Lumbar Proprioception in Lower Back Pain Patients Versus Healthy Subjects : a Comparative Study on the Effects of Low- and High-frequency Muscle Vibrations

The primary objective of this study is to compare the lumbar proprioception of patients with chronic back pain to that of healthy volunteers during low- and high-frequency muscle vibration. The order of measures (low frequency of vibration, high frequency vibration and no vibration) is randomized in a cross-over design. Patients and volunteers are matched by age and body mass index.
