Variability of Active Cervical Range of Motion Within and Between Days in Healthy Participants: A Prospective Observational Study.

OBJECTIVE: The purpose of this study was to determine the intraday and interday variability and systematic change over the day of active cervical range of motion (aCROM) measurements in asymptomatic persons using a clinically applicable measurement device. METHODS: A prospective observational study was performed. Sixteen adults (8 men and 8 women, median age 51 years) without neck pain in the last 3 months were recruited in 2 physiotherapy practices. Active cervical range of motion was estimated using the Apple iPhone application "3D Range of Motion." Measurements were performed 3 times a day for 7 days and spread over a period of 3 weeks. Mean values of aCROM were calculated. Intraday and interday variability was estimated by calculating limits of agreement. RESULTS: The limits of agreement for intraday variability ranged from ±12.1° for left rotation to ±15.5° for total rotation. For interday variability, the limits of agreement ranged from ±14.2° for right rotation to ±20.1° for total rotation. No systematic change over the day was found. CONCLUSION: This study showed substantial intraday and interday variability of aCROM measurements in asymptomatic people. No trend toward an increased or decreased aCROM was observed during the course of the day. When interpreting aCROM values, clinicians should consider the degree of variation in aCROM measurements over time.

The Effect of a Personalized Newsletter to Physical Therapists on Patient Recruitment: A Cluster Randomized Trial in Primary Physiotherapy Care.

OBJECTIVE: To assess the effect of a personalized newsletter compared with a standard newsletter on patient recruitment in physiotherapy research. METHODS: We performed a cluster-randomized trial including 120 physiotherapists who recruited patients for a prospective cohort and were randomly assigned to either receiving personalized feedback in a newsletter (intervention group) or a standard newsletter (control group). We calculated the difference in the number of patients included in the study corrected for inclusion time between both groups. RESULTS: The physiotherapists in the control group (n = 59) included 110 patients (35.4% of the total number of patients included) compared with an inclusion of 200 patients (64.6% of the total number of patients included) by the physiotherapists in the intervention group (n = 61), a difference of 90 patients in favor of the intervention group. However, when corrected for inclusion time and a cluster effect, we found no statistically significant difference between both groups. In addition, therapists who did not include a single patient (inactive therapists) were evenly divided between the 2 groups (n = 29 [49%] in the control group; n = 30 [49%] in the intervention group). CONCLUSIONS: A personalized newsletter does not significantly increase the number of recruited patients by physiotherapists. However, therapists receiving personalized feedback recruited nearly double the number of patients compared with the ones receiving standard feedback.

Translation of the eHealth Impact Questionnaire for a Population of Dutch Electronic Health Users: Validation Study.

BACKGROUND: The eHealth Impact Questionnaire (eHIQ) provides a standardized method to measure attitudes of electronic health (eHealth) users toward eHealth. It has previously been validated in a population of eHealth users in the United Kingdom and consists of 2 parts and 5 subscales. Part 1 measures attitudes toward eHealth in general and consists of the subscales attitudes towards online health information (5 items) and attitudes towards sharing health experiences online (6 items). Part 2 measures the attitude toward a particular eHealth application and consists of the subscales confidence and identification (9 items), information and presentation (8 items), and understand and motivation (9 items). OBJECTIVE: This study aimed to translate and validate the eHIQ in a Dutch population of eHealth users. METHODS: The eHIQ was translated and validated in accordance with the COnsensus-based Standards for the selection of health status Measurement INstruments criteria. The validation comprised 3 study samples, with a total of 1287 participants. Structural validity was assessed using confirmatory factor analyses and exploratory factor analyses (EFAs; all 3 samples). Internal consistency was assessed using hierarchical omega (all 3 samples). Test-retest reliability was assessed after 2 weeks, using 2-way intraclass correlation coefficients (sample 1). Measurement error was assessed by calculating the smallest detectable change (sample 1). Convergent and divergent validity were assessed using correlations with the remaining measures (all 3 samples). A graded response model was fit, and item information curves were plotted to describe the information provided by items across item trait levels (all 3 samples). RESULTS: The original factor structure showed a bad fit in all 3 study samples. EFAs showed a good fit for a modified factor structure in the first study sample. This factor structure was subsequently tested in samples 2 and 3 and showed acceptable to good fits. Internal consistency, test-retest reliability, convergent validity, and divergent validity were acceptable to good for both the original as the modified factor structure, except for test-retest reliability of one of the original subscales and the 2 derivative subscales in the modified factor structure. The graded response model showed that some items underperformed in both the original and modified factor structure. CONCLUSIONS: The Dutch version of the eHIQ (eHIQ-NL) shows a different factor structure compared with the original English version. Part 1 of the eHIQ-NL consists of 3 subscales: attitudes towards online health information (5 items), comfort with sharing health experiences online (3 items), and usefulness of sharing health experiences online (3 items). Part 2 of the eHIQ-NL consists of 3 subscales: motivation and confidence to act (10 items), information and presentation (13 items), and identification (3 items).

