Failed back surgery syndrome successfully ameliorated with Chiropractic Biophysics® structural rehabilitation improving pain, disability as well as sagittal and coronal balance: a Chiropractic Biophysics® case report with a 6†year follow-up.

[Purpose] To present the case of the amelioration of chronic pain and disability in a patient suffering from failed back surgery syndrome. [Participant and Methods] A 27-year-old male with chronic low back pain was treated with a Coflex® intra-spinous instrument, however, it was removed shortly after due to poor outcome including worsening pain and disability. Radiographic assessment revealed significant posterior translation of the thorax complicated by significant loss of the normal lumbar lordosis and a left lateral translated thoracic cage posture. Chiropractic Biophysics® technique was applied over a 5.5-month period leading to structural spine improvements as well as improved pain, Oswestry disability index (ODI) and quality of life (QOL). [Results] There was a 21 mm reduction in posterior thoracic translation, a 6.2° improvement in lumbar lordosis and a 16 mm reduction in lateral thoracic translation corresponding with improved ODI and QOL scores. A 6 year follow-up showed successful outcome despite some degenerative changes in the spine at the prior surgical level. [Conclusion] This case adds to the growing literature showing the efficacy of non-surgical spinal rehabilitative methods in improving outcomes in patients with spinal deformity and associated disabilities. This case also demonstrates necessity of the continued criterion standard of spinal radiography for biomechanical assessment.

Alleviation of shoulder injury related to vaccine administration (SIRVA) pain and disability following COVID-19 vaccine with chiropractic biophysics® (CBP®) methods: a case report and long-term follow-up with global implications.

[Purpose] To present the dramatic improvement in posture, radiographic parameters and the alleviation of neck and severe shoulder pain related to shoulder injury associated with vaccine administration (SIRVA) after a COVID-19 injection with a shoulder mobility and posture rehabilitation program. [Participant and Methods] A middle-aged male presented complaining of severe left shoulder pain evolving since receiving a COVID-19 vaccination. The pain was severe and throbbed into the neck. Posture analysis showed a chronic stooped posture with forward head posture and thoracic hyperkyphosis. Treatment included 42 sessions of Chiropractic Biophysics® technique and a shoulder rehabilitation program using three-dimensional vibration. [Results] At 4-months, the patient reported no neck or shoulder pain. There was a 60% decrease in neck disability. The forward head decreased 34 mm, thoracic hyperkyphosis decreased 13°, and T1-T12 forward lean decreased 73 mm, among other radiographic parameters. Re-assessment after 26-months showed maintenance of the treatment induced posture/x-ray corrections and shoulder pain relief. [Conclusion] This case demonstrates immediate and long-term improvement in a patient suffering from COVID-19 vaccine SIRVA, concomitant with neck pain and disability as well as significant radiographic postural/spinal deformity. These conditions all improved and were maintained at a 2 year follow-up without further treatment.

Reduction of thoraco-lumbar kyphosis results in the alleviation of low back pain in an adolescent basketball player: a Chiropractic Biophysics® (CBP®) case report.

[Purpose] To present the case of a significant reduction in thoraco-lumbar deformity and alleviation of chronic low back pain in an otherwise healthy and active adolescent male basketball player. [Participant and Methods] A 17 year old was assessed with chronic low back pain persisting for 4 years. Radiographic assessment revealed a prominent thoraco-lumbar kyphosis. Chiropractic Biophysics® structural rehabilitation including mirror image® exercise and traction methods as well as spinal manipulative therapy was performed 2-3 times per week. [Results] There was a 12° improvement in the thoraco-lumbar deformity corresponding with the alleviation of chronic low back pains and near complete reduction in disability after 36 treatments over a 4-month period. [Conclusion] This case adds to the growing literature showing the efficacy of the non-surgical spinal rehabilitative methods of Chiropractic Biophysics in improving spine alignment and relieving spinal pain syndromes. This case also demonstrates the importance of the routine screening for spine alignment via radiography in leading to proper biomechanical diagnosis and treatment.

A 13-Year Long-Term Follow-Up of a Case Report With Continued Improvement in Severe Chronic Neck and Head Pain Alleviated With Chiropractic BioPhysics® Spinal Rehabilitation Protocols.

