Effects of orthotic therapeutic electrical stimulation in the treatment of patients with paresis associated with acute cervical spinal cord injury: a randomized control trial.

STUDY

DESIGN

A randomized controlled trial.

OBJECTIVES

To determine the effects of orthotic therapeutic electrical stimulation (TES) on the hand in patients with paresis associated with acute cervical spinal cord injury.

SETTING

Spinal Injuries Center, Fukuoka, Japan.

METHODS

The study included patients treated for spinal cord injuries (Frankel classification, grades B and C) at our institution within 1 week post injury between May 2011 and December 2014. The patients were allocated randomly to TES and control groups at the time of admission and underwent TES+conventional training or conventional training alone, respectively. Both hands of each patient were treated in the same way. The primary outcome was total passive motion (TPM) of the fingers (degrees). The secondary outcomes were edema (cm) and the upper-extremity motor scores of the International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI). After randomization, outcomes were assessed at 1 week, 1 month and 3 months post injury in both groups.

RESULTS

Twenty-nine individuals were assessed at 3 months (15, TES; 14, control). There were no significant between-group differences for TPM of the fingers, edema and upper-extremity motor scores at 1 week, 1 month and 3 months after injury, although TPM of the fingers tended to be lower in the control group.

CONCLUSIONS

It is unclear from the results of this study whether TES has a therapeutic effect on TPM, edema or the upper-extremity motor score of the ISNCSCI. The results of this study provide useful data for future meta-analyses.