Clinical course and prognostic models for the conservative management of cervical radiculopathy: a prospective cohort study.

PURPOSE: To describe the clinical course and develop prognostic models for poor recovery in patients with cervical radiculopathy who are managed conservatively. METHODS: Sixty-one consecutive adults with cervical radiculopathy who were referred for conservative management were included in a prospective cohort study, with 6- and 12-month follow-up assessments. Exclusion criteria were the presence of known serious pathology or spinal surgery in the past. Outcome measures were perceived recovery, neck pain intensity and disability level. Multiple imputation analyses were performed for missing values. Prognostic models were developed using multivariable logistic regression analyses, with bootstrapping techniques for internal validation. RESULTS: About 55% of participants reported to be recovered at 6 and 12 months. All multivariable models contained 2 baseline predictors. Longer symptoms duration increased the risk of poor perceived recovery, whereas the presence of paresthesia decreased this risk. A higher neck pain intensity and a longer duration of symptoms increased the risk of poor relief of neck pain. A higher disability score increased the risk of poor relief of disability, and larger active range of rotation toward the affected side decreased this risk. Following bootstrapping, the explained variance of the models varied between 0.22 and 0.30, and the median area under the curve varied between 0.75 and 0.79. CONCLUSIONS: The clinical course of cervical radiculopathy appears to be long, with most of the reduction in symptoms occurring within the first 6 months. All prognostic models showed an adequate predictive performance with modest diagnostic accuracy and explained variance. These slides can be retrieved under Electronic Supplementary Material.

Risk models for lower extremity injuries among short- and long distance runners: A prospective cohort study.

BACKGROUND: Running injuries are very common. Risk factors for running injuries are not consistently described across studies and do not differentiate between runners of long- and short distances within one cohort. OBJECTIVES: The aim of this study is to determine risk factors for running injuries in recreational long- and short distance runners separately. DESIGN: A prospective cohort study. METHODS: Recreational runners from four different running events are invited to participate. They filled in a baseline questionnaire assessing possible risk factors about 4 weeks before the run and one a week after the run assessing running injuries. Using logistic regression we developed an overall risk model and separate risk models based on the running distance. RESULTS: In total 3768 runners participated in this study. The overall risk model contained 4 risk factors: previous injuries (OR 3.7) and running distance during the event (OR 1.3) increased the risk of a running injury whereas older age (OR 0.99) and more training kilometers per week (OR 0.99) showed a decrease. Models between short- and long distance runners did not differ significantly. Previous injuries increased the risk of a running injury in all models, while more training kilometers per week decreased this risk. CONCLUSIONS: We found that risk factors for running injuries were not related to running distances. Previous injury is a generic risk factor for running injuries, as is weekly training distance. Prevention of running injuries is important and a higher weekly training volume seems to prevent injuries to a certain extent.