Alleviation of headaches (HAs), neck pain (NP), and disability is a desirable clinical outcome for the billions globally who suffer from these conditions. Chiropractic BioPhysics® (CBP®) methods may provide an option for head and neck-injured patients. A 62-year-old female historically injured multiple times including two motor vehicle collisions (MVC), and a strike to the face with a hockey puck; all resulting in chronic pain and suffering. The subject sought and received successful treatment in 2016 using this conservative protocol at a facility in the USA. The resolution of symptoms following 36 treatments was previously reported. Following 13 years without treatment beyond home exercises, the subject was re-evaluated and found to be stable in the long term for pain, structural and functional assessment. Thirty-six treatments over 12 weeks in 2016 led to an improvement in numerical pain rating scale (NPRS) for NP (5/10 to 1/10), and HA (9+/10 to 0/10), resolution of NP disability (6/100 to 0/100) as well as normalization of ROM without pain and resumption of all activities of daily living including high-level athletics without pain and disability. A 13-year follow-up found continued stability objectively and subjectively. We provide a case of successful conservative treatment using specific traction, exercises, and spine manipulation procedures. CBP® provides an option to treat pain and this case adds to growing evidence.

Resolution of Sporadic Hemiplegic Migraine by Correcting a Cervical Spine Kyphosis Utilizing the Chiropractic BioPhysics® (CBP®) Technique: A Case Report With Long-Term Follow-Up.

A 19-year-old male suffered from sporadic hemiplegic migraine (SHM) for several years and experienced significant pain and disability with sensory and motor disturbances during the migraine headaches. Weakness, abnormal vision, abnormal sensation, one-sided disabling motor weakness, and other signs of SHM were diagnosed. The patient had received previous physical therapy, chiropractic and over-the-counter medications, as well as migraine-specific prescriptions without lasting improvements. Chiropractic BioPhysics® (CBP®) spinal structural rehabilitation protocols were used to increase cervical lordosis and improve cervical muscular strength, mobility, and posture. These protocols include spine-specific prescriptions for Mirror Image® postural exercises, traction, and spinal manipulative therapy. After 24 treatments over eight weeks, all subjective and objective outcomes improved dramatically with a near resolution of all initial symptoms of SHM. There were a significant increase in cervical lordosis and a reduction in forward head posture. The neck disability index improved from 26% to 6%, and all pain scores for all regions improved following treatment. A 10-month follow-up exam showed the outcomes were maintained. SHM is rare and debilitating, is part of the global burden of disease, and is a major cause of disability in the world. Reports of successful conservative and non-conservative long-term treatments for SHM are rare, and there are no clinical trials showing successful treatments for SHM. This successful case demonstrates preliminary evidence that CBP spinal structural rehabilitation may serve as a treatment option for SHM. Future studies are needed to replicate the findings from this case.

Two Methods of Forward Head Posture Assessment: Radiography vs. Posture and Their Clinical Comparison.

Background: Forward head posture (FHP) and altered cervical lordotic curvatures are common spine displacements often associated with neck pain and disability. Two primary categories for determining FHP exist: radiographic and postural measurements. Methods: This study investigated the correlation between the craniovertebral angle (CVA), the radiographically measured C2-C7 sagittal vertical axis (SVA), and cervical lordosis (absolute rotation angle: ARA C2-C7) in a sample of participants with chronic myofascial pain (CMP). In 120 participants, we performed both a postural measurement of the CVA and a lateral cervical radiograph, where the C2-C7 SVA and ARA C2-C7 were measured. A linear-regression R2 value to assess the correlation between the CVA, C2-C7 SVA, and ARA C2-C7 was sought. Results: A statistically significant weak linear fit was identified (Spearman's r = 0.549; R2 = 0.30, p < 0.001) between the CVA and C2-C7 SVA, having considerable variation between the two measures. A statistically significant linear fit (very weak) was identified for the lordosis ARA C2-C7 and the CVA: Spearman's r = 0.524; R2 = 0.275; p < 0.001. A value of 50° for the CVA corresponded to a value of 20 mm for the C2-C7 SVA on an X-ray. Conclusion: While the CVA and radiographic C2-C7 SVA are weakly correlated in an individual, they seem to represent different aspects of sagittal cervical balance. The CVA cannot replace radiographically measured cervical lordosis. We recommend that more emphasis be given to radiographic measures of sagittal cervical alignment than the CVA when considering patient interventions.

Can the Mismatch of Measured Pelvic Morphology vs. Lumbar Lordosis Predict Chronic Low Back Pain Patients?

