Combined Treatment of Face-to-Face Physical Therapy and Telerehabilitation in Workers with Whiplash Syndrome.

Objective: Interventions through telerehabilitation have shown positive effects in various clinical conditions, facilitating the return to work of the working population. This study aimed to compare conventional, center-based physiotherapy versus an intervention combining home- and center-based treatment for whiplash syndrome in workers enrolled in a mutual insurance company, evaluating differences in the number of face-to-face sessions and the duration of sickness absence. The secondary aim was to assess the acceptability and usability of the telerehabilitation intervention. Methods: The study population (n = 387) comprised workers aged 16 to 65 years who required physiotherapy due to whiplash (ICD-9 847.0). The main outcome variable was the number of face-to-face sessions. The duration of sickness absence was also calculated. A survey was also conducted to determine patient acceptance and usability of the platform. The analyses were adjusted for sex, age, occupation, and the center where the physiotherapy treatment was administered. Results: The number of face-to-face physiotherapy sessions dropped significantly, from 9 to 7, due to the implementation of telerehabilitation. This decrease was not associated with a longer duration of sickness absence. The difference in the median duration of sickness absence between patients who had not undergone telerehabilitation and those who had undergone telerehabilitation was -1 [95% CI= (-6 to 2)]. Conclusion: Telerehabilitation reduces the number of face-to-face physiotherapy sessions needed, which can reduce the care burden in physiotherapy centers and avoid the need for patients to travel (with a corresponding reduction in transportation costs), without increasing the duration of sickness absence.

Social determinants of health in adults with whiplash associated disorders.

OBJECTIVES: Although it is well-known that chronic diseases need to be managed within the complex biopsychosocial framework, little is known about the role of sociodemographic features in adults with whiplash-associated disorders (WAD) and their association with health outcomes. The aim of this study was to investigate the association between various sociodemographic features (age, sex, ethnicity, education, working, marriage, caring for dependents, and use of alcohol and drugs) and health outcomes (pain, disability, and physical/mental health-related quality of life) in WAD, both through their individual relationships and also via cluster analysis. METHODS: Independent t-tests and Kruskal-Wallis tests (with Mann-Whitney tests where appropriate) were used to compare data for each health outcome. Variables demonstrating a significant relationship with health outcomes were then entered into two-step cluster analysis. RESULTS: N = 281 participated in study (184 females, mean (±SD) age 40.9 (±10.7) years). Individually, level of education (p = 0.044), consumption of non-prescribed controlled or illegal drugs (p = 0.015), and use of alcohol (p = 0.008) influenced level of disability. Age (p = 0.014), marriage status (p = 0.008), and caring for dependents (p = 0.036) influenced mental health quality of life. Collectively, two primary clusters emerged, with one cluster defined by marriage, care of dependents, working status, and age >40 years associated with improved mental health outcomes (F 1,265 = 10.1, p = 0.002). DISCUSSION: Consistent with the biopsychosocial framework of health, this study demonstrated that various sociodemographic features are associated with health outcomes in WAD, both individually and collectively. Recognizing factors that are associated with poor health outcomes may facilitate positive outcomes and allow resource utilization to be tailored appropriately.

Novel Internet Support for Neck-Specific Rehabilitation Improves Work-Related Outcomes to the Same Extent as Extensive Visits to a Physiotherapy Clinic in Individuals with Chronic Whiplash-Associated Disorders: A Prospective Randomised Study.

