Cervicogenic dizziness: a review of diagnosis and treatment

The effect of cervical traction on stabilometric parameters in cervical radiculopathy patients: A randomized crossover study

BACKGROUND

Cervical traction is effective on pain and function in patients with cervical radiculopathy but its effectiveness on balance disorders has not yet been studied.

OBJECTIVE

To evaluate the effect of mechanical intermittent cervical traction (MICT) on stabilometric parameters in patients with cervical radiculopathy.

METHODS

This randomized crossover study assigned 20 patients with cervical radiculopathy to one of the two groups: Group effective traction (ET)/sham traction (ST) (n= 10) treated firstly with ET (traction force of 12 Kg) then with ST (traction force of 2 Kg) with one-week interval and group ST/ET (n= 10) treated invertedly with a ST then ET. Each traction procedure was maintained for 10 minutes twice separated by 5 minutes of rest. Patients were assessed before and immediately after MICT procedure. Main outcome measures were stabilometric parameters: center of pressure, sway area and lateral and anteroposterior displacements using a force platform. Secondary outcome measures were pain intensity, grip strength and dizziness.

RESULTS

ET has provided a significantly greater improvement in both groups and in the total population in terms of stabilometric parameters (p< 0.01), pain intensity, and grip strength (p< 0.05), compared to ST.

CONCLUSION

MICT seems to have an immediate beneficial effect on stabilometric parameters, pain and grip strength in patients with cervical radiculopathy.

Degenerative Cervical Spondylosis: A Cause of Vertigo?

STUDY DESIGN

Prospective observational study.

OBJECTIVES

Studying the effect of degenerative cervical spondylosis(CS) on blood flow velocity of vertebral artery (VA) during cervical spine rotation in different head positions and its association with vertigo.

INTRODUCTION

Vertigo is one of the most common complaints seen in an out-patient clinic. Its association with CS remains an enigma for a treating physician. This study planned to systematically analyze the association between vertigo and CS by evaluating VA blood flow dynamics in different head positions.

METHODS

100 patients with ages ranging from 20-80 years were recruited. First group of 50 patients with CS with vertigo were compared with second study group of 50 patients having CS without vertigo. Cervical radiographs were used to evaluate CS using cervical degenerative index (CDI). Color doppler was used to measure VA blood flow with head in neutral position and 60° lateral rotation with 30° extension. Same procedure was repeated on opposite side. Measurements performed included peak systolic blood flow velocity(PSV) and end diastolic blood flow velocity (EDV).

RESULTS

Among patients with CS, patients having vertigo showed significantly more evident degenerative changes (CDI ≥25) (P=<0.001). High grade CS patients (CDI ≥25) with vertigo had statistically significant lower blood flow parameters with head rotation in the left and right VAs as compared to CS patients without vertigo.

CONCLUSION

This study highlights important pathophysiological mechanism of vertigo observed in patients of CS. The magnitude of reduction in VA blood flow was significantly higher in patients with advanced CS presenting as vertigo.

Cervicogenic Dizziness After Self-Manipulation of the Cervical Spine

Patients with pre-existing cervical pathologies who experience dizziness and related neck pain are referred to as having cervicogenic dizziness. We describe a case of a 49-year-old female who presented with acute onset of vertigo and imbalance following self-manipulation of the cervical spine. Examination revealed a restricted cervical range of motion, muscle hypertonicity, and positive neurological signs. Radiographs demonstrated loss of normal cervical lordosis. The patient was diagnosed with cervicogenic dizziness and prescribed chiropractic treatments that included spinal manipulation, soft tissue release, and rehabilitative exercises. After four weeks of care, her symptoms had improved. At the six-month follow-up, the patient remained asymptomatic with a full cervical range of motion. This case highlights the risks associated with neck manipulation and the effectiveness of chiropractic treatment for cervicogenic dizziness. Patients should be counseled to seek evaluation and treatment from appropriate medical professionals for neck issues or dizziness/imbalance.

Vestibular, Central, and Non-Vestibular Etiologies of Vertigo and Disequilibrium: A Rural Hospital-Based Cross-Sectional Comparative Analysis

INTRODUCTION

Vertigo/dizziness is defined as disturbed postural awareness and could range from a feeling of sensation of spinning of self or surrounding. Dizziness or disturbed postural awareness is a common presentation in varying age groups. Vertigo has varied clinical presentations. Classically, there are four vertigo syndromes: vertigo, imbalance/disequilibrium, presyncope/lightheadedness, and psychogenic dizziness. The present study was conducted to examine the various etiologies involved in these syndromes and to help unmask the overlaps between them. This study also aimed to further classify the etiologies underlying these vertigo syndromes and overlaps into peripheral or vestibular, central, and non-vestibular. This would help develop a comprehensive management protocol for vertigo of any origin.

METHODS

A prospective observational cross-sectional study was undertaken in a rural hospital in Central India. We studied patients with giddiness and categorized them into vertigo syndromes according to the site of origin of vertigo. We also compared overlaps in the presentation of vertigo.

RESULTS

Out of the 80 patients that were studied, vertigo with disequilibrium was observed in 72.50% of the patients. Non-vestibular vertigo of cervicogenic origin was the common cause of vertigo seen in 36.25% of the patients occurring alone or in association with vestibular vertigo. Among patients with overlaps, vestibular vertigo with non-vestibular vertigo was the most common etiology observed in 89.65% of the patients with overlaps.

CONCLUSION

The syndrome of "vertigo with disequilibrium" was the commonest presentation in the patients studied, followed by "vertigo syndrome" as an isolated symptom, not associated with "disequilibrium." Ours is probably the first study to report this observation of overlaps of two syndromes, with diagnostic implications.

Adults are not older adolescents: comparing physical therapy findings among adolescents, young adults and older adults with persistent post-concussive symptoms

OBJECTIVE

Individuals with persistent post-concussive symptoms (PPCS) may present with a myriad of physical symptoms. There is limited research available comparing the presence of examination findings among individuals with PPCS from different age groups.

METHODS

Retrospective case-control chart review of 481 patients with PPCS and 271 non-trauma controls. Physical assessments were categorized as ocular, cervical, and vestibular/balance. Differences in presentation were compared between PPCS and controls as well as between individuals with PPCS in three age groups: adolescents, young adults, and older adults.

RESULTS

All three PPCS groups had more abnormal oculomotor findings than their age-matched counterparts. When comparing PPCS patients from different age groups, no differences were seen in prevalence of abnormal smooth pursuits or saccades; however, adolescents with PPCS had more abnormal cervical findings and a lower prevalence of abnormal NPC, vestibular and balance findings.

CONCLUSION

Patients with PPCS presented with a different constellation of clinical findings based on their age. Adolescents were more likely to demonstrate evidence of cervical injury compared to younger and older adults, and adults were more likely to present with vestibular findings and impaired NPC. Adults with PPCS were more likely to present with abnormal oculomotor findings compared to adults with non-traumatic causes of dizziness.