Background: Measures of lumbar lordosis (LL) and elliptical modeling variables have been shown to discriminate between normal and chronic low back pain (CLBP) patients. Pelvic morphology influences an individual's sagittal lumbar alignment. Our purpose is to investigate the sensitivity and specificity of lumbar sagittal radiographic alignment and modeling variables to identify if these can discriminate between normal controls and CLBP patients. Methods: We conducted a computer analysis of digitized vertebral body corners on lateral lumbar radiographs of normal controls and CLBP patients. Fifty normal controls were attained from a required pre-employment physical examination (29 men; 21 women; mean age of 27.7 ± 8.5 years), with no history of low back pain, a normal spinal examination, no pathologies, anomalies, or instability. Additionally, 50 CLBP patients (29 men; 29.5 ± 8 years of age) were randomly chosen and matched to the characteristics of the controls. The inclusion criteria required no abnormalities on lumbar spine radiographs. The parameters included the following: ARA L1-L5 lordosis, ARA T12-S1 lordosis, Cobb T12-S1, b/a elliptical modelling ratio, sacral base angle (SBA), and S1 posterior tangent to vertical (PTS1). Two measures of pelvic morphology were determined for each person-the angle of pelvic incidence (API) and posterior tangent pelvic incidence angle (PTPIA)-and the relationships between API - ARA T12-S1, API - Cobb T12-S1, and API - ARA L1-5 was determined. Descriptive statistics and correlations among the primary variables were determined. The receiver operating characteristic curves (ROC curves) for primary variables were analyzed. Results: The mean values of LL were statistically different between the normal and CLBP groups (p < 0.001), indicating a hypo-lordotic lumbar spine for the CLBP group. The mean b/a ratio was lower in the chronic pain group (p = 0.0066). The pelvic morphology variables were similar between the groups (p > 0.05). API had a stronger correlation to the SBA and Cobb T12-S1 than PTPIA did, while PTPIA had a stronger correlation to the S1 tangent and ARA T12-S1 than API did. While CLBP patients had a stronger correlation of ARA T12-S1 and Cobb T12-S1 relative to the pelvic morphology, they also had a reduced correlation of ARA L1-L5 lordosis relative to their SBA and pelvic morphology measures. API - T12-S1, API - L1-L5, and API - Cobb T12-S1 were statistically different between the groups, p < 0.001. Using ROC curve analyses, it was identified that ARA L1-L5 lordosis of 36° and ARA T12-S1 of 68° have a good sensitivity and specificity to discriminate between normal and CLBP patients. ROC curve analyses identified that lordosis ARAT12-S1 < 68° (AUC = 0.83), lordosis ARAL1-L5 < 36° (AUC = 0.78), API - ARA T12-S1 < -18° (AUC = 0.75), API - ARAL1-L5 > 35° (AUC = 0.71), and API - Cobb T12-S1 < -5° (AUC = 0.69) had moderate to good discrimination between groups (AUC = 0.83, 0.78, 0.75, and 0.72). Conclusions: Pelvic morphology is similar between normal and CLBP patients. CLBP patients have an abnormal 'fit' of their API - ARAT12-S1 and L1-L5 lumbar lordosis relative to their pelvic morphology and sacral tilt shown as a hypolordosis.

Chronic Widespread Spinal Pain (CWSP) Alleviated With Chiropractic Biophysics®: A Case Report With Three-Year Follow-Up.

The aim of this case report is to provide clinicians with an option for the treatment of spine pain, spine disorders caused or complicated by abnormal spine alignment, and failed prior interventions for pain and suffering with a conservative protocol. Multi-decade chronic widespread pain (CWSP), low back pain (LBP) headache (HA), and neck pain (NP) cause significant disability and reduced quality of life across all socio-economic and societal categories. Treatment options for decades-old long-term pain with good outcomes are uncommon with non-surgical and surgical interventions. Herein is a single case of positive outcomes with Chiropractic BioPhysics® (CBP®)protocol and long-term follow-up. A 60-year-old male with a lifting injury working on a farm at age 12 suffered for decades with LBP, mid-back pain (MBP), NP, HAs, radiculopathy, and poor health-related quality of life (HRQoL). Prior over-the-counter (OTC) medications with diminishing results over 48 years were reported. The patient had multiple abnormal patient-reported outcomes (PROs) as well as measured postural and spine structural abnormalities at the initial assessment. Following 12 treatments, PROs and other measures improved dramatically. Continued brief treatment showed continued progress followed by no treatment beyond continued home exercises and home postural orthoses. All subjective and objective outcome measures improved at one-year follow-up and remained long-term. Improvements in sagittal and coronal postural balance with improved spine alignment, better PROs, and measurably improved HRQoLs were found at one- and three-year follow-ups from the initial evaluation. Chronic NP, LBP, MBP, and extremity pain with altered sensation, loss of function, and failed drug therapy are common across the globe and combined represent the greatest contributors to disability and the global burden of disease (GBD). Economic, efficacious, repeatable, and reliable methods for treating pain will reduce GBD and improve PROs. Larger studies of CBP® methods for multi-decade chronic pain are challenging; however, continued case reports and RCTs for similar conditions are warranted.

