    What do questionnaires for assessment of physical functioning in neck disorders really measure?: A systematic review of the literature2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Background. In order to determine which interventions are effective in the treatment of musculoskeletal disorders, valid and reliable instruments are required. However, there is a lack of consistency in the use of outcome measures, both in research and in treatment, that makes comparisons difficult or impossible; the content and quality varies widely be-tween questionnaires. This study focuses on the measurements of the physical function-ing of people with MSDs. The aim of this systematic review is to investigate how physical function is measured in people with musculoskeletal disorders or chronic pain. Specifically we want to determine: (1) What instruments are used to measure physical function in people with musculoskeletal disorders or chronic pain? (2) What do those instruments measure? (3) What is the methodological quality of these instruments?

    Method. The study was performed as a systematic literature review in the data bases PubMed, Cinahl, Web of Science, and Scopus, using the same set of keywords and Bool-ean operators. The selection of relevant articles was performed by reviewing the title and abstract first, and the article text thereafter. Selected articles were classified according to the “ICF Classification of Functioning, Disability and Health.” Subsequently, articles will be examined with respect to relevant quality indicators using the “Cosmin checklist.”

    Results. 69 relevant questionnaires were found and were sorted into groups according to focus. As a first step, neck and arm-shoulder-hand questionnaires were analyzed. The ICF-classification revealed that the included items belonged to the components “body func-tions” and “activity/participation,” and the included domains varied significantly between the questionnaires. The quality of the instruments will be determined in the next step.

    Discussion. A review and analysis of this kind makes it possible for researchers and clini-cians to more easily select the most suitable questionnaire for their purpose based on the content and quality of the questionnaire.

    Divergences in descriptions of the internal work environment management, between employees and the management, a case study2013Rapport (Annet vitenskapelig)
    Abstract [en]

    The aim of the case study was to critically compare the descriptions of employees and managers of how the work environment is prioritised in a medium-sized Swedish retailer belonging to an international group. The study is based upon a questionnaire study of employees (n=55), and on interviews with people in leading positions with partial responsibility for the work environment at the company (n=6) as well as with the local safety delegate (n=1). The results show that the driving forces behind the work environment are, according to respondents, finances, legislation, trademarks and the attitudes of the upper management. The on-going work environment management is described differently in terms of its form and content by employees and persons in leading positions.

    Observational Methods for Assessing Ergonomic Risks for Work-Related Musculoskeletal Disorders: A Scoping Review2018Inngår i: Revista Ciencias de la Salud, ISSN 1692-7273, Vol. 16, nr Special Issue, s. 8-38Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Work-related musculoskeletal disorders (wrmsds) are one of the most common causes of absence from work. Exposures in the work environment can cause or aggravate the impact of these musculoskeletal disorders and the identification of ergonomic exposures are essential in risk assessment. It is important to assess all three key indicators of these exposures (intensity, frequency and duration) for being able to estimate the risk level for the development of wrmsds. Aim: This paper aims to give an overview of some of the observational methods that can be used for assessment of ergonomic risks at the workplace. Methods: This study was conducted as a scoping review of the medical and ergonomic literature and official governmental webpages in Sweden, U.S.A. and the Netherlands. Results: In total, 19 different observational methods were identified. We summarize our findings based on the body parts that were studied and what key indicators were assessed: 1) intensity of the work load (posture and force production), 2) frequency of the work load (e.g. repetitive movements), and 3) the duration of the work load (e.g. static work). In an appendix we include a brief presentation of these methods together with the work sheet (if available) and the source reference of the observational method. Conclusion: For ergonomists that perform risk assessments, there is a large number of observational assessment tools available and it is important to understand that different methods can be used simultaneously to be able to estimate the objective risk levels for wrmsds. © 2018, Universidad del Rosario.

