Surgical Technique: Brachioradialis to Extensor Carpi Radialis Longus and Brevis Nerve Transfers for Tetraplegia.

Improving upper extremity function in high cervical spinal cord injury (SCI) patients with tetraplegia is a challenging task owing to the limited expendable donor muscles and nerves that are available. Restoring active wrist extension for these patients is critical because it allows for tenodesis grasp. This is classically achieved with brachioradialis (BR) to extensor carpi radialis brevis (ECRB) tendon transfer, but outcomes are suboptimal because BR excursion is insufficient and its origin proximal to the elbow further limits the functionality of the tendon transfer, particularly in the absence of elbow extension. As an alternative approach to restore wrist extension in patients with ICSHT group 1 SCI, we present the first clinical report of the BR to extensor carpi radialis longus (ECRL) and BR to ECRB nerve transfers.

The presence of Candida parapsilosis with intrathecal baclofen pump in a person with high cervical spinal cord injury; infection or colonization? A Case Report

IntroductionIntrathecal baclofen (ITB) therapy is an effective method of treating spasticity in persons with spasticity due to spinal cord injury (SCI), but complications are not rare and can include spinal fluid leaks, infection, and catheter/pump malfunction.Case presentationThis study presents information related to an adult male patient with traumatic SCI and a history of two prior ITB pump pocket infections that required removal due to pump infection. The patient then developed skin erosion over the third pump, and the fluid around the pump grew methicillin-sensitive Staphylococcus aureus, diphtheroids, and Candida parapsilosis. The patient was initially treated with antibiotics and anti-fungal medication without removal of the ITB pump. The ITB pump was eventually removed 27 months later, and the fourth pump was implanted 10 months later.DiscussionITB pumps can be an effective treatment modality for spasticity in people with SCI; however, complications, including infection, can occur and require pump removal. This case illustrates a case of possible Candida colonization of the ITB pump, which was eventually removed.

Abstract 18832: Early Leadless Pacemaker Implantation in a Case of Severe Cervical Spinal Cord Injury

Introduction: Bradycardia is a frequent cause of morbidity and mortality in spinal cord injury (SCI) patients and optimal timing of permanent pacemaker implant is unclear. Case Summary: A 67-year-old female with no cardiac history was admitted for fall of uncertain etiology complicated by severe cervical SCI and neurogenic shock. Despite emergent surgical decompression, the injury resulted in quadriplegia. Post-operatively, bradycardic arrest occurred requiring resuscitation and dependence on dopamine infusion. Rhythm strip from showed p-p slowing followed by high grade atrioventricular block with multiple blocked p waves. A decision was made for early intervention with implantation of a Micra leadless pacemaker (LPM) (Medtronic, Minneapolis, MN) for both hemodynamically significant bradycardia and backup to prevent bradycardic arrest. A LPM was successfully implanted without complication on hospital day 8. The pacemaker was set to VVI 60. Post operatively, the patient required intermittent pacing and tolerated dopamine weaning. Discussion: Bradycardia in SCI patients, especially those with high cervical and complete SCI, occurs due to unopposed parasympathetic activity, resulting in baseline sinus bradycardia. Even more concerning is the risk for sudden and unpredictable sinus arrest and/or AV block, which is a leading cause of mortality in the first year after SCI. While initial management of bradyarrhythmia in SCI patients may respond to pharmacologic intervention, temporary and/or permanent pacing may be indicated. Acute SCI patients may not be ideal candidates for traditional pacemakers since ICU and infectious complications are common in this cohort, but LPMs have extremely low risk of implant site and infectious complications and can be utilized earlier in the hospital course. Our case showcases this strategy of early leadless pacemaker implantation. Further study is needed to better evaluate the safety and efficacy of this strategy.

Closed-loop cervical epidural stimulation partially restores ipsilesional diaphragm EMG after acute C2 hemisection

Cervical spinal cord injury creates lasting respiratory deficits which can require mechanical ventilation long-term. We have shown that closed-loop epidural stimulation (CL-ES) elicits respiratory plasticity in the form of increased phrenic network excitability (Malone et. al., E Neuro, Vol 9, 0426–21.2021, 2022); however, the ability of this treatment to create functional benefits for breathing function per se after injury has not been demonstrated. Here, we demonstrate in C2 hemisected anesthetized rats, a 20-minute bout of CL-ES administered at current amplitudes below the motor threshold restores paralyzed hemidiaphragm activity in-phase with breathing while potentiating contralesional activity. While this acute bout of stimulation did not elicit the increased network excitability seen in our chronic model, a subset of stimulated animals continued spontaneous ipsilesional diaphragm activity for several seconds after stopping stimulation. These results support the use of CL-ES as a therapeutic to rescue breathing after high cervical spinal cord injury, with the potential to lead to lasting recovery and device independence.

