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.
我们研究了家庭筛查睡眠测试(HBSST)的可行性、用于筛查睡眠相关呼吸紊乱(SRBD)的四种问卷的有效性,以及脊髓损伤(SCI)患者的 SRBD 与临床特征之间的潜在关联。 这项横断面研究和定性分析招募了亚急性/慢性(受伤后超过 1 个月)SCI 患者。我们对 HBSST 的可行性进行了客观评估,参与者分享了他们的经验。我们还检查了柏林、STOP、医学结果研究睡眠量表 [MOS-SS] 和 STOP-Bang 筛查问卷的有效性。我们研究了SRBD程度与三个特征(即颈围、体重指数[BMI]和使用改良马兰帕蒂分类法[MMC]评估的口咽开放度)之间的关联。 患者中有 13 名女性和 18 名男性,年龄从 20 岁到 86 岁不等(平均年龄:54.7 岁),运动性完全(8 人)或不完全 SCI 位于颈椎(21 人)或胸腰椎水平。自 SCI 后的时间从 1.5 个月到 474 个月不等。共有 28 人完成了 HBSST,并认可其可行性。平均呼吸暂停-低通气指数 (AHI) 为 17.3 次/小时(范围:0.5-83.7)。AHI 与柏林评分(p=0.036)和 STOP-Bang 评分(p=0.009)明显相关。AHI 与 MOS-SS (p=0.348) 或 STOP (p=0.165) 之间无明显相关性。AHI 与颈围 (p=0.614)、体重指数 (p=0.958) 或 MMC (p=0.335) 无关。 我们的结果表明,HBSST 是一种可行的筛查方法,而柏林和 STOP-Bang 是 SCI 患者的有效筛查问卷。AHI 与体重指数、颈围或 MMC 无关。

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.
心脏病是脊髓损伤或脊髓疾病(SCI/D)后最常见的死亡原因,而心脏代谢疾病(CMD)风险是主要诱因。 1) 报告遵守体育锻炼指南的频率;2) 报告社区中患有脊髓损伤/疾病的成年人进行血清脂质筛查的频率及其对结果解释的回忆。 一名运动神经学家通过面对面或电话 1:1 访谈以及病历摘录的方式收集了 UHN 门诊病人的 SCI-High 结果数据。一名省接收协调员通过电话采访安大略省 SCI 附属门诊患者收集数据。使用 Reachlite 光学字符识别软件对调查回答进行评分。描述性统计描述了参与者的年龄、性别、损伤特征、对体育锻炼指导原则的遵守情况以及血脂筛查/解释回顾的频率。最佳实践教育材料用于提高未来对体育锻炼指南的依从性、及时进行血脂筛查和选择健康食品。 成年门诊患者(人数=127,67%为男性),平均年龄61岁,55%为截瘫患者,同意参加此次活动。总共有 48% (60/126)的门诊患者表示进行过某种形式的有氧运动;其中 50%(30/60)的人符合当前的运动量指南。约 51% 的门诊患者回忆起去年进行过血脂筛查,33% 的患者表示没有进行过评估。71%(53/75)的门诊患者回忆起血脂值的临床解释。 遵守体育锻炼指南和进行常规血脂评估是缓解慢性阻塞性肺病风险不可或缺的一部分--大量的教育资源和回忆辅助工具可能有助于缓解 SCI/D 后的慢性阻塞性肺病风险。

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.
