Incidence of Neck Pain in Patients With Concussion in a Pediatric Emergency Department.

OBJECTIVES: The aims of the study were (1) to determine the frequency of neck pain in patients diagnosed with mild traumatic brain injury (mTBI) or concussion in a pediatric level 1 trauma center emergency department (ED), (2) to identify variables associated with neck pain in this population, and (3) to report on aspects of care received in the ED including imaging and medication use. METHODS: This is a retrospective chart review of 652 patients presenting to a pediatric ED with diagnosis of concussion/mTBI. Charts were reviewed for the following information: baseline demographic information, mechanism of injury, cause of mTBI, presence or absence of neck pain, point tenderness in the neck on physical examination, and whether the patient followed up within our health system in the 6 months after injury. Charts were also reviewed for other concussion-related symptoms, medication given in the ED, imaging performed in the ED, cervical spine clearance in the ED, and referrals made. For those patients who did have follow-up appointments within our system, additional chart review was performed to determine whether they sought follow-up treatment for symptoms related to concussion/neck pain and the duration of follow-up. Statistical analyses focused on the prevalence of neck pain in the sample. We subsequently explored the degree to which neck pain was associated with other collected variables. RESULTS: Of 652 patients, 90 (13.8%) reported neck pain. Acceleration/deceleration injury and motor vehicle accident were predictive of neck pain. Neck pain was less common in those reporting nausea and vomiting. Direct impact of the head against an object was associated with reduced odds of neck pain, but after adjusting for other variables, this was no longer statistically significant. Patients with neck pain were older than those without neck pain. Patients with neck pain were more likely to receive ibuprofen or morphine and undergo imaging of the spine. They were also more likely to receive a referral and follow-up with neurosurgery. There was no significant difference between groups with respect to concussion-related follow-up visits or follow-up visits to a dedicated concussion clinic. CONCLUSIONS: Neck pain is a common symptom in pediatric patients with mTBI, although it was more likely in older patients and those presenting with acceleration/deceleration mechanisms. Although patients with neck pain were more likely to receive a referral and follow-up with neurosurgery, they were not more likely to have concussion-related follow-up visits. Indeed, most patients had no follow-up visits related to their concussion, which supports the notion that concussion is a self-limiting condition.

Frequency of Primary Neck Pain in Mild Traumatic Brain Injury/Concussion Patients.

OBJECTIVES: To determine (1) the frequency of neck pain overall and relative to other symptoms in patients presenting to a level I trauma center emergency department (ED) with mild traumatic brain injury (mTBI) and (2) the predictors of primary neck pain in this population. DESIGN: Cohort study. SETTING: Level I trauma center ED. PARTICIPANTS: Patients presenting to the ED with symptoms of mTBI having been exposed to an event that could have caused mTBI (N=95). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Frequency of self-reported neck pain as measured by Sport Concussion Assessment Tool 3 (SCAT3) symptom questionnaire at <3, 8, 15, and 45 days post injury. Primary neck pain was defined in 2 ways: (1) neck pain rated as equal or greater in severity than all other SCAT3 symptoms and (2) neck pain worse than all other symptoms. RESULTS: The frequency of any reported neck pain was 68.4%, 50.6%, 49%, and 41.9% within 72 hours and at 8, 15, and 45 days, respectively. Frequency of primary neck pain (equal or worse/worse definitions) was 35.8%/17.9%, 34.9%/14.5%, 37%/14.8%, and 39.2%/10.8% across the 4 follow-up assessments. Participants who sustained their injuries in motor vehicle collisions had a higher rate of primary neck pain than those with other mechanisms of injury. CONCLUSIONS: A sizable percentage of patients who present to level I trauma center EDs with mTBI report neck pain, which is commonly rated as similar to or worse than other mTBI-related symptoms. Primary neck pain is more common after motor vehicle collisions than with other mechanisms of injury. These findings support consensus statements identifying cervical injury as an important potential concurrent diagnosis in patients with mTBI.

The Prevalence and Influence of New or Worsened Neck Pain After a Sport-Related Concussion in Collegiate Athletes: A Study From the CARE Consortium.

BACKGROUND: Neck pain in a concussion population is an emerging area of study that has been shown to have a negative influence on recovery. This effect has not yet been studied in collegiate athletes. HYPOTHESIS: New or worsened neck pain is common after a concussion (>30%), negatively influences recovery, and is associated with patient sex and level of contact in sport. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Varsity-level athletes from 29 National Collegiate Athletic Association member institutions as well as nonvarsity sport athletes at military service academies were eligible for enrollment. Participants completed a preseason baseline assessment and follow-up assessments at 6 and 24 to 48 hours after a concussion, when they were symptom-free, and when they returned to unrestricted play. Data collection occurred between January 2014 and September 2018. RESULTS: A total of 2163 injuries were studied. New or worsened neck pain was reported with 47.0% of injuries. New or worsened neck pain was associated with patient sex (higher in female athletes), an altered mental status after the injury, the mechanism of injury, and what the athlete collided with. The presence of new/worsened neck pain was associated with delayed recovery. Those with new or worsened neck pain had 11.1 days of symptoms versus 8.8 days in those without (P < .001). They were also less likely to have a resolution of self-reported symptoms in ≤7 days (P < .001). However, the mean duration of the return-to-play protocol was not significantly different for those with new or worsened neck pain (7.5 ± 7.7 days) than those without (7.4 ± 8.3 days) (P = .592). CONCLUSION: This novel study shows that neck pain was common in collegiate athletes sustaining a concussion, was influenced by many factors, and negatively affected recovery.

