A guide to cranial nerve testing for musculoskeletal clinicians

Neurological examination for cervical radiculopathy: a scoping review

BACKGROUND

To diagnose cervical radiculopathy according to the International Association for the Study of Pain definition, signs of neurological deficits must be examined with the neurological examination. However, the diagnostic accuracy of the standard neurological examination remains unclear, and no clear recommendations exist about standard components. Therefore, the objectives of this review are to map the research about the diagnostic accuracy, components, and performance of the neurological examination for cervical radiculopathy.

METHOD

PubMed, Embase, Scopus, Cinhal, DiTA databases were searched up to February 23rd, 2024. Additional studies were identified through screening reference lists of the included studies. Studies on neurological examination procedures and their diagnostic accuracy for cervical radiculopathy were included.

RESULTS

From an initial 12,365 records, 6 articles met the inclusion criteria. All articles were cross-sectional studies and compared the neurological examination with electrodiagnostic tests or magnetic resonance imaging. Reduced tendon reflexes were found to be most specific (81% (95% CI 69-89%) to 99% (95% CI not reported)), while somatosensation testing was least sensitive (25% (95% CI 12-38%; -LR 0.84) to 52% (95% CI 30-74%)). Taking all components into account resulted in higher specificity (98% (95% CI not reported) to 99% (95% CI 95-100%)) but lower sensitivity (7% (95% CI not reported) to 14% (95% CI 5-16%)) compared to electrodiagnostic tests.

CONCLUSIONS

We found varying operational definitions of radiculopathy, suboptimal reference standards, and great heterogeneity in the neurological examination procedure and its diagnostic accuracy. Future research should address these issues to establish the clinical utility of the neurological examination for cervical radiculopathy.

Understanding degenerative cervical myelopathy in musculoskeletal practice

BACKGROUND

Degenerative cervical myelopathy (DCM) is a clinical syndrome characterized by a progressive compression of the spinal cord. DCM often looks like common symptoms of aging or bilateral carpal tunnel syndrome in its early stages, requiring careful differential diagnosis. Identifying DCM is a real challenge as no validated screening tools are available for making the DCM diagnosis. Potentially, individuals with DCM may experience misdiagnosis or substantial diagnostic delays, with an enhanced risk of irreversible neurological consequences if not promptly addressed. Despite the increasing prevalence, there is a lack of awareness about DCM among both the public and healthcare professionals. However, patients may seek physiotherapy to obtain a diagnosis or access treatment.

METHODS

A comprehensive (non-systematic) review of the literature about DCM epidemiology, pathophysiology, clinical presentation, diagnostic methods, and management was conducted.

RESULTS

A guide and essential knowledge to facilitate clinicians to understand DCM and to enhance clinical reasoning skills, performance and interpretation of the examination are provided. Interdisciplinary collaboration and optimal referral methods are also handled.

CONCLUSION

The aim of this article is to summarize and enhance physiotherapists' essential knowledge of the differential diagnosis and management of patients with DCM.

Recognition of a patient with neck autonomic dysfunction: findings from a rare case report of harlequin syndrome in direct access physiotherapy

BACKGROUND

Harlequin syndrome is a rare autonomic condition consisting of unilateral facial flushing and sweating induced by heat, emotion or physical activity. The affected side presents anhidrosis and midline facial pallor due to denervation of the sympathetic fibers.

CASE DESCRIPTION

This case describes a patient who reported right-side redness of the face associated with hyperhidrosis during physical activity. She had two previous major motor vehicle accidents. The patient demonstrated difficulties in the visual accommodation of the left eye, but cranial nerve assessment was unremarkable; the patient was then referred to an ophthalmologist, who excluded any autonomic dysfunction as the primary cause of convergence and visual acuity.

OUTCOMES

A left-sided sympathetic dysfunction with Harlequin sign diagnosis was made followed by a progressive compensatory adaptation of the right face. The patient was educated and reassured about the benign nature of her problem.

DISCUSSION

Knowledge of the autonomic nervous system is still limited in clinical practice. Although challenging, physiotherapists should develop the knowledge and ability needed to perform appropriate assessment of autonomic dysfunctions.

CONCLUSION

A dispositional reasoning model should be considered in differential diagnosis.

