    • OBJECTIVE The aim of this study was to evaluate the 5- to 8-year outcome of anterior cervical decompression and fusion (ACDF) combined with a structured physiotherapy program as compared with that following the same physiotherapy program alone in patients with cervical radiculopathy. No previous prospective randomized studies with a follow-up of more than 2 years have compared outcomes of surgical versus nonsurgical intervention for cervical radiculopathy. METHODS Fifty-nine patients were randomized to ACDF surgery with postoperative physiotherapy (30 patients) or to structured physiotherapy alone (29 patients). The physiotherapy program included general and specific exercises as well as pain coping strategies. Outcome measures included neck disability (Neck Disability Index [NDI]), neck and arm pain intensity (visual analog scale [VAS]), health state (EQ-5D questionnaire), and a patient global assessment. Patients were followed up for 5-8 years. RESULTS After 5-8 years, the NDI was reduced by a mean score% of 21 (95% CI 14-28) in the surgical group and 11% (95% CI 4%-18%) in the nonsurgical group (p = 0.03). Neck pain was reduced by a mean score of 39 mm (95% CI 26-53 mm) compared with 19 mm (95% CI 7-30 mm; p = 0.01), and arm pain was reduced by a mean score of 33 mm (95% CI 18-49 mm) compared with 19 mm (95% CI 7-32 mm; p = 0.1), respectively. The EQ-5D had a mean respective increase of 0.29 (95% CI 0.13-0.45) compared with 0.14 (95% CI 0.01-0.27; p = 0.12). Ninety-three percent of patients in the surgical group rated their symptoms as "better" or "much better" compared with 62% in the nonsurgical group (p = 0.005). Both treatment groups experienced significant improvement over baseline for all outcome measures. CONCLUSIONS In this prospective randomized study of 5- to 8-year outcomes of surgical versus nonsurgical treatment in patients with cervical radiculopathy, ACDF combined with physiotherapy reduced neck disability and neck pain more effectively than physiotherapy alone. Self-rating by patients as regards treatment outcome was also superior in the surgery group. No significant differences were seen between the 2 patient groups as regards arm pain and health outcome.

  • Perceived pain extent is associated with disability, depression and self-efficacy in individuals with whiplash-associated disorders
  • 2016

    • BackgroundCompletion of a pain drawing is a familiar task in those presenting with whiplash-associated disorders (WAD). Some people report pain almost over their entire body. Yet the reasons for larger pain extent have not been fully explored. MethodsA novel method was applied to quantify pain extent from the pain drawings of 205 individuals with chronic WAD. Pain extent was evaluated in relation to sex, age, educational level, insurance status and financial status. Multiple linear regression analysis was used to verify whether pain extent was associated with other health indicators including perceived pain and disability, health-related quality of life, pain catastrophizing, anxiety, depression and self-efficacy. ResultsPain extent was influenced by sex ((2):10.392, p<0.001) with larger pain extent in women compared to men (7.887.66% vs. 5.406.44%). People with unsettled insurance claims ((2): 7.500, p<0.05) and those with a worse financial situation ((2):12.223, p<0.01) also had larger pain extent. Multiple linear regression models revealed that, when accounting for age, sex, education, insurance status, financial status and neck pain intensity, pain extent remained associated with perceived disability (p<0.01), depression (p<0.05) and self-efficacy (p<0.001). ConclusionBy utilizing a novel method for pain extent quantification, this study shows that widespread pain is associated with a number of factors including perceived disability, depression and self-efficacy in individuals with chronic WAD. Widespread pain should alert the clinician to consider more specific psychological screening, particularly for depression and self-efficacy, in patients with WAD. What does this study add?Women with chronic WAD, those with unsettled insurance claims and those with poorer financial status perceive more widespread pain. When controlling for these factors, larger pain areas remain associated with perceived pain and disability, depression and self-efficacy. The pain drawing is useful to support psychological screening in people with chronic WAD.

