The effect of short duration low back vibration on pain developed during prolonged standing.

The purpose of this study was to determine if vibration, a potential method of pain management, applied to the low back could alleviate pain developed during prolonged standing. Eighteen healthy individuals participated in a 2.5-h standing task during which vibration (3-min duration) was applied at the 2-h and 2.25-h marks. During the full 2.5 h, participants recorded their perceived pain scores every 15 min using a 10 cm visual analogue scale (VAS). Following each vibration bout, those who developed low back pain (LPB) reported statistically lower VAS scores compared to prior to the vibration; however, when the vibration ceased, LBP returned to pre-vibration levels. It appears that vibration may be an effective method of alleviating LBP caused by prolonged standing; however, the effects seem to be temporary. Further research is needed to investigate the optimal vibration frequency and time period to maximize pain management effectiveness.
