Conservative treatment for PCOS includes dietary modifications and physical activity. The purpose of this scoping review was to evaluate the efficacy of a ketogenic diet in improving biochemical measures and reducing the severity of PCOS symptoms. Methods: CINAHL, PubMed, and Google Scholar databases were searched to find research published in peer-reviewed journals between 2019 and 2025. An article was included in this scoping review if the study assessed …

Running Biomechanical And Isokinetic Strength Differences In Masters Runners With And Without Achilles Tendinopathy, Matthew Klein, Christopher Patterson, Annette Karim, Tyler Cuddeford

Faculty Publications - College of Physical Therapy

Masters runners are an increasing proportion of the running com-munity. The most significant musculoskeletal changes in runners occur after the age of 50 in addition to changes in injury rates and types, the most common being Achilles tendinopathy (AT). Previous evidence has suggested similarities between risk factors for AT and age-related changes that are focused at the hip and the ankle during the propulsive stage of running. The purpose of this study was to investigate biomechanical and peak torque association to AT in masters runners. Thirty-two masters runners over age 50 with AT(60.31 ± 8.37, n = 16) and without …

Commentary On “Predictors Of Length Of Physical Therapy Care For Infants With Congenital Torticollis”, Ryan Jacobson, Kathryn Knudsen, Katherine Binkerd

Faculty Publications - College of Physical Therapy

Most infants in this study were ≤3 months of age and 94% had severity grades I or II. Clinicians might prioritize accurately measuring active neck rotation using an arthrodial goniometer in younger, less severe infants, since active neck rotation deficit had the highest single-factor correlation with episode length and reflects degree of asymmetry in neck and torso strength. While the Alberta Infant Motor Scale and previous tummy/container time factors were not associated, we appreciate the efforts of the authors to address this gap in the literature.

Hopping Kinetic Differences In Masters Runners With And Without Achilles Tendinopathy, Matthew Klein, Chris Patterson, Annette Karim, Tyler Cuddeford

Faculty Publications - College of Physical Therapy

Achilles tendinopathy (AT) is the most common running-related pathology among masters runners. Previous evidence suggests there are no differences in submaximal running biomechanics between masters runners with and without AT. Evidence suggests lower extremity power deficits are common among ageing individuals and those with AT. The single-leg horizontal hop (SLHH) test isa valid and reliable lower extremity power test. The purpose of this study was to investigate differences in SLHH biomechanics between masters runners with and without AT. 32 masters runners age 50 and older with AT (60.31 ± 8.37, n = 16) and without (59.94 ±4.95 n = 16) …

The Importance Of Trunk Motion In Wearable Based Infant Spontaneous Movement Analysis, Pablo Burgos

Faculty Publications - College of Physical Therapy

The characteristics of spontaneous movements in infants are essential for the early detection of neurological pathologies, with the Prechtl method being a widely recognized approach. While the Prechtl method is effective in predicting motor risks, its reliance on the evaluator’s expertise limits its scalability, particularly in low-income areas. In such contexts, the use of inertial sensors combined with automated analysis presents a promising accessible alternative; however, more research is necessary to get results comparable to those of the Precht method. This research aims to determine the more important metrics of trunk and limbs to assess spontaneous movement in healthy infants …

Cognition Is Associated With Daily-Life Mobility In People With Parkinson’S Disease, Pablo Burgos

Faculty Publications - College of Physical Therapy

Introduction: Cognitive impairment is common in people with Parkinson’s disease (PD). Mobility is also impaired in people with PD and functional mobility often requires cognitive dual-tasking to navigate complex environments in daily life. We hypothesized that visuospatial and executive cognitive dysfunction in people with PD will be associated with digital measures of mobility in daily life. Since freezing of gait (FoG) is associated with both cognitive dysfunction and mobility impairments, we also examined the influence of FoG on the cognitionmobility relationship. Here, we investigated, for the first time, the association between cognition and dailylife mobility in PD and the influence …

