  Background: Amyoplasia, the most common form of arthrogryposis is characterized by typical deformities of the joints and replacement of skeletal muscles by fibrous tissue and fat. There is sparse literature on adaptation to adult life with amyoplasia. Purpose: To describe physical function and activity strategies in adults with amyoplasia, as this knowledge is important for relevant function-enhancing measures. Materials and methods: Twenty-two adults (20–91 years) with amyoplasia participated. Demographic factors and clinical history were registered. Body proportions were measured. Joint mobility and muscle strength in the upper limbs were examined. The Functional Independent Measure was used to assess performance of activities of daily living. Compensatory strategies were described. Results: The majority had undergone comprehensive conservative and surgical treatment. Mean height was below typical. Range of motion was below lower limit of normal in most joints, passive range of motion was mainly larger than active. Muscle strength was reduced for most movements. Seven were independent in all activities. Need of assistance was highest regarding bathing and dressing. A variety of compensatory strategies were used. Conclusions: Adults with amyoplasia are heterogeneous regarding function. Independence in everyday life requires a combination of muscle strength to move against gravity, ability to passive joint motion, and use of compensatory strategies.

  BACKGROUND: Accomplishment of a series of successive hops is an advanced motor skill and requires adequate timing and coordination. Hopping on one leg performance might therefore be a more sensitive test with higher discriminatory power than ordinary gait in evaluating motor competence both in healthy and diseased children. OBJECTIVE: The purpose of the study was to develop a normative sample on walking at a normalized speed of 1.5m/s and hopping on one leg parameters in children 7-12 years of age, and to evaluate the influence of age and gender on the different parameters. METHOD: 360 girls and boys between 7 and 12 years participated in the study. All data were collected using the GAITRite((R)) system. The children were instructed to walk at four different speeds and to hop on either leg with as long serial jumps as possible across the whole walkway. RESULTS: There was an increase in absolute step length of 15% from 7 to 12 years of age. However, for normalized step length there was no increase. The total increase in absolute and normalized hop length from 7 to 12 years was 64% and 36%, respectively. Multiple regression analysis displayed a significant increase for absolute and normalized hopping length with age. CONCLUSION: While step length only showed a small increase from 7 to 12 years of age, hop length showed significant increase both in absolute and normalized values. The variability, however, was large, indicating that a normative sample of hop length measurements includes a wide range of values for each age group.

  BACKGROUND: A number of studies have reported lower muscular strength of the hamstring and the quadriceps and better postural control in female compared with male athletes. Whether those differences are innate and also exist in children and adolescents or are caused by training and participation in different sports is unknown. HYPOTHESIS: Gender differences in hamstring and quadriceps muscular strength and static balance exist even before maturity. STUDY DESIGN: Cross-sectional study; Level of evidence, 4. METHODS: A total of 368 children between 7 and 12 years of age participated in the study. They performed isokinetic concentric hamstring and quadriceps muscle strength measurements at 60 and 240 deg/s and a static balance test using the KAT 2000. Data analysis consisted of independent-samples t tests and multiple regression analysis. RESULTS: Gender had a significant effect on both the hamstring/quadriceps (HQ) ratios and static balance in children between 7 and 12 years of age. Except for the 7-year-old participants, boys showed significantly higher HQ ratios than the girls in every age group, indicating that the hamstring muscles in girls were relatively weak when compared with the quadriceps muscles. There was also a gender effect on the balance index with better balance in girls than boys. CONCLUSION: There is a significant gender difference in HQ ratios and static balance in children between 8 and 12 years of age. Because many children start their handball careers before the age of 10 years, the present findings indicate that prevention programs including hamstring strength training should be prescribed at an earlier age than recommended in previously published studies.

