Abstract
INTRODUCTION Inter-individual variability may contribute to impaired cervicocephalic kinesthetic sensibility (CKS) in patients with nonspecific neck pain. OBJECTIVES To identify subgroups of participants with nonspecific neck pain based on cervical joint position errors (JPEs) and to determine potential factors associated with identified subgroups. METHODS One hundred participants with nonspecific neck pain (unidentified pathoanatomical cause) and 50 controls were recruited. JPEs were measured in cervical extension and rotation, using a laser pointer. JPEs were expressed as absolute (AEs), constant (CEs), and variable (VEs) errors. Clinical characteristics were pain intensity, duration, disability, side of pain, dizziness, psychological features, and range of motion. All tests were performed within 1 day. A cluster analysis was conducted based on AEs. A logistic regression was used to identify factors associated with the cluster groups. RESULTS Analysis divided neck pain participants into two groups: cluster 1 with greater impaired CKS (n = 36) and cluster 2 with lesser impaired CKS (n = 64). The AEs (all cervical movements) and CE (left rotation) were larger in cluster 1 than 2 (p ≤ .002). Overall, participants in clusters 1 and 2 had larger AEs, CEs, and VEs than controls (p ≤ .04). The presence of dizziness was a risk factor associated with cluster 1 (OR=2.5, p = .04). The other characteristics were not associated with the cluster groups (p ≥ .09). CONCLUSION The AEs identified two subgroups of patients with nonspecific neck pain. Participants in subgroup 1 had greater impaired CKS, and participants in subgroup 2 had lesser impaired CKS. Dizziness was a potential risk factor associated with greater impaired CKS.

Abstract
The neck can be implicated in dizziness via several, separate, discreet mechanisms. Proprioceptive cervicogenic dizziness (CGD) is the most common and reflects the cervical spine's important role, along with visual and vestibular input, for sensorimotor control. Impaired cervical proprioception can lead to symptoms such as dizziness, unsteadiness, visual disturbances, and altered sensorimotor control, and treatment directed toward cervical musculoskeletal and sensorimotor control is efficacious to improve this in individuals with cervical musculoskeletal disorders. Despite this, CGD is difficult to diagnose. Many people present with both neck pain and dizziness, and often the onset of both follows head and neck trauma, but neither necessarily implicate the neck as the cause of dizziness. Further, people often present with mixed forms of dizziness. Thus, rather than diagnosing CGD, it might be more important to consider the potential for the neck to have no (nil, co-morbid cervical condition) or some (minor, major, or compensatory) role in dizziness. Determining the precise role of the cervical spine role in dizziness requires a skilled interview and examination for cervical musculoskeletal and related sensorimotor impairments and relevant testing of other potential causes. A combination and cluster of test outcomes in addition to comparing responses to specific tests when the cervical afferents are stimulated and not stimulated will be important. Considering the role of the neck in dizziness will allow a balanced approach in assessment and management to allow timely, effective intervention to be provided to the large number of individuals presenting with neck pain and dizziness (Supplemental Digital Content, available at: http://links.lww.com/JNPT/A484).

J Clin Med 2024; 13:4685. [PMID: 39200827 PMCID: PMC11355930 DOI: 10.3390/jcm13164685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/22/2024] [Accepted: 08/05/2024] [Indexed: 09/02/2024] Open
Abstract
Background: Myotonic dystrophy type 1 (DM1) is a rare multisystemic genetic disorder with motor hallmarks of myotonia, muscle weakness and wasting. DM1 patients have an increased risk of falling of multifactorial origin, and proprioceptive and vestibular deficits can contribute to this risk. Abnormalities of muscle spindles in DM1 have been known for years. This observational cross-sectional study was based on the hypothesis of impaired cervical proprioception caused by alterations in the neck spindles. Methods: Head position sense was measured in 16 DM1 patients and 16 age- and gender-matched controls. A head-to-target repositioning test was requested from blindfolded participants. Their head was passively rotated approximately 30° leftward or rightward and flexed or extended approximately 25°. Participants had to replicate the imposed positions. An optoelectronic system was adopted to measure the angular differences between the reproduced and the imposed positions (joint position error, JPE, °) concerning the intended (sagittal, horizontal) and unintended (including the frontal) planar projections. In DM1 patients, JPEs were correlated with clinical and balance measures. Static balance in DM1 patients was assessed through dynamic posturography. Results: The accuracy and precision of head repositioning in the intended sagittal and horizontal error components did not differ between DM1 and controls. On the contrary, DM1 patients showed unintended side-bending to the left and the right: the mean [95%CI] of frontal JPE was -1.29° [-1.99°, -0.60°] for left rotation and 0.98° [0.28°, 1.67°] for right rotation. The frontal JPE of controls did not differ significantly from 0° (left rotation: 0.17° [-0.53°, 0.87°]; right rotation: -0.22° [-0.91°, 0.48°]). Frontal JPE differed between left and right rotation trials (p < 0.001) only in DM1 patients. No correlation was found between JPEs and measures from dynamic posturography and clinical scales. Conclusions: Lateral head bending associated with head rotation may reflect a latent impairment of neck proprioception in DM1 patients.

Bexander CSM, Hodges PW. Neck muscle activation in response to eye movement depends on sitting posture and is modified in whiplash associated disorders: Cross-sectional study. Musculoskelet Sci Pract 2023; 67:102837. [PMID: 37598498 DOI: 10.1016/j.msksp.2023.102837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 07/24/2023] [Accepted: 08/01/2023] [Indexed: 08/22/2023]
Abstract
BACKGROUND Activity of specific neck muscles is modulated by eye movement. This activity modulation is exaggerated in people with whiplash associated disorders (WAD), but it is unknown whether it is impacted by sitting posture. OBJECTIVE This study investigated; (i) whether activity of cervical muscles differs with spinal posture; (ii) whether the effect of eye gaze direction (horizontal/vertical) on neck muscle activity differs between postures, and (iii) whether these effects differ between individuals with and without WAD. METHODS In three seated postures (normal relaxed, head forward, sit tall) electromyography (EMG) was recorded right obliquus capitis inferior (OI), multifidus (MF), splenius capitis (SP) and left sternocleidomastoid (SCM) with fine-wire and surface electrodes in ten healthy controls and nine with WAD. Electro-oculography recorded eye movements. RESULTS In controls, EMG was less for extensor muscles in Sit Tall than Head Forward, but higher in SCM. Only SC EMG modulated with eye movement. When WAD participants adopted similar sitting postures several responses were different; compared to Normal Relaxed posture OI EMG was less in Head Forward; MF EMG was less in Sit Tall; and SC was less in Head Forward and Sit Tall. Neck muscles in WAD were generally more sensitive to eye movement, except SC which did not modulate. CONCLUSIONS These finding support the hypothesis that neck muscle activity is influenced by spinal posture and eye movement. In WAD, this relationship is distorted and the response to eye movement is increased. SIGNIFICANCE These observations have potential implications for clinical management of individuals with WAD.

Abstract
BACKGROUND Migraine patients may present with both cervical and balance dysfunctions. The neck plays an important role in balance by providing substantial proprioceptive input, which is integrated in the central nervous system and influences the balance control systems. Whether balance and neck dysfunctions are associated in patients with migraine is still to be explored. OBJECTIVES This study aimed to assess the association between the sensory organization test of balance with neck pain features, cervical strength, endurance, and range of motion in patients with migraine. METHODS Sixty-five patients with migraine underwent the sensory organization test assessed with the Equitest-Neurocom® device. Maximum voluntary isometric contraction, cervical flexion and extension range of motion, and cervical flexor and extensor endurance were assessed. In addition, the features of migraine and neck pain were collected. Patients were dichotomized according to cut-off scores of balance performance and the association between outcomes were explored. RESULTS Patients with reduced balance performance presented a higher frequency of migraine (p = 0.035), a higher frequency of aura (p = 0.002), greater neck pain intensity (p = 0.013), and decreased endurance of cervical flexors (p = 0.010) and extensors (p < 0.0001). The total balance score was correlated with age (r = -0.33; p = 0.007), migraine frequency (r = -0.29; p = 0.021), neck pain intensity (r = -0.26; p = 0.038), and endurance of the cervical flexors (r = 0.39; p = 0.001) and extensors (r = 0.36; p = 0.001). Migraine frequency, neck pain intensity, and endurance of the cervical flexors can predict 21% of the sensory organization test variability. CONCLUSION Neck pain features and endurance of the cervical muscles are related to reduced balance performance in patients with migraine. These results shed light to a better understanding of balance alterations in migraine patients.