    The impact of visually demanding near work on neck/shoulder discomfort and trapezius muscle activity: Laboratory studies2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Introduction: Musculoskeletal discomfort in the neck and shoulders is common among workers performing visually demanding near work, e.g., on a computer screen, and sustained low-level muscle activity during such work can lead to work-related pain. The relationships between visual demands and muscle activity and discomfort in the neck/shoulder region are at present unclear. Aim: The aims of this thesis were to determine whether neck/shoulder discomfort and trapezius muscle activity increases during visually demanding experimental near work, and to investigate whether eye-lens accommodation is a mediating mechanism behind increased trapezius muscle activity. Methods: The four papers included are based on two experiments with different visually demanding near work tasks (duration 5 and 7 min). Trial lenses of different diopters were used to manipulate the visual demands (i.e., induce more or less accommodation) and thereby create different viewing conditions. Monocular viewing, which does not require active convergence, was used to examine the isolated effect of accommodation. Eye-lens accommodation and trapezius muscle activity were measured continuously during the visual tasks, and in one experiment the participants rated their eye and neck/shoulder discomfort at baseline and after each visual task. Results: Neck/shoulder discomfort and trapezius muscle activity increased during the visually demanding near work and participants experiencing a greater increase in eye discomfort (compared with baseline) also developed more neck/shoulder discomfort with time. There were no significant differences in muscle activity among the viewing conditions, and no effect of isolated accommodation response within the monocular viewing conditions. Conclusion: These findings indicate that accommodation per se is unlikely to mediate trapezius muscle activity. Instead, the increase in trapezius muscle activity observed here may be due to a combination of high visual attention and enhanced requirement for eye-neck (head) stabilisation. Since these results suggest that neck/shoulder discomfort may aggravate with time when the visual demands are high, it is important to provide good visual conditions in connection with visually demanding occupations.

    Effects of visually demanding near work on trapezius muscle activity2013Inngår i: Journal of Electromyography & Kinesiology, ISSN 1050-6411, E-ISSN 1873-5711, Vol. 23, nr 5, s. 1190-1198Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Poor visual ergonomics is associated with visual and neck/shoulder discomfort, but the relation between visual demands and neck/shoulder muscle activity is unclear. The aims of this study were to investigate whether trapezius muscle activity was affected by: (i) eye-lens accommodation; (ii) incongruence between accommodation and convergence; and (iii) presence of neck/shoulder discomfort. Sixty-six participants (33 controls and 33 with neck pain) performed visually demanding near work under four different trial-lens conditions. Results showed that eye-lens accommodation per se did not affect trapezius muscle activity significantly. However, when incongruence between accommodation and convergence was present, a significant positive relationship between eye-lens accommodation and trapezius muscle activity was found. There were no significant group-differences. It was concluded that incongruence between accommodation and convergence is an important factor in the relation between visually demanding near work and trapezius muscle activity. The relatively low demands on accommodation and convergence in the present study imply that visually demanding near work may contribute to increased muscle activity, and over time to the development of near work related neck/shoulder discomfort.

    Neck/shoulder discomfort due to visually demanding near work is influenced by previous neck pain, task duration, astigmatism, eye discomfort and accommodation2017Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 8, artikkel-id e0182439Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Visually demanding near work can cause eye discomfort, and eye and neck/shoulder discomfort during, e.g., computer work are associated. Here, to investigate direct effects of experimental near work on eye and neck/shoulder discomfort, 33 individuals with chronic neck pain and 33 healthy control subjects performed four visual tasks, rating eye and neck/shoulder discomfort at baseline and after each task. The cumulative performance time (reflected in the temporal order of the tasks), astigmatism, concurrent eye discomfort, and extent of accommodation all aggravated neck/shoulder discomfort. There was an interaction effect between the temporal order and eye discomfort: participants with a greater mean increase in eye discomfort also developed more neck/shoulder discomfort with time. Since moderate musculoskeletal symptoms are a risk factor for more severe symptoms, it is important to ensure a good visual environment in occupations involving visually demanding near work.

    Intra-rater reliability of the Visual Ergonomics Risk Assessment Method (VERAM)2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Introduction: Visually demanding near work can cause eye discomfort, and eye and neck/shoulder discomfort during, e.g., computer work are associated. Apart from visual demands and dryness a number of environmental factors including design of the work station, lighting, glare, and the quality of the computer screen might exert an impact on eye-related symptoms. To date, there is a lack of valid and reliable instruments assessing factors associated with eye- or visual symptoms. Therefore, a new method to assess visual ergonomics at workplaces was developed in Sweden between 2014 and 2016, the Visual Ergonomics Risk Assessment Method - VERAM. A first version of the method was drafted by the researchers mainly from existing checklists and instruments, and tested in the field by trained visual ergonomists. The method was then revised and used in the field to collect data for validity and reliability analyses. The final version of VERAM includes both a questionnaire for the employee, and an expert evaluation of the employee’s workplace. The questionnaire consists of subjective ratings in six domains: eye discomfort (frequency and intensity), musculoskeletal discomfort (frequency and intensity), ratings of visual symptoms (e.g. blurred and double vision) and ratings of the visual environment (e.g. illumination levels, glare and reflexes from a work object or a computer screen). The expert evaluation consists of both objective measurements and subjective assessments resulting in an overall expert risk assessment (no risk, low risk or high risk) of eight factors: daylight, lighting, illuminance, glare, flicker, work space, work object and work posture.