Responsiveness Of Promis Measures For Hip, Knee, And Shoulder Arthroplasty, Ryan Jacobson

Faculty Publications - College of Physical Therapy

Objectives: In hip, knee, and shoulder arthroplasty, there is evidence that using a broader set of Patient-Reported Outcomes Measurement Information System (PROMIS) measures beyond Physical Function and Pain Interference might improve assessment of patient outcomes. However, the utility and responsiveness of PROMIS domains measuring anxiety, fatigue, sleep, and social participation have been minimally investigated in arthroplasty. This retrospective study aimed to determine the 1) responsiveness of seven PROMIS domains and 2) association between change scores for all seven domains and MCID improvement in Physical Function and/or Pain Interference.

Methods: PROMIS domains of Physical Function, Pain Interference, Depression, Anxiety, Fatigue, Sleep …

The Use Of Virtual Reality To Improve Gait And Balance In Patients With Parkinson’S Disease: A Scoping Review, Jason Brumitt

Faculty Publications - College of Physical Therapy

(1) Background: Parkinson’s disease (PD) is a progressive neurodegenerative disorder that impairs balance and postural control, gait, overall motor function, and mood, and involves the gradual degradation of several physiologic systems. With limited treatments available, physical therapy (PT)-based exercise is the nonpharmacologic measure of choice. There is a growing interest in using virtual reality (VR) gaming when rehabilitating patients with various acute brain injuries and neurological disorders. The purpose of this scoping review was to examine randomized controlled trials comparing VR-based rehabilitation programs versus traditional PT at improving gait and balance. (2) Methods: PubMed, CINAHL, and the Cochrane Central Register …

Personalized Versus Fixed Tactile Cueing In Parkinson’S Disease: Protocol For A Randomized Controlled Trial On Gait Automaticity, Pablo Burgos

Faculty Publications - College of Physical Therapy

Background

Gait automaticity, the ability of the brain to control locomotion with minimal use of executive-attentional resources, is altered in people with Parkinson’s disease (PD). Recently, we showed that step-synchronized tactile cueing improved gait regularity and freezing of gait in PD; however, it is not known if this cueing mode also improves gait automaticity. Thus, this study investigates the effects of step-synchronized tactile cueing (versus fixed cueing) on gait automaticity in the laboratory and during daily life.

Methods

This is a pilot, randomized, double-blinded study where sixty participants with PD will be randomized into one of two, cueing interventions: 1) …

Objectives: Identify the scope of the problem of SUI in women participating in strength sports, movement patterns that elicit SUI, and the impact on quality of life in female athletes with SUI. Study Design: Survey mixed methods with qualitative focus groups. Methods: The International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) and a sport-specific and obstetric/gynecological history questionnaire were sent to women who are United States citizens, age 18-65, and members …

Weight Stigma In Physical And Occupational Therapy: A Scoping Review, Jason Brumitt

Faculty Publications - College of Physical Therapy

Background: Weight stigma describes the negative attitudes held toward people with obesity. Weight bias stereotypes have been previously reported in physicians, physician assistants, nurses, registered dieticians, psychologists, and students enrolled in healthcare professional education programs. Physical and occupational therapists (PTs and OTs) are healthcare providers who evaluate and treat individuals across their lifespan. A PT or an OT who harbors weight bias may create an environment where the patient may fail to optimize their rehabilitation recovery. The first purpose of this scoping review was to identify the prevalence of weight bias in PT and OT clinicians and students. The second …

Changes In Quadriceps Strength In Recreationally Active Individuals Using Single-Limb Or Double-Limb Blood Flow Restriction, Brogan Boen, Logan Cockrell, Olivia Aho, Taylor Bryant, Bethany Nguyen, Jason Brumitt

Student-Faculty Research - College of Physical Therapy

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.

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)?

