal complaints have been observed in the recovery phase of patients with moderate-to-severe coronavirus disease 2019 (COVID-19). We noted several referrals for physical rehabilitation at the University of the Philippines-Philippine General Hospital (UP-PGH), a designated COVID-19 referral center. These observations resembled the musculoskeletal manifestations associated with poorer outcomes reported in other coronavirus studies. Objectives: The study determined the musculoskeletal signs and symptoms of adults in the recovery phase of moderate to severe COVID-19 using the COVID Musculoskeletal Assessment Tool (CMAT). Methods: This was a three-phased, prospective, descriptive study of adults admitted for COVID-19 at the UP-PGH. Phase 1 was the development of the CMAT based on a review of related literature and patient charts, and patient interviews. The tool was pretested and validated in Phase 2 before it was used in the evaluation of study participants in Phase 3 of the research. Data was encoded using Microsoft® Excel 2007 and analyzed using STATA, Version 12.0 (Texas, USA). Descriptive statistics were used to summarize the variables collected for the study. Results: A cohort of 40 patients admitted at the UP-PGH for moderate-to-severe COVID-19 infection was evaluated using the CMAT. Most of the patients had an average age of 55 years and were males. Majority resided in an urban area, reached high school education, and were ambulatory before their illness. The most common comorbidities were hypertension and diabetes. All patients required oxygen support. Based on the CMAT, majority of the participants complained of muscle pain, generalized weakness, and easy fatigability. Other common findings were neck-shoulder and lower limb pain, dyspnea on exertion, limited mobility in the trunk, hips, and knees, joint pains, and decreased muscle strength. Half of the participants needed a wheelchair or walker to ambulate. These findings may be due to the COVID-19 disease and to prolonged confinement in bed. Only one patient underwent physical therapy through bedside instructions. Conclusion Musculoskeletal signs and symptoms were common in the patients recovering from COVID-19 disease. The COVID-19 Musculoskeletal Assessment Tool facilitated the evaluation of patients and the recording of results. Early referral for medical rehabilitation and timely intervention are strongly recommended.

PURPOSE: This examined the effect of Kinesio taping pre-intervention on the pain, tenderness, proprioceptive sensation, and muscle strength associated with delayed onset muscle soreness. METHODS: Thirty subjects were divided into a Kinesio taping application group of 15 subjects and a control non-taped group of 15 subjects, and the changes in individual variables were analyzed before taping and at 24, 48, and 72 hours after taping using two-way repeated ANOVA. Post-hoc t-tests were conducted in the cases with intergroup interactions, and the significance level α was set to α=0.01. RESULTS: The changes in pain during rest were significantly different only for the times, while the changes in pain during exercise were significantly different for the times, interactions between the times and groups, and intergroup changes (p<0.05). The changes in tenderness were significantly different for the times and for interactions between the times and groups (p<0.05). The changes in proprioceptive sensation were significantly different for the times, interactions between times and groups, and intergroup changes (p<0.05). The changes in muscle strength were significantly different only for the times (p<0.05). CONCLUSION: The application of Kinesio taping had positive effects on the pain, tenderness, and proprioceptive sensation of delayed onset muscle soreness. These results suggest that Kinesio taping can be a useful therapeutic factor in future studies and in clinical settings.

PURPOSE: The purpose of this study was to investigate muscle pains of emotional laborers and determine whether there were differences in their muscle pains depending on the hours spent on emotional labor. METHODS: This is a secondary analysis of the data collected from the 3rd (2011) Korean Working Conditions Survey. 50,032 participants responded to the study's questionnaire. Among them, 15,669 participants were emotional laborers who directly dealt with people such as customers, passengers, pupils, patients, etc. RESULTS: Thirty three percent of subjects had reported muscle pains. Muscle pains of subjects were positively related to the hours spent on emotional labor (p<.001). According to the logistic regression analysis, the adjusted odd ratio of the subjects who spent about almost all of the work hours on emotional labor was 1.32 (95% CI: 1.15~1.52), compared to the subjects who spent about a quarter of their work hours on emotional labor, when other factors were controlled. CONCLUSION: The study's findings indicate that engaging in emotional labor for longer hours increases the risks of muscle pains. Occupational nurses must pay closer attention to the management of muscle pains of emotional laborers.

BACKGROUND: Subparalyzing doses of nondepolarizing muscle relaxants are often given prior to succinylcholine to reduce the adverse effects of succinylcholine. We designed this study to determine the optimal choice of nondepolarizing muscle relaxants and the optimal interval between pretreatment and succinylcholine administration. METHODS: 240 ASA I or II adult patients were randomized into six groups: groups V1.5 and V3 received 0.015 mg/kg of vecuronium 1.5 min and 3 min before succinylcholine; group R1, R1.5, and R3 received 0.09 mg/kg of rocuronium 1 min, 1.5 min and 3 min before succinylcholine; and group SCC received no pretreatment. In this study, 2 mg/kg of succinylcholine was used. The presence and severity of fasciculations and intubating conditions were evaluated. Myalgia was also recorded on postoperative days 1 and 2. RESULTS: Group R3 was significantly better than other groups in terms of preventing fasciculations, and was followed by groups R1.5, R1, V3, V1.5 and group SCC. Intubating conditions were significantly worse in all pretreated groups than in group SCC, but no significant differences were observed between the pretreated groups. CONCLUSIONS: Succinylcholine-induced fasciculations are effectively prevented by pretreating with rocuronium 3 min or 1.5 min prior to succinylcholine administration. However intubating conditions are worsened by pretreatments.