COVID-19 Infectious Disease Prevention and Mitigation Practices by Chiropractic Physicians and Licensed Massage Therapists in Mississippi: A Needs Assessment to Inform Health Education and Promotion.

Objective: The purpose of this study was to assess self-reported infection prevention processes and their effect on businesses of chiropractic doctors (DCs) and licensed massage therapists (LMTs) in Mississippi during the COVID-19 pandemic. Methods: We developed a survey that was electronically delivered to all licensed DCs and LMTs in Mississippi between August and September 2020. Assessments were made using Qualtrics software, with data management and subsequent analysis including Pearson's χ2 test. Results: Responses were based on 32 of 323 DCs and 69 of 934 LMTs that were still seeing patients through the pandemic (n = 101, response rate 8%). The DC and LMT practitioners (94%) used treatment table and/or surface sanitizing (91.8%) and hand washing and/or sanitizing (89.8%) between all patients. Female practitioners reported practicing handwashing for at least 20 seconds, whereas male practitioners reported practicing handwashing for at least 15 seconds (P < .001). DCs were more likely to report using gloves for personal protective equipment, and LMTs were more likely to report using face masks (P < .001). Other COVID-19 procedures included limiting practice to acute care (82.5%), checking all patient temperatures (62.9%), sign-in and wait in the car (53.2% LMT vs 6.5% DC, P < .001), and prohibiting all nonpatient visitors (87.7% LMTs vs 9.4% DCs, P < .001). DCs (96.9%) and LMTs (89.9%) reported making referrals for COVID-19 testing or treatment when indicated. LMTs (82.3%) reported seeing fewer patients (P = .03), and older practitioners reported the most economic impact (P = .003) by the pandemic. Patient concerns and LMTs needing more time to perform infection control (P = .04) were reasons cited by practitioners for the reduced number of visits seen. Conclusion: Most respondents had moderate to high compliance with guidelines on recommended infection prevention processes during fall 2020 of the COVID-19 pandemic. This assessment of compliance may be used to help guide future health education and promotion research of disease prevention and mitigation as well as physical and economic burdens faced by DCs and LMTs in Mississippi during a pandemic.

Spinal manipulative therapy and cervical artery dissection: A retrospective comparison with spontaneous, traumatic, and iatrogenic etiologies at a single academic medical center.

OBJECTIVE: Cervical artery dissection (CAD) has been associated with spinal manipulative therapy (SMT). Although uncommonly reported, SMT-associated CADs hold devastating neurological consequences, warranting further exploration. We endeavored to investigate this association through the comparison of all CAD etiologies at a single academic medical center. METHODS: A retrospective chart review was conducted of patients diagnosed with CAD or transferred to our institution for primary management of CAD during the 10-year period from 2010 to 2020 (n = 578). Patients were divided into SMT-associated (within 1 month of presentation), spontaneous, traumatic, and iatrogenic cohorts. RESULTS: SMT-associated dissections represented 23/578 (4%) of all dissections and 5.9% of vertebral artery dissections specifically. These patients were generally younger than those in the spontaneous (p = .004) and iatrogenic groups (p < .001), and more often non-smokers or former smokers compared to the spontaneous (p = .009), traumatic (p = .001), and iatrogenic (p = .008) groups. Additionally, the SMT group had a higher mean low-density lipoprotein (LDL) than the spontaneous (p = .009) and traumatic (p = .003) types. SMT-associated CADs were more often vertebral and bilateral, compared to the spontaneous (p = .003; p < .001), traumatic (p = .047; p = .004), and iatrogenic (p = .002; p = .002) groups. Outcomes including infarct (p = .112), medical treatment (p = .523), intervention (p = .47), and length of stay (p = .512) were similar between the SMT and spontaneous groups. CONCLUSIONS: In this unique study comparing SMT-associated CADs with other dissection etiologies, SMT-associated CADs were uncommon and not associated with worse clinical outcomes. However, SMT-associated CADs were more likely to be bilateral and affected the vertebral arteries in young, non-smoking patients with high LDL.

Comparing preseason frontal and sagittal plane plyometric programs on vertical jump height in high-school basketball players.