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 …

Embedding Physical Therapy In The Pediatric Primary Care Setting: Qualitative Analysis Of Pediatricians’ Insights On Potential Collaborative Roles And Benefits, Ryan P. Jacobson, Rebecca R. Dobler

Faculty Publications - College of Physical Therapy

The growing need for collaborative healthcare teams to meet complex health challenges has led to physical therapists (PTs) being embedded in adult primary care settings for many years now. However, this model of care has not been found in pediatrics. This qualitative study sought to gain insights from pediatricians on the potential of embedding pediatric PTs in primary care. Participants were nine pediatricians practicing in both urban and rural, hospital-based and private settings. Semi-structured interviews were recorded, transcribed, and analyzed via thematic analysis per published methods, assuring trustworthiness. Three overarching themes emerged: pediatricians’ priorities aligned with the Quadruple Aim of …

Running Shoes For Posterior Tibial Tendon Problems, Matthew Klein

Faculty Publications - College of Physical Therapy

Our perspective on stability and guidance are one of the many things that make Doctors of Running unique. I, Matt Klein, generally need at least mild stability in my footwear. Like many of our readers, I have continued to navigate and understand what a stability shoe is, what options there are out there, what actually provides stability/guidance and who stability actually works best for. Recent research has suggested that stability shoes tend to benefit those with a history of pronation-related injuries or who are unable to control the natural pronation motion during gait (Malisoux et al., 2016; Williems et al., …

Effect Of Perturbation-Based Balance Training On Fall Risk And Fear Of Falls In Community-Dwelling Older Adults – A Pilot Study, Lindsey Kelly, Casey Kostecki, Garrett Markham, Conner Morris, Trevor Strem, Lyndsay Stutzenberger, Gabe Haberly

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 …

Student-Faculty Research - College of Physical Therapy

Patients are referred to PT everyday, but referrals can delay care. Early care is preferred, but getting to the right healthcare provider at the right time is ideal. Upstream PT improves patient care and clinician experience. Purpose: Implement PT within pediatric primary care.

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 …

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.

Comparing Self-Reported Sleep Quality And Sleep Disturbance With Physical Activity In Community Dwelling Older Adults, Sophie Larue, Morgan Hendley, Brandon Tandecki, Kirsten Cabrera, Faerynn Tilgner, Brad Higa, Christen Johnson, Cindy Zablotny, Theresa Raudsepp, Jeff Houck

Student-Faculty Research - College of Physical Therapy

Purpose:

To evaluate physical activity and sleep health in community dwelling older adults through use of activity monitors, physical capacity tests, self-reported sleep health, physical health measures, and participation in social roles. We wanted to know how these measures may or may not play a significant role in future physical therapy treatment. Our hypothesis was that self- reported sleep quality and sleep disturbance is correlated to physical activity in community dwelling older adults.

Running Shoes For People With Haglund's Deformity, Matthew Klein

Faculty Publications - College of Physical Therapy

Heel counters are one of the many footwear components that are commented on here at Doctors of Running. Heel counters are (usually) a rigid piece of material embedded in or molded around the upper of the rearfoot. The purpose is to provide structure to this part of the shoe and potentially stabilize the heel. There are now several variations, going from ones that wrap completely around the heel, to split heel counters (a piece left out at the rearmost portion) and even super thin heel counters just to keep the upper from collapsing. While many people do well with these …

Everything You Need To Know About Running Shoe Wear Patterns, Matthew Klein

Faculty Publications - College of Physical Therapy

Look online for information on running shoes and you’ll soon see articles about wear patterns on the bottom of your shoes. Usually, these articles promise “secret knowledge” of what each wear pattern means and what horrible injury you’re therefore due. Individual companies often claim that certain wear patterns mean you need specific shoes or orthotics, which, lucky for you, they happen to be selling.

Most of this information is flat-out wrong. There’s simply no compelling evidence linking wear patterns on your running shoes with an increased risk for a given injury. Nor is there a relationship between your wear …