脊髓损伤(SCI)会影响运动能力和生活质量。目前正在研究两种脊髓刺激方法,用于恢复脊髓损伤后的站立和行走:硬膜外脊髓刺激(ESCS)和椎管内微刺激(ISMS)。在 ESCS 中,电极被放置在硬脊膜上,而在 ISMS 中,超细线被插入脊髓内。这些方式可能通过不同的途径激活腹侧角的运动区。 本研究的目的是研究ESCS和ISMS激活的神经元分布和神经元类型的差异。 第一步是建立所需的免疫组化(IHC)染色方案。家猪被分为幼稚组(n=2)和阳性对照组(n=1)。天真对照组动物被麻醉 5 小时。阳性对照组动物麻醉 2 小时并在后肢肌肉注射高渗盐水。然后将动物安乐死,取出脊髓进行 IHC 分析。分析中使用了针对神经元活化标志物 cFos 和神经元标记物 NeuN 的抗体。 初步结果表明,ESCS 可激活背角的神经元,并在中间和腹侧区域激活零星的神经元。ISMS 主要激活运动相关网络所在的中间和腹侧区域的神经元。 据我们所知,这是首次研究 ESCS 和 ISMS 的激活类型和部位。这将为我们了解这些刺激模式的作用机制提供基础。

The COVID-19 pandemic has significantly impacted healthcare utilization; however, research has not investigated the impact in the spinal cord injury/dysfunction (SCI/D) population in Canada. To examine healthcare utilization and delivery during the COVID-19 pandemic in individuals with SCI/D. A repeated-cross sectional retrospective longitudinal cohort study design was conducted using health administrative database in Ontario, Canada. In 5,754 individuals with SCI/D, healthcare utilization and delivery (in-person, and virtual) were determined at the 1) pre-pandemic (March 2015 to February 2020), 2) initial pandemic onset (March 2020-May 2020), and 3) pandemic (June 2020 to March 2022) phases. Autoregressive integrated moving average (ARIMA) modelling were conducted to determine pandemic impact on monthly healthcare utilization and delivery. The initial pandemic onset period had a significant reduction of 24% in physician (p=0.0081), 35% in specialist (p<0.0001), and 30% in urologist (p<0.0001) visits, compared to pre-pandemic levels, with a partial recovery as the pandemic progressed. In April 2020, compared to the pre-pandemic period, a significant increase (p<0.0001) for virtual visits for physician, specialist, urologist, and primary care was found. The initial pandemic onset period had a 46% decrease in ED visits (p=0.0764) and 58% decrease in hospital admissions (p=0.0011), compared to the pre-pandemic period. Healthcare utilization dropped in the initial pandemic onset period as physician, specialist, urologist, and ED visits, as well as hospitalization decreased significantly (p<0.05) versus pre-pandemic levels. Virtual visit increases compensated for in-person visit decreases as the pandemic progressed to allow for total visits to partially recover.
COVID-19 大流行对医疗保健的使用产生了重大影响;然而,相关研究尚未调查其对加拿大脊髓损伤/功能障碍(SCI/D)人群的影响。研究 COVID-19 大流行期间 SCI/D 患者的医疗保健使用和提供情况。 我们利用加拿大安大略省的健康管理数据库进行了一项重复性横断面回顾性纵向队列研究。在 5754 名 SCI/D 患者中,确定了在 1) 大流行前(2015 年 3 月至 2020 年 2 月)、2) 大流行初期(2020 年 3 月至 2020 年 5 月)和 3) 大流行(2020 年 6 月至 2022 年 3 月)阶段的医疗保健使用和提供情况(面对面和虚拟)。通过自回归综合移动平均(ARIMA)建模来确定大流行对每月医疗保健使用和提供的影响。 与大流行前的水平相比,大流行开始初期的内科医生就诊率(p=0.0081)、专科医生就诊率(p<0.0001)和泌尿科医生就诊率(p<0.0001)分别大幅下降了 24%、35% 和 30%,随着大流行的发展,部分情况有所恢复。2020 年 4 月,与大流行前相比,内科医生、专科医生、泌尿科医生和初级保健医生的虚拟就诊率显著增加(p<0.0001)。与大流行前相比,大流行初期的急诊室就诊率下降了 46%(p=0.0764),住院率下降了 58%(p=0.0011)。 与大流行前的水平相比,大流行初期的医疗保健利用率有所下降,因为内科医生、专科医生、泌尿科医生和急诊室就诊人数以及住院人数均大幅减少(p<0.05)。随着大流行的发展,虚拟就诊次数的增加弥补了亲自就诊次数的减少,从而使总就诊次数部分恢复。

The Centre for Family Medicine Primary Care Mobility Clinic has been active in developing collaborations at various institutions to further the overall research and clinical objectives of serving individuals with spinal cord injuries (SCI). From these initiatives, The Circulus SCI Primary Care Network (Circulus Network) was established to spark intentional collaborative research, education, training and service in primary care for individuals with SCI. The Circulus Network aims to bridge the gaps in primary care for individuals with SCI through research, education, increasing primary care resources, networking with various stakeholders and general advocacy. The Circulus Network is comprised of a Steering Committee and working groups that are representative of key stakeholders. These groups meet on a rotating monthly basis and are supported by a group process consultant. The Circulus Network informs best practice guidelines and improves knowledge translation by hosting quarterly interactive webinars on topics related to SCI and primary care as well as bi-annual Summits. Since 2021, The Circulus Network has hosted 9 webinars on SCI-related topics with good attendance by network participants.

Rehabilitation after spinal cord injury (SCI) is a life-long process with individuals accessing care in a variety of settings, including centres without SCI-specific services (i.e., non-SCI-specialized centres). Activity-based Therapy (ABT) is a relatively new neurorestorative approach that involves intensive, task-specific movement practice below the level of injury. This study aimed to understand current knowledge, perceptions, and use of ABT by physical and occupational therapists at non-SCI-specialized centres. A qualitative exploratory study using semi-structured interviews was conducted. The Theoretical Domains Framework was used to develop an interview guide that queried therapists’ experiences providing SCI rehabilitation, perceptions of ABT and ABT implementation. Canadian therapists who worked with at least one SCI patient in the last 18 months and practiced at non-SCI-specialized centres participated. Interviews were audio-recorded, transcribed verbatim and analyzed using interpretive description. Four physical and three occupational therapists from acute, inpatient, long-term care and outpatient settings participated. Three themes were determined: 1) Perceived challenges of working with SCI in non-SCI-specialized centres, 2) Current therapy techniques used and 3) Desire for ABT knowledge and implementation strategies specific to non-SCI-specialized centres. It was identified that participants were unknowingly incorporating some components of ABT in their practice. Participants emphasized challenges to ABT implementation, such as knowledge gaps, and expressed a keenness to learn more about ABT. Current implementation of ABT in non-SCI-specialized centres is limited, with a variety of challenges and therapist needs identified. Tailoring ABT education to therapists at non-SCI-specialized centres may increase implementation of ABT at these centres.
脊髓损伤(SCI)后的康复是一个终身过程,患者需要在各种环境下接受治疗,包括没有脊髓损伤专科服务的中心(即非脊髓损伤专科中心)。活动疗法(Activity-based Therapy,ABT)是一种相对较新的神经恢复方法,包括在损伤程度以下进行密集的、针对特定任务的运动练习。本研究旨在了解非 SCI 专科中心的物理和职业治疗师目前对 ABT 的了解、看法和使用情况。 研究采用半结构式访谈进行定性探索研究。理论领域框架用于制定访谈指南,询问治疗师提供 SCI 康复的经验、对 ABT 的看法以及 ABT 的实施情况。参与访谈的加拿大治疗师在过去 18 个月中至少治疗过一名 SCI 患者,并在非 SCI 专科中心执业。对访谈进行了录音、逐字转录并使用解释性描述进行了分析。 来自急诊、住院、长期护理和门诊的四名物理治疗师和三名职业治疗师参与了访谈。确定了三个主题1) 在非 SCI 专科中心从事 SCI 工作所面临的挑战;2) 当前使用的治疗技术;3) 希望获得 ABT 知识和非 SCI 专科中心特有的实施策略。研究发现,参与者在不知情的情况下将 ABT 的某些内容纳入了他们的实践中。参与者强调了实施 ABT 所面临的挑战,如知识差距,并表示渴望了解更多有关 ABT 的知识。 目前在非 SCI 专业中心实施 ABT 的情况有限,存在各种挑战和治疗师的需求。为非 SCI 专科中心的治疗师量身定制 ABT 教育可能会增加 ABT 在这些中心的实施。

Deep vein thrombosis (DVT) is a blood clot that forms in the deep veins and is the third most common cardiovascular disease today. One of the causes of DVT is venous stasis. Current methods of DVT prevention include anticoagulants and mechanical prophylaxis. Anticoagulant use is contraindicated in individuals with bleeding risks and mechanical interventions are often cumbersome and uncomfortable. The overall goal of this project is to investigate a novel method for DVT prevention, termed intermittent electrical stimulation (IES). The current study investigated the effects of IES on healthy typical as well as post-stroke persons. Of the 32 participants, 22 were healthy subjects from Edmonton, and 10 were inpatient post-stroke subjects at the Glenrose Rehabilitation Hospital, Edmonton. A two-channel stimulator was used to administer IES through electrodes placed on the posterior and anterior sides of the leg and was applied in increasing stimulation amplitudes to the gastrocnemius muscle and the resulting plantar flexion force and changes in popliteal and femoral venous velocities were recorded for each stimulation respectively using B-mode ultrasound. IES-induced contractions produced significant increases in venous flow compared to baseline. Small contractions induced by comfortable levels of stimulation in typical and in post-stroke persons were sufficient to increase flow in the popliteal and femoral veins. The results indicate that IES can sufficiently increase venous flow to prevent venous stasis and is comfortable for end users. Incorporation of IES into a clinical device could provide a feasible and effective alternative for DVT prophylaxis.
