Background and Aim: Whole body vibration (WBV) is a new therapeutic modality which improves muscle function, proprioception and postural control by creating an oscillatory mechanical stimulation. The aim of this research was to investigate the immediate effect of WBV on postural control in young adults.

Materials and Methods: In this quasi-experimental study, 22 healthy subjects were participated as a single group. Non-probability simple sampling method was used. Subjects were treated with 4 minutes WBV bout. The subjects repeated four times a 60-s light exercise program according to instructions which was shown by the therapist. During the vibration intervention, the vibration frequency increased in 1 minute intervals from 15 Hz for the first minute to 30 Hz for the last minute. Postural control indexes were recorded using the Biodex Balance system in situations of two leg standing with open and close eyes that included overall stability index (OSI), anterior-posterior stability index (APSI), medial-lateral stability index (MLSI) . In order to analyze the data, paired t-test was used.

Results: The results indicated that in the case of standing on two legs with eyes open, OSI and MLSI were statistically significant (P = 0.02; P = 0.01, respectively) and with eyes closed, OSI, APSI and MLSI were statistically significant (P = 0.000; P = 0.001; P = 0. 001, respectively).

Conclusion: Four minutes WBV bout can induce improvement of postural control and balance in young adults.
