Clinical Practice Guidelines: The Road Map To Better Care, Mary I. Fisher

Physical Therapy Faculty Publications

Systematic reviews and meta-analyses are important tools in translating research evidence into clinical practice as they critically evaluate and summarize the body of evidence on clinical topics. Clinicians can use these studies to quickly survey the current literature base to increase understanding of a clinical diagnosis they make, with the intent of using this information to improve their clinical practice. A well-written systematic review or meta-analysis, with critical evaluation of study quality, is then that Cliffs Note version of what to know and what to do. Therefore, with the proliferation of systematic reviews and meta-analyses, we should see a corresponding …

Finite element models can predict subject-specific chondrolabral stresses and help to elucidate the effect of under-coverage and incongruency of the hip joint in patients with dysplasia. However, complex stress patterns are difficult to generalize and evaluate statistically. With an established correspondence across shapes from statistical shape modeling (SSM), statistical parametric mapping (SPM) allows for evaluation of local variability while preserving model subject-specificity. Herein, we evaluated the combined application of SSM and SPM to compare cartilage contact stress between control subjects and patients with dysplasia.

Previously published hip joint contact stresses were mapped onto chondrolabral surface meshes and incorporated into an …

Developmental dysplasia of the hip (DDH) is described as under-coverage of the femoral head by the acetabulum, resulting in mechanical instability. Though DDH is often diagnosed using plain film radiographs, these images cannot adequately capture 3D joint coverage. Herein, we applied a 3D statistical shape model (SSM) to the femur and hemi-pelvis of patients with DDH to objectively measure shape variation and evaluated whether SSM outputs could predict measurements of joint coverage.

The femur and hemi-pelvis were semi-automatically segmented from CT images (83 hips from 47 females with DDH). Surfaces of each hip were reconstructed from segmentations, aligned, and input …

Rate Of Intraoperative Proximal Femoral Fractures With Automated Broaching, Tyler Radack, Hope Skibicki, Julian Zangrilli, Ruchir Nanavati, Cole Kleinman, Michael Harrer

Rowan-Virtua Research Day

Intraoperative proximal femur fractures (PFF) occur in 3.7% of total hip arthroplasties (THA) using the standard mallet broaching technique and increase a patient’s risk of revision surgery from 3.4% to 10%. The Depuy KINCISE automatic broaching system is designed to attenuate the risk of these fractures by applying consistent co-linear force to the broach. The aim of this study is to determine if the KINCISE system decreases the rate of intraoperative PFF fracture during THA compared to the standard mallet technique.

Use Of Osteopathic Manipulative Treatment In Alleviating Hypertonic Chest Wall Pain, David Ho, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We present the case of a 20-year-old male patient with no cardiac history coming in for left sided chest pain described as “burning” sensation. On physical exam, it was noted that patient had hypertonic chest wall muscles that were tight and spastic when palpated on the left chest wall. We used Osteopathic Manipulative Treatment (OMT) to help patient relieve hypertonic muscle. We chose to use muscle energy technique (MET) since this relies on reciprocal inhibition with the end result being relaxation of the target muscle.

The patient had resolution of chest pain after applying the technique. Although we did not …

Does Prehabilitation Prior To Ulnar Collateral Ligament Surgery Affect Return To Sport Rate Or Time In Baseball Players With Partial Ucl Tears?, Joshua Spada, Kourtney Snigar, Ryan W. Paul, Usman Zareef, Anya Hall, Brandon J. Erickson, Michael G. Ciccotti, Stephen J. Thomas

Rowan-Virtua Research Day

Those who suffer a partial thickness ulnar collateral ligament (UCL) tear often undergo a period of nonoperative management including physical therapy rehabilitation. This treatment is aimed at optimizing range of motion (ROM) and strengthening the supporting structures around the elbow to help offload the UCL.

Unfortunately, some of these patients fail nonoperative management and require surgical intervention. This creates a unique set of patients who essentially underwent “prehabilitation” prior to their UCL surgery. Prehabilitation is considered a period of structured physical therapy rehabilitation aimed at strengthening structures surrounding an injured tendon or ligament, to allow for dissipation of stress away …


A Review Of The Effectiveness Of Osteopathic Manipulative Medicine At Alleviating Pregnancy-Related Pain, Alexandria Lomanno, Olivia Choi, Danielle Cooley May 2022

A Review Of The Effectiveness Of Osteopathic Manipulative Medicine At Alleviating Pregnancy-Related Pain, Alexandria Lomanno, Olivia Choi, Danielle Cooley

Rowan-Virtua Research Day

Globally, more than a quarter of pregnant patients experience low back pain (LBP) during pregnancy with additional complaints of pelvic girdle pain (PGP) and other somatic dysfunctions. Though the standard of care for LBP in pregnancy is often analgesics, concerns about potential side effects that may cause lasting harm to the fetus may preclude pregnant patients from taking pain medications. Osteopathic Manipulative Medicine (OMM) is a nonpharmacologic treatment option that is routinely used for LBP in non-pregnant patients. Given the low risk of adverse effects, OMM may prove to be beneficial for pregnant patients suffering from LBP or PGP.

