Relationships Between Quadriceps Neuromuscular Function And Time From Surgery Following Acl Reconstruction Are Sex-Specific, Tatiana Restrepo

Honors Undergraduate Theses

Anterior cruciate ligament reconstruction (ACLR) is associated with persistent quadriceps dysfunction, including muscular weakness and altered spinal and cortical excitability. While recovery has been widely studied, most investigations focus on isolated domains and fixed postoperative time points. Emerging evidence suggests females often experience slower or less complete quadriceps recovery compared to males, yet the time-dependent nature of these sex-specific outcomes remains unclear. The purpose of this study is to examine whether relationships between time since ACLR and quadriceps neuromuscular outcomes differ by sex across muscular, spinal, and cortical domains. Adults aged 18–35 with a history of primary, unilateral ACLR were …

Comparison Of Gluteal Muscle Central Activation In Individuals With And Without Patellofemoral Pain, Michael Carpio, John S. Donohue, Jacob P. Kissman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Individuals with patellofemoral pain (PFP) often present with knee valgus during weight-bearing activities. Weakness in the gluteal muscles is thought to contribute to this condition, but recent studies suggest that hip weakness might be a secondary problem in this population. Central nervous system adaptations have been noted in persons with PFP, which can lead to altered muscle function, faulty movement patterns, and poor function. Experimentally, central activation can be quantified by a central activation ratio (CAR) via superimposed burst (SIB) during a maximum voluntary isometric contraction (MVIC) where the ratio of volitionally activated motor units to total motor units …

Evaluating The Effectiveness Of Cryoneurolysis As A Preoperative Intervention In Total Knee Arthroplasty: A Literature Review, Paul Bonilla, Anesu K. Murambadoro, Juan Pablo Flanagan, Victoria Elizondo, Aamir Ahmad

Research Symposium

Background: Total knee arthroplasty (TKA) is a highly effective treatment for knee osteoarthritis, but significant postoperative pain often necessitates opioid use. Over 70% of patients use opioid drugs 3 weeks after TKA and up to 15% of TKA patients develop opioid dependence, increasing the risk of adverse effects, infections, and contributes to costly revision surgeries.
