Abstract
Schistosomose mansoni is an endemic disease in Brazil. It rarely affects the central nervous system, particularly in children. We report the case of a child that presented with an acute spinal cord compression condition, resulting from a mass that proved to be a granuloma caused by a Schistosoma mansoni infection. Proper treatment had no effect on the regression of urological symptoms and the child had to undergo a Mitrofanoff principle.

Abstract
Context: Patient-reported outcome measures (PROMs) are valuable for capturing the impact of spasticity on health-related quality of life (HRQoL) in persons with spinal cord damage (SCD) and evaluating the efficacy of interventions. Objective: To provide practical guidance for measuring HRQoL in persons with spasticity following SCD. Methods: Literature reviews identified measures of HRQoL and caregiver burden, utilized in studies addressing spasticity in SCD. Identified measures were evaluated for clinical relevance and practicality for use in clinical practice and research. The PRISM, SCI-SET, EQ-5D and SF-36 instruments were mapped to the International Classification of Functioning, Disability and Health (ICF). The PRISM and SCI-SET were evaluated using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist. Results: Two spasticity-specific, five generic, and four preference-based measures were identified. ICF mapping and the COSMIN checklist supported the use of the PRISM and SCI-SET in SCD. The SF-36 is considered the most useful generic measure; disability-adapted versions may be more acceptable but further studies on psychometric properties are required. The SF-36 can be converted to a preference-based measure (SF-6D), or alternatively the EQ-5D can be used. While no measures specific to caregivers of people with SCD were identified, the Caregiver Burden Scale and the Zarit Burden Interview are considered suitable. Conclusion: Recommended measures include the PRISM and SCI-SET (condition-specific), SF-36 (generic), and Caregiver Burden Scale and Zarit Burden Interview (caregiver burden). Consideration should be given to using condition-specific and generic measures in combination; the PRISM or SCI-SET combined with SF-36 is recommended.

Abstract
Study Design Retrospective case series. Purpose This study aimed to examine the efficacy of composite grip strength as a marker of surgical outcome in patients with moderate to severe degenerative cervical myelopathy. Overview of Literature Degenerative cervical myelopathy causes loss of dexterity, muscle strength, and sensations in the hand. The impact of surgical management on improvement in composite grip strength has received scant attention. Methods This retrospective study was performed on degenerative cervical myelopathy patients with a complete composite grip strength assessment between January 2013 to January 2019. The Biometrics E-link hand kit was used for the assessment. The following parameters were measured: maximum grip strength, sustained grip strength, three-jaw pinch, maximum key pinch, and sustained key pinch. The pre- and postoperative functional status was assessed using the Nurick grade and the modified Japanese Orthopaedic Association (mJOA) score. Results A total of 40 patients were included in the study. The mean patient age was 51.9 years. The mean preoperative Nurick grade was 3.5 and the mJOA score was 10.9. The anterior approach was used in 25 patients, and the posterior approach was used in 15 patients. Four patients developed complications. Degenerative cervical myelopathy resulted in decreased handgrip and pinch strength as compared to normative Indian data. There was a significant improvement in the postoperative composite grip strength for all five parameters. There was no differential improvement between the anterior and posterior surgical groups. The improvement in the composite grip strength correlated with the improvement in functional scores. Conclusions Composite grip strength analysis is an objective method for assessing the impact of degenerative cervical myelopathy on grip strength and monitoring the postoperative improvement. Decompressive surgery resulted in global improvement in all the parameters of composite grip strength.

