Abstract

A method is provided for treating postural instability following a determination that a patient is experiencing postural instability. The method includes the steps of (a) providing a vibration table having a non-rigidly supported platform; (b) permitting the patient to rest on the non-rigidly supported platform for a predetermined period of time; and (c) repeating the steps (a) and (b) over a predetermined treatment duration. Step (b) includes the steps of (b1) measuring a vibrational response of the patient'"'"'s musculoskeletal system using a vibration measurement device; (b2) performing a frequency decomposition of the vibrational response to quantify the vibrational response into specific vibrational spectra; and (b3) analyzing the vibrational spectra to evaluate at least postural stability. Preferably, the predetermined period of time is approximately 10 minutes and the predetermined treatment duration is at least four weeks.

Claims