The primary purpose of this study was to evaluate whether frontal plane (FP) plyometrics, which are defined as plyometrics dominated with a lateral component, would produce similar increases in vertical jump height (VJH) compared to sagittal plane (SP) Plyometrics. Thirty-two junior varsity and varsity high-school basketball players participated in 6 weeks of plyometric training. Players participated in either FP or SP plyometrics for the entire study. Vertical jump height was measured on 3 occasions: preintervention (baseline), at week 3 of preparatory training, and at week 6 of training. Descriptive statistics were calculated for VJH. A 2-way analysis of variance (ANOVA) with repeated measures was used to test the difference in mean vertical jump scores using FP and SP training modalities. Results showed a significant effect over time for vertical jump (p < 0.001). Moreover, a significant time by protocol interaction was noted (p < 0.032). A 1-way ANOVA demonstrated that only the SP group demonstrated improvements over time, in VJH, p < 0.05. The FP group did not improve statistically. The data from this study suggest that FP plyometric training did not have a significant effect on VJH and significant improvement in VJH was seen in subjects participating in SP plyometrics thus reinforcing the specificity principle of training. However, coaches should implement both types of plyometrics because both training modalities can improve power and quickness among basketball players.

Oswestry Disability Index scores correlate with MRI measurements in degenerating intervertebral discs and endplates.

BACKGROUND: Low back pain (LBP) is a widespread problem and the leading cause of disability worldwide. While the cause of LBP is multifactorial, several studies suggested that inflammatory mediators in damaged subchondral plates of degenerating discs may lead to chemical sensitization and mechanical stimulation, eventually causing pain. The goal of this study was to explore associations between such changes and LBP-related disability using dynamic contrast-enhanced MRI. METHODS: Thirty-two patients diagnosed with nonspecific LBP and 24 healthy control subjects were studied with dynamic contrast-enhanced (DCEMRI) MRI and T1r (spin-lattice relaxation in the rotating frame) acquisitions. DCEMRI enhancement in disc endplate regions and average T1ρ measurements in the nucleus pulposus were extracted. The LBP patients were grouped based on their Oswestry Disability Index (ODI) scores and associations between MRI measurements and ODI scores were analyzed. RESULTS: Significant associations were found between ODI scores and DCEMRI enhancement in the cartilaginous endplate regions of the most degenerated discs. ODI scores also correlated with T1ρ measurements in the nucleus pulposus of degenerating discs. CONCLUSIONS: DCEMRI enhancement in the cartilaginous endplate regions and lower T1ρ measurements in the nucleus pulposus (NP) were associated with greater disability that is related to low back pain as reported on the ODI. This complements earlier reports suggesting a link between LBP and endplate degeneration. Further studies are needed to validate these findings. SIGNIFICANCE: Our findings indicated that dynamic contrast-enhanced MRI signal enhancement in the cartilaginous endplate regions were associated with greater disability related to low back pain. This signal enhancement might be an indication of inflammatory changes in disc endplate regions. Therefore, advanced quantitative imaging techniques like the ones presented in this study might be needed to complement conventional radiological evaluations to identify the subset of patients who could potentially benefit from novel therapies directed towards treating the disc endplate regions.

Guideline summary review: an evidence-based clinical guideline for the diagnosis and treatment of low back pain.

BACKGROUND CONTEXT: The North American Spine Society's (NASS) Evidence Based Clinical Guideline for the Diagnosis and Treatment of Low Back Pain features evidence-based recommendations for diagnosing and treating adult patients with nonspecific low back pain. The guideline is intended to reflect contemporary treatment concepts for nonspecific low back pain as reflected in the highest quality clinical literature available on this subject as of February 2016. PURPOSE: The purpose of the guideline is to provide an evidence-based educational tool to assist spine specialists when making clinical decisions for adult patients with nonspecific low back pain. This article provides a brief summary of the evidence-based guideline recommendations for diagnosing and treating patients with this condition. STUDY DESIGN: This is a guideline summary review. METHODS: This guideline is the product of the Low Back Pain Work Group of NASS' Evidence-Based Clinical Guideline Development Committee. The methods used to develop this guideline are detailed in the complete guideline and technical report available on the NASS website. In brief, a multidisciplinary work group of spine care specialists convened to identify clinical questions to address in the guideline. The literature search strategy was developed in consultation with medical librarians. Upon completion of the systematic literature search, evidence relevant to the clinical questions posed in the guideline was reviewed. Work group members utilized NASS evidentiary table templates to summarize study conclusions, identify study strengths and weaknesses, and assign levels of evidence. Work group members participated in webcasts and in-person recommendation meetings to update and formulate evidence-based recommendations and incorporate expert opinion when necessary. The draft guideline was submitted to an internal and external peer review process and ultimately approved by the NASS Board of Directors. RESULTS: Eighty-two clinical questions were addressed, and the answers are summarized in this article. The respective recommendations were graded according to the levels of evidence of the supporting literature. CONCLUSIONS: The evidence-based clinical guideline has been created using techniques of evidence-based medicine and best available evidence to aid practitioners in the diagnosis and treatment of adult patients with nonspecific low back pain. The entire guideline document, including the evidentiary tables, literature search parameters, literature attrition flowchart, suggestions for future research, and all of the references, is available electronically on the NASS website at https://www.spine.org/ResearchClinicalCare/QualityImprovement/ClinicalGuidelines.aspx.
