Closed-Loop Deep Brain Stimulation for Refractory Chronic Pain

Chronic pain affects 1 in 4 US adults, and many cases are resistant to almost any treatment. Deep brain stimulation (DBS) holds promise as a new option for patients suffering from treatment-resistant chronic pain, but traditional approaches target only brain regions involved in one aspect of the pain experience and provide continuous 24/7 brain stimulation which may lose effect over time. By developing new technology that targets multiple, complimentary brain regions in an adaptive fashion, the investigators will test a new therapy for chronic pain that has potential for better, more enduring analgesia.

Carry-over Effects of Repetitively Applied Transcutaneous Spinal Cord Stimulation on Spasticity

Spinal cord injury is a devastating condition, causing substantial impairment of vital body functions caudal to the lesion. A major cause of disability stems from spasticity, a common secondary sequelae. Its various clinical manifestations include spasms, clonus, and resistance to passive movements, and often present a major hindrance in rehabilitation, further deteriorate residual motor performance, and negatively impact independence and quality of life. Despite its high prevalence, successful management of spasticity has remained difficult. Standard-of-care treatment modalities are often insufficient or bear the risk of undesirable side effects further accentuating paresis. Epidural stimulation of the lumbar spinal cord via implanted electrodes provides for an alternative approach. It works through modifying the dysregulated neural signal processing of spared spinal circuitry caudal to the injury. Its ameliorative effects on severe lower-limb spasticity have been repetitively reported. Yet, epidural spinal cord stimulation in motor disorders is still off-label, applied in relatively few patients only, also because of its invasive character, the time consuming testing phase for its effective application, and the lack of markers to identify responders in advance. With the development of transcutaneous spinal cord stimulation, a method became available to activate the same input structures to the lumbar spinal cord as with epidural stimulation and hence to induce similar neuromodulatory effects, yet non-invasively, using standard equipment available at rehabilitation centers. A recent proof-of-concept study has shown that a single 30-minute session of transcutaneous spinal cord stimulation controlled various clinical signs of spasticity and augmented residual motor control in spinal cord injured individuals for several hours beyond its application. Further, in one subject, the stimulation was repetitively applied for six weeks, resulting in cumulative therapeutic effects persisting for 10 days after its discontinuation. These observations strongly suggest that the stimulation can induce beneficial neuroplastic adaptations of spared spinal systems and their interaction with residual supraspinal control. The proposed research aims at studying the reproducibility of these findings in a statistically sound cohort of individuals with spinal cord injury and testing the applicability and acceptance of transcutaneous spinal cord stimulation as a home-based therapy.

Effects of In-Wheel Suspension

Manual wheelchairs allow individuals with spinal cord injuries (SCI) to safely and effectively access their environment. However, continual exposure to whole body vibration (WBV) is one of many contributing factors to neck pain, back pain, and fatigue in wheelchair users with SCI. Vibration-reducing in-wheel suspension has the potential to mitigate issues associated with long-term manual wheelchair propulsion. Evidence is lacking on how well these systems work for reducing harmful shock and vibration, pain and fatigue. The purpose of this study is to examine how these wheels change the vibration levels manual wheelchair users are exposed to and how they impact pain and fatigue.

Losing Balance to Prevent Falls After Spinal Cord Injury (RBT+FES)

Falls are a health crisis that cost health care systems billions of dollars/year. This crisis is especially relevant for individuals living with incomplete spinal cord injury (iSCI); 78% fall at least once annually. In able-bodied individuals, falls are prevented by taking reactive steps; however, these reactions are impaired after iSCI. Research in stroke and geriatric rehabilitation showed that reactive balance training (RBT), which targets reactive stepping, prevents falls. We developed a modified version of RBT for the iSCI population. RBT resulted in fewer falls post-training compared to dose-matched, conventional balance training. However, only those who were able to take a step independently and without upper limb support were able to participate in RBT, limiting the applicability of this promising fall prevention method. To address this limitation, we will integrate functional electrical stimulation into RBT (RBT+FES). Our study aims to provide a preliminary evaluation of the efficacy of RBT+FES in participants with chronic, motor iSCI. We will complete a pilot randomized clinical trial (RCT) with 22 participants with iSCI. Participants will be randomly allocated to RBT+FES or to RBT alone (i.e. without FES). They will complete 18 training sessions over 6 weeks (3 sessions/week). Clinical and biomechanical assessments of balance, strength and proprioception will be completed before training, immediately after training, and six months post-training. Falls will be monitored for six months after training through an online survey and regular phone calls. Performance on clinical and biomechanical measures and fall data will be compared between groups. This research will inform the need for, and design of, a larger RCT, and has the potential to transform fall prevention after iSCI.