Abstract
PURPOSE Age-related decreases in cervical mobility and proprioception have previously been demonstrated. Potential associations of these deteriorations with fall risk have not been investigated so far. This study aims to compare cervical mobility and proprioception between fallers and non-fallers and prospectively assess the contribution of these parameters in fall risk identification among healthy older adults. METHODS 95 community-dwelling older adults underwent a cervical screening. Active cervical range of motion (aCROM) was measured using a digital inclinometer and cervical proprioception was assessed by determining joint position error (JPE). Fear of falling was identified through the Iconographical Falls Efficacy Scale (iconFES). Falls were prospectively recorded during a 1-year follow-up period using monthly calendars. Univariate and multivariate logistic regression analyses were conducted to examine the association between these parameters and falls occurrence. RESULTS Baseline measurements revealed reduced cervical performance (i.e., smaller aCROM and larger JPE) among individuals who reported at least one fall during the following year ("fallers"). The multivariate logistic regression model contained eight independent variables (age, sex, walking aid, fall history, iconFES, aCROM F, aCROM E and JPE) and correctly classified 77.8% of cases. CONCLUSION Although the contribution of cervical parameters to fall risk identification seems to be rather small compared to well-known (though often unmodifiable) major risk factors, further research is needed to elucidate underlying mechanisms of cervical functions in relation to falls. Second, it would be interesting to develop a targeted fall preventive cervical exercise program and assess its effectiveness in terms of falls occurrence.

Abstract
Background Blepharospasm is a focal dystonia that presents as involuntary, intermittent, continuous contractions of the eyelids. Abnormal eyelid contractions in blepharospasm are expected to cause balance problems, but there is no clear information. Objective This study was designed to evaluate the effect of blepharospasm on postural stability (PS) in patients with blepharospasm. As a secondary endpoint, the efficacy of botulinum toxin type-A (BoNT-A) treatment on static balance in patients with blepharospasm was investigated. Methods Twenty-four patients with blepharospasm receiving regular BoNT-A injections and 20 age-matched and sex-matched healthy controls were included in the study. All subjects were evaluated on a static posturography force platform performing four tasks (eyes open (EO), eyes closed (EC), tandem Romberg (TR) and verbal cognitive task (COGT)). Evaluations of the patients were repeated 4 weeks after the injection. Results Pretreatment lateral and anterior-posterior sways, sway area and velocities of the sways were significantly higher in patients than controls during the COGT and TR (p<0.05). In the patient group, with EO and EC, a few parameters improved after BoNT-A injection. On the other hand, in the TR and COGT, most of the sway parameters and velocities improved significantly after treatment (p<0.05). Conclusions Blepharospasm may cause functional blindness in patients. This study demonstrated that PS worsens in patients with blepharospasm under dual-task conditions. BoNT-A injection treats the disease itself and, thus, markedly improves PS under dual-task conditions in blepharospasm.

Abstract
Purpose: Neck pain is associated with gait disturbances. The first aim of this study was to examine spatiotemporal gait parameters, pelvic movements and pelvic symmetry during single and dual task conditions in persons with CINP compared to healthy subjects (HS). The second aim was to investigate the relationship between disability and gait in persons with CINP.Methods: Thirty-one individuals with CINP (mean age 22.06±1.38 years, range 18-56 years) and 24 HS (mean age 22.60±1.51 years, range 18-43 years) participated in the study. CINP group completed Neck Disability Index. All participants performed 10-meter walking test in two conditions: (1) walking with head straight at usual speed, (2) walking with head straight at usual speed while carrying a tray. The BTS G-Walk wearable sensor was used to assess spatiotemporal parameters (speed, cadence, step length), pelvic movements (tilt, obliquity, rotation), and pelvic symmetry. Results: During single task gait, the CINP group had significantly lower walking speed, shorter stride length and worse pelvic tilt symmetry (p<0.05), but pelvic movements did not differ significantly according to the HS (p<0.05). During dual task condition, the CINP group had significantly lower cadence, gait speed and stride length, significantly increased pelvic movements and significantly worse pelvic rotation symmetry compared to HS (p<0.05). Conclusion: Patients with CINP had a slower gait, lower stride length, decreased pelvic symmetry and increased pelvic movements compared to HS. Differences in gait and pelvic movements between the two groups were more pronounced during the dual task gait than single task gait.

Abstract
OBJECTIVE To determine reference values, including the appropriate number of repetitions, and test-retest reliability of the torsion and conventional cervical joint position sense (JPS) tests. METHODS Phase 1) Cross-sectional design to determine reference values and the appropriate number of repetitions; Phase 2) repeated-measures concordance design (test-retest reliability). Sixty-eight healthy participants performed 10 repetitions of randomized rotation left and right for both cervical JPS tests using a laser projected onto a target. Thirty participants returned for the same evaluation process one week later. RESULTS The age-stratified reference values for the torsion JPS test showed greater absolute error as age increased. Stable levels of performance were obtained with 6-7 repetitions for both tests. Moderate to good reliability was found with 7 or more repetitions for left rotation [Torsion JPS test, Intraclass Correlation Coefficient (ICC; 95% CI) = 0.85 (0.68-0.93); Conventional JPS test, ICC = 0.78 (0.53-0.89)], and 6-7 or more repetitions for right rotation [Torsion JPS test, 6 repetitions, ICC = 0.79 (0.56-0.90); Conventional JPS test, 7 repetitions, ICC = 0.82 (0.61-0.91)]. Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) stabilized at 7 repetitions in both tests [Torsion JPS test (SEM ≤ 1.0°; MDC90 ≤ 2.4°; MDC95 ≤ 2.9°); Conventional JPS test (SEM ≤ 1.2°; MDC90 ≤ 2.8°; MDC95 ≤ 3.3°)]. CONCLUSIONS The reference values generated for the torsion JPS test may help identify the presence of impairments cervical proprioception. At least 7 repetitions optimize stability, reliability and responsiveness in the torsion and conventional cervical JPS tests.

Abstract
BACKGROUND Longus colli muscle has a significant role in postural control. A reduction of longus colli cross-sectional area (CSA) has been demonstrated in neck pain patients. However, pain-side related difference and its relationship with clinical features and standing balance remain unclear. OBJECTIVE To investigate side-to-side difference in the longus colli CSA and to determine the relationships of the CSA with clinical characteristics and standing balance in neck pain patients. STUDY DESIGN Cross-sectional study. MATERIALS AND METHODS Fifty participants with chronic non-specific neck pain (20 unilateral and 30 bilateral) were recruited. CSA of the longus colli muscle was measured using ultrasound imaging. Balance was measured using a force platform during a narrow stance with eyes open, eyes closed, and neck torsion (left and right). Balance outcomes were sway area and displacement in anterior-posterior (AP) and medial-lateral (ML) directions. Clinical characteristics were neck pain intensity, disability, and duration. RESULTS The longus colli CSA was reduced on the painful side in patients with unilateral neck pain (p < 0.01). There was a trend towards reduced CSA on the more painful side in those with bilateral neck pain (p = 0.08). The reduced CSA was mostly correlated with the greater AP sway displacement and sway area (r ranged from -0.27 to -0.54, p < 0.05). The longus colli CSA was not correlated with pain intensity, disability, and duration (p > 0.05). CONCLUSION The longus colli CSA was reduced on the painful side of neck pain. The reduced CSA was correlated with impaired standing balance, but not with clinical characteristics of neck pain.

Abstract
BACKGROUND While morphological changes to the cervical spine have been observed for over 40 years in response to contact sport participation, little is known about the secondary effects of the cervical impairment on future musculoskeletal injury and disability. OBJECTIVES AND DESIGN A scoping review was performed to discuss the relationship between contact sport participation and morphological changes to the cervical spine. Moreover, the correlation between morphological changes in the musculoskeletal structures of the cervical spine and resultant deficits in cervical sensorimotor and neuromotor function are discussed. Lastly, how alterations in cervical sensorimotor function may affect overall risk of musculoskeletal injury is discussed. METHODS The scientific literature was searched in PubMed, Sport Discus, and Web of Science pertaining to contact-sport athletes and/or cervical pathology and the cervicocephalic network. The Asksey and O'Malley's framework and PRISMA for Scoping Reviews were used to conduct and report the following review. Included articles were grouped into three categories: (1) Morphological changes to the cervical spine in contact sport athletes. (2) The role of the neuromotor pathways of the cervical spine in maintenance of postural tone and coordination of the extremities. (3) The correlation between altered cervical sensorimotor function and a resultant increase in musculoskeletal injury risk. RESULTS Our search identified 566 documents, of which 405 underwent full-text screening, resulting in 54 eligible studies for the review. Widespread cervical sensorimotor dysfunction was observed in contact sport athletes. Independently, cervical sensorimotor function was demonstrated to play a critical role in postural control and limb coordination. However, limited research exists exploring the interaction between contact sport participation and altered cervical sensorimotor function, as well as an associated increase in musculoskeletal injury risk. CONCLUSIONS Limited evidence exists linking cervical injury and/or observed deficits in cervical sensorimotor and neuromotor function to musculoskeletal injury risk. Longitudinal studies combining imaging measures (e.g., MRI, DEXA), cervical functional test, and prospective injury risk are needed to further explore the correlation between resultant cervical sensorimotor deficits following contact sport impacts and future musculoskeletal injury risk.