PURPOSE: To address the current lack of information about work-related factors for individuals with whiplash-associated disorders (WAD) we investigated the effectiveness of 3 months of neck-specific rehabilitation with internet support in combination with four physiotherapy visits (NSEIT) compared to the same exercises performed twice a week (24 times) at a physiotherapy clinic (NSE). METHODS: This is a prospective, multicentre, randomised controlled trial regarding secondary outcomes of work-related factors in 140 individuals with chronic moderate/severe WAD with 3- and 15-month follow-up. RESULTS: There were no group differences between NSE and NSEIT in the Work Ability Scale or work subscales of the Neck Disability Index, Whiplash Disability Questionnaire or Fear Avoidance Beliefs Questionnaire (FABQ-work). Both groups improved in all work-related outcome measures, except for FABQ-work after the 3-month intervention and results were maintained at the 15-month follow-up. CONCLUSIONS: Despite fewer physiotherapy visits for the NSEIT group, there were no group differences between NSEIT and NSE, with improvements in most work-related measures maintained at the 15-month follow-up. The results of the present study are promising for those with remaining work ability problems after a whiplash injury.

Whiplash trauma did not predict jaw pain after 2 years: an explorative study.

OBJECTIVES: To explore predictive factors for the development and maintenance of jaw pain over a 2-year period. METHODS: One hundred nineteen cases (73 women) and 104 controls (59 women), mean age 34.9 years (SD 13.9), attended baseline and 2-year follow-up examinations. The whiplash cases visited the emergency department at Umeå University Hospital, Sweden, with neck pain within 72 h following a car accident, and baseline questionnaires were answered within a month after trauma. Controls were recruited via advertising. Inclusion criteria were age 18-70 years, living in Umeå municipality and Swedish speaking. The exclusion criterion was neck fracture for cases and a previous neck trauma for controls. Validated questionnaires recommended in the standardized Research Diagnostic Criteria for temporomandibular disorders were used. Jaw pain was assessed by two validated screening questions answered with "yes" or "no." A logistic regression analysis was used to predict the outcome variable jaw pain (yes/no) after 2 years. RESULTS: Whiplash trauma did not increase the odds of development of jaw pain over a 2-year period (OR 1.97, 95% CI 0.53-7.38). However, non-specific physical symptoms (OR 8.56, 95% CI 1.08-67.67) and female gender (OR 4.89, 95% CI 1.09-22.02) did increase the odds for jaw pain after 2 years. CONCLUSION: The development and maintenance of jaw pain after whiplash trauma are primarily not related to the trauma itself, but more associated with physical symptoms. CLINICAL RELEVANCE: The development of jaw pain in connection with a whiplash trauma needs to be seen in a biopsychosocial perspective, and early assessment is recommended.

Efficacy of acupuncture for whiplash injury: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to establish clinical evidence for acupuncture by analysing data from trials that demonstrated the efficacy of acupuncture for whiplash-associated disorder (WAD) with the following research question: Is acupuncture treatment effective for symptom alleviation in patients with WAD compared with other usual care? DESIGN: A systematic review and meta-analysis. DATA SOURCES: PubMed, Ovid Medline, Embase, The Cochrane Library, China National Knowledge Infrastructure, ScienceOn, KMBASE, Korean Studies Information Service System, Korea Med, Oriental Medicine Advanced Searching Integrated System and Research Information Sharing Service were searched from their inception to 1 October 2023. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCTs) using acupuncture on patients with WAD. The outcomes were the pain visual analogue scale (VAS) score or numerical rating scale score for neck pain, the range of motion (ROM) of the neck, the Neck Disability Index and safety. DATA EXTRACTION AND SYNTHESIS: Two independent researchers analysed and extracted data from the selected literatures. The risk of bias and the quality of evidence were assessed according to the Cochrane Handbook for Systematic Reviews of Interventions and the Grading of Recommendations Assessment, Development, and Evaluation method, respectively. RESULTS: A total of 525 patients with WAD from eight RCTs were included in this study. The meta-analysis revealed that the outcomes showed significant differences in the pain VAS score (standard mean difference (SMD): -0.57 (-0.86 to -0.28), p<0.001) and ROM-extension (SMD: 0.47 (0.05 to 0.89), p=0.03). The risk of bias assessment revealed that four studies published after 2012 (50%, 4 out of 8 studies) showed low bias in most domains. The pain VAS score was graded as having moderate certainty. CONCLUSION: Acupuncture may have clinical value in pain reduction and increasing the ROM for patients with WAD. High-quality RCTs must be conducted to confirm the efficacy of acupuncture in patients with WAD. TRIAL REGISTRATION NUMBER: PROSPERO CRD42021261595.