深静脉血栓(DVT)是一种在深静脉中形成的血栓,是当今第三大最常见的心血管疾病。深静脉血栓形成的原因之一是静脉淤血。目前预防深静脉血栓的方法包括抗凝剂和机械预防。有出血风险的人禁用抗凝剂,而机械性干预措施通常既麻烦又不舒适。 本项目的总体目标是研究一种新型的深静脉血栓预防方法,即间歇性电刺激(IES)。本研究调查了间歇电刺激对健康典型人群和中风后人群的影响。 在 32 名参与者中,22 名是来自埃德蒙顿的健康人,10 名是埃德蒙顿格伦罗斯康复医院的中风后住院病人。使用双通道刺激器通过放置在腿部后侧和前侧的电极对腓肠肌施加IES,刺激幅度不断增大,并使用B型超声波分别记录每次刺激所产生的跖屈力以及腘静脉和股静脉速度的变化。 与基线相比,IES 引起的收缩使静脉流量显著增加。典型患者和中风后患者在舒适的刺激水平下产生的微小收缩足以增加腘静脉和股静脉的流量。 结果表明,IES 能够充分增加静脉流量,防止静脉淤血,而且终端用户感觉舒适。将 IES 纳入临床设备可为预防深静脉血栓提供一种可行而有效的替代方法。

Intraspinal microstimulation (ISMS) is a neuromodulation technique for restoring walking after spinal cord injury. The objective of this study was to fabricate a stretchable ISMS device suitable for pigs, a clinically-relevant animal model. Polyimide-insulated microwires (50µm, Pt-Ir, 80%/20%) were used for fabrication of electrodes. Their tips were de-insulated (∼0.15mm2) and sharpened using nanosecond and femtosecond UV lasers. Microcoils were fabricated from 25μm microwires (Pt-Ir, 80%/20%) to add stretchability to the lead wires. Sixteen microelectrode-leads were connected to a custom, wirelessly controlled stimulator using Medtronic extension cables (Model 37081). The implants were tested in seven domestic pigs and current pulse trains were delivered to various rostro-caudal regions of the lumbar spinal cord (1s, 40Hz, 50µA-300µA) to activate locomotor-related muscle synergies. The kinematics and isometric joint forces of the evoked hindlimb responses were recorded. Graded joint movements were evoked with increasing stimulus amplitude. Changes in the hip, knee, and ankle joints angles evoked by ISMS at 300µA were 17.9±1˚, 28.1±1˚, and 21.6±2˚, respectively. Isometric joint forces evoked by ISMS at 300µA were 12.21±0.91N, 7.4±0.71N, and 1.7±0.15N for knee extension, hip flexion, and ankle flexion, respectively. The movements evoked using the developed ISMS implant could generate full ranges of motion in the joints. The graded responses imply a near-physiological recruitment order of motoneurons, which is necessary for achieving long walking distances without muscle fatigue. The results show the capability of the developed ISMS device in generating movements in pigs, and the implants’ potential for future use in humans.
