Jeremy Crenshaw, associate professor of KAAP, found his love for biomechanics a little sooner — as a junior in college, studying to be a physical therapist.
“Biomechanics intersects with engineering, physics, biology, kinesiology, and even physical therapy,” Crenshaw said. “Many students are not aware that this area of science is useful for those pursuing a clinical career.”

"Biomechanics is this area of science, it's a combination of engineering, physics, biology, kinesiology, and rehabilitation sciences such as physical therapy," UD Associate Professor of Kinesiology and Applied Physiology Jeremy Crenshaw said. "It's a chance to introduce them to an area of STEM that they're not aware of, science and technology that they haven't seen and get them excited about different career opportunities."
Protect yourself from slips and falls this Winter
Consumer Reports online

The icy ground outside your door, on sidewalks, and in parking lots can make winter a treacherous time. And the older you get, the more difficult it can be to recover from slips and falls, says Jeremy Crenshaw, PhD, an associate professor of kinesiology and applied physiology at the University of Delaware in Newark.
Enlighten Me: UD professors team up on cerebral palsy research
Delaware Public Media online
2019-03-08
One of the many research projects being funded is a cooperative effort between the University of Delaware and Nemours to reduce falls and enable physical activity in children with cerebral palsy.
And for this week’s Enlighten Me, Delaware Public Media’s Nick Ciolino recently sat down with UD researchers Curtis Johnson and Jeremy Crenshaw to discuss how they are combining their individual studies to reach that goal.
UD research: Practicing falling may help prevent it
Bay to Bay News online
2018-01-21
Jeremy Crenshaw, Ph.D., an assistant professor in UD’s Department of Kinesiology and Applied Physiology, has been heading up the lab since 2014. The general advice Mr. Crenshaw has for walking in icy conditions is: shuffling and take short steps if the ground is slippery, always using handrails, avoiding slopes, not carrying anything so your hands remain free and break your fall with your hands if you’re unlucky enough to lose your balance. He notes that landing on your hands increases the likelihood of fracturing your wrists, but it decreases the chance you’ll fracture your hip, which is a far more serious injury. Tai chi, a form of martial arts exercise, has also been known to help limit and reduce certain types of falls.

Susceptibility to walking balance perturbations in young adults is largely unaffected by anticipation
Human Movement Science2023
Despite progress in understanding the mechanisms governing walking balance control, the number of falls in our older adult population is projected to increase. Falls prevention systems and strategies may benefit from understanding how anticipation of a balance perturbation affects the planning and execution of biomechanical responses to mitigate instability. However, the extent to which anticipation affects the proactive and reactive adjustments to perturbations has yet to be fully investigated, even in young adults. Our purpose was to investigate the effects of anticipation on susceptibility to two different mechanical balance perturbations – namely, treadmill-induced perturbations and impulsive waist-pull perturbations.
A novel method to quantify individual limb contributions to standing postural control
Gait & Posture2023
Background
Understanding individual limb contributions to standing postural control is valuable when evaluating populations with asymmetric function (e.g., stroke, amputations). We propose a method of quantifying three contributions to controlling the net anteroposterior center of pressure (CoP) during quiet standing: CoP moving under left and right limbs and weight shifting between the two limbs.
Research question
Can these contributions to standing postural control be quantified from CoP trajectories in neurotypical adults?
Association Between Collision Sport Career Duration and Gait Performance in Male Collegiate Student-Athletes
The American Journal of Sports Medicine2022
Background:
Investigations of estimated age of first exposure to repetitive head impacts from collision and contact sports have shown no associations with neurocognitive or neurobehavioral function at the collegiate level, but the effect of career duration may be a more comprehensive factor. Understanding whether longer career duration influences gait performance would provide insights into potential neurological impairment.
Purpose:
To examine the relationship between career duration of collision sports and single/dual-task gait performance in collegiate student-athletes.
Knee biomechanics and contralateral knee osteoarthritis progression after total knee arthroplasty
Gait & Posture2022
Background
Despite the success rate of Total Knee Arthroplasty (TKA), many patients undergo contralateral TKA. It is possible that altered gait mechanics after unilateral TKA play a role in the progression of contralateral OA progression.
Research question
The purpose of this study was to identify biomechanical predictors of radiographic OA progression in the contralateral (non-surgical) knee after unilateral (primary/initial) TKA. In addition, this study quantified for patients who had contralateral OA progression.
Outdoor walking exhibits peak ankle and knee flexion differences compared to fixed and adaptive-speed treadmills in older adults
BioMedical Engineering OnLine2021
Background
Walking mechanics recorded with a traditional treadmill may not be the same as the mechanics exhibited during activities of daily living due to constrained walking speeds. Adaptive-speed treadmills allow for unconstrained walking speeds similar to outdoor walking. The aim of this study was to determine differences in kinematic walking parameters of older adults between adaptive-speed treadmill (AST), fixed-speed treadmill (FST) and outdoor walking. We hypothesized that self-selected walking speed (SSWS) during AST walking and outdoor walking would increase compared to FST walking. Furthermore, we hypothesized that AST walking and outdoor walking would increase peak knee flexion, hip flexion, and ankle plantarflexion angles compared to FST walking independent of walking speed changes.