  During working contractions, chemical energy in the form of ATP is converted to external work. The efficiency of this conversion, called 'contraction coupling efficiency', is calculated by the ratio of work output to energy input from ATP splitting. Experiments on isolated muscles and permeabilized fibres show the efficiency of this conversion has a wide range, 0.2-0.7. We measured the work output in contractions of a single human hand muscle in vivo and of the ATP cost of that work to calculate the contraction coupling efficiency of the muscle. Five subjects performed six bouts of rapid voluntary contractions every 1.5 s for 42 s (28 contractions, each with time to peak force < 150 ms). The bouts encompassed a 7-fold range of workloads. The ATP cost during work was quantified by measuring the extent of chemical changes within the muscle from (31)P magnetic resonance spectra. Contraction coupling efficiency was determined as the slope of paired measurements of work output and ATP cost at the five graded work loads. The results show that 0.68 of the chemical energy available from ATP splitting was converted to external work output. A plausible mechanism to account for this high value is a substantially lower efficiency for mitochondrial ATP synthesis. The method described here can be used to analyse changes in the overall efficiency determined from oxygen consumption during exercise that can occur in disease or with age, and to test the hypothesis that such changes are due to reduced contraction coupling efficiency.

  The pathogenesis of widespread pain and fibromyalgia (FM) is unknown. Altered responses from the hypothalamus-pituitary-adrenal axis, sympathetic nervous system and muscular system have been suggested as being of importance. The present study was undertaken to determine: (i) whether the sympathoadrenal response to repetitive isometric contractions until exhaustion is altered in patients with FM, and (ii) whether sympathoadrenal responses are associated with muscle fatigue and pain during exercise. Nineteen women with FM, and 19 healthy women matched for age, smoking and self-reported physical activity, participated. Maximal voluntary contraction (MVC), repetitive isometric contractions (6s contraction and 4s resting phases) were performed with both quadriceps muscles at 30% of MVC until exhaustion. Muscle activity was recorded from the quadriceps muscles by surface electromyography (EMG). Plasma adrenalin (Adr), noradrenalin (NAdr) and cortisol were measured and perceived exertion and pain reported during exercise. Attenuated Adr responses (p<0.001) with normal plasma NAdr and cortisol (p>0.19) responses were found during exercise in the FM group compared with the control group. Significantly higher EMG amplitude (%EMG(max)) during the contraction phases (p=0.001) was found in the FM than in the control group. Perceived exertion and pain responses to exercise were higher in the FM group than in the controls (p<0.001), without relationship to the sympathoadrenal responses. In conclusion; the exercise was perceived as being more painful and strenuous in the FM group. Muscle performance was altered with increased muscle activity during the exercise. Women with FM showed an attenuated Adr response to repetitive isometric exercise.

  AIM: To provide normative age- and gender-associated values on muscular strength, power and endurance and to establish a reference database on healthy school children aged 7 to 12 years. In addition, associations between some simple functional tests and the more sophisticated isokinetic strength measures were investigated. METHODS: Three hundred seventy-six children, 191 girls and 185 boys, performed different muscle-strength tests like knee flexion/extension, handgrip, back extension and vertical jump. RESULTS: There was a significant and linear increase in strength with no gender differences from 7 up to 11 years of age. There was a large variability within each age group, indicating that a normative sample of muscle-strength measurements includes a wide range of values for each age group. The relationship between hand- grip strength and observed quadriceps strength was high (r = 0.84) and the correlation between vertical jump and relative quadriceps strength was moderate (r = 0.50). CONCLUSION: All the different strength measures showed almost the same pattern, indicating increased absolute strength values with increasing age and no significant gender differences except for flexion at the age of 11 and 12 years . The association between grip strength, vertical jump and quadriceps strength measured isokinetically was moderate to strong. The back muscle endurance test (The Biering-Sørensen test) showed a great roof effect and should not be included in a test battery for school children.

