Student-Faculty Research - College of Physical Therapy

For older adults, performing activities of daily living (ADLs) requires generating short bursts of energy anaerobically.1 The current gold standard for measuring anaerobic threshold (AT) is the Wingate Anaerobic Test, which requires a specialized bicycle. While many tests exist to assess fall risk and submaximal endurance, there is an absence of accessible clinical tools for measuring anaerobic threshold. Measuring AT is an important predictor of an older adult’s ability to perform ADLs safely, allowing physical therapists to tailor interventions to improve function and quality of life.

Student-Faculty Research - College of Physical Therapy

Falls account for >$50 billion of medical spending in 2015 (CDC). Real-time haptic feedback shows promise at reducing static standing COM sway (Meszaros, 2019). Pilot data variability suggests that some haptic-wearers ‘over-correct’ (unnecessarily reducing available degrees of freedom), when haptic correction is perceived as ‘a mistake. Does over-correction reduce multi-segment control and impair sway stability (Hsu, Scholz, et al. 2007)?

Factors Affecting Peak Effort In Max Effort Tests, Amanda Pardue, Michael Forster, Taylor Kopecky, Zoralei Dayley, Jeff Houck, Rebecca Dobler

Student-Faculty Research - College of Physical Therapy

In Vivo Behavior Of The Soleus Muscle During Various Activities In Persons Post-Stroke, Madison Swaney, Molly Carter, Mitchell Mckinley, Joshua Nelson, Robin Dorociak, Tyler Cuddeford

Student-Faculty Research - College of Physical Therapy

Current protocols for post stroke populations consists of inconsistent and outdated interventions that target less functional strength training through heavier and slower movements. Current research displays a 90/10 principle displaying the tendon as the primary power absorber and generator during ballistic and cyclic movements, supported by a primarily isometric muscle activation. Power generation is key for walking. High angular velocity needed during the gait cycle to be able to produce and absorb power rapidly. Ballistic training requires the perfect tradeoff between speed and force to generate and train populations targeting power absorption and output with greater tendon activity. Therefore, current …