Sleep disorders and orofacial pain: insights for dental practice

In dental sleep medicine several sleep disorders commonly coexist with pain, contributing to complex clinical presentations which might affect the provision of appropriate and timely treatment. There are associations between sleep disorders and pain in general, as well as with specific orofacial pain conditions. As many as five of six patients with orofacial pain can present with sleep problems. The comorbidity of orofacial pain and sleep disorders overlays a complex web of altered neurobiological mechanisms that predispose to the chronification of orofacial pain. This review discusses the relationship between orofacial pain and sleep disorders and highlights their interactions and the neurobiological mechanisms underlying those relationships.

Lymphoma masquerading as jaw pain, headache, and syncope: A case report

BACKGROUND

Lymphomas of parapharyngeal space often have complex manifestations, posing a diagnostic dilemma for clinicians.

CASE DESCRIPTION

A 64-year-old man sought treatment for a 4-month history of unresolving right-sided headache and jaw pain associated with syncope, all of which started with a toothache. Since the onset of pain, the patient had undergone multiple diagnostic tests with various specialists, with no pain relief. A detailed clinical and radiologic examination by an orofacial pain specialist revealed diffuse large B-cell lymphoma in the parapharynx.

PRACTICAL IMPLICATIONS

A thorough knowledge of the head and neck anatomy helps in identifying the pathophysiology of complex orofacial pain manifestations, which assists in early diagnosis and treatment.

Physiotherapy Screening for Referral of a Patient with Peripheral Arterial Disease Masquerading as Sciatica: A Case Report

Many causes potentially underline pain in the lower extremities, presenting a real challenge for primary care clinicians in the recognition of the source of the patient's complaints. Peripheral arterial disease (PAD) is defined as a total or partial blockage of the vessels that supply blood from the heart to the periphery. PAD of the lower extremities may masquerade as lumbosacral radiculopathy (LSR)-a common source of leg pain. Physiotherapists should be able to screen for PAD in people presenting with pain in the lower extremities. Failure to correctly screen for PAD could put the patient at risk of severe disability and possible permanent sequelae. This case report outlines the relevant concepts relating to the pathophysiology, screening, and differential diagnosis of PAD, and then further describes the relevant findings from the history and physical examination from the physiotherapist's perspective in a patient with an unusual symptom presentation. Although the patient was referred by a physician with a diagnosis of LSR, our case highlights the pivotal role of skilled physiotherapists in triaging a severe lower-limb PAD in need of referral. Therefore, this case report aims to increase clinicians' awareness of the clinical features of a complex case of PAD.

Recognition of Prodromal Hypoglossal Nerve Palsy Presenting with Neck Pain as Primary Complaint: Findings from a Rare Case Report in Direct Access Physiotherapy during the COVID-19 Pandemic

Neck pain (NP) is the second most common musculoskeletal disorder. Spinal cysts (SCs) are cystic dilatations of the synovial sheaths in joints and tendons. SCs are extremely rare in the cervical spine. Typically, patients are unaware of having an SC due to its asymptomatic nature; however, when cervical SC extends, its volume could compress the surrounding structures, such as the hypoglossal nerve. Isolated hypoglossal nerve palsy (HNP) is very rare and typically presents with unilateral atrophy of the musculature of the tongue and contralateral tongue deviation. Often, patients with HNP also report occipital/neck pain. A 75-year-old man with occipital/neck pain as a primary complaint. Although difficult to observe because of the filtering facepiece two mask, difficulties in articulation and sialorrhea during the interview were noticed. These latter were cues to consider CN examination that revealed CN XII palsy. This prompted a referral for further examination that revealed an SC compressing the right hypoglossal canal. The patient was not considered a surgical candidate and was managed conservatively. This case report outlines the relevant findings relating to the triage of a rare isolated hypoglossal nerve palsy from the physiotherapist's perspective within a complex setting because of the COVID-19 pandemic. Although referred with a diagnosis of cervical radiculopathy, our case highlights that skilled physiotherapists may play a fundamental role in both the recognition and, when applicable, subsequent novel management of a non-musculoskeletal presentation.

Physiotherapy Screening for Referral of a Patient with Patent Foramen Ovale Presenting with Neck Pain as Primary Complaint: A Case Report

Neck pain is a common musculoskeletal disorder encountered by physiotherapists. However, it may be the early manifestation of more alarming conditions, such as cardiovascular diseases mimicking musculoskeletal pain. Patent foramen ovale (PFO) is a congenital heart defect consisting of a small opening between the right and the left atrium. A 56-year-old male presented with neck pain and head heaviness as primary complaints. The cardiovascular profile and the behavioral symptoms led the physiotherapist to find an exaggerated blood pressure response during exercise; in addition to subtle neurological signs, this prompted the physiotherapist to make an urgent referral. At the emergency department a PFO was diagnosed. To the best of the authors' knowledge, this is the first case to describe a rare clinical presentation of a PFO presenting neck pain as primary complaint. This case report emphasizes the importance for physiotherapists to be able to triage patients for conditions outside their scope suggestive of further medical investigation.