Abstract
Spinal cord injury (SCI) is a severe neurological disease; however, there is no effective treatment for spinal cord injury. Neuroinflammation involves the activation of resident microglia and the infiltration of macrophages is the major pathogenesis of SCI secondary injury and considered to be the therapeutic target of SCI. Parthenolide (PN) has been reported to exert anti-inflammatory effects in fever, migraines, arthritis, and superficial inflammation; however, the role of PN in SCI therapeutics has not been clarified. In this study, we showed that PN could improve the functional recovery of spinal cord in mice as revealed by increased BMS scores and decreased cavity of spinal cord injury in vivo. Immunofluorescence staining experiments confirmed that PN could promote axonal regeneration, increase myelin reconstitution, reduce chondroitin sulfate formation, inhibit scar hyperplasia, suppress the activation of A1 neurotoxic reactive astrocytes and facilitate shift from M1 to M2 polarization of microglia/macrophages. To verify how PN exerts its effects on microglia/macrophages polarization, we performed the mechanism study in vitro in microglia cell line BV-2. PN could significantly reduce M1 polarization in BV2 cells and partially rescue the decrease in the expression of M2 phenotype markers of microglia/macrophage induced by LPS, but no significant effect on M2 polarization stimulated with IL-4 was observed. Further study demonstrated PN inhibited NF-κB signal pathway directly or indirectly, and suppressed activation of signal transducer and activator of transcription 1 or 3 (STAT1/3) via reducing the expression of HDAC1 and subsequently increasing the levels of STAT1/3 acetylation. Overall, our study illustrated that PN may be a promising strategy for traumatic SCI.

Delayed quadriparesis after posterior spinal fusion for scoliosis: a case series. Spine Deform 2020; 8:1075-1080. [PMID: 32274769 DOI: 10.1007/s43390-020-00113-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Accepted: 03/29/2020] [Indexed: 10/24/2022]
Abstract
STUDY DESIGN A multicenter retrospective IRB exempt case series analyzing clinical and radiographical data of patients treated by three surgeons over the past two decades was conducted. OBJECTIVE To examine the factors involved in the development of quadriparesis in patients who underwent posterior spinal fusion for scoliosis. Delayed spinal cord infarcts usually present at the region of instrumentation according to reports from the Scoliosis Research Society. Nonetheless, there is a lack of data regarding factors associated with delayed quadriparesis following posterior spinal fusion METHODS: Evaluated variables were age, Cobb angle, blood loss, and curve correction percentage. Postoperative imaging was also evaluated to determine factors indicative of the etiology of the quadriparesis. RESULTS Eight patients presented delayed postoperative quadriparesis. All patients had a postoperative examination equal to that of baseline. The first patient deteriorated at 6 h postoperatively and the most delayed patient presented 4 days postoperatively. Six patients had neuromuscular disorders and 2 had adolescent idiopathic scoliosis. Mean age was 13.7, mean curve magnitude was 78.7°, mean percent curve correction was 71% and the mean estimated blood loss was 1185 cc. Seven of eight patients had documented peri- or postoperative hypotension. CONCLUSIONS Cervical infarction is the likely cause of delayed quadriparesis after posterior spinal fusion. Even though the underlying etiology continues to be unclear, postoperative hypotension, curve magnitude, percent curve correction, and the presence of cervical kyphosis/stenosis may be contributory and need to be closely evaluated.

Abstract
The authors present a case of acute disseminated encephalomyelitis in a COVID-19 pediatric patient with positive SARS-CoV2 markers from a nasopharyngeal swab. A previously healthy 12-year-old-girl presented with a skin rash, headache, and fever. Five days after that, she had an acute, progressive, bilateral, and symmetrical motor weakness. She evolved to respiratory failure. Magnetic resonance imaging (MRI) of the brain and cervical spine showed extensive bilateral and symmetric restricted diffusion involving the subcortical and deep white matter, a focal hyperintense T2/FLAIR lesion in the splenium of the corpus callosum with restricted diffusion, and extensive cervical myelopathy involving both white and gray matter. Follow-up examinations of the brain and spine were performed 30 days after the first MRI examination. The images of the brain demonstrated mild dilatation of the lateral ventricles and widespread widening of the cerebral sulci, complete resolution of the extensive white matter restricted diffusion, and complete resolution of the restricted diffusion in the lesion of the splenium of the corpus callosum, leaving behind a small gliotic focus. The follow-up examination of the spine demonstrated nearly complete resolution of the extensive signal changes in the spinal cord, leaving behind scattered signal changes in keeping with gliosis. She evolved with partial clinical and neurological improvement and was subsequently discharged.

