Patients with hemiplegia who used a functional electrical stimulation device for isolated foot drop showed no significant functional differences during gait, according to results presented at the Association of Children’s Prosthetic-Orthotic Clinics Annual Meeting, here.

Broomfiled, Colorado – David E. Westberry MD and colleagues at Shriners Hospital for Children in Greenville SC, conducted a retrospective review of four patients who underwent motion analysis studies during ambulation with and without the WalkAide, an active functional electrical system (FES) device. Patients ranged in age from 12 years to 18 years.
All of the patients completed motion lab assessments while wearing the device. Two patients had spastic hemiplegia, one patient had asymmetric diplegia and one patient had hemiparesis secondary to hemispherectomy. Prior interventions included a posterior leaf spring orthosis for one patient, plantar flexor Botox injection for one patient and plantar flexor lengthening in two patients. Patients used the FES device for an average of 19.3 months prior to gait lab assessment.
Results of the study showed no significant functional benefits for any of the patients. One patient showed improvement in peak ankle dorsiflexion during the swing phase when the FES was in place and active, but showed no improvement during the stance phase.
“[Among] functional results, there were no differences in walking speed, stride length or cadence,” Westberry said.
Despite these results, all four patients preferred the FES device compared with traditional ankle foot orthoses (AFOs).
“In subjective results, there was a preference for the WalkAide over the traditional AFOs and the kids did appreciate the benefit of utilizing the device,” Westberry said. “The outcomes were variable and may not be sufficient to justify the clinical use, but the overall, patient experience was favorable.”
