Enhancing Recovery in Non-Traumatic Spinal Cord Injury
Enhancing Recovery in Non-Traumatic Spinal Cord Injury: Implementation of an Integrated Program for the Assessment of Rehabilitation Therapies
The investigators have spent the last decade uncovering unique metabolic and functional abnormalities in the brains of patients with spinal cord compression. Degenerative spinal cord compression represents a unique model of reversible spinal cord injury. In the investigator's previous work, they have demonstrated that cortical reorganization and recruitment is associated with metabolic changes in the brains of patients recovering from spinal cord compression and is correlated with recovery and improved neurological scores.
The goal of this study is to combine a rigorous platform of clinical care that includes preoperative evaluation, surgery, and rehabilitation, with state of the art imaging techniques to demonstrate how rehabilitative therapy can increase brain plasticity and recovery of neurological function in patients with spinal cord injury. Neurological function will be carefully evaluated in two groups of patients, those receiving rehabilitation and those not receiving rehabilitation after spine surgery, and will be correlated with the results of advanced imaging.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in levels of N-acetylaspartate (NAA) in the motor cortex
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
It is expected that the group of patients receiving rehabilitation will experience less decline in NAA concentrations as compared to the second group of patients not receiving rehabilitation.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Changes to volume of activation in motor and supplementary motor cortices
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Volume of activation is measured by calculating the voxel number within our selected cortical regions, the motor cortex and supplementary motor cortex, using functional magnetic resonance imaging (fMRI).
Changes in these numbers demonstrate volume of cortical activation changes in these regions.
Following rehabilitation, the investigators expect that the volume of cortical activation of patients, expressed as voxel number, will change between time points compared with changes observed in the control group.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Changes in Graded Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP) scores
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Graded Redefined Assessment of Strength, Sensibility, and Prehension (GRASSP) is an indicator of dorsal and palmar sensation, strength (by myotome) and prehension (grasping).
GRASSP is a standardized measure to assess hand function in ways that are meaningful in the context of a patient's overall ability to complete activities of daily living.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Changes to intensity of cortical activation in motor and supplementary motor cortices
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Intensity of cortical activation is expressed as signal intensity in beta weights.
Following rehabilitation, the investigators expect that the intensity of cortical activation in participants in the intervention group will change between time-points compared with changes observed in the control group.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
RAND Short form (SF)-36 Health Survey Questionnaire
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)]
|
General health status self-administered evaluation tool.
Better scores in the intervention group are expected.
Composite score will be reported.
The range for this score is from 0 to 100, with 100 indicating the best general health status possible.
Subscale scores also range from 0-100 and are simply an average of the scores for each of their relevant questions.
Subscales are combined into a composite score by averaging results of all subscales, which is the methodology specified by the creators of the scale (RAND).
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)]
|
Modified Japanese Orthopaedic Association (mJOA) scale
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
A clinical tool used to evaluate impairment due to cervical spondylotic myelopathy, including loss of sensation, motor abilities in limbs, and bowel and bladder control.
The lowest possible score is a 0 and the highest, 18.
Higher numbers indicate better functioning.
Item scores are simply summed to arrive at the composite score.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Myelopathy Disability Index (MDI)
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
This self-administered questionnaire is used to measure the degree to which myelopathy has affected the participant's ability to perform activities of daily living.
Raw scores will be calculated for each participant and may range from 0 to 30.
To arrive at the participant's raw score, item scores are simply summed.
The final scores used for analysis will be the participant's score expressed as a percentage.
Higher scores indicate greater impairment.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
American Spinal Injury Association (ASIA) Impairment Scale
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
A clinical assessment tool used to classify motor and sensory impairment in persons with myelopathy.
Subscales to be reported include the right and left motor scores (range=0-50 for both) and the right and left sensory scores (range=0-60 for both).
Higher scores indicate less impairment.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
Strength as tested with hand dynamometer
Time Frame: Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
|
A device used to measure grip strength.
|
Measured and reported for all follow-ups throughout study (i.e. pre-operatively, 4 weeks, 6 weeks, 6 months)