Concurrent validity and interrater reliability of a new smartphone application to assess 3D active cervical range of motion in patients with neck pain.

BACKGROUND: There is a lack of valid, reliable, and feasible instruments for measuring planar active cervical range of motion (aCROM) and associated 3D coupling motions in patients with neck pain. Smartphones have advanced sensors and appear to be suitable for these measurements. OBJECTIVES: To estimate the concurrent validity and interrater reliability of a new iPhone application for assessing planar aCROM and associated 3D coupling motions in patients with neck pain, using an electromagnetic tracking device as a reference test. DESIGN: Cross-sectional study. METHODS: Two samples of neck pain patients were recruited; 30 patients for the validity study and 26 patients for the reliability study. Validity was estimated using intraclass correlation coefficients (ICCs), and by calculating 95% limits of agreement (LoA). To estimate interrater reliability, ICCs were calculated. Cervical 3D coupling motions were analyzed by calculating the cross-correlation coefficients and ratio between the main motions and coupled motions for both instruments. RESULTS: ICCs for concurrent validity and interrater reliability ranged from 0.90 to 0.99. The width of the 95% LoA ranged from about 5° for right lateral bending to 11° for total rotation. No significant differences were found between both devices for associated coupling motion analysis. CONCLUSIONS: The iPhone application appears to be a useful discriminative tool for the measurement of planar aCROM and associated coupling motions in patients with neck pain. It fulfills the need for a valid, reliable, and feasible instrument in clinical practice and research. Therapists and researchers should consider measurement error when interpreting scores.

Considerations to improve the safety of cervical spine manual therapy.

Manipulation and mobilisation of the cervical spine are well established interventions in the management of patients with headache and/or neck pain. However, their benefits are accompanied by potential, yet rare risks in terms of serious adverse events, including neurovascular insult to the brain. A recent international framework for risk assessment and management offers directions in the mitigation of this risk by facilitating sound clinical reasoning. The aim of this article is to critically reflect on and summarize the current knowledge about cervical spine manual therapy and to provide guidance for clinical reasoning for cervical spine manual therapy.

Development of a Prognostic Model for Patients With Shoulder Complaints in Physical Therapist Practice.

Background: Health care providers need prognostic factors to distinguish between patients who are likely to recover and those who are not likely to recover. Objective: The aim of this study was to: (1) describe the clinical course of recovery and (2) identify prognostic factors of recovery in patients with shoulder pain at the 26-week follow-up. Design: A prospective cohort study was carried out in the Netherlands and included 389 patients who consulted a physical therapist for a new episode of shoulder pain. Method: Participants were followed for 26 weeks. Potential predictors of recovery were selected from the literature and, with the addition of 2 new variables (ie, use of diagnostic ultrasound and working alliance), evaluated in the multivariable regression analysis. Multiple imputation was used to handle missing data, and bootstrap methods were used for internal validation. Results: The recovery rate was 60% for the total population and 65% for the working population after 26 weeks. Short duration of complaints, lower disability scores, having a paid job, better working alliance, and no feelings of anxiety or depression were associated with recovery. In the working population, only duration of complaints and disability remained in the final model. The area under the receiver operating characteristic curve (AUC) for the final model was 0.67 for the total population and 0.63 for the working population. After internal validation, the AUC was corrected to 0.66 and 0.63, respectively. Limitations: External validation of the prognostic model should be done prior to its use in clinical practice. Conclusion: The results of this study indicate that several factors can predict recovery.

Support and preferences for intermediate health care services for back and neck pain: a survey among members of the Dutch patient association for spinal pain.