Sagittal Full-Spine vs. Sectional Cervical Lateral Radiographs: Are the Measurements of Cervical Alignment Interchangeable?

(1) Background: This study assessed the relationship between cervical spine parameters taken on standing full-spine lateral radiographic images compared to sectional lateral cervical radiographs. (2) Methods: Full-spine (FS) and sectional lateral cervical (LC) radiographs from four spine treatment facilities across the USA retrospectively provided data collected on 220 persons to assess the comparison of three sagittal cervical radiographic measurements between the two views. The measures included cervical lordosis using the absolute rotation angle from C2-C7, sagittal cervical translation of C2-C7, and atlas plane angle to horizontal. Linear correlation and R2 models were used for statistical comparison of the measures for the two views. (3) Results: The mean values of the three measurements were statistically different from each other: C2-C7 translation (FS = 19.84 ± 11.98 vs. LC = 21.18 ± 11.8), C2-C7 lordosis (FS = -15.3 ± 14.63 vs. LC = -18.32 ± 13.16), and atlas plane (FS = -19.99 ± 8.88 vs. LC = -22.56 ± 8.93), where all values were p < 0.001. Weak-to-moderate-to-strong correlations existed between the full-spine and sectional lateral cervical radiographic variables. The R2 values varied based on the measurement were R2 = 0.768 (p < 0.001) for sagittal cervical translation of C2-C7 (strong), R2 = 0.613 (p < 0.001) for the absolute rotation angle C2-C7 (moderate), and R2 = 0.406 (p < 0.001) for the atlas plane line (weak). Though a linear correlation was identified, there were consistent intra-person differences between the measurements on the full spine versus sectional lateral cervical radiographic views, where the full-spine view consistently underestimated the magnitude of the variables. (4) Conclusion: Key sagittal cervical radiographic measurements on the full spine versus sectional lateral cervical radiographic views show striking intra-person differences. The findings of this study confirm that full spine versus sectional lateral cervical radiographic views provide different biomechanical magnitudes of cervical sagittal alignment, and caution should be exercised by health care providers as these are not interchangeable. We recommend the LC view for measurement of cervical sagittal alignment variables.

Intra-Examiner Reliability and Validity of Sagittal Cervical Spine Mensuration Methods Using Deep Convolutional Neural Networks.

Background: The biomechanical analysis of spine and postural misalignments is important for surgical and non-surgical treatment of spinal pain. We investigated the examiner reliability of sagittal cervical alignment variables compared to the reliability and concurrent validity of computer vision algorithms used in the PostureRay® software 2024. Methods: A retrospective database of 254 lateral cervical radiographs of patients between the ages of 11 and 86 is studied. The radiographs include clearly visualized C1-C7 vertebrae that were evaluated by a human using the software. To evaluate examiner reliability and the concurrent validity of the trained CNN performance, two blinded trials of radiographic digitization were performed by an extensively trained expert user (US) clinician with a two-week interval between trials. Then, the same clinician used the trained CNN twice to reproduce the same measures within a 2-week interval on the same 254 radiographs. Measured variables included segmental angles as relative rotation angles (RRA) C1-C7, Cobb angles C2-C7, relative segmental translations (RT) C1-C7, anterior translation C2-C7, and absolute rotation angle (ARA) C2-C7. Data were remotely extracted from the examiner's PostureRay® system for data collection and sorted based on gender and stratification of degenerative changes. Reliability was assessed via intra-class correlations (ICC), root mean squared error (RMSE), and R2 values. Results: In comparing repeated measures of the CNN network to itself, perfect reliability was found for the ICC (1.0), RMSE (0), and R2 (1). The reliability of the trained expert US was in the excellent range for all variables, where 12/18 variables had ICCs ≥ 0.9 and 6/18 variables were 0.84 ≤ ICCs ≤ 0.89. Similarly, for the expert US, all R2 values were in the excellent range (R2 ≥ 0.7), and all RMSEs were small, being 0.42 ≤ RMSEs ≤ 3.27. Construct validity between the expert US and the CNN network was found to be in the excellent range with 18/18 ICCs in the excellent range (ICCs ≥ 0.8), 16/18 R2 values in the strong to excellent range (R2 ≥ 0.7), and 2/18 in the good to moderate range (R2 RT C6/C7 = 0.57 and R2 Cobb C6/C7 = 0.64. The RMSEs for expert US vs. the CNN network were small, being 0.37 ≤ RMSEs ≤ 2.89. Conclusions: A comparison of repeated measures within the computer vision CNN network and expert human found exceptional reliability and excellent construct validity when comparing the computer vision to the human observer.

