Backed by biomechanics research
Softer impact. Energy returned. Less effort.
Since 1989, research teams at Brown, Penn State, the University of Auckland, BYU and Inje University have tested spring-loaded crutches with force plates, motion capture and muscle sensors. The results point the same way.
- 22% Smaller shock waves on ground impact Parziale & Daniels, 1989
- 33% Slower force build-up at the crutch tip Segura & Piazza, 2007
- 9.6% More forward energy at the end of each step Bateman et al., BYU
- 15% Less calf muscle effort while walking Kang et al., 2016

The Mechanical Performance of Ambulation Using Spring-loaded Axillary Crutches
Parziale & Daniels · Am. J. Phys. Med. & Rehab., 1989 · Brown University
Spring-loaded crutches produced 22% smaller shock waves at initial contact and 24% lower peak stresses, with better reported endurance and comfort.
-
Mechanics of Ambulation With Standard and Spring-Loaded Crutches
Segura & Piazza · Archives of Phys. Med. & Rehab., 2007 · Penn State
The rate of force build-up at the crutch tip dropped 33% and total ground-force impulse fell 13–26%, changes the authors linked to lower overuse-injury risk.
-
Biomechanical Evaluation of an Innovative Spring-Loaded Axillary Crutch Design
Zhang, Liu, Xie & Liger · Assistive Technology, 2011 · University of Auckland
Standard crutches showed two sharp force peaks per step; the spring design produced one smoother peak, with stored spring energy helping move the user forward.
-
Mechanical Efficiency of Walking with Spring-loaded Axillary Crutches
Zhang, Beaven, Liu & Xie · Assistive Technology, 2013 · University of Auckland
Mechanical efficiency was significantly higher with spring-loaded crutches: more walking work for the same metabolic effort.
-
An Evaluation of Mechanical Energy Transfer During Spring-loaded and Traditional Crutch Ambulation
Bateman, Seeley, Roggia, Larson & Draper · Human Performance Research Center, BYU
Spring-loaded crutches delivered 5% higher forward velocity and 9.6% more forward kinetic energy at the end of each crutch step.
-
A Biomechanical Evaluation of a Novel Mobile Walking Device
Bateman & Seeley · Journal of Undergraduate Research, BYU, 2013
Comparing the Millennial spring-assisted crutch with a traditional crutch, the team concluded the spring-assisted design decreases energy expenditure during walking.

Effects of Spring-Loaded Crutches on Gastrocnemius Activity and Upward Displacement of the Body During Gait
Kang, Oh & Yang · Journal of Physical Therapy Science, 2016 · Inje University
Calf muscle activity dropped significantly while the body rose higher with each step: the spring did more of the lifting so the leg did less.
Compared with standard crutches in controlled lab testing. Studies are shared for education and are not medical advice.
