Developmental processes cross the lifespan and lead to acquisition of new behaviors, adaptation to changing circumstances, and recovery following injury or illness. Using examples from my own work and others in upper extremity stroke rehabilitation, I argue that randomized clinical trials have provided limited information for clinicians. We need a broader view, which recognizes that humans have distinct developmental paths and cannot be treated like genetically similar animal models in the traditional experimental method. Complexity, individuality and variability of past experience, current residual capacities and environmental conditions lead to learning, including recovery learning by adults after stroke. This perspective is incorporated in innovative rehabilitation interventions and research approaches. Informative and satisfying to non-reductionists/science skeptics, these examples also offer practical insights to Feldenkrais® teachers and other practitioners.

Jill Whitall, PhD, is a professor in the Department of Physical Therapy and Rehabilitation Science in the School of Medicine, University of Maryland, Baltimore. Originally trained in developmental control and coordination, Dr. Whitall has spent the last 15 years primarily investigating a specific bilateral arm training protocol for stroke and simultaneously determining neural mechanisms underlying recovery.
