067- Dr. Caroline Fagundes Discusses Vertebral Artery Strain, Posture and Falls

Dr. Caroline Fagundes and I discuss vertebral artery strain, posture and falls in this episode of the chiropractic science podcast. Dr. Fagundes always knew that her professional field would be in healthcare, and when she read about chiropractic, there were no doubts about which profession to choose. She graduated from chiropractic school in 2008 but continued to seek answers, which led her to a graduate degree in kinesiology at the Federal University of Rio Grande do Sul (Brazil).  This is where she also had her first contact with the research of Professor Walter Herzog.

In 2017, she was awarded a scholarship for the Master’s Degree in Cultural Diversity and Social Inclusion, in the area of Health and Social Inclusion – Aging. Her research was about the relationship between static posture and falls in elderly. In her PhD, also carried out with a scholarship, she continued to study this relationship and in 2021 she was awarded a scholarship to study abroad. Dr. Fagundes embarked on a trip to Calgary, Canada in September to study the strain caused in the vertebral artery during cervical movements and cSMT with Professor Herzog. She returned to Brazil in February 2022, and then finished her PhD and currently works as a chiropractor and acupuncturist in her own office in the South of Brazil.

054- Drs. Chris Malaya and Josh Haworth Discuss Motor Control, Posture and Chiropractic

Drs. Christopher Malaya and Joshua Haworth

Drs. Chris Malaya and Josh Haworth discuss motor control, posture and chiropractic research in this episode. Dr. Chris Malaya is a research associate at Parker University in Dallas, Texas. He graduated from Parker in 2018 with a Doctorate in Chiropractic and is currently pursuing a PhD in Motor Control from the University of Houston. His current research interests are in sensorimotor integration, postural control and adaptation, as well as the neural mechanisms of manual manipulation. His overall goal is to help expand the foundational mechanisms and practical applications of manual joint manipulation as it relates to movement and neural rehabilitation.

Dr. Josh Haworth’s research focuses on the mechanisms responsible for the integration of sensorimotor information in the production of human behavior. He uses eye-tracking combined with motion capture and posturographic measures to identify motor strategies used during daily tasks like upright standing, walking, and interpersonal communication. Extensions of this work include the identification of early indicators of clinical disorders and the production of novel therapeutic modalities. He has many active collaborations with colleagues in fields including chiropractic science and pediatric rehabilitation technology. He is focused to better understand the development of motor and social-cognitive skills in children with, and without, autism.

028- Is Sitting Killing You? Dr. Diana De Carvalho Discusses Seated Spine Posture

Is sitting killing you? What kind of posture should you have seated or standing? How much time should you sit versus stand at work? How much spine flexion is too much? Can chiropractic manipulation help with seated postures? These are some of the many questions that are addressed in this interview. Dr. Diana De Carvalho is an Assistant Professor at Memorial University of Newfoundland in the Discipline of Medicine, Faculty of Medicine. She holds the Canadian Chiropractic Research Foundation Professorship in Spine Biomechanics and is cross-appointed to the School of Human Kinetics and Recreation.

After completing a BSc in Human Kinetics at the University of Guelph (2002), she attended the Canadian Memorial Chiropractic College graduating with the class of 2006. Concurrent to part-time clinical practice, Dr. De Carvalho completed a Certificate in University Teaching along with her MSc (2008) and PhD (2015) in Kinesiology at the University of Waterloo. She has extensive experience with industry-partnered research involving both automotive and ergonomic office seating.

Directly related to decreased productivity, decreased quality of life and high health care costs, low back pain might be the first of many negative health outcomes experienced by sedentary workers. Dr. De Carvalho’s research program focuses on spine mechanics, especially in response to sustained flexion, in order to better define and direct early diagnosis, prevention and intervention strategies for low back pain.
In addition to numerous peer-reviewed conference presentations both at the national and international level, Dr. De Carvalho has published articles in such journals as JMPT, Applied Ergonomics and Human Factors and she is an editorial board member of the Journal of the Canadian Chiropractic Association.