Immediate effect of lower extremity joint manipulation on a lower extremity somatosensory illusion: a randomized, controlled crossover clinical pilot study. Front Hum Neurosci 2022; 16:1011997. [DOI: 10.3389/fnhum.2022.1011997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 10/17/2022] [Indexed: 11/11/2022] Open
Abstract
Objective: This study explored the influence of lower extremity manipulation on the postural after-effects of standing on an inclined surface.Methods: Eight healthy individuals (28.0 ± 4.1 years) were recruited for this open-label, crossover study. Participants stood on an incline board for 3 min to develop a known form of somatosensory illusion. After randomization to either a lower-extremity joint manipulation or no intervention, participants immediately stood on a force plate for 3 min with eyes closed. After a 24-h washout period, participants completed the remaining condition. Center of pressure (CoP) position data was measured by a force plate and evaluated using statistical parametric mapping. Pathlength, mean velocity, and RMS were calculated for significant time periods and compared with corrected paired t-tests.Results: Parametric maps revealed that CoP position of control and intervention conditions differed significantly for two time periods (70–86 s—control: 0.17 ± 1.86 cm/intervention: −1.36 ± 1.54 cm; 141–177 s—control: −0.35 ± 1.61 cm/intervention: −1.93 ± 1.48 cm). CoP pathlength was also significantly decreased for the second period (control: 6.11 ± 4.81 cm/intervention: 3.62 ± 1.92 cm).Conclusion: These findings suggest that extremity manipulation may be a useful intervention for populations where CoP stability is an issue. This study contributes to the growing body of evidence that manipulation of the extremities can drive global postural changes, as well as influence standing behavior. Further, it suggests these global changes may be driven by alterations in central integration.Clinical Trial Registration:ClinicalTrials.gov, NCT Number: NCT05226715.

The University of Kansas Health System Outpatient Clinical Concussion Comprehensive Protocol: An Interdisciplinary Approach. Health Serv Insights 2022; 15:11786329221114759. [PMID: 36034733 PMCID: PMC9411741 DOI: 10.1177/11786329221114759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Accepted: 06/30/2022] [Indexed: 11/24/2022] Open
Abstract
Objective: The concussion team at The University of Kansas Health System outpatient rehabilitation spine center is comprised of experienced multi-disciplinary experts including physical therapists and a speech language pathologist. The team set forth with a purpose of creating and organizing an internal physical therapy clinical recommendation protocol for initial evaluations and subsequent treatments for the concussed patient. The aim of this paper is to share these recommendation protocols with other therapy teams and provide a foundational layout for treating the patient with post-concussion symptoms in an outpatient physical therapy clinical setting. Study design: Clinical recommendation protocol provides guidance for patients ages 10+ from initial evaluation through discharge with emphasis on evidence-based research in the areas of: oculomotor, cervical, vestibular, post-concussion migraine influence, mood disorders(such as anxiety and depression), exertion, and cognitive communicative dysfunction. Results: Finding a written, comprehensive clinical resource protocol for post-concussion outpatient evaluation(s) and treatment strategies can be difficult. This document serves as a resource for other outpatient concussion rehabilitation clinics, providing rationale, and objective measurement tools, for assessing and treating concussion patients. To the authors’ knowledge, no other research has produced a practical, efficient evaluation tool to be utilized at bed side, condensing evidence-based research into an easy-to-use form. Conclusion: The University of Kansas Health System outpatient concussion rehabilitation center developed clinical recommendation protocols for concussion care. The intent was to standardize assessment and treatment for concussion patients and to share these objective measurement tools and procedures, focused on a team approach of concussion providers, as a clinical outline for both the novice and seasoned clinician specializing in the field of concussion work in an outpatient rehabilitation setting.

Relationship between Cervicocephalic Kinesthetic Sensibility Measured during Dynamic Unpredictable Head Movements and Eye Movement Control or Postural Balance in Neck Pain Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148405. [PMID: 35886255 PMCID: PMC9317579 DOI: 10.3390/ijerph19148405] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 07/05/2022] [Accepted: 07/07/2022] [Indexed: 01/27/2023]
Abstract
Cervical afferent input is believed to affect postural balance and oculomotor control in neck pain patients, but its relationship to cervicocephalic kinesthesia, describing movement sense, has not yet been studied. The aim of this study was to analyze the relationship of two aspects of cervicocephalic kinesthesia to postural balance and oculomotor control in neck torsion positions. Forty-three idiopathic neck pain patients referred from orthopedic outpatient clinics and forty-two asymptomatic controls were enrolled in the study. A force plate was used to measure center-of-pressure movements during parallel stances under neutral and neck torsion maneuvers. Video-oculography was used to assess eye movements during smooth pursuit neck torsion test (SPNTT), while kinesthetic awareness was measured using the Butterfly test and head-to-neutral relocation test. Multiple regression was used to describe relationships between tests. Body sway in the anterior-posterior direction was related to Butterfly parameters but less to the head-to-neutral test. A medium relationship between Butterfly parameters and gain during SPNTT, with less SPNT-difference, was observed, but not for the head-to-neutral test. It can be concluded that specific aspect of neck kinesthetic functions (i.e., movement sense) importantly contributes towards oculomotor and balance control, which is more evident under neck torsion positions in neck pain patients, but is less pronounced in asymptomatic individuals.

Abstract
OBJECTIVE The purpose of this systematic review was to determine the reliability and, where possible, the validity of cervicocephalic proprioceptive (CCP) tests in healthy adults and clinical populations. METHODS A systematic search, utilizing 7 databases from the earliest possible date to April 14, 2021, identified studies that measured reliability of CCP tests. Studies were screened for eligibility, and included studies were appraised using Quality Appraisal Tool for Studies of Diagnostic Reliability (QAREL) and Quality Assessment and Diagnostic Accuracy Studies-2 Tool (QUADAS-2) tools. Validity outcomes were assessed for included studies. RESULTS Of 34 included studies, 29 investigated reliability for sense of position tests, 10 involved sense of movement tests, and 1 used a sense of force test. The head to neutral test was reliable and valid when 6 or more repetitions were performed within the test, discriminating between those with and without neck pain. Head tracking tests were reliable with 6 repetitions, and 1 study found discriminative validity in a whiplash population. Studies that found discriminative validity in sense of position reported mean joint position error generally >4.5° in the neck pain group and <4.5° in the asymptomatic group. No sense of force test was applied to a clinical population. Convergent validity analysis showed that these proprioceptive tests have low correlations with each other. CONCLUSION The reliability and validity of CCP tests for sense of position and movement are dependent upon equipment and repetitions. Six repetitions are generally required for good reliability, and joint position error >4.5° is likely to indicate impairment in sense of position.

Abstract
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.

Abstract
Traumatic brain injury (TBI) refers to the alteration of typical brain function that occurs following a blow to the head. Even a mild case of traumatic brain injury (mTBI) can lead to long-term impairment, so accurate and timely detection is vital. Visual symptoms are common following mTBI, so while it may seem to fall outside their typical scope of practice, optometrists are ideally qualified to assess the visual impacts and help with the diagnosis of mTBI. Given that mTBI is challenging to objectively diagnose and has no universally accepted diagnostic criteria, clinicians can lack confidence in diagnosing mTBI, and be hesitant in becoming involved in the management of such patients. The development of easily quantifiable techniques using eye tracking as an objective diagnostic tool provides practitioners with an easier pathway into the field, assigning numerical values to parameters which are difficult to assess using conventional optometric tests. As this evolving technology becomes increasingly integrated into optometric clinical settings, the potential for it to identify deficits accurately and reliably in patients following mTBI, and to monitor both their recovery and the effectiveness of potential treatments will increase. This paper provides an overview of clinical tests, relevant to optometrists, that can uncover oculomotor, attentional, and exteroceptive deficits following a mTBI, so that an optometrist with an interest in eye tracking can play a role in the detection and monitoring of mTBI symptoms.