Locomotor and Bladder Function in Individuals With Acute Spinal Cord Injury

The loss of movement and walking ability significantly affects quality of life after spinal cord injury. In addition, bladder dysfunction consistently ranks as one of the top disorders affecting quality of life after spinal cord injury. The overall objective of this study is to demonstrate that epidural stimulation may be a method for improving stepping, standing and bladder function in individuals with spinal cord injury. With the use of epidural stimulation, the investigators propose to investigate how well the participant can stand and walk and how well the participant's bladder can store or hold urine as well as void or empty urine. The results of this study may aid in the development of treatments to help individuals with spinal cord injuries that are unable to stand or walk and have impaired bladder function.

Effect of Suctioning by Bronchoscope on Postoperative Pulmonary Complications Among Patients With SCI in the PACU

Respiratory failure and dyspnea are common in spinal cord injury (SCI), and in acute situations, any spinal cord lesion above T11 can cause abnormal respiratory function and impair the airway clearance. Although surgical decompression is one of the key early neuroprotective therapies, surgery and general anesthesia disrupt many aspects of respiratory function and may cause a series of postoperative pulmonary complications. Endotracheal suction is important to reduce the risk of lung consolidation and atelectasis. But for patients with respiratory insufficiency such as SCI, ordinary suction is not enough to clear secretions in the deeper airways. And repeated intratracheal suction may even cause some serious complications. Bronchoscopy can generally penetrate into the bronchus of grade 3-4, and fully attract the secretions in it under visual conditions. Its curative effect on pneumonia and atelectasis in the ICU has been affirmed, but no one has yet explored the application in the postoperative care unit .

Treatment of Depression Post-SCI

Depression is more common after a spinal cord injury (SCI) than in the general population. Unfortunately, it is unknown how depression is typically treated in individuals with SCI or if commonly used treatment methods are effective. This study will investigate the safety and impact of a novel method for treating depression called repetitive transcranial magnetic stimulation (rTMS). rTMS is a type of non-invasive brain stimulation. Fourteen individuals with a cervical or thoracic level SCI and depression will complete an approved treatment plan using rTMS. Participants will be treated using rTMS five days a week for four weeks. After four weeks of treatment, the study team will review the safety of rTMS and assess changes in depressive symptoms. If the results are positive, larger studies can be designed to develop better treatment options for individuals with SCI and depression.

In-Home Adjustment of New Spinal Cord Injury Caregivers

To improve spinal cord injury (SCI) rehabilitation through stronger informal caregiving, the proposed study will modify and evaluate a telehealth Transition Assistance Program (TAP) for informal caregivers of individuals with SCI during the transition from hospital to home. The TAP was previously developed for stroke caregivers and has been found to decrease caregiver strain and depression. In the proposed study, the TAP will be modified for SCI and implemented at a state-of-the-art SCI rehabilitation facility with a very high volume of SCI treatment and with telehealth technology already in place through which to test the intervention.

Internet-delivered Cognitive Behavioural Therapy for Persons With Spinal Cord Injury

In Canada the prevalence of spinal cord injury (SCI) is approximately 85,556, with incidence rates of traumatic and non-traumatic SCI at 1,785 and 2,286 cases per year, respectively. Common secondary health conditions experienced by individuals with SCI include psychological distress and pain. Appropriate management of these secondary conditions, through a multidisciplinary approach, is imperative as they have been shown to contribute to slower recovery, increased negative outcomes, and greater rates of rehospitalizations and health care utilization. However, resource limitations can restrict the ability of service providers to deliver these integrative biopsychosocial approaches in the community. Guided internet delivered cognitive behavioural therapy (ICBT) program offers an alternative approach for psychosocial service delivery in the community. The program provides online structured self-help modules based on the principles of cognitive behavioural therapy (CBT) in combination with guidance from a coach through weekly emails and telephone calls. ICBT was shown to have similar effects to face-to-face CBT. Results from the investigator's pilot pre-post study (ClinicalTrials.gov: NCT03457714), found significant effects of guided ICBT on primary outcome of depression (d=1.20, p=.02) post-intervention and gains were maintained at 3-month follow-up among persons with SCI. Significant improvements in secondary outcomes including pain interference, resilience, positive affect, self-efficacy, ability to participate, and grief were also found.These studies demonstrate that guided ICBT is a safe and effective alternative to face-to-face interventions and it may be beneficial for underserviced populations. In the proposed trial, the investigators will examine the efficacy of the Guided ICBT Chronic Conditions Course for persons with SCI versus an online SCI Rehabilitation Education program. All participants will complete questionnaires prior to the start of the program, before each lesson of the program, once they have completed the program, and 3 months after completing the program. The primary outcome measures include anxiety and depression. As part of the battery of questionnaires administered after the completion of the program, clients will be asked to rate the program content, the overall service, and their satisfaction with the program.

