Abstract

Background: The purpose of this study was to investigate how the resistive exercises with vibration stimuli could affect the strength of knee muscles and balance in patients with a history of reconstructive surgery.
Methods: Thirty four subjects with anterior cruciate ligament reconstruction were randomly divided into 3 groups; Resistive exercises with vibration stimuli group (n=11), Resistive exercises (n=11) and control group (n=12). The paired t-test was used to show the variation before and after exercise in all three groups. One way ANOVA was used to separate the total variation between groups.
Results: The results showed that there was significant improve in the strength of knee muscles in all three groups and resistive exercise with vibration stimuli he group showed a better result in all area than the other two groups. Comparisons of sway distances with open and closed eyes showed a statistically significant decrease before and after treatment in all three groups, there was no statistically significant difference between groups. There was a significant difference only in the sway distance with the eyes closed.
Conclusions: Applying the resistive exercise with vibration stimuli as a therapeutic exercise program resulted in a positive effect to the functional activity not only in rapidly recovering the strength the weaken muscles and lost of balance ability, but also expecting an earlier return to daily life by advancing the date of the process for the functional activity.
