- We conducted a prospective randomized study to investigate predictive factors for short- and long-term outcome of anterior cervical decompression and fusion (ACDF) as measured by current pain intensity on the Visual Analogue Scale (VAS) and by disability using the Neck Disability Index (NDI). Current understanding about how preoperative and short-term outcome data predict long-term outcome is sparse, and there are few studies involving analysis of short-term follow-up using multivariate approaches with quantification of the relative importance of each variable studied. A total of 95 patients were randomly allocated for ACDF with the cervical intervertebral fusion cage or the Cloward procedure. The mean follow-up time was 19 months (range 12-24) for short-term follow-up and 76 months (range 56-94 months) for long-term. Background factors, radiologically detected findings, physiological measurements, treatment type, pain, and disability were used as potential predictors. Multivariate statistical analysis by projection to latent structures was used to investigate predictors of importance for short- and long-term outcome of ACDF. A "preoperative" low disability and pain intensity, non-smoking status, male sex, good hand strength, and an active range of motion (AROM) in the neck were significant predictors for good short- and long-term outcomes. The short-term outcome data were better at predicting long-term outcome than were baseline data. Radiologically detected findings and surgical technique used were mainly insignificant as predictors. We suggest that the inclusion criteria for ACDF should be based on a bio-psycho-social model including NDI. NDI may also be regarded as an important outcome measurement in evaluation of ACDF.

- 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

- OBJECTIVE: The aim of the study was to compare the dimensions of cervical multifidus muscle (CMM) in different conditions.METHODS: Twenty five women with neck pain and 25 healthy subjects participated in this study. The dimensions of the CMM were measured at rest, 50% and 100% maximum isometric voluntary contraction (MIVC) at six directions of neck movements, using ultrasonography.RESULTS: The size of multifidus was smaller in patients than healthy individuals at rest state (P < 0.05). A significant smaller CMM dimension was found in the affected side compared with unaffected side in patients group (P < 0.05). The result of ANOVA for MLD showed a significant difference for contraction levels (P < 0.001) and neck movements (P < 0.001) in both groups. The MLD of the CMM was significantly different between CMM at rest and 50%, and 100% MIVC (P < 0.001). No significant differences were found between the groups at 50% and 100% MIVC (P > 0.05 in both instances). The most prominent CMM size change was observed during neck extension, flexion, ipsilateral lateral-flexion, and ipsilateral rotation, respectively (P < 0.05).CONCLUSIONS: Results of the present study indicate that the size of CMM was decreased in patients with neck pain in rest state. The size of CMM changes in all directions of neck movements, although the most prominent was during neck extension. This points out CMM stabilization role's in different directions of neck movements.

Tidskriftsartikel (refereegranskat)abstract
- Building on a previous meta-analysis, this study focused on the utility of consolidating grip strength data from apparently healthy subjects 20-49 years of age. All data were obtained using a Jamar dynamometer and procedures generally consistent with the recommendations of the American Society of Hand Therapists. The meta-analysis revealed that the seven sources provided homogeneous data (Q = 0.21 -0.81, p ≥ 0.667) for the left and right sides of men and women subjects. Means and confidence intervals are provided that can be used to interpret the normality of grip strength obtained from men and women 20-49 years of age. By consolidating the data from multiple studies conducted in five countries, a better overall estimate of normal is obtained. Providing reference values for three decades combined simplifies normative comparisons.

- The purpose of this meta-analysis was to consolidate the results of studies presenting normative values for grip strength obtained with the Jamar dynamometer in accordance with the recommendations of the American Society of Hand Therapists. Relevant data from 12 sources (3317 subjects) were employed. Means and 95% confidence intervals are presented for the left and right sides of men and women in 12 age groups (20–24, 25–29, 30–34, 35–39, 40–44, 45–49, 50–54, 55–59, 60–64, 65–69, 70–74, 75+ years). The consolidated grip strength reference values offer a better standard for comparison than provided by any single study alone. Limitations in the meta-analysis notwithstanding, the lower limit of the 95% confidence interval can serve as a reasonable threshold for establishing grip strength impairment among adults.

- Neck disorders are common in primary health care (PHC) physiotherapy. A neck-specific exercise program based on research findings was implemented among physiotherapists in Swedish PHC. The aim of the study was to evaluate the adoption of the program. We invited PHC physiotherapists to an educational session including theoretical information and practical training. Before the educational session the participants (n = 261) completed a baseline questionnaire. After 3 and 12 months, we distributed surveys to identify changes in practice and in confidence regarding diagnosis and treatment. We compared data from 3-months and 12-months follow-up, respectively, with baseline data. Self-reported frequency of most of the included assessment methods was unchanged after 12 months. Frequency of assessment of neck proprioception had increased significantly. Specific neck muscle exercise for treatment of whiplash associated disorders was applied more frequently after 3 and after 12 months than at baseline. Frequency of other treatment methods remained unchanged. Confidence in diagnosis and treatment increased significantly, particularly among women. The program was not adopted as expected, but resulted in increased confidence regarding diagnosis and treatment. The provision of a short educational session seemed not to be sufficient to obtain a sustained change in practice.