  • Altered patterns of displacement within the Achilles tendon following surgical repair
  • 2017

    • Ultrasound speckle tracking was used to compare tendon deformation patterns between uninjured and surgically repaired Achilles tendons at 14-27-month follow-up. The hypothesis was that the non-homogenous displacement pattern previously described in uninjured tendons, where displacement within deep layers of the tendons exceeds that of superficial layers, is altered following tendon rupture and subsequent surgical repair. In the first part of this study, an in-house-developed block-matching speckle tracking algorithm was evaluated for assessment of displacement on porcine flexor digitorum tendons. Displacement data from speckle tracking were compared to displacement data from manual tracking. In the second part of the study, eleven patients with previous unilateral surgically treated Achilles tendon rupture were investigated using ultrasound speckle tracking. The difference in superficial and deep tendon displacement was assessed. Displacement patterns in the surgically repaired and uninjured tendons were compared during passive motion (Thompson's squeeze test) and during active ankle dorsiflexion. The difference in peak displacement between superficial and deep layers was significantly (p < 0.01) larger in the uninjured tendons as compared to the surgically repaired tendons both during Thompson's test (-0.7 +/- 0.2 mm compared to -0.1 +/- 0.1 mm) and active dorsiflexion (3.3 +/- 1.1 mm compared to 0.3 +/- 0.2 mm). The evaluation of the speckle tracking algorithm showed correlations of r ae 0.89 between displacement data acquired from speckle tracking and the reference displacement acquired from manual tracking. Speckle tracking systematically underestimated the magnitude of displacement with coefficients of variation of less than 11.7%. Uninjured Achilles tendons display a non-uniform displacement pattern thought to reflect gliding between fascicles. This pattern was altered after a mean duration of 19 +/- 4 months following surgical repair of the tendon indicating that fascicle sliding is impaired. This may affect modulation of the action between different components of the triceps surae, which in turn may affect force transmission and tendon elasticity resulting in impaired function and risk of re-rupture.

    • Objective: To compare short-and long-term changes in neck muscle endurance, electromyography measures of neck muscle activation and fatigue and ratings of fatigue and pain after neck-specific training or physical activity in people with cervical radiculopathy. Design: Randomized clinical trial. Subjects/patients: Seventy-five patients with cervical radiculopathy. Methods: Patients underwent neck-specific training in combination with a cognitive behavioural approach or prescribed physical activity over a period of 14 weeks. Immediately after the intervention and 12 months later, surface electromyography was recorded from neck flexor and extensor muscles during neck endurance tests. Time to task failure, amplitude and median frequency of the electromyography signal, and subjective fatigue and pain ratings were analysed in 50 patients who completed at least one follow-up. Results: A significant increase in neck flexor endurance time was observed for both groups at 14 weeks compared with baseline and this was maintained at the 12-month follow-up (pamp;lt;0.005). No change was identified for the slope of the median frequency. For the neck-specific training group, splenius capitis was less active during neck flexion at both follow-ups (pamp;lt;0.01), indicating reduced muscle co-activation. Conclusion: Both specific and general exercise increased neck flexor endurance, but neck-specific training only reduced co-activation of antagonist muscles during sustained neck flexion.

  • Balance problems and dizziness after neck surgery–associations with pain and health-related quality of life
  • 2019
  • Ingår i: Physiotherapy Theory and Practice. - 0959-3985.
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Symptoms of dizziness or imbalance are often present in individuals with a variety of neck-disorders. The aims of this study were to determine the prevalence of patient-reported balance problems and dizziness 10–13 years after surgery for cervical degenerative disc disease; evaluate associations with neck pain and health-related quality of life; and investigate how these individuals described dizziness. Material and methods: Sixty-eight individuals, 10 years or more after anterior cervical decompression and fusion surgery, who previously participated in a randomized controlled trial were included. Participants completed questionnaires including ratings of dizziness and balance problems, the Dizziness Handicap Inventory, and an open-ended question regarding their experience of dizziness. Secondary outcomes were neck pain and quality of life. Results: Seventy-two percent experienced occasional or daily symptoms of unsteadiness and/or dizziness. Intensity ratings for dizziness during movement and for balance problems were similar and rather low, but had an impact on quality of life. Ratings of dizziness at rest were even lower. Dizziness ratings were associated with neck pain. Strenuous activities were related to dizziness and dizziness was primarily described as intermittent and non-rotatory. Conclusions: Dizziness or balance problems in the long-term after surgery for cervical degenerative disc disease are common and have an impact on daily life. Ratings of problem frequency and intensity were usually low. Dizziness and balance problems may affect quality of life. Patients’ descriptions of these problems are in line with common symptoms of cervicogenic dizziness. © 2019, © 2019 The Author(s). Published by Taylor & Francis.

