Is functional electrical stimulation effective in improving walking in adults with lower limb impairment due to an upper motor neuron lesion? An umbrella review.

PURPOSE: To conduct an umbrella review of systematic reviews on functional electrical stimulation (FES) to improve walking in adults with an upper motor neuron lesion. METHODS: Five electronic databases were searched, focusing on the effect of FES on walking. The methodological quality of reviews was evaluated using AMSTAR2 and certainty of evidence was established through the GRADE approach. RESULTS: The methodological quality of the 24 eligible reviews (stroke, n = 16; spinal cord injury (SCI), n = 5; multiple sclerosis (MS); n = 2; mixed population, n = 1) ranged from critically low to high. Stroke reviews concluded that FES improved walking speed through an orthotic (immediate) effect and had a therapeutic benefit (i.e., over time) compared to usual care (low certainty evidence). There was low-to-moderate certainty evidence that FES was no better or worse than an Ankle Foot Orthosis regarding walking speed post 6 months. MS reviews concluded that FES had an orthotic but no therapeutic effect on walking. SCI reviews concluded that FES with or without treadmill training improved speed but combined with an orthosis was no better than orthosis alone. FES may improve quality of life and reduce falls in MS and stroke populations. CONCLUSION: FES has orthotic and therapeutic benefits. Certainty of evidence was low-to-moderate, mostly due to high risk of bias, low sample sizes, and wide variation in outcome measures. Future trials must be of higher quality, use agreed outcome measures, including measures other than walking speed, and examine the effects of FES for adults with cerebral palsy, traumatic and acquired brain injury, and Parkinson's disease.

"Functional electrical stimulation (FES) impacted on important aspects of my life": a qualitative exploration of chronic stroke patients' and carers' perceptions of FES in the management of dropped foot.

Our purpose was to explore the impact of functional electrical stimulation (FES), as applied in the management of dropped foot, on patients with chronic stroke and their carers. A qualitative phenomenological study was undertaken. Participants were recruited from the Lothian FES clinic. Data were collected by using semistructured face-to-face interviews and analysed by using the framework of interpretative phenomenological analysis (IPA). Thirteen patients and nine carers consented to participate in the study. The overarching theme that emerged from the data was that "FES impacted on important aspects of my life." Four subthemes were identified: 1) "Walking with FES is much better"; 2) "FES helped regain control of life"; 3) "Feeling good comes with using FES"; and 4) "FES is not perfect but it is of value." This study provides insights into the perceptions of patients and carers of the impact of FES. These results have implications for clinicians delivering an FES service for the management of dropped foot after stroke.

A mixed methods service evaluation of a pilot functional electrical stimulation clinic for the correction of dropped foot in patients with chronic stroke.

AIM: To undertake a service evaluation of the pilot Lothian functional electrical stimulation (FES) clinic using both quantitative and qualitative methods and clinical practice reflection. BACKGROUND: Clinical guidelines recommend that FES, for the management of dropped foot after stroke, is delivered by a specialist team. However, little detail is provided about the structure and composition of the specialist team or model of service delivery. A pilot Lothian FES clinic was developed to explore the clinical value of providing such a service to stroke patients with dropped foot and identify any service modifications. METHODS: Mixed methods were used to evaluate the service and included quantitative, qualitative and reflective components. Phase 1: Before and after service evaluation of patients attending the FES clinic between 2003 and 2007. Outcomes of gait velocity and cadence were recorded at initial clinic appointment and 6 months after application of FES. Phase 2: Qualitative research exploring patients with stroke and carers' experiences of the FES clinic. Data were collected via semi-structured interviews. Phase 3: A reflection on the service delivery model. PARTICIPANTS: Phase 1: 40 consecutive out-patients with stroke; Phase 2: 13 out-patients with stroke and 9 carers; Phase 3: Three specialist physiotherapists engaged in running the FES clinic. FINDINGS: Statistically significant improvements (p < 0.001) were demonstrated in gait velocity and cadence. Qualitatively, one super-ordinate theme 'The FES clinic met my needs' emerged. Within this were four sub-themes, namely 1. 'Getting to grips with FES wasn't difficult'; 2. 'It's great to know they're there'; 3. 'Meeting up with others really helps' and 4. 'The service is great but could be better'. On reflection, minor modifications were made to the service delivery model but overall the service met user needs. This dedicated FES clinic produced positive physical outcomes and met the needs of this chronic stroke population.
