Exercise at Workplace for Manual Material Handling Workers
Exercise at Workplace for Manual Material Handling Workers
This study aim to evaluate the effectiveness of exercise at workplace for manual material
 handling workers. This is a randomized control trial study by cluster with three parallel
 groups (n=200). Participants will be randomized in three groups: (1) control group - will be
 receive ergonomics orientation . (2) Intervention group - exercise at workplace four times
 per week, during 15 minutes; (3) Intervention group 2 - exercise at workplace three times per
 week, during 15 minutes.Outcomes: The outcome measure will be verified in three moments at
 baseline, in six and eleven months of the intervention. The primary outcome is pain,
 electromyography. Secondary outcome is palmar dynamometer, BMI, physical activity level.
Objective: This study aim to evaluate the effectiveness of exercise at workplace for control
 and prevention nonspecific low back pain. Methods: This is a randomized control trial study
 by cluster with three parallel groups. The context of this study is a motorcycle parts
 company importer localized in several states (Piaui, Ceará e Maranhão). The company has 575
 workers, being 240 manual material handling. All are men over 18 years old that perform goods
 shipment (each work develop one this tasks - stock, separation, conference and packaging).

 The inclusion criterial are workers that perform manual material handling for at least six
 months and signing informed consent form. The exclusion criterial were sick leave. The
 workers will be included with low back pain or no low back pain (at baseline). All will be
 interviewed to obtain: weight, height, BMI, age, marital status, educational level, and
 actual function (stock, separation, conference and packaging sick leave (the last 12 months),
 musculoskeletal complains, medications, complementary exams, surgery and or fractures.
 Participants will be randomized in three groups: (1) control group - will be receive
 orientation about manual material handling, postural and low back care (lecture and
 guidance). The training will be instructions according Ergonomics standard (NR17) about
 transportation and load handling and exercise in workout. (2) Intervention group 1 - will
 receive the same instruction of the control group, and will perform exercise at workplace
 four times per week, during 15 minutes; (3) Intervention group 2 - will be receive the same
 instruction of the control group, and will perform exercise at workplace three times per
 week, during 15 minutes. Outcomes: The outcome measure will be verified in three moments at
 baseline, six and eleven months of the intervention. The primary outcome is pain,
 electromyography. Secondary outcome is palmar dynamometer, BMI, exercise workout.

 Expected Results: The manual material handling workers will be better after intervention by
 exercise at workplace. The effectiveness of exercise for low back pain and no low back pain
 groups will be contribute to change the behavior in occupational context.
Inclusion Criteria:

 -  The inclusion criterial are workers that perform manual material handling for at least
 six months and signing informed consent form.

 Exclusion Criteria:
