The evaluation of hand function after spinal cord injury (SCI) is conducted in clinical settings, which may not accurately reflect hand function in the real world, thereby limiting the efficacy assessment of new treatments. Wearable cameras, also known as egocentric video, are a novel method to evaluate hand function in non-clinical environments. Nonetheless, manual processing of vast quantities of complex video data is difficult, highlighting the need for automated data analysis. The objective of this study was to automatically identify distinct hand postures in egocentric video using unsupervised machine learning. Seventeen participants with cervical SCI recorded activities of daily living in a home simulation laboratory. A hand pose estimation algorithm was applied on detected hands to determine 2D joint locations, which were lifted to 3D coordinates. The resulting hand posture information was subjected to a number of clustering techniques. Hand grasps were manually labelled into four categories for evaluation purposes: power, precision, intermediate, and non-prehensile. K-Means clustering consistently exhibited the highest Silhouette score, which reflects the presence of discrete clusters in the data. When comparing with manual annotations, Spectral Clustering applied to a feature space consisting of 2D pose estimation with confidence scores yield the best performance as quantified by maximum match (0.48), Fowlkes-Mallows score (0.46), and normalized mutual information (0.22). This is the first attempt to develop an unsupervised, data-driven hand taxonomy for individuals with SCI using wearable technology. The findings suggest that the method is capable of grouping similar hand grasps.

Hamilton’s Spinal Cord Injury (SCI) Regional Rehabilitation Program in collaboration with SCI Consortium is implementing tissue integrity monitoring for pressure injury (PI) prevention. An increased prevalence of PI was found in 2021 - 2022 compared to 2020 on Hamilton’s SCI Rehabilitation Unit. To address this finding, the clinical team introduced a staff and patient education program focused on PI prevention. Upon completion of this workshop, the attendees will be aware of the CQI methodology used to implement the best practices related to tissue integrity and appreciate the education pathway for both staff and patients. Using a Continuous Quality Improvement model, a systematic approach was used to enhance the education model for staff and patients on skin assessment and appropriate interventions. A process map was created outlining steps for each discipline involved in skin assessment, intervention, and patient education. Education plan included Skin & Wound Management workshop, individual and group patient education, daily skin check calendar for patient/staff use. The workshop will be delivered in a lecture format, ending with discussion time. Preliminary data post partial implementation of the education program showed a decrease of 12% in the prevalence of PIs in the patients discharged from the program between July 2022 and March 2023 compared to January 2021 – June 2022. Preliminary results are encouraging in demonstrating that implementation of a comprehensive education plan for staff and patients using a structured framework is effective in reducing the prevalence of pressure injuries in the inpatient SCI rehab unit.

Participants of this workshop will be able to identify and recommend multimodal treatment options in managing challenging cases in spasticity management of lower limbs in spinal cord injury (SCI). The complexities of spasticity management will be identified through case-based presentations, including assessment and treatment directed by patient-oriented goals. Facilitated interactive discussion on these cases will engage participants for input, debate and critique. Procedural techniques for neurolysis will be discussed. Goals of spasticity management in SCI often include both proximal and distal lower limb problems. Therapies include oral medications, chemodenervation with neuromuscular junction blockade with botulinum toxin or neurolysis with phenol, intrathecal baclofen, bracing, and surgery. Many patients require multiple of these therapeutic options during their course of spasticity management. Multimodal therapy as part of the clinician toolbox is essential in tone management. Patient-oriented goals are important guideposts in spasticity management. SCI is a lifespan condition, and often patient goals and health conditions change over the years, requiring different tools to address such longitudinal needs.

Individuals with an incomplete spinal cord injury (iSCI) have increased risk of falls during walking and standing. Our previous longitudinal pilot study demonstrated that a therapeutic system (FES+VFT system) using functional electrical stimulation (FES) and visual feedback training (VFT) improved the standing balance of individuals with iSCI. This study investigated the orthotic and acute therapeutic effects of FES in the FES+VFT system. Fifteen individuals with iSCI will be recruited for this study. To date, four participants have completed the study. The four participants completed three different sessions. In the first session, participants were evaluated for their balance, postural control and familiarized with the FES+VFT system. In the second and third sessions, the participant completed training sessions with the FES+VFT system with or without FES. Centre of pressure (COP) data were collected via force platforms. Before and after the training, the motor evoked potentials (MEP) of the soleus and tibialis anterior muscles were recorded. There was a greater increase in the total dynamic range of the COP with FES+VFT than VFT (Anterior posterior: increase of 17.5 ± 14.27mm, medial lateral: increase of 17.9 ± 19.45mm). Both the soleus and tibialis anterior muscles showed greater increases in MEP after FES+VFT than VFT (Soleus: 70.4 ± 31.1% vs 5.45 ± 29.1%; Tibialis Anterior: 115.3 ± 234.8% vs 11.0 ± 42.9%). These findings suggest that FES improves the performance of VFT (positive orthotic effect) and increases the corticospinal connection (positive acute therapeutic effect) in individuals with iSCI.

Individuals with neurological injury or disease are at increased risk of experiencing falls, highlighting the need for effective balance interventions. A novel system integrating functional electrical stimulation and visual feedback balance training (FES+VFBT) is a promising balance intervention; however, this lab-based system requires a redesign to increase clinical utility. To identify possible challenges and solutions to implementing the FES+VFBT system as a balance intervention, from the perspective of end users. This qualitative study involved three semi-structured focus group meetings to explore participants’ perspectives on the feasibility and potential challenges of implementing FES+VFBT in neurorehabilitation. Two individuals with spinal cord injury (SCI), one individual with stroke, two physiotherapists and one hospital administrator participated. Interview transcripts were analyzed using a deductive-inductive content analysis. The levels of the Social Ecological Model (SEM) were used as themes for the deductive analysis. Categories and codes were detected using an inductive approach. The themes spanned the four levels of the SEM: intrapersonal, interpersonal, organizational/training environment and society/policy. Identified categories consisted of possible challenges mapped to the intrapersonal (e.g., lack of knowledge, tolerance of user) and organizational/training environment (e.g., cost, need for space and time, technical challenges) levels. Categories also reflected possible solutions mapped to all SEM levels: intrapersonal (e.g., reading and research), interpersonal (e.g., practicing together), organizational/training environment (e.g., tailoring system parameters, social support), and society/policy (e.g., create guidelines, provide cost options). The findings will be used to improve the FES+VFBT system design and facilitate implementation of the intervention in neurorehabilitation.
患有神经系统损伤或疾病的人发生跌倒的风险会增加，因此需要采取有效的平衡干预措施。集功能性电刺激和视觉反馈平衡训练（FES+VFBT）于一体的新型系统是一种很有前景的平衡干预措施；然而，这种基于实验室的系统需要重新设计，以提高临床实用性。 从最终用户的角度出发，找出实施功能性电刺激和视觉反馈平衡训练系统作为平衡干预措施可能面临的挑战和解决方案。 这项定性研究包括三次半结构化焦点小组会议，以探讨参与者对在神经康复中实施 FES+VFBT 的可行性和潜在挑战的看法。两名脊髓损伤（SCI）患者、一名中风患者、两名物理治疗师和一名医院管理人员参加了会议。访谈记录采用演绎-归纳内容分析法进行分析。社会生态模型 (SEM) 的层次被用作演绎分析的主题。使用归纳法确定类别和代码。 这些主题跨越了 SEM 的四个层次：个人、人际、组织/培训环境和社会/政策。确定的类别包括人际（如缺乏知识、用户容忍度）和组织/培训环境（如成本、空间和时间需求、技术挑战）层面可能存在的挑战。分类还反映了映射到所有 SEM 层次的可能解决方案：个人（如阅读和研究）、人际（如共同练习）、组织/培训环境（如定制系统参数、社会支持）和社会/政策（如制定指南、提供成本选择）。 研究结果将用于改进 FES+VFBT 系统设计，促进神经康复干预措施的实施。

Persons with lived experience of SCI (PLEX) living in rural areas have difficulty accessing optimal care and are required to travel long distances to access specialized services. Clinicians not affiliated with specialized urban centres recognize that developing knowledge and skills specific to SCI will improve care outcomes. Praxis has conducted multiple workshops on SCI topics throughout the BC Interior Health Region to improve clinician knowledge about SCI. Topics include pressure injuries, autonomic dysreflexia, specialized equipment, bowel and bladder, etc. Utilizing evidence-based information and PLEX experiences, these workshops have increased clinician confidence when working with clients with SCI. This interactive workshop explores the development and implementation of the sessions, from the perspectives of a clinician, a PLEX, and a knowledge exchange expert. The goals of this workshop are to: This workshop demonstrates the benefit of SCI knowledge exchange for clinicians working in rural areas. Furthermore, it highlights key factors in developing these workshops, and provides an opportunity to connect with other rural SCI initiatives and networks aimed at enhancing the care and well-being of PLEX.

