Discussion

Implication

Establishes normative bilateral pulse symmetry ranges in healthy adults; leaves open validation in vascular disease cohorts before clinical use.

Structured PICO

Population

40 normal subjects

Intervention

Multi-site photoplethysmography (PPG) pulse measurement at six peripheral sites (ears, thumbs, and big toes)

Comparator

Right versus left side comparisons

Outcome

Right-to-left side similarity in pulse waveform shape assessed by root mean square error (RMSE) and cross correlation analysissurrogate

Pulses from the right and left sides of normal subjects are highly correlated at the ears, thumbs, and toes, establishing a normative range for future comparison with vascular patient groups.
