Source of uncertainty
Current evidence and reason for uncertainties

No formal diagnostic criteria published for DCM.

No systematic reviews, scoping reviews or guidelines identified.

  • Original suggestions*

    * This list shows the original survey submission(s) that informed the indicative uncertainties and the resulting priority question.

    Not sure if the 'degenerative,' aspect has been made clear to me thus far.

    Better MRI and CT grading of DCM

    A qualitative study (potentially focus group design) on patient experiences on the journey to diagnosis (with a view to streamlining services and access to timely assessment and imaging)

    What MRI changes signify symptomatic DCM rather than asymptomatic degenerative change?

    Soft signs of degenerative myelopathy?

    Does the presence of hyperintensity signal in the spinal cord mean DCM? Is there a minimum pattern of clinical signs that define DCM?

    How to diagnose the cause? History taking alone?

    Could any microstructural, functional or biochemical abnormalities detected with MRI (such as diffusion MRI, fMRI, MR spectroscopy) or electrophysiological tests (evoked potentials) be used as markers of DCM in addition to MR signs of cervical cord compression an clinical symptoms and/or signs?

    Are there reliable surrogate markers in order to diagnose DCM?  

    If there is no canal stenosis is there a diagnostic tool that can diagnose DCM with certainty as change in spinal cord signal (called myelomalacia) is too late?

    What are the evidence-informed clinical tests for the diagnosis of DCM?

    Is there a standard protocol for radiologists to read and report on DCM?  

    What are the typical presentations?

    Does the presence of high signal on MRI mean that we are too late in treating effectively?  2. Can we diagnose clinically before high signal on MRI?

    Can an objective method be developed to diagnose DCM, such as electrophysiology, blood biomarker or MRI diagnostic test?

    What other criteria one should look at ? Are there any other clinical signs other than described in the clinical evaluation ?

    Why is it that it takes a MRI to diagnose cervical myelopathy?   I had symptoms way before the doctors figured out what I have.

    How important is spinal cord signal change in defining DCM?  Which are the most important neurological findings in defining DCM?  How important are spinal canal measurements? 

    What type of patient should we consider taking MRI?

    MRI criteria of DCM. MR changes of the spine and/or spinal cord which is predictable for DCM?

    I had to see many doctors and each had different thoughts.    finally saw a neurologist who told me it was DCM but even then there was uncertainty about how to proceed.  so I guess I would like more clear guidelines about how to diagnose

    What should be the main diagnostic tool for DCM detection - clinical findings, evoked potentials, MRI?

    In the need of a good diagnosis-treatment algorythm in DCM we do need a prognostic classification system. Can we classify DCM like we do in Lumbar Spinal Stenosis by the Schizas system ?

    What are the common presenting symptoms for DCM? What role do upper / lower limb changes (sensory, motor, DTR/ UMN findings play in this diagnosis? When is cross sectional imaging relevant?

    Are there any gold-standard manual tests (non-neurological assessment) for effective diagnosis of DCM?