Abnormal Static Sagittal Cervical Curvatures following Motor Vehicle Collisions: A Retrospective Case Series of 41 Patients before and after a Crash Exposure.

Previous investigations have found a correlation between abnormal curvatures and a variety of patient complaints such as cervical pain and disability. However, no study has shown that loss of the cervical curve is a direct result of exposure to a motor vehicle collision (MVC). This investigation presents a retrospective consecutive case series of patients with both a pre-injury cervical lateral radiograph (CLR) and a post-injury CLR after exposure to an MVC. Computer analysis of digitized vertebral body corners on CLRs was performed to investigate the possible alterations in the geometric alignment of the sagittal cervical curve. METHODS: Three spine clinic records were reviewed over a 2-year period, looking for patients where both an initial lateral cervical X-ray and an examination were performed prior to the patient being exposed to a MVC; afterwards, an additional exam and radiographic analysis were obtained. A total of 41 patients met the inclusion criteria. Examination records of pain intensity on numerical pain rating scores (NPRS) and neck disability index (NDI), if available, were analyzed. The CLRs were digitized and modeled in the sagittal plane using curve fitting and the least squares error approach. Radiographic variables included total cervical curve (ARA C2-C7), Chamberlain's line to horizontal (skull flexion), horizontal translation of C2 relative to C7, segmental translations (retrolisthesis and anterolisthesis), and circular modelling radii. RESULTS: There were 15 males and 26 females with an age range of 8-65 years. Most participants were drivers (28) involved in rear-end impacts (30). The pre-injury NPRS was 2.7 while the post injury was 5.0; p < 0.001. The NDI was available on 24/41 (58.5%) patients and increased after the MVC from 15.7% to 32.8%, p < 0.001. An altered cervical curvature was identified following exposure to MVC, characterized by an increase in the mean radius of curvature (265.5 vs. 555.5, p < 0.001) and an approximate 8° reduction of lordosis from C2-C7; p < 0.001. The mid-cervical spine (C3-C5) showed the greatest curve reduction with an averaged localized mild kyphosis at these levels. Four participants (10%) developed segmental translations that were just below the threshold of instability, segmental translations < 3.5 mm. CONCLUSIONS: The post-exposure MVC cervical curvature was characterized by an increase in radius of curvature, an approximate 8° reduction in C2-C7 lordosis, a mild kyphosis of the mid-cervical spine, and a slight increase in anterior translation of C2-C7 sagittal balance. The modelling result indicates that the post-MVC cervical sagittal alignment approximates a second-order buckling alignment, indicating a significant alteration in curve geometry. Future biomechanics experiments and clinical investigations are needed to confirm these findings.

Positive Outcomes Following Cervical Acceleration-Deceleration (CAD) Injury Using Chiropractic BioPhysics® Methods: A Pre-Auto Injury and Post-Auto Injury Case Series.

