Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I MQ-FAS studien, vars syfte var att ändra muskelspänningsmönstret hos kvinnor med kroniska nackbesvär, ingick ett besticktorkningsmoment som en standardiserad arbetsuppgift i hemmet. För validering av denna besticktorkning har en pilotstudie genomförts, 12 personer torkade bestick vid två tillfällen. I studien, som utfördes av 2 testledare, ingick även ett finmotorikstest (Purdue Pegboard), ansträngningsskattning (Borg RPE-skalan) samt ett frågeformulär. Detta test kan med vissa justeringar troligen vara användbart som ett mått på arbetsförmåga av övre extremiteter vid utförande av arbetssyssla i hemmet, och jämföra individ med sig själv, för att mäta om funktionsnedsättning eller ökning har skett. Dock skall poängteras att detta var en pilotstudie och ytterligare studie av reliabilitet och validitet rekommenderas innan testet används i stor utsträckning för att mäta om funktionsnedsättning eller ökning har skett.

- Abstract The theoretical framework is that muscle tension in the neck is related to insufficient muscular rest and is a risk factor for chronic pain and reduced work ability. Promoting muscle strength and muscle rest may increase work ability and reduce neck pain. Objectives To test whether myofeedback training or intensive strength training leads to decreased pain and increased work ability in women on long-term sick leave. Methods This is a randomized controlled trial of two 1-month interventions with myofeedback or muscular strength training in the home environment. Female human service organization workers (n = 60) on long-term (>60 days) sick leave and with chronic neck pain were followed with self-reported and laboratory-observed data of health, pain, muscular activation, and work ability, at baseline, immediately after the intervention and 3 months after baseline. Results For both intervention groups, pain was lowered over time compared with the control group. Decreased pain and muscular activity was associated with increased self-rated work ability and with laboratory-observed work ability at 3-month follow-up. Decreased pain was also associated with increased self-rated work ability at 1-month follow-up. Muscular strength training was associated with increased self-rated work ability and mental health. Myofeedback was associated with increased observed work ability and self- rated vitality. Conclusions The two interventions showed positive results, suggesting that they could be developed for use in health care practice to address pain and work ability. The intensive muscular strength training program, which is both easy to conduct at home and easy to coach, was associated with increased work ability.

- Background The risk of developing vibration white fingers and neurosensory symptoms increases with the duration and intensity of the exposure. The aim of this study was to investigate the risk of developing vibration white fingers (VWF), neurosensory symptoms and musculoskeletal disorders among workers exposed to transient and high frequency vibrations. Methods The study included 38 vibration exposed workers from a loader assembly plant in Sweden (30 males and 8 females). All participants answered questionnaires and had a structured interview about work and medical history. A following medical examination included the determination of vibration and temperature perception thresholds and musculoskeletal symptoms in the neck, shoulder, elbow and hands. The individual vibration exposure expressed as A (8)-values and vibration exposure in minutes per day, were obtained from questionnaires answered by the participants. Results The prevalence of VWF was 30% among the male workers and 50% among the females. The corresponding prevalence of neurosensory symptoms was 70% among the males and 88% among the females. Musculoskeletal findings were common among the male workers. Dominant symptoms/syndromes were tension neck syndrome, biceps tendinitis, carpal tunnel syndrome and ulnar entrapment in hand/wrist. A total of 32 diagnoses were observed among the male workers and four diagnoses among the female workers. Numbness in fingers and age had the strongest impact on perceived work ability. Conclusions ISO 5349-1 considerably underestimates the risks of VWF for this group of workers exposed to transient and high frequency vibrations. It is therefore important to develop a risk assessment standard also covering this frequency range.

- Purpose The development of vascular and neurosensory findings were studied in two groups of long-term exposed quarry and foundry workers with different vibration exposures, working conditions and work tasks. Methods The study included 10 quarry workers (mean age 43 yrs., mean exposure time 16 yrs.) and 15 foundry workers (35 yrs.; 11 yrs.) at two plants in Sweden. All participants completed a basic questionnaire and passed a medical examination including a number of neurosensory tests, e.g. the determination of vibration (VPT) and temperature (TPT) perception thresholds as well as a musculoskeletal examination of the neck, shoulders, arms and hands. Results A high prevalence of neurosensory findings (40%) was found among the quarry workers. Both groups, however, showed a low prevalence of vibration white fingers (VWF). Foundry workers showed significantly better sensitivity than quarry workers for all monofilament tests (p <= 0.016), TPT warmth in dig 2 (p = 0.048) and 5 dexter (p = 0.008), and in dig 5 sinister (p = 0.005). They also showed a better VPT performance in dig 5 dexter (p = 0.031). Conclusions Despite high vibration exposure, the prevalence of VWF was low. The high prevalence of neurosensory findings among the quarry workers may depend on higher A(8) vibration exposure and higher exposure to high-frequency vibrations. An age-effect and exposure to cold could also be contributing factors. The nervous system seems to be more susceptible to high-frequency vibrations than the vascular system. For neurosensory injuries, the current ISO 5349-1 standard is not applicable.

