“The Science of pain is complex and its assessment subjective, leading to bias and health inequality. Now, researchers are searching for a reliable, objective measure of pain.”

Overview
PainTrace® Multi-species Neurobiosignal is an Actionable Outcome Measure That Objectively Quantifies Acute and Chronic Pain In Many Use Cases Such As:
- Treatment Efficacy
- Orthopedic Exam
- Perioperative Assessment
- Nociceptive, Neuropathic, Somatic, Visceral, Trigeminal

- Treatment Efficacy
- Orthopedic Exam
- Perioperative Assessment
- Nociceptive, Neuropathic, Somatic, Visceral, Trigeminal
-
PainTrace is an objective neurobiosignature correlated with human self-reported pain
-
PainTrace differentiates acute and chronic pain, measuring both magnitude and duration of the pain experience
-
Quantify the individual experience of pain with an objective outcome measure to strengthen research conclusions
- The PainTrace Baseline measures chronic pain. Positive values indicate degree of non-painful state and increasing negative values indicate mild, moderate, and severe chronic pain state.
- PainTrace Acute Peaks quantify response to orthopedic examination, activity, palpation. Peak amplitudes are highlighted by intensity.
YELLOW = MILD
ORANGE = MODERATE
RED = SEVERE

Case Examples
Shoulder arthritis: chronic pain and locates acute pain
Osteoarthritis: Pre- and Post-NSAIDs
Chronic Pain with NSAIDs for 18 Weeks
Effect on PainTrace® Baseline values, indicating chronic pain state, with the administration of NSAIDs over 18 weeks
- NSAID’s were administered over 18 weeks. PainTrace Baseline was monitored to evaluate treatment efficacy to mitigate chronic pain
- NSAID administration initiated March 7
- PainTrace Baseline Average denoted chronic pain (-6.43) prior to NSAID therapy; March 4 – 6
- Improvement to a pain-free PainTrace Baseline Average (+3.23) while administering NSAID; April 1 – July 21
- Measure of efficacy using Treatment Delta = 9.66
- After stopping NSAIDs chronic pain returned; PainTrace equals -1.3- on November 3

“To better understand chronic pain, we first need to address the problem of how to evaluate the severity of pain.”

Challenges
90% of Pain Studies Fail
-
“The overall probability of successful development of all pain medications from phase 1 to approval is 10.4%.” and success in the development of new therapeutics with low abuse potential is even lower at 4.7%.
(Estimates of Probabilities of Successful Development of Pain Medications: An Analysis of Pharmaceutical Clinical Development Programs from 2000 to 2020; Anesthesiology)
Costly Studies to Perform
-
Pain studies cost 1.6 times more than other studies.
-
Pain and anesthesia trials rank in the 3 most expensive by therapeutic area for phase 2, 3 and 4.
