- Previous studies have shown altered neck muscle function in individuals with chronic whiplash associated disorder (WAD). However, we lack real-time investigations with non-invasive methods that can distinguish between the different ventral neck muscle layers. This study investigated deformations and deformation rates in the sternocleidomastoid (SCM), longus capitis (Lcap), and longus colli (Lco) muscles with real-time ultrasonography. Twenty-six individuals with WAD were compared with 26 controls, matched for age and sex. Ultrasound imaging of the SCM, Lcap, and Lco were recorded during 10 repetitive arm elevations. The first and tenth arm elevations were post-process analyzed with speckle tracking. There were few significant differences in the deformations or deformation rates in the SCM, Lcap, and Lco between the WAD and control group. In controls, deformations and deformation rates showed linear positive relationships between SCM/Lcap, SCM/Lco, and Lcap/Lco which increased from the first arm elevation (R-2 = 0.14-0.70); to the tenth arm elevation (R-2 = 0.51-0.71). The WAD group showed similar or weaker linear relationship (R-2 < 0.19) during the tenth compared to the first (R-2 < 0.44) arm elevation except for deformations in Lcap/Lco (R-2 = 0.13-0.57). This result indicated that deformations and deformation rates in one muscle were correlated by similar deformations and deformation rates in other neck muscles in the control group, but this interplay between muscles was not found in the WAD group.

- BackgroundNo previous studies have investigated what biopsychosocial factors are associated with self‐reported work ability in conservatively managed patients with cervical radiculopathy.ObjectiveTo develop a theoretical model of factors and potential processes associated with variation in work ability based on a thorough assessment of biopsychosocial variables in conservatively managed patients with cervical radiculopathy.DesignCross‐sectional observational study.SettingTertiary neurosurgery clinic.PatientsA total of 144 conservatively managed patients with cervical pain and radiculopathy participated in the study.MethodsFrom 64 biopsychosocial candidate variables, significant (P < .05) bivariate correlators with Work Ability Index (WAI) were entered as independent variables in a categorical regression. Elastic net regularization maintained the most parsimonious set of independent variables significantly associated with variation in WAI as the dependent variable. Process analysis of significant independent variable associations with WAI was performed.Main Outcome MeasurementWAI.ResultsFrom 42 bivariate correlates of WAI, multivariate regression displayed a total of seven variables that were significantly (F [25,98] = 5.74, P < .05) associated with 65.8% of the variation in WAI. The Neck Disability Index (NDI) and Fear‐Avoidance Beliefs Questionnaire Work subscale (FABQ‐W) were significant individual factors within the final regression model. Process analysis displayed FABQ‐W having a significant specific indirect association with the direct association between NDI and WAI, with the model associated with 77% of the variability in WAI (F [2,84] = 141.17, P < .001).ConclusionOf 64 candidate biopsychosocial factors, NDI and FABQ‐W were the most significant multivariate correlates with work ability. FABQ‐W has a significant indirect association with baseline NDI scores and perceived work ability. This warrants future research trialing work‐related fear avoidance interventions in conservatively managed patients with cervical radiculopathy.Level of EvidenceIII

- Background: Patients with cervical radiculopathy often have neck- and arm pain, neurological changes, activity limitations and difficulties in returning to work. Most patients are not candidates for surgery but are often treated with different conservative approaches and may be sick-listed for long periods. The purpose of the current study is to compare the effectiveness of neck- specific training versus prescribed physical activity. Methods/Design: The current protocol is a two armed intervention randomised clinical trial comparing the outcomes of patients receiving neck specific training or prescribed physical activity. A total of 144 patients with cervical radiculopathy will be randomly allocated to either of the two interventions. The interventions will be delivered by experienced physiotherapists and last 14 weeks. The primary outcome variable is neck- and arm pain intensity measured with a Visual Analogue Scale accompanied with secondary outcome measures of impairments and subjective health measurements collected before intervention and at 3, 6, 12 and 24 months after base-line assessment. Discussion: We anticipate that the results of this study will provide evidence to support recommendations as to the effectiveness of conservative interventions for patients with cervical radiculopathy.

- PurposeThe aim of the study was to compare myoelectric manifestation in neck muscle endurance and fatigue characteristics during sub-maximal isometric endurance test in patients with cervical radiculopathy and asymptomatic subjects. An additional aim was to explore associations between primary neck muscle endurance, myoelectric fatigability, and self-rated levels of fatigue, pain and subjective health measurements in patients with cervical radiculopathy.MethodsMuscle fatigue in the ventral and dorsal neck muscles was assessed in patients with cervical radiculopathy and in an asymptomatic group during an isometric neck muscle endurance test in prone and supine. 46 patients and 34 asymptomatic subjects participated. Surface electromyography signals were recorded from the sternocleidomastoid, cervical paraspinal muscles and upper and middle trapezius bilaterally during the endurance test. Subjective health measurements were assessed with questionnaires.ResultsThe results showed altered neck muscle endurance in several of the muscles investigated with greater negative median frequency slope, greater variability, side imbalance, lower endurance time and higher experience of fatigue among the cervical radiculopathy patients compared with healthy subjects. Endurance times were significantly lower in both prone and in supine positions between the patients compared to asymptomatic subjects. During the neck muscle endurance test, fatigues in the upper trapezius muscles during the prone test and in the sternocleidomastoid muscles during the supine test were of more importance than self-perceived pain, fatigue, disability and kinesiophobia in predicting neck muscle endurance (NME).ConclusionNME testing in the primary neck muscles seems to be an important factor to take into consideration in rehabilitation.

