Immediate effect of different modes of one-session vibration on propriception of knee joint

Qiu Yepeng, Zhang Tingran

Purpose: To explore the influence of two vibration training methods (static and dynamic vibrations) on proprioception of knee-joint.

Method: Recruiting 12 healthy male students (similar in height, weight, and age) in Southwest University and adopting angular instrument and JVC camcorder to monitor knee-joint proprioception of subjects who have received different vibration trainings, so as to reveal vibration training’s change to knee-joints’ active and passive proprioception in open and closed-kinetic-chain modes.

Results: According to active and passive angle tests on open-kinematic-chain knee-joint and passive angle test on closed-kinetic-chain knee-joint of legs, error in non-intervention mode is remarkably larger than that in dynamic and static vibration intervention modes when the subjects are tested in these three modes. The comparison among the three intervention modes show that the dynamic vibration training is superior to vibration training whereas the static training is superior to no training according to the error in active and passive angle tests on open-kinematic-chain knee-joint and passive angle test on closed-kinetic-chain of dominant leg.

Conclusion: Vibration training exerts remarkable effect on improvement of proprioception of knee-joint and it is more suitable to adopt dynamic vibration training.