  There is limited knowledge on prognostic factors for developing chronic low back pain (LBP) at an early stage of LBP. The objectives of this study were to investigate the clinical course of pain and disability, and prognostic factors for non-recovery after 1-year, in patients seeking help for the first time due to acute LBP. An inception cohort study included 123 patients with acute LBP lasting less than 3 weeks and consulting primary care for the first time. Main outcome measures were pain intensity, Roland-Morris disability questionnaire (RMQ), and sickness absence. Eleven patients (9%) did not return for the 12-month follow-up. There were large and significant reductions in pain intensity (P<0.001) and RMQ scores (P<0.001) during follow-up. Patients with neurological signs showed significantly less improvement in pain (P=0.001) and RMQ (P=0.004) compared with those without neurological signs. The proportions with sickness absence due to LBP at 6, 9, and 12 months were 7%, 8%, and 9%, respectively. At 12 months, 17% of patients had not fully recovered. Multivariate logistic regression analyses showed that high scores on a psychosocial screening (acute low back pain screening questionnaire) and emotional distress (Hopkin's symptom check list) were significantly associated with non-recovery at 12 months, with odds ratios of 4.4 (95% confidence interval 1.1-17.4) and 3.3 (1.1-10.2), respectively.

  We determined the repeatability and correlations between force, endurance and muscle activity during isometric contractions over three years. Twenty-six subjects, with and without complaints of the shoulder and neck, performed standardized maximal and submaximal shoulder-abduction contractions and wrist extension-contractions at yearly intervals from 1997 to 1999. Peak forces developed during maximal contraction and the endurance times of submaximal contractions during shoulder abduction and wrist extension were measured. Electromyography (EMG) of muscle activity was recorded bilaterally from the upper trapezius, middle deltoid, and forearm extensor muscles. Root mean square EMG amplitudes were calculated. We found statistically significant associations between peak forces developed during wrist extension and shoulder abduction, and between endurance times of submaximal wrist extension and shoulder abduction. No statistically significant changes in peak force and EMG(peak) were found over the measurement years. The responses were not statistically significantly influenced by gender, or neck and shoulder pain. However, we observed considerable intra-individual variation in the inter-year measurements particularly for the responses to submaximal contraction. Such large variations represent a challenge when attempting to use the responses to interpret the effects of therapies.

  STUDY DESIGN: Prospective inception cohort study. OBJECTIVES: To compare the clinical course of fear-avoidance beliefs in acute and chronic low back pain (LBP) and investigate the contribution of fear-avoidance beliefs to predict pain and disability after 1 year. SUMMARY OF BACKGROUND DATA: Fear-avoidance beliefs are involved in disability development. There is little knowledge on the development of fear-avoidance beliefs among different LBP subgroups. METHODS: Patients with acute (n = 123) and chronic (n = 50) LBP completed a comprehensive assessment, including the Fear-Avoidance Beliefs Questionnaire (FABQ), and were followed at 3, 6, 9, and 12 months. RESULTS: At baseline, patients with chronic LBP had significantly higher FABQ-scores for work (FABQ-Work) than patients with acute LBP (P < 0.001), and this difference remained unchanged over 1 year (P > 0.21). At baseline, there was no statistical significant difference in FABQ-scores for physical activity (FABQ-PA) between the two groups (P = 0.57). FABQ-PA scores decreased significantly over the first 4 weeks among patients with acute LBP during follow-up and remained unchanged thereafter, whereas in the chronic sample the FABQ-PA scores were unchanged throughout the first year (time effect, P < 0.001; and interaction effect, P < 0.001). In the acute sample, FABQ-Work predicted pain (P < 0.05) and disability at 12 months (P = 0.01). In the chronic sample, FABQ-PA predicted disability at 12 months (P = 0.03). The associations between the FABQ and pain/disability disappeared with distress included in the models. CONCLUSION: Patients with chronic LBP had more fear-avoidance beliefs for work than patients with acute LBP. There were small changes in fear-avoidance beliefs during the year of follow-up, except for a rapid decrease during the first month in the FABQ-PA in the acute sample. Fear-avoidance beliefs predicted pain and disability at 12 months after adjusting for socio-demographic and pain variables. Distress was a stronger predictor than fear-avoidance beliefs.

