Resumen:
Abstract: Gyroscopes have been proposed as sensors for ambulatory gait analysis and
functional electrical stimulation systems. Accurate determination of the Initial Contact of
the foot with the floor (IC) and the final contact or Foot Off (FO) on different terrains is
important. This paper describes the evaluation of a gyroscope placed on the shank for
determination of IC and FO in subjects walking outdoors on level ground, and up and down
an incline. Performance was compared with a reference pressure measurement system. The
mean difference between the gyroscope and the reference was less than 25 ms for IC and
less than 75 ms for FO for all terrains. Detection success was over 98%. These results
provide preliminary evidence supporting the use of the gyroscope for gait event detection
on inclines as well as level walking.