Demonstration of transverse ligament on 3D SPACE MRI in whiplash-associated disorder and nontraumatic conditions.

PURPOSE: This study aims to delineate the three-dimensional (3D) SPACE MRI findings of the transverse ligament (TL) in whiplash-associated disorder (WAD) patients, and to compare them with those from a nontraumatic group. METHODS: A retrospective analysis was performed on cervical spine MRI scans obtained from 46 patients with WAD and 62 nontraumatic individuals. Clinical features, including the WAD grade and stage, were recorded. The TL's morphological grade and the symmetricity of the lateral atlantodental interval was assessed using axial 3D T2-SPACE images. The morphological grading was evaluated using a four-point scale: 0 = homogeneously low signal intensity with normal thickness, 1 = high signal intensity with normal thickness, 2 = reduced thickness, 3 = full-thickness rupture or indistinguishable from surrounding structures. Additionally, the number of cervical levels exhibiting degeneration was documented. RESULTS: When comparing the WAD and nontraumatic groups, a significant difference was observed in the proportion of high-grade TL changes (grade 2 or 3) and the number of degenerated cervical levels. Logistic regression analysis revealed that high-grade TL changes and a lower number of degenerative levels independently predicted the presence of WAD. Within the WAD group, the subset of patients with high-grade TL changes demonstrated a significantly higher mean age than the low-grade group (grade 0 or 1). CONCLUSION: High-grade morphological changes in the TL can be detected in patients with WAD through the use of 3D SPACE sequences. Clinical relevance statement 3D SPACE MRI could serve as an instrumental tool in the assessment of TL among patients with WAD. Integrating MRI findings with patient history and symptomology could facilitate the identification of potential ligament damage, and may help treatment and follow-up planning.

Effectiveness of psychological interventions delivered by physiotherapists in the management of neck pain: a systematic review with meta-analysis.

Physiotherapists are increasingly using psychological treatments for musculoskeletal conditions. We assessed the effects of physiotherapist-delivered psychological interventions on pain, disability, and quality of life in neck pain. We evaluated quality of intervention reporting. We searched databases for randomized controlled trials (RCTs) comprising individuals with acute or chronic whiplash-associated disorder (WAD) or nontraumatic neck pain (NTNP), comparing physiotherapist-delivered psychological interventions to standard care or no treatment. Data were extracted regarding study characteristics and outcomes. Standardised mean difference (SMD) was calculated by random-effects meta-analysis. We evaluated certainty of evidence using Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) and intervention reporting using TIDieR. Fourteen RCTs (18 articles-4 detail additional outcome/follow-up data) were included comprising 2028 patients, examining acute WAD (n = 4), subacute/mixed NTNP (n = 3), chronic WAD (n = 2), and chronic NTNP (n = 5). Treatment effects on pain favoured psychological interventions in chronic NTNP at short-term (SMD -0.40 [95% CI -0.73, -0.07]), medium-term (SMD -0.29 [95% CI -0.57, 0.00]), and long-term (SMD -0.32 [95% CI -0.60, -0.05]) follow-up. For disability, effects favoured psychological interventions in acute WAD at short-term follow-up (SMD -0.39 [95% CI -0.72, -0.07]) and chronic NTNP at short-term (SMD -0.53 [95% CI -0.91, -0.15]), medium-term (SMD -0.49 [95% CI -0.77, -0.21]), and long-term (SMD -0.60 [95% CI -0.94, -0.26]) follow-up. GRADE ratings were typically moderate, and intervention reporting often lacked provision of trial materials and procedural descriptions. Psychological interventions delivered by physiotherapists were more effective than standard physiotherapy for chronic NTNP (small-to-medium effects) and, in the short term, acute WAD.

Evaluation of surface electromyography of selected neck muscles during the whiplash mechanism in aware and unaware conditions due to safe punching in kickboxing.