  OBJECTIVE: To evaluate reliability, validity and responsiveness of the Fear-Avoidance Beliefs Questionnaire (FABQ) for use in Norwegian patients with low back pain. DESIGN: A prospective cohort study with 2 groups. PATIENTS: The questionnaire was tested in 123 patients with acute low back pain and 50 patients with chronic low back pain. METHODS: A translation and cross-cultural adaptation was performed. Test-retest reliability was assessed in 28 patients with chronic low back pain. Responsiveness was assessed in acute low back pain. RESULTS: Two factors for the FABQ were confirmed; fear-avoidance beliefs about work (FABQ-Work) and physical activity (FABQ-PA), accounting for 60% and 54% of the total variance in acute and chronic low back pain, respectively. For FABQ-Work and FABQ-PA internal consistency was 0.90 and 0.79, intra-class correlation coefficients 0.82 and 0.66, minimal detectable changes 12 and 9 points, and coefficients of variation were 16% and 23%. The FABQ correlated weakly to moderately with pain, disability, distress, and clinical variables. Standardized response means were low for FABQ-Work (0.32) and moderate (0.56) for FABQ-PA. Both FABQ subscales showed initially floor and/or ceiling effects. CONCLUSION: The Norwegian FABQ version had acceptable factor structure, internal consistency, test-retest reliability and construct validity. The responsiveness of the FABQ-Work was low, and for the FABQ-PA moderate, in the acute sample.

  Women with pelvic girdle pain (PGP) often consult physical therapists for help and are treated with different therapies without firm evidence for the effectiveness. Two randomized controlled trials have investigated the effect of stabilizing exercises for PGP. The most recent study demonstrated significant positive results in favour of exercises (Stuge et al. The efficacy of a treatment program focusing on specific stabilizing exercises for pelvic girdle pain after pregnancy. A randomized controlled trial. Spine 2004a;29(10):351-9), the other did not (Mens et al. Diagonal trunk muscle exercises in peripartum pelvic pain: a randomized clinical trial. Phys. Ther. 2000;80(12):1164-73). Consequently, the two studies provide contradictory advice for treatment of PGP. The question is thus, whether stabilizing exercises should be recommended as treatment for PGP. Both the studies are of high methodological quality and are comparable with regard to subjects studied. However, there are several differences in the interventions and these are explored and discussed for better understanding of the conflicting results. Exercises that focused on only global muscles showed no effect. However, these exercises were not individualized and they were instructed by videotape. In the more recent study, exercises that initially focused on local muscles, and then gradually added global muscles showed a significant, positive effect. Exercises in that study were supervised, corrected, individualized concerning choice of exercises, order and dosage, and pain was avoided. This comparison indicates that effective treatment of postpartum PGP may be achieved when exercises for the entire spinal musculature are included, individually guided and adapted to each individual.

  Study design. A systematic literature review of outcome questionnaires specificly designed and used for assessing functional status or disabiliy in patients with low back pain. Objectives. To provide a comprehensive overview of all functioning/disability questionnaires used the last years, and classify the content of the questionnaires in order to identify the concept(s) and construct(s) reflected in the questionnaires. Summary of background data. A number of clinical tools designed for evaluating the functional status of patients with low back pain have been developed. There has been little focus on the differences in content of the questionnaires and the concepts and constructs reflected in these. Methods. Papers including questionnaires for assessing disability, function, activity limitations, or participation restrictions in adult patients (> 18 years) with low back pain were searched in the Medline and Cinahl databases for the period January 1996-2002. ¿Back pain¿ and ¿low back pain¿ were combined with relevant terms. Hand-searches were carried out in journals and textbooks. Two independent and blinded researchers read and selected abstracts and questionnaires. The content of the included questionnaires was catehegorized into impairments, activities of daily living and social function as well as subgroups of these. Results. A total of 35 back-specific questionnaires were identified. A considerable variation with respect to content was found. All outcome questionnaires assessed activities of daily living and a majority also assessed social functions and bodily aspects such as pain and symptoms, sleep disturbances, psychological dysfunctions, and/or physical impairments. Seven questionnaires assessed solely activities of daily living. Several questionnaires also included other constructs. Conclusions. The outcome questionnaires differed with regard to content, concept(s) and construct(s), thus reflecting different interpretations of disability.