Association of upper-limb neurological recovery with functional outcomes in high cervical spinal cord injury.

High cervical spinal cord injury (SCI) results in complete loss of upper-limb function, resulting in debilitating tetraplegia and permanent disability. Spontaneous motor recovery occurs to varying degrees in some patients, particularly in the 1st year postinjury. However, the impact of this upper-limb motor recovery on long-term functional outcomes remains unknown. The objective of this study was to characterize the impact of upper-limb motor recovery on the degree of long-term functional outcomes in order to inform priorities for research interventions that restore upper-limb function in patients with high cervical SCI. A prospective cohort of high cervical SCI (C1-4) patients with American Spinal Injury Association Impairment Scale (AIS) grade A-D injury and enrolled in the Spinal Cord Injury Model Systems Database was included. Baseline neurological examinations and functional independence measures (FIMs) in feeding, bladder management, and transfers (bed/wheelchair/chair) were evaluated. Independence was defined as score ≥ 4 in each of the FIM domains at 1-year follow-up. At 1-year follow-up, functional independence was compared among patients who gained recovery (motor grade ≥ 3) in elbow flexors (C5), wrist extensors (C6), elbow extensors (C7), and finger flexors (C8). Multivariable logistic regression evaluated the impact of motor recovery on functional independence in feeding, bladder management, and transfers. Between 1992 and 2016, 405 high cervical SCI patients were included. At baseline, 97% of patients had impaired upper-limb function with total dependence in eating, bladder management, and transfers. At 1 year of follow-up, the largest proportion of patients who gained independence in eating, bladder management, and transfers had recovery in finger flexion (C8) and wrist extension (C6). Elbow flexion (C5) recovery had the lowest translation to functional independence. Patients who achieved elbow extension (C7) were able to transfer independently. On multivariable analysis, patients who gained elbow extension (C7) and finger flexion (C8) were 11 times more likely to gain functional independence (OR 11, 95% CI 2.8-47, p < 0.001) and patients who gained wrist extension (C6) were 7 times more likely to gain functional independence (OR 7.1, 95% CI 1.2-56, p = 0.04). Older age (≥ 60 years) and motor complete SCI (AIS grade A-B) reduced the likelihood of gaining independence. After high cervical SCI, patients who gained elbow extension (C7) and finger flexion (C8) had significantly greater independence in feeding, bladder management, and transfers than those with recovery in elbow flexion (C5) and wrist extension (C6). Recovery of elbow extension (C7) also increased the capability for independent transfers. This information can be used to set patient expectations and prioritize interventions that restore these upper-limb functions in patients with high cervical SCI.

146 Functional Priorities in High Cervical Spinal Cord Injury: Implications for Upper Limb Nerve Transfer Surgery

INTRODUCTION: High cervical spinal cord injury (SCI) results in complete impairment in upper limb function. Nerve transfer is an innovative reinnervation strategy for upper limb reanimation following SCI. However, the impact of upper limb motor recovery on the degree of long-term functional outcomes remains unknown. METHODS: A prospective cohort of high cervical SCI (C1-C4) patients enrolled in SCI model systems (SCIMS) was included. Baseline neurological examinations and functional independence measures (FIM) in eating, bladder-function, and transfers (bed/wheelchair/chair) were evaluated. At one-year follow-up, functional independence was compared in patients who gained recovery (motor grade &gt;=3) in C5-elbow flexion, C6-wrist extension, C7-elbow extension, and C8-finger flexion. A multivariable logistic regression evaluated the impact of motor recovery on functional independence on composite outcome of feeding, bladder-function, and transfers. RESULTS: Between 1992-2016, 405 high cervical SCI patients were included. At baseline, 97% patients had impaired upper limb function with inability in all functions. At one-year follow-up, the largest proportion of patients gaining independence in eating, bladder-function, and transfers had recovery in C8-finger-flexion and C6-wrist-extension. C5-elbow-flexion recovery had lowest translation into functional independence. Patients who achieved C7-elbow-extension were able to transfer independently. On multivariable analysis, C8-finger-flexion recovery had 12-times higher odds (p=0.004) and C6-wrist-extension recovery had 7-times higher odds (p=0.04) of gaining functional independence in composite outcome. Age &gt;=60 years and motor complete SCI (ASIA-A-B) were associated with reduced odds of gaining independence. 8% patients improved ASIA grades from baseline to 1-year. CONCLUSIONS: Following cervical SCI, C8-finger-flexion and C6-wrist-extension recovery can maximize functional independence. Recovery of C7-elbow-extension can increase transfer capability. This information may prioritize reinnervation strategies for individualized decision-making for nerve transfers in high cervical SCI.