Proprioceptive Cervicogenic Dizziness Care Trajectories in Patient Subpopulations: A Scoping Review

Proprioceptive cervicogenic dizziness (PCGD) is the most prevalent subcategory of cervicogenic dizziness. There is considerable confusion regarding this clinical syndrome's differential diagnosis, evaluation, and treatment strategy. Our objectives were to conduct a systematic search to map out characteristics of the literature and of potential subpopulations of PCGD, and to classify accordingly the knowledge contained in the literature regarding interventions, outcomes and diagnosis. A Joanna Briggs Institute methodology-informed scoping review of the French, English, Spanish, Portuguese and Italian literature from January 2000 to June 2021 was undertaken on PsycInfo, Medline (Ovid), Embase (Ovid), All EBM Reviews (Ovid), CINAHL (Ebsco), Web of Science and Scopus databases. All pertinent randomized control trials, case studies, literature reviews, meta-analyses, and observational studies were retrieved. Evidence-charting methods were executed by two independent researchers at each stage of the scoping review. The search yielded 156 articles. Based on the potential etiology of the clinical syndrome, the analysis identified four main subpopulations of PCGD: chronic cervicalgia, traumatic, degenerative cervical disease, and occupational. The three most commonly occurring differential diagnosis categories are central causes, benign paroxysmal positional vertigo and otologic pathologies. The four most cited measures of change were the dizziness handicap inventory, visual analog scale for neck pain, cervical range of motion, and posturography. Across subpopulations, exercise therapy and manual therapy are the most commonly encountered interventions in the literature. PCGD patients have heterogeneous etiologies which can impact their care trajectory. Adapted care trajectories should be used for the different subpopulations by optimizing differential diagnosis, treatment, and evaluation of outcomes.

The efficacy of self-exercise in a patient with cervicogenic dizziness: A randomized controlled trial

Background

Cervicogenic dizziness is a clinical syndrome characterized by neck pain and dizziness. Recent evidence suggested that self-exercise could improve a patient's symptoms. The objective of this study was to evaluate the efficacy of self-exercise as an add-on therapy in patients with non-traumatic cervicogenic dizziness.

Methods

Patients with non-traumatic cervicogenic dizziness were randomly assigned to the self-exercise and control groups. The self-exercise group was instructed to perform muscle, mobilization, and oculomotor training at home while there was no specific training given to the control group. The neck pain, dizziness symptoms, and their impact on daily life were evaluated by the Dizziness Handicap Inventory (DHI) scale, the Neck Disability Index (NDI) scale, and the visual analog scale (VAS). The objective outcomes included the range of motion test of the neck and the posturography test. All outcomes were evaluated at 2 weeks after the initial treatment.

Results

A total of 32 patients participated in this study. The average age of the participants was 48 years. The DHI score of the self-exercise group after the treatment was significantly lower when compared to the control group [mean difference (MD) 25.92 points, 95% CI 4.21-47.63, p = 0.021]. The NDI score after treatment was also significantly lower in the self-exercise group (MD 6.16 points, 95% CI 0.42-11.88, p = 0.036). However, there was no statistical difference in the VAS score, the range of motion test, and the posturography test between the two groups (p > 0.05). No significant side effects were noted in either of the groups.

Conclusion

Self-exercise is effective in reducing dizziness symptoms and its impact on daily life in patients with non-traumatic cervicogenic dizziness.

Suboccipital Muscles, Forward Head Posture, and Cervicogenic Dizziness

Dizziness or vertigo can be caused by dysfunction of the vestibular or non-vestibular systems. The diagnosis, treatment, and mechanism of dizziness or vertigo caused by vestibular dysfunction have been described in detail. However, dizziness by the non-vestibular system, especially cervicogenic dizziness, is not well known. This paper explained the cervicogenic dizziness caused by abnormal sensory input with references to several studies. Among head and neck muscles, suboccipital muscles act as stabilizers and controllers of the head. Structural and functional changes of the suboccipital muscles can induce dizziness. Especially, myodural bridges and activation of trigger point stimulated by abnormal head posture may be associated with cervicogenic dizziness.

Proprioceptive Cervicogenic Dizziness: A Narrative Review of Pathogenesis, Diagnosis, and Treatment

Basic science and clinical evidence suggest that cervical spine disorders can lead to dizziness. The cervical spine has highly developed proprioceptive receptors, whose input information is integrated with the visual and vestibular systems in the central nervous system, acting on the neck and eye muscles to maintain the coordinative motion of the head, eyes, neck, and body through various reflex activities. When the cervical proprioceptive input changes due to the mismatch or conflict between vestibular, visual, and proprioceptive inputs, cervicogenic dizziness may occur. The diagnosis of cervicogenic dizziness can be determined based on clinical features, diagnostic tests, and the exclusion of other possible sources of dizziness. The cervical torsion test appears to be the best diagnostic method for cervicogenic dizziness. Based on the available evidence, we first developed the diagnostic criteria for cervicogenic dizziness. Treatment for cervicogenic dizziness is similar to that for neck pain, and manual therapy is most widely recommended.

Clinical characteristics and diagnostic aspects of cervicogenic dizziness in patients with chronic dizziness: A cross-sectional study

BACKGROUND AND OBJECTIVES

Chronic dizziness can significantly affect quality of life, but identifying the underlying cause remains challenging. This study focuses on proprioceptive cervicogenic dizziness (CGD) and aims: (1) to compare clinical test results between patients with CGD, dizzy patients without CGD, and healthy controls; and (2) to evaluate the diagnostic value of the clinical tests for CGD in patients with chronic dizziness.

METHODS

Sixty patients with chronic dizziness (18 with CGD and 42 without CGD), and 43 healthy controls underwent clinical tests evaluating neck function (mobility, proprioception, muscle function and disability), balance control, and the presence of visually induced dizziness. Data were analysed through one-way ANOVA, chi-square, independent samples t-test, and logistic regression analyses.

RESULTS

Patients with CGD had significantly more neck pain-related disability (Neck Bournemouth questionnaire (NBQ), p = 0.006), but better static (Static Balance, p = 0.001) and dynamic balance (Tandem Gait, p = 0.049), compared to dizzy patients without CGD. Univariable analyses revealed that increased NBQ (OR 1.05 [1.01; 1.09], p = 0.017), Joint Position Error (JPE) _{after extension} (OR 1.52 [1.00; 2.32], p = 0.050), and Tandem Gait scores (OR 1.09 [1.01; 1.18], p = 0.046) were individually associated with higher odds of having CGD. Their optimal cut-off level (based on the maximum Youden index) had high sensitivity but low specificity for CGD. The multivariable model, including NBQ and Tandem Gait, had fair discriminative ability (AUC = 0.74, 95% CI [0.61; 0.87]).

CONCLUSION

The combined use of the NBQ and Tandem Gait tests had the highest discriminative ability to detect CGD in patients with chronic dizziness.

Central vestibular dysfunction: don't forget vestibular rehabilitation

INTRODUCTION

Vestibular rehabilitation (VR) is now a subject of active studies and has been shown to be effective for multiple vestibular disorders, peripheral or central. VR is a physical therapy that helps train the central nervous system to compensate for vestibular dysfunction. There is moderate to strong evidence that VR is safe and effective for the management of peripheral vestibular dysfunction. Nonetheless, the studies on how VR works on central vestibular dysfunction remains scanty.