BACKGROUND: Kickboxing is considered as a combat sport in progress, in which injuries are frequent and significant, and close injury monitoring is highly recommended. Sports injuries to the head and neck are estimated to cause 70% deaths and 20% permanent disabilities although they are much less common than those to the limbs. Whiplash mechanism involves the rapid extension (opening) and flexion (bending) of neck. The purpose of the current study was to investigate the electromyographic activity of selected muscles in the whiplash mechanism in aware and unaware conditions of the safe punching in kickboxing so that we can design special exercises. METHOD: In the present study, 24 male kickboxing athletes aged 18-40 years were selected based on a purposive sampling method. The surface electromyography (EMG) signals of muscles were recorded with and without awareness of safe punching by using a nine-channel wireless EMG device. Additionally, a nine-channel 3D inertial measurement unit (IMU, wireless,) was utilized to determine the acceleration, kinematics, and angular velocity of the subjects' head. The statistical dependent t-test was applied to compare the EMG activity of each muscle, as well as its participation ratio. RESULTS: The results of statistical analysis represented a significant increase in the EMG activity of sternocleidomastoid (p = 0.001), upper trapezius (p = 0.001) and cervical erector spinae muscles (p = 0.001), as well as the neck extension and flexion angles between the athletes aware (open eyes) and unaware (closed eyes) of the safe punching. CONCLUSION: In this study, the EMG activity of the sternocleidomastoid, upper trapezius, and cervical erector spine muscles in the aware condition was significantly different from the activity under unaware condition. In fact, the intended muscles exhibited significantly different behaviors in preventing extension and flexion in the two conditions.

Physiotherapists' experiences of internet-based neck-specific exercises for patients with chronic whiplash-associated disorders.

Objective: Neck-specific exercises for individuals with chronic whiplash-associated disorders (WAD) have shown promising results, but there is also a need for more efficient and flexible ways of rehabilitation, such as use of digital health tools. Understanding physiotherapists' experiences of an internet-based tool may help to improve digital tools within physiotherapy. The purpose of this study was to describe how physiotherapists' experience an internet-based neck-specific exercise program for patients with chronic WAD. Methods: This study has a qualitative design. Focus group discussions were held with physiotherapists who have been treating patients with chronic WAD, using an internet-based neck-specific exercises program in a randomized controlled multi-center trial in south and central Sweden. Three focus groups were held with three participants in each group. Phenomenography was applied as a research approach for data analysis. Results: One main category was identified as "internet-based program as a complement to regular rehabilitation," with five descriptive sub-categories: (a) support in patient work; (b) usefulness based on a patient's prerequisites and preferences; (c) physiotherapist and patient interaction; (d) increasing efficiency in rehabilitation; and (e) enabling patient participation, autonomy and self-management. Conclusions: From a physiotherapy perspective, an internet-based program could work as a method of complementary support to the standard rehabilitation treatment for patients with chronic WAD, as long as it is interactive and adjustable to the individual. The internet-based program could lead to increased autonomy and self-efficacy, and save resources and time for physiotherapists and patients. Further, more research is needed to strengthen these digital tools within the healthcare system.

Selective acceptance of acute whiplash guidelines: a qualitative analysis of perceptions of health professionals in Australia.

