Neurogenic drop foot may be caused by central or peripheral lesions of the nervous system. Depending on whether the first or second motor neuron is damaged, a flaccid or spastic drop foot develops. Spastic drop foot persists as a residual long-term complication after stroke in about 14 % of patients. Various conservative and surgical treatment options are available. This article is based on a systematic literature review for medical evidence of functional electrical stimulation (FES) with the keywords "functional electrical stimulation AND drop foot" and "functional electrical stimulation AND gait AND stroke" in PubMed and Cochrane databases. Randomised controlled trials and cohort studies of the past 10 years were selected according to specific criteria. Additionally, four guidelines were included. Current guidelines provide little guidance for practical treatment and fail to give due consideration to new surgical procedures such as neural implants. In 18 randomised controlled trials on FES in stroke patients with drop foot, the FES-treated population showed either significant superiority or non-inferiority versus control. Two cohort studies confirmed significant improvements by FES. The analysis demonstrates the importance of considering causes and severity of drop foot as well as patients' pre- and post-operative conditions for choosing treatment options. For active, high-demand patients, neural implants are valuable treatment options.

“…Functional electrical stimulation (FES) is a successful complement to foot drop during walking in persons with chronic stroke [16]. By supplementing the foot drop, excessive knee flexion can be prevented at the initial swing phase [17].…”

“…By supplementing the foot drop, excessive knee flexion can be prevented at the initial swing phase [17]. However, Tan et al [16] reported that applying FES to the ankle alone cannot compensate for problems occurring in the hip. In functional training, it is more effective to apply FES to the anterior tibialis and the Gm muscle rather than the anterior tibialis muscle alone during gait training [18].…”

The aim of this research was to investigate the effects of functional electrical stimulation (FES) applied to the gluteus medius (Gm) and tibialis anterior (TA) during stair climbing in persons with stroke compared to FES applied to the TA only during stair climbing, and during stair climbing without FES in persons with stroke. Design: Cross-sectional study. Methods: Twenty subjects with stroke participated in this study. Subjects were included if: 1) they were diagnosed as stroke at least 6 months before; 2) had Mini Mental State Examination-Korean score of 24 or higher; 3) were able to climb a flight of 10 stairs independently (with or without walking aid). The patients walked 10 stairs 3 times with FES applied to the Gm and TA, only TA, or no FES. There was a 1-minute rest period between each bout. The assessments were made using the Timed Up & Down Test and the Wii Balance Board. Results: Stair climbing with FES applied to the Gm and TA was significantly faster than stair climbing with FES applied to the TA only and without FES (p<0.05). Stair climbing with FES applied to the Gm and TA exhibited significantly greater sway velocity than stair climbing without FES (p<0.05). However, maximal sway distances were not significantly different between groups. Conclusions: Stair climbing with FES applied to the Gm and TA can be an important component of a rehabilitation program for improving stair climbing ability in persons with stroke.

“…Over the last several decades Functional Electrical Stimulation (FES) has proven to be a useful tool in rehabilitation [1][2][3]. FES can help with basic muscle training [4], can initiate or amplify motion, and can provide sensory feedback [5]. Compared with a passive orthosis, FES does not limit the range of motion or the use of muscles [6].…”

Background: FES (Functional Electrical Stimulation) neuroprostheses have long been a permanent feature in the rehabilitation and gait support of people who had a stroke or have a Spinal Cord Injury (SCI). Over time the well-known foot switch triggered drop foot neuroprosthesis, was extended to a multichannel full-leg support neuroprosthesis enabling improved support and rehabilitation. However, these neuroprostheses had to be manually tuned and could not adapt to the persons' individual needs. In recent research, a learning controller was added to the drop foot neuroprosthesis, so that the full stimulation pattern during the swing phase could be adapted by measuring the joint angles of previous steps. Methods: The aim of this research is to begin developing a learning full-leg supporting neuroprosthesis, which controls the antagonistic muscle pairs for knee flexion and extension, as well as for ankle joint dorsi-and plantarflexion during all gait phases. A method was established that allows a continuous assessment of knee and foot joint angles with every step. This method can warp the physiological joint angles of healthy subjects to match the individual pathological gait of the subject and thus allows a direct comparison of the two. A new kind of Iterative Learning Controller (ILC) is proposed which works independent of the step duration of the individual and uses physiological joint angle reference bands. Results: In a first test with four people with an incomplete SCI, the results showed that the proposed neuroprosthesis was able to generate individually fitted stimulation patterns for three of the participants. The other participant was more severely affected and had to be excluded due to the resulting false triggering of the gait phase detection. For two of the three remaining participants, a slight improvement in the average foot angles could be observed, for one participant slight improvements in the averaged knee angles. These improvements where in the range of 4°at the times of peak dorsiflexion, peak plantarflexion, or peak knee flexion. Conclusions: Direct adaptation to the current gait of the participants could be achieved with the proposed method. The preliminary first test with people with a SCI showed that the neuroprosthesis can generate individual stimulation patterns. The sensitivity to the knee angle reset, timing problems in participants with significant gait fluctuations, and the automatic ILC gain tuning are remaining issues that need be addressed. Subsequently, future studies should compare the improved, long-term rehabilitation effects of the here presented neuroprosthesis, with conventional multichannel FES neuroprostheses.
