Jaclyn "Megan" Sions is an Associate Professor in the Department of Physical Therapy at the University of Delaware, with secondary faculty appointments in the Biomechanics and Movement Science Interdisciplinary PhD Program. She directs the University's interdisciplinary Limb Loss Clinic and co-investigates the Delaware Spine Studies laboratory.

• Board-Certified Orthopaedic Physical Therapy Specialist
• Certified Exercise Expert for Aging Adults (APTA)
• MRI Level 1 User (University of Delaware)
• Advanced Clinical Instructor (APTA)

Her research focuses on evaluating and managing chronic health conditions like lower-limb amputation and low back pain. Using musculoskeletal ultrasound and MRI, she explores modifiable factors to improve rehabilitation outcomes. Key areas include:

• Geriatric low back pain management
• Mobility assessment in limb loss
• Biopsychosocial pain factors
• Prosthetic evaluation
• Trunk and hip biomechanics
• Pain sensitivity analysis

Recent publications highlight her work on pain presentation patterns, mobility metrics, and muscle characteristics in amputees and older adults with chronic pain. She collaborates on projects like the MASH Trial for hip/back pain subgroups and studies autonomic imbalance post-amputation.

Dr. Sions contributes to national committees including the Pain Practice Analysis for Physical Therapy Specialty Certification and the American Academy of Orthotists & Prosthetists' Outcomes Research Committee. She serves on the University's MRI Steering Committee and Faculty Rights & Responsibilities.

Teaching includes spine management, geriatrics, and musculoskeletal ultrasound imaging in the Doctor of Physical Therapy program. She mentors PhD dissertation committees, orthopedic/sports/geriatric physical therapy residents, and clinical researchers.