Abstract
OBJECTIVES To evaluate the incidence and epidemiologic characteristics of acquired nontraumatic spinal cord injury (NTSCI) in Finland. DESIGN Prospective 4-year epidemiologic multicenter study. SETTING Two of the 3 spinal cord injury (SCI) centers in Finland responsible for acute care, immediate rehabilitation, and lifelong follow-up for all SCI patients in a population of 3,073,052 (as of 2013). PARTICIPANTS All newly diagnosed NTSCI patients (N=430) admitted to Tampere University Hospital between 2012 and 2015 and Oulu University Hospital between 2013 and 2016 based on the evaluation of the designated rehabilitation teams. Patients with NTSCI resulting from congenital etiologies or progressive neurologic diseases were excluded. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Incidence and variables, according to the International SCI Core Data Set and the International Standards for Neurological Classification of SCI, including etiology and the severity of injury. RESULTS The incidence of NTSCI was 54.1 per million per year. NTSCI was more common in men (n=260, 60.5%) than women (n=170, 39.5%). The mean age was 62.0±14.6 years old. Degenerative causes were the most common etiology (n=219, 50.9%), followed by malignant (n=88, 20.5%) and benign (n=41, 9.5%) neoplasms. The injury resulted in tetraplegia in 177 patients (41.1%) and paraplegia in 249 patients (57.9%). American Spinal Injury Association Impairment Scale grade D injuries were common, with an incidence of 71% (n=304). Specialized inpatient rehabilitation was needed in 44% (n=189) of the cases. CONCLUSIONS There are no previous studies on the epidemiology of NTSCI in Finland, and international reporting has been limited. The incidence of NTSCI in our study was substantially higher than in most previous studies, which was likely owing to our study including individuals with less severe lesions who did not require inpatient rehabilitation.

Abstract
Objectives: There are few studies of sexual abuse in people with spinal cord damage (SCD). Objective of this study was to determine the prevalence and impact of sexual abuse in SCD. Design: Survey (web and paper-based). Setting: Australia (August 2013-June 2014). Participants: People with SCD (n = 136); able-bodied controls (n = 220). Interventions: None. Outcome measures: Spinal Cord Injury Secondary Conditions Scale, International SCI Quality of Life Basic Dataset, and the Physical Disability Sexual and Body Esteem scale. Questions regarding demographic and clinical characteristics, sex, sexual orientation, relationship status, disability, sexual interest and satisfaction, and sexual abuse. Results: Most SCD participants were male (n = 92, 67%), the average age was 46 years (SD = 14) and they were median of 11 years (IQR 4-21) after SCD. Of these, 19% (n = 26) reported sexual abuse. Females were much more likely to report being abused (odds ratio 3.3, 95%CI 1.5-7.4; χ2=10.9, P = 0.001). Participants reporting sexual abuse were younger (P = 0.01) and more likely to have been abused before their SCD (69%). There was no significant difference between those with SCD who reported sexual abuse and those who did not regarding their quality of life as a whole (P > 0.1). There was no difference regarding the reporting of sexual abuse between able-bodied and those with SCD (P = 0.1). Conclusion: Sexual abuse was relatively common and was not associated with an adverse relationship with the covariates assessed. Further research is needed to better determine the prevalence of sexual abuse in people with SCD and its impact.

Abstract
Syringomyelia is a rare disorder in which a fluid-filled cyst forms within the spinal cord, resulting in myelopathy. Meanwhile, the abnormal dilatation of the central canal is referred to as hydromyelia or slit-like syrinx. The most prevailing classification is based on anatomical features and pathogeny rather than pathophysiological mechanisms. It is usual to distinguish foraminal syringomyelia related mainly to abnormalities at the craniocervical junction, non-foraminal syringomyelia dealing with any cause of arachnoiditis (infection, inflammation, trauma…) and more rarely syringomyelia associated with intramedullary tumors. Although many pathophysiological theories have been argued over time, the prevailing one is that disturbances in cerebrospinal fluid (CSF) flow in the sub-arachnoid spaces disrupt flow velocity leading to the syrinx. Symptoms of paralysis, sensory loss and chronic pain commonly develop during the third/fourth decades of life. The natural history of syringomyelia is typically one of gradual, stepwise neurological deterioration extending over many years. Diagnosis is based on magnetic resonance imaging (MRI) including excellent morphological sequences (T1-, T2-, FLAIR-, T2*-, enhanced T1-) and dynamic MRI with careful study of CSF velocity (CISS, cine-MR sequences). Surgical management is at first dedicated to treat the cause of the syringomyelia, mainly to re-establish a physiological CSF pathway in the subarachnoid spaces. Mostly, the surgical goal is to enlarge the craniocervical junction with duraplasty. Other surgical strategies such as arachnoidolysis or shunt procedures are performed based on the pathogenic mechanisms or as second-line treatment. Medical treatments are also necessary as chronic pain is the main long-lasting symptom. As evolutive syringomyelia is a severe disease with a high impact on quality of life, it is recommended to treat without delay. There is no evidence for surgery for incidental asymptomatic syringomyelia or hydromyelia. Finally, syringomyelia associated with intramedullary tumors resolves spontaneously after tumor resection. Syringomyelia is a rare disease, which requires a dedicated multidisciplinary approach, emphasizing the need for a nationwide scientific organization so as to offer optimal care to the patient.

