  Objective: To explain how the analysis of vibration frequencies can be used to understand the contribution of vibration to lower back disorders. Background: Long-term whole-body vibration (WBV) exposure is associated with low back pain, sciatica, early spinal degeneration, and herniated lumbar disc. Methods: 247 male taxi drivers contributed 432 WBV measurements. The Nordic Musculoskeletal Questionnaire was used to access the lower back pain prevalence among the drivers. Each WBV measurement is being characterized by the ordinal number of frequency peaks, by the distribution of the peaks around 1-2 Hz, 4 Hz, and 10-20 Hz, and by the maximum amplitude. Four Hz was chosen as one of the key frequencies of the investigation because it is the natural resonant frequency of the spine. By analyzing the vibration frequency distribution and self-reported lower back pain with logistic regression, we hope to determine which vibration frequencies are most detrimental to the human spine.
