Ten healthy subjects performed 20 trials involving the grasp of five objects of distinct size and shape. Joint angles were recorded, and digit trajectories were computed using forward kinematics. For a given subject, fingertip trajectories were consistent across trials. The different-sized objects largely produced movement along different portions of a stereotypical trajectory described by a logarithmic spiral. The spirals fit the actual finger positions with a mean error across all trials of 0.23 \u00b1 0.25 cm and accounted for over 98% of the variance in finger position. These patterns were consistent independent of initial finger posture. Subjects did not produce straight-line movements, either in Cartesian space or joint space. The direction of the thumb trajectories exhibited a greater dependence on object type than the finger trajectories, but still utilized a small percentage (&lt;5%) of the available workspace. These results suggest that restoration of a small but specific part of the workspace could have significant impact on function following hand impairment. <\/jats:p>","DOI":"10.1152\/jn.00546.2003","type":"journal-article","created":{"date-parts":[[2006,5,31]],"date-time":"2006-05-31T02:01:10Z","timestamp":1149040870000},"page":"3702-3710","source":"Crossref","is-referenced-by-count":151,"title":["Stereotypical Fingertip Trajectories During Grasp"],"prefix":"10.1152","volume":"90","author":[{"given":"D.