We studied the feasibility of a home-based screening sleep test (HBSST), the validity of four questionnaires used to screen for sleep-related breathing disorders (SRBDs), and the potential association between SRBD and clinical features in individuals with spinal cord injury (SCI). Adults with subacute/chronic (>1 month post-injury) SCI were recruited for the cross-sectional study and qualitative analysis. Feasibility of the HBSST was objectively evaluated and participants shared their experience. We also examined the validity of the Berlin, STOP, Medical Outcomes Study Sleep Scale [MOS-SS], and STOP-Bang screening questionnaires. We investigated the association between the degree of SRBD and three features (i.e., neck circumference, body mass index [BMI] and oropharynx opening as assessed using the Modified Mallampati classification [MMC]). There were 13 females and 18 males with ages varying from 20 to 86 years (mean age: 54.7 years) with motor complete (n=8) or incomplete SCI at cervical (n=21) or thoraco-lumbar levels. Time since SCI varied from 1.5 to 474 months. Overall, 28 individuals completed the HBSST and endorsed its feasibility. Mean apnea-hypopnea index (AHI) was 17.3 events/hour (range: 0.5-83.7). AHI was significantly correlated with Berlin (p=0.036) and STOP-Bang scores (p=0.009). There was no significant correlation between AHI and MOS-SS (p=0.348) or STOP (p=0.165). AHI was not associated with neck circumference (p=0.614), BMI (p=0.958), or MMC (p=0.335). Our results suggest that HBSST is a feasible screening method, and Berlin and STOP-Bang are valid screening questionnaires for the SCI population. AHI was not correlated with BMI, neck circumference, or MMC.

Heart disease is the most common cause of death after spinal cord injury or disease (SCI/D), with Cardiometabolic Disease (CMD) risk a primary contributor. 1) To report the frequency of Physical Activity guideline adherence; 2) To report the frequency of serum lipid screening recall and their recollection of the result interpretation; among adults living with SCI/D in the community. A Kinesiologist collected the SCI-High outcome data via in person or phone 1:1 interviews, and chart abstraction among UHN outpatients. A Provincial Intake Coordinator collected data via phone interview among outpatients affiliated with SCI Ontario. Survey responses were scored using Reachlite’s optical character recognition software. Descriptive statistics characterize the participant’s age, sex, impairment characteristics, and adherence to physical activity guidelines and the frequency of lipid screening/interpretation recall. Best practice education materials were used to increase future PA guideline adherence, prompt lipid screening, and healthy food choices. Adult outpatients (n=127, 67% male), mean age 61 years, and 55% paraplegic consented to participate. In total, 48% (60/126) of outpatients reported engaging in some form of aerobic exercise; of whom 50% (30/60) of these individuals were meeting current PA guidelines. About 51% of outpatients recalled lipid screening within the last year, 33% indicated they had not had an assessment. Clinical interpretation of lipid values was recalled by 71% (53/75) of outpatients. Physical activity guideline adherence and routine lipid assessments are integral to CMD risk modification – substantial education resources and recall aids may help to modify CMD risk after SCI/D.

Spinal cord injury (SCI) affects locomotion and quality of life. Two spinal cord stimulation approaches are currently under investigation for restoring standing and walking following SCI: epidural spinal cord stimulation (ESCS) and intraspinal microstimulation (ISMS). In ESCS, electrodes are placed on the dura mater and in ISMS, ultrafine wires are inserted into the cord. These modalities likely activate the locomotor regions in the ventral horn through different pathways. The goal of this study is to examine the difference in the distribution of neuronal activation and the type of neurons activated by ESCS and ISMS. The first step was to establish the needed immunohistochemical (IHC) staining protocols. Domestic pigs were divided into naïve (n=2) and positive control (n=1) groups. The naïve control animals were anesthetized for 5 hrs. The positive control animal was anesthetized for 2 hrs and injected with hypertonic saline in hindlimb muscles. The animals were then euthanized, and the spinal cord removed for IHC analysis. Antibodies against cFos, a maker of neuronal activation, and NeuN, a neuronal marker were used. Preliminary results indicate that ESCS activates neurons in the dorsal horn with scattered activation in the intermediate and ventral regions. ISMS primarily activates neurons in the intermediate and ventral regions where locomotor-related networks reside. To the best of our knowledge, this is the first time the type and sites of activation of ESCS and ISMS are investigated. This will provide a foundational understanding of the mechanism of action of these stimulation modalities.