AREAS COVERED

This article addressed the rehabilitation strategies and possible mechanisms, including how central vestibular function might improve upon rehabilitation. In addition, it provides some examples concerning the effect of VR on central vestibular dysfunction.

EXPERT OPINION

VR works on the vestibular system through repetition of specific physical exercises that activate central neuroplastic mechanisms to achieve adaptive compensation of the impaired functions. VR has become a mainstay in the management of patients with dizziness and balance dysfunction. Individualized VR programs are a safe and effective treatment option for a large percentage of patients with central vestibular disease reporting imbalance and dizziness. Exploration of various treatment strategies and possible mechanisms will help develop the best and personalized VR treatment for patients with central vestibular dysfunction.

Combination of Two Manipulative Techniques for the Treatment of Cervicogenic Dizziness: A Randomized Controlled Trial

Cervicogenic dizziness is clinically associated with upper cervical spine dysfunctions. It seems that manual therapy decreases the intensity of dizziness in these subjects, but what happens to pain measured by pressure pain threshold (PPT) has not been studied. Purpose: analyze the short-term effects of combination two manipulation techniques protocol in worst dizziness intensity (wVAS), dizziness and cervical disability, upper cervical spine mobility and mechanosensivity of cervical tissue. Methods: Assessor-blinded randomized controlled trial was developed. A total of 40 patients with cervicogenic dizziness were randomly divided into two groups. The experimental group received three treatments consisting of a functional massage and a manipulation technique, and compared with a control group. The wVAS, dizziness handicap inventory (DHI), neck disability index (NDI), UCS mobility, and PPTs were measured. Measurements were made at the baseline, first follow-up 48 h after intervention and second follow-up 1 month after the intervention. Results: at second follow-up wVAS (p < 0.001), NDI (p < 0.001), DHI (p < 0.001), and upper right trapezius (p < 0.022) and right suboccipital (p < 0.043) PPTs showed a difference between groups in favor of the experimental group. Conclusions: apparently, the proposed intervention protocol decreases the intensity of dizziness and the mechanosensitivity of the cervical tissue and improves the feeling of disability due to neck pain and dizziness.

Chinese Herbal Medicine for Cervicogenic Dizziness: A Systematic Review and Meta-Analysis

Background

Chinese herbal medicines (CHMs) have been widely used in the treatment of cervicogenic dizziness (CGD) based on their empirical effectiveness and safety. Herein, we reviewed and evaluated the clinical evidence of the efficacy and safety of CHMs for CGD.

Methods

Among the relevant studies published in 11 electronic databases up to December 2021, only randomised controlled trials were included. Methodological quality was assessed using the revised Cochrane risk-of-bias tool for randomised trials, and the strength of evidence for the main outcomes was evaluated using the grading of recommendations assessment, development, and evaluation system.

Results

All 35 included randomised controlled trials with 3,862 participants were conducted with six types of modified CHM and four types of active controls. More than half of the included studies were of low quality because of the high risk of bias due to deviations from intended interventions. CHM plus active control was more effective in the treatment of CGD than active control alone. CHM plus anti-vertigo drugs, CHM plus manual therapy, CHM plus acupuncture therapy, and CHM plus manual and acupuncture therapy were all effective in treating CGD, with CHM plus manual and acupuncture therapy showing the most reliable effect. All CHMs were effective for specific patterns of CGD when administered with active controls, with Dingxuan Tang and Yiqi Congming Tang demonstrating the most reliable effects. No serious adverse events were reported in any of the included studies.

Conclusion

The current evidence suggests that CHM may enhance the treatment of CGD when combined with other treatments without serious adverse events. Further high-quality evidence is needed to draw definitive conclusions.

Systematic review and meta-analysis of the therapeutic management of patients with cervicogenic dizziness

BACKGROUND

Patients with cervicogenic dizziness (CGD) present with dizziness, cervical spine dysfunctions, and postural imbalance, symptoms that can significantly impact their daily functioning.

OBJECTIVES

To provide evidence-based recommendations for the management of patients with CGD.

METHODS

Three databases were searched for randomized controlled trials (RCTs) (last search 15 May 2021). Outcome measures included dizziness, cervical spine, and balance parameters. Cochrane standard methodological procedures were used and included the RoB 2.0 and GRADE. Where possible, RCTs were pooled for meta-analysis.

RESULTS

Thirteen RCTs (n = 898 patients) of high (two RCTs), moderate (five RCTs), and low (six RCTs) methodological quality were analyzed. Six RCTs were included in the meta-analysis. Only three RCTs specified the cause of CGD. They showed inconsistent findings for the effectiveness of exercise therapy in patients with traumatic CGD. Manual therapy and manual therapy combined with exercise therapy may reduce CGD, cervical spine, and balance dysfunctions.

CONCLUSION

There is moderate quality of evidence that manual therapy reduces CGD, cervical spine, and balance symptoms. When manual therapy is combined with exercise therapy, the positive effect on CGD, cervical spine, and balance symptoms is even stronger. However, the quality of the evidence here is very low.

Translation and Validation of the Dizziness Handicap Inventory into Thai Language

OBJECTIVE

To translate and evaluate psychometric properties of Thai version of the Dizziness Handicap Inventory (DHI-TH).

STUDY DESIGN

A cross-sectional study.

SETTING

Ambulatory.

PATIENTS

Fifty patients with dizziness at a vestibular clinic.

MAIN OUTCOME MEASURES

Translation and cross-cultural adaptation of the original English version of the DHI was performed according to published guidelines. Psychometric evaluation included internal consistency, content validity, test-retest reliability, convergent validity, discriminant ability, and responsiveness. Responsiveness was examined in 28 patients with vestibular dysfunction who received vestibular rehabilitation for 6 to 8 weeks.

RESULTS

There were no floor and ceiling effects. The Cronbach's alpha was good for the total score (0.87) and subscale scores (0.70 physical, 0.73 emotional, and 0.71 functional). Excellent test-retest reliability was demonstrated for the total and subscales (ICC ranged from 0.91 to 0.97, p < 0.001). The SEM was 3.50 and the MDC was 9.68. The total and subscales of DHI-TH were moderately correlated with the SF-36-TH scores (r ranged from -0.40 to -0.63). An optimal cut-off point for detection of dizziness was 21 points (98% sensitivity, 94% specificity). Responsiveness of the DHI-TH was excellent. The ES and SRM were large (1.25 and 1.59, respectively). The DHI-TH discriminated well between patients with self-perceived improved dizziness versus unchanged dizziness (AUC = 0.87). The MCID was 17 points (82.0% sensitivity, 82.0% specificity).

CONCLUSION

The DHI-TH demonstrated good psychometric properties for patients with dizziness. The DHI-TH is a valid and reliable instrument recommended as a measure of disability and quality of life in Thai patients with dizziness.

