Study design: Retrospective, quality improvement project.
Objective: This study explores the effect of functional electrical stimulation (FES) on gait parameters in Icelandic citizens with foot drop caused by upper motor neuron (UMN) lesions.
Methods: Participants were 29 individuals with foot drop that received FES treatment at the National Hospital between 2011 and 2019. The recording of baseline data was limited. It was followed by data collection from four evaluations over approximately a 28-week period on the following: 10-meter Walk test, 6-minute walk test, usage data, complications data, and reasons for continued or discontinued treatment. The analysis included descriptive (that included the reporting of minimal clinically important difference (MCID) responders) and a Mixed model analysis.
Results: The participants’ diagnoses were primarily stroke and multiple sclerosis (MS). No statistically significant differences were found for the average gait velocity changes between evaluations. There were, however, participants that reached their MCID values. Largest amount of MCID responders with FES (eight) and without FES (five) were recorded at approximately 21-weeks and 28-weeks of treatment. Largest amount of orthotic effect MCID responders was recorded at approximately 14-weeks of treatment (ten MCID responders). Stroke MCID responders were evident in almost all velocity evaluations, whereas MS MCID responders were primarily represented in the orthotic effect. Mixed model analysis indicated a significant orthotic effect. Post hoc analysis confirmed that the effect was only significant in the first three evaluations. No change was found in 6MWT performance and no correlation was found between device usage and 10mWT. More than half of participants reportedly continued using FES device after last evaluation. Many analyses were low-powered due to missing data.
Conclusion: The main findings of this quality improvement study suggest that some patients with foot drop due to UMN lesions may benefit from FES treatment in agreement with existing literature.
