Facilitation of Dependent Transfers with Functional Neuromuscular Stimulation – A Computer Simulation Study

This study explores how functional neuromuscular stimulation (FNS) can help people with spinal cord injuries (SCI) during assisted lifts. FNS uses electrical stimulation to activate paralyzed muscles. The researchers used computer simulations to model patient lifts with and without FNS. They also estimated the spinal compression experienced by caregivers during these lifts. The simulations suggest that FNS can reduce the amount of force required from caregivers, potentially lowering their risk of back injury.

• 1
  Simulation without muscle activation predicted caregiver spinal compression approximately 1.3x the NIOSH recommended ‘Action Limit’.
• 2
  Simulations with two unique patterns of muscle activation both predicted caregiver spinal compressions below NIOSH recommendations.
• 3
  Activating knee, hip, and trunk extensors decreased caregiver spinal compression to levels similar to quiet standing.
