Does threshold nighttime electrical stimulation benefit children with spina bifida? A pilot study.

Area of Science:

• Pediatric Neurology
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Electrical stimulation is a known treatment for muscle weakness.
• Traditional methods cause discomfort in children.
• Nighttime threshold electrical stimulation is better tolerated and improves strength in various conditions.

Purpose of the Study:

• To determine if nighttime threshold electrical stimulation improves strength and function in children with myelomeningocele.

Main Methods:

• A pilot study prospectively followed 15 children with myelomeningocele as their own controls.
• Participants used a stimulator on weak muscles during sleep, six nights weekly.
• Assessments included muscle strength, sensation, and function (Functional Independence Measure for Children) at 3-month intervals up to 12 months.

Main Results:

• Only 7 of 15 subjects completed 9 months; none finished 12 months.
• The primary complaint was the treatment schedule's intensity relative to benefits.
• Small gains were observed in muscle strength, gait, and bowel continence, but no functional improvements.

Conclusions:

• Threshold electrical stimulation yielded modest improvements in muscle strength for children with myelomeningocele.
• Current treatment schedules are impractical for this patient population.
• Further research is needed to optimize treatment protocols.
