Proprioception can be affected by many factors including exercise.
Most exercises involve certain degrees of repeated passive movements, and
different velocities of these movements might affect proprioception differently.
The purpose of this study was to evaluate the influences of different angular
velocities of repeated passive movement on knee proprioception via active
repositioning and kinesthesia measurement. METHODS: A quasi-experimental design
with repeated measure on movement velocity (0 degrees /s, 2 degrees /s, 90
degrees /s, and 150 degrees /s). Sixteen healthy young adults participated in the
study. All of them received 30 times repeated passive knee movement intervention
in four different knee angular velocities - 0 degrees /s, 2 degrees /s, 90
degrees /s, and 150 degrees /s - with counter-balanced sequence in four
successive days. Knee active repositioning and kinesthesia were measured with
error scores before and after the intervention. FINDINGS: The results revealed a
decrease in error scores in both active repositioning and kinesthesia measurement
with the velocities of 90 degrees /s and 150 degrees /s (p<0.05); however no
significant change was seen with the static condition (0 degrees /s ) or with the
velocity of 2 degrees /s. INTERPRETATION: We concluded that repeated passive
movement with rapid angular velocities was capable of improving knee
proprioception, specifically in active repositioning and kinesthesia
measurements. These results would provide information on the effects of different
movement velocities onto knee proprioception. Along with further investigations,
the findings could potentially enhance our knowledge on knee injury prevention,
treatment, and rehabilitation.
