(1) To study the long-term adaptation of grip-force/load-force coordination to the microgravity environment.
a. Effects of weight versus mass
b. Optimization of movement kinematics and dynamics
c. Grip force during controlled collisions
(2) To study the interaction between cognitive and proprioceptive cues with respect to control of grip force and movement kinematics for “upward” versus “downward” movements.
There will be three preflight Baseline Data Collection (BDC) sessions beginning at L-180 (Launch-180) days and four full postflight BDC sessions beginning at R+4/5 (Return to Earth + 4/5) days and ending at later than R+30 days, with one abbreviated postflight BDC session on R+1. Four inflight sessions will take place. Each of the full sessions will be divided into 3 sub-sessions (Movement dynamics, Reference frames, and Collisions) with at least 30 minutes of other activities between sub-sessions to help maintain subject alertness. Movement of object and hand will be measured as will the load force that moves the object and the grip force that prevents the object from slipping from the hand.
Results for this investigation are unavailable. This is an international experiment. NASA does not currently have an agreement with international space partners to archive their data in the LSDA.
