Manual Therapy

Outcome Measures


Dr O’Halloran has worked as a Physical Therapist in Australia, the UK and the US. He has been involved in working with professional sports teams in both Australia and the US as well as work with Australian National Lacrosse teams at World Championships. Prior to coming on board with the University of the Sciences, Dr O’Halloran worked as an adjunct at the University level and has been involved in program development and instruction of continuing professional education for Physical Therapists for many years in the US and abroad(Argentina). He has owned and operated several physical therapy practices in the Philadelphia area and has participated as an Orthopedic Manual Physical Therapy Fellowship mentor and had the pleasure of mentoring numerous awarded Fellows. His areas of research interest include the management of cervicogenic headache, subacromial pain syndrome, manual therapy and outcome measures.
