Inclusive Trial Designs in Acute Spinal Cord Injuries: Prediction-Based Stratification of Clinical Walking Outcome and Projected Enrolment Frequencies

Effects of early mobilization within 48 hours of injury in patients with incomplete cervical spinal cord injury

OBJECTIVE

To investigate the effects of early mobilization within 48 h of injury on motor function and walking ability in patients with incomplete cervical spinal cord injury (SCI).

DESIGN

A retrospective observational study.

SETTING

Intensive care unit or high care unit of a university hospital emergency center.

PARTICIPANTS

Of 224 patients with SCI having American Spinal Injury Association impairment scale grades C and D, 158 consecutive patients hospitalized for at least 3 weeks after injury were included.

INTERVENTIONS

Patients were categorized into two groups: an early mobilization group in which patients were mobilized within 48 h of injury and a delayed mobilization group in which they were mobilized after 48 h of injury.

OUTCOME MEASURES

The upper extremity motor score (UEMS), lower extremity motor score (LEMS), and Walking Index for Spinal Cord Injury II (WISCI II) were compared using propensity score matching analysis.

RESULTS

Of the 158 patients who met the eligibility criteria, 32 were matched between the groups. There was a significant difference in the change in LEMS from the initial assessment to the assessment 2 weeks postoperatively in the early mobilization group (median 9 points vs. 3 points, p < 0.05). There were no significant differences in UEMS or WISCI II.

CONCLUSION

Early mobilization within 48 h may improve lower extremity motor function in patients with acute incomplete cervical SCI.
