Human spinal cord injuries (SCI) disrupt the pathways between brain and spinal cord, resulting in substantial impairment and loss of function. Currently, we do not have the ability to precisely quantify the "functional" level of motor injury. The aim of this study is to determine if high-density surface electromyography imaging (SEI) can be used to characterize the location and extent of the spinal lesion. SEI is a safe and non-invasive technique, which uses several electrodes to provide a map of muscle activity...

Afferent electrical stimulation is known to augment the effect of rehabilitative therapy through use-dependent cortical plasticity. Experiments pairing transcranial magnetic stimulation (TMS) with peripheral nerve stimulation (PNS) have shown a timing-dependent effect on motor evoked potential (MEP) amplitude suggesting that PNS applied in closed-loop (CL) mode could augment this effect through positive reinforcement. We present early results from a clinical trial in which an EEG brain-machine interface (BMI) was used to apply PNS to two subjects in response to motor intent detected from sensorimotor cortex in a cue-driven hand grip task...

Interventions that can produce targeted brain plasticity after human spinal cord injury (SCI) are needed for restoration of impaired movement in these patients. In this study, we tested the effects of repetitive cervicothoracic transspinal stimulation in one person with cervical motor incomplete SCI on cortical and corticospinal excitability, which were assessed via transcranial magnetic stimulation with paired and single pulses, respectively. We found that repetitive cervicothoracic transspinal stimulation potentiated intracortical facilitation in flexor and extensor wrist muscles, recovered intracortical inhibition in the more impaired wrist flexor muscle, increased corticospinal excitability bilaterally, and improved voluntary muscle strength...

BACKGROUND: Controversy exists regarding the management of unstable Jefferson fractures, with some surgeons performing reduction and immobilization of the patient in a halo vest and others performing open reduction and internal fixation. This study compares the clinical and radiological outcome parameters between posterior atlantoaxial fusion (AAF) and occipitocervical fusion (OCF) constructs in the treatment of the unstable atlas fracture. MATERIALS AND METHODS: 68 consecutive patients with unstable Jefferson fractures treated by AAF or OCF between October 2004 and March 2011 were included in this retrospective evaluation from institutional databases...

BACKGROUND: and Purpose: Several studies have looked for an association between radiological findings and neurological outcome after cervical trauma. In the current literature, there is a paucity of evidence proving the prognostic role of soft tissue damage or bony integrity. Our objective is to determine radiological findings related to neurological prognosis in patients after incomplete acute traumatic cervical spinal cord injury, regardless of initial neurological exam. MATERIAL AND METHODS: We retrospectively reviewed patients with acute traumatic cervical Spinal Cord Injury who had an MRI performed within the first 96 hours...

INTRODUCTION: Cruciate Paralysis is a rare incomplete spinal cord syndrome presenting as brachial diplegia with minimal or no involvement of the lower extremities. It occurs as a result of trauma to the cervical spine and is associated with fractures of the axis and/or atlas. Diagnosis is confirmed on MRI and is managed by treatment of the underlying pathology. Prognosis depends on the extent of spinal cord injury and the exact cause. CASE PRESENTATION: A 20-year-old male presented to the casualty with a history of an injury to the back of the head as a result of a fall...

To investigate the prognostic values of clinical factors 72 h within traumatic cervical spinal cord injury (TCSCI). Data were extracted from the medical materials of 57 TCSCI cases. AIS was used as the outcome measure and divided into dichotomous variables by two methods, i.e. "complete(AIS = A)/incomplete(AIS ≠ A) SCI" and "motor complete(AIS = A or B)/incomplete(AIS ≠ A and B) SCI". Relationships between evaluated factors and outcomes were investigated by univariate and multivariate methods...

Cervical spinal cord injury (cSCI) occurs in over half of all cases of traumatic spinal cord injury (SCI), yet we lack therapies that can generate significant functional recovery in these patients. The development of animal models of cSCI will aid in the pre-clinical assessment of therapies and in understanding basic pathophysiological mechanisms. Here, we describe a clinically relevant model of cervical contusion-compression injury in the mouse. Using a modified aneurysm clip, we generated a bilateral, incomplete injury that mimics contusion-compression injuries most commonly observed in humans...

BACKGROUND: Preclinical investigations in animal models demonstrate that enhanced upper limb (UL) activity during rehabilitation promotes motor recovery following spinal cord injury (SCI). Despite this, following SCI in humans, no commonly applied training protocols exist, and therefore, activity-based rehabilitative therapies (ABRT) vary in frequency, duration, and intensity. Quantification of UL recovery is limited to subjective questionnaires or scattered measures of muscle function and movement tasks...

Traumatic neurologic injury in contact sports is a rare but serious consequence for its players. These injuries are most commonly associated with high-impact collisions, for example in football, but are found in a wide variety of sports. In an attempt to minimize these injuries, sports are trying to increase safety by adding protection for participants. Most recently is the seemingly 'safe' sport of Bubble Soccer, which attempts to protect its players with inflatable plastic bubbles. We report a case of a 16-year-old male sustaining a cervical spine burst fracture with incomplete spinal cord injury while playing Bubble Soccer...

BACKGROUND: After cervical spinal cord injury, current options for treatment of upper extremity motor functions have been limited to traditional approaches. However, there is a substantial need to explore more rigorous alternative treatments to facilitate motor recovery. OBJECTIVE: To demonstrate whether anodal-primary motor cortex (M1) excitability enhancement (with cathodal-supra orbital area) (atDCS) combined with robot-assisted arm training (R-AAT) will provide greater improvement in contralateral arm and hand motor functions compared to sham stimulation (stDCS) and R-AAT in patients with chronic, incomplete cervical spinal cord injury (iCSCI)...