PURPOSE: To explore health professionals' acceptance of the guidelines for acute whiplash associated disorders (WAD), and to identify barriers and facilitators to adherence. MATERIALS AND METHODS: Qualitative descriptive study involving focus group discussions among health professionals who treat people with WAD in primary and secondary care settings in New South Wales and Queensland, Australia. Twenty-eight health professionals (physiotherapists = 19; chiropractors = 6; osteopaths = 3) participated in six semi-structured focus group discussions that were held in independent offices in Sydney and Brisbane, Australia between September and December 2015. Discussions were audio recorded and verbatim, de-identified transcripts produced. Thematic analysis was conducted using an inductive approach to identify commonly held beliefs. RESULTS: Acceptance of guideline recommendations appeared to be influenced by factors related to the guideline itself, practitioner and practice characteristics, and patient-related factors. Specifically, acceptance was hindered by conflicting belief systems, ambiguity in guideline recommendations, and patient characteristics and expectations. CONCLUSIONS: Practitioners demonstrated a positive attitude towards the use of the guidelines in general; however, in some cases, acceptance of key recommendations appeared selective. Future guideline revision and implementation might focus on explaining the underlying principles of the guidelines, providing more detailed recommendations, and involving strategies that challenge inconsistent beliefs and promote informed decision-making. IMPLICATIONS FOR REHABILITATIONSelective acceptance of guideline recommendations in favour of those not requiring practice change may present a challenge for the implementation of evidence-based practice in the management of whiplash.Participants demonstrated variable, sometimes polar attitudes to guideline key messages and recommendations.Guideline developers need to focus more strongly on changing practitioner beliefs and attitudes, as well as better explaining the underlying principles of the guidelines, and providing more detailed recommendations.

Five to ten-year prognosis of whiplash injury-related chronic neck pain: A brief report.

BACKGROUND: Whiplash injury-related neck pain frequently hinders daily life activities, resulting in poor quality of life. Recovery time is prolonged in many patients. Long-term outcomes of refractory whiplash injury-related neck pain remain poorly understood. OBJECTIVE: This study aimed to evaluate the long-term prognosis of chronic whiplash injury-related neck pain. METHODS: We evaluated the prognosis of 38 patients with whiplash injury-induced neck pain via phone interviews. We investigated the data on current presence and degree of neck pain, current pain medication, physical modality or injection procedures, and difficulty performing daily life activities or occupational duties. RESULTS: At least 5 years after the whiplash injury, 34 patients (89.5%) experienced whiplash injury-related neck pain. The average numeric rating scale (NRS) score on the initial visit to our spine center was 5.3 ± 1.7 and that at the follow-up interview was 4.3 ± 2.6. Twenty-six (68.4%) patients had pain scores ⩾ 3 on the NRS. Additionally, 26 (68.4%) patients were receiving at least one of the following pain-management treatments: oral pain medications, physical modality, and injection procedures. Twenty-eight (73.7%) patients encountered difficulty performing daily life activities and occupational duties. CONCLUSIONS: The long-term prognosis of patients with whiplash injury-related neck pain was found to be poor.

Evaluation of implementation and effectiveness of neck-specific exercise for persistent disability and pain after whiplash injury: study protocol for a randomized controlled study using a hybrid 2 design.

BACKGROUND: Persistent pain and disability in whiplash-associated disorders (WAD) grades II and III are common. In two randomized controlled trials (RCTs) of neck-specific exercises (NSE), we have seen promising results in chronic WAD, with a sustained clinically important reduction in pain and disability. NSE can also be delivered through internet support (NSEIT) and a few visits to a physiotherapist, saving time and cost for both patients and providers. NSE have been shown to have positive effects in other neck pain disorders and we will evaluate the diffusion of the exercises to other patients. The aims of the proposed study are to evaluate an implementation strategy for NSEIT and NSE in primary health care and to evaluate the effectiveness of NSEIT and NSE in clinical practice. METHODS: The proposed study is a prospective cluster-randomized mixed-design study with hybrid 2 trial design. Reg. physiotherapists working in twenty physiotherapy clinics will be included. The primary implementation outcome is proportion of patients with neck pain receiving neck-specific exercise. Secondary outcomes are; physiotherapists attitudes to implementation of evidence-based practice, their self-efficacy and confidence in performing NSEIT/NSE, number of patients visits, and use of additional or other exercises or treatment. To further evaluate the implementation strategy, two qualitative studies will be performed with a sample of the physiotherapists. The primary outcome in the patient effectiveness evaluation is self-reported neck disability according to the Neck Disability Index (NDI). Secondary outcomes are pain intensity in the neck, arm, and head; dizziness; work- and health-related issues; and patient's improvement or deterioration over time. All measurements will be conducted at baseline and at 3 and 12 months. Physiotherapists´ self-efficacy and confidence in diagnosing and treating patients with neck pain will also be evaluated directly after their instruction in NSEIT/NSE. DISCUSSION: This trial will evaluate the implementation strategy in terms of adoption of and adherence to NSEIT and NSE in clinical primary health care, and measure diffusion of the method to other patients. In parallel, the effectiveness of the method will be evaluated. The results may guide physiotherapists and health care providers to sustainable and effective implementation of effective exercise programs. TRIAL REGISTRATION: The randomized trial is registered on ClinicalTrials.gov , NCT05198258 , initial release date January 20, 2022.