The Enduring Controversy of Cervicogenic Vertigo, and Its Place among Positional Vertigo Syndromes

The idea of cervicogenic vertigo (CV) was proposed nearly a century ago, yet despite considerable scrutiny and research, little progress has been made in clarifying the underlying mechanism of the disease, developing a confirmatory diagnostic test, or devising an appropriately targeted treatment. Given the history of this idea, we offer a review geared towards understanding why so many attempts at clarifying it have failed, with specific comments regarding how CV fits into the broader landscape of positional vertigo syndromes, what a successful diagnostic test might require, and some practical advice on how to approach this in the absence of a diagnostic test.

Nonvestibular Dizziness

Dizziness is a common chief complaint with an extensive differential diagnosis that ranges from peripheral, central, to nonvestibular conditions. An understanding of nonvestibular conditions will aid accurate diagnosis and initiation of appropriate management. Thus, the objective of this article is to present an overview of nonvestibular etiologies that may plague a dizzy patient and the recommended treatment options.

An upper cervical spine treatment protocol for cervicogenic dizziness: a randomized controlled trial

INTRODUCTION

Physiotherapy is a common treatment used for cervicogenic dizziness (CD). Treatment of the cervical spine using manual therapy techniques shows moderate evidence in favor of its use. International criteria for the treatment of the cervical spine have been described. Detecting patients' contraindications is the most important safety consideration. International criteria and recommendations for treatment of the cervical spine have been described, as well as safety criteria. A safe traction-manipulation intervention protocol is therefore possible. However, the effects of this protocol on dizziness intensity and dizziness-related disability have not been studied.

OBJECTIVE

To analyze the effects of a traction-manipulation protocol in patients with CD.

METHODS

The patients were referred by an otoneurologist, and after inclusion were randomly divided into a control group and an intervention group. The intervention was based on the application of a traction-manipulation protocol in the resting position. Dizziness intensity, self-reported disability, and cervical range of motion with and without a fixed gaze were assessed. All data were collected beforehand and at two days and four weeks after intervention.

RESULTS

At the two-days follow-up, statistically significant differences in favor of the intervention were observed between groups in the primary outcomes of dizziness intensity (p < .001) and Dizziness Handicap Inventory (p < .001), and at the four-week follow-up in dizziness intensity (p < .001) and Dizziness Handicap Inventory (p < .001).

CONCLUSIONS

The traction-manipulation protocol reduces the intensity of dizziness, the patient's self-perceived disability, and improves cervical mobility with and without fixed gaze.

Vertigo: Streamlining the Evaluation through Symptom Localization

Vertigo is defined as the illusion of internal or external motion. The evaluation of a patient with vertigo in the primary care setting should not necessarily focus on providing a specific diagnosis. Rather, the physician should aim to localize the lesion. This practice streamlines the workup of patients. This article provides detailed information regarding appropriate organ system-based clinical history and the clinical workup of vertigo. Additional signs and symptoms that can facilitate appropriate referral and treatment are highlighted. Although disorder-specific treatments exist the mainstay of therapy for vertigo-induced pathology is physical therapy.

Vestibular Physical Therapy and Fall Risk Assessment

Vestibular physical therapy (VPT) is a specialized form of evidence-based therapy designed to alleviate primary (vertigo, dizziness, imbalance, gait instability, falls) and secondary (deconditioning, cervical muscle tension, anxiety, poor quality of life, fear of falling/fear avoidance behavior) symptoms related to vestibular disorders. This article provides an overview of VPT, highlighting various exercise modalities used to treat a variety of vestibular disorders. Patient safety and fall prevention are paramount; therefore, fall risk assessment and treatment are also addressed.

Positional Vertigo

Positional vertigo is a complex symptom that may arise from several disorders. In this chapter, we define positional vertigo and provide a comprehensive review of the disorders in the differential diagnosis, including benign paroxysmal positional vertigo, central paroxysmal positional vertigo, cervical vertigo and vertebrobasilar insufficiency, and persistent postural perceptual dizziness.

Dizziness and localized pain are often concurrent in patients with balance or psychological disorders

Background and aims Symptoms of dizziness and pain are both common complaints and the two symptoms often seem to coincide. When symptoms appear concomitant for sustained periods of time the symptoms might maintain and even exacerbate each other, sometimes leading to psychological distress. In order to evaluate such comorbidity we studied patients referred to a vestibular unit and to a psychiatric outpatient clinic with respectively balance disorders and psychological issues. Methods Consecutive patients referred to a vestibular unit (n = 49) and a psychiatric outpatient clinic (n = 62) answered the Dizziness Handicap Inventory (DHI) questionnaire and a questionnaire detailing occurrence of dizziness and pain. Results The experience of dizziness and pain often coincided within individuals across both clinical populations, especially if the pain was located to the neck/shoulder or the back (p = 0.006). Patients who reported dizziness had significantly more often pain (p = 0.024); in the head (p = 0.002), neck/shoulders (p = 0.003) and feet (p = 0.043). Moreover, patients who reported dizziness stated significantly higher scoring on emotional (p < 0.001) and functional (p < 0.001) DHI sub-scales. Furthermore, patients who reported an accident in their history suffered significantly more often from dizziness (p = 0.039) and pain (p < 0.001); in the head (p < 0.001), neck/shoulders (p < 0.001) and arms (p = 0.045) and they scored higher on the emotional (p = 0.004) and functional (p = 0.002) DHI sub-scales. Conclusions The findings suggest comorbidity to exist between dizziness and neck/shoulder or back pain in patients seeking health care for balance disorders or psychological issues. Patients suffering from dizziness and pain, or with both symptoms, also reported higher emotional and functional strain. Thus, healthcare professionals should consider comorbidity when determining diagnosis and consequent measures. Implications Clinicians need to have a broader "receptive scope" in both history and clinical examinations, and ask for all symptoms. Although the patients in this study visited a vestibular unit respectively a psychological clinic, they commonly reported pain conditions when explicitly asked for this symptom. A multimodal approach is thus to favor, especially when the symptoms persist, for the best clinical management.

Short-term effects of an upper cervical spine traction-manipulation program in patients with cervicogenic dizziness: A case series study

BACKGROUND

Damage on the somatosensory system could cause sensation of dizziness, a condition known as cervicogenic dizziness (CD). Manual physical therapy has shown beneficial effects, relieving the symptoms of cervicogenic dizziness. However, the effect of upper cervical spine manipulation is unknown, as this is a technique that respects the International Federation of Orthopedic Manipulative Physical Therapists (IFOMPT) safety criteria.

OBJECTIVE

To assess the effects of upper cervical spine traction-manipulation in subjects with cervicogenic dizziness.

METHODS

This was a descriptive case series study. Treatment focused on the upper cervical spine manipulation procedure. Evaluation was performed before and after the treatment. Variables recorded include upper and lower cervical range of motion, Cervical Flexion-Rotation Test (CFRT), dizziness intensity and cervical pain (VAS), self-perceived dizziness measured with Dizziness Handicap Inventory (DHI) and subjective perception of outcome (GROC-scale).

