Figure 1. Rectified EMG and auto-spectra from two subjects.

Figure 1

A, sections of rectified surface EMGs recorded from abductor pollices longus (APL) (top panel) and abductor pollices brevis (APB) (bottom panel) from the right hand of a healthy 4-year-old male subject during isometric extension/abduction of the thumb. B and C, autospectra (1–90 Hz) constructed from 2 min of continuous APL EMG data (B) and APB EMG data (C), same data as A. D, sections of rectified surface EMG recorded from APL (top panel) and abductor pollices brevis (APB) bottom panel from the right hand of a healthy 35-year-old male subject during isometric extension/abduction of the thumb. E and F, autospectra (1–90 Hz) constructed from 2 min of continuous APL EMG data (E) and APB EMG data (F), same data as D.
