Functional electrical stimulation for foot drop syndrome: The effect on velocity and gait endurance – preliminary data
Journal Title: Rehabilitacja Medyczna - Year 2013, Vol 17, Issue 3
Abstract
Introduction: Foot-drop is a frequent symptom of the Central Nervous System diseases (CNS) that may cause walking disorder. The primary therapeutic choice for foot-drop disease are the various classical Ankle-Foot Orthoses (AFO). The Functional Electrical Stimulation (FES) of the ankle dorsiflexors muscles was described as quite effective at enhancing balance control and ankle dynamic stability during gait.Aim: The purpose of the study was to assess and consider the effects of FES-application regarding either the gait velocity or the resistance, in patients with foot-drop due to a chronic upper motor neuron lesion. Research project: Before-after study.Material and methods: There were enrolled 20 subjects, with an upper motor neuron lesion which presented foot-drop. Patients were divided randomly into 2 training groups (the FES group, N=10 or the Control Group, N=10). The treatment in the FES group consisted of neuroprosthesis application, for 2h/day, 5 days/weekly, for 3 weeks whereas, in the Control Group patients executed the gait treatment with the help of AFO. In both groups the FES or AFO application was considered as an additional gait training to the individual rehabilitation programme. The participants were assessed by using the 5 – 10 – 20 meters (m) Walking Test and 2 – 6 – 12 minutes (min) Timed Walking Test. Results: A higher degree of gait improvement was noted in subjects from the group which underwent FES treatment, than in those treated with AFO. Regarding the FES group, a statistically significant improvement was demonstrated by patients in tests as follows: 20m p<0.024 and 2min p<0.028; 6min p<0.008; 12min p<0.005, but not in the 5m p<0.079 and 10mt p<0.084 Walking Test. While, in the control group we did not note a statistically significant difference (5m p<0.228; 10m p<0.260; 20m p<0.107 and 2min p<0.474; 6min p<0.575; 12min p<0.477). Conclusions: Despite the limited sample of the patients enrolled, the results are encouraging because the tests demonstrate that FES-treatment could increase walking resistance and distance.
