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Current protocols for post stroke populations consists of inconsistent and outdated interventions that target less functional strength training through heavier and slower movements.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 …

Is Sway-Referenced Haptic Assistance Sensitive To Perceptual Context, Andrew Meszaros, Robin Dorociack, Peter Jang, Tanner Lehr, Bayli Mohl

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)?

Imu And Markerless Technology In Gait Analysis: Clinical Lessons, Jessa Barendse, Trevor Nannini, Joanna Zuckerman, Tess Swake, Robin Dorociak, Peter Jang, Andrew Meszaros

Student-Faculty Research - College of Physical Therapy

- Haptic feedback refers to the external vibratory cue that is activated by data picked up by the haptic device, Inertial Measurement Unit (IMU) (Figure 1), which senses joint position.

- Position-driven haptic touch input can modify movement in real-time (Meszaros, 2019)

- Original goal: to reduce knee hyperextension during gait using a popliteal fossa tactor driven by an IMU-based angle sensor (Sagemotion)

-Concerns arose on the validity of IMU/tactor and markerless motion analysis ❏ Are these algorithm-based data technologies clinic-ready?

- Does Sagemotion IMU fire the tactor at the actual knee angle selected in its software?

- Can markerless …

Hamstring Tendons Don’T Lie #Eccentricsdontexist, Alec Espinoza, Chris Garcia, Enoch Ho, Ian Rousseau, Joel Centeno, Robin Dorociak, Tyler Cuddeford

Student-Faculty Research - College of Physical Therapy

Research done on the plantarflexor MTU have shown the degree of achilles tendon and muscle fascicle shortening/stretching is specific to demands of the activity. To expand on this principle, we wanted to explore if a similar relationship exists with the Biceps Femoris MTU. We predict that the biceps femoris (long head) muscle tendon unit (MTU) will behave similarly to the Achilles tendon complex exhibiting the 80/20 principle during dynamic activities (jogging, walking) and the muscle fascicle will lengthen more than the MTU during stationary exercise (Nordic hamstring curls, Romanian deadlifts).

Fatigue Changes Biomechanical Variables In Drop Vertical Jump Performance In Competitive Basketball Players, Isabella Bruno, Caroline Linardos, Michala Rennels, Kristina Williams, Robin Dorociak, Jaydee Romick, Jason Brumitt

Student-Faculty Research - College of Physical Therapy

The drop vertical jump (DVJ) has been used as a tool to identify athletes at risk for injury. Initial studies have suggested an association between biomechanical variables and injury (1); however, subsequent research has demonstrated no relationship (2-4). Evaluating variables in fatigued athletes may help clinicians identify athletes at risk. Advances in motion capture technology now allow for assessment of variables after a fatigue protocol.

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

Challenging older adults to execute peak effort functional tests is not common. A peak effort test pushes patients to the point of not sustaining the task. The Wingate test is a peak effort test that measures the amount of revolutions per second a participant can perform over 30s. Older adults with knee osteoarthritis (OA) may regulate their effort during the Wingate. Alternatively, high exertion during the Wingate test may yield high value in influencing attitudes related to pain and aging. The purpose of this study was to develop themes of what influences peak effort during the Wingate test in participants …

Student-Faculty Research - College of Physical Therapy

Falls are a major health concern among adults ≥65 years as it is the leading cause of injury and injury related death in the United States. Perturbation-based training (PBT) has been shown to reduce rate of falls by 50% and 24 slips has been shown to be optimal. It is unknown whether falls reduction would be greater with one session or spread out over multiple sessions. The purpose of this study was to determine the effects of PBT dosage (12 slips over 2 sessions vs. 24 slips in one session) on falls incidence, fear of falling, and reactive stepping in …

Blood flow restriction training utilizes a tourniquet system to occlude arterial and venous flow while one performs exercises. This training strategy allows one to exercise using loads at a lower percentage of 1RM while experiencing physiological change similar to those achieved when training at a higher percentage of 1RM.

It's Time To (Again) Recognize The Considerable Clinical And Public Health Significance Of Cardiorespiratory Fitness, Leonard A. Kaminsky, Mary T. Imboden, Cemal Ozemek

Faculty Publications - Department of Kinesiology

In this issue of the Journal of the American College of Cardiology, Kokkinos et al5 studied the relationship of both a single CRF value, and change in CRF, with all-cause mortality in a large (n 1⁄4 93,060) sample from the ETHOS (Exercise Testing and Health Outcomes Study) cohort. In this cohort, CRF was estimated as the peak metabolic equivalents (METs) derived from the peak speed and grade obtained on a treadmill exercise test. The findings from the single measure of CRF showed, compared with the low-CRF group (w5 METs), reductions in mortality rate across each higher-CRF group in both those …

Commentary On “Infants With Torticollis Who Changed Head Presentation During A Physical Therapy Episode”, Kathryn Knudsen, Ryan Jacobson, Kirsten Pepperling

Faculty Publications - College of Physical Therapy

This article highlights the importance of differential diagnosis in infants with congenital muscular torticollis (CMT), particularly those with atypical presentation or change of side for range-of-motion (ROM) restriction. Per the clinical practice guideline (CPG), patients who change sidedness with CMT should be reevaluated by the physical therapist and referred back to the primary care provider for consideration of other diagnoses.1 This recommendation is important to parents who are seeking accurate information on cause and severity and who want to know that the home exercises being prescribed for their infant are effective

Improving Interpretation Of The Patient-Reported Outcomes Measurement Information System (Promis) Physical Function Scale For Specific Tasks In Community-Dwelling Older Adults, Jeff Houck, Ryan Jacobson, Michael Bass, Chris Dasilva, Judith F. Baumhauer

Faculty Publications - College of Physical Therapy

Background and purpose: New generic patient-reported outcomes like the Patient-Reported Outcomes Measurement Information System (PROMIS) are available to physical therapists to assess physical function. However, the interpretation of the PROMIS Physical Function (PF) T-score is abstract because it references the United States average and not specific tasks. The purposes of this study were to (1) determine convergent validity of the PROMIS PF scale with physical performance tests; (2) compare predicted performance test values to normative data; and (3) identify sets of PROMIS PF items similar to performance tests that also scale in increasing difficulty and align with normative data.

Telehealth Assessment Of Frailty In Community Dwelling Older Adults Using The Modified Physical Performance Test (Poster), Sara Duran, Jessica Yeadon, Forest Bingham, Kordell Mcpherson, Elyse Grant, Jaime Ball, Lyndsay Stutzenberger

Faculty Publications - College of Physical Therapy

Frailty in Older Adults

● Frailty is a health condition that effects increasing numbers of the population past the age of 65

● The modified Physical Performance Test (mPPT) is a test that assesses multiple dimensions of physical function with different levels of difficulty. It has been shown to assess frailty in an older adult population.

● Due to health care barriers, it may be advantageous to assess individuals via telehealth.

● It is critical to determine the concurrent validity of telehealth delivery of mPPT with that of a clinical setting to determine if it can increase access to care

Size-Weight Illusion With A Squatting Task (Poster), Amanda Laron, Maryssa Becker, Mason Flores, Mikaela Raudsepp, Nicole Seidl, Robin Dorociak, Andrew Meszaros

Faculty Publications - College of Physical Therapy

Hypothesis:

The SWI will be observed during a squat movement, resulting in initially a larger GRF through the lower extremity on the side of the larger cube and more vertical displacement of the side of the bar with the large cube.

The bilateral GRF and bar displacement will become symmetrical after 10 repetitions.

Participants will initially predict the larger cube is heavier and after completing the squatting task will perceive the smaller cube as heavier.