Tidskriftsartikel (refereegranskat)abstract
- Background To investigate the development of pain intensity and pressure pain thresholds during and 24 h after a light dynamic physical load among patients with chronic neck-shoulder pain. Methods Twenty-six patients with chronic neck-shoulder pain and 12 healthy controls were included. The participants arm-cycled on an ergometer. Effort was rated with the Borg Rating of Perceived Exertion scale (RPE), and pain intensity with an numeric rating scale (NRS). Pressure pain thresholds were measured by an algometer. Participants started a pain diary 1 week before the physical exercise and continued until 1 week after. Pain intensity was assessed before, during and the following two evenings after arm-cycling. Pressure pain thresholds were assessed before, 15 min after, 105 min after and 24 h after. Results The chronic pain group showed increased pain intensity during, and the following two evenings after the arm cycling, and decreased pain thresholds immediately after the arm cycling involving painful regions. In the patient group there were no impact on pain thresholds in the neck the following day. Conclusions Patients with chronic neck-shoulder pain reported increased pain intensity during and in the evenings after a light dynamic load involving painful regions. In addition, they showed decreased pain thresholds close to the exercise, indicating mechanical hyperalgesia.

Test av ett datoriserat uppmärksamhetstest: Påverkar språket resultaten? En jämförelse av amerikansk originalversion och svensk version av IVA
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- IVA+Plus Inte grated Visual and Auditory Continuous Performance Test (IVA+) är ett amerikanskt dator iserat test som mäter auditiv och visuell uppmärksamhet. I samband med forskningsprojektet GODA testades försökspersoner och deras kontroller med ett IVA+ som anpassats till svenska. Preliminära resultat i studien tydde på en snedfördelning mellan auditiva och visuella delskalor. En studie genomfördes därför med syfte att jämföra den amerikanska originalversionen och den svenska anpassade versionen. Tjugosju personer i åldrarna 18 - 60 år testades med IVA+ två gånger med 7 - 20 dagars mellanrum (mv 8,08), ena gången med den amerikanska originalversionen och andra gången med den svenska versionen. Hälften började med den amerikanska och hälften med den svenska versionen. De två språkversionerna skiljde sig åt genom att auditiv responstid var något snabbare i d en svenska versionen (33 ms). Desto större skillnader framkom dock mellan auditiv och visuell responstid inom både den amerikanska och den svenska versionen av IVA+. Auditiv responstid var i båda språkversionerna mer än 1 standardavvikelse bättre än det no rmerade genomsnittet, medan visuell responstid låg nära förväntat värde. Skillnader framkom också i ytterligare några subskalor. Det visade sig i kontakt med testförlaget BrainTrain Inc, att det varit känt sedan 2011 att den svenska ljudfilen var något sna bb och att detta hade korrigerats för i senare versioner av testet. Genom att lägga till 31 ms till de auditiva responserna i vårt dataset kunde skillnaderna mellan språkversionerna jämnas ut. Oavsett detta, tycks både originalversionen och den anpassade s venska versionen av IVA+ ha innehållit ett systematiskt fel som ger ett bättre än förväntat resultat avseende auditiv snabbhet vid våra datainsamlingar. Bl a testledareffekt och selektionsbias diskuteras som tänkbara förklaringar till resultaten. Mest sann olikt är dock att något i tekniken påverkar resultaten, t ex genom en felklockning av stimuli och/eller respons. Detta gör att de standardiserade normerna knappast kan tillämpas på den insamlade datan. På grund av osäkerheten i vad felet består krävs stor försiktighet även vid framtida datainsamling och särskilt vid klinisk tillämpning av testresultaten. I forskningsstudier bör det vara mindre problematiskt så länge testningarna används för att jämföra grupper eller för att göra för - och eftermätningar för att t ex utvärdera en intervention, dvs där resultaten kan vara oberoende av normeringen. Det är dock troligtvis viktigt att samma hård - och mjukvara används till samtliga testningar.
