[Effect of immersion hypokinesia on kinematic and electromyographic parameters of human locomotion].
Kinematics and electromyographics of the normal walking pattern were studied in 6 volunteer (22-25 y.o.) before and after immersion. It was shown that 6-d support deprivation results in reduction of angular velocities in the knee and ankle joints and minor change in the amplitude of angular motions of the joints. However, the kinematic stereotype of locomotor motions was not changed considerably following 6-days in immersion. Increase of the electromyographic cost of shin locomotion points to shifts in the central and peripheral systems of the motor apparatus.
