Effect of Suctioning by Bronchoscope on Postoperative Pulmonary Complications Among Patients With...
Spinal Cord InjuriesRespiratory 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 .
Closed-loop Functional Spinal Cord Stimulation in Patients With Spinal Cord Injury
Spinal Cord InjuriesThe purpose of this experiment is to evaluate the efficacy of Closed-loop Functional Spinal Cord Stimulation on Walking Rehabilitation in Patients after Spinal Cord Injury
Functional Electrical Stimulation (FES) and Reconstructive Tetraplegia Hand and Arm Surgery
Spinal Cord Injury CervicalFES is a common and established method in the rehabilitation of persons with spinal cord injury (SCI). Some known effects of FES were investigated in several studies e.g. avoiding disuse and denervation atrophy, improving muscle force, power output and endurance changing muscle fibre type, increasing cross sectional area of muscle, increasing muscle mass, activation of nerve sprouting, reducing spasticity and motor learning. Most of the studies investigated the impact of FES in the lower limbs. For the upper extremities fewer studies exist. However, it is supposed that the effects of FES are similar. In the rehabilitation of persons with tetraplegia, FES, especially the stimulation of the upper extremities triggered by electromyography (EMG) is an established method to generally improve hand and arm function. However, none of those studies has investigated the effect of FES in combination with reconstructive tetraplegia hand surgery. Improved muscle strength is supposed to improve the functional outcome in participation. Additionally, FES could increase the motor learning process. Supported by the clinical observation we hypothesize that FES has a positive influence on the outcome of surgical reconstruction of tendon and/or nerve transfers.
Mild Intermittent Hypoxia and Its Multipronged Effect on Sleep Apnea
Obstructive Sleep ApneaSpinal Cord InjuriesMild intermittent hypoxia (IH) initiates sustained increases in chest wall and upper airway muscle activity in humans. This sustained increase is a form of respiratory plasticity known as long-term facilitation (LTF). Repeated daily exposure to mild IH that leads to the initiation of LTF of upper airway muscle activity could lead to increased stability of the upper airway. In line with PI's laboratory's mandate to develop innovative therapies to treat sleep apnea, this increased stability could ultimately reduce the continuous positive airway pressure (CPAP) required to treat obstructive sleep apnea (OSA) and improve compliance with this gold standard treatment. Improved compliance could ultimately serve to mitigate those comorbidities linked to sleep apnea. Moreover, in addition to improving CPAP compliance numerous studies indicate that mild IH has many direct beneficial effects on cardiovascular, neurocognitive and metabolic function. Thus, mild IH could serve as a multipronged therapeutic approach to treat sleep apnea. In accordance with this postulation, our proposal will determine if repeated daily exposure to mild IH serves as an adjunct therapy coupled with CPAP to mitigate associated co-morbidities via its direct effects on a variety of cardiovascular, metabolic and neurocognitive measures and indirectly by improving CPAP compliance. Modifications in autonomic (i.e. sympathetic nervous system activity) and cardiovascular (i.e. blood pressure) function will be the primary outcome measures coupled to secondary measures of metabolic and neurocognitive outcomes.
Intervention on Bone Health in Wheelchair Users
Bone LossSpinal Cord Injuries4 moreThe low mechanical loading of bones among wheelchair users leads to an increased risk of bone fractures and associated complications due to low bone mineral density (BMD). Adding mechanical loading through physical activity in combination with optimizing nutrition may counteract these negative consequences in wheelchair users and thereby provide positive impact for bone health, as well as for physical and mental health. In this project, a multidisciplinary team will tailor a bone-specific exercise and nutrition program to increase BMD in sport active and non-active wheelchair users with initial low BMD.
Improving Adherence to Spinal Cord Injury Exercise Guidelines Using Smartphone Technology and E-coaching...