RESULTS

Ten subjects were recruited. After the treatment protocol, there was an increased range of movement towards the most restricted side, as measured by the CFRT (p< 0.001), decreased intensity of dizziness (p< 0.001) and intensity of pain (p< 0.001). Functional capacity also improved after the intervention (p< 0.011).

CONCLUSION

Upper cervical spine manipulation may decrease dizziness intensity and cervical pain and improve functional ability and upper cervical spine mobility in patients with cervicogenic dizziness.

Postural and clinical outcomes of sustained natural apophyseal glides treatment in cervicogenic dizziness patients: A randomised controlled trial

OBJECTIVE

To evaluate how self-report and posturographic measures could be affected in patients with cervicogenic dizziness undergoing sustained natural apophyseal glides.

DESIGN

Randomised controlled single-blind study.

SETTING

Tertiary rehabilitation centre.

SUBJECTS

Patients affected by cervicogenic dizziness, diagnosed by applying accepted criteria. Forty-one patients (19 male, 22 female: mean age 44.3 ± 14.8 years) receiving treatment, and 39 patients (18 male, 21 female: mean age 43.8 ± 13.9 years) receiving placebo were included in the study.

INTERVENTIONS

The treatment group underwent sustained natural apophyseal glides, while the placebo was constituted by a detuned laser. Both groups received their interventions six times over 4 weeks.

MAIN MEASURES

Outcomes were tested by means of self-report measures such as perceived dizziness, neck disability, anxiety and depression. Also, cervical range of motion and posturography testing with power spectra frequency were analysed.

RESULTS

When compared to placebo, treated patients demonstrated a significant decrease in perceived dizziness (post-treatment total Dizziness Handicap Inventory score 20.5 ± 5.3 as compared to 26.2 ± 6 baseline), neck disability and pain (Neck Disability Index and Neck Pain Index post-treatment scores 12.5 ± 4.3 and 45.6 ± 15.1, respectively, as compared to baseline scores of 15.1 ± 4.8 and 62.5 ± 14.3), as well as significant improvement in cervical range of motion and some posturographic parameters.

CONCLUSION

Sustained natural apophyseal glides may represent a useful intervention in reaching short-term beneficial effects in patients with cervicogenic dizziness, with respect to self-perceived symptoms, proprioceptive integration and cervical range of motion improvement.

Usefulness of postural sway spectral analysis in the diagnostic route and clinical integration of cervicogenic and vestibular sources of dizziness: A cross-sectional preliminary study

BACKGROUND

Posturography power spectra (PS) implementation has been proven to discriminate between sensory inputs detriment of vestibular and proprioceptive origin.

OBJECTIVE

To deepen the role of posturography testing in the diagnostic route of dizzy conditions, by comparing two groups of patients -93 affected by cervicogenic dizziness (CGD) and 72 by unilateral vestibular hypofunction (UVH) -with a group of 98 age- and gender-matched healthy subjects, serving as control group (CON).

METHODS

All participants underwent otoneurological testing including video head impulse test (vHIT) and posturography testing with PS analysis. They also filled in Dizziness Handicap Inventory (DHI), Tampa Scale for Kinesiophobia and Hospital Anxiety and Depression Scale questionnaires.

RESULTS

UVH and CGD patients were found to have significant increase in vestibular- and proprioceptive-related PS values when compared with CON. Receiver operating characteristic curves found PS values to reliably discriminate both groups from CON. Positive and negative correlations were respectively found between vestibular-/proprioceptive-related PS domain and DHI in both groups and between PS and vHIT scores in UVH patients.

CONCLUSIONS

PS analysis demonstrated to be useful in differentiating CGD and UVH patients each other and when compared to CON, to objectively represent perceived symptoms filled along the DHI scale and to corroborate the rate of vestibular deficit in UVH patients.

Cervical intervertebral disc degeneration and dizziness

Clinical studies have found that patients withcervical degenerative disease are usually accompanied by dizziness. Anterior cervical surgery can eliminate not only chronic neck pain, cervical radiculopathy or myelopathy, but also dizziness. Immunohistochemical studies show that a large number of mechanoreceptors, especially Ruffini corpuscles, are present in degenerated cervical discs. The available evidence suggests a key role of Ruffini corpuscles in the pathogenesis of dizziness caused by cervical degenerative disease (i.e. cervical discogenic dizziness). Disc degeneration is characterized by an elevation of inflammatory cytokines, which stimulates the mechanoreceptors in degenerated discs and results in peripheral sensitization. Abnormal cervical proprioceptive inputs from the mechanoreceptors are transmitted to the central nervous system, resulting in sensory mismatches with vestibular and visual information and leads to dizziness. In addition, neck pain caused by cervical disc degeneration can play a key role in cervical discogenic dizziness by increasing the sensitivity of muscle spindles. Like cervical discogenic pain, the diagnosis of cervical discogenic dizziness can be challenging and can be made only after other potential causes of dizziness have been ruled out. Conservative treatment is effective for the majority of patients. Existing basic and clinical studies have shown that cervical intervertebral disc degeneration can lead to dizziness.

Short-term effects of the traction-manipulation protocol in dizziness intensity and disability in cervicogenic dizziness: a randomized controlled trial

PURPOSE

Analyse the short-term effects of traction-manipulation protocol in dizziness and pain intensity and disability, cervical mobility and postural instability.

MATERIALS AND METHODS

Randomized controlled assessor-blind clinical trial. The traction-manipulation protocol was carried out in the intervention group and compared with a control group where the subjects were kept supine. The intervention protocol follows the IFOMPT safety recommendations. Dizziness and pain intensity, Dizziness Handicap Inventory (DHI), cervical mobility and balance were measured after 48 h and a one-month follow-up.

RESULTS

Forty subjects with cervicogenic dizziness were randomly assigned to an intervention or control group. Significant differences were found in favour of the intervention protocol group in: dizziness intensity (p < 0.001; d = 1.31), DHI (p < 0.001; d = 0.76) pain intensity (p < 0.007; d = 0.92), upper cervical flexion (p < 0.032; d = 0.30) and extension (p < 0.012; d = 0.80) at 48 h follow up. At one-month follow up there were significant differences in favour of the intervention group in: dizziness intensity (p < 0.001; d = 0.95), DHI (p < 0.001; d = 0.0.92) pain intensity (p < 0.001; d = 1.38) and upper cervical extension (p < 0.005; d = 0.92). Postural instability improved in mediolateral displacement static with eyes closed (p < 0.032; d = 0.79) and in dynamic with eyes open (p = 0.003; d = 0.55) at one-month follow-up in the intervention group.

CONCLUSION

The traction-manipulation protocol reduces the dizziness and pain intensity, ameliorates disability and improves upper cervical mobility and postural instability.IMPLICATIONS FOR REHABILITATIONThe intervention protocol reduces the dizziness and pain intensity, and improves self-perceived disability in patients with cervicogenic dizziness.Manual therapy improves the cervical range of motion and the postural instability in the cervicogenic dizziness.The intervention protocol follows the safety recommendations of the International Federation of Orthopaedic Manipulative Physical Therapists.