Abstract
PURPOSE Posterior cervical expansive open-door laminoplasty (LAMP) is a mature surgical procedure for the treatment of cervical spondylotic myelopathy (CSM), but there are few studies on the changes in cervical sagittal balance. This study aimed to analyze the imaging and clinical data of patients who underwent LAMP and to explore the effect of this procedure on the cervical sagittal balance. METHODS This was a retrospective study of the patients who underwent LAMP between 01/2014 and 12/2017. The C0-C2 Cobb angle, sagittal vertical angle (SVA), C2-C7 Cobb angle, and T1-slope were measured. The Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), and visual analog scale (VAS) were used. RESULTS There were 69 males and 39 females. The mean age was 61.3 ± 5.3 years. The C0-C2 Cobb angle increased from 11.3 ± 5.5° to 26.8 ± 4.8° (P = 0.186). The C2-C7 Cobb angle decreased from 13.9 ± 8.6° to 10.65 ± 10.7° P = 0.016). SVA increased from 21.0 ± 5.8 mm to 25.4 ± 11.5 mm (P = 0.001). The preoperative average JOA score was 11.1 ± 2.2 points, and the postoperative score was 14.0 ± 2.1 points, with an average improvement rate of JOA of 46.5 ± 3.8%. The NDI score decreased from preoperative 15.6 ± 5.4 points to 11.3 ± 7.9 points, and the VAS score was decreased from 4.6 ± 1.8 points to 3.3 ± 1.6 points (all P < 0.05). CONCLUSION LAMP improved the neurological function and quality of life of patients with CSM. The cervical vertebrae show a tendency of tilting forward, suggesting that overextension of the upper cervical vertebra might be used to maintain the center of gravity of the skull and horizontal vision.

Abstract
[Purpose] To evaluate the severity of symptoms before and after cervical myelopathy
surgery using the Simple Test for Evaluating hand Function. Because a test ceiling effect
was observed in patients with less severe forms of myelopathy, we investigated the
correlation between and accuracy of several different tests in order to clarify the
usefulness of the Purdue Pegboard Test for evaluation of one or both hands. [Participants
and Methods] Thirty-four patients (6 females and 28 males; mean age, 64.5 years) were
examined, and scores were determined for each of the following tests: Purdue Pegboard
Test; Simple Test for Evaluating hand Function; Japanese Orthopedic Association
assessment; and Disabilities of the Arm, Shoulder, and Hand assessment. Correlations
between scores of different tests were then determined. The cut-off values used for the
Purdue Pegboard Test and the Simple Test for Evaluating hand Function were determined
using the area under the receiver operating characteristic curve to assess the use of
chopsticks. [Results] The Purdue Pegboard Test assembly task correlated moderately with
the Japanese Orthopedic Association and Disabilities of the Arm, Shoulder, and Hand
scores. In the receiver operating characteristic curve analyses, the Purdue Pegboard Test
cut-off value was 11 and the Simple Test for Evaluating hand Function cut-off value was
90. [Conclusion] The Purdue Pegboard Test is useful for evaluating manual dexterity and
coordination in both hands in patients with cervical myelopathy.