Since the reservior of leptospires organism is consisted of a broad spectrum of animals, the best method of prevention is vaccination. The clinical trial of leptospires vaccine conducted on human volunteer for its immunogenicity and safety. Summarized results are as follows: 1. The Oral temperature among vaccinated group ranged from 36.7 +/- 0.34 degrees C, while in placebo injected group it ranged from 36.4 +/- 0.46 degrees C to 36.7 +/- 0.53 degrees C. There wan no association between vaccination and fever (p<0.05). 2. Mild local reactions revealed in vacciness were swelling (50-75%), Redness(75-90%), and induration(25-40%). Placebo injected group revealed only redness in 12.5% in the 1st injection and 37.5% in the second injection. The duration local reactions on injection site for both vaccinees and placebo groups disappeared within 48 hours. 3. Generalized Symptoms complained by the vaccinees were myalgia (25%), back pain(15%), headache(15%), pruritus(15%), and abdominal pain(10%), whereas placebo group complained of headache(25%), myalgia(12.5%), back pain(12.5%), pain in eyes(12.5%), abdominal pain(12.5%) prutitus(12.5%) and nausea(12.5%). 4. The serological test(MAT) of vaccinees showed geometric mean antibody titer as follows: a. L. icterohemorrhagiae lai, 1 week after 1st vaccination: 22.45, 1 week after 2nd vaccination: 111.23, 3 week after 2nd vaccination: 266.64, b. L. canicola canicola, 1 week after 1st vaccination: 24.62, 1 week after 2nd vaccination: 123.92, 3 week after 2nd vaccination: 276.55, c. L. icterohemorrhagiae copenhageni, 1 week after 1st vaccination: 28.28, 1 week after 2nd vaccination: 128.55, 3 week after 2nd vaccinaton: 247.88, Whereas all of the placebo injected group, showed below 1 : 20 titers. The sero-conversion rate of vaccinees were 100 percent.

PURPOSE: The purpose of this study was to compare the health status between foreign workers and native workers and to examine the influencing factors of health status of foreign and native workers. METHODS: This was a secondary analysis of the data collected from the 3rd (2011) Korean Working Conditions Survey (KWCS). The sample included 101 foreign workers and 101 native workers matched by age and gender. RESULTS: The difference in health status between foreign workers and native workers was not statistically significant. The most commonly complained health problem of foreign workers was muscle pain of the upper limbs. Among foreign workers, hazard exposure, coworker support and supervisor support were significant predictors of health status. Among native workers, income level and obesity were significant predictors of health status. CONCLUSION: For health management and health promotion of foreign workers, employers and health providers need to establish coworker supporting systems in workplace and improvement strategies of work environment. Particularly, they must pay closer attention to management of foreign workers' musculoskeletal disorder.

We report a case of clinical features corresponding to Eosinophilia-Myalgia syndrome, with no causal relationship with L-tryptophan. Since the epidemic of L-tryptophan associated Eosinoghilia-Myalgia Syndrome in 1989, only 2% of the cases were found not to be related to L-tryptophan in America. We believe that this is the first case report of Eosinophilin-Myalgia Syndrome not related to L-tryptophan in Korea.

The grip strength of both hands in 290 female international telephone operators were measured and the relationships between thd grip strength in the major hand and various variables, such as height, weight, age^ subjective symptoms, muscle tenderness, work duration and house work, were observed. The results were as follows: 1. Grip strength was signficantly higher in the rriapr hand than in ihe minor hand. 2. Significantly tower grip strength in the major hand was noted in the musculoskeletal complainants than En the non-complainants. 3. Grip strength in the major hand was signficantly lower In myalgia subjects than in others. 4. Grip strength in the major hand showed significant negative correlation with 'A' response on questionnaire items and number of tender points. 5. Grip strength in the mapr hand showed significant positive correlation with body weight. 6. According to stepwise multiple regression procedures, three major factors, namely, number of 'A' response on questionnaire items, number of tender points and body weight, explained only less than 7% of total variance of grip strength in the major hand.

BACKGROUND: The study was designed to assess the changes in working conditions through a comparative analysis of the characteristics of working conditions in 2006 and 2010. METHODS: We performed a comparative analysis of the data related to the first Korean Working Conditions Survey (KWCS) and the second KWCS in the categories of demographic characteristics, quality of labor, exposure to hazards, and health problems. RESULTS: From our analysis of the demographic characteristics, we saw an increase in labor force participation rate of women and elderly people. As a result of the investigation with regards to working hours, the ratio of employees who worked for > or = 49 hours per week was decreased and the ratio of employees who worked for > or = 40 h/wk increased. As for exposure to hazards, exposure to tobacco smoke notably decreased in 2010 compared with 2006. With regards to health problems, there was a sharp increase in the number of people who complained of muscle pain in their arms and legs. CONCLUSION: KWCS data included many aspects of working conditions as a nationwide sample. In addition, because this is a periodic nationwide survey, the labor force, working hours, harmful factor exposure, and the change in health problems characteristics according to the flow of time could be investigated. The information comparing the main results of the first survey conducted in 2006 and the second survey conducted in 2010 obtained through this study can be used as an important base material for the establishment of the national policy.
