Annalisa Na


Assistant Research Professor

Physical Therapy and Rehabilitation Sciences Department

Annalisa Na, PhD, PT, DPT, is an assistant professor in the Department of Physical Therapy and Rehabilitation Sciences. She completed her postdoctoral training in the Department of Orthopaedic Surgery and Division of Rehabilitation Sciences at the University of Texas Medical Branch in Galveston on clinical outcomes and multimorbidity management in older adults. She completed her doctorate in Physical Therapy at Duke University and PhD in Biomechanics and Movement Sciences at the University of Delaware. Before pursuing research, she worked in outpatient orthopedics, completed an orthopedic physical therapy residency through Proaxis Therapy and Evidence in Motion, and achieved board certification as an orthopaedic clinical specialist.

Research Interests

Na’s research interest includes exploring the mechanistic relationships of multimorobidities commonly associated with knee pain, identifying biomechanical, clinical, and behavioral strategies that facilitate mobility and disrupt chronic diseases and examining strategies for the implementing effective interventions in clinic and community settings that facilitate long-term outcomes and promotes self-management of knee pain and multimorbidities among older adults.


Na’s research targets the interactions of multimorbidity diseases on functional outcomes in older adults. Her work attempts to understand strategies for reducing the risk of developing or exacerbating metabolic diseases (e.g., diabetes and obesity) among older adults with mobility-limiting knee pain. Her current study examines the influence of existing interventions for knee osteoarthritis, total knee arthroplasty, and Type 2 diabetes mellitus on physical function and glycemic control outcomes. This study is funded by the geriatric research grant from the Foundation for Physical Therapy Research. Na’s research has also been supported by the Academy of Orthopaedic Physical Therapy and the Academy of Geriatric Physical Therapy for examining the biomechanical factors associated with self-reported walking difficulty in knee osteoarthritis.