Associations Between Resting Heart Rate, Resting Blood Pressure, Psychological Variables and Pain Processing in Chronic Whiplash-Associated Disorder: A Cross-Sectional Study.

OBJECTIVE: Autonomic nervous system dysfunction has been implicated in chronic whiplash-associated disorder (WAD). However, the relationship between autonomic variables (e.g., resting heart rate and blood pressure) and clinical factors in chronic WAD is not well understood. This study sought to examine the associations between resting heart rate, resting blood pressure, pain processing and psychological variables in chronic WAD and in pain-free controls. DESIGN: Secondary analysis of a cross-sectional study. SETTING: University clinical research laboratory. SUBJECTS: Thirty-six people with chronic WAD Grade II (mean [SD] age 40.1 [14.6] years, 28 females) and 25 pain-free controls (35.6 [13.0] years, 17 females). METHODS: Participants had resting heart rate, systolic and diastolic blood pressure measured. Pain processing measures comprised: (i) pain pressure threshold at the cervical spine, hand and leg, (ii) temporal summation at the cervical spine and hand, and (iii) conditioned pain modulation. Psychological outcomes included measures of kinesiophobia, pain catastrophizing and post-traumatic stress symptoms. Correlations between autonomic variables, pain processing and psychological variables were determined (P < .05, 5% FDR). RESULTS: No significant correlations between autonomic and pain processing variables, or autonomic and psychological variables were found in the chronic WAD group. In the control group, diastolic blood pressure was positively correlated with cervical spine pressure pain threshold (r = 0.53, P = .007). CONCLUSIONS: An association between blood pressure and pain sensitivity was observed in the control group but not the chronic WAD group. Such an association appears to be disrupted in chronic WAD, which may infer involvement of autonomic pathways in the pathophysiology of this condition.

Do expectations of recovery improve risk assessment for people with whiplash-associated disorders? Secondary analysis of a prospective cohort study.

BACKGROUND: WhipPredict, which includes prognostic factors of pain-related disability, age and hyperarousal symptoms, was developed and validated for prediction of outcome in people with whiplash associated disorders (WAD). Patient expectations of recovery was not an included factor, though is known to mediate outcomes. The aim of this study was to determine whether the addition of expectations of recovery could improve the accuracy of WhipPredict. METHODS: Two hundred twenty-eight participants with acute WAD completed questionnaires (WhipPredict and expectations of recovery) at baseline. Health outcomes (neck disability index (NDI) and Global Perceived Recovery (GPR)) were assessed at 6- and 12-months post injury. Cut-off points for expectations of recovery predictive of both full recovery (NDI ≤10 % , GPR ≥ 4) and poor outcome (NDI ≥30 % , GPR ≤ - 3) were determined, and multivariate logistic regression analyses were used to compare models with and without this variable. RESULTS: Expectations of recovery improved or maintained the accuracy of predictions of poor outcome (6-months: sensitivity 78 to 83%, specificity maintained at 79.5%; 12-months: sensitivity maintained at 80%, specificity 69 to 73%). The sensitivity of predictions of full recovery improved (6-months: 68 to 76%; 12-months: 57 to 81%), though specificity did not change appreciably at 6 months (80 to 81%) and declined at 12 (83 to 76%). ROC curves indicated a larger and more consistent improvement in model performance when expectations of recovery were added to the pathway predictive of full recovery. CONCLUSIONS: The addition of expectations of recovery may improve the accuracy of WhipPredict, though further validation is required.

