The Neuromotor Exercise Progression: A Quantitative Framework for the Classification and Progression of Neuromotor Exercises

Neuromotor exercise is recognized as a distinct domain of physical fitness, yet operational criteria for classifying the neuromotor demands of individual exercises and systematically structuring their progression remain limited. The aim of this paper is to introduce the Neuromotor Exercise Progression (NEP), a quantitative conceptual framework for the classification and progression of neuromotor exercises in musculoskeletal rehabilitation, fitness, and sport settings. Building on the conceptual principles underlying Gentile’s taxonomy and guided by the American College of Sports Medicine conceptualization of neuromotor exercise, the NEP characterizes each exercise according to four variables: level of balance challenge, level of destabilization, degree of coordination, and level of locomotion. Balance challenge reflects the demands imposed by posture, stance, and base of support, whereas destabilization is intended to reflect proprioceptive demands associated with unstable support surfaces and other perturbations to postural and joint stability. Each variable is operationalized at three levels of increasing neuromotor demand. Exercises are classified according to the number of neuromotor components simultaneously challenged and an overall score derived from the four variables. Progression is primarily achieved by integrating a greater number of neuromotor components and secondarily by increasing the overall score within each level. The NEP is intended to provide a systematic basis for identifying the neuromotor profile of an exercise and for selecting and progressing exercises according to individual needs and functional goals. As a conceptual proposal, the framework requires further validation.