Braz J Phys Ther 2021; 25:826-836.

Abstract
BACKGROUND Impairments of sensorimotor control relating to head and eye movement control and postural stability are often present in people with neck pain. The upper cervical spine and particularly the obliquus capitis inferior (OCI) play an important proprioceptive role; and its impairment may alter cervical sensorimotor control. Dry needling (DN) is a valid technique to target the OCI. OBJECTIVES To investigate if a single DN session of the OCI muscle improves head and eye movement control-related outcomes, postural stability, and cervical mobility in people with neck pain. METHODS Forty people with neck pain were randomly assigned to receive a single session of DN or sham needling of the OCI. Cervical joint position error (JPE), cervical movement sense, standing balance and oculomotor control were examined at baseline, immediately post-intervention, and at one-week follow-up. Active cervical rotation range of motion and the flexion rotation test were used to examine the global and upper cervical rotation mobility, respectively. RESULTS Linear mixed-models revealed that the DN group showed a decrease of JPE immediately post-intervention compared to the sham group (mean difference [MD]= -0.93°; 95% confidence interval [CI]: -1.85, -0.02) which was maintained at one-week follow-up (MD= -1.64°; 95%CI: -2.85, -0.43). No effects on standing balance or cervical movement sense were observed in both groups. Upper cervical mobility showed an increase immediately after DN compared to the sham group (MD= 5.14°; 95%CI: 0.77, 9.75) which remained stable at one-week follow-up (MD= 6.98°; 95%CI: 1.31, 12.40). Both group showed an immediate increase in global cervical mobility (MD= -0.14°; 95%CI: -5.29, 4.89). CONCLUSION The results from the current study suggest that a single session of DN of the OCI reduces JPE deficits and increases upper cervical mobility in patients with neck pain. Future trials should examine if the addition of this technique to sensorimotor control training add further benefits in the management of neck pain.

Abstract
The proprioceptive sense is a very important function for the body, and joint position error test (JPET) is commonly used to measure it. This study was to analyze the difference of proprioception in standing and sitting postures through the JPET. A total of 60 students (M/F, 12/48) in D University in Gyeongsangbuk-do, South Korea participated in this study. A JPET was performed with the subject’s eyes closed to assess the neck proprioception. The movement of the neck was measured in flexion, extension, and lateral flexion, and separately measured when sitting and standing. The difference in repositioning errors between sitting and standing postures was analyzed using paired [Formula: see text]-test. There was a significant difference in repositioning errors between sitting and standing posture in neck extension. There was no significant difference in repositioning errors between sitting and standing posture in neck flexion and lateral flexion. In conclusion, in a sitting posture, posterior neck muscles are used more than in the standing posture, which may negatively affect the proprioceptive accuracy of the neck and may also increase the neck repositioning errors.

Abstract
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.

Abstract
To investigate the effects of increasing axial load on cervical motor control. Surrogates of cervical motor control were active cervical range of motion (C-ROM) and joint position error (JPE) assessed in flexion, extension, lateroflexion and rotation directions in 49 healthy young men (mean age: 20.2 years). All measurements were executed with 0-, 1-, 2-, and 3-kg axial loads. Linear mixed models were used to assess the effects of axial loading and cervical movement-direction on C-ROM and JPE. Post-hoc analysis was performed to compare load levels. Axial loading (p = 0.045) and movement direction (p < 0.001) showed significant main effects on C-ROM as well as an interaction (p < 0.001). C-ROM significantly changed with 3-kg axial load by decreaseing extension (− 13.6%) and increasing lateroflexion (+ 9.9%). No significant main effect was observed of axial loading on JPE (p = 0.139). Cervical motor control is influenced by axial loading, which results in decreased C-ROM in extension and increased C-ROM lateroflexion direction.

Abstract
BACKGROUND Performing thoracic manipulations for neck pain can result in immediate improvements in neck function. OBJECTIVE The aim of this study was to investigate the immediate effects of thoracic manipulation on cervical joint position sense and cervical range of motion in individuals with chronic mechanical neck pain. METHODS Eighty male volunteers between 18-25 years and having chronic or recurrent neck or shoulder pain of at least 3 months duration with or without arm pain were randomized into two groups: Thoracic Manipulation Group (TMG:50) and Control Group (CG:30), with a pretest-posttest experimental design. The TMG was treated with thoracic extension manipulation while the CG received no intervention. Cervical joint position error and cervical range of motion of the individuals were assessed at baseline and 5 minutes later. RESULTS There was no difference in demographic variables such as age (p= 0.764), Body Mass Index (p= 0.917) and Neck Pain Disability Scale (NPDS) scores (p= 0.436) at baseline outcomes between TMG and CGs. Joint position error outcomes between the two groups following intervention were similar in all directions at 30 and 50 degrees. Differences in range of motion following intervention in neck flexion (p< 0.001) and right rotation (p= 0.004) were higher in TMG compared to CG. CONCLUSIONS A single session of thoracic manipulation seems to be inefficient on joint position sense in individuals with mild mechanical neck pain. However, thoracic manipulation might be an effective option to increase flexion and rotation of the cervical region as an adjunctive to treatment.

Abstract
INTRODUCTION Mechanical neck pain (MNP) is a commonly occurring musculoskeletal condition that is usually managed using electrical modalities, joint mobilization techniques, and therapeutic exercises, but has limited evidence of their efficacy. Pathology (densification) of the deep cervical fascia that occurs due to the increased viscosity of hyaluronic acid (HA) may induce neck pain and associated painful symptoms of the upper quarter region. Fascial manipulation (FM) and yoga poses are considered to reduce the thixotropy of the ground substances of the deep fascia and improve muscle function. The purpose of this study is to investigate the effect of FM and sequential yoga poses (SYP) when compared to the usual care on pain, function, and oculomotor control in MNP. METHODS This FaCe-Man trial will recruit 160 patients with subacute and chronic mechanical neck pain diagnosed using predefined criteria. Participants will be randomized to either the intervention group or the usual care group, using a random allocation ratio of 1:1. Patients in the intervention group will receive FM (4 sessions in 4 weeks) and SYP (12 weeks) whereas the standard care group will receive cervical mobilization/ thoracic manipulation (4 sessions in 4 weeks) and therapeutic exercises (12 weeks). The primary outcome is the change in the numeric pain rating scale (NPRS). The secondary outcomes include changes in the patient-specific functional scale and oculomotor control, myofascial stiffness, fear-avoidance behavior questionnaire, and elbow extension range of motion during neurodynamics test 1. DISCUSSION If found effective, FM along with SYP investigated in this trial can be considered as a treatment strategy in the management of mechanical neck pain. Considering the magnitude of the problem, and the pragmatic and patient-centered approach to be followed, it is worth investigating this trial.

Brain Sci 2021; 11:brainsci11081047. [PMID: 34439666 PMCID: PMC8394036 DOI: 10.3390/brainsci11081047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 07/24/2021] [Accepted: 08/04/2021] [Indexed: 11/16/2022] Open
Abstract
Attention Deficit Hyperactivity Disorder (ADHD) is a prevalent, chronic neurodevelopmental disorder that affects oculomotor (eye movement) control. Dysfunctional oculomotor control may result in reading or educational difficulties. This randomized controlled crossover study sought to investigate the feasibility of a larger scale trial and effects of a single session of spinal manipulation on oculomotor control in children with ADHD. Thirty children participated in the study and were randomized into either control-first or spinal manipulation first groups. The results indicate that the trial was feasible. Secondary outcomes showed that there was a significant decrease in reading time after the spinal manipulation intervention compared to the control intervention. Future studies of the effects of spinal manipulation on oculomotor control in children with ADHD are suggested.