ISSN 0004-3591. 53(1), s. 5–11. Vis sammendrag

  OBJECTIVE: To investigate 1) levels of fatigue in patients with ankylosing spondylitis (AS) compared with the general population; 2) the relationships between fatigue and demographic, self-reported, and clinical measures; and 3) the performance of both a generic and a disease-specific measure of fatigue. METHODS: Patients with AS (n = 152) were compared with people from the general population (n = 2,323). Fatigue was assessed by the Short Form 36 (SF-36) vitality scale and the fatigue item of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Other measures of self-reported health included BASDAI for disease activity, Bath Ankylosing Spondylitis Functional Index for functional abilities, and the SF-36 for mental health. Clinical measures comprised Bath Ankylosing Spondylitis Metrology Index for joint mobility and erythrocyte sedimentation rate and C-reactive protein as inflammatory markers. The explanatory power of demographic, self-reported, and clinical measures was examined in a block regression model. RESULTS: The mean +/- SD SF-36 vitality score was 43 +/- 24 in the patients and 60 +/- 21 in the general population (P < 0.001). The SF-36 vitality and the BASDAI fatigue scores were consistently associated with measures of mental health and disease activity. Clinical measures did not show explanatory power. A cutoff at 70 mm on the BASDAI fatigue item implied specificity of 0.77 and sensitivity of 0.82. CONCLUSION: Self-reported measures of disease activity and mental health contributed significantly to explain fatigue, whereas clinical measures of inflammation and joint mobility did not. The BASDAI fatigue item reached acceptable sensitivity and specificity with a cutoff at 70 mm when using the low vitality scores of SF-36 as an external indicator.

  STUDY DESIGN: Inception cohort study. OBJECTIVES: To examine the clinical course of acute low back pain and to evaluate prognostic factors for nonrecovery. SUMMARY OF BACKGROUND DATA: Few studies have explored clinical course and prognostic factors in patients who consult primary care for their first time because of an episode of low back pain of <3 weeks duration. METHODS: A total of 123 patients with acute low back pain <3 weeks consulting primary care for the first time were included, and 120 completed 3 months follow-up. Baseline assessments included sociodemographic characteristics, back pain history and current status, psychological questionnaires and clinical examination. Main outcome measures were pain intensity, disability by Roland Morris Disability Questionnaire, and recovery of disability. Potential prognostic factors for recovery or not were analyzed by multivariate logistic regression. RESULTS: At 4 weeks and 3 months 76% of the patients had recovered. Mean pain intensity and mean disability scores dropped 58% and 68%, respectively, of initial levels during the 3 months. The proportion with sickness absence was 8% at 4 weeks and 6% at 3 months. Several sociodemographic, clinical, and psychological factors were of prognostic value. Compared with their respective reference categories, age above 45 years (odds ratio 4.4, 95% confidence interval 1.4-14.0), smoking (3.0, 1.1-8.5), two or more neurological signs (4.6, 1.4-14.9), a score of >or=90 on the psychosocial screening (3.1, 1.0-9.4), and high levels of distress (4.1, 1.3-12.8) were the best prognostic factors of nonrecovery at 3 months. CONCLUSION: During a period of 3 months, 24% of the patients had not recovered. Psychological factors and neurological signs were strongly associated with nonrecovery at 3 months. In addition to the traditional examination of neurological symptoms and signs, psychological factors should be considered already at the initial visit of an episode of low back pain.

