Incidence Of Musculoskeletal Complaints Research Articles

Upcoming Paralympic summer games in Rio: what did the German medical team learn from the London Games?

Musculoskeletal complaints are frequently diagnosed in Paralympic athletes. Despite the increased professionalism in Paralympic Sports, the documentation of injuries and other health complaints during high-level competition is sparse. With respect to the upcoming Paralympic Summer Games in Rio de Janeiro, the aim of this study was the analysis of all musculoskeletal complaints within the German Paralympic Athletes during the London 2012 Paralympic Games. All musculoskeletal complaints (MSC) of the 150 German athletes seeking medical attention, hereby defined as "injury", were recorded during the in-competition period of the London Paralympics Games (22 days), regardless of their severity and consequences. Standardized documentation included the onset of symptoms, the medical diagnoses, the therapeutic measures taken as well as consecutive restrictions in training and competition. Incidence rates and localizations were analyzed by sports discipline. A total of 201 musculoskeletal complaints were recorded for 140 athletes (93.3%), corresponding to 1.4 musculoskeletal complaints per "injured" athlete. The incidence of musculoskeletal complaints in German athletes was 62.9±15.4/1000 athlete-days. High incidence rates (IR) were observed in wheelchair basketball (IR 72/1000 athlete-days, 1.6 injuries per athlete) and equestrian events (IR 72.7, 1.6). Musculoskeletal complaints were mainly located in the upper extremities (37.6%) and the spine (37.6%). The most frequent diagnoses were myalgia (N.=105, 52%). We noted a high rate of musculoskeletal complaints among German Paralympic athletes across sports and body parts, highlighting the need for prevention programs that focus on the upper extremities and spine.

Musculoskeletal complaints among central sterile supply technicians in relation to physical and psychosocial factors at work

Objective: The objective was to examine the prevalence of musculoskeletal complaints (MSCs) among central sterile supply technicians (CSSTs) in relation to their physical workload and psychosocial factors at work. Material and Methods: A cross-sectional study was conducted in 2013 among 64 CSSTs working in the central sterile supply department of a tertiary care hospital in Saudi Arabia. A questionnaire was used to collect data on demographic characteristics, physical workload, and psychosocial factors at work. Furthermore, a Nordic Questionnaire was used to examine the prevalence of MSCs among the participants. Results: The study showed that the overall 1-year prevalence of MSCs at anybody site of the participants was 43.8%. The reported MSCs were mostly related to the low back (28.1%), followed by wrists/hands (23.4%) and shoulders (21.9%). Age, gender, and BMI were not associated with MSCs. Work requiring exertion of arms/hands, and working in awkward postures were the only physical work factors that were significantly (P < 0.05) higher among CSSTs who had MSCs (89.3%, 57.1%, respectively) compared to CSSTs who had not (69.4%, 30.6%, respectively). Psychosocial factors at work did not show a significant difference between CSSTs who had MSCs and those who had not. Conclusion: 43.8% of the CSSTs reported 1-year prevalence of MSCs affecting mostly low back, wrists/hands, and shoulders. Ergonomic assessment and preventive intervention should be conducted to prevent the incidence of MSCs among CSSTs through controlling both physical and psychosocial risk factors at their workplace.

Genetic polymorphism at Val80 (rs700518) of the CYP19A1 gene is associated with aromatase inhibitor associated bone loss in women with ER (+) breast cancer

PurposePolymorphisms in the CYP19A1 (aromatase) gene have been reported to influence disease-free survival and the incidence of musculoskeletal complaints in patients taking aromatase inhibitors (AIs) for estrogen receptor positive (ER+) breast cancer. Bone loss and fractures are well-recognized complications from AI therapy. The objective of this study is to determine the influence of polymorphisms in the CYP19A1 gene on bone loss among patients taking aromatase inhibitors for ER+ breast cancer. Patients and methodsThe subjects consisted of 97 postmenopausal women with ER+ breast cancer who were initiated on third-generation AIs. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry at baseline and at 6 and 12months. Twenty-four hour urine N-telopeptide (NTX) was measured by Elisa and serum estradiol was measured by ultrasensitive radioimmunoassay at baseline, and at 6months. Genotyping was done by Taqman SNP allelic discrimination assay. ResultsWomen with the AA genotype for the rs700518 (G/A at Val80) developed significant bone loss at the lumbar spine and the total hip at 12months relative to patients carrying the G allele (GA/GG); both p=0.03. There was a borderline greater increase in urinary NTX in those with the AA genotype compared to patients with the G allele, p=0.05; but no significant difference in changes in estradiol levels among the genotypes. ConclusionPatients with the AA genotype for the rs700518 polymorphism in the CYP19A1 gene are at risk for AI-associated bone loss and deserve close follow-up during long-term AI therapy.

Mental Health Levels and Incidence of Musculoskeletal Complaints among Speed Boat Crew Members

BackgroundThe occupational health is an important issue. In some jobs, the working conditions contribute to musculoskeletal complaints and the overall health of the individual is compromised. Musculoskeletal complaints have gained credence in the public as one of the most important problems in the field of occupational diseases. Physical and mental health of crew members with critical jobs and stressful environments must be considered as well.ObjectivesThis study performed an assessment on levels of mental health and the correlation with the frequency of accompanying musculoskeletal complaints (such as neck, back and knee pain) of crew members of speed boats.Material and Methods149 onboard crew members of speed boats were recruited in a descriptive-correlation study by nonrandom sampling using conducted GHQ12, NMQ and demographic questionnaires.ResultsAlthough 63.8% (95 people) had what is conventionally defined as normal mental health, 36.2% (54 cases) had an inherent mental health condition. Overall, 61.1% (91 cases) suffered from back pain, 60.4% (90 cases) complained of knee pain, and 40.3% (60 patients) complained of neck pain. The combination of knee and back pain (48.3%) were the most common complaints whereas the combination of neck and knee pain (31.5%) were the least frequent; 28.2% complained of pain in all three areas. Interestingly, there was correlation between the presence of musculoskeletal complaints and less than optimum mental health.ConclusionsDue to the high number of musculoskeletal complaints and the compromised mental health conditions among one-third of the onboard crew members of speed boats, attention for maintaining and improving the health of these members must be considered.