Headache, Loss of Smell, and Visual Disturbances: Symptoms of SARS-CoV-2 Infection? A Case Report

OBJECTIVE

The purpose of this case report is to describe the main components of the history and physical examination that led to idiopathic intracranial hypertension differential diagnosis, which initially was investigated as COVID-19.

METHODS (CASE DESCRIPTION)

A 28-year-old woman complaining of constant headache and loss of smell and taste was suspected as SARS-CoV-2 infection by her general practitioner. She underwent 3 molecular swab tests, all negative, then decided to seek her physical therapist for relieving headache.

RESULTS

The full cranial nerve examination revealed impaired olfactory (CNI), abducens (CN VI), and facial (CN VII) nerves, leading the physical therapist to refer the patient to a neurosurgeon for a suspected central nervous system involvement. The neurosurgeon prescribed a detailed MRI and an ophthalmologic examination, which allowed for the final diagnosis of idiopathic intracranial hypertension.

CONCLUSION

An urgent lumbo-peritoneal shunting surgery resolved the patient's symptoms and saved her sight. Despite the ongoing COVID-19 pandemic, health care professionals must pay attention to properly investigating patients' signs and symptoms using comprehensive clinical reasoning, considering the screening for referral to specialist medical attention.

IMPACT

A thorough physical examination is required for every patient even if patients' signs and symptoms are in line with apparent common and widespread pathologies. Cranial nerve evaluation is an essential component of the physical therapist assessment and decision-making process. The ongoing pandemic highlighted the fundamental assistance of physical therapists toward physicians in the screening and management of musculoskeletal diseases.

A guide to identify cervical autonomic dysfunctions (and associated conditions) in patients with musculoskeletal disorders in physical therapy practice

BACKGROUND

Differential diagnosis is a hot topic in physical therapy, especially for those working in a direct access setting dealing with neck pain and its associated disorders. All international guidelines agree in recommending to first rule out non-musculoskeletal pathologies as the cause of signs and symptoms in the patient. Although the autonomic nervous system (ANS) has a crucial role and is also involved in pain conditions, coverage of it in neuroscience textbooks and educational programmes is limited and most healthcare professionals are unfamiliar with it. Although autonomic conditions are benign in nature, they are clinically of great importance as they may be a 'red flag' warning of an injury along the sympathetic pathway. Therefore, sound knowledge of the ANS system is essential for clinicians.

OBJECTIVE

To develop physical therapists' knowledge of and confidence in understanding cervical ANS function and dysfunction, thus enhancing clinical reasoning skills and the pattern recognition process, and performing and interpreting objective examinations.

METHODS

This master class provides an introductory guide and essential knowledge to facilitate clinicians to understand cervical autonomic dysfunctions and their clinical evaluation. The optimal referral method is also handled.

CONCLUSIONS

Gaining knowledge and understanding of the ANS, its function, its dysfunction, and the related clinical manifestations is likely to lead to a decision-making process driven by 'science and conscience'. This will empower physical therapists to be aware of subtle clues that may be offered by patients during the interview and history intake leading to the appropriate physical examination and triage.

Pre-manipulative cervical spine testing and sustained rotation do not influence intracranial hemodynamics: an observational study with transcranial Doppler ultrasound

INTRODUCTION

Manual joint mobilization and manipulation are recommended therapeutic interventions for people with neck pain. High-velocity thrust and sustained techniques have an uncertain association with serious arterial trauma. The validity of pre-manipulative tests of the cervical spine is often questioned, and the understanding of the effect of head/neck position on blood flow is still incomplete. Most of the evidence concerning hemodynamics in this area relates to extracranial flow (vertebral and carotid artery). Less is understood about the effects on intracranial flow while performing pre-manipulative tests and sustained positions like end of range cervical rotation mobilization. The aim of the study was to assess the influence of commonly used evaluation and treatment positions on intracranial hemodynamic parameters.

METHOD

A randomized, cross-over observational study using ultrasonography on healthy subjects (n = 19) was conducted to measure hemodynamic parameters (peak systolic velocity and end diastolic maximum) of intracranial arterial systems. Two test positions (sustained pre-manipulative thrust C0-1 and sustained cervical end of range rotation) were compared with a sham position for each test position.