    Aim: At the IEA conference 2018 the new VERAM method will be presented together with results from intra-rater reliability analyses.

    Results: Intra-rater reliability was evaluated with a re-test interval of minimum two and maximum three weeks. 99 employees were included in the analyses and 32 visual ergonomists performed the corresponding expert evaluations. The Intraclass Correlations (ICC) were between 0.70 and 0.87 for the six subjective domains, and there were no significant systematic differences between the first and second rating for any of the subjective domains (rmANOVA, p > 0.05, α = 0.008). For the eight environmental factors the expert estimated the risk equally during the first and the second assessment in 69-92% of the cases, and, as seen for the subjective domains, there were no significant systematic differences for any of the eight factors (Wilcoxon sign rank test, p > 0.014, α = 0.006). To control for multiple comparisons the Bonferroni method was used.

    Conclusion: The Visual Ergonomics Risk Assessment Method – VERAM showed good intra-rater reliability, both for the subjective questionnaire for the employee, and for the expert evaluation of the employee’s workplace when performed by a trained visual ergonomist.

    Lighting, visual ergonomics and health implications : A workshop2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Aim of the workshop:

    Deficient visual ergonomics is a problem across many occupations. Poor viewingand lighting conditions is associated with both visual and neck/shoulder discomfort,and can also impact productivity. According to the provision from the Swedish WorkEnvironment Authority on prevention of musculoskeletal disorders (AFS 2012:02), riskassessment of the visual conditions are mandatory. The aim of this workshop is toincrease knowledge about visual ergonomics among practitioners working with riskassessment, and to allow participants hands-on practice in assessing the visual environment.

    Format of the workshop:

    The first part of the workshop will involve a brief presentation of the subject visualergonomics and its implications on health and performance. The impact of progressiveglasses, too small or blurred font letters, or blurred vision on posture at e.g. computerwork will be demonstrated together with advice how to proceed to improve the conditions.The second part of the workshop will allow participants some hands-on practicein for example; how to measure light (luminance and illuminance); how different lightconditions impact pupil size and visual comfort; how to measure and quantify amountof flicker, light modulation and colour rendering in different light sources. Several usefulmobile phone applications concerning light and vision will be demonstrated.

    Workshop in visual ergonomics2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Increased use of computers is common across many work sectors. Prolonged near work at a computer screen is associated with both visual discomfort and neck/shoulder discomfort and pain. Inadequate visual ergonomics at a computer workstation can also influence both visual and neck/shoulder discomfort. The new provision from the Swedish Work Environment Authority on prevention of musculoskeletal disorders includes risk assessment of occupational visual conditions. These assessments require practitioners to have knowledge of the topic, as well as experience with practical assessment tools.

    The first part of the workshop proposed here will involve a presentation of the theories underlying visual ergonomic practices and a discussion of the most important factors to assess at a computer workstation. These factors include contrast, font size, resolution, glare, reflexion, non-visual flicker, and edge sharpness. The second part of the workshop, will allow participants hands-on practice in measuring and evaluating visual ergonomics at a computer workstation.

    Temporal co-variation between eye lens accommodation and trapezius muscle activity during a dynamic near-far visual task2015Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, nr 5, artikkel-id e0126578Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Near work is associated with increased activity in the neck and shoulder muscles, but the underlying mechanism is still unknown. This study was designed to determine whether a dynamic change in focus, alternating between a nearby and a more distant visual target, produces a direct parallel change in trapezius muscle activity. Fourteen healthy controls and 12 patients with a history of visual and neck/shoulder symptoms performed a Near-Far visual task under three different viewing conditions; one neutral condition with no trial lenses, one condition with negative trial lenses to create increased accommodation, and one condition with positive trial lenses to create decreased accommodation. Eye lens accommodation and trapezius muscle activity were continuously recorded. The trapezius muscle activity was significantly higher during Near than during Far focusing periods for both groups within the neutral viewing condition, and there was a significant co-variation in time between accommodation and trapezius muscle activity within the neutral and positive viewing conditions for the control group. In conclusion, these results reveal a connection between Near focusing and increased muscle activity during dynamic changes in focus between a nearby and a far target. A direct link, from the accommodation/vergence system to the trapezius muscles cannot be ruled out, but the connection may also be explained by an increased need for eye-neck (head) stabilization when focusing on a nearby target as compared to a more distant target.

