Background
•Results from Dr. Bloomberg’s Functional Tasks Test (FTT) study has shown 
decrements in functional performance following long duration spaceflight. 
• R+1 is the earliest long duration (station) 
FTT data available. 
• Changes are greatest immediately following
gravitational transitions, where crewmember 
demand for emergency operations is most 
likely to occur.
What are the implications for interplanetary travel where crew landings will 
be unassisted?

Goals
1) Characterize the functional decrements immediately after landing.
2) Construct a recovery timeline of crewmember functional performance 
starting within hours of landing through the return to normative 
preflight levels. 
3) Compare efficacy of U.S. Gradient Compression Garment (GCG) as 
compared to the Russian Kentavr for control of orthostatic 
intolerance.
Aid in the development of programmatic risks for 
interplanetary travel.

1) Soyuz landing site (U.S. and Russian crews) 
2) Karaganda/Kustanai airport (U.S. and Russian crews)
3) Star City (Russian); 1st refueling site, e.g. Scotland (U.S.)
4) Star City (Russian); 2nd refueling site, e.g. Nova Scotia (U.S.)

1) Seat Egress & Tandem Walk Test
Unbuckle a harness, get up from a 
seat and complete an obstacle 
course. Repeated with chair supine.
10 tandem heel-to-toe steps will
then be taken with eyes closed.
On R+0, obstacle course will have 
simplified components of preflight 
course.

Note: on R+0 crewmembers will be wearing the Kentavr or GCG

2) Recovery from Fall / Stand Test
After 2 minute period of lying prone, 
stand up as quickly as possible and
remain standing for 3 minutes. 
This is performed the same on R+0.
3) Push Test
Maintain balance following a 
random-force perturbation applied to 
the sternum. 
This is performed the same on R+0.

4) Force Precision Test 
(Leg and Hand)
Apply a force to a hand or foot 
dynamometer such that each 
subsequent force increases from 
the last.
This is performed the same on R+0.
5) Hand / Eye Coordination Test
Accurately touch targets that are randomly presented on a 
computer touch screen using the finger, or a stylus. 
This is performed the same on R+0. At the Soyuz landing site, 
it would be possible to collect this data while crewmembers are 
in the recovery chair.

6) Intra-Ocular Pressure (IOP)
Look straight ahead and keep eyes open 
while IOP is obtained in the upright and 
supine positions.
This is performed the same on R+0. 
7) Intra-Cranial Pressure (ICP)
Stay relaxed and do not move as an audio 
tone is emitted through an earphone 
placed in the ear to obtain ICP in the 
upright and supine positions.
This is performed the same on R+0.

8) Postural Muscle Tone / Compliance 
Stay relaxed while a very small vibratory stimulus is applied 
to the lumbar muscles of the lower back and again to the 
postural muscles of the lower leg. 
This is performed the same on R+0. However, the calf 
muscle compliance cannot be obtained until the GCG 
or Kentavr is removed.
9) Dynamic Visual Acuity (DVA)
Use a joystick to accurately indicate the 
direction of the opening of a Landolt C 
in a time-optimal fashion. This is performed 
while stationary and again while sitting in a chair 
that oscillates at 2 Hz with a vertical displacement 
of ± 2 cm to match natural locomotion. 
This is performed the same on R+0.

11) Jump Down
Jump down from a platform with a 
height of 30 cm onto a force sensing 
plate. Four surface electrodes will be 
placed on the leg to assess changes 
in neuromuscular activation patterns.
This IS NOT performed on R+0. 
10) Motion Sickness (MS) Questionnaire
Reporting of MS symptoms will be performed using a computerized 
questionnaire and will be obtained periodically during testing. 
Overall MS rating will be reported on a scale of 1-20.

12) Rock Translation Test
Transfer three weights (6, 10, 20 lbs) with 
handles, one at a time, a distance of 8 feet 
and place in a receptacle and then transfer 
the weights back to the initial receptacle.
This IS NOT performed on R+0. 
13) Computerized Dynamic 
Posturography Test
Maintain balance on sway-referenced 
support surface with eyes closed. This test 
will be performed with and without head 
movements.
This IS NOT performed on R+0.

Study Relevance
1) Will allow us to develop a time constant of functional 
performance in the hours and days following long 
duration spaceflight that has not been captured 
previously.
2) Will allow us to determine which garment, the GCG or 
Kentavr, provides better protection against orthostatic 
intolerance.
3) Will provide a knowledge base from which 
programmatic risks for interplanetary travel can be 
developed.