RESULTS

:Neither the sequence of tests performed nor an independent variable (the two positions) had a significant effect (p < 0.05) on peak systolic velocity (PSV) or end diastolic maximum (EDM).

DISCUSSION

No effects from commonly used assessment and treatment of neck positions on hemodynamic parameters were found. This is consistent with previous studies. Further study is indicated on people with symptoms and known pathologies.

Speech and Nonspeech Parameters in the Clinical Assessment of Dysarthria: A Dimensional Analysis

Nonspeech (or paraspeech) parameters are widely used in clinical assessment of speech impairment in persons with dysarthria (PWD). Virtually every standard clinical instrument used in dysarthria diagnostics includes nonspeech parameters, often in considerable numbers. While theoretical considerations have challenged the validity of these measures as markers of speech impairment, only a few studies have directly examined their relationship to speech parameters on a broader scale. This study was designed to investigate how nonspeech parameters commonly used in clinical dysarthria assessment relate to speech characteristics of dysarthria in individuals with movement disorders. Maximum syllable repetition rates, accuracies, and rates of isolated and repetitive nonspeech oral-facial movements and maximum phonation times were compared with auditory-perceptual and acoustic speech parameters. Overall, 23 diagnostic parameters were assessed in a sample of 130 patients with movement disorders of six etiologies. Each variable was standardized for its distribution and for age and sex effects in 130 neurotypical speakers. Exploratory Graph Analysis (EGA) and Confirmatory Factor Analysis (CFA) were used to examine the factor structure underlying the diagnostic parameters. In the first analysis, we tested the hypothesis that nonspeech parameters combine with speech parameters within diagnostic dimensions representing domain-general motor control principles. In a second analysis, we tested the more specific hypotheses that diagnostic parameters split along effector (lip vs. tongue) or functional (speed vs. accuracy) rather than task boundaries. Our findings contradict the view that nonspeech parameters currently used in dysarthria diagnostics are congruent with diagnostic measures of speech characteristics in PWD.

International Framework for Examination of the Cervical Region for Potential of Vascular Pathologies of the Neck Prior to Musculoskeletal Intervention: International IFOMPT Cervical Framework

SYNOPSIS: This position statement, stemming from the International IFOMPT (International Federation of Orthopaedic Manipulative Physical Therapists) Cervical Framework, was developed based upon the best contemporary evidence and expert opinion to assist clinicians during their clinical reasoning process when considering presentations involving the head and neck. Developed through rigorous consensus methods, the International IFOMPT Cervical Framework guides assessment of the cervical spine region for potential vascular pathologies of the neck in advance of planned interventions. Within the cervical spine, events and presentations of vascular pathologies of the neck are rare but are an important consideration as part of patient examination. Vascular pathologies may be recognizable if the appropriate questions are asked during the patient history-taking process, if interpretation of elicited data enables recognition of this potential, and if the physical examination can be adapted to explore any potential vasculogenic hypothesis.

Intracranial Epidermoid Cyst Mimics Musculoskeletal Shoulder Disease: Findings from a Case Report in Physiotherapy Clinical Practice

Shoulder pain is often attributable to a musculoskeletal disorder, but in some instances, it may be linked to pathologies outside the physiotherapist's area of expertise. Specifically, some intracranial problems can cause pain and disability to the shoulder complex. This case report aims to describe the clinical presentation, history taking, physical examination, and clinical decision-making procedures in a patient with an intracranial epidermoid cyst mimicking a musculoskeletal disorder of the shoulder girdle. A 42-year-old man complained of pain and disability in his left shoulder. Sudden, sharp pain was reported during overhead movements, associated with intermittent tingling of the left upper trapezius and left scapular area. Moreover, the patient reported reduced hearing in his left ear and left facial dysesthesia. The physical examination led the physiotherapist to hypothesize a pathology outside the physiotherapist's scope of practice and to refer the patient to another health professional to further investigate the patient through imaging. It is essential for the physiotherapist to recognize when the patient's clinical condition requires a referral to another healthcare professional. Therefore, the physiotherapist must be able to, in a timely manner, identify signs and symptoms suggesting the presence of medical pathology beyond his expertise, through appropriate medical history collection and physical evaluation.