RATIONALE, AIMS AND OBJECTIVES: Recent health care reforms in the Netherlands have led to the introduction of intermediate health care. Intermediate health care combines features of primary care and secondary (hospital) care. It is characterized by a task shift from hospital care to primary care. The initial experiences of medical specialists and general practitioners with intermediate health care are positive. However, the patients' perspectives regarding this reform are unknown. This study aimed to evaluate the level of support from patients with back and/or neck pain for intermediate health care services and to provide insight into their preferences how this care should be organized. METHODS: A cross-sectional survey was conducted in which members of the patient association for spinal pain in the Netherlands completed electronic questionnaires to measure the level of support and preferred organization of intermediate health care services. RESULTS: Questionnaires were returned by 367 patients (response rate: 51%). Respondents supported the concept of intermediate health care (numeric rating scale: 7/10). Aspects considered important for intermediate health care included knowledge and expertise of staff, multidisciplinary cooperation, patient contact time, reimbursement via health insurance, quality control of care, evidence-based treatments and electronic medical records. Although intermediate care is a health care reform, patients continued to think according to traditional primary and secondary care constitutions. CONCLUSIONS: Patients with neck and/or back pain support the introduction of intermediate health care services and have explicit preferences regarding its organization, but may need to be better informed when intermediate care is introduced.

Validity of the Thessaly test in evaluating meniscal tears compared with arthroscopy: a diagnostic accuracy study.

STUDY DESIGN: Diagnostic accuracy study. OBJECTIVE: To evaluate the diagnostic accuracy of the Thessaly test compared with an arthroscopic examination in patients with suspected meniscal tears. BACKGROUND: The Thessaly test was introduced to improve the diagnostic accuracy of the clinical examination in detecting meniscal tears. This test appears to be a valuable alternative to other meniscal clinical tests usually performed, but additional diagnostic accuracy data are required. METHODS: Patients with suspected meniscal tears, referred to a hospital for arthroscopic surgery, were eligible. The Thessaly test alone and the combination of the Thessaly and McMurray tests were considered as index tests, and arthroscopy was used as the reference test. Experienced physical therapists performed the Thessaly test at 20° of flexion and the McMurray test for both knees. The physical therapist was blinded to patient information, the affected knee, and the results from possible earlier diagnostic imaging. An orthopaedic surgeon blinded to the clinical test results from the physical therapist performed the arthroscopic examination. RESULTS: A total of 593 patients were included, of whom 493 (83%) had a meniscal tear, as determined by the arthroscopic examination. The Thessaly test had a sensitivity of 64% (95% confidence interval [CI]: 60%, 68%), specificity of 53% (95% CI: 43%, 63%), positive predictive value of 87% (95% CI: 83%, 90%), negative predictive value of 23% (95% CI: 18%, 29%), and positive and negative likelihood ratios of 1.37 (95% CI: 1.10, 1.70) and 0.68 (95% CI: 0.59, 0.78), respectively. The combination of positive Thessaly and McMurray tests showed a sensitivity of 53% and specificity of 62%. CONCLUSION: The results of the Thessaly test alone or combined with the McMurray test do not seem useful to determine the presence or absence of meniscal tears. LEVEL OF EVIDENCE: Diagnosis, level 2b.

The Dutch Shoulder Pain and Disability Index (SPADI): a reliability and validation study.

PURPOSE: To evaluate the reliability and validity of the Dutch Shoulder Pain and Disability Index (SPADI-D). BACKGROUND: The SPADI is recommended and frequently used. However, the validity and reliability of the SPADI-D are unknown. METHODS: The study population consisted of patients consulting a physical therapist for shoulder pain. We assessed construct validity, using known groups, convergent validity (SDQ) and divergent validity (EQ5D) for which the mean difference or Spearman correlations coefficients were calculated. The factor structure was assessed using principal component factor analysis, and we calculated Cronbach's alpha and the ICC to assess the reliability. RESULTS: A total of 356 patients and a randomly selected group of 74 subjects for the reliability analysis were included. There was a significant difference between extreme groups (a high/low level of pain and work absence/presence) in SPADI score. The correlation between the SPADI and the SDQ was 0.69, with the EQ5D mobility-item 0.25 and with the depression-item 0.14. The SPADI consisted of one factor according to principal component factor analysis, which showed high internal consistency (Cronbach's alpha = 0.94 for the total score), and the test-retest reliability was good (ICC = 0.89). CONCLUSION: The Dutch SPADI is a valid and reliable questionnaire for patients in primary care in assessing functional disability.