This series illustrates how rear-end impact motor vehicle collisions (MVCs) alter the cervical spine's alignment and demonstrates therapeutic use of cervical extension traction to improve lordotic alignment and other outcomes. This is a retrospective reporting of 7 adult patients (4 males and 3 females, 28-42 years) treated for cervical hypolordosis. These subjects received Chiropractic BioPhysics® (CBP®) rehabilitation and then were involved in a rear-end MVC. All cases had radiographic assessment that quantified the buckling of the cervical spine, presumably resulting directly from the CAD trauma. After an average of 3 years and 9 months (range: 1-7.6 years) following their initial program of care, the 7 patients sought care for a second time after the MVC. At this time, compared with their previously recorded post-treatment spine radiographs, there was an average 18.7° (range: 7.6-35.4°) reduction in cervical lordosis, a 9.2 mm (range: 3.6-19.8 mm) increase in anterior head translation (AHT), an 11.3° (range: 0.2-19.9°) decrease in the atlas plane line (APL), as well as a 35.7% (range: 22-52%) average neck disability index score (NDI) measured after the MVC. After the crash, a second round of CBP rehabilitation was administered, resulting in an average 15.1° improvement in cervical lordosis, 10.9 mm reduction in AHT, 10.4° increase in APL, and a 23.7% drop in NDI after an average of 35 treatments over 9 weeks. Treatment was universally successful, as an average 80% re-establishment of the lordosis toward its pre-injury state was found. There were no adverse events reported. This case series demonstrates that motor vehicle collisions may alter the alignment of the cervical spine. Rehabilitation of the cervical curve using extension traction improved the patients' initial pre-crash alignments toward their pre-injury alignments and was likely responsible for improvement in the patients' conditions. Clinical trials are needed to confirm these findings.

Subjective and Objective Improvement in a 39-Year-Old Male Suffering From Severe Chronic Pain and Disability Using Chiropractic BioPhysics® Protocols Following Rear-Impact Motor Vehicle Crash With a 10-Month Long-Term Follow-Up.

We present the case of a patient receiving structural rehabilitation following a rear-impact motor vehicle collision (MVC). Medications did not alleviate the symptoms of the crash injuries. Resolution of injury-caused pain and disability was found following postural and structural rehabilitation treatment. A 39-year-old male was injured in a rear-impact collision between two very large vehicles. Severe migraine headaches, neck pain, and radiculopathy, as well as lower back pain, were the result of the crash. Patient-reported outcomes (PROs) demonstrated that the symptoms were causing severe disability and poor health-related quality of life (HRQoL) measures. Radiographs found spine alignment abnormalities consistent with rear impact MVC. Chiropractic Biophysics® (CBP®) structural rehabilitation was performed. Following a treatment regimen involving strengthening weakened and damaged muscles, postural and spinal traction, postural spinal manipulative therapy (SMT), and home therapies resulted in the resolution of the symptoms. All outcome measures demonstrated improvement, including Short-Form 36 question health questionnaire (SF-36), quadruple visual analog scale (QVAS), headache disability index (HDI), neck disability index (NDI), revised Oswestry disability index (RODI), as well as significant measured improvements found on radiographs. Spine pain and altered alignment are frequent results of MVCs. If left uncorrected, these abnormalities increase the likelihood of chronic pain and disability. Combined low back pain (LBP), neck pain (NP), headache (HA), and radiculopathy, as found in our subject, significantly pre-dispose the individual to poor HRQoL, years lived with disability (YLDs) and increased the global burden of disease (GBD). Physicians who treat injured patients should have a repeatable, reliable, valid, and efficacious method to reduce pain, increase range of motion (ROM), improve spine alignment, and improve the performance of activities of daily living (ADLs). Further, larger studies of injured patients are necessary to determine if the CBP® protocol reduces GBD caused by MVC injuries.

The Subjective and Objective Improvement Using Chiropractic Biophysics® Protocols.

The aim of this study is to describe the Chiropractic BioPhysics® (CBP®) (Chiropractic BioPhysics, Eagle, USA) technique in alleviating the persistent spine pain syndrome (PSPS) and dysfunction in a 50-year-old female who suffered for many years. The purpose of this study is to provide clinicians with a potential treatment option for failed back surgery syndrome (FBSS) and PSPS that doesn't respond to other treatments. The patient did not receive benefits from pharmaceutical and conservative therapies following a low back lifting injury in 2004. After several years of suffering from widespread spinal pain and dysfunction, she received a lumbosacral pedicle screw surgical fixation. The initial surgery was unsuccessful and a follow-up revision and expansion of the fusion failed to alleviate the pain and dysfunction as well. After treatment using CBP, the patient received subjective, objective, and radiographic improvements with long-term stability measured at follow-up. Given that spine pain and low back pain are the number one cause of disability in the world, having economical, repeatable, and measurable techniques to improve even difficult cases is important for astute clinicians treating spine pain.