Herbal medicine for cervicogenic dizziness: A protocol for a systematic review and meta-analysis

BACKGROUND

Herbal medicines are empirically used to treat cervicogenic dizziness. However, till date there have been no systematic review to evaluate the efficacy and safety of these medicines. Therefore, this study protocol describes the methods for evaluating the efficacy and safety of herbal medicine for cervicogenic dizziness.

METHODS AND ANALYSIS

The following electronic academic databases will be searched up to December 2019 without language or publication status restrictions: Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), and the Cochrane Central Register of Controlled Trials (CENTRAL), together with Korean, Chinese, and Japanese databases. Any randomized controlled trials related to herbal medicine for cervicogenic dizziness will be included. The functional outcomes and the vertebrobasilar artery hemodynamic states will be evaluated as primary outcomes. The total effective rate, hematological conditions, and adverse events will be assessed as secondary outcomes. Study selection, data extraction, quality assessment of studies, and qualitative evaluation of clinical evidence will be performed by 2 independent reviewers. The methodological quality of the included studies will be evaluated using a revised Cochrane risk-of-bias tool for randomized trials. The strength of evidence from the included data will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation approach. Data synthesis will be performed as either a fixed-effects or a random-effects model using Review Manager software version 5.3. The results will be reported as a risk ratio for dichotomous outcomes and as a mean difference or standardized mean difference for continuous outcomes.

ETHICS AND DISSEMINATION

No ethical approval is required since the individual clinical information of the patient is not used. The findings of this systematic review will be disseminated through the peer-reviewed publications or conference presentations.

Upper cervical spine dysfunction and dizziness

Although various causes of dizziness have been identified, many patients suffer from dizziness of unknown etiology and continue to visit hospitals to resolve their symptoms. Problems that occur in the ligaments or muscles of the upper cervical spine can cause confusion in proprioception. These changes can convey misinformation to the vestibular nucleus, resulting in abnormal reactions that can lead to cervicogenic dizziness (CGD). Though CGD remains controversial, it should be considered while diagnosing patients with dizziness. Understanding CGD can help create treatment strategies for them. This article suggested a relationship between the structure and function of the upper cervical spine and dizziness, and presented evaluations and treatments for the same.

Bridging the gap between temporomandibular disorders, static balance impairment and cervicogenic dizziness: Posturographic and clinical outcomes

Several studies have investigated the possible influence of temporomandibular disorders (TMD) on body posture and whether cervical spine disorders, such as cervicogenic dizziness (CGD) could play an additional role in affecting static balance. The purpose of this study was to analyze static postural behavior by means of static posturography, in patients affected by either TMD or CGD alone or by both conditions, and to compare findings with a group of healthy subjects. Significant changes in posturographic parameters were found among the three groups of patients and when compared with controls. When the three study groups were compared to each other, subjects affected by a combination of TMD and CGD showed worse postural performances with respect to subjects affected by CGD or TMD alone. Correlations with self-perceived dizziness, anxiety, depression and jaw functionality, investigated by means of validated questionnaires, were found among all patient groups. These results provide new evidences for the presence of static balance alterations in patients suffering from TMD with and without associated cervical spine impairment, by using a reliable diagnostic technique. Further studies are needed in order to identify any causal relation between these two disorders.

Revisiting "Meniere's Disease" as "Cervicogenic Endolymphatic Hydrops" and Other Vestibular and Cervicogenic Vertigo as "Spectrum of Same Disease": A Novel Concept

Vertigo and dizziness are one of the commonest and least understood symptom. Vestibular vertigo of Meniere's disease and Benign Paroxysmal positional vertigo (BPPV) and cervicogenic dizziness are classified as separate entities. Cervicogenic dizziness is not considered the domain of Otolaryngologists, as it is mainly related to neck proprioceptors. Headache and neck pain, have been found to be associated with both Meniere's disease and BPPV, so is cervicogenic dizziness. The present study was undertaken to study the association between cervical signs and symptoms in patients with Vestibular Vertigo of Meniere's disease, Benign Paroxysmal Positional Vertigo and cervicogenic dizziness. 132 patients complaining of vertigo and diagnosed with Meniere's disease, BPPV or cervicogenic dizziness were examined for symptoms and signs related to neck, shoulder and muscle tightness and asymmetry. Most of the patients of Meniere's Disease (80% for unilateral and 88.23% for bilateral), Benign Paroxysmal Positional Vertigo (75%for right sided BPPV, 66.67% for left sided BPPV) and cervicogenic dizziness (90%) had associated symptoms of neck pain or headache, and were found to be positive for neck tightness and/or asymmetry of shoulder. Headache was more common in patients with Meniere's Disease. Vestibular Dizziness of Meniere's Disease, Benign Paroxysmal Positional Vertigo and Cervicogenic Dizziness may be spectrum of the same disease with underlying myofascial problems. Meniere's Disease of Idiopathic or primary type needs to be revisited as Cervicogenic Hydrops.

Physical therapy interventions for cervicogenic dizziness in a military-aged population: protocol for a systematic review

BACKGROUND

Traumatic cervicogenic dizziness is dizziness that is temporally associated with neck pain and injury after other causes of dizziness have been excluded. It can lead to activity limitations and participation restrictions that may include lost duty or work days. The objective of this systematic review is to determine which interventions are most effective in decreasing dizziness or vertigo and neck pain in military-aged adults with traumatic cervicogenic dizziness.

METHODS

The literature will be systematically searched using the following online databases: MEDLINE, EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, CENTRAL, Cochrane Methodology Register), CINAHL, SCOPUS, Web of Science, and J-STAGE. The review will include randomized controlled trials (RCTs), including cluster RCTs and controlled (non-randomized) clinical trials or cluster trials, and observational studies (including prospective and retrospective comparative cohort and case-control or nested case-control studies) and determine the effectiveness of physical therapy interventions for the treatment of traumatic cervicogenic dizziness in military-aged adults. Assessment of methodological quality will be performed by two independent, blinded reviewers using the PEDro scale. The level of evidence will be determined using the GRADE scale. The primary outcome measures will be change in dizziness and neck pain and disability from baseline to the last available follow-up, measured using the Dizziness Handicap Inventory and Neck Disability Index. Other relevant outcome measures will include self-reported change in symptoms, time to return to duty or work, and quality of life.

DISCUSSION

This systematic review will identify, evaluate, and integrate the evidence on the effectiveness of physical therapy interventions for cervicogenic dizziness in a military-aged population. We anticipate our findings may inform individual treatment and future research. Clinical recommendations generated from this systematic review may inform military physical therapy treatment of individuals with cervicogenic dizziness.

SYSTEMATIC REVIEW REGISTRATION

In accordance with the guidelines, our systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) on 21 January 2020 (registration number CRD42020150853). In the event of protocol amendments, the date of each amendment will be accompanied by a description of the change and the rationale.