A meta-analysis and systematic review of changes in joint position sense and static standing balance in patients with whiplash-associated disorder. PLoS One 2021; 16:e0249659. [PMID: 33831060 PMCID: PMC8031393 DOI: 10.1371/journal.pone.0249659] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 03/23/2021] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVE To synthesise and analyse the current evidence regarding changes in joint position sense (JPS) and standing balance in people with whiplash-associated disorder (WAD) taking the presence or absence of dizziness into account. DATA SOURCES PubMed, CINAHL Plus, Web of Science, Embase, MEDLINE and APA PsycINFO were searched by two independent reviewers from inception until August 2020 and reference lists of all included studies were also reviewed. STUDY SELECTION Only cross-sectional studies that measured JPS and/or standing balance between people with WAD vs. healthy controls (HC) or people with WAD complaining of dizziness (WADD) vs. those not complaining of dizziness (WADND) were selected. DATA EXTRACTION Relevant data were extracted using specific checklists and quality assessment was performed using Downs and Black Scale (modified version). DATA SYNTHESIS Twenty-six studies were included. For JPS, data were synthesized for absolute error in the primary plane of movement for separate movement directions. For standing balance, data were synthesized for traditional time- and frequency domain sway parameters considering the conditions of eyes open (EO) and eyes closed (EC) separately. For meta-analysis, reduced JPS was observed in people with WAD compared to HC when the head was repositioned to a neutral head position (NHP) from rotation (standardised mean difference [SMD] = 0.43 [95%: 0.24-0.62]) and extension (0.33 [95%CI: 0.08-0.58]) or when the head was moved toward 50° rotation from a NHP (0.50 [0.05-0.96]). Similarly, people with WADD had reduced JPS compared to people with WADND when the head was repositioned to a NHP from rotation (0.52 [0.22-0.82]). Larger sway velocity and amplitude was found in people with WAD compared to HC for both EO (0.62 [0.37-0.88] and 0.78 [0.56-0.99], respectively) and EC (0.69 [0.46-0.91] and 0.80 [0.58-1.02]) conditions. CONCLUSION The observed changes of JPS and standing balance confirms deficits in sensorimotor control in people with WAD and especially in those with dizziness.

Abstract
INTRODUCTION Mild traumatic brain injury (mTBI) and whiplash are two pathologies which appear in the follow-up of a cranio-cervical trauma. The objective of this study is to review their definitions, to discuss each entity. METHODS Whiplash and mTBI were defined. Then, a systematic literature review was carried out using the Pubmed database. Relevant studies after 1995 were selected, with 16 articles describing a link between whiplash and mTBI. 8 articles were analyzed after reading their abstracts. RESULTS Whiplash and mTBI have many similarities (symptoms, biomechanics, cognitive disorders, presence of diffuse axonal lesions on functional imaging) and some differences (in posture, more vestibular and balance disorders in whiplash). mTBIs result from linear accelerations between 60- 160g (gravity), studies on whiplash have shown that they can appear from 4.5g, which could explain biomechanically the frequent concomitant appearance. Cervical joint dysfunction can appear in persistent concussive syndrome, with upper cervical pain, less endurance of the cervical flexor muscles, and an increase in cervical stiffness leading to tension headache. This could explain neck pain in mTBI and headache in whiplash. An explanation to vestibular and cochlear disorders is given, and the two pathologies concomitantly could increase the symptoms. CONCLUSION To our knowledge, no studies define distinct boundaries between these two pathologies, which overlap on many points. An explanation is their concomitant onset, due to the biomechanics of the trauma and anatomical reasons. Larger-scale studies of rigorous scientific quality are needed to answer the question of the difference between whiplash and mTBI.

Abstract
BACKGROUND Cervical dystonia (CD) is the most common form of focal dystonia. It is not known exactly whether abnormal head postures in cervical dystonia cause balance problems. Dual-tasking is a common every-day life situation. OBJECTIVE We aimed to evaluate postural stability (PS) in patients with CD and the effect of cognitive task on PS. As a secondary aim, we evaluated the effect of onabotulinum toxin A (BoNT) injection on PS. METHODS A total of 24 patients with CD who were on BoNT treatment for at least one year and 23 healthy controls were included. Posturographic analyses were carried out in all the subjects on static posturography platform under four different conditions: eyes open, eyes closed, tandem stance and cognitive task. In patients, posturographic analysis was carried out just before the BoNT injections and was repeated four weeks later. RESULTS Before treatment, the anterior-posterior sway was significantly higher in CD patients with the eyes open condition compared to the controls (p=0.03). Cognitive task significantly affected several sway velocities. Tandem stance significantly affected many sway parameters, whereas the eyes closed condition did not. After treatment, only two parameters in tandem stance and one in cognitive task improved within the patient group, in a pairwise comparison. CONCLUSIONS Postural control is impaired in CD patients probably due to the impaired proprioceptive and sensorimotor integration. In reference to dual task theories possibly due to divided attention and task prioritization, cognitive dual-task and harder postural task disturbes the PS in these patients.

Abstract
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.

Motor vehicle crash reconstruction: Does it relate to the heterogeneity of whiplash recovery? PLoS One 2019; 14:e0225686.

Abstract
Whiplash injury is a common consequence of motor vehicle crashes (MVC), yet it is also one of the most poorly understood. While more than 50% of those injured should expect to rapidly recover, others are not as fortunate with approximately 25% of those exposed to and injured in an MVC transitioning from acute to chronic pain and disability. The purpose of this prospective study was to determine if the severity and direction of collisions involving participants enrolled in a longitudinal study of recovery from whiplash are able to differentiate between different recovery groups based on the neck disability index (NDI) percentage scores at 3-months, and if these crash specific parameters are associated with known risk factors for recovery. Here, we examined objective collision data, repair invoices, and characteristics of the crash for 37 acutely injured participants consented and enrolled at their emergency department visit and further assessed at three time points; < 1 week, 2-weeks, and 3-months post MVC. Collision data were used to reconstruct and estimate the severity of the crash and determine if they aligned with the heterogeneity of whiplash injury recovery. Wilcoxon rank sum tests were used to determine if % scores on the Neck Disability Index (NDI) at 3-months post MVC were associated with the following variables: sex, head turned at time of impact, seatbelt use, whether or not airbags deployed, if the vehicle was struck while stopped or while turning, or the principle direction of force (PDOF). Spearman’s correlation coefficients were used to determine if NDI at 3-months post MVC was associated with age, Body Mass Index, pain-related disability at baseline, signs of post-traumatic distress, intrusion/hyperarousal, negative affect, pain intensity, estimated speed change from the impact, and damage estimates (in US$). There was a significant positive association between self-reported neck disability at 3-months post MVC, post-traumatic distress, negative affect and uncontrolled pain. There was no direct effect of participant characteristics, arousal, intrusion/hyperarousal sub-score, damage, PDOF, speed change, or other crash characteristics. Established crash parameters were not associated with the heterogeneity of whiplash injury recovery in a small sample of injured participants.

Abstract
BACKGROUND There are different neck proprioceptive tests that are believed to be targeting different sources of proprioceptive information. OBJECTIVE To assess the reliability, measurement error, discriminative validity and convergent validity of four proprioceptive tests (head repositioning to neutral - HRNT, torsion test - TT, head repositioning to 30° rotation - HR30T and figure of eight relocation test - F8T) in individuals with chronic idiopathic neck pain and asymptomatic individuals. A secondary aim was to assess the divergent validity of these tests by correlating them against measures of disability, pain catastrophizing and fear of movement. DESIGN - Reliability and validity study. METHODS - 66 participants (33 with chronic neck pain and 33 asymptomatic) were assessed using four proprioceptive tests, pain catastrophizing scale, neck disability index, tampa scale of kinesiophobia and visual analogue scale. RESULTS Proprioceptive tests showed moderate to good reliability (ICC: 0.55 to 0.85), but high measurement error. All tests but the HR30T were significantly different between participants with and without neck pain (p < 0.05). Only the HRNT showed an area under the curve above 0.5 (AUC95% CI = 0.51; 0.78, p ≤ 0.042). Between test correlations ranged between 0.35 and 0.61 and correlations between proprioceptive tests and catastrophizing, fear of movement and disability were, in general, lower than 0.3. CONCLUSION The four proprioceptive tests showed reliability and measurement errors good enough for group comparisons but of limited utility for individual comparisons. They seem to measure related but dissimilar constructs and the HRNT seemed better at discriminating individuals with and without NP and easier to perform in clinical practice.

Abstract
Rheumatoid arthritis (RA) involving the cervical spine can lead to various neurologic defects and impairment of proprioception is just one of them. The aim of this study was the assessment of cervical proprioception and its relation with radiographic, clinical, and functional characteristics of patients with RA. One hundred and six rheumatoid arthritis patients who diagnosed according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria and age, gender, educational status matched one hundred and six healthy volunteers were enrolled in this study. Cervical joint position error test (CJPET) was applied to healthy volunteers and RA patients for cervical proprioception assessment. Fatigue, depression, balance, quality of life and balance scales were administered to all patients. Cervical radiography was used to assess cervical subluxations. Regression analysis was used for grading the factors which had relations with cervical proprioception. Mean age of patients and healthy volunteers was 51 ± 11.1 and 48.9 ± 9.2, respectively. Scores of CJPET were statistically significantly higher in RA group than healthy volunteers (p = 0.001). CJPET scores were negatively correlated with Berg balance scale findings in right rotation, left rotation, flexion and extension (rho = - 0.421,- 0.473,- 0.448,- 0.515). There was weak or not significant correlation between the scores of CJPET and fatigue, depression, and quality of life scales. Scores of CJPET in patients with atlantoaxial subluxations (AAS) were statistically significantly higher than those without AAS (p < 0.05). Regression analysis results showed that the AAS was related to impaired cervical proprioception on right and left rotations. There was no correlation between CJPET scores and functional parameters. Cervical proprioception impaired in RA patients. This impairment was related to the existence of AAS and balance problems.

