Not Applicable

Completed

• Conditions: Upper Limb; Injury, Superficial, Multiple
• Interventions: Other: Labor Kinesiotherapy

• Registration Number: NCT04047056
• Lead Sponsor: University of Sao Paulo

Brief 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.

Arm && Interventions

Group	Intervention	Description
Ergonomic Guidelines Manual	Labor Kinesiotherapy	A manual of ergonomic occupational and daily living guidelines will be given to both control and labor kinesiotherapy groups, which is the only approach for the control group initially.
Labor Kinesiotherapy in group	Labor Kinesiotherapy	The intervention will be performed by a physical therapist, which will consist of preparatory labor kinesiotherapy, which aims to prepare the workers' osteo-articular system for the beginning of the work activity, acting more specifically on those muscle groups that will be most required during the journey which will be identified in the evaluation. Labor kinesiotherapy will be performed in the workplace before the workday and will last 20 minutes, 3 times a week, for 12 weeks.

Primary Outcome Measures

Name	Time	Method
Numerical Pain Scale - NPS	12 weeks.	Difference in numerical pain scale in the 3 evaluations. The numerical pain scale score ranges from 0 to 10, with values closer to 10 indicating worse pain.
shoulder abduction Torque peak in the Isokinetic Dynamometer	12 weeks.	Mean difference in torque peak achieved by the Isokinetic Dynamometer at baseline and after 12 weeks.

Secondary Outcome Measures

Name	Time	Method
Quick Disabilities of de Arm, Shoulder and Hand (QuickDAS)	12 weeks.	Difference in DASH questionnaire scores in 3 evaluations. The QuickDASH score ranges from 0 to 100, with values closer to 100 indicating better health.
Patient Specific Functional Scale (PSFS)	12 weeks.	Difference in PSFS questionnaire scores in 3 evaluations. The PSFS allows patients to report on their functional status at baseline and at a follow-up session, to determine if a meaningful change in functional status has occurred.