Use Of Pocus And Omt For Anterior Shoulder Reduction, David Ho, James Espinosa, Alan Lucerna, Neeharika Bhatnagar

Rowan-Virtua Research Day

Shoulder dislocations are very a common presentation in the emergency department. This represents about 50% of all joint dislocations presenting to the ER. Over 95% of the dislocations are anterior. Approximately 70% of shoulder dislocations occur in men and in both genders, the prevalence of shoulder dislocations occurs in a bimodal distribution in age in those younger than 20 and over 60 years old. Shoulder dislocation can occur anteriorly, posteriorly, and inferiorly. In an anterior dislocation, excessive force from external rotation and abduction causes a tear in the anterior ligamentous capsule3, causing the humeral head to dislocate from the glenoid …

Comparing The Relapse Rate Between Medication Assisted-Only Treatment And Medication-Assisted Treatment With An Osteopathic Manipulative Treatment Regimen In Patients With Musculoskeletal Pain, Karen Huang, Danielle Cooley

Rowan-Virtua Research Day

Since the opioid crisis first began in 1991, opioid-related overdoses in the United States have continued to increase dramatically, killing nearly 47,000 people in 2018, and making it one of the most pressing issues in healthcare. The most reported reason for misuse of pain relievers was to relieve physical pain. The increase in opioid abuse has also led to an increase in patients seeking medication-assisted treatment (MAT).

Osteopathic manipulative treatment (OMT) has been shown to have efficacy in relieving both chronic and acute pain. No current studies have investigated the use of OMT as an adjunct treatment to MAT for …

Return To Sport Following Closed Reduction Of Acute Traumatic Posterior Sternoclavicular Joint Dislocations: A Systematic Review, Seungkyu Park, Joseph Galvin, Matthew Nowak, Jordan Damschen

Rowan-Virtua Research Day

Acute traumatic posterior sternoclavicular (SC) joint dislocation is a serious injury given its potential to cause cardiovascular and airway compromise that typically will require emergent closed reduction. Posterior SC joint dislocations are usually caused by a high energy mechanism. Typical treatment involves closed reduction followed by observation. There is limited data on the rate of return to sport following this injury pattern when treated in a closed fashion.


Lung Hernia: An Uncommon Cause Of Pleuritic Chest Pain, Brittany Fera May 2022

Lung Hernia: An Uncommon Cause Of Pleuritic Chest Pain, Brittany Fera

Rowan-Virtua Research Day

Lung hernia is a rare but important consideration in the differential diagnosis of chest pain in patients with recent thoracic trauma or a history of thoracic surgery. Patients who undergo an anterior approach to thoracotomy, as was the case with our patient, are at a higher risk for developing lung herniation as a result of inherent anatomical weakness and wider intercostal spaces anteriorly and inferiorly.

Severe Mixed Mitral Valve Disease Due To Massive Mitral Annular Calcification: A Case Report And Literature Review, Fateh Ali Tipoo Sultan, Sheema Saadia

Section of Cardiology

We present an unusual case of massive mitral annular calcification (MAC) leading to severe mixed mitral valve disease, viz severe mitral regurgitation and severe mitral stenosis. To our knowledge, severe mixed mitral valve disease secondary to MAC is extremely rare. The patient (a 65-year-old lady) presented with worsening shortness of breath and signs of congestive heart failure. Echocardiographic examination revealed massive mitral annular calcification. Despite the massive annular calcification, she had experienced neither embolism nor endocarditis in the past. Because of severe symptomatic mitral regurgitation and mitral stenosis, surgery was advised; however, the patient declined it.

Eagle Syndrome: Efficacies Of Medical And Surgical Treatments, Kirklin Mitchell

Capstone Showcase

Eagle Syndrome is a rare syndrome caused by elongation of the styloid process of the temporal bone or calcification of the stylohyoid ligament occurring in a very small percentage of the population that can cause a wide range of common symptoms, leading to it being often misdiagnosed. While there are no set standards for treating Eagle Syndrome, both pharmaceutical and surgical options exist. Pharmaceutical options are often ineffective in long term treatment so surgery is usually required for full symptom resolution. Transoral and Transcervical surgeries have similar efficacies but each come with important drawbacks when considering which type of surgery …

Investigating The Role Of The Skeletal Muscle In Amyotrophic Lateral Sclerosis Neuromuscular Junction Dysfunction, Agnes Badu-Mensah Dec 2021

Investigating The Role Of The Skeletal Muscle In Amyotrophic Lateral Sclerosis Neuromuscular Junction Dysfunction, Agnes Badu-Mensah

Electronic Theses and Dissertations, 2020-2023

Neuromuscular junction (NMJ) dysfunction has been identified as one of the earliest events in Amyotrophic Lateral Sclerosis (ALS) pathology. However, which tissue type induces NMJ disruption; be it the motoneurons (hMN), Schwann cells or skeletal muscle (hSKM) remains unresolved. While mechanisms by which ALS hMN contribute to NMJ dysfunction are well-described in literature, limited information exist on how the other tissue types in the tripartite synapse (hSKM and Schwann cells) induce and/or contribute to ALS NMJ disruption. A fair understanding of the role of each tissue type in NMJ dysfunction would help shape the trajectory of future ALS research and …