- INTRODUCTION: Neck muscle function is important for support and control of the cervical spine. With the application of frequency analysis of the electromyography (EMG) signal, the fatigue rate of muscles can be monitored. In several EMG studies, the neck muscles have been shown to fatigue faster in subjects with neck pain. This can be seen when the median frequency (MF) decreases when a contraction is sustained.AIM: In this experimental study the purpose was to evaluate patients with cervical radiculopathy compared to healthy subjects regarding changes in neckZmuscle fatigue during static endurance test in prone and supine.METHODS: A total of 33 patients (19 women and 14 men) with cervical radiculopathy and 28 healthy subjects (17 women and 11 men) were included in the study. Neck muscle fatigue was studied using EMG with surface electrodes bilaterally on cervical paraspinal and sternocleidomastoid muscle groups with electrode placement according to SENIAM. Measurements of neck muscle fatigue were performed in supine and prone positions until patient perceived time till exhaustion. Subjective neck muscle fatigue was rated on a Borg CRZ10 scale while subjective neck pain was measured on 0Z10 Visual analogue scale (VAS). Patients with cervical radiculopathy even completed the Neck Disability Index (NDI).RESULTS: The mean endurance time during static extension between groups was significantly different (p<0.001) with cervical radiculopathy patients recording 190 seconds (Sd=119) and the healthy subjects 509 seconds (Sd=213). Differences in mean endurance time during static flexion between groups were nonZsignificant with cervical radiculopathy patients recording 64 seconds (Sd=40) and the healthy subjects 96 seconds (Sd=69). Cervical radiculopathy patients MF EMG slope (Z0.039) for the right cervical paraspinal muscles significantly decreased (p=0.009) more the healthy subjects (Z0.017) during the extension test. NDI significantly correlated with MF EMG slope for both left (r=Z0.631 p= 0.001) and right side (r=Z0Z496 p=0.014) cervical paraspinal muscles during extension for the patient group.CONCLUSION: Patients with cervical radiculopathy perform similar to healthy subjects with regards to static supine flexion endurance time and cervical muscle fatigue. Patients with cervical radiculopathy however have significantly lower endurance times and fatigue faster in the right side cervical paraspinal muscles during static prone extension.ACKNOWLEDGEMENT: The authors declare no conflicts of interest.

- Background Dizziness and balance problems are common symptoms in patients with cervical radiculopathy. Objective To evaluate the effect of neck surgery postoperatively combined with either structured rehabilitation or standard approach in patients with cervical radiculopathy and dizziness and/or balance problems, and investigate factors influencing dizziness and balance at 6-month follow-up.Methods Individuals (n = 149) with cervical radiculopathy and dizziness and/or balance problems were randomized preoperatively to structured postoperative rehabilitation or standard postoperative approach. Outcomes were intensity of dizziness and subjective balance, and clinical measures of balance.Results Self-reported measures improved at three months (p < 0.001 to p = .007) and the standing balance at six months (p = .008). No between-group differences. Baseline values, neck pain, and physical activity level explained 23-39% of the variance in 6-month outcomes for self-reported measures. Baseline values and physical activity level explained 71% of the variance in walking balance, and lower baseline scores were significantly associated with standing balance impairments (OR 0.876).Conclusion Patients improved significantly in dizziness and subjective balance intensity shortly after surgery, and in standing balance at 6 months, independent of postoperative rehabilitation. Neck pain, physical activity, and neck muscle function influenced dizziness and balance, although preoperative values and neck pain were of most importance for 6-month outcomes.

- Pain as a result of cervical radiculopathy (CR) can be widespread, nondermatomal and individually specific, but the association between pain extent and other clinical features has never been explored. The objective of this study is to investigate whether pain extent relates to clinical variables including pain intensity in addition to health indicators including disability, general health, depression, somatic anxiety, coping strategies or self-efficacy. An observational cohort study was conducted. Participants were recruited from 4 hospital spinal centres in Sweden. Pain extent was quantified from the pain drawings of 190 individuals with cervical disc disease, verified with magnetic resonance imaging (MRI) and compatible with clinical findings (examined by a neurosurgeon), that show cervical nerve root compression. Pain extent was evaluated in relation to neck pain, arm pain, and headache intensity. Multiple linear regression analysis were then used to verify whether pain extent was associated with other health indicators including disability, health-related quality of life, depression, somatic anxiety, coping strategies and self-efficacy. Pain extent was directly related to neck, arm and headache pain intensity (all P < .01). Multiple linear regression revealed that pain extent was significantly associated only to the level of perceived disability (P < .01). Increased pain extent in people with CR is associated with higher headache, neck and arm pain intensity, and disability but not measures of general health, depression, somatic anxiety, coping strategies or self-efficacy.

