Acute Effects of Pharmacological Neuromodulation on Leg Motor Activity in Patients With SCI Treated...
Spinal Cord InjuriesDrug EffectIn a current first-in-man study, called Stimulation Movement Overground (STIMO) (NCT02936453; CER-VD: 04-2014; Swissmedic: 2016-MD-0002), epidural electrical stimulation (EES) of the spinal cord is applied to enable individuals with severe spinal cord injury (SCI) to complete intensive locomotor neurorehabilitation training. In this clinical feasibility study, it was demonstrated that EES results in an immediate enhancement of locomotor functions and that when applied repeatedly as part of a neurorehabilitation program, EES can progressively improve leg motor control in individuals with severe SCI. Mechanistically, EES acts trans-synaptically upon spinal circuitries through the electrical stimulation of proprioceptive fibers. It is assumed that this stimulation does not increase the level of availability of monoamine neurotransmitters below the SCI level, which are essential for lower extremity movement generation. Specifically, in a non-injured individual, dopamine and serotonin synthesized in the brain and brainstem are released by fibers diffusely innervating the spinal cord, serving to critically mediate excitability of motor neurons and interneurons in lumbar and sacral spinal level. Spinal cord injury would partially or entirely disrupt these modulation pathways, resulting in a detrimental lack of crucial neurotransmitters below the injury level. This lack of endogenous neurotransmitters could potentially be compensated for by pharmacological agents promoting the neurochemical environment necessary for locomotion.
Restorative Neuromodulation for Lower Extremity Functions
Spinal Cord InjuriesStroke1 moreThe overall objective of the proposed study is to restore lower-extremity functions of paraplegic individuals. Paralysis following Stroke or spinal cord injury (SCI) result harsh sufferings including lifelong dependence on wheelchairs and thus often life threatening conditions such as pressure sore resulted from the immobility. Recently, electrical stimulation targeting the lumbosacral spinal cord has shown activation of spinal circuits that control standing and walking functions; while body-weight supported locomotor training has shown overall health improvement of the paraplegic patients through activity dependent rehabilitation. In the current project we aim to combine the trans-spinal electrical stimulation and locomotor training in an efficient, cost-effective and simplified manner for functional rehabilitation. In this proposed study, Stroke and SCI paraplegics will be regularly trained to stand and walk on a body-weight support system with the aid of lower-limb orthoses and trans-spinal electrical stimulation. In progressive weeks the orthotic support of the lower-limb would be slowly lifted off and only the stimulation therapy will be delivered during the locomotor training. Repetitive training with this combination therapy, the spinal pathways would likely reorganize and would promote long-term rehabilitation of the lower-extremity. After successful demonstration of this in our laboratory settings, we aim to transform this technology for community use.
Motor Learning Approach for Manual Wheelchair Users
Spinal Cord InjuriesThe overall purpose of this project is to pilot test a manual wheelchair (MWC) training program based on motor learning theory to improve wheelchair propulsion for manual wheelchair users (MWUs) with spinal cord injury (SCI).
Immediate Effects of Stepping Training Using External Feedback in Spinal Cord Injury Patients
Spinal Cord InjuriesDoes stepping training with or without external feedback change functional ability of ambulatory patients with iSCI immediately after training? Are there significant differences between the immediate effects of stepping training with or without external feedback in ambulatory patients with iSCI?

Exoskeletal-Assisted Walking in SCI Acute Inpatient Rehabilitation
Spinal Cord InjuriesInpatientThe purpose of this research study is to test the effect of early exoskeletal-assisted walking (EAW) training (combined into regular acute inpatient rehabilitation (AIR)) on improving functional recovery and reducing pain and inflammation. Powered exoskeletons are a technology that offer standing and walking for certain persons with spinal cord injury (SCI) who meet the using indication of the device and have been used in the chronic SCI population with positive benefits in ability to move, daily function (such as bathing and dressing), body composition (such as lean and fat tissue mass), and quality of life (QOL). Despite the potential for EAW to promote functional recovery and reduce secondary medical complications (such as urinary tract infections and pain), no reports exist on the use of exoskeletons in AIR.
Random Noise Stimulation to Enhance Cortical Drive & Improve Hand Function
Spinal Cord InjuriesTetraplegia1 moreCervical spinal cord injury (SCI) results in hand and arm function impairments and decreased independence in performance of daily activities such as bathing, eating, dressing, writing, or typing. Recent approaches that involve the application of non-invasive brain stimulation have the potential to strengthen the remaining connections between the brain and the spinal cord for improved hand function. Combining brain stimulation with performing upper limb functional tasks may further increase the ability of individuals with tetraplegia to use their hands. The purpose of this study is to investigate if "random noise", a special type of brain stimulation that most people cannot feel, can be used to enhance upper limb function in individuals with spinal cord injury. Specifically, the investigators will examine if a combined treatment protocol of random noise and fine motor training results in greater improvements in motor and sensory hand function compared to fine motor training alone.
Manually Assisted Cough Technique and Incomplete Cervical Spine Injury
Spinal Cord InjuriesTo determine the effectiveness of manually assisted cough technique on peak cough flow and pulmonary functions in patients with incomplete cervical spine injury. Previous studies were designed to target only a small sample. Level and American Spinal Cord Injury Association (ASIA) scale were not specified so this study covers this aspect.

Spinal Cord InjuriesPsychological DistressThe purpose of this preliminary study is to examine the effects of a guided online acceptance and commitment therapy (ACT) intervention combined with psychoeducation on people with spinal cord injury (SCI) who experience psychological distress.
Effect of Adaptive Sports After Acquired Physical Disability
Spinal Cord InjuriesSports Physical TherapyThis study is a cross-sectional trial which aims to evaluate the effect of practicing a physical activity on different domains of the ICF among individuals with an acquired physical disability. Two different groups of individuals with a spinal cord injury will be enrolled: one composed of subjects who manage to reach the WHO's recommendations regarding physical activity, and the other of subjects who do not.