Conservative treatment of a patient with syringomyelia using chiropractic biophysics protocols.

OBJECTIVE: To present a case of a 41-year-old man with syringomyelia and intractable pain and the subsequent reduction of symptoms. CLINICAL FEATURES: This patient acquired a traumatically induced syrinx in his upper cervical spinal cord after he fell approximately 9 feet and landed on his head, upper back, and neck 9 years before presenting for care. He was diagnosed with a spinal cord cyst (syrinx), located at approximately C2 through C4 after magnetic resonance imaging. In 1995, the patient underwent occipitoatlantal decompression surgery, which improved his symptoms for a short time. INTERVENTION AND OUTCOMES: The patient was treated using Clinical Biomechanics of Posture protocol. The patient was seen 26 times over the course of 3 weeks. His scale for pain severity decreased 50% and other subjective complaints decreased. His posture improved based upon pretreatment and posttreatment lateral cervical radiographs, showing a change from a 10 degrees lordosis with midcervical kyphosis to a 30 degrees lordosis. One-year follow-up examination showed stable improvement in the cervical lordosis and pain intensity. CONCLUSION: This case represents a change in subjective and objective measurements after conservative chiropractic care. This case provides an example that structural rehabilitation may have a positive effect on symptoms of a patient with syringomyelia.

Sagittal skin contour of the cervical spine: interexaminer and intraexaminer reliability of the flexicurve instrument.

OBJECTIVES: To evaluate reliability of a simple instrument, the flexicurve, in determining cervical sagittal skin contour. METHODS: This study obtained repeated random measurements involving 3 investigators and 30 subjects once per day over a 2-day trial period. Thirty normal subjects were examined for cervical spine skin contour twice by 3 separate investigators with a 1-day delay. With subjects in a neutral standing position, investigators placed the flexicurve on the posterior portion of the subject's neck from the external occipital protuberance to the vertebral prominens and traced the flexicurve shape onto paper. The tracings were divided into 6 equal arcs and digitized. Statistical computation was performed on the depth at 5 points, arc angle, and arc radius of curvature. Interexaminer and intraexaminer correlation coefficients (ICCs) were calculated to determine reliability. RESULTS: All interexaminer correlation coefficients were in the poor range (<0.40). For the arc radius, arc angle, depth at top one third, and depth at bottom two thirds, the intraexaminer correlation coefficients were in the poor range. For the 3 deepest depths, the intraexaminer correlation coefficients were in the fair range (0.4-0.50). CONCLUSION: The flexicurve showed marginal reliability with most (12/16) ICCs in the poor range (ICC <0.40) and 4 values in the fair range (0.4 < ICC < 0.5).

Concurrent validity of flexicurve instrument measurements: sagittal skin contour of the cervical spine compared with lateral cervical radiographic measurements.

OBJECTIVES: The aim of this study was to compare flexicurve surface contour measurements of the cervical spine with radiographic measurements of cervical lordosis. METHODS: One examiner evaluated 96 patients with chronic neck pain in neutral posture using a flexible ruler, flexicurve, to measure sagittal contour of the skin over the cervical spine from the external occipital protuberance to the vertebra prominens. The flexicurve skin contour and neutral lateral radiographs were digitized and compared. The flexicurve and radiographs were categorized into height-length ratio, curve angle, curve depth, sum of depths, modified Ishihara's index, and inverse of radius. Mean values, SDs, mean differences, and limits of agreement were calculated. The differences between flexicurve measurement mean values and x-ray mean values were deemed significant if the lower limit of agreement exceeded 15% of the mean values for the x-ray measurements. RESULTS: For all variables, except the height-length ratio, the mean values of the flexicurve variables differed significantly from the corresponding mean values of the radiographic measurements. All Pearson correlation coefficients were in the very poor range (r < 0.15). CONCLUSION: The flexicurve sagittal skin contour measurement has poor concurrent validity compared with established radiographic measurements of the cervical lordosis. The flexicurve tracings always predicted lordosis, overestimated the lordosis compared with x-ray values, and cannot discriminate between radiographic lordosis, straightened, S curves, and kyphotic alignments of the cervical curve.

Cervical kyphosis is a possible link to attention-deficit/hyperactivity disorder.