- Background and aimsNeck pain can impair perception of cervical movement, but how this is affected by attention is unknown. In this study, the effects of experimental neck pain on head repositioning accuracy during standardized head movements were investigated.MethodsExperimental neck pain was induced by injecting hypertonic saline into the right splenius capitis muscle in 28 healthy participants (12 women). Isotonic saline was used as control. Participants were blindfolded while performing standardized head movements from neutral (start) to either right-rotation, left-rotation, flexion or extension, then back to neutral (end). Movements were triplicated for each direction, separated by 5-s, and performed with or without a cognitive task at baseline, immediately after the injection, and 5-min after pain disappeared. Repositioning accuracy was assessed by 3-dimensional recordings of head movement and defined as the difference between start and end position. Participants were grouped into most/least accurate based on a median split of head repositioning accuracy for each movement direction at baseline without the cognitive task.ResultsThe most accurate group got less accurate following hypertonic injection during right-rotation without a cognitive task, compared with the least accurate group and the isotonic condition (p < 0.01). No group difference was found when testing head repositioning accuracy while the participants where distracted by the cognitive task.ConclusionsExperimental neck pain alters head repositioning accuracy in healthy participants, but only in those who are most accurate at baseline. Interestingly, this impairment was no longer present when a cognitive task was added to the head repositioning accuracy test.ImplicationsThe results adds to our understanding of what factor may influence the head repositioning accuracy test when used in clinical practice and thereby how the results should be interpreted.

- Background: Musculoskeletal disorders (MSK) are a global burden causing significant suffering and economic impact. Systematic identification and targeting of research questions of highest interest for stakeholders can aid in improving MSK disorder knowledge and management.Objective: To obtain Swedish MSK researchers' opinions and views on a collaborative Swedish MSK network (SweMSK) and identify future research areas of importance for Swedish MSK research.Methods: A web-based survey was conducted July to September 2021 to collect data from 354 Swedish MSK researchers. The survey focused on the need, objectives, and structure of a SweMSK network and identified prioritised areas for future MSK research.Results: The study included 141 respondents, of which 82 were associate professors or professors. The majority (68%) supported the creation of a new musculoskeletal network. The most supported element was increased collaboration regarding nationwide and multicenter studies. Respondents recommended the creation of a homepage and the establishment of national work groups with different specific interests as the primary elements of a new network.Conclusion: The results demonstrated a need and desire for increased national research collaboration and the creation of a new musculoskeletal network. The high academic experience and active research participation of the respondents suggest the need for MSK disorder knowledge and management improvement in Sweden. Therefore, the SweMSK network may help facilitate effective collaboration and research efforts that can contribute to the advancement of MSK disorder management and care. This study may provide valuable insights for policymakers, clinicians, and researchers to improve MSK disorder care and management in Sweden.

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.

- Background: Dizziness is a common reason for seeking care, and frequently affects older persons. The aims were to determine the prevalence of dizziness in older persons at high risk of hospitalization, to compare subjects with and without dizziness, and to examine the effects on dizziness of a proactive primary care intervention in comparison with conventional care after one year.Methods: Data were derived from a prospective multicentre clinical trial in persons aged 75 and older and at high risk of hospitalization. A baseline questionnaire included demographic data, use of aids, questions about everyday physical activity and exercise, pain (intensity, frequency, and duration), activities of daily living measured using the ADL Staircase, and health-related quality of life measured using the EQ-5D-3L vertical visual analogue scale. Both at baseline and after one year, subjects were asked about dizziness, and those with dizziness answered the Dizziness Handicap Inventory - Screening version. Subjects in the intervention group were evaluated by a primary care team and when needed proactive care plans were established. Groups were compared using the Mann Whitney U-test or chi-squared test.Results: Of the 779 subjects, 493 (63%) experienced dizziness. Persons with dizziness differed regarding sex, homecare service, aids, activities of daily living, health-related quality of life, physical activity, and pain. The intervention did not significantly reduce the level of dizziness.Conclusions: Dizziness is common in vulnerable older persons, and individuals with dizziness differ in several respects. Further studies are needed employing more dizziness-specific assessment and individually tailored interventions.