Spinal Cord InjuriesThe goal of this research is to increase physical activity among individuals with a spinal cord injury (SCI) through a customized, interactive smartphone-based health app and e-coaching using three phases: (1) leading focus groups of potential app users and clinicians to gain information regarding health apps preferences for optimal consumer use, (2) conducting a usability study of the customized app to determine the quality and implement further changes for optimization, and (3) conducting a sequential multiple assignment randomized trial (SMART) to determine the most effective adaptive intervention to improve exercise adherence. A SMART trial will be used to determine when and how to adapt dosage, timing, and delivery to increase adherence and address low-response behaviors. In Stage-I, the investigators will compare outcomes among participants using a generic, non-interactive exercise app (Group 1) to a customized, interactive app that can gain information through frequent Ecological Momentary Assessments (EMA) that will be used to modify each participant's exercise programs (Group 2). After 12 weeks, participants who are not meeting the exercise guidelines at least 50% of the time will also be asked to participate in motivational interviewing-based e-coaching either two or four times per month in addition to their originally assigned intervention (Stage-II). By completing these three phases, this project addresses deficiencies in exercise levels and compliance by implementing an individualized exercise prescription, an adaptive intervention for low responders, a way to address barriers to exercise, and a free smartphone app for broad implementation.
Activating Spinal Circuits to Improve Walking, Balance, Strength, and Reduce Spasticity
Incomplete Spinal Cord InjurySpasticity1 moreFor many people with spinal cord injury (SCI), the goal of walking is a high priority. There are many approaches available to restore walking function after SCI; however, these approaches often involve extensive rehabilitation training and access to facilities, qualified staff, and advanced technology that make practicing walking at home difficult. For this reason, developing training approaches that could be easily performed in the home would be of great value. In addition, non-invasive spinal stimulation has the potential to increase the effectiveness of communication between the brain and spinal cord. Combining motor skill training (MST) with transcutaneous spinal stimulation (TSS) may further enhance the restoration of function in persons with SCI. Therefore, the purpose of this study is to determine if moderate-intensity, MST can improve walking-related outcomes among persons with SCI and to determine if the addition of non-invasive TSS will result in greater improvements in function compared to training alone.
Extracorporeal Shockwave Therapy for Spasticity in People With Spinal Cord Injury
Spinal Cord InjuriesSpasticity6 morePeople with spinal cord injury (SCI) experience a host of secondary complications that can impact their quality of life and functional independence. One of the more prevalent complications is spasticity, which occurs in response to spinal cord damage and the resulting disruption of motor pathways. Common symptoms include spasms and stiffness, and can occur more than once per hour in many people with SCI. Spasticity can have a negative impact over many quality of life domains, including loss of functional independence, activity limitations, and even employment. Its impact on health domains is also pronounced, with many people who have spasticity reporting mood disorders, depression, pain, sleep disturbances, and contractures. Spasticity can interfere with post-injury rehabilitation and lead to hospitalization. There are many treatments for spasticity in this population. However, many do not have long-term efficacy, and, if they do, they are often pharmacological in nature and carry side effects that could limit function or affect health. The goal of this pilot, randomized-controlled study is to investigate the potential efficacy and safety of a non-invasive treatment with a low side effect profile, extracorporeal shockwave therapy (ESWT). ESWT has shown some benefits in people with post-stroke spasticity with no long term side effects. Thirty individuals with chronic, traumatic SCI will be recruited. Fifteen will be provided with ESWT while the other fifteen will be given a sham treatment. Clinical and self-report measures of spasticity and its impact on quality of life will be collected, as well as quantitative ultrasound measures of muscle architecture and stiffness. The ultimate goal of this pilot project is to collect the data necessary to apply for a larger randomized-controlled trial. Conducting a larger trial will allow for a more powerful estimation of safety and efficacy of ESWT as a treatment for spasticity in people with SCI.
Targeted HD-tDCS to Improve Upper Limb Rehabilitation in SCI
Spinal Cord InjuriesSpinal Cord DiseasesThe proposed project seeks to maximize the functional recovery achieved during the rehabilitation of the paretic upper limbs in individuals with SCI. The investigation will work towards optimizing the use of transcranial direct current stimulation (tDCS), an adjunct known to improve the effectiveness of rehabilitation. In particular, the relationship between the specificity of current delivery and functional benefit will be explored, and findings may lead to a framework that can be translated to the clinic setting.