Cervicogenic exophthalmos: Possible etiology and pathogenesis

BACKGROUND

Unilateral exophthalmos is often caused by inflammation, neoplasm, infection, metabolic disease, vascular disorder and several other less common conditions. Reflex sympathetic dystrophy related to unilateral exophthalmos has not been reported in the past literature.

CASE SUMMARY

We describe a 45-year-old female with unilateral exophthalmos caused by reflex sympathetic dystrophy and its unexpected spontaneous disappearance after a standard anterior cervical discectomy and fixation operation with two PEEK interbody cages and a plate. To our surprise, the patient’s left unilateral exophthalmos improved spontaneously in the morning on postoperative day 2-with no relapse, without any further medication, as of seven years. We have named this condition “cervicogenic exophthalmos.”

CONCLUSION

We would inform other clinicians that unilateral exophthalmos was caused not only by inflammation, vascular disorder, infection, neoplasm, or metabolic disease, but also by reflex sympathetic dystrophy related with cervicogenic spondylosis. To the best of our knowledge, ours is the first related case report and use of the term “cervicogenic exophthalmos” after reviewing previous literature.

Normative Responses to Clinical Tests for Cervicogenic Dizziness: Clinical Cervical Torsion Test and Head-Neck Differentiation Test

BACKGROUND

The clinical diagnosis of cervicogenic dizziness (CGD) is challenging because of a lack of sensitive and specific diagnostic tests. It is vital for clinicians to know normative responses to suggested clinical tests to help them develop the method and interpretation of these tests and maximize their diagnostic value for CGD.

OBJECTIVE

The purpose of the study was to determine normative responses to the clinical application of the cervical torsion test and the head-neck differentiation test, with consideration of different age groups and sex.

DESIGN

This was an observational study.

METHODS

One hundred forty-seven people who were healthy and asymptomatic served as controls and performed both tests, which involved 3 components: cervical torsion, cervical rotation, and en bloc rotation (head and trunk rotation together).

RESULTS

Thirty-five (23.81%) of the 147 participants reported some symptoms (mild dizziness, visual disturbances, unusual eye movements on opening eyes after the test, motion sickness, or nausea) on 1 or more of the 3 test components in either test. The specificity when using a positive response to torsion alone (ie, a negative response to the rotation or en bloc component) was high (for the cervical torsion test, 98.64%; for the head-neck differentiation test, 89.8%), as participants with likely global sensorimotor sensitivity were eliminated. The combined specificity was 100%, as no participants presented with exclusive positive torsion results in both tests. Age and sex did not influence the results.

LIMITATIONS

There were several examiners who were not blinded.

CONCLUSIONS

Confirmation of the high specificity of these clinical tests with the method used in this study to conduct and interpret the results will allow future research to determine the sensitivity of these clinical measures in a population with CGD and specificity in those with dizziness of other origins.

A new treatment for cervical vertigo with botulinum toxin

A new and unique treatment for cervical vertigo with botulinum toxin is presented for a woman who sustained neck trauma from being hit by a wave. A diagnosis of cervical vertigo and cervical dystonia was confirmed by history, physical exam, dystonia on EMG exam, and a negative test for benign paroxysmal positional vertigo. She experienced consistent resolution of her vertigo symptoms and pain after each treatment for a total of 5 treatments with botulinum toxin to the upper cervical muscles.This report appears to be the first to demonstrate the missing link between vertigo and cervical dystonia with pain. Chemodenervation was effective in treating cervical vertigo and is likely to have altered the cervical proprioceptive input by relaxing the overactive muscles and/or by decompression of cervical nerves.

Cervicogenic dizziness

Cervical muscles have numerous connections with vestibular, visual and higher centres, and their interactions can produce effective proprioceptive input. Dysfunction of the cervical proprioception because of various neck problems can alter orientation in space and cause a sensation of disequilibrium. Cervicogenic dizziness (CGD) is a clinical syndrome characterized by the presence of dizziness and associated neck pain in patients with cervical pathology. Here, we report a 24-year-old female, who was diagnosed with CGD based on the correlating episodes of neck pain and dizziness. Both symptoms improved with targeted chiropractic adjustment and ultrasound therapy. CGD is a seemingly simple complaint for patients, but tends to be a controversial diagnosis because there are no specific tests to confirm its causality. For CGD to be considered, an appropriate management for the neck pain should not be denied any patient.

Neck pain associated with clinical symptoms in dizzy patients-A cross-sectional study

OBJECTIVE

Many patients suffer from concurrent neck pain and dizziness. The aim of this study was to describe the clinical symptoms and physical findings in patients with concurrent neck pain and dizziness and to examine whether they differ from patients with dizziness alone.

METHODS

Consecutive patients with dizziness and neck pain were recruited from an ear-nose-throat department and a spine clinic. They were divided into three groups: patients with dizziness only (n = 100), patients with dizziness as their primary complaint and additional neck pain (n = 138) and finally, patients with neck pain as their primary complaint accompanied by additional dizziness (n = 55). The patients filled in questionnaires regarding their symptom quality, time-course, triggers of dizziness and the Vertigo Symptom Scale Short Form. The physical examination included Cervical Range of Motion, American College of Rheumatology (ACR) Tender Points, Cervical Pressure Pain Thresholds and Global Physiotherapy Examination 52-Flexibility.

RESULTS

Both neck pain groups were more likely to have a gradual onset of dizziness symptoms, more light-headedness, visual disturbances, autonomic/anxiety symptoms, decreased cervical range of motion, decreased neck and shoulder flexibility and increased number of ACR tender points compared with patients with dizziness alone. The group having dizziness as their primary complaint and also reporting neck pain had the highest symptom severity and tended to report rocking vertigo and increased neck tenderness. The group with neck pain as their primary complaint was more likely to report headache.

CONCLUSION

Neck pain is associated with certain dizziness characteristics, increased severity of dizziness and increased physical impairment when compared with dizzy patients without neck pain.

Diagnostic route of cervicogenic dizziness: usefulness of posturography, objective and subjective testing implementation and their correlation

PURPOSE

To evaluate posturography measurements, and their association with other clinical tests used for cervicogenic dizziness diagnosis, in a cohort of subjects suffering from cervicogenic dizziness, compared with healthy subjects.

MATERIALS AND METHODS

Ninety-three cervicogenic dizziness patients and 98 age- and gender-matched healthy subjects underwent video-Head impulse test, posturography testing, evaluation of cervical spine movements by means of cervical range of motion goniometer and self-report and performance measures, including Dizziness Handicap Inventory, Neck Disability Index, Neck Pain Intensity, Tampa Scale for Kinesiophobia and Hospital Anxiety and Depression Scale.

RESULTS

Cervicogenic dizziness patients demonstrated significant increases in classical posturography parameters (i.e., surface and length) and in power spectra values within middle and high-frequency interval depicting balance control alterations especially due to proprioceptive integration changes. Furthermore, decreases in degrees of cervical range of motion and increases of self-report and performance measures - highlighting significant complaints of subjective feeling of dizziness - were found in these patients when compared with healthy subjects. Multiple correlations were found between posturography testing and cervical range of motion and Dizziness Handicap Inventory as well as between different self-report and performance measures in cervicogenic dizziness patients.

