Introduction: Musculoskeletal disorders (MSD) according to the National Institute for Occupational Safety and Health (NIOSH), are pathologies that compromise the nerves, tendons, muscles and other anatomical structures that provide support to the body. In Colombia, according to the 2002 occupational disease report and other studies, MSDs are reported as one of the main causes of morbidity in workers, work absenteeism and decreased productivity. The National Research Council states that the risk factors are biomechanical and psychosocial; becoming conditions of multifactorial origin. Biomechanical risk factors include exposure to excessive force, awkward postures, repetitive movements of the upper limb, exposure to vibration, among others, and within the associated psychosocial factors, long working hours, work tension, inadequate remuneration and lack of active breaks, among others. Objective: To characterize the biomechanical, psycho-labor demand and the presence of symptoms secondary to MSD of the upper limb in the administrative and general services staff of a Colombian company. Methodology: An observational, descriptive and cross-sectional study was carried out. The sample consists of 139 employees from the administrative and general services area. The variables studied were: age, sex, body mass index, city of work, type of employment, length of service, degree of biomechanical risk, perception of pain or discomfort, loss of strength, tingling or numbness, psychological demands, control about work, insecurity about the future, social support and leadership quality, double presence and esteem. The instruments used were the Nordic Kuorinka questionnaire, the ISO 11228-3:2007 Checklist and the Copenhagen Checklist. For the statistical analysis, the SPSS STATICS software was used, description of variables in percentages, absolute frequencies, measures of central tendency and dispersion. Results: 108 workers who worked in the administrative and general services area participated, most of them female (61%) between 40 and 49 years old. 53.1% of workers have inadequate BMI (overweight and obesity grade I), 50% have more than 5 years of seniority in the position with more than 8 hours of work in 61.1% of workers. The prevalence of musculoskeletal symptoms in the administrative area was higher for pain (48.9%), followed by (26.6%) loss of strength and (31.1%) tingling, predominantly in the wrist. Workers are in a higher percentage exposed to psychosocial factors that represent a risk to their well-being. In 4 of the 6 dimensions evaluated, unfavorable psychosocial conditions were present: psychosocial work demands (45.9%), job insecurity (59.2%), double presence (40.8%) and esteem (70.4%). The most prevalent biomechanical risk was repetitive movements 75% (administrative area and 80% general services) followed by inappropriate postures (64.4% and 75% respectively). Conclusions: Workers in the administrative and general services areas of the company are exposed to risk factors of a biomechanical and psycho-labor type and show osteo-muscular symptoms of the upper limb. The findings of this study are a first approach to a reality of the workers and allow us to see a general panorama regarding the biomechanical, psycho-labor demand and the presence of symptoms secondary to MSD.
