Summary

ABSTRACT Work-related musculoskeletal disorders are seen as a public health problem, and can often lead to temporary or permanent incapacity to work. Exercises can be indicated to prevent musculoskeletal disorders, allied to ergonomic intervention as a preventive approach. Objectives: The objective of this study is to analyze the effects of workplace muscle strengthening kinesiotherapy in the reduction of pain and discomfort in the upper limbs and cervical region perceived by the workers of a university hospital. Methods: After a priori sample size calculation based on pain numeric scale, 166 volunterrs will be recruted and assigned randomly to the "labor kinesiotherapy" group (GCL) or to the "control group" (CG), considering 10% sample size lost and intention to treat. The primary outcomes will be the pain perceived by the Numerical Pain Scale (NDT) and Nordic Questionnaire, and isokinetic muscle strength through the mean peak torque work of shoulder abduction. The discomfort and disability will be evaluated by the PSFS and QuickDASH questionnaires. The Ergonomic Analysis of Work will be evaluated by the manual "Ergonomic Analysis Focused on Activities" - EAFA and application of QEC, RULA, REBA and HARM tools. Statistical analysis will be performed through PASW Statistics ™, version 20.0. The independent sample T test will be used to compare the groups. The Cohen index will be set for the effect size calculation. All analyzes will be conducted with 95% confidence interval and p \<0.05 significance.

Conditions

• Upper Limb; Injury, Superficial, Multiple

Interventions

Type	Name	Description
OTHER	Labor Kinesiotherapy	The intervention group will perform 5 minutes of warm-up with free active exercises, 10 minutes of specific resistance exercises for the cervical and upper limbs and 5 minutes of stretching and muscle relaxation.The initial free active exercises will be performed in 3 sets of 15 repetitions; Resistance exercises will be performed in 3 sets of 10 repetitions and stretching will be performed in 3 sets of 30 seconds. Regarding the intervals between exercises, active recovery will be adopted to counteract the effects of muscle fatigue.