Effect of a Novel Intervention Using Daily Intermittent Hypoxia and High Intensity Training on Upper Limb Function in Individuals With Spinal Cord Injury

Currently, there are a variety of approaches utilized in attempts to improve upper extremity function, including: traditional therapy, neuroprostheses, botulinum toxin injections, or surgical interventions. In addition, regenerative and restorative therapies, such as: epidural stimulation, functional electrical stimulation, and stem cell therapies, show promise in animal models, but are not ready for clinical translation. Subsequently, there is a clear need to develop new strategies that can stimulate spinal plasticity and strengthen existing synaptic connections in order to maximize the benefits of training paradigms. This study proposes the examine the effects of Acute Intermittent Hypoxia (AIH) in combination with upper extremity training, over the course of a month, to evaluate changes in upper extremity function, dexterity, and ability to complete activities of daily living. The use of acute intermittent hypoxia (AIH) has been demonstrated, through human and animal studies, to be an effective way of increasing spinal motor excitability and strengthening residual synaptic connectivity. AIH utilizes short duration (<2 min) exposures to reduced oxygen levels (~10% inspired oxygen), with alternating exposures to air with normal oxygen levels (~21% inspired oxygen). Previous publications demonstrate that AIH is a safe and effective intervention to modify motor function in individual with chronic incomplete spinal cord injuries. The use of AIH has been shown to influence the activation in musculature, within 60-120 minutes of administration. In addition, when coupling AIH with overground gait training, an increase in functional endurance, as evaluated through the 6 minute walk test, and gait speed, as evaluated through the 10 meter walk test, were demonstrated. In addition, the use of hypoxic training has been studied in healthy individuals and athletes; however, literature examining the effect of a single bout of AIH on performance is limited.

Neuromodulation of Spinal Locomotor Circuitry to Elicit Stepping After Pediatric Spinal Cord Injury

Spinal cord injury (SCI) results in damage to the descending neural pathways and leads to the immediate dysfunction of multiple physiological systems below the level of injury. Like adults, children with SCI suffer from neuromuscular paralysis which results in the inability to sit, stand, and walk. Current therapeutic interventions largely aim to compensate for paralysis to achieve mobility based on the assumption that damage to the central nervous system is permanent and irreversible, e.g. use of braces, standers, and wheelchairs. The objective of this proposal is to investigate the use of transcutaneous spinal stimulation (TcStim) to enable stepping in children with chronic SCI. The investigators will recruit 8 participants, ages 4-12 years with chronic, acquired SCI, T10 and above and non-ambulatory. The aims of this proposal are to 1) investigate the mechanisms of locomotor-specific regulation in the spinal neural circuitry of children with acquired SCI using single vs. multi-site TcStim, 2) investigate the capacity of the lumbosacral spinal cord for integration of task-specific input (e.g. load, speed) during facilitated stepping with and without TcStim, and 3) investigate the training effects of TcStim on the ability to step. Outcomes will provide a necessary initial step in the translation of scientific findings for neuromodulation from adults with SCI to children.

Photovoice for Spinal Cord Injury to Prevent Falls

Falls is a health crisis that costs health care systems billions of dollars each year. This crisis is especially relevant for people living with spinal cord injury (SCI) as most of these people will fall at least once per year. Falls can cause injury and a fear of falling, which often causes people to restrict their mobility and daily activities. Despite its importance, fall prevention for people with SCI is understudied, and as a result, there is a lack of treatments to address their high fall risk. We will evaluate a new treatment for fall prevention. Photovoice is a method that uses photographs and dialogue to share experiences, understand an issue and promote positive change. Specifically, we aim to evaluate the effects of photovoice on confidence related to balance and falls, occurrence of falls, participation in daily activities and quality of life among people living with SCI. We also aim to understand participants' experiences with photovoice as a fall prevention program. To achieve these aims, 40 individuals living with SCI will participate in this study. Participants will complete a six-week photovoice program that involves photo assignments, individual interviews and group meetings. The program will be led by a person with SCI and a member of the research team with a background in physical or occupational therapy or kinesiology. Questionnaires will be used throughout the study to measure confidence, participation and quality of life. The occurrence of falls will be tracked for 12 weeks before and after the photovoice program. At the end of the study, each participant's experiences with photovoice will be collected through interviews. The proposed research will address a critical gap in SCI rehabilitation, namely effective fall prevention, to improve well-being after SCI. The research findings will inform the need for, and design of, a larger clinical trial, and has the potential to transform fall prevention after SCI.
