The temporal and distance parameters of gait
were measured by the Stride Analyzer (B/L Engineering,
USA). The system consists of a pair of
innersoles with compression-closing footswitches,
which are responsive to weight-bearing, positioned
at the great toe, first metatarsal, fifth metatarsal
and the heel. The innersoles come in a variety of
sizes, and the forefoot and heel portions can be
overlapped to accommodate differing shoe sizes.
During a measured walk the footswitch data are
stored in a backpack, which is worn at the waist.
Following data acquisition, data were transferred
from the recorder unit to a personal computer for
display, storage, and analysis