Cervical spinal cord injury leads to injury and altered metabolism in the lungs.

High-cervical spinal cord injury often disrupts respiratory motor pathways and disables breathing in the affected population. Moreover, cervically injured individuals are at risk for developing acute lung injury, which predicts substantial mortality rates. While the correlation between acute lung injury and spinal cord injury has been found in the clinical setting, the field lacks an animal model to interrogate the fundamental biology of this relationship. To begin to address this gap in knowledge, we performed an experimental cervical spinal cord injury (N = 18) alongside sham injury (N = 3) and naïve animals (N = 15) to assess lung injury in adult rats. We demonstrate that animals display some early signs of lung injury two weeks post-spinal cord injury. While no obvious histological signs of injury were observed, the spinal cord injured cohort displayed significant signs of metabolic dysregulation in multiple pathways that include amino acid metabolism, lipid metabolism, and N-linked glycosylation. Collectively, we establish for the first time a model of lung injury after spinal cord injury at an acute time point that can be used to monitor the progression of lung damage, as well as identify potential targets to ameliorate acute lung injury.

Paced breathing and respiratory movement responses evoked by bidirectional constant current stimulation in anesthetized rabbits.

Objective: Diaphragm pacing (DP) is a long-term and effective respiratory assist therapy for patients with central alveolar hypoventilation and high cervical spinal cord injury. The existing DP system has some limitations, especially high price, inconvenience preoperative evaluation methods and diaphragm fatigue easily. Our objective was to develop a DP system and evaluated reliability through hardware testing and animal experiments. Methods: A DP system with bidirectional constant current was designed, manufactured and tested. Effects of a wide range of stimulus amplitudes (range: .5-2.5mA) and frequencies (range: 10-250Hz) on airflow and corresponding inspired volume were investigated during DP. Differences in airflow characteristics under various stimulation parameters were evaluated using power function. ECG interference in diaphragm electromyography (EMGdi) was filtered out using stationary wavelet transform to obtain pure EMGdi (EMGdip). 80-min period with a tendency for diaphragm fatigue by root mean square (RMS) and centroid frequency (f c ) of EMGdip was studied. Results: The increase of stimulus frequency and amplitude in animals resulted in different degrees of increase in envoked volume. Significant difference in Airflow Index (b) between anesthesia and DP provided a simple, non-invasive and feasible solution for phrenic nerve conduction function test. Increased stimulation duration with the developed DP system caused less diaphragm fatigue. Conclusion: A modular, inexpensive and reliable DP was successfully developed. Its effectiveness was confirmed in animal experiments. Significance: This study is useful for design of future implantable diaphragmatic pacemakers for improving diaphragm fatigue and convenient assessment of respiratory activity in experiments.

Fourteen-year change in activities of daily living of a quadriplegic, ventilator-managed patient injured by high cervical spinal cord injury during infancy: a case report

BackgroundRehabilitation of patients with high cervical spinal cord injury (CSCI) to improve activities of daily living (ADL) is challenging due to severe paralysis. In addition, pediatric patients with CSCI are rare, and literature describing ADL changes as the patient grows are limited. In this case report, we present the long-term change in ADL over time in a girl with severe high CSCI from an injury during infancy.Case presentationA 2 years and 6 months old girl, who was injured in a traffic accident, was diagnosed with C3 CSCI, resulting in complete quadriplegia and respiratory paralysis below C3. Thus, she was managed with a ventilator. Rehabilitation for quadriplegia, respiratory dysfunction, and autonomic neuropathy was started on the fifth day after the injury while she was in the intensive care unit. Six months after the injury, the patient was transferred to a hospital. Thereafter, she was discharged with nursing and care guidance provided to her family and environmental changes at home. Afterwards, she continued to acquire skills through writing training using a mouse stick, computer operation training, and electric wheelchair operation training, which enabled her to improve her ADL despite her severe disability. In terms of education, she was able to go through a regular elementary school, a regular junior high school, and then to a senior high school of a support school.ConclusionsWe believe that training that utilizes current technology and changes in the environment that are appropriate for daily life are important for improving the ADL of children with severe CSCI.