    • The objective of this study was to investigate the relationship between fat infiltration in the cervical multifidi and fat infiltration measured in the lower extremities to move further into understanding the complex signs and symptoms arising from a whiplash trauma. Thirty-one individuals with chronic whiplash associated disorders, stratified into a mild/moderate group and a severe group, together with 31 age- and gender matched controls were enrolled in this study. Magnetic resonance imaging was used to acquire a 3D volume of the neck and of the whole-body. Cervical multifidi was used to represent muscles local to the whiplash trauma and all muscles below the hip joint, the lower extremities, were representing widespread muscles distal to the site of the trauma. The fat infiltration was determined by fat fraction in the segmented images. There was a linear correlation between local and distal muscle fat infiltration (p<0.001, r2 = 0.28). The correlation remained significant when adjusting for age and WAD group (p = 0.009) as well as when correcting for age, WAD group and BMI (p = 0.002). There was a correlation between local and distal muscle fat infiltration within the severe WAD group (p = 0.0016, r2 = 0.69) and in the healthy group (p = 0.022, r2 = 0.17) but not in the mild/moderate group (p = 0.29, r2 = 0.06). No significant differences (p = 0.11) in the lower extremities' MFI between the different groups were found. The absence of differences between the groups in terms of lower extremities' muscle fat infiltration indicates that, in this particular population, the whiplash trauma has a local effect on muscle fat infiltration rather than a generalized.

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Fifty percent of people injured by whiplash still report neck pain after 1 year and costs associated with whiplash associated disorders (WAD) are mostly attributed to health service and sick-leave costs in chronic conditions. With increasing health care expenditures the economic impact of interventions needs to be considered.Objective: To analyze the cost-effectiveness of physiotherapist-led neck-specific exercise without (NSE) or with a behavioral approach (NSEB), or prescription of physical activity (PPA) in chronic WAD, grade 2 to 3.Methods: This is a secondary cost-effectiveness analysis of a multicenter randomized clinical trial of 216 participants with chronic WAD grade 2 to 3. The interventions were physiotherapist-led neck-specific exercise without or with a behavioral approach, or prescription of physical activity for 12 weeks. Incremental cost-effectiveness ratios (ICERs) were determined after 1 year and bootstrapped cost-effectiveness planes and sensitivity analyses of physiotherapy visits were performed. Health care and production loss costs were included and quality-adjusted life years (QALYs) were estimated, using the Euroqol-5D questionnaire. Comparisons with the Short Form-6D, and neck disability index (NDI) were also made.Results: The 1-year follow-up was completed by 170 participants (79%). Both physiotherapist-led groups improved in health related quality of life. The intervention cost alone, per quality-adjusted life year (QALY) gain in the NSE group was US$12,067. A trend for higher QALY gains were observed in the NSEB group but the costs were also higher. The ICERs varied depending on questionnaire used, but the addition of a behavioral approach to neck-specific exercise alone was not cost-effective from a societal perspective (ICER primary outcome $127,800 [95% confidence interval [CI], 37,816-711,302]). The sensitivity analyses confirmed the results. The prescription of physical activity did not result in any QALY gain and the societal costs were not lower.Conclusion: Neck-specific exercise was cost-effective from a societal perspective in the treatment of chronic WAD compared with the other exercise interventions. ICERS varied depending on health-related quality of life questionnaires used, but the addition of a behavioral approach was not cost-effective from a societal perspective. The prescription of physical activity did not result in any QALY gain and was thus not considered a relevant option.