Knowledge, beliefs, and attitudes of spinal manipulation: a cross-sectional survey of Italian physiotherapists

BACKGROUND AND OBJECTIVE

High-velocity low-amplitude thrust spinal manipulation (SM) is a recommended and commonly used manual therapy intervention in physiotherapy. Beliefs surrounding the safety and effectiveness of SM have challenged its use, and even advocated for its abandonment. Our study aimed to investigate the knowledge and beliefs surrounding SM by Italian physiotherapists compared with similar practitioners in other countries.

METHODS

An online survey with 41 questions was adapted from previous surveys and was distributed via a mailing list of the Italian Physiotherapists Association (March 22-26, 2020). The questionnaire was divided into 4 sections to capture information on participant demographics, utilization, potential barriers, and knowledge about SM. Questions were differentiated between spinal regions. Attitudes towards different spinal regions, attributes associated with beliefs, and the influence of previous educational background were each evaluated.

RESULTS

Of the 7398 registered physiotherapists, 575 (7.8%) completed the survey and were included for analysis. The majority of respondents perceived SM as safe and effective when applied to the thoracic (74.1%) and lumbar (72.2%) spines; whereas, a smaller proportion viewed SM to the upper cervical spine (56.8%) as safe and effective. Respondents reported they were less likely to provide and feel comfortable with upper cervical SM (respectively, 27.5% and 48.5%) compared to the thoracic (respectively, 52.2% and 74.8%) and lumbar spines (respectively, 46.3% and 74.3%). Most physiotherapists (70.4%) agreed they would perform additional screening prior to upper cervical SM compared to other spinal regions. Respondents who were aware of clinical prediction rules were more likely to report being comfortable with SM (OR 2.38-3.69) and to perceive it as safe (OR 1.75-3.12). Finally, physiotherapists without musculoskeletal specialization, especially those with a traditional manual therapy background, were more likely to perform additional screening prior to SM, use SM less frequently, report being less comfortable performing SM, and report upper cervical SM as less safe (p < 0.001).

DISCUSSION

The beliefs and attitudes of physiotherapists surrounding the use of SM are significantly different when comparing the upper cervical spine to other spinal regions. An educational background in traditional manual therapy significantly influences beliefs and attitudes. We propose an updated framework on evidence-based SM.

Physical Performance Tests in Adult Neck Pain Patients with and without Clinical Myelopathic Signs: A Matched Case-Control Study

Patients with neck pain may experience cervical myelopathy, this may be detected by clinical myelopathic signs, although they did not have any symptom of myelopathy, except having neck pain. Decreasing physical performance is one symptom of cervical myelopathy that can lead to reduced quality of life in the elderly, however, in adult neck pain with clinical myelopathic signs have not been evaluated. Therefore, this research aimed to compare physical performance in two groups of adult patients with neck pain: those with and without clinical myelopathic signs. A total of 52 participants, gender, age, and body mass index (BMI) matched were allocated into 2 groups of 26 subjects with neck pain, those with, and without, clinical myelopathic signs. The grip and release test, nine-hole peg test, ten second step test and foot-tapping test were evaluated. The group of neck pain participants with clinical myelopathic signs exhibited greater impairment in all the tests than the group without clinical myelopathic signs (p < 0.001). Effect sizes (Cohen’s d) were grip and release test: 2.031, nine-hole peg test: 1.143, ten second step test: 1.329, and foot-tapping test: 0.798. Neck pain participants with clinical myelopathic signs demonstrated reduced physical performance. Physical performance tests may need to assessed in adult patients with neck pain who had clinical myelopathic signs.

Assessing cardiovascular parameters and risk factors in physical therapy practice: findings from a cross-sectional national survey and implication for clinical practice

BACKGROUND

Cardiovascular diseases are the leading cause of death and comorbidity worldwide. High blood pressure and resting heart rate are risk factors (or vital signs) critical to cardiovascular health, patient safety, and medical management. Physiotherapists play a fundamental role in risk factor identification, early diagnosis, and subsequent management of cardiovascular disease. To date there is limited research in Europe investigating the level of knowledge and skills possessed by physiotherapists regarding cardiovascular disease screening. Three studies previously observed inadequate vital signs screening behaviors of physiotherapists practicing in the United States and Saudi Arabia. The primary aim of this study was to investigate cardiovascular knowledge and screening practices among Italian physiotherapists, according to the current practice recommendations.

METHODS

A Cross-Sectional Survey was developed adapting two previous surveys. The survey was administered to members of the Italian Physiotherapy Association. Chi squared test, Mann-Whitney test or Kruskal-Wallis test were used to study differences among subgroups and question responses.