Abstract
The examination of sacral reflexes provides an important method to differentiate an upper motor neuron vs lower motor neuron spinal cord injury (SCI). Two common sacral mediated reflexes used as part of the neurological assessment include the bulbocavernosus reflex (BCR) and anal reflex. As the clinical information from these tests are similar, we suggest that the anal reflex provides a better first option as a non-invasive clinical assessment of sacral reflex status in clinical practice in SCI as the testing for the anal reflex is less intrusive and already being performed as part of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) by pinprick stimulation of the S4-5 dermatome.

Abstract
Study design Cross-sectional study. Objectives To measure and expand the sitting workspace of participants with spinal cord injury (SCI) with the Trunk-Support-Trainer (TruST). Setting Columbia University. Methods TruST is a motorized-cable belt placed around the torso. Participants performed maximal trunk excursions along eight directions, radiating in a star-shape, to define their seated postural limits and workspace area (cm2). TruST was configured to apply "assist-as-needed" forces when the trunk moved beyond these postural limits. Kinematics were collected to examine trunk control. The clinical features of the sample (n = 5) were documented by neurological injury, dynamometry, the American Spinal Injury Association Impairment Scale, and Spinal Cord Independence Measure-III. Results Statistical significance was examined with paired t-tests. TruST successfully recreated the postural limits of participants and expanded their active sitting workspace (Mean: 123.3 ± SE: 42.8 cm2, p < 0.05). Furthermore, participants improved their trunk excursions to posterior (Mean: 5.1 ± SE: 0.8 cm, p < 0.01), right (Mean: 3.1 ± SE: 1.1 cm, p < 0.05), and left (Mean: 5.0 ± SE: 1.7 cm, p = 0.05) directions with TruST-force field. Conclusions TruST can accurately define and expand the active seated workspace of people with SCI during volitional trunk movements. The capacity of TruST to deliver continuous force-feedback at the user's postural limits opens new frontiers to implement motor learning-based paradigms to retrain functional sitting in people with SCI.

Abstract
The 2018 Guideline for the Identification and Management of Cardiometabolic Risk after Spinal Cord Injury (SCI) represented the first concerted effort to address a cluster of derangements and diseases that are claiming the lives of individuals living with injuries. Its contributors and authors scoured the literature, weighed the validity, importance, and clinical relevance of what data they found, and collaborated in an effort to meaningfully improve the health and lives of people with SCI. However, we are concerned that several of the guideline's central recommendations-particularly around screening for and detection of glycemic dysregulation and dyslipidemia-have been offered prematurely. In several instances, the authors cite data from studies of people without SCI and, in our opinion, inappropriately apply those findings to support their SCI-specific suggestions. In other instances, they recommend that we employ tests whose usefulness and clinical relevance have yet to be demonstrated among people living with injuries. In short, we fear that the authors have developed clinical guidelines that are inadequately supported by data. This guideline is an extraordinary show of collaboration, and is an important first step toward understanding and treating a number of secondary cardiometabolic effects of SCI. The lack of data underpinning several of its central recommendations-making them, in our opinion, unadoptable-underscores the inadequacy of research in this area and provides a roadmap for future investigative efforts.

Abstract
This perspective advocates for the adoption of recently published clinical practice guidelines on identifying and managing cardiometabolic risk after spinal cord injury (SCI). It makes the case for acting now, with the knowledge that we currently have, while continuing to address knowledge gaps with high-quality research studies in this area. Cardiovascular disease is a leading cause of death in people with SCI. Cardiometabolic disease (CMD) and risks are more likely to be overlooked after SCI. Unique SCI-related considerations impact both assessment and management of cardiometabolic risk. Risk factors and components of CMD including obesity, impaired glucose tolerance/insulin resistance, dyslipidemia, and hypertension should be evaluated and managed to optimize the cardiometabolic health of this population. While it would be optimal to base all care on high-quality evidence-based research, its absence should not be an excuse for inaction. Applying what is currently known and filling the research gaps with empirical recommendations based on clinical rationale and expert consensus is both appropriate and necessary till more definitive SCI-specific evidence becomes available.