  Professor i forebyggende medisin, dr.med. Tor Bjerkedal døde 11. 6. 2015, 88 år gammel. Etableringen av Medisinsk fødselsregister kom til å bli hans livsverk, og dette arbeidet var han engasjert i inn til det siste. Tor Bjerkedal deltok i motstandsarbeid under den annen verdenskrig, og han satt på Grini deler av krigsårene. Etter krigen fikk han plass på legestudiet i København, der han også traff den danske tannlegestudenten Gudrun Kjerulff som ble hans kone. Sammen fikk de tre barn, seks barnebarn og tre oldebarn. I 1952 fullførte Bjerkedal legeutdanningen ved Universitetet i Oslo. Han arbeidet deretter et års tid som distriktslege i Vik i Sogn før han i 1954 ble vitenskapelig assistent ved Hygienisk Institutt i Oslo. Bjerkedal hadde flere forskningsopphold i USA og tok mastergrad i folkehelse ved Harvard i 1958. Sin doktorgrad om tuberkulose forsvarte han ved Universitetet i Oslo i 1965, og året etter ble han styrer for Institutt for hygiene og sosialmedisin ved Universitetet i Bergen. Gjennom sin tilknytning til Statistisk sentralbyrå ble Bjerkedal engasjert i arbeidet med den medisinske fødselsmeldingen. Han overbeviste raskt alle involverte parter om at dette datagrunnlaget i forskning og helsetjeneste burde knyttes til et aktivt medisinsk forskningsmiljø. I 1970 etablerte Bjerkedal Medisinsk fødselsregister, verdens første i sitt slag. Han var en drivende kraft i nordisk og internasjonalt samarbeid innenfor dette fagfeltet. Videre gjennomførte han forsøk med nye rutiner for systematisk og standardisert registering av helseopplysninger om småbarn, med mål om å effektivisere helsestasjonsarbeidet. Han etablerte også et system, SYSVAK, for registrering av alle vaksinasjoner utført på småbarn og skolebarn. Bjerkedal tok tidlig i bruk informasjonsteknologi, noe han ble en pådriver for å innføre i helsevesenet. Her møtte han en rekke tilbakeslag og frustrasjoner. Selv i sine senere år kunne han registrere at hans visjoner ennå langt fra var realiserte. I 1976 ble Bjerkedal styrer for Institutt for forebyggende medisin, Universitetet i Oslo. Han var arbeidsom og utholdende, og ble en nestor i forebyggende medisin og epidemiologi. Samtidig var han en visjonær og hjelpsom kollega. Noen kunne kanskje oppleve hans krav til kvalitet og nøyaktighet som en utfordring. Men kanskje ikke alle så de samme mulighetene som Bjerkedal selv så, eller riktig forsto hans kraftfulle personlighet og de mange visjonene som var en naturlig del av hans liv. Kanskje hadde tiden på Grini og oppholdene i USA også satt sitt preg på hans visjonære, kvalitetsbevisste, kritiske og handlekraftige måte å arbeide på? Han var veileder for en rekke stipendiater og forskere, noe som bidro til å gi ham en bred akademisk kompetanse innen samfunnsmedisin. Hans store lidenskap var registerepidemiologi for å finne årsaker til sykdom. Dette ga mulighet for helsefremmende og forebyggende tiltak. Han forsket også på arbeidsmedisin, infeksjonsmedisin, kreftsykdommer, trygdemedisin og initierte global helseforskning i Palestina. I sin lange pensjonisttid publiserte Bjerkedal over 50 artikler. Da han var 76 år, etablerte han en fødselskohort basert på de ti første årgangene i Medisinsk fødselsregister og koblet denne til et flertall nasjonale registre. Dette har resultert i et stort antall originalartikler, også i Science. Samarbeidet med Haakon Natvig på Hygienisk institutt i 1960-årene omfattet en oppfølging av det såkalte «oljeforsøket». Bjerkedal fulgte opp denne kohorten helt til de yngste gjenlevende var over 90 år gamle. Siste publikasjon med ham som førsteforfatter sto i Tidsskriftet i 2012. En visjonær og hjelpsom kollega har gått bort. Varm takk til vår venn Bjerkedal for hans innsats til folkehelsens beste. Våre tanker går til Gudrun og øvrige familie. På vegne av kolleger tilknyttet Universitetet i Oslo og Universitet i Bergen

