Objective
Development of EMG based real time control of muscle stimulators for the enhancement of human function.
The project aims to increase the performance, application and success of neuromuscular stimulation in aiding the rehabilitation of disabled people in the community. The programme of work will initially involve a detailed survey of clinicians and end users of functional electrical stimulation across Europe, leading to a comprehensive technical programme bringing the latest technologies and signal processing techniques to bear on stimulator and transducer design and application.
Technical Approach : Technical deliverables from the project will include : - Self optimising stimulation electrode arrays, miniature composite stimulation/electrode units, more efficient stimulator power stages, real time processing and feature extraction of EMG artefacts, active EMG measurement electrodes and multi-function re-configurable portable stimulators. A main goal is to realise true interactive control of stimulator parameters to match required function. In order for intermittent 'listening' to EMG signals from muscles to be activated, their coactive synergists or antagonists will be employed to establish the best sources for feedback signals, in addition to input from position or pressure devices.
In addition, the project will undertake full mapping of stimulation and EMG measurements sites for the human body, together with an analysis of the effects of stimulation wave form shape, level and duration on the induced muscle response. A major clinical trial of devices developed will be undertaken in Europe.
Impact and Expected Results : In the first instance the project will produce : Improved designs for miniature power efficient programmable electrical stimulators for body worn use; Active electrode EMG measurement devices for highly sensitive EMG recording; Improved force and position sensors for the measurement and subsequent control of joint and limb movement; Optimised stimulation wave form parameters for more selective, less tiring external stimulation.
The longer term goal is a stimulation system driven by EMG and transducer based sensors to provide more natural, more sustainable movement and function for the user. The work could provide benefit in terms of rehabilitation to over 16% of the population of the European community (simple single limb prosthetics - approximately 4% of the European population; chronic disabling conditions, MS, stroke etc. - around a further 10%; those with complex and multiple handicap - estimated at 2%).