Abstract
Non-specific self-reports of dysphagia have been described in people with whiplash-associated disorders (WAD) following motor vehicle collision (MVC); however, incidence and mechanistic drivers remain poorly understood. Alterations in oropharyngeal dimensions on magnetic resonance imaging (MRI), along with heightened levels of stress, pain, and changes in stress-dependent microRNA expression (e.g., miR-320a) have been also associated with WAD, suggesting multi-factorial issues may underpin any potential swallowing changes. In this exploratory paper, we examine key biopsychosocial parameters in three patients with persistent WAD reporting swallowing change and three nominating full recovery after whiplash with no reported swallowing change. Parameters included (1) oropharyngeal volume with 3D MRI, (2) peritraumatic miR-320a expression, and (3) psychological distress. These factors were explored to highlight the complexity of patient presentation and propose future considerations in relation to a potential deglutition disorder following WAD. The three participants reporting changes in swallowing all had smaller oropharyngeal volumes at < 1 week and at 3 months post injury and lower levels of peritraumatic miR-320a. At 3 months post MVC, oropharyngeal volumes between groups indicated a large effect size (Hedge's g = 0.96). Higher levels of distress were reported at both time points for those with persistent symptomatology, including self-reported dysphagia, however, this was not featured in those nominating recovery. This paper considers current evidence for dysphagia as a potentially under-recognized feature of WAD and highlights the need for future, larger-scaled, multidimensional investigation into the incidence and mechanisms of whiplash-associated dysphagia.

Abstract
Background Neck pain is a common complaint worldwide and ranked seventh in 2010 as the cause of ‘years lived with disability’ in Ghana. Proprioceptive dysfunction, measured by joint position error (JPE) tests, indicates an association with neck pain frequency, dizziness and balance problems in patients. Objectives To examine proprioceptive deficits of the neck using a laser pointer attached to the head. Methods Twenty patients within the age group 21–60 years, with at least five points on the neck disability index (NDI), and 20 age- and sex-matched controls with less than five points on the NDI were recruited for this study. The JPE was determined wearing a headlight laser pointer directed towards a Cartesian coordinate system adjusted to x/y = 0/0, placed on a wall after returning from left and right rotation, flexion and extension. From starting in an upright sitting position, facing the Cartesian coordinate system, each participant performed five repetitions for each movement direction. The mean of five repetitions for each movement direction was calculated as absolute error (AE), constant error (CE) and variable error (VE). Results Control participants showed larger JPE values for nearly all AE, CE and VE. After repositioning from flexion controls showed an approximately 0.6 ° larger median JPE, and the opposite for extension, with median differences between 1 ° and 2 °. Conclusion The results of this study do not reveal any meaningful differences between patients with mild disabled neck movement compared with controls. Clinical implications Joint position error testing does not seem useful for patients with mild neck disability.

Abstract
BACKGROUND Chronic migraine (CM) is a primary headache type associated with a severe reduction in the quality of life. The association of sensorimotor dysfunction in the neck, measured with the joint position error test (JPE), and CM is largely unknown, even though up to 60% of migraine patients report neck pain accompanying the migraine. METHODS This manuscript reports a systematic review of the literature on JPE in patients with headache as well as data on an observational study. To determine the JPE of migraine patients, 37 subjects with CM were tested and compared with a control group (CG; n = 22). In an additional analysis, CM patients were divided into two subgroups based on the medical treatment approach. The measurements were taken in the three movement dimensions with five repetitions in each direction using a laser pointer fixed to the head. RESULTS The mean JPE in the sagittal plane was 3.7° (SD ± 1.4°) and 3.1° (SD ± 1.1°) for CM (n = 37) and CG, respectively. In the transverse plane it was measured as 3.7° (SD ± 1.5°) for CM and 3.2° (SD ± 1°) for the CG, while it was 3.6° (SD ± 1.2°; CM) and 3.3° (SD ± 1.1°; CG) in the frontal plane. The between group difference was not significant for all movement planes. When groups according to the treatment regimen, both groups showed similar migraine and neck pain features but the JPE was significantly larger in the CM + BTh group compared to the CM without BTh group and the CG. In the sagittal plane, the JPE was 4.21° (SD ± 1.8°) for the CM + BTh compared to 2.99° (SD ± 1.2°) in CM without BTh and 3.21° (SD ± 1.2°) in the CG (p = 0.0053). The difference between CM + BTh and CM without BTh was 1.52° (p = 0.016) after propensity score matching in the sagittal plane. CONCLUSIONS Only patients in the CM + BTh group showed a statistically increased JPE. The influence of neck pain does not explain the between group difference. A possible factor is the degree of chronification. This study indicates that the JPE might discriminate a subgroup of migraine patients.

Abstract
Background It has been suggested that patients with chronic non-specific low back pain (CNSLBP) perform poorly in postural tasks when compared to healthy individuals. Despite its importance in posture and alignment of the trunk in relation to the head, neck proprioception has not been examined in patients with low back pain. The purpose of this study was to compare neck proprioception in patients with CNSLBP with healthy individuals. Methods Cervical joint reposition error was measured five times consecutively in the neutral head position, 30° and 60° left and right head rotation. The main outcome measure was the mean cervical joint repositioning error of the head. Results Forty-six participants with (n = 24, 54 ± 16yrs SD, 14 females) and without (n = 22, 36 ± 13yrs SD, 13 females) CNSLBP were included in the study. Comparison of mean cervical joint repositioning error between patients and healthy controls showed no statistically significant group difference in any of the applied positions. The range of deviation in CNSLBP patients was between 1.57° and 3.27° compared to 1.46° to 2.26° in healthy controls. An overshooting tendency for both groups was found in the neutral head position. Conclusion The ability to accurately position the head does not seem to be impaired in patients with CNSLBP. This may suggest that sensorimotor control is affected on other levels of the movement system and future research should focus on methods to identify the source of these aberrations.

Abstract
BACKGROUND Equestrian riding is a sport with a high risk of concussion. Currently, the literature guiding rehabilitation for concussions in equestrian athletes is limited, especially for directing return to sport. CASE DESCRIPTION In this case report, a 14-year-old female equestrian athlete presented to physical therapy following her third concussion in 3 years. Her primary complaints were headaches, dizziness, difficulty concentrating, light sensitivity, and neck pain. On examination, the patient demonstrated reproduction of symptoms during testing of the vestibular-ocular reflex, showed a 3-line symptomatic loss on the dynamic visual acuity test, and had impairments in the joint position error test (1/5 correct on the left, 4/5 correct on the right) and a Balance Error Scoring System (BESS) score of 38/60 errors. A return-to-riding protocol was adapted from general return-to-sport guidelines and tailored to meet the unique demands of the patient's equestrian sport. The protocol included phased progression through no activity, light aerobic activity, moderate aerobic activity, sport-specific nonjumping skills, sport-specific jumping skills, full practice, and return to competition. During the protocol, the patient participated in 8 physical therapy sessions over 4 weeks for vestibular training, aerobic conditioning, and cervical and core exercises, as well as equestrian exercises at her stables. OUTCOMES At the final evaluation, the patient reported no symptoms at rest, with exercise, or when testing vestibular-ocular reflex. Improvements were noted in the dynamic visual acuity test, joint position error, and BESS, with changes in the BESS exceeding minimal detectable change. The patient completed the full return-to-riding protocol in 8 weeks and was able to return to equestrian competition without complaints. DISCUSSION This case report describes the physical therapy management of an adapted return-to-sport protocol for an equestrian athlete with a history of multiple sport-related concussions. LEVEL OF EVIDENCE Therapy, level 5. J Orthop Sports Phys Ther 2018;48(12):934-942. Epub 27 Jul 2018. doi:10.2519/jospt.2018.8214.