Metoder og verktøy Ett hovedmål er å utvikle og etablere metoder for standardisert registrering av data som er relevante for klinisk praksis. Dette gjør vi gjennom å utvikle og teste ut kjernesett av metoder som gir relevante opplysninger om pasientene, hvilken behandling de får og hvordan de responderer på behandlingen. I ett delprosjekt har vi et særlig fokus på måleinstrumenter for fysisk form, der metodiske egenskaper for aktuelle spørreskjemaer og fysiske tester undersøkes. Muligheten for klinisk nytte og anvendelse er førende for utviklingen og etableringen av metodene, samtidig som en systematisk registering av kliniske data også vil kunne gi bedre grunnlag for forskning i primærhelsetjenesten. Kliniske studier og forløpsstudier I FYSIOPRIM gjennomføres flere kliniske studier som har til hensikt å skape kunnskap om kliniske forløp, samhandlingsprosesser og behandlingseffekter (inkludert kost:nytte). Tre studier er lagt opp som randomiserte kontrollerte kliniske (RCT) studier, hvorav to undersøker effekten av intervensjon for personer som har artrose i knær og/eller hender. Videre skal det undersøkes om behandlingen av artrosepasienter følger anbefalinger i gjeldende internasjonale retningslinjer. I en annen RCT undersøkes bevegelsesmønster og motorisk kontroll hos pasienter med nakkesmerter, om ordinær fysioterapibehandling påvirker motorisk avvik og om avviksmønster kan knyttes til symptomendringer. For å få mer innsikt i samhandlingsprosessene mellom pasient og terapeut og i de individuelle forløpene, har vi også en studie av nakkepasienter der kvalitativ og kvantitativ tilnærming kombineres. Til sammen vil disse kliniske studiene kunne gi et fundament for videreutvikling av klinisk praksis og muligheter for mer tilpasset behandling. Det er lagt opp til to forløpsstudier, der den ene tar utgangspunkt i en befolkningsstudie (HUNT3) og følger en gruppe personer med nyoppståtte rygg- og nakkeplager gjennom ett års tett oppfølging. Den andre forløpsstudien vil ta utgangspunkt i pasienter som søker behandling hos privatpraktiserende fysioterapeuter og vi vil følge dem gjennom og etter en behandlingsperiode. Her benyttes registreringsmetodene vi har utviklet (se ovenfor). Antallet pasienter i denne gruppen vil bli så stort at vi kan studere forskjellige pasientgrupper (f. eks. nakke- eller ryggplager), og derved sammenligne med andre studier i FYSIOPRIM (og utenfor). Gjennom forløpsstudiene vil vi også identifisere prediktorer for langvarige plager. Modeller for samarbeid Et helt sentralt mål for FYSIOPRIM er å prøve ut ulike samarbeidsmodeller mellom fysioterapeuter i primærhelsetjenesten og forskere. Slik vil vi skape grunnlag for bedre samarbeid og derved sikre varig økt forskningsinnsats i primærhelsetjenesten, og bedre tjenester i fremtiden. Dette gjøres på flere måter. For det første har vi gjennom hele prosjektperioden et formalisert samarbeid med fysioterapeuter fra primærhelsetjenesten. Disse deltar regelmessig i diskusjoner i alle faser av prosjektet og har derved en gjennomgående påvirkning på forskningen. Samarbeidet har også ført til at forskerne har deltatt i samtaler med administrasjonen i kommunene om hvordan vi best kan samarbeide om forskning og bruk av forskningsresultater. Vi har nylig utlyst hospitantstillinger for å prøve ut samarbeidsformer mellom klinikere og forskere enda bredere. Det er vår ambisjon at det nære samarbeidet mellom forskere og klinikere vil synliggjøre gevinster i form av positive effekter for klinisk praksis, og at det bidrar til at viktige spørsmål fra primærhelsetjenesten blir tatt opp av forskerne.
