The ASO Newsletter - 50th edition

Enabling greater understanding of the Alexander Technique.

Introduction

This month’s blog post marks a milestone—our 50th episode! In this conversation, ASO team member Erica Donnison interviews Dr. Tim Cacciatore, co-author of the recently published paper Central Mechanisms of Muscle Tone Regulation: Implications for Pain and Performance.

Tim shares the background behind the research, clarifies key concepts, and explores how muscle tone regulation relates to balance, movement, and coordination. He discusses why understanding tone is crucial for Alexander Technique teachers, researchers, clinicians, and the public, shedding light on its role in pain management and performance. The conversation also delves into long-standing misconceptions about the reflex model, tracing its historical roots and explaining how modern neuroscience offers a clearer picture of the neurophysiological processes at play in AT lessons and daily life.

This is the first of a two-part discussion. Stay tuned for part II, where Erica and Tim will further explore how these insights connect with terminology and ideas commonly used in Alexander Technique teaching.

The paper is open-access (linked below) and designed for a wide audience—including teachers, researchers, and anyone curious about the science of movement. This conversation is packed with valuable insights—you might just want to watch it twice!

  If it’s not clear they use the term “equilibrium control” to mean balance.

About

Tim Cacciatore, PhD, is an expert in the neuroscience of postural tone and its relationship with movement coordination. He was motivated to study postural control because he thought the scientific literature lacked plausible explanations for how the Alexander Technique affected posture and helped his own back pain. His research has aimed to use somatic methods as a tool to reveal properties of the motor system. He has published numerous peer-reviewed articles with leading experts in motor control such as Drs Victor Gurfinkel, Fay Horak, and Brian Day at institutions that have included University College London, Oregon Health Sciences University, and the University of California, San Diego.