    • Prognostic models play an important role in the clinical management of cervical radiculopathy (CR). No study has compared the performance of modern machine learning techniques, against more traditional stepwise regression techniques, when developing prognostic models in individuals with CR. We analysed a prospective cohort dataset of 201 individuals with CR. Four modelling techniques (stepwise regression, least absolute shrinkage and selection operator [LASSO], boosting, and multivariate adaptive regression splines [MuARS]) were each used to form a prognostic model for each of four outcomes obtained at a 12 month follow-up (disability-neck disability index [NDI]), quality of life (EQ5D), present neck pain intensity, and present arm pain intensity). For all four outcomes, the differences in mean performance between all four models were small (difference of NDI<1 point; EQ5D<0.1 point; neck and arm pain<2 points). Given that the predictive accuracy of all four modelling methods were clinically similar, the optimal modelling method may be selected based on the parsimony of predictors. Some of the most parsimonious models were achieved using MuARS, a non-linear technique. Modern machine learning methods may be used to probe relationships along different regions of the predictor space.

  • One- And Two-Year Follow-Up Of A Randomized Trial Of Neck Specific Exercise With Or Without A Behavioural Approach Compared With Prescription Of Physical Activity In Chronic Whiplash Disorder
  • 2016
  • Ingår i: ; 48:1, s. 56-64
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To explore whether neck-specific exercise, with or without a behavioural approach, has benefits after 1 and 2 years compared with prescribed physical activity regarding pain, self-rated functioning/disability, and self-efficacy in management of chronic whiplash. Design: Follow-up of a randomized, assessor blinded, clinical trial. Patients: A total of 216 volunteers with chronic whiplash associated disorders, grades 2 or 3. Methods: Participants were randomized to 1 of 3 exercise interventions: neck-specific exercise with or without a behavioural approach, or physical activity prescription. Self-rated pain (visual analogue scale), disability/functioning (Neck Disability Index/Patient Specific Functional Scale) and self-efficacy (Self-Efficacy Scale) were evaluated after 1 and 2 years. Results: Both neck-specific exercise groups maintained more improvement regarding disability/functioning than the prescribed physical activity group at both time-points (p <= 0.02). At 1 year, 61% of subjects in the neck-specific group reported at least 50% pain reduction, compared with 26% of those in the physical activity prescription group (p < 0.001), but at 2 years the difference was not significant. Conclusion: After 1-2 years, participants with chronic whiplash who were randomized to neck-specific exercise, with or without a behavioural approach, remained more improved than participants who were prescribed general physical activity.

  • The Effect of Neck-specific Exercise with, or without a Behavioral Approach, on Pain, Disability and Self-efficacy in Chronic Whiplash-associated Disorders : A Randomized Clinical Trial
  • 2015
  • Ingår i: The Clinical Journal of Pain. - : Lippincott, Williams andamp; Wilkins. - 0749-8047 .- 1536-5409. ; 31:4, s. 249-303

    • OBJECTIVES:: The aim of this study was to compare the effect on self-rated pain, disability and self-efficacy of three interventions for the management of chronic Whiplash Associated Disorders (WAD): physiotherapist-led neck-specific exercise, physiotherapist-led neck-specific exercise with the addition of a behavioral approach, or prescription of physical activity.METHODS:: Two hundred and sixteen volunteers with chronic WAD participated in this randomized, assessor blinded, clinical trial of three exercise interventions. Self-rated pain/pain bothersomeness (Visual Analogue Scale), disability (Neck Disability Index) and self-efficacy (Self-Efficacy Scale) were evaluated at baseline and at three and six months.RESULTS:: The proportion of patients reaching substantial reduction in pain bothersomness (at least 50% reduction) was more evident (P<0.01) in the two neck-specific exercise groups (29-48%) compared to the prescription of physical activity group (5%) at three months. At six months 39-44% of the patients in the two neck-specific groups and 28% in the prescription of physical activity group reported substantial pain reduction. Reduction of disability was also larger in the two neck-specific exercise groups at both three and six months (P<0.02). Self-efficacy was only improved in the neck-specific exercise group without a behavioral approach (P=0.02). However there were no significant differences in any outcomes between the two physiotherapist-led neck-specific exercise groups.DISCUSSION:: Neck-specific exercise resulted in superior outcomes compared to prescription of physical activity in this study, but the observed benefits of adding a behavioral approach to the implementation of exercise in this study were inconclusive.