The opinion and experiences of Dutch orthopedic surgeons and radiologists about diagnostic musculoskeletal ultrasound imaging in primary care: a survey.

INTRODUCTION AND AIM: The use of diagnostic musculoskeletal ultrasound (DMUS) in primary health care has increased in the recent years. Nevertheless, there are hardly any data concerning the reliability, accuracy and treatment consequences of DMUS used by physical therapists or general practitioners. Moreover, there are no papers published about how orthopedic surgeons or radiologists deal with the results of DMUS performed in primary care. Therefore, our aim is to evaluate the opinion, possible advantages or disadvantages and experiences of Dutch orthopedic surgeons and radiologists about DMUS in primary care. METHODS: A cross-sectional survey in which respondents completed a self-developed questionnaire to determine their opinion, experiences, advantages, disadvantages of performing DMUS in primary care. RESULTS: Questionnaires were sent to 838 Dutch orthopedic surgeons and radiologists of which 213 were returned (response rate 25.4%). Our respondents saw no additional value for health care for diagnostic DMUS in primary care. DMUSs were generally repeated in secondary care. They perceived more disadvantages than advantages of performing DMUS in primary care. Mentioned disadvantages were: 'false positive results' (71.4%), 'lack of experience' (70%), 'insufficient education' (69.5%), not able to relate the outcomes of DMUS with other forms of diagnostic imaging' (65.7%), and 'false negative results' (65.3%). CONCLUSION: Radiologists and orthopedic surgeons sampled in the Netherlands show low trust in DMUS knowledge of physical therapists and general practitioners. The results should be interpreted with caution because of the small response rate and the lack of representativeness to other countries.

Diagnostic accuracy of upper cervical spine instability tests: a systematic review.

BACKGROUND: Patients with neck pain, headache, torticollis, or neurological signs should be screened carefully for upper cervical spine instability, as these conditions are "red flags" for applying physical therapy interventions. However, little is known about the diagnostic accuracy of upper cervical spine instability tests. PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of upper cervical spine instability screening tests in patients or people who are healthy. DATA SOURCES: PubMed, CINAHL, EMBASE, and RECAL Legacy databases were searched from their inception through October 2012. STUDY SELECTION: Studies were included that assessed the diagnostic accuracy of upper cervical instability screening tests in patients or people who are healthy and in which sensitivity and specificity were reported or could be calculated using a 2 × 2 table. DATA EXTRACTION AND QUALITY ASSESSMENT: Two reviewers independently performed data extraction and the methodological quality assessment using the QUADAS-2. DATA SYNTHESIS: Depending on heterogeneity, statistical pooling was performed. All diagnostic parameters (sensitivity, specificity, predictive values, and likelihood ratios) were recalculated, if possible. RESULTS: Five studies were included in this systematic review. Statistical pooling was not possible due to clinical and statistical heterogeneity. Specificity of 7 tests was sufficient, but sensitivity varied. Predictive values were variable. Likelihood ratios also were variable, and, in most cases, the confidence intervals were large. LIMITATIONS: The included studies suffered from several biases. None of the studies evaluated upper cervical spine instability tests in patients receiving primary care. CONCLUSIONS: The membranes tests had the best diagnostic accuracy, but their applicability as a test for diagnosing upper cervical spine instability in primary care has yet to be confirmed.

Diagnostic accuracy of premanipulative vertebrobasilar insufficiency tests: a systematic review.