    The relationship between low vision and musculoskeletal complaints: A case control study between age-related macular degeneration patients and age-matched controls with normal vision2009Inngår i: Journal of Optometry, ISSN 1888-4296, Vol. 2, nr 3, s. 127-133Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Age-related Macular Degeneration (AMD) patients often describe complaints from neck and scapula area muscles and a decreased postural control. In clinical assessment, these complaints are considered to be due to old age. Purpose: This study focuses on low vision patients with AMD, compared to age matched controls, without eye disease, in order to evaluate if a linkage between self-rated visual and muskuloskeletal complaints are more prominent when low vision is present. Methods: In a cross-sectional study, 24 AMD patients, aged 65-85 years, were compared to 24 controls of similar ages without visual problems. Visual acuity, the need for magnification plus other optical and visual data, were obtained. Visual, muskuloskeletal and balance/propriopceptive complaints were collected with a self-rating questionnaire. The Visual Functioning Questionnaire -Near Activities Subscale (VFQ-NAS) was used to evaluate visual function and related complaints. Results: The correlation coefficient between visual and musculoskeletal complaints yielded significant values when computed separately within each group as well as when calculated on the entire material (AMD ρ = 0.60, P = 0.002; control group ρ = 0.59, P = 0.004; both groups together ρ = 0.50 P < 0.001). Stepwise multiple regression analysis supported the hypothesized effect of vision (Visual complaints + Minimal readable typefaces) on musculoskeletal complaints, (R2 = 0.42, P < 0.05). Conclusions: The results in this study support the hypothesis of a relationship between visual and muskuloskeletal problems.

    Visual, musculoskeletal and balance symptoms in individuals with visual impairment and with age-normal vision2019Inngår i: Clinical and experimental optometry, ISSN 0816-4622, E-ISSN 1444-0938, Vol. 102, nr 1, s. 63-69Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND:

    Visual impairment is globally among the most prevalent disabilities. Research concerning the health consequences of visual deficits is challenged by confounding effects of age, because visual impairment becomes more prevalent with age. This study investigates the influence of visual deficits on visual, musculoskeletal and balance symptoms in adults with and without visual impairment, while controlling for age effects.

    METHODS:

    Thirty-nine patients with visual impairment, aged 18-72 years, were compared to 37 age-matched controls with normal vision, allocated to two age groups: < 45 and ≥ 45 years. Self-reported symptoms were measured using the Visual, Musculoskeletal and Balance Symptoms Questionnaire and compared with demographic and optometric variables.

    RESULTS:

    In total, patients with visual impairment reported more symptoms than age-matched normally sighted controls. Younger adults in the control group were almost free from symptoms, whereas younger adults with visual impairment reported levels of symptoms equal to older adults with visual impairment. Multiple logistic regression modelling identified use of eyeglasses, magnifying aids and presence of anisometropia to be the most influential risk factors for reporting visual, musculoskeletal and balance symptoms, with accentuated influence on balance symptoms.

    CONCLUSIONS:

    People with visual impairments and people with age-related normal visual deficits are both predisposed to report visual, musculoskeletal and balance symptoms relative to people without visual defects or need for eye-wear correction. Age-related variations in symptoms were observed in the control groups but not in the visual impairment groups, with younger visual impairment patients reporting as many symptoms as older visual impairment patients. These findings indicate a need for a wider interdisciplinary perspective on eye care concerning people with visual impairment and people with need for habitual daily use of eye wear correction.

    Visual, Musculoskeletal, and Balance Complaints in AMD: A Follow-Up Study2016Inngår i: Journal of Ophthalmology, ISSN 2090-004X, E-ISSN 2090-0058, Vol. 2016, artikkel-id 2707102Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose. To investigate whether patients with age-related macular degeneration (AMD) run a potentially higher risk of developing visual, musculoskeletal, and balance complaints than age-matched controls with normal vision. Methods. Visual assessments, self-rated visual function, self-rated visual, musculoskeletal, and balance complaints, and perceived general health were obtained in 37 AMD patients and 18 controls, at baseline and after an average of 3.8 years later. Results. At follow-up both groups reported decreased visual acuity (VA) and visual function, but only AMD patients reported significantly increased visual, musculoskeletal, and balance complaints. Decreased VA, need for larger font size when reading, need for larger magnification, and decreased self-rated visual function were identified as risk markers for increased complaints in AMD patients. These complaints were also identified as risk markers for decreased health. For controls, decreased VA and self-reported visual function were associated with increased visual and balance complaints. Conclusions. Visual deterioration was a risk marker for increased visual, musculoskeletal, balance, and health complaints in AMD patients. Specifically, magnifying visual aids, such as CCTV, were a risk marker for increased complaints in AMD patients. This calls for early and coordinated actions to treat and prevent visual, musculoskeletal, balance, and health complaints in AMD patients.
