I found this:
Exercise I:
While standing upright, the subject holds
his one arm vertically above his head and the head
is extended fully backwards so that the face is
looking up and nearly horizontal. From this standing
position he starts turning his body in the vertical
axis to right and completes five rotations at a near
uniform rate. At the end of five rotations he lowers
the arm and returns the head to the normal face
forward position.
He is trained to maintain a nearly constant rate
of rotation and to time his rotation so that he
completes five rotations in 30 sec (10 rpm). At the
end of five rotations, when he moves the head forward
he experiences marked vertigo for 15-25 sec. The
subject performs three such exercises with
clockwise rotation (CW) and three with counter
clockwise rotation (CCW) at intervals of 30 sec. The
duration of vertigo reduces with repetitions but does
not disappear altogether. With practice, the subjects
could easily increase the speed to five rotations in
20 sec (15 rpm). The direction of post-rotatory vertigo
is a follows: CW rotation produces CW rotatory
vertigo, and CCW rotation produces CCW rotatory
vertigo.
Exercise II:
The subject stands erect with the hands
close to the sides and locked at the back. He then
bends forward at the waist level so that the upper
trunk and head are in line and facing the ground. In
this position he starts rotation through vertical axis
at a uniform rate as in Exercise I. On completion of
five rotations, he stops and returns his upper body
to vertical position when he experiences well marked
vertigo for 15-25 sec. The direction of the post
rotatory vertigo is opposite to that in Exercise I, CW
rotation producing CCW vertigo and CCW rotation,
CW vertigo. The exercise is repeated thrice each in
CW and in CCW directions at intervals of 30 sec.
Exercise III:
Standing erect, the subject carries out
rotation of the head over the shoulders so that in a
CCW rotation, the head is fully flexed forward at
first, then on the right shoulder, then fully extended
backwards, then on to the left shoulder and again
fully forward. The rotations of the head are carried
out smoothly and at uniform rate. Thereafter, with
the head rotating, the subject starts walking forward
at a moderate pace to complete 20 steps. He then
stops, turns around and returns to the starting
position in the same manner, while the head is turning,
and repeats the procedure with CW rotation of the
head. During the exercise there may be a tendency
to lose balance and fall. He is, therefore, advised to
reduce the head rotation gradually till balance is
regained.
Exercise IV:
The subject is required to lie down on
a flat couch, bed or on a carpet. He then raises both
his legs together to assume a near vertical, head
down position, with the body resting only on the
shoulders and the head. The waist is supported by
the hands. He holds himself in this position for a
minute and then slowly lowers the legs to assume
the horizontal position again. The slow lowering is
important and any tendency of the head getting lifted
in the process is to be curbed by lowering the
buttocks gradually. The breathing is regulated so
that inspiration is maintained during the raising phase
and expiration during the lowering phase. After a
pause of one or two minutes the exercise is repeated
twice. This exercise is identical with the yogic posture
of Sarvangasana and is expected to familiarize the
subject with the sensation of shifting of abdominal
viscera upwards and rise of blood pressure in head
and neck as experienced with negative G.
The complete workout of the four exercises
needs 20 min and was required to be carried out at
least thrice daily. The subjects were advised to do
the exercises, preferably on empty stomach or at
least 2-3 h after food. They did the exercise under
supervision once every day and were required to
repeat them twice at their own convenience. It was
made clear that the success of the therapy and in
turn their success in flying training, depended fully
on their sincere repetitions of the exercises. All
efforts were made to motivate the subjects to carry
out the exercises regularly. Each subject was kept
off from flying for the initial 4 to 5 days of starting the
exercises. Flying was resumed thereafter with the
exercises continuing. Those subjects who could not
do the exercises properly were given exercises for
extended period up to 7-10 days, before resuming
flying. It was also emphasized that the trainee should
not as far as possible miss any flying related activity
or ground training while undergoing the therapy.
Besides, they were advised to carryout very thorough
preparation for their subsequent sorties. A periodic
follow up was maintained. The exercise schedules,
durations, repetitions and resumption of flying were
modified where necessary to suit the need of
individual cases. Most subjects resumed flying
training at the stage where they had left. Thereafter
they practiced exercises on an average twice daily
according to their convenience. Once they flew a
few sorties without any sickness they gained
confidence following which most of them gradually
discontinued the exercises as confirmed during