Repecki C, Sliwinski M, Harding L. Supporting the need for community exercise programs: a case study. Spinal Cord Ser Cases 2019; 5:95. [PMID: 31798970 PMCID: PMC6877531 DOI: 10.1038/s41394-019-0236-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Revised: 09/03/2019] [Accepted: 10/11/2019] [Indexed: 11/08/2022] Open
Abstract
Introduction Participation in exercise activities post spinal cord injury (SCI) can positively impact physical functioning and quality of life. Physically active individuals have improved functional performance compared with sedentary individuals with SCI. Consistent exercise interventions following SCI not only prompt neural recovery and offer myriad health benefits but they may also have persisting effects on functional abilities. Case presentation A 29-year-old male subject had a 15-year history of a C5-C6 AIS B SCI. The subject demonstrated improvements in the outcome measures and he reported enhanced ability to cough and to clear secretions, as well as an enhanced overall quality of life, after undergoing a 14-week course of Spinal Mobility training in combination with inspiratory muscle training (IMT). In addition to the Spinal Mobility training and IMT, he continued to partake in his normal exercise routine, which consisted of aerobic and strength training 3 days per week. Discussion This case reaffirms the benefits of consistent exercise training, in combination with IMT, for individuals with SCI. Community programs specifically targeted to individuals with SCI are needed. The subject's functional improvements demonstrate that incorporating Spinal Mobility training into a regular exercise routine may assist with functional gains in the chronic stage of SCI.

Abstract
Introduction The human T-lymphotropic virus has been associated with human disease, affecting CD4+ T, CD8+ T, and B lymphocytes. It can cause T-cell leukemia/lymphoma and HTLV-associated myelopathy. Case presentation A 31-year-old woman was admitted after 2 months of cramps, paraparesis, and fecal/urinary incontinence. She was diagnosed with neurosyphilis according to the cerebrospinal fluid analysis. Despite treatment with crystalline penicillin there was no recovery, and anti-HTLV-1/2 tests were positive; therefore, the diagnosis of HTLV-associated myelopathy was made. The patient rejected glucocorticoid treatment; baclofen and carbamazepine were used to treat spasticity and cramps, respectively. The patient has not had progression. Discussion HTLV-associated myelopathy is generated by an exaggerated inflammatory response in the central nervous system with clonal expansion of CD4+ T and CD8+ T lymphocytes. There is not a specific and useful treatment; glucocorticoids can reduce inflammation, but do not improve clinical functional outcomes. There is a high prevalence of syphilis and human T-lymphotropic virus co-infection in tropical countries; however, myelopathy as the first clinical manifestation is unusual. The treatment of neurosyphilis could reduce the inflammation into the central nervous system and could decrease the progression of sequelae. This is the first case of myelopathy secondary to viral and treponemal co-infection confirmed in Colombia.

Abstract
Study design Retrospective review of data. Objective To determine if there is a relationship between the Asia Impairment Scale (AIS) and the bladder and bowel components of the International Standards to Document Remaining Autonomic Function after SCI (ISAFSCI). Setting University-Based Academic Rehabilitation Program. Methods Retrospective cross-sectional study assessing International Standards for Neurologic Classification After SCI (ISNCSCI) examination along with bladder and bowel components of the ISAFSCI. Results Subjects with AIS A injuries were statistically less likely to have history of bladder control and bowel control per investigator determination and bladder sensation via self-report versus patients categorized with AIS B injuries. Self-reported history of bowel sensation and control of voiding were more likely in subjects with C, D, or E injuries than with B injuries. Bowel and bladder control as determined by investigator and bladder and bowel sensation and control as self-reported were all statistically less likely in persons with AIS A injuries versus CDE. Conclusions This retrospective study provides initial data regarding components of the bladder and bowel sections of the sacral ISAFSCI and AIS. Further prospective research is needed to further characterize the relationship between retention of bladder and bowel sensation and function and the AIS. We suggest that incorporation of the sacral components of the ISAFSCI into the ISNCSCI may be beneficial to obtain further information about retention of sacral function with specific patterns of injury.