- Background: Establishing a set of uniform classification criteria (CC) for cervical radiculopathy (CR) is required to aid future recruitment of homogenous populations to clinical trials.Objectives: To establish expert informed consensus on CC for CR.Design: A pre-defined four round e-Delphi study in accordance with the guidance on Conducting and Reporting Delphi Studies.Methods: Individuals with a background in physiotherapy who had authored two or more peer-reviewed publications on CR were invited to participate. The initial round asked opinions on CC for CR. Content analysis was performed on round one output and a list of discrete items generated forming the round two survey. In rounds two to four, participants were asked to rate the level of importance of each item on a six-point Likert scale. Data were analysed descriptively using median, interquartile range and percentage agreement. Items reaching pre-defined consensus criteria were carried forward to the next round. Items remaining after the fourth round constituted expert consensus on CC for CR.Results: Twelve participants participated with one drop out. The final round identified one inclusion CC and 12 exclusion CC. The inclusion CC that remained achieved 82% agreement and was a cluster criterion consisting of radicular pain with arm pain worse than neck pain; paraesthesia or numbness and/or weakness and/or altered reflex; MRI confirmed nerve root compression compatible with clinical finding.Conclusions: The CC identified can be used to inform eligibility criteria for future CR trials although caution should be practiced as consensus on measurement tools requires further investigation.

- 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.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Although 50% of those who suffer a whiplash injury still report neck pain after one year, there is a lack of knowledge about effective treatment for chronic whiplash associated disorders (WAD). Exercise is potentially useful, but the response to exercise in chronic WAD is highly variable between individuals and factors associated with good outcomes as well as the cost-effectiveness are unknown.Aim: The general aim of this thesis was to evaluate the effect on self-reported disability/ functioning, pain and selfefficacy of three different exercise interventions in chronic WAD grade 2 and 3, and to determine the cost-effectiveness of these interventions.Material and methods: A total of 216 participants with chronic WAD took part in this randomized, assessor blinded, controlled, clinical trial. Participants were randomized to either neck-specific exercise without (NSE), or with a behavioural approach (NSEB), or prescription of physical activity (PPA) for 12 weeks. Evaluations of change scores and proportion of clinically relevantly improved participants regarding disability/functioning (Neck Disability Index (NDI)/Patient Specific Functional Scale (PSFS)), pain (Visual Analogue Scale of current neck pain (VAS-P), pain bothersomeness (VAS-B)) and Self-efficacy (Self-Efficacy Scale (SES)) were made after 3, 6, 12 and 24 months. Secondary analyses were made, regarding factors associated with clinically relevant improvements in disability, pain and regarding cost-effectiveness.Results: Disability was more improved in the NSE/NSEB groups (NDI, P=0.02) than the PPA group, which reported no improvement, at 3 and 6 months, results remaining at 12 and 24 months (p ≤ 0.02). Functioning (PSFS) was also more improved in the NSE/NSEB groups than the PPA group at 3 months, in the NSEB compared to the PPA group at 6 months, and the NSE compared to the PPA groups at 12 and 24 months. The proportion of participants reaching clinically relevant improvement regarding NDI and PSFS was also larger in the NSE/NSEB groups at all time points (P<0.05), except NDI at 3 months and PSFS at 24 months. There were no differences between groups in VAS-P, VASB or SES change scores. The proportion of participants with clinically relevant reduction in VAS-P and VAS-B was however higher (P<0.02) in the NSE/NSEB groups compared with the PPA group at 3 and 12 months. Self-efficacy was only improved in the NSE group but without any between-group differences. There were no significant differences in any outcomes between the NSE/NSEB groups.The only significant factor associated with both clinically relevant improvements in disability and neck pain both at 3 and 12 months was participation in the NSE group, with odds up to 5.3 times higher than in the PPA group. Different baseline features were associated with the improvements depending on the outcome and time point examined. From a societal perspective, NSE was the cost-effective option.Conclusion: Physiotherapist-led neck-specific exercise resulted in better outcomes than prescription of physical activity regarding disability, functioning, and pain. The observed benefits of adding a behavioural approach to neck-specific exercise were inconclusive, and NSE was the cost-effective option from a societal perspective. Factors associated with clinically relevant improvements after exercise interventions in chronic WAD differed whether disability or neck pain was the outcome, but also differed in the short and long term. Participation in the NSE group was the only factor associated with both outcomes after both 3 and 12 months.