A preliminary study on the feasibility of community game-based respiratory muscle training for individuals with high cervical spinal cord injury levels: a novel approach

BackgroundRespiratory disorders result in rehospitalization and premature death of patients with cervical spinal cord injuries (CSCI). Community game-based respiratory muscle training (RMT) programs could reduce secondary complications.MethodsWe examined the feasibility and preliminary efficacy of RMT as a community-based exercise program. Among the 10 included participants (eight male and two female), four, one, one, and four reported C3, C4, C5, and C6 complete injuries, respectively (eight graded by American Spinal Injury Association impairment scale [ASIA] A and two by ASIA B). Their mean age was 43 ± 12.3 y. The time since injury was 10 ± 6.7 y. The participants completed an RMT program for 60 min/day, twice weekly, for 8 weeks. The participants were trained in the use of a newly developed game-based RMT device. The device provides consistent pressure for respiratory muscle strength and endurance training. Seven RMT devices were modified to allow 10 game-based RMT programs. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), peak expiratory flow (PEF), vital capacity (VC), inspiratory capacity (IC), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and peak cough flow (PCF) were measured.ResultsThere were improvements after RMT compared to pre-RMT in FVC (p = 0.027, 10.62%, 0.22 effect size [ES]), PEF (p = 0.006, 23.21%, 0.45 ES), VC (p = 0.002, 35.52%, 0.60 ES), IC (p = 0.001, 46.94%, 0.81 ES), IRV (p = 0.001, 90.53%, 1.22 ES), MIP (p = 0.002, 97.25%, 1.32 ES), MEP (p = 0.005, 141.12%, 1.07 ES), and PCF (p = 0.001, 35.60%, 0.74 ES). The participants reported a positive impact of the program.ConclusionsCommunity game-based RMT for individuals with CSCI appears to be safe and feasible. Community exercise with RMT use may have a positive impact on the respiratory measures for patients with CSCI who are vulnerable to respiratory compromise.Trial registrationKCT0005980.

Effects of C2 hemisection on respiratory and cardiovascular functions in rats.

High cervical spinal cord injuries induce permanent neuromotor and autonomic deficits. These injuries impact both central respiratory and cardiovascular functions through modulation of the sympathetic nervous system. So far, cardiovascular studies have focused on models of complete contusion or transection at the lower cervical and thoracic levels and diaphragm activity evaluations using invasive methods. The present study aimed to evaluate the impact of C2 hemisection on different parameters representing vital functions (i.e., respiratory function, cardiovascular, and renal filtration parameters) at the moment of injury and 7 days post-injury in rats. No ventilatory parameters evaluated by plethysmography were impacted during quiet breathing after 7 days post-injury, whereas permanent diaphragm hemiplegia was observed by ultrasound and confirmed by diaphragmatic electromyography in anesthetized rats. Interestingly, the mean arterial pressure was reduced immediately after C2 hemisection, with complete compensation at 7 days post-injury. Renal filtration was unaffected at 7 days post-injury; however, remnant systolic dysfunction characterized by a reduced left ventricular ejection fraction persisted at 7 days post-injury. Taken together, these results demonstrated that following C2 hemisection, diaphragm activity and systolic function are impacted up to 7 days post-injury, whereas the respiratory and cardiovascular systems display vast adaptation to maintain ventilatory parameters and blood pressure homeostasis, with the latter likely sustained by the remaining descending sympathetic inputs spared by the initial injury. A better broad characterization of the physiopathology of high cervical spinal cord injuries covering a longer time period post-injury could be beneficial for understanding evaluations of putative therapeutics to further increase cardiorespiratory recovery.

Pulmonary rehabilitation in high cervical spinal cord injury: a series of 133 consecutive cases.