Abstract
Study design Case series. Objectives This case series describes how the aquatic environment influences gait initiation in terms of the center of pressure (COP) excursion, impulses, trunk acceleration, and perceptions of participants with incomplete spinal cord injury (iSCI). Setting Tertiary Rehabilitation Hospital, Ontario, Canada. Methods Five individuals with iSCI (four cervical injuries/one thoracic injury, AIS D) participated in the study. Baseline clinical balance was evaluated by Berg Balance Scale and Mini-Balance Evaluation System Test. Participants initiated gait on a waterproof force plate and walked ~4 steps, in water and on land. COP trajectories during anticipatory and execution phases, impulses, and trunk acceleration parameters were investigated. Perceptions of walking in both environments were obtained using an interview. Results COP trajectory was prominently longer when individuals stepped forward. A decrease in velocity of COP was observed predominantly in the AP direction during stepping. Non-normalized vertical impulses decreased as the AP impulses increased, in water compared to land. Upper to lower trunk acceleration ratios showed how water resistance influenced the lower trunk acceleration. Most of participants reported that walking in water was challenging, but safer than on land. Conclusions Participants with higher balance function seemed to have more pronounced changes in anticipatory and execution phases' duration, length and velocity of COP. A faster anticipatory phase and a slower execution phase were observed in water than on land. Participants walked in water using a different trunk control strategy than on land and reported no fear of falling when walking in water versus land.

Abstract
BACKGROUND Three-dimensional gait analysis (3DGA) has not previously been considered by consensus panels of spinal cord experts for use in studies of patients with spinal cord damage (SCD), yet it is frequently used in other neurological populations, such as stroke and cerebral palsy. RESEARCH QUESTION How does 3DGA impairment based reporting guide individualised clinical decision-making in people with incomplete SCD? METHODS Retrospective open cohort case series recruited 48 adults with incomplete SCD (traumatic or non-traumatic spinal cord dysfunction) referred to the Clinical Gait Analysis Service (CGAS), Melbourne, Australia. Three-dimensional gait data were used to identify gait impairments by the multidisciplinary clinical team. Gait patterns were classified using the plantarflexor-knee extension couple index and the Gait Profile Score (GPS). The reason for referral and the recommendations made post-3DGA were collated in decision trees to extrapolate the potential value of 3DGA in decision making for targeted intervention in this population. RESULTS Participants with SCD generally walked at a reduced gait speed. When grouped by neurological level, the tetraplegia group had a significantly lower GPS, but no specific gait patterns emerged. Participants were primarily referred to the CGAS to direct clinical intervention decisions. The most frequent recommendation following 3DGA was the prescription of an ankle foot orthosis and in some cases, the recommendation was incongruent with the referrer's proposed intervention. SIGNIFICANCE 3DGA can provide specific guidance in management plans for gait of patients with incomplete SCD and may help to avoid inappropriate or unnecessary interventions. This sample of patients referred to the CGAS demonstrates its clinical utility in guiding clinicians in their decision making to target individualised intervention.

Abstract
Urtication and flagellation were used as a last resort in the treatment of paralysis when all other means were exhausted, and very few cases are reported in the literature. Two cases were identified and reviewed, one of urtication (flogging with nettles) and one of flagellation (beating with rods). In both cases the symptoms were alleviated, but there was insufficient detail to evaluate the therapeutic value of each treatment.

Abstract
Study design Pre-post, pilot study. Objectives To characterize ventilatory (VE) responses to exercise following warm-up walking in individuals with chronic incomplete spinal cord injury (iSCI) during constant work rate (CWR) exercise. Secondarily, to investigate VE and tidal volume (VT) variability, and ratings of perceived exertion (RPE) before and after overground locomotor training (OLT). Setting Research laboratory. Methods A 6-min CWR walking bout at preferred pace was used as a warm-up followed by 6 min of rest and a second 6-min CWR bout at above preferred walking pace. The second CWR bout was analyzed. Breath-by-breath ventilatory data were examined using a curvilinear least squares fitting procedure with a mono-exponential model. VE and VT variability was calculated as the difference between the observed and predicted values and RPE was taken every 2 min. Results Participants (n = 3, C4-C5) achieved a hyperpneic response to exercise in VE and VT. OLT resulted in faster ventilatory kinetics and reductions of 24 and 29% for VE and VT variability, respectively. A 30% reduction in RPE was concurrent with the reductions in ventilatory variability. Conclusions OLT may improve ventilatory control during CWR in patients with cervical motor-iSCI. These data suggest that in some participants with iSCI, ventilation may influence RPE during walking. Future research should investigate mechanisms of ventilatory variability and its implications in walking performance in patients with iSCI.

