Patients' perceptions of the Odstock Dropped Foot Stimulator (ODFS)

Abstract

Objective: To determine the perceived benefit, pattern and problems of use of the Odstock Dropped Foot Stimulator (ODFS) and the users' opinion of the service provided. Design: Questionnaire sent in a single mailshot to current and past users of the ODFS. Returns were sent anonymously. Setting: Outpatient-based clinical service. Subjects: One hundred and sixty-eight current and 123 past users with diagnoses of stroke (CVA), multiple sclerosis (MS), incomplete spinal cord injury (SCI), traumatic brain injury (TBI) and cerebral palsy (CP). Intervention: Functional electrical stimulation (FES) to correct dropped foot in subjects with an upper motor neuron lesion, using the ODFS. Main outcome measures: Purpose-designed questionnaire. Results:• Return rate 64% current users (mean duration of use 19.5 months) and 43% past users (mean duration of use 10.7 months). • Principal reason cited for using equipment was a reduction in the effort of walking. • Principal reasons identified for discontinuing were an improvement in mobility, electrode positioning difficulties and deteriorating mobility. • There were some problems with reliability of equipment. • Level of service provided was thought to be good. Conclusion: The ODFS was perceived by the users to be of considerable benefit. A comprehensive clinical follow-up service is essential to achieve the maximum continuing benefit from FES-based orthoses.