Abstract
PURPOSE This case report presents evidence-based physical therapy assessments and interventions for a patient with unilateral vestibular hypofunction (UVH). UVH is the result of peripheral vestibular dysfunction in the inner ear. Case Description : The patient was a 48-year-old male with symptoms of dizziness, cephalalgia, and cervicalgia. The examination and treatment were focused on impaired cervical proprioception, which is a vital component of balance training in addition to visual, vestibular, and somatosensory re-education for patients with dizziness. Toward the end of the physical therapy episode of care, the patient was medically diagnosed with Chiari malformation, a congenital cerebellar tonsillar herniation. Outcomes : The patient made significant strides on the Dizziness Handicap Inventory, Ten Meter Walk Test, Single Leg Stance, Balance Error Scoring System, Fukuda Stepping Test, Cervical Joint Position Error Sense Test, Convergence Distance, Global Rate of Change, and cervical range of motion assessments. The patient did not demonstrate comparable improvements on the Dynamic Visual Acuity Test. Conclusion : This case report demonstrates a physical therapy program for a patient with peripheral UVH-related symptoms. This approach may also be applicable for patients with the central cause of dizziness such as Chiari malformation. Future directions for research and clinical practice are also suggested in this report.

Abstract
PURPOSE Though there is abundant literature on cervicogenic dizziness with at least half a dozen of review articles, the condition remains to be enigmatic for clinicians dealing with the dizzy patients. However, most of these studies have studied the cervicogenic dizziness in general without separating the constitute conditions. Since the aetiopathological mechanism of dizziness varies between these cervicogenic causes, one cannot rely on the universal conclusions of these studies unless the constitute conditions of cervicogenic dizziness are separated and contrasted against each other. METHODS This narrative review of recent literature revisits the pathophysiology and the management guidelines of various conditions causing the cervicogenic dizziness, with an objective to formulate a practical algorithm that could be of clinical utility. The structured discussion on each of the causes of the cervicogenic dizziness not only enhances the readers' understanding of the topic in depth but also enables further research by identifying the potential areas of interest and the missing links. RESULTS Certain peculiar features of each condition have been discussed with an emphasis on the recent experimental and clinical studies. A simple aetiopathological classification and a sensible management algorithm have been proposed by the author, to enable the identification of the most appropriate underlying cause for the cervicogenic dizziness in any given case. However, further clinical studies are required to validate this algorithm. CONCLUSIONS So far, no single clinical study, either epidemiological or interventional, has incorporated and isolated all the constitute conditions of cervicogenic dizziness. There is a need for such studies in the future to validate either the reliability of a clinical test or the efficacy of an intervention in cervicogenic dizziness.

Abstract
OBJECTIVE Musculoskeletal disorders are associated with altered sensory, proprioceptive and cognitive processes. Sensory processes affect the internal cortical representation of the body in space, the body schema, which in turn influences motor control. The purpose of this study was to determine if participants with wrist/hand disorders had impaired performance on a task associated with the body schema, the Left/Right Judgement Task (LRJT) and secondly how LRJT performance, motor performance, disability, pain and related aspects are associated. METHODS Fifteen healthy control participants and 15 participants with hand/wrist pain were asked to determine the laterality of images of hands. Measures of motor performance (Purdue Pegboard test), self-reported disability (Australian Canadian Hand Index), and pain related aspects (pain intensity, symptom duration, pain interference and affective distress) were recorded. RESULTS Participants with wrist/hand pain scored lower on all segments of the Purdue Pegboard test. There were differences in LRJT performance between groups for both Accuracy (p = 0.03) and Reaction Time (RT) (p < 0.01). There was no correlation between RT and Accuracy with pain intensity, pain duration, and disability. Both motor performance (r = 0.58-0.64) and LRJT performance Accuracy (r = 0.59) and RT (r = -0.56) were correlated with affective distress. A significant correlation was observed between RT and motor performance in healthy control participants (r = -0.56, p = 0.03) but not in participants with wrist/hand pain (r = -0.26, p = 0.44). CONCLUSIONS LRJT and motor performance was correlated with affective distress in participants with wrist/hand pain suggestive of complex interactions between cognitive-affective processes and sensorimotor integration.

Abstract
BACKGROUND CONTEXT The development of muscle fat infiltration (MFI) in the neck muscles is associated with poor functional recovery following whiplash injury. Custom software and time-consuming manual segmentation of magnetic resonance imaging (MRI) is required for quantitative analysis and presents as a barrier for clinical translation. PURPOSE The purpose of this work was to establish a qualitative MRI measure for MFI and evaluate its ability to differentiate between individuals with severe whiplash-associated disorder (WAD), mild or moderate WAD, and healthy controls. STUDY DESIGN/SETTING This is a cross-sectional study. PATIENT SAMPLE Thirty-one subjects with WAD and 31 age- and sex-matched controls were recruited from an ongoing randomized controlled trial. OUTCOME MEASURES The cervical multifidus was visually identified and segmented into eighths in the axial fat/water images (C4-C7). Muscle fat infiltration was assessed on a visual scale: 0 for no or marginal MFI, 1 for light MFI, and 2 for distinct MFI. The participants with WAD were divided in two groups: mild or moderate and severe based on Neck Disability Index % scores. METHODS The mean regional MFI was compared between the healthy controls and each of the WAD groups using the Mann-Whitney U test. Receiver operator characteristic (ROC) analyses were carried out to evaluate the validity of the qualitative method. RESULTS Twenty (65%) patients had mild or moderate disability and 11 (35%) were considered severe. Inter- and intra-rater reliability was excellent when grading was averaged by level or when frequency of grade II was considered. Statistically significant differences (p<.05) in regional MFI were particularly notable between the severe WAD group and healthy controls. The ROC curve, based on detection of distinct MFI, showed an area-under-the curve of 0.768 (95% confidence interval 0.59-0.94) for discrimination of WAD participants. CONCLUSIONS These preliminary results suggest a qualitative MRI measure for MFI is reliable and valid, and may prove useful toward the classification of WAD in radiology practice.

Abstract
Background Impaired cervical joint position sense and balance are associated with neck pain. Specific therapeutic exercise and manual therapy are effective for improving neck pain and functional ability but their effects on joint position sense and balance impairments remain uncertain. Changes in the joint position sense and balance may need to be addressed specifically. The primary objective is to investigate the most effective interventions to improve impaired cervical joint position sense and balance in individuals with neck pain. The secondary objective is to assess the effectiveness of the interventions on pain intensity and disability, pain location, dizziness symptoms, cervical range of motion, gait speed, functional ability, treatment satisfaction and quality of life. Methods A 2 × 2 factorial, single blind RCT with immediate, short- and long-term follow-ups. One hundred and sixty eight participants with neck pain with impaired joint position sense and balance will be recruited into the trial. Participants will be randomly allocated to one of four intervention groups: i) local neck treatment, ii) local treatment plus tailored sensorimotor exercises, iii) local treatment plus balance exercises, and iv) local treatment plus sensorimotor and balance exercises. Participants receive two treatments for 6 weeks. Primary outcomes are postural sway and cervical joint position error. Secondary outcomes include gait speed, dizziness intensity, neck pain intensity, neck disability, pain extent and location, cervical range of motion, functional ability, perceived benefit, and quality of life. Assessment will be measured at baseline, immediately after treatment and at 3, 6, 12 month-follow ups. Discussion Neck pain is one of the major causes of disability. Effective treatment must address not only the symptoms but the dysfunctions associated with neck pain. This trial will evaluate the effectiveness of interventions for individuals with neck pain with impaired cervical joint position sense and balance. This trial will impact on clinical practice by providing evidence towards optimal and efficient management. Trial registration ClinicalTrials.gov (NCT03149302). May 10, 2017.

Abstract
BACKGROUND Electrooculography is useful in detecting smooth pursuit neck torsion (SPNT) abnormalities in patients with neck pain, however, a validated, clinically relevant measure is lacking. OBJECTIVES To explore the validity of visual assessment of formal and clinical videotaped SPNT tests in comparison to electrooculography. DESIGN Cross-sectional observational study. METHOD Twenty patients with idiopathic neck pain (INP) and twenty healthy controls performed the electrooculography SPNT test: first in neutral, then 45° trunk-under-head torsion to the left then right. The formal video test involved the participant following a horizontal laser stimulus simultaneous to electrooculography. The clinical video test was then performed where the participant followed the clinician's finger in the horizontal direction. One blinded investigator interpreted and analysed the electrooculography trace and two others interpreted the videos. RESULTS Patients with INP had a significantly (p < 0.05) greater SPNT difference than healthy controls. Visual observation of the formal test had 82.5% agreement with electrooculography and showed fair sensitivity (63.5%) and good specificity (89.6) whilst the clinical test had 65% agreement with electrooculography and showed poor sensitivity (27.3%) and good specificity (79.3%). There was an 82.5% agreement between investigators for the formal video taped measure. CONCLUSIONS Visual analysis of assessment of SPNT is sufficient for detecting SPNT abnormalities in patients with INP. Accuracy of the clinical method could be improved by, altering how the visual stimulus is presented and including subjective reporting of symptoms to aid diagnosis resulting in implications for future research.

