Surface EMG was obtained from lower limb, trunk and shoulder musculature in addition to arm acceleration. Data tapes were digitized upon their return to Earth. Preliminary results indicate that the addition of foot pressure results in an increase in lower limb muscle activation during the rapid arm movements. Preparation for Reaching During Locomotion - This project investigates how humans modify their gait characteristics during walking in prepration for reach for and grasping a variety of objects. Force plates, video-based motion analysis and segmental accelerometers are used to collect data as subjects traverse a walkway and grasp objects from a table.
Analyses focus on the preparatory components of both lower and upper limb motion.
An additional component of this project is the exploration of the role of psychological traits as they relate to the strategies used in preparation for reaching.
