Effects of smartphone task type and device handling configuration on postural stability and lower-limb load asymmetry during quiet standing: a randomized controlled study.

raw_data_posturography.xlsx contains anonymized participant-level data from a parallel-group randomized controlled trial (n=120; Control, Texting, Instagram, YouTube). The file includes pre and post 30-second standing measurements, demographic/anthropometric variables, and posturography outcomes (left/right load distribution, asymmetry index, and COP-based stabilographic parameters). No direct personal identifiers are included.
