SBU Assessment

Presents a comprehensive, systematic assessment of available scientific evidence for effects on health, social welfare or disability. Full assessments include economic, social and ethical impact analyses. Assessment teams include professional practitioners and academics. Before publication the report is reviewed by external experts, and scientific conclusions approved by the SBU Board of Directors.

Introduction

This systematic review is a sequel to the report “Occupational exposures and neck and upper extremity disorder” published by SBU in 2012. The term complaint is used as a general description of all symptoms in a region and comprises pain, discomfort, and specific diseases.

Conclusions

This systematic literature review has uncovered a substantial body of evidence that supports an increased risk of complaints of neck, shoulder, arm, or hand are associated with a variety of occupational exposures. Conclusions are not formulated for the results evaluated as having a very low certainty of evidence. No results were evaluated as having a high certainty of evidence. The review evaluates longitudinal studies on the association between exposures in the workplace and complaints but cannot give a definite answer to whether occupational exposure is the only contributing factor to these complaints.

People with the following occupational exposures more often develop complaints of neck or neck/shoulders than people who are not subjected to the specified exposure to the same degree:

  • working with the neck bent forwards or backwards (moderate certainty)
  • working with arms elevated (low certainty)
  • working with repetitive arm movements (low certainty)
  • experiencing high quantitative demands (low certainty)
  • experiencing an imbalance between efforts and rewards (low certainty)

People with the following occupational exposures more often develop complaints of shoulders or impingement than people who are not subjected to the specified exposure to the same degree:

  • doing heavy lifting and forceful work with neck and/or shoulders (moderate certainty)
  • working with arms elevated (moderate certainty)
  • working with repetitive arm movements (moderate certainty for shoulder complaints and low certainty for impingement)

People with the following occupational exposures more often develop complaints of arms and/or forearms than people who are not subjected to the specified exposure to the same degree:

  • doing heavy lifting and forceful work with neck and/or shoulders (moderate certainty)
  • doing forceful work with wrist and/or hand (low certainty)
  • working with repetitive arm movements (low certainty)

People exposed to forceful work with neck and/or shoulders more often develop ulnar nerve entrapment than people who are not subjected to the specified exposure to the same degree.

People with the following occupational exposures more often develop complaints of wrists and/or hands than people who are not subjected to the specified exposure to the same degree:

  • doing forceful work with wrists and/or hands (moderate certainty)
  • doing forceful work combined with repetitive movements with hands (moderate certainty)
  • working with wrists in a bent or twisted position (low certainty)
  • working with repetitive wrist and/or hand movements (low certainty)
  • experiencing high job strain, that is a situation where one experiences high job demands combined with low control or decision latitude at work (low certainty)

People with the following occupational exposures more often develop carpal tunnel syndrome than people who are not subjected to the specified exposure to the same degree:

  • doing forceful work with wrist and/or hand (moderate certainty)
  • doing forceful work combined with repetitive movements with hands (moderate certainty)

Results regarding differences between men and women were inconclusive, so this report cannot conclude if women and men with similar occupational exposures develop complaints of neck, shoulders, arms, or hands to a different extent.

Background and Aim

The objective of this systematic review is to assess the scientific evidence describing the influence of occupational exposures on the development of complaints in the neck, shoulders, arms, or hands. A wide range of occupational exposures were investigated, for example, physical workload, and psychosocial and organisational factors.

Review questions

  1. Is there an association between exposures in the workplace and complaints of neck, shoulders, arms, or hands?
  2. To what extent do these associations differ between women and men?

Inclusion criteria

The inclusion criteria were structured according to PEOS (Population, Exposure, Outcome, and Study design).

PEO

Population: Workers in various occupations.

Exposure: Exposures in the workplace. Exposures only assessed by job title, and vibration exposures were excluded.

Outcome: Complaints of neck, shoulders, arms, or hands. Indirect assessments of complaints, such as sick leave, were excluded.

Study design: Prospective and retrospective cohort studies and case-control studies.

Language: English, Swedish, Norwegian, or Danish.

Search period: From 2010 to 2021. Final search august, 2021.

Databases searched: Embase via Elsevier, Ovid MEDLINE, PsycInfo via EBSCO, and Scopus via Elsevier.

Client/patient involvement: No

Method

A systematic review was undertaken following the PRISMA statement and standard methods used by SBU adapted to the context of occupational exposures. Studies that fulfilled the inclusion criteria were assessed for risk of bias by two experts independently, using pre-set protocols. After conducting independent assessments, the two experts had to agree on a mutual relevance and risk of bias classification. Only studies with low or moderate risk of bias were included in the assessment. The certainty of evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

Results

A total of 19 451 abstracts were identified by the literature search (see Flow chart), 908 were read in full-text and 133 studies were eligible. Sixtyfive longitudinal or case-control studies were considered to have a low or moderate risk of bias and were included in the analyses.