Abstract
Study design Randomized, double-blinded, placebo-controlled, cross-over study. Objective To explore whether botulinum toxin A (BoNTA) could be effective for treating at-level spinal cord injury (SCI) pain. Setting Outpatient SCI clinic, New York, USA. Methods Participants were randomized to receive subcutaneous injections of either placebo or BoNTA with follow-up (office visit, telephone, or e-mail) at 2, 4, 8, and 12 weeks to assess the magnitude of pain relief post injection. Crossover of participants was then performed. Those who received placebo received BoNTA, and vice versa, with follow-up at 2, 4, 8, and 12 weeks. Results Eight participants completed at least one of the two crossover study arms. Four completed both arms. The median age of the eight participants was 45 years (range 32-61 years) and 75% were male. All had traumatic, T1-L3 level, complete SCI. Although our data did not meet statistical significance, we noted a higher proportion of participants reporting a marked change in average pain intensity from baseline to 8 and 12 weeks post-BoNTA vs. post-placebo (33% vs. 0%). At 2 and 4 weeks post-BoNTA, almost all participants reported some degree of reduced pain, while the same was not seen post-placebo (83% vs. 0%). Conclusion The subcutaneous injection of BoNTA may be a feasible approach for the control of at-level SCI pain and is worthy of further study. Sponsorship The onabotulinumtoxinA (BOTOX) used in this study was provided by Allergan (Irvine, CA).

Abstract
Hirayama disease, a juvenile muscular atrophy of the distal upper extremity, is a rare form of cervical flexion myelopathy characterized by insidiously progressive weakness of the hands and forearm muscles (i.e., painless amyotrophy). The pathognomonic finding is a markedly forward-shifted spinal cord during neck flexion, demonstrated by dynamic magnetic resonance imaging (MRI), as in a young man with muscle atrophy in the bilateral distal upper extremities. In this report, the authors describe a 31-year-old man who had the classic radiological and clinical presentations of Hirayama disease. Since prior medical treatment had been ineffective for years, he underwent multilevel instrumented anterior cervical discectomy and fusion (ACDF) to keep his subaxial cervical spine slightly-lordotic (nonflexion). His motor evoked potential amplitude improved immediately during the operation, and there were improvements of myelopathy and a modest reversal of muscle wasting at 1 year postoperatively. Postoperative dynamic cervical spine MRI also demonstrated minimal cord compression and elimination of the venous plexus engorgement dorsal to the thecal sac. Although Hirayama disease is benign in nature and frequently self-limiting, multilevel instrumented ACDF could be a reasonable management option.

Abstract
Introduction Postprandial hypotension (PPH) is a postmeal drop in systolic blood pressure that may or may not be symptomatic. While the etiologies of PPH are incompletely understood, it is thought to occur when glucose absorption causes increased splanchnic blood flow or "pooling" in people who lack sufficient compensatory responses to support their systemic blood pressure. Postprandial hypotension is well described in individuals with neurodegenerative diseases, yet only rarely in people living with spinal cord injury (SCI). Acarbose is an alpha-glucosidase inhibitor that treats PPH by slowing gastric transit time and reducing glucose uptake in the small intestine, hence decreasing superior mesenteric artery blood flow. Case presentation A 62-year-old woman with long-standing cervical SCI presented with 5 years of worsening postprandial lightheadedness, visual "flashes", and neck pain. She had had multiple episodes of near and frank syncope and her prior medical team had initiated midodrine three times daily. We began treatment with acarbose, starting at 50 mg with each meal and rapidly titrating to 100 mg at mealtime. She noticed an immediate improvement in her symptoms and an attenuation of postmeal drops in both systolic and diastolic blood pressures. Discussion To our knowledge, this is one of the first described cases of PPH among people living with SCI. Given the autonomic dysfunction that frequently accompanies higher-level of injuries, it is possible that many more people with SCI have this condition, whether or not it is symptomatic. Acarbose is one of the several established treatments for PPH, and proved effective and tolerable for our patient.