The Prevalence of Computer-Related Musculoskeletal Pain Among College Students-a Cross-Sectional Study

Problem statement: In the recent years, there has been an increase in incidence of musculoskeletal complaints among college students. Potential risk factors for this might be increased use of computers. The purpose of this study was to examine among college students (a) the prevalence of musculoskeletal pain and (b) the association of musculoskeletal pain with computer use and physical activity performed during last one week. Approach: A cross-sectional study was performed among college students aged 19-27 years in the first through third years of their college study. Using random sampling, two surveys, the Boston University Computer and Health Survey and the International Physical Activity Questionnaire with informed consent were distributed to 200 college students. Out of 178 surveys returned, 170 surveys were found to be acceptable. Results: About 88% (149/170) of the respondents reported musculoskeletal complaints in the two weeks prior to completing the survey. The prevalence of musculoskeletal pain was higher in female 90% than in male students 76%. Although there was no statistically significant association between the type of computer and musculoskeletal pain, the prevalence of musculoskeletal pain was higher for students using laptop ( 90% ) when compared to those using both desktop and laptop and desktop only (87 and 86%) respectively. There was no statistically significant correlation for musculoskeletal pain with hours of computer use per day, type of computer used and level of physical activity. Conclusion: This study strengthens the findings that musculoskeletal pain is common among college students but it is not influenced by computer use and level of physical activity. Future research should continue on larger students’ sample to better understand the musculoskeletal complaints, physical activity and computer use and to find whether these factors are related.

The prevalence and incidence of musculoskeletal symptoms among hospital physicians: a systematic review

ObjectivePhysicians are exposed to a range of work-related risk factors that may result in occupational diseases. This systematic review aims at shedding light on the prevalence and incidence of musculoskeletal complaints among hospital physicians.MethodsA systematic literature search was performed in Pubmed and EMBASE (1990–2010), and methodological quality criteria were applied. A search was done for musculoskeletal complaints.ResultsFive medium-quality studies and three high-quality studies were included in this review. The definitions and assessment used in the studies for musculoskeletal complaints were different. In short, the frequently reported prevalence for hand and wrist pain was 8–33 and 0%, 17% for shoulder pain, and 9–28% for neck pain. Moreover, the annual prevalence of low back pain was between 33 and 68%.InterpretationThe limited number of studies makes it difficult to draw conclusions, and the results should be intepreted with care. In conclusion, musculoskeletal complaints may be work-related complaints in hospital physicians, which need future attention.

Associations between hand–wrist musculoskeletal and sensorineural complaints and biomechanical and vibration work constraints

A 3-year prospective epidemiological study was conducted to investigate the relationship between musculoskeletal complaints (MS) and sensorineural complaints (SN) of the workers in the hand–wrist region. A group of 69 workers (G1) using vibrating tools in eight different working situations was compared to a group of 62 workers (G2) performing heavy work without vibration and 46 workers (G3) performing light work without vibration. Biomechanical constraints (force, postures, repetitiveness and movement velocities) were analysed for each working situation and the vibration exposure at the eight workplaces with the 69 workers. MS and SN data were collected using the nordic questionnaire, modified to collect information about the frequency intensity and duration of complaints. The prevalence of complaints at the start of the study was significantly greater for G1 (72.5%) than for G2 (56.5%), itself greater than for G3 (30.4%). The prevalence of SN was about 40% for G1 and 2.5 times smaller in the two other groups. During the two years follow-up, new cases of ‘serious’ MS and SN developed. The annual incidence was respectively 8.3 and 5.4% on average. The incidence of MS was slightly but not statistically significantly greater for G1, while the incidence of SN was statistically higher (P<0.01) for G1 (10.9%) than for the two other groups (4.1 and 2.1%). Forces and angular repetitiveness were the only biomechanical factors significantly greater for G1. The vibration exposure duration of the G1 workers varied, in average, from 10 to 70% of the work time and the weighted personal exposure amplitude (AEPw) varied from 0.5 to 25.4 ms−2. The probabilities of complaints at the beginning of the study (cross-sectional study) were estimated using multiple logistic regression models. The prevalence odds ratio (POR) for MS was equal to 4 for G1 compared to G2 and equal to 9 compared to G3. Force and vibration exposure were the main constraint parameters associated with this likelihood. As far as the SN are concerned, G2 and G3 were not statistically different, but the POR for the G1 workers was 4.5 compared to both groups. The most significant constraint factor was the weighted personal exposure acceleration. The same procedure was used to estimate the likelihood of development of ‘serious’ complaints (longitudinal study). The three groups did not appear significantly different concerning the ‘serious’ MS, while the incidence odds ratio (IOR) of ‘serious’ SN was very high (28.5) and significantly greater for G1 than for the two other groups. The likelihood of development of ‘serious’ SN increased with AEPw. According to this prediction model, the risk of ‘serious’ SN would be about 6% at the proposed European ‘action’ value (2.5 ms−2) and about 10% at the ‘limit’ value (5 ms−2).