OBJECTIVE: To discuss the case of a patient who was diagnosed with attention-deficit/hyperactivity disorder (ADHD) by a general practitioner and was treated with chiropractic care. CLINICAL FEATURES: A 5-year-old patient was diagnosed with ADHD and treated by a pediatrician unsuccessfully with methylphenidate (Ritalin), Adderall, and Haldol for 3 years. The patient received 35 chiropractic treatments during the course of 8 weeks. A change from a 12 degrees C2-7 kyphosis to a 32 degrees C2-7 lordosis was observed after treatment. During chiropractic care, the child's facial tics resolved and his behavior vastly improved. After 27 chiropractic visits, the child's pediatrician stated that the child no longer exhibited symptoms of ADHD. The changes in structure and function may be related to the correction of cervical kyphosis. CONCLUSION: The patient experienced significant reduction in symptoms. Additionally, the medical doctor concluded that the reduction in symptoms was significant enough to discontinue the medication. There may be a possible connection that correction of cervical kyphosis in patients with ADHD may produce a desirable clinical outcome.

Radiographic pseudoscoliosis in healthy male subjects following voluntary lateral translation (side glide) of the thoracic spine.

OBJECTIVE: To determine projected Cobb angles associated with trunk list (side shift) posture, hypothesizing that the side shift "scoliotic" curvature would be similar to true scoliotic curvature in the early stages. DESIGN: Anteroposterior (AP) radiographs of volunteers in neutral, in left, and right lateral translations of the thoracic cage (trunk list) were digitized. SETTING: Computer laboratory. PARTICIPANTS: Fifteen healthy male volunteers. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Cobb and Risser-Ferguson angles determined from digitizing vertebral body corners from T12 to L5 on 51 AP lumbar radiographs. RESULTS: Using the horizontal displacement of T12 from S1, subjects could translate an average of 54.0 mm to the left and 52.5 mm to the right. The average digitized Cobb T12-L5 angle produced for the 30 translated postures was 16 degrees. Angles ranged from 2.6 degrees to 27.0 degrees. Risser-Ferguson angles averaged 10 degrees between T12 and L5. Statistical correlations were found between Cobb L1-5 and translation to the left (P=.015), Cobb T12-L5 and translation to the right (P=.024), Risser-Ferguson angle and translation to the left (P=.021), and the lumbosacral angle to the right and trunk translation to the right (P=.027). CONCLUSIONS: During lateral translation of the thorax (trunk list), coupled lumbar lateral flexion resulted in the appearance of a pseudoscoliosis on AP radiographs. For this trunk list posture, Cobb angles are considerable (16 degrees ) and increase as the magnitude of trunk translation increases. Differentiating true structural scoliosis from this pseudoscoliosis would be clinically important. The small coupled axial rotation in trunk list is in contrast to the considerable degree of axial rotation observed in structural idiopathic scoliosis.

Evidence-based protocol for structural rehabilitation of the spine and posture: review of clinical biomechanics of posture (CBP) publications.

BACKGROUND: Although practice protocols exist for SMT and functional rehabilitation, no practice protocols exist for structural rehabilitation. Traditional chiropractic practice guidelines have been limited to acute and chronic pain treatment, with limited inclusion of functional and exclusion of structural rehabilitation procedures. OBJECTIVE: (1) To derive an evidence-based practice protocol for structural rehabilitation from publications on Clinical Biomechanics of Posture (CBP((R))) methods, and (2) to compare the evidence for Diversified, SMT, and CBP((R)). METHODS: Clinical control trials utilizing CBP(R) methods and spinal manipulative therapy (SMT) were obtained from searches in Mantis, CINAHL, and Index Medicus. Using data from SMT review articles, evidence for Diversified Technique (as taught in chiropractic colleges), SMT, and CBP((R)) were rated and compared. RESULTS: From the evidence from Clinical Control Trials on SMT and CBP((R)), there is very little evidence support for Diversified (our rating = 18), as taught in chiropractic colleges, for the treatment of pain subjects, while CBP((R)) (our rating = 46) and SMT for neck pain (rating = 58) and low back pain (our rating = 202) have evidence-based support. CONCLUSIONS: While CBP((R)) Technique has approximately as much evidence-based support as SMT for neck pain, CBP((R)) has more evidence to support its methods than the Diversified technique taught in chiropractic colleges, but not as much as SMT for low back pain. The evolution of chiropractic specialization has occurred, and doctors providing structural-based chiropractic care require protocol guidelines for patient quality assurance and standardization. A structural rehabilitation protocol was developed based on evidence from CBP((R)) publications.