Abstract
OBJECTIVES The purpose of this study was to evaluate if young people with insidious-onset neck pain who spend long periods on mobile electronic devices (known as "text neck") have impaired cervical proprioception and if this is related to time on devices. METHODS A 2-group comparative observational study was conducted at an Australian university. Twenty-two participants with text neck and 22 asymptomatic controls, all of whom were 18 to 35 years old and spent ≥4 hours per day on unsupported electronic devices, were assessed using the head repositioning accuracy (HRA) test. Differences between groups were calculated using independent sample t-tests, and correlations between neck pain intensity, time on devices, and HRA test were performed using Pearson's bivariate analysis. RESULTS During cervical flexion, those with text neck (n = 22, mean age ± standard deviation [SD]: 21 ± 4 years, 59% female) had a 3.9° (SD: 1.4°) repositioning error, and the control group (n = 22, 20 ± 1 years, 68% female) had a 2.9° (SD: 1.2°) error. The mean difference was 1° (95% confidence interval: 0-2, P = .02). For other cervical movements, there was no difference between groups. There was a moderately significant correlation (P ≤ .05) between time spent on electronic devices and cervical pain intensity and between cervical pain intensity and HRA during flexion. CONCLUSION The participants with text neck had a greater proprioceptive error during cervical flexion compared with controls. This could be related to neck pain and time spent on electronic devices.

Postural control and the relation with cervical sensorimotor control in patients with idiopathic adult-onset cervical dystonia. Exp Brain Res 2018; 236:803-811. [PMID: 29340715 DOI: 10.1007/s00221-018-5174-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2017] [Accepted: 01/09/2018] [Indexed: 02/07/2023]
Abstract
Cervical dystonia (CD) is a movement disorder characterized by involuntary muscle contractions leading to an abnormal head posture or movements of the neck. Dysfunctions in somatosensory integration are present and previous data showed enlarged postural sway in stance. Postural control during quiet sitting and the correlation with cervical sensorimotor control were investigated. Postural control during quiet sitting was measured via body sway parameters in 23 patients with CD, regularly receiving botulinum toxin treatment and compared with 36 healthy controls. Amplitude and velocity of displacements of the center of pressure (CoP) were measured by two embedded force plates at 1000 Hz. Three samples of 30 s were recorded with the eyes open and closed. Disease-specific characteristics were obtained in all patients by the Tsui scale, Cervical Dystonia Impact Profile (CDIP-58) and Toronto Western Spasmodic Rating Scale (TWSTRS). Cervical sensorimotor control was assessed with an infrared Vicon system during a head repositioning task. Body sway amplitude and velocity were increased in patients with CD compared to healthy controls. CoP displacements were doubled in patients without head tremor and tripled in patients with a dystonic head tremor. Impairments in cervical sensorimotor control were correlated with larger CoP displacements (rs ranged from 0.608 to 0.748). Postural control is impaired and correlates with dysfunction in cervical sensorimotor control in patients with CD. Treatment is currently focused on the cervical area. Further research towards the potential value of postural control exercises is recommended.

The influence of cervical movement on eye stabilization reflexes: a randomized trial. Exp Brain Res 2017; 236:297-304.

Abstract
To investigate the influence of the amount of cervical movement on the cervico-ocular reflex (COR) and vestibulo-ocular reflex (VOR) in healthy individuals. Eye stabilization reflexes, especially the COR, are changed in neck pain patients. In healthy humans, the strength of the VOR and the COR are inversely related. In a cross-over trial the amplitude of the COR and VOR (measured with a rotational chair with eye tracking device) and the active cervical range of motion (CROM) was measured in 20 healthy participants (mean age 24.7). The parameters were tested before and after two different interventions (hyperkinesia: 20 min of extensive active neck movement; and hypokinesia: 60 min of wearing a stiff neck collar). In an additional replication experiment the effect of prolonged (120 min) hypokinesia on the eye reflexes were tested in 11 individuals. The COR did not change after 60 min of hypokinesia, but did increase after prolonged hypokinesia (median change 0.220; IQR 0.168, p = 0.017). The VOR increased after 60 min of hypokinesia (median change 0.155, IQR 0.26, p = 0.003), but this increase was gone after 120 min of hypokinesia. Both reflexes were unaffected by cervical hyperkinesia. Diminished neck movements influences both the COR and VOR, although on a different time scale. However, increased neck movements do not affect the reflexes. These findings suggest that diminished neck movements could cause the increased COR in patients with neck complaints.

Abstract
BACKGROUND Evaluation of cervical joint position sense in subjects with chronic neck pain has gained importance in recent times. Different authors have established increased joint position error (JPE) in subjects with acute neck pain. However, there is a paucity of studies to establish the influence of chronic neck pain on cervical JPE. OBJECTIVE The objective of the study was to understand the influence of chronic neck pain on cervical JPE, and to examine the differences in cervical JPE between young and elderly subjects with chronic neck pain. METHODS Forty-two chronic neck pain patients (mean age 47.4) were compared for cervical JPE with 42 age-matched healthy subjects (mean age 47.8), using a digital inclinometer. The cervical JPE were measured in flexion, extension, and rotation in right and left movement directions. RESULTS The comparison of JPE showed significantly larger errors in subjects with chronic neck pain when compared to healthy subjects (p< 0.001). The errors were larger in all of the movement directions tested. Comparison between young and older subjects with chronic neck pain revealed no significant differences (P> 0.05) in cervical JPE. CONCLUSIONS Cervical joint position sense is impaired in subjects with chronic neck pain.

Abstract
BACKGROUND Inconsistencies in the literature concerning the effect of neck pain have led to a lack of understanding concerning the complete pathophysiology of neck pain. While the effect of neck pain on motor function as measured by active range of motion and isometric neck strength is well documented the effect of neck pain on sensory measures such as tactical acuity and neck reposition error (NRE) remain poorly understood. OBJECTIVE The purpose of this study was to evaluate a combined sensorimotor evaluation to explore the potential benefits of incorporating both sensory and motor task into a physical evaluation of neck pain suffers to gain an added knowledge of the complete pathophysiology of their health status. METHODS A cross-sectional study that measured neck joint reposition error, tactical acuity, neck isometric strength and range of motion in 40 volunteer participants (22 pain, 18 control). RESULTS A statistically significant increase in NRE in flexion (2.75∘± 1.52∘ vs. 4.53∘± 1.74∘ and in extension (3.78∘± 1.95∘ vs 5.77∘± 2.73∘ in participants suffering from neck pain was observed. Additionally, the dermatome C5 was found to be the most affected. No differences were found in neck strength or neck range of motion between healthy controls and patients with chronic moderate neck pain.

Abstract
OBJECTIVES Patients with idiopathic adult-onset cervical dystonia (CD) experience an abnormal head posture and involuntary muscle contractions. Although the exact areas affected in the central nervous system remain uncertain, impaired functions in systems stabilizing the head and neck are apparent such as the somatosensory and sensorimotor integration systems. The aim of the study is to investigate cervical sensorimotor control dysfunction in patients with CD. MATERIAL AND METHODS Cervical sensorimotor control was assessed by a head repositioning task in 24 patients with CD and 70 asymptomatic controls. Blindfolded participants were asked to reposition their head to a previously memorized neutral head position (NHP) following an active movement (flexion, extension, left, and right rotation). The repositioning error (joint position error, JPE) was registered via 3D motion analysis with an eight-camera infrared system (VICON ® T10). Disease-specific characteristics of all patients were obtained via the Tsui scale, Cervical Dystonia Impact Profile (CDIP-58), and Toronto Western Spasmodic Rating Scale. RESULTS Patients with CD showed larger JPE than controls (mean difference of 1.5°, p < .006), and systematically 'overshoot', i.e. surpassed the NHP, whereas control subjects 'undershoot', i.e. fall behind the NHP. The JPE did not correlate with disease-specific characteristics. CONCLUSIONS Cervical sensorimotor control is impaired in patients with CD. As cervical sensorimotor control can be trained, this might be a potential treatment option for therapy, adjuvant to botulinum toxin injections.