STUDY DESIGN: A systematic review of diagnostic accuracy studies. OBJECTIVE: To evaluate the diagnostic accuracy of the premanipulative vertebrobasilar insufficiency (VBI) tests. SUMMARY OF BACKGROUND DATA: The aim of premanipulative vertebrobasilar testing is to evaluate the adequacy of blood supply to the brain, by compressing the vertebral artery and examining for the onset of signs and symptoms of cerebrovascular ischemia. Although clinicians consider pre-manipulative testing important before applying spinal manipulations, the diagnostic accuracy has not been systematically reviewed. METHODS: A search was made in PUBMED, CINAHL and EMBASE databases from their date of inception until 2nd May 2012. Studies were included if they compared a VBI test with a reference test, and sensitivity and specificity were reported or could be calculated. The methodological quality of the studies was evaluated using QUADAS. Agreement between reviewers was calculated and expressed as a percentage and quantified by kappa statistics. RESULTS: Of the 1677 potential citations only 4 studies were included, all of questionable quality. Sensitivity was low and ranged from 0 to 57%, specificity from 67 to 100%, positive predictive value from 0% to 100%, and negative predictive value from 26 to 96%. The positive likelihood ratio ranged from 0.22 to 83.25 and the negative likelihood ratio from 0.44 to 1.40. CONCLUSION: Based on this systematic review of only 4 studies it was not possible to draw firm conclusions about the diagnostic accuracy of premanipulative tests. However, data on diagnostic accuracy indicate that the premanipulative tests do not seem valid in the premanipulative screening procedure. A surplus value for premanipulative tests seems unlikely.

Attitude, knowledge and behaviour towards evidence-based medicine of physical therapists, students, teachers and supervisors in the Netherlands: a survey.

RATIONALE, AIMS AND OBJECTIVES: Evidence-based medicine (EBM) has gained widespread acceptance in physical therapy. However, because little is known about the attitudes, knowledge and behaviour of physical therapists towards EBM, and their participation in research to generate EBM, we explored these aspects among physical therapy students, teachers, supervisors and practising physical therapists. METHODS: This is a cross-sectional survey in which participants completed a web-based questionnaire to determine their attitudes, knowledge and behaviour regarding EBM, and their participation in research. RESULTS: Questionnaires were sent to 814 participants of which 165 were returned. The overall mean score for attitude was 4.3 [standard deviation (SD) 1.0; range 1-7], which indicates a weak positive attitude. Teachers scored the highest (4.9, SD 1.2) and students the lowest (4.1, SD 0.8). Although most participants had some understanding of the technical terms used in EBM, only teachers felt able to explain these terms to others. Of the students, 45% rated their perceived EBM knowledge as bad and 45% as average, whereas 78% of the teachers considered that they had good knowledge. To answer clinical questions, most students generally use textbooks (96%) and the opinion of their supervisors (87.7%). CONCLUSIONS: There is a weak positive attitude of physical therapists, teachers, supervisors and students towards participating in research in general practice, but there is a lack of knowledge and active behaviour regarding EBM, especially among physical therapy students.

Lack of uniform diagnostic criteria for cervical radiculopathy in conservative intervention studies: a systematic review.

PURPOSE: Cervical radiculopathy (CR) is a common diagnosis. It is unclear if intervention studies use uniform definitions and criteria for patient selection. Our objective was to assess the uniformity of diagnostic criteria and definitions used in intervention studies to select patients with CR. METHODS: We electronically searched the Cochrane Controlled Trials Register, MEDLINE, EMBASE and CINAHL. Studies were included when evaluating conservative interventions in randomised clinical trials (RCTs) in patients with CR. Selection criteria and definitions for patients with CR were extracted and evaluated on their uniformity. RESULTS: Thirteen RCTs were included. Pain was used as an inclusion criterion in 11 studies. Inclusion based on the duration and location of pain varied between studies. Five studies used sensory symptoms in the arm as inclusion criterion. Four studies used cervical range of motion and motor disturbances as inclusion criteria, while reflex changes were used in two studies. Three studies included patients with a positive Spurling's test and two studies used it within a cluster of provocation tests. CONCLUSIONS: Criteria used to select patients with CR vary widely between different intervention studies. Selection criteria and test methods used are poorly described. There is consensus on the presence of pain, but not on the exact location of pain.

