Prolonged electrical stimulation causes no damage to sacral nerve roots in rabbits

Area of Science:

• Neuroscience
• Regenerative Medicine
• Urology

Background:

• Sacral nerve root stimulation shows promise for restoring bladder function.
• Potential long-term effects of anode block electrical stimulation on sacral nerve roots require investigation.

Purpose of the Study:

• To evaluate the impact of chronic anode block electrical stimulation on the structural integrity and cellular health of sacral nerve roots in a rabbit spinal cord injury model.

Main Methods:

• A T9-10 spinal cord transection model was established in New Zealand white rabbits.
• Rabbits received both short-term and chronic anode block electrical stimulation.
• Nerve cell structure and apoptosis-related protein expression (Bax, Caspase-3, Bcl-2) in sacral nerve roots were analyzed.

Main Results:

• No structural changes were observed in sacral nerve root neurons after electrical stimulation compared to controls.
• There were no significant differences in the expression of apoptosis-related proteins (Bax, Caspase-3, Bcl-2).

Conclusions:

• Neurons in the sacral nerve roots demonstrate tolerance to chronic anode block electrical stimulation.
• Findings suggest that long-term electrical stimulation is safe for sacral nerve roots in this model.
