Study summary

A multicenter, international, prospective, observational case series patient cohort with incomplete cervical SCI without instability will be enrolled to obtain information and data that could inform the feasibility of administering a set of additional core and optional outcome assessments in cervical SCI patients to capture the aspects of neurologic impairment. Baseline, intraoperative, and postoperative characteristics, including demographics, injury details, treatment details, neurological assessments, gait and balance assessments and upper extremity assessments, will be recorded for adult patients.

Read the detailed description

This prospective multicenter study will enroll 50 adult patients with acute traumatic cervical SCI with ISNCSCI AIS Grade D or sensory deficits only without biomechanical instability.

Patients will be assessed at the baseline visit and subsequently be followed up at 3 and 6 months. All decisions regarding the treatment and clinical management will be left to the attending spinal surgeon and will follow the local standard of care.

The core outcome assessments include:

  • Neurological status by the ISNCSCI
  • Patient-reported outcome measures (PROMs) of Short Form-36 (SF-36) v2 and Neuropathic Pain Scale (NPS)
  • The Spinal Cord Independence Measure (SCIM) v3
  • Gait and balance evaluated using the ten-meter walk test (10mWT) and Walking Index for Spinal Cord Injury (WISCI) v2
  • Upper extremity impairment evaluated using the grip strength with digital dynamometry, pinch strength (key pinch and tip-to-tip pinch), and the Partial Graded Redefined Assessment of Strength Sensibility and Prehension (GRASSP) v2.

All core outcome assessments will be performed at the baseline, 3-, and 6-month visits except for the PROMs, SCIM v3, key pinch and tip-to-tip pinch, which will be assessed only at the 3- and 6-month visits.

The optional outcome assessment is the multiparametric quantitative spinal cord magnetic resonance imaging (MRI)/diffusion tensor imaging (DTI) which will be performed at baseline, 3-, and 6-month visits if it is done at the surgeon's discretion.

The goal of this study is to obtain information and data that could inform the feasibility of administering a set of additional core and optional outcome assessments in cervical SCI patients with incomplete tetraplegia without spinal instability to capture the aspects of neurologic impairment that may not be well represented in the ISNCSCI examination.

Study population

Patients with traumatic incomplete cervical SCI without instability

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 18-80 years, inclusive
  • Diagnosis of acute traumatic cervical SCI with ISNCSCI AIS Grade D or sensory deficits only within 92 hours post injury
  • Cervical neurological level of injury (C2-C8)
  • MRI, using any imaging protocols (conventional, multiparametric, or quantitative), taken according to standard of care
  • Presence of spinal cord compression on the MRI
  • Absence of biomechanical instability to the extent that would mandate stabilization surgery by the treating surgeon
  • Ability to provide according to the IRB/EC defined and approved procedures

Exclusion criteria

Exclusion Criteria:

  • Nontraumatic SCI
  • Concomitant traumatic brain injury or polytrauma that could preclude accurate or reliable assessments of the outcome assessments
  • Uncontrolled severe systemic diseases, preexisting neurological, musculoskeletal, or general medical conditions which could preclude accurate assessments or FUs
  • Individuals unable to undergo MRI
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. The proportion of the core outcome assessments successfully completed at each visit

    For baseline and each FU visit, the completion status of each core outcome assessment

    Time frame: up to 6 months

  2. Time required to complete the individual core outcome assessments

    For baseline and each FU visit, the time required for completion for each core outcome assessment will be recorded (start time, end time, and duration in mins)

    Time frame: up to 6 months

  3. Total time required to complete all core outcome assessments at each visit

    The time required for completion will be measured to the nearest 0.1 second by using a digital timer, and the timing should start at the start of giving instructions to the patients or explaining the tests to the patients (start time) and end when the final score of the test is obtained (end time).

    Time frame: up to 6 months

  4. Completion rate of individual core outcome assessments (and their scorings if applicable)

    Completion rate of individual core outcome assessments at each visit.

    Time frame: up to 6 months

  5. Completion rate of the multiparametric quantitative spinal cord MRI/DTI

    Completion rate of the multiparametric quantitative spinal cord MRI/DTI

    Time frame: up to 6 months

  6. FU visit compliance rate and reasons for non-compliance

    Completion status of FU visits, recorded at 3- and 6-month visits

    Time frame: up to 6 months

  7. Patient accrual rate

    Whether the patient drops out from the study, recorded at the time of dropout

    Time frame: up to 6 months

Secondary outcomes

  1. Results from the core outcome assessment ISNCSCI

    Motor and sensory scores (motor score 0-100, pin prick score 0-112), AIS Grades, Clinical syndrome (Central Cord/Brown-Sequard/Anterior Cord/Conus Medullaris/Cauda Equina/No clinical syndrome/Not assessed)

    Time frame: up to 6 months

  2. Results from the core outcome assessment SF-36 v2

    Eight scale scores (0-100): physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, general mental health, social functioning, energy/fatigue or vitality, and general health perceptions

    Time frame: up to 6 months

  3. Results from the core outcome assessment Neuropathic pain score

    Score 0-100

    Time frame: up to 6 months

  4. Results from the core outcome assessment SCIMv3

    Three subscales: Self-care (0-20), Respiration and Sphincter Management (0-40), Mobility (room and toilet, 0-40)

    Time frame: up to 6 months