脊髓内微刺激(ISMS)是一种用于恢复脊髓损伤后行走能力的神经调控技术。本研究的目的是制造一种适用于临床相关动物模型猪的可拉伸椎管内微刺激装置。 制作电极时使用了聚酰亚胺绝缘微线(50 微米,铂-铁,80%/20%)。使用纳秒和飞秒紫外激光对其尖端进行去绝缘处理(∼0.15mm2)和锐化处理。微线圈由 25 微米的微导线(铂-铁,80%/20%)制成,以增加导线的伸展性。使用美敦力公司的延长线(37081 型)将 16 根微电极导线连接到定制的无线控制刺激器上。 在七只家猪身上对植入物进行了测试,并向腰部脊髓的不同喙尾区域(1 秒,40Hz,50µA-300µA)输送电流脉冲序列,以激活与运动相关的肌肉协同作用。记录诱发的后肢反应的运动学和等长关节力。 随着刺激振幅的增大,诱发了分级关节运动。300µA的ISMS诱发的髋关节、膝关节和踝关节角度变化分别为17.9±1˚、28.1±1˚和21.6±2˚。ISMS 在 300µA 下诱发的伸膝、屈髋和屈踝关节等长关节力分别为 12.21±0.91N、7.4±0.71N 和 1.7±0.15N。 使用所开发的 ISMS 植入体诱发的运动可以在关节中产生全范围的运动。分级反应意味着运动神经元的募集顺序接近生理水平,这对于实现无肌肉疲劳的长距离行走是必要的。研究结果表明,所开发的 ISMS 装置具有在猪身上产生运动的能力,而且这种植入物将来有可能用于人类。

Spinal cord injuries (SCI) have a devastating effect on individuals incurring this life-changing event; however, it can also affect those integrally involved in their care. Family caregivers often experience negative outcomes, including high levels of burden, leading to decreased psychological well-being. Cognitive behavioural therapy is the most evidence-based treatment to help people identify and modify thoughts and behaviours contributing to their mental health concerns. However, several resource limitations exist. Guided internet-delivered cognitive behaviour therapy (ICBT) offers an evidence-based and accessible approach to psychosocial service delivery. ICBT improved psychosocial outcomes, including depression among persons with chronic health conditions. However, the efficacy of ICBT has yet to be evaluated among these caregivers. We present the protocol of the Well-being Care Partners Program, a 10-week clinician-guided ICBT program tailored for SCI caregivers to improve their well-being. The program was developed through participatory action research involving seven expert members (i.e., clinicians, people with lived experiences). We aim to recruit 30 participants to pilot this program. Participants will complete measures at baseline, post-intervention, and three months post-intervention. The primary outcome will be feasibility assessed through acceptability and limited efficacy (i.e., depression, anxiety, caregiver burden) as suggested by Bowen’s feasibility framework. This is one of the first pilot trials to test the feasibility, acceptability, and efficacy of a guided ICBT program for SCI caregivers. ICBT is designed to deliver an evidence-based intervention to overcome face-to-face therapy barriers and reach a wider group of patients, including those who might experience difficulties accessing health care.
脊髓损伤(SCI)会对患者造成毁灭性的影响,然而,它也会影响到那些与患者护理息息相关的人。家庭照顾者往往会经历负面的结果,包括高度的负担,导致心理健康水平下降。认知行为疗法是最有实证依据的治疗方法,可帮助人们识别并改变导致其心理健康问题的思想和行为。然而,这种疗法存在一些资源限制。有指导的互联网认知行为疗法(ICBT)为社会心理服务的提供提供了一种以证据为基础的便捷方法。ICBT 改善了社会心理成果,包括改善了慢性病患者的抑郁状况。然而,ICBT 在这些护理人员中的疗效还有待评估。 我们介绍了 "幸福护理伙伴计划 "的方案,这是一项为期 10 周、由临床医生指导的 ICBT 计划,专为 SCI 护理人员量身定制,旨在改善他们的幸福感。该计划是通过参与式行动研究制定的,有七位专家成员(即临床医生、有生活经验的人)参与其中。我们的目标是招募 30 名参与者试行该计划。参与者将完成基线、干预后和干预后三个月的测量。根据鲍恩可行性框架的建议,主要结果将通过可接受性和有限疗效(即抑郁、焦虑、照顾者负担)来评估可行性。 这是首批测试 SCI 护理人员对 ICBT 指导计划的可行性、可接受性和疗效的试点试验之一。ICBT 旨在提供循证干预,以克服面对面治疗的障碍,并惠及更广泛的患者群体,包括那些可能难以获得医疗保健服务的患者。