Exercise therapy for whiplash-associated disorders: a systematic review and meta-analysis.

OBJECTIVES: Acute as well as chronic pain syndromes are common after whiplash trauma and exercise therapy is proposed as one possible intervention strategy. The aim of the present systematic review was to evaluate the effect of exercise therapy in patients with Whiplash-Associated Disorders for the improvement of neck pain and neck disability, compared with other therapeutic interventions, placebo interventions, no treatment, or waiting list. CONTENT: The review was registered in Prospero (CRD42017060356) and conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search in PubMed, Scopus and Cochrane from inception until January 13, 2020 was combined with a hand search to identify eligible randomized controlled studies. Abstract screening, full text assessment and risk of bias assessment (Cochrane RoB 2.0) were conducted by two independent reviewers. SUMMARY: The search identified 4,103 articles. After removal of duplicates, screening of 2,921 abstracts and full text assessment of 100 articles, 27 articles that reported data for 2,127 patients were included. The included articles evaluated the effect of exercise therapy on neck pain, neck disability or other outcome measures and indicated some positive effects from exercise, but many studies lacked control groups not receiving active treatment. Studies on exercise that could be included in the random-effect meta-analysis showed significant short-term effects on neck pain and medium-term effects on neck disability. OUTLOOK: Despite a large number of articles published in the area of exercise therapy and Whiplash-Associated Disorders, the current evidence base is weak. The results from the present review with meta-analysis suggests that exercise therapy may provide additional effect for improvement of neck pain and disability in patients with Whiplash-Associated Disorders.

Prevalence of whiplash injury and its association with quality of life in local residents in Japan: A cross sectional study.

BACKGROUND: Associations between whiplash injuries and quality of life (QOL) have been previously published by conducting surveys among patients. This study aimed to investigate the prevalence of whiplash injuries in a Japanese community, and the association between whiplash injuries and QOL was also determined. METHODS: In all, 1140 volunteers participated in this study, filled out a questionnaire about whether they had experienced a whiplash injury, or had any neck pain or neck-shoulder stiffness in the previous 3 months, and completed the Medical Outcomes Study 36-Item Short-Form Health Survey. QOL was evaluated from the eight domain scores, and the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. We compared the characteristics, habits, history, medication, body mass index, and health-related QOL (eight domains, PCS and MCS scores) between the groups with whiplash injuries and no whiplash injuries for each sex. Multiple linear regressions with the forced-entry procedure were performed to evaluate the effects of a whiplash injury on the PCS and MCS. A p-value of <0.05 was considered statistically significant. RESULTS: The prevalence of whiplash injuries was 7.7% and 9.6% in men and women, respectively. The percentage of those who experienced whiplash injuries with symptoms persisting for more than 3 months was 34.3% and 24.2% in men and women, respectively. The prevalence of neck symptoms was significantly higher in the whiplash injury group than in the non-whiplash injury group. Multiple linear regression analysis showed that, although whiplash injuries were associated with poor health-related QOL in men, age was more associated with health-related QOL than whiplash injuries in both sexes. CONCLUSION: The prevalence of whiplash injuries was 7.7% and 9.6% in men and women in local residents in Japan, respectively. Whiplash injuries were poorly associated with a poor health-related QOL in men (P = 0.015).

A case report of "minor" trauma leading to a major disability: whiplash-associated dysphagia, dysphonia, and dysgeusia.

"Whiplash"-type injuries are commonly encountered and often cause neck pain, neck stiffness, and headaches. However, these injuries can have rare and poorly recognized complications, such as the development of a prevertebral hematoma leading to acute respiratory failure in the emergency department, followed by severe, life-threatening dysphagia and recurrent aspirations. In the patient described herein, a whiplash injury was accompanied by vocal cord paralysis and dysphonia (vagus nerve), dysgeusia (glossopharyngeal nerve, vagus nerve), and upper esophageal spasm (cricopharyngeal muscle, vagus nerve). It is unlikely that this was a complication of cervical fusion surgery. Instead, a combined stretch-induced lower cranial nerve injury, possibly on the exit of these nerves through the jugular foramen, seems to be a likely, but underappreciated mechanism occurring in rare instances of whiplash injuries.