RESULTS

The required sample size was met with total of 387 Italian physiotherapists completing the survey. 80% consider relevant cardiovascular assessment. However, 72.2% were not familiar to guidelines recommendations and only 50% screen vital signs routinely. Their knowledge of normative blood pressure (high-normal, 16%; hypertension, 12%) and heart rate values (bradycardia, 24%; tachycardia, 26%) were low. Although participants reported being skilled for blood pressure measurement (quite sure, 52%; sure, 27%), their adherence to guidelines is low (baseline measurement on both arm, 25%; 3 repeated measures, 46%). Only 27.8% reported to measure exercise related BP and 21.3% of them understood the concept of exaggerated BP. No significant differences between subgroups were found.

CONCLUSIONS

Our study revealed that a concerning proportion of Italian physiotherapists are not versed in fundamentals of properly performing cardiovascular screenings. This lack of knowledge is present across the profession and may impact on appropriate triage and management. The poorly executed screening has the potential to negatively impact the patient and the practitioner. Given the absence of Italian guidelines, we produced and implemented three infographics for public use, which have the dual objective of raising awareness about this subject and providing practical resources for everyday practice.

Prevalence and Associated Factors of Clinical Myelopathy Signs in Smartphone-Using University Students with Neck Pain

University students have the highest smartphone-use addiction, which coincides with a rising number in instances of neck pain. As the time in smartphone use increases, neck flexion tends to increase. These positions can affect the spinal cord by the direct and indirect mechanisms which lead to cervical myelopathy. Thus, the current study aimed to determine the prevalence and associated factors of clinical myelopathic signs in smartphone-using university students with neck pain. A total of 237 smartphone-using university students with neck pain participated in the study. They were 20 to 25 years old. Their clinical myelopathic signs were evaluated using standardized test procedures. The prevalence of the clinical myelopathic sign was the Trömner sign at 41.35%, the finger escape sign at 28.27%, Hoffmann’s sign at 25.74%, and the inverted supinator sign at 18.14%. Smartphone usage ≥9.15 h per day was associated with ≥1 of a positive clinical myelopathic sign (adjusted OR = 1.85, 95% CI = 1.05 to 3.26, p = 0.05). The current study highlighted that prolonged smartphone usage may affect the spinal cord. Long duration (≥9 h per day) was associated with at least one positive clinical myelopathic sign. Therefore, smartphone-using university students need to keep their duration of smartphone use to less than 9 h per day. More attention should be given to increasing awareness about the importance of having healthy positions when using smartphones and using them for restricted durations in order to control the increasing prevalence of cervical myelopathy among smartphone-using university student in our societies.

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.

Assessing Cranial Nerves in Physical Therapy Practice: Findings from a Cross-Sectional Survey and Implication for Clinical Practice

BACKGROUND AND OBJECTIVE

Serious pathologies of the neck can potentially result in cranial nerve palsy. Knowledge about cranial nerve examination (CNE) seems sparse, and its use is still unknown. We aim to investigate the knowledge, skills, and utilization of CNE of Italian physiotherapists.

MATERIALS AND METHODS

An online cross-sectional survey.

RESULTS

396 completed the survey, reaching the required sample size. Although Italian physiotherapists consider CNE relevant (mean ± SD = 7.6/10 ± 2.0), over half of all responders (n = 229 (57.8%)) were not trained in the fundamentals and around a third did not use it in their daily practice (n = 138 (34.8%)). Additionally, participants were unconfident and insecure in conducting (n = 152 (38.4%) and n = 147 (37.1%)), interpreting (n = 140 (35.4%) and n = 164 (41.4%)), and managing the CNE (n = 141 (35.6%) and n = 154 (38.9%)). Possessing a musculoskeletal specialization was associated with an increased value attributed to clinical practice guidelines and reduced the lack of confidence in conducting, interpreting, and managing the CNE (respectively, n = 35 (25.5%), p = 0.0001; n = 32 (23.4%) p = 0.0002; n = 32 (23.4%) p = 0.0002). Working in a direct access setting significantly increased the considered relevance of guidelines and the concerns about arterial (p = 0.004) and other serious pathologies (p = 0.021). Pain and visual disturbances were considered the main indicators to CNE, demonstrating limited knowledge of signs and symptoms' indicating CNE. Participants considered specific training in CNE as relevant (mean ± SD = 7.6/10 = 2.1).

CONCLUSIONS

a substantial proportion of Italian physiotherapists are not schooled in the fundamentals of cranial nerve examination. Given the number of physiotherapists who work in first contact roles, this is a professional concern.
