Objective:

to stablish the relationship between the level of knowledge on ergonomic risk and symptoms of musculoskeletal disorders (MSDs) in health personnel.

Material and Methods:

a descriptive, correlational, cross-sectional and correlational study during 2017-2018 in a hospital of Yurimaguas, Perú, in a convenience sample of 133 workers surveyed according to selection criteria.

Results:

the mean age was 39.74±7.33, 66.2% were nursing technicians; 67.7% were female and 10 ± 6.14 years of work experience. Medium level of knowledge was registered in 57.9% and low in 27.1%; 51.9% had symptoms, 100% had pain, 92.7% in low back and mostly at the end of the workday and between 3 and 6 months. There was a highly significant difference between level of knowledge and symptoms (X2=38.17; p=0.000), specifically low level (p=0.000); nursing technician and ≤5 years work experience time also showed significant difference with symptoms.

Conclusions:

the knowledge was related to the symptoms of MSDs. It is suggested to improve it, also considering the instruments used, adequate training and research according to the type of worker.
