OBJECTIVE

To determine if the bone mineral density loss seen after spinal cord injury (SCI) is reversed by a walking program using the Parastep 1 system.

DESIGN

Before-after trial.

SETTING

Human SCI applied research laboratory.

PARTICIPANTS

Thirteen men and 3 women with thoracic motor- and sensory-complete SCI, mean age 28.8yrs, mean duration postinjury 3.8yrs.

INTERVENTION

Thirty-two functional neuromuscular stimulation (FNS) ambulation training sessions using a commercially available system (Parastep 1). This system consists of a microprocessor-controlled stimulator and a modified walking frame with finger-operated switches that permit the user to control the stimulation parameters and activate the stepping.

OUTCOME MEASURE

Bone mineral density at the femoral head, neck, and Ward's triangle measured using a Lunar DP3 dual-photon densitometer.

RESULTS

No significant change in bone mineral density was found using repeated measures analyses of variance.

CONCLUSIONS

Axial loading combined with muscle stimulation and resistive exercise does not result in significant changes in bone mineral density in persons with complete paraplegia.
