Study Overview
Brief Summary
The purpose of this small-scale exploratory study is to bridge the knowledge gap between the bench testing and the design of potential future confirmative studies. Identifying and evaluating MicroEMG measurement parameters in this exploratory manner is a necessary step to evaluate its usability and design, and determine whether the microEMG system may be suitable for in-house use after further confirmative testing.
Detailed Description
About this study We have developed a completely new multi-electrode electromyography system (MicroEMG) that we want to test in this study. It records muscle activity from multiple recording points in the muscle at once. We believe that this will increase the sensitivity of the technique in diagnosing muscle disease, reduce the time taken, and be more comfortable for patients. However, to prove whether this is the case we first need to understand the how the recorded signals of the new MicroEMG look like in different patient groups.
Background:
Why are we doing this study?
Electromyography (EMG) is an essential diagnostic test for nerve and muscle diseases. Cells in the muscle generate electric potentials when they are activated. This activity can be measured by the EMG. Based on those 'patterns', experts can detect medical abnormalities, such as muscle or nerve disorders. EMG involves inserting a thin metal needle electrode through the skin into a muscle. It records changes in the pattern of electrical signals produced by the muscle fibres. In conventional EMG only a single recording surface at the tip of the needle is used and therefore only small part of muscle can be examined.
We developed a new EMG device called MicroEMG. It uses a novel type of electrode that can examine the muscle in more detail. As it records activity from several different points at the muscle at once it can produce an electrical image (rather than an abstract signal). This way a large volume of muscle can be recorded simultaneously with less movement and discomfort for the patient.