CONCLUSIONS

The implementation of posturography - including power spectra analysis - coupled with appropriate exclusion of other disorders, may represent a useful tool in improving cervicogenic dizziness assessment in terms of cost, time consumption and correlation with other measurements.Implications for rehabilitationUncertainties in diagnostic assessment of cervicogenic dizziness reflect doubts regarding the causes underpinning the symptoms of imbalance, unsteadiness, and disorientation.Posturography measurement is a low-cost, time-sparing technique and its implementations have proven to be useful in detecting significant alterations in body sway during perturbating situations.Implementation of power spectra analysis on posturography testing may represent a useful tool in improving cervicogenic dizziness assessment also in terms of rehabilitative treatment follow-up.

The Effectiveness of Dry Needling and Exercise Therapy in Patients with Dizziness Caused By Cervical Myofascial Pain Syndrome; Prospective Randomized Clinical Study

Objective

The aim of this study is to compare the effectiveness of dry needling therapy combined with exercise and exercise treatment alone for alleviating the dizziness caused by cervical myofascial pain syndrome.

Design

This was a prospective randomized clinical study that included 61 women who had dizziness and myofascial trigger points on the neck muscles. The patients were randomized into a dry needling + exercise group (N = 31) and an exercise only group (N = 30).

Results

The mean age of the patients (±SD) was 38.4 ± 8.3 years. The intragroup comparisons of the severity of neck pain, algometric measurement, number of dizziness attacks per week, severity of the dizziness, fall index, and the Dizziness Handicap Inventory were improved in both groups at the first and fourth months (P < 0.05). The intergroup comparisons of the severity of neck pain, algometric measurement, number of dizziness attacks per week, the severity of the dizziness, and the Dizziness Handicap Inventory were more improved in the dry needling + exercise group at the first or fourth month compared with their inital assessments (P < 0.05). There was no diffence in fall index scores between the groups (P > 0.05).

Conclusions

Both dry needling + exercise therapy and exercise therapy alone were effective in treating dizziness caused by cervical myofascial pain syndrome. However, dry needling + exercise treatment was superior to exercise treatment alone.

Patient-reported outcomes measured with and without dizziness associated with non-specific chronic neck pain: implications for primary care

Background

The aim of this study was to compare health-related quality of life (HRQoL) and disability and fear of movement in patients with non-specific chronic neck pain (NSCNP) associated with dizziness with respect to patients with isolated NSCNP in primary care settings.

Methods

A cross-sectional study was carried out in a primary care center. A total of 120 patients were divided into two groups and analyzed in this study. One group of patients reported dizziness combined with NSCNP (n = 60), and the other reported no dizziness with their NSCNP (n = 60). Patient-reported outcome measurements were HRQoL (primary outcome) and disability and kinesiophobia (secondary outcomes) assessed by the EuroQoL Five Dimensions and Five Levels (EQ-5D-5L), neck disability index (NDI) and Tampa Scale of Kinesiophobia (TSK-11), respectively.

Results

Statistically significant differences (P < 0.05) for a 95% confidence interval (CI) with a large effect size (Cohen d) were found between both groups with greater values of disability (mean difference = 6.30 points; 95% CI [3.84-8.75]; d = 0.94) and kinesiophobia (mean difference = 8.36 points; 95% CI [6.07-10.65]; d = 1.33), and an impairment of HRQoL (mean difference = 16.16 points; 95% CI [11.09-21.23]; d = 1.16), for patients with NSCNP associated with dizziness with respect to patients with isolated NSCNP.

Conclusions

Patients with NSCNP in conjunction with dizziness present higher HRQoL impairment and higher disability and kinesiophobia compared to patients with isolated NSCNP.

The Role of Physical Therapy in Concussion Rehabilitation

A complex diagnosis such as concussion requires a multidisciplinary patient-centered approach to maximize health outcomes. There is growing evidence to support the role of the Physical Therapist as a key member of the team of healthcare professionals managing children and adolescents with a protracted recovery following concussion. Symptoms such as headache, dizziness, neck pain, gaze instability, balance dysfunction, and fatigue can be addressed through a multimodel approach. This article provides an overview of the targeted pathways of examination and treatment of individuals with a concussion through vestibular rehabilitation, cervicogenic rehabilitation, exertional training, and patient education.

Combined use of cervical headache snag and cervical snag half rotation techniques in the treatment of cervicogenic headache

[Purpose] Cervicogenic headache is a major problem in patients with upper cervical dysfunction. However, its physical therapy management is a topic of debate. This study aims to determine the effect of C1-C2 Mulligan sustained natural apophyseal glide mobilizations on cervicogenic headache and associated dizziness. [Participants and Methods] This study included 48 patients with cervicogenic headache, who were randomly assigned to three equal groups: Group A (Headache SNAG), group B (C1-C2 SNAG rotation), and group C (combined). Neck Disability Index was used to examine neck pain intensity and cervicogenic headache symptoms. The 6-item Headache Impact Test scale was used to examine headache severity and its adverse effects on social life and functions. Flexion-Rotation Test was used to assess rotation range of motion at the level of C1-C2 and confirmed by a cervical range of motion device. Dizziness Handicap Inventory scale was used to evaluate dizziness. The evaluation was done pre- and post-treatment and compared between the groups. [Results] Group C showed significant improvement in all variables compared with groups A and B. [Conclusion] Sustained natural apophyseal glide mobilizations used in the study were effective in reducing cervicogenic headache and dizziness in all groups with a greater improvement in the combined group. The use of cervical SNAG mobilizations is encouraged as a noninvasive intervention depending on the therapist's assessment, findings, and clinical reasoning.

Balance problems and dizziness after neck surgery - associations with pain and health-related quality of life

Introduction: Symptoms of dizziness or imbalance are often present in individuals with a variety of neck-disorders. The aims of this study were to determine the prevalence of patient-reported balance problems and dizziness 10-13 years after surgery for cervical degenerative disc disease; evaluate associations with neck pain and health-related quality of life; and investigate how these individuals described dizziness. Material and methods: Sixty-eight individuals, 10 years or more after anterior cervical decompression and fusion surgery, who previously participated in a randomized controlled trial were included. Participants completed questionnaires including ratings of dizziness and balance problems, the Dizziness Handicap Inventory, and an open-ended question regarding their experience of dizziness. Secondary outcomes were neck pain and quality of life. Results: Seventy-two percent experienced occasional or daily symptoms of unsteadiness and/or dizziness. Intensity ratings for dizziness during movement and for balance problems were similar and rather low, but had an impact on quality of life. Ratings of dizziness at rest were even lower. Dizziness ratings were associated with neck pain. Strenuous activities were related to dizziness and dizziness was primarily described as intermittent and non-rotatory. Conclusions: Dizziness or balance problems in the long-term after surgery for cervical degenerative disc disease are common and have an impact on daily life. Ratings of problem frequency and intensity were usually low. Dizziness and balance problems may affect quality of life. Patients' descriptions of these problems are in line with common symptoms of cervicogenic dizziness.