This is a retrospective study. To detail respiratory management after a high cervical spinal cord injury (HCSCI). A tertiary university hospital's pulmonary rehabilitation center to which most individuals with HCSCI and ventilatory insufficiency throughout Korea are referred. The medical records of individuals with complete or sensory incomplete HCSCI admitted to the pulmonary rehabilitation center and receiving the center's standard treatment were retrospectively reviewed, focusing on respiratory state transitions. In total, 133 individuals with a C1-4 neurological level of injury (A: 101 or B: 32 on the American Spinal Injury Association Impairment Scale) were identified; 110 (82.7%) had indwelling tracheostomy tubes at admission and 75 underwent successful decannulation during admission. At the final follow-up, 76 individuals (57.1%) still required mechanical ventilation (MV) and 37 (27.8%) still required indwelling tracheostomy tubes. Of the individuals who had tracheostomy tubes without ventilatory support, 30 underwent decannulation and were discharged without non-invasive MV support. Of those with MV via tracheostomy on admission, 25 were switched to non-invasive MV after decannulation. Respiratory management in complete or sensory incomplete HCSCI needs to be determined by reflecting the current ventilatory state with a comprehensive evaluation of pulmonary function and ventilatory state monitoring. Pulmonary rehabilitation in individuals with HCSCI should be emphasized in the aspect of improving quality of life by avoiding unwanted tracheostomy and changing management methods depending on their recovery.

Male Mice Expressing Human APOE4 Genotype Exhibit Greater Baseline Respiratory Rate and Less Robust Hypoxic Ventilatory Response Than APOE3 Mice as Measured by Whole Body Plethysmography

Breathing is vital for life and is both uniquely complex and vulnerable to disruption. Disorders of breathing such as those that occur in sleep apnea and even high cervical spinal cord injury (SCI) can impair quality of life and potentiate the ill effects of comorbidities like Alzheimer’s disease (AD). Indeed, studies have shown greater cognitive and cardiovascular impairments in subjects with sleep apnea and AD. Apolipoprotein E (ApoE) is a ubiquitous protein found throughout the body and CNS which aids in the regulation and transport of cholesterol and lipids. Moreover, the E4 allele confers a higher risk of early onset AD than either the E2 or E3 alleles. Previous research in our lab has shown the interaction between ApoE genotype and sex differentially affects breathing motor plasticity following SCI in mice. However, it is unknown how baseline respiratory pattern and capability during hypoxic challenge may differ between uninjured individuals expressing APOE4 and E3 alleles. Thus, with APOE genotype as our independent variable, we measured the respiratory parameters of male E3 and E4 targeted replacement mice using whole body plethysmography (WBP), hypothesizing that E3 animals would display a more adaptive, heightened response to hypoxic exposure than those expressing E4. Preliminary data comparing E3 animals (n=9) and E4 animals (n=8) demonstrated differences across several key measurements. At baseline, E4 animals were shown to breathe in an energy inefficient manner as exemplified high measures in tidal volume and frequency. During sustained hypoxia, frequency, tidal volume, and minute volume initially increased across all animals, but APOE3 animals mounted a much more robust and sustained response with APOE4 values falling well below baseline measures prior to termination of hypoxia. These preliminary results suggest a critical role of the APOE genotype in regulation of baseline breathing and in response to hypoxic conditions and that possessing the APOE4 allele may confer vulnerabilities in respiratory function and during environmental challenges leading to cognitive decline. Future directions include examining anatomically critical CNS respiratory regions and neural cell function.

Humanized ApoE4 Female Mice Exhibit a More Robust Hypoxic Ventilatory Response Than Female E3 Mice

Breathing is essential to life and can be easily disrupted by many adverse events. Disorders such as high cervical spinal cord injury (SCI) and sleep apnea can decrease quality of life and enhance the ill effects of comorbidities like Alzheimer’s disease (AD). Previous studies have shown an increase in cognitive impairments in subjects with both sleep apnea and AD. Apolipoprotein E (ApoE) is a protein found throughout the body and central nervous system (CNS) that is involved in the regulation and transport of cholesterol and lipids. Out of the three APOE human alleles (E2, E3, and E4), the E4 allele has been implicated in the early onset and higher risk of AD when compared to E2 or E3. Previous research in our lab has shown that the interaction between APOE genotype and sex has different effects on breathing motor plasticity following a cervical SCI in mice. However, it is unknown how baseline respiratory pattern and capability differs between uninjured individuals expressing either ApoE4 or E3, specifically under hypoxic conditions. Unpublished data from our lab has examined these differences in male mice, showing that E4 male mice have high variation in respiratory pattern, as well as a less robust response to hypoxia. Using ApoE as our independent variable, we measured respiratory parameters of female C57/BL6 ApoE3 and ApoE4 humanized mice using whole body plethysmography (WBP), hypothesizing that ApoE3 animals would display a greater baseline respiratory rate and have a more adaptive, heightened response to hypoxic exposure than those expressing ApoE4. Preliminary data comparing E3 female animals (n=8) and E4 female animals (n=8) showed differences across several key measurements. Interestingly, ApoE4 humanized female mice had a more robust response to hypoxic exposure that failed to persist following cessation of hypoxia. However, at baseline, E4 female animals showed no differences in respiratory pattern in contrast to our previously collected male ApoE4 data. These results indicate a critical role of the APOE genotype in the regulation of breathing and response to hypoxic conditions which differs between males and females. To further understand this distinction, future experiments will examine differences in levels of brainstem and spinal cord serotonin expression between ApoE3 and E4 males and females, as well as plasticity following injury in areas high in ApoE expression.

