Gait Studies

Data-Driven Movement Analysis

Quorum uses gait studies to analyze movement, stability, and performance, helping guide continued innovation in prosthetic design.

Walking symmetry can be evaluated through gait analysis, showing how weight and movement are distributed during walking and providing insight into stability.
Ground reaction force analysis examines peak vertical force asymmetry to understand how weight is distributed between the limbs during walking.
“Socket performance can be evaluated through movement analysis, showing how socket fit and adjustability may influence stability and walking mechanics.
Real world mobility research examines how adjustable socket technology performs during everyday movement.

Gait Testing in Motion
