Clinical Trial Summary

Spasticity is one of the most common symptoms manifested in humans with spinal cord injury (SCI). However, the neural mechanisms underlying the development of spasticity over time after an acute SCI are not yet understood. Using electrophysiological and imaging techniques along with traditional measurements of neurological recovery in the acute rehabilitation setting including physical exam and functional assessments; the investigators aim to examine the relationship between development of spasticity, residual descending motor pathways and functional and neurological recovery in humans with SCI from acute to subacute phase

Description:

The purpose of this study is to measure changes to motor-evoked potentials (MEPs) and to evaluate if the development of spasticity is related to residual descending motor pathways and to a better neurological recovery and functional improvement in individuals with SCI from the acute to the subacute phase. The investigators will also test for the presence of biological markers in the blood that may correlate with levels of spasticity or neurological recovery and functional improvement, including the presence or absence of neuroplastic genetic polymorphisms (e.g. BDNF Val66Met polymorphism), as well as circulating levels of neuroplastic (e.g. BDNF) or inflammatory factors (e.g. interleukins, TNF) that may affect neuronal growth and functional restoration.

Intervention

Other:
• Measures of spasticity, connectivity and analysis of single nucleotide polymorphisms and biomarkers of inflammation
We will test for presence of biological markers in blood that may correlate with levels of spasticity or neurological recovery and functional improvement, including the presence or absence of neuroplastic genetic polymorphisms (e.g. BDNF Val66Met polymorphism), as well as circulating levels of neuroplastic(e.g. BDNF) or inflammatory factors (e.g. interleukins, TNF) that may affect neuronal growth and functional restoration.
• Analysis of biomarkers
We will test for the presence of biological markers in the blood to compare the distribution of polymorphisms and biomarkers with the spinal cord injury patient population.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Modified Ashworth scale (MAS)	This clinical scale will be used by measuring resistance encountered during manual passive muscle stretching using a six-point ordinal scale (0=no increase in tone, 1/+1=slight increase in tone with a catch and release or minimal resistance at the end or less than half of the range of movement, respectively, 2=more marked increased tone through most of the range of movement but affected parts easily moved, 3=considerable increase in tone and passive movement difficultly, and 4=affected parts rigid)	From the time of admission to the hospital and enrolled in the study till the time of discharge (up to 12 weeks)
Primary	Motor evoked potential (MEP)	Transcranial magnetic stimulation will be delivered and the coil will be positioned over the vertex and moved around this point to determine the optimal position for eliciting a motor evoked potentials (MEPs) in legs muscles.	From the time of admission to the hospital and enrolled in the study till the time of discharge (up to 12 weeks)
Primary	First swing test (FST)	We will use the pendulum test to measure muscle tone at the knee by using gravity to provoke muscle stretch reflexes during passive swinging of the lower limb.	From the time of admission to the hospital and enrolled in the study till the time of the discharge (up to 12 weeks)
Secondary	International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI)	At the time of the admission, after obtaining consent, and at the time of discharge, the chart will be reviewed to obtain the ISNCSCI score	From the time of admission to the hospital and enrolled in the study till the time of discharge (up to 12 weeks)
Secondary	Circulating biomarkers of inflammation and neuroplasticity	In this study, we will focus on tracking expression of key inflammatory cytokines that have been shown to play a pivotal role in activating the major nuclear factor kappa-B (NF-?B) inflammatory pathway. Specifically, we will characterize serum levels of pro-inflammatory cytokines interleukin-1 beta (IL-1ß), interleukin-6 (IL-6), tumor necrosis factor (TNF-a) and anti-inflammatory marker interleukin-10 (IL-10). We will also measure levels of circulating neuroplasticity marker Brain-derived neurotrophic factor (BDNF)	From the time of admission to the hospital and enrolled in the study till the time of discharge (up to 12 weeks)