Use of Soft Cervical Collar among Whiplash Patients in Two Italian Emergency Departments Is Associated with Persistence of Symptoms: A Propensity Score Matching Analysis.

PURPOSE: Although the use of soft cervical collars in the emergency department (ED), for whiplash-associated disorders (WAD), is controversial, it is still widely adopted. The purpose of our study was to investigate the impact of the early use of soft cervical collars on the return to the ED, within three months of a road traffic collision. METHODS: We conducted a retrospective observational study on WAD patients from two EDs in Verona (Italy). Patients in the earlier acute phase of WAD (within 48 h from the trauma) were included; those with serious conditions (WAD IV) were excluded. As an end point, we considered patients who returned to the ED complaining of WAD symptoms within three months as positive outcome for WAD persistence. RESULTS: 2162 patients were included; of those, 85.4% (n = 1847/2162) received a soft cervical collar prescription. Further, 8.4% (n = 156/1847) of those with a soft cervical collar prescription, and 2.5% (n = 8/315) of those without a soft cervical collar (p < 0.001) returned to the ED within three months. The use of the soft cervical collar was an independent risk factor for ED return within three months, with an OR, adjusted for possible clinical confounders, equal to 3.418 (95% CI 1.653-7.069; p < 0.001). After the propensity score matching, 25.5% of the patients (n = 25/98) using the soft cervical collar returned to the ED at three months, compared to the 6.1% (n = 6/98) that did not adopt the soft cervical collar. The use of a soft cervical collar was associated with ED return with an OR = 4.314 (95% CI 2.066-11.668; p = 0.001). CONCLUSIONS: Our study shows that the positioning of the soft collar in a cohort of patients with acute WAD, following a rear-end car collision, is an independent potential risk factor to the return to the ED. Clinically, the use of the collar is a non-recommended practice and seems to be related to an increased risk of delayed recovery. There is a need to inform healthcare providers involved in the ED of the aim to limit the use of the soft cervical collar. A closer collaboration between clinicians (e.g., physicians, physical therapists, nurses) is suggested in the ED. Future primary studies should determine differences between having used or not having used the collar, and compare early physical therapy in the ED compared with the utilization of the collar.

Experiences of responsiveness to exercise in people with chronic whiplash: A qualitative study.

Exercise is recommended in clinical guidelines for the treatment of chronic whiplash associated disorders (WAD). However, randomised controlled trials have shown similar effects for comprehensive exercise programs and advice. To date, there is no clear understanding of why some individuals with WAD appear to respond to exercise whilst others do not. The aim of this study was to explore the experiences and self-reported characteristics of people with chronic whiplash identifying as 'responders' and 'non-responders' to exercise. Semi-structured interviews were conducted with 13 people with chronic whiplash (patients) and seven treating physiotherapists. Patients were asked whether they responded to the exercise program, and what contributed to this. Physiotherapists were asked to share their experiences about the characteristics of people that appear to respond to exercise, and those that do not. An interpretive descriptive approach was selected to facilitate the generation of discipline-specific knowledge. Four themes were generated from patient and physiotherapist interviews, including: (1) the therapeutic relationship, (2) exercise experiences and beliefs, (3) self-efficacy and acceptance, (4) physical and psychological determinants of responsiveness. Responsiveness to exercise is complex and multifaceted. Clinicians may seek to identify the presence of discrete physical impairment(s) (e.g., range of motion restriction), and where present, determine whether targeted exercise results in an immediate and positive response. Clinicians may also focus their efforts on developing aspects of the therapeutic relationship identified as important to patients, such as hope, partnership and rapport.
