In order to explore a possible relationship between postural behavior on the treadmill and during normal upright stance, we briefly examined the participants on a stabilimeter platform.
All the RMS values recorded by the stabilimeter for our group fell well within the norms for normal postural balance behavior (Roos, 1991) and, indeed, differed little from one another.
During the first 48 hours of life the subject was placed in a special crib in the laboratory; electrodes were placed on the chest and leg to monitor heart rate, a pneumobelt encircled the abdomen to record respiration and activity level was monitored by a strain-gauge stabilimeter
. A grass polygraph recorded these functions on separate channels.
