Single needle multi
scanning EMG
is a research technique that provides a new useful way to
obtain
several motor unit potentials from a single scan. The main issue of this approach is that the
solutions
are
numerous, most of them being invalid solut
ions presenting only
needle
cannula
pattern
or spurious
signals linked together.
From the above, the main purpose of this work is to define and test algorithms that are able to estimate
the spatial limits of the a
ctive region of a motor
unit
potential
and
use it to distinguish among valid
and invalid solutions. The dataset is provided by single-needle multiscannig-EMG simulations that
allow to have a wide variability of records
together with the ground truth limits.
The proposed
algorithms have to achieve
two main tasks: discard the invalid signals and set the limits if a valid
region of motor unit activity is found.
Three different methods are proposed,
described, and evaluated
in this work. Results are analyzed for
every method and compared between them.
Considering only the cases in which a good overlapping
with ground truth is available, all of the three algorithms are robust and show an appreciable level of
accuracy in their estimation. When comparing them, two
of the algorithms show a
consistent
unbias
edness and a lower error variance than the third one. [--]
