I am grateful to my coauthors, Malin Ramne and Prof. Johan Wessberg, for working with me to develop these measures and ensure their multidisciplinary and translational potential within research and healthcare.

These measures are generalizable and applicable to any application of somatosensory maps, including grid-based and free-hand drawings, resulting in improved pain characterization and better understanding of the needs and progression of patients experiencing pain.
SPD is derived from optimal transport theory, which quantifies differences between two probability distributions or somatosensory maps. The utility of these measures is demonstrated using data from two studies characterizing somatosensory percepts and neuropathic pain drawings.
SPI is inspired by Piper’s law, which describes the phenomenon of incomplete spatial summation wherein changes in pain area do not yield linearly proportional changes in perceived intensity.
In this paper, we propose two unified measures, Somatosensory Percept Intensity (SPI) and Somatosensory Percept Deviation (SPD), to overcome these limitations and to more accurately quantify longitudinal changes in sensation and pain.
Unified Measurs of Somatosensory Percept Intensity & Similarity. Pain maps and somatotopic maps can take on many forms, making comparisons challenging. We propose novel measures quantifying & unifying the intensity and similarity of somatosensory percepts. These novel measures are generalizable and applicable to any somatosensory map.

When comparing two #sensory or #pain maps, how does one quantify their similarity in intensity, area, and location? Current methods fail to account for the interaction between these characteristics.
Epimysial electrodes may be better suited for larger muscles and for predicting gross hand movements.
Intramuscular electrodes may be better suited for smaller muscles and predicting finger movements.

A graphic of the musculature and nerves in an amputated arm with an osseointegrated implant extending from the skin. Title: "Comparing Implantable Epimysial and Intramuscular Electrodes for Prosthetic Control" Authors: Eric J Earley, Morten B Kristoffersen, Max Ortiz-Catalan Caption: Case Series - Which electrodes are better suited for prosthesis control? Epimysial electrodes may be better suited for larger muscles and predicting gross hand movements. Intramuscular electrodes may be better suited for smaller muscles and predicting finger movements.
When using implantable #electrodes, which are best for #prosthetic control?🦾
Our study published in Frontiers In Neuroscience compares epimysial and intramuscular electrodes to see when each should be considered.

Hello! I'm a bionics researcher interested in how neuromuscular and skeletal interfaces for prosthetic arms and legs change the way that people with amputations use, feel, and think about their prostheses.
I'm passionate about #SciComm, photography, and music, and consider myself a serial dabbler 😎
