Objectives:
Functional asymmetry is a hallmark of aging-related motor decline, contributing to impaired gait, balance deficits, and increased fall risk. This study aimed to evaluate the effects of a single session of Neuro Postural Optimization (NPO), a non-invasive neuromodulation protocol based on Radio Electric Asymmetric Conveyer (REAC) technology, on central neurophysiological balance and functional symmetry in older adults.
Methods:
Eighteen participants (mean age: 72.4 ± 6.1 years) underwent a standardized REAC-NPO session. Assessments were performed immediately before and after treatment using the Timed Up and Go (TUG) test, the Gait Speed test, the Five Times Sit-to-Stand (FTSTS), and Handgrip dynamometry.
Results:
Statistically significant improvements were found in TUG (p=0.026), Gait Speed (p=0.041), and FTSTS (p=0.003). No significant change was observed in handgrip strength (p=0.530), supporting a central rather than peripheral mechanism of action. Functional dysmetria, a reproducible and quantifiable indicator of maladaptive central motor control, was completely corrected in all participants immediately after the REAC-NPO session.
Conclusions:
A single REAC-NPO session can restore functional symmetry and improve mobility-related outcomes in older adults. The immediate and complete correction of functional dysmetria supports the potential role of REAC-NPO in fall prevention strategies and functional recovery programs for aging populations.
