Singularity Characteristics of Needle EMG IP Signals

Evaluating Spatial Characteristics of Upper-Limb Movements from EMG Signals

Stroke is a major cause of disability, usually causing hemiplegic damage on the motor abilities of the patient. Stroke rehabilitation seeks restoring normal motion on the affected limb. However, ‘normality’ of movements is usually assessed by clinical and functional tests, without considering how the motor system responds to therapy. We hypothesized that electromyographic (EMG) recordings could...

Needle EMG guidance for injection of botulinum toxin. Needle EMG guidance is useful.

Botulinum toxin (BTX) is used increasingly in neurologic practice. Needle electromyographic (EMG) analysis of muscles in disorders treated with BTX is often useful in diagnosis, assessing treatment response, and searching for denervation when neutralizing antibodies are suspected. These are important uses of needle EMG. Although needle EMG guidance for injection of BTX is an accepted technique,...

Decomposition of surface EMG signals.

This report describes an early version of a technique for decomposing surface electromyographic (sEMG) signals into the constituent motor unit (MU) action potential trains. A surface sensor array is used to collect four channels of differentially amplified EMG signals. The decomposition is achieved by a set of algorithms that uses a specially developed knowledge-based Artificial Intelligence fr...
