Implementation of Physical Exercise at the Workplace (IRMA09) - Laboratory Technicians (IRMA)

September 1, 2015 updated by: Lars L. Andersen, National Research Centre for the Working Environment, Denmark
Musculoskeletal disorders and stress of employees remain a major problem in many occupations. The aim of this study is to investigate the effect of an individually tailored bio-psycho-social intervention strategy versus "usual care" ergonomics and standard physical exercises (reference group) on musculoskeletal pain, work disability, and stress in lab technicians with a history of work-related musculoskeletal pain.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain intensity
Time Frame: change from baseline to week 10
The change in "pain intensity during the last week" (average value of back, neck, shoulder, elbow and hand) from baseline to 10 week follow-up between the individually tailored biopsychosocial group and reference group. 2-way analysis of variance with repeated measures will be used, with time, group and time x group as fixed factors and subject as random factor. Analyses will be controlled for pain intensity at baseline.
change from baseline to week 10

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Stress
Time Frame: change from baseline to week 10
Cohens perceived stress scale
change from baseline to week 10

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
WAI
Time Frame: change from baseline to week 10
Work ability index questionnaire
change from baseline to week 10
Fear Avoidance
Time Frame: change from baseline to week 10
Fear avoidance is evaluated by the Fear Avoidance Beliefs questionnaire (FABQ) by Waddell et al. at baseline and follow-up. Briefly, the FABQ is a two-part questionnaire. The first part consists of five questions/statements about pain and physical activity and the second part consists of 11 questions/statements about how work affects the participants' perception of pain. Each question is scored from 0-5 ranging from completely disagree (0) to completely agree (5).
change from baseline to week 10
Muscle function
Time Frame: change from baseline to week 10
Muscle strength, function and tenderness of the shoulder, arm, wrist/hand is assessed by maximal isometric voluntary contractions in a custom-built dynamometer (Bofors Elektronik, Karlskoga, Sweden) setting and by pressure-pain threshold testing (PPT). Also rate of force development (RFD), force steadiness (FS), force precision (FP) and fatigue (F) are measured by using custom-made MATLAB programs. The strength tests are a part of an extensive physical examination by trained (and blinded) medical professionals at baseline and follow-up. Muscle activation level is measured by surface electromyography (EMG) (Nexus Mark 10, Mindmedia, Netherlands) on the forearm extensors, shoulder external rotator (Infraspinatus Mm.) and descending part of the trapezius muscle. Further, surface EEG (Nexus Mark 10, Mindmedia, Netherlands) will measure global brain activity during pre- and post testing by using a single a single sensor placement on the forehead (Fpz).