Autonomic Dysreflexia with Concurrent Orthostatic Hypotension: A Clinical Approach Dilemma

Background and aim: Autonomic dysreflexia (AD) commonly occurs in high cervical spinal cord injury (SCI) patients. However, concurrent orthostatic hypotension (OH) makes the management of this condition more difficult. This case report highlighted the complicated condition that creates a dilemma for clinicians to prioritise the management. Methods: A 26-year-old man presented with traumatic cervical SCI C4 ASIA B secondary to C3 – C5 vertebral body fracture underwent anterior corpectomy and fusion. He had frequent episodes of AD in the rehabilitation clinic, presenting with sweating, headache, and high blood pressure (BP) while he was in a wheelchair. No other precipitating factors were identified except for his chronic sacral and ischial wounds. These AD episodes also happened multiple times daily at home with intermittent presyncope attacks. He was given stat doses of Nifedipine during the clinic visits but was never prescribed antihypertensive as no proper BP monitoring was done at home. Nonpharmacological measures for OH were already established. The rehabilitation team educated him on a side-lying position to alleviate his AD symptoms and preventive strategies such as optimal pressure relief with wheelchair cushions and using the reclining function on his motorised wheelchair. Results: He had difficulty achieving independent mobility because he could not tolerate upright sitting without having AD and intermittent OH. Conclusion: OH as a precipitating factor for AD should be considered. The lowest possible dose of antispastic medications for optimum spasm control and consideration of mineralocorticoid drugs for OH management may be helpful. Antihypertensives are commonly used for prophylaxis of chronic recurrent AD. However, its usage may be limited in patients with OH. Prazosin may be an option as studies have shown that it did not excessively lower baseline BP. Pressure mapping and surgical intervention to facilitate chronic non-healing wound closure also should be considered. Chronic recurrent AD with intermittent OH remains a challenging condition in high SCI.

A Case of Incomplete Spinal Cord Injury Associated with Brown Sequard Syndrome After Cervical Blunt Trauma with Atlanto-Axial Rotatory Subluxation in a Paediatric Patient

Background and aim: Brown Sequard Syndrome (BSS) is a rare clinical presentation of incomplete spinal cord injury and even rarer caused by blunt trauma in the paediatric population. We presented a case of a paediatric patient with high cervical spinal cord injury due to blunt trauma resulting in atlantoaxial rotatory subluxation (AARS). Methods: A 10-year-old boy acquired SCI AIS D and neurological level of C4 due to AARS Fielding 1 secondary to blunt trauma. He had right extremities weakness with the majority of key muscle’s strength of MRC 2-3 and impaired sensory function under the neurological level for light touch and pinprick. The tactile impairment was more prominent on the right side with preserved proprioception, pain, and temperature sensation. Results: The patient underwent Gardner Well Tongs (GWT) traction procedure which was maintained for 2 weeks and then prescribed with Minerva Brace. He also showed signs of reflexive neurogenic bladder. The patient was hospitalised for 2 weeks in the rehabilitation ward for independence and intermittent catheterisation training. He ambulated using a wheelchair at the time of discharge but could walk independently using a quadripod cane after 1 month of follow-up, showing good motor recovery. Conclusion: Most cases of traumatic Brown Sequard usually arise from penetrating or stab wound, while blunt trauma is usually accompanied by spine fracture or non-bony elements such as ligament instability or subluxation. This patient only had AARS fielding 1, but the extensive right side motor weakness might be caused by a direct acceleration-deceleration mechanism at the cervical spinal cord followed by secondary trauma due to oedema and diminished blood perfusion. As a result, this patient did not show pure classic BSS in terms of sensory impairment but had hemiplegia. For pediatric patients, determining the prognosis and optimisation of appropriate rehabilitation programs for children is crucial for maximal outcomes and long-term quality of life.
