How does Pact Sense work?

The Pact system uses data collected from the Pact Sense to calculate your Muscle Stiffness Score. Similar to a physical therapist gathering a subjective feeling of your muscles, the Pact system goes a step further, providing objective numbers that can be used to track muscle stiffness over time

Analyzing Muscles with the Pact Sense Scanner

This white paper details how the Pact Sense muscle scanner functions, the technical aspects of what the device is measuring, and the underlying technology that powers the device. Additionally, several research studies verifying the device performance are covered, illustrating applications of the Pact Sense

Muscle Characterization Using System Identification

Pact Sense session graph

This white paper details how Impact Biosystems uses System Identification techniques to measure the mechanical properties of the muscle. With these techniques, Impact can quantify palpation of the muscles and providing meaningful insights to physical therapists and trainers

Pact Scanner Parameters General Overview

There are four parameters that the Pact system uses to characterize the mechanical state of muscle - stiffness, damping, stiffness slope, and damping slope. With these four parameters, Pact can quantify the state of any superficial muscle and the soft tissues around it.