Education by general practitioners or education and exercises by physiotherapists for patients with whiplash-associated disorders? A randomized clinical trial.

STUDY DESIGN: Randomized clinical trial. OBJECTIVE: To compare the effectiveness of education and advice given by general practitioners (GPs) with education, advice, and active exercise therapy given by physiotherapists (PTs) for patients with whiplash-associated disorders. SUMMARY OF BACKGROUND DATA: Available evidence from systematic reviews has indicated beneficial effects for active interventions in patients with whiplash-associated disorders. However, it remained unclear which kind of active treatment was most effective. METHODS: Whiplash patients with symptoms or disabilities at 2 weeks after accident were recruited in primary care. Eligible patients still having symptoms or disabilities at 4 weeks were randomly allocated to GP care or physiotherapy. GPs and PTs treated patients according to a dynamic multimodal treatment protocol primarily aimed to increase activities and influence unfavorable psychosocial factors for recovery. We trained all health care providers about the characteristics of the whiplash problem, available evidence regarding prognosis and treatment, and protocol of the interventions. The content of the information provided to patients during treatment depended on the treatment goals set by the GPs or PTs. Also, the type of exercises chosen by the PTs depended on the treatment goals, and it was not explicitly necessary that exercise therapy was provided in all patients. Primary outcome measures included neck pain intensity, headache intensity, and work activities. Furthermore, an independent blinded assessor measured functional recovery, cervical range of motion, disability, housekeeping and social activities, fear of movement, coping, and general health status. We assessed outcomes at 8, 12, 26, and 52 weeks after the accident. RESULTS: A total of 80 patients were randomized to either GP care (n = 42) or physiotherapy (n = 38). At 12 and 52 weeks, no significant differences were found concerning the primary outcome measures. At 12 weeks, physiotherapy was significantly more effective than GP care for improving 1 of the measures of cervical range of motion (adjusted mean difference 12.3 degrees ; 95% confidence interval [CI] 2.7-21.9). Long-term differences between the groups favored GP care but were statistically significant only for some secondary outcome measures, including functional recovery (adjusted relative risk 2.3; 95% CI 1.0-5.0), coping (adjusted mean difference 1.7 points; 95% CI 0.2-3.3), and physical functioning (adjusted mean difference 8.9 points; 95% CI 0.6-17.2). CONCLUSIONS: We found no significant differences for the primary outcome measures. Treatment by GPs and PTs were of similar effectiveness. The long-term effects of GP care seem to be better compared to physiotherapy for functional recovery, coping, and physical functioning. Physiotherapy seems to be more effective than GP care on cervical range of motion at short-term follow-up.

Prognostic factors for poor recovery in acute whiplash patients.

The objective of our prospective inception cohort study was to identify prognostic factors for poor recovery in patients with whiplash-associated disorders grade 1 or 2 who still had neck pain and accompanying complaints 2 weeks after the accident. The study was carried out in a primary health care setting in The Netherlands and included 125 patients. The primary outcome measure was functional recovery defined in terms of neck pain intensity or work disability without medication use. The secondary outcome measures included neck pain intensity, work disability and sick leave. The outcomes were assessed at 4, 12 and 52 weeks after the accident. Prognostic factors were identified by logistic regression analyses. One year after the injury, 64% of the patients were recovered. Factors related to poor recovery were female gender, a low level of education, high initial neck pain, more severe disability, higher levels of somatisation and sleep difficulties. Neck pain intensity and work disability proved to be the most consistent predictors for poor recovery. The accuracy of the predictions of the prognostic models was high, meaning that the models adequately distinguished patients with poor recovery from those regarded as recovered. These findings add to the growing body of evidence, indicating that socio-demographic, physical and psychological factors affect short- and long-term outcome after whiplash injury. Our findings also indicate that care providers can easily identify patients at risk for poor recovery with a visual analogue scale for initial pain intensity and work-related activities.
