This paper is a review of the balance assessment methods currently used to evaluate standing balance. Most of the presently available instrumentation appears to be more suited to research laboratories than to routine clinical situations. Functional assessments of balance appear to be the quickest test to administer and do not require expensive equipment however only gross changes in balance can be detected making them suitable as a screening tool for identifying subject's needing more thorough evaluation. Force platforms appear to be most suited balance assessment instrumentation to the clinical situation since it produces a real time display and can detect small changes in subject's ability to maintain their balance making them suitable for thorough evaluations of balance and for monitoring patient's progress.

“…Hall effect sensors have a non-linear output, with calibration accomplished tradionally using a variety of curve-fitting techniques, including: 5th order polynomial (Weinhoffer et al, 1993), Gaussian curves (Ferrazzin et al, 1999), inverse tangent function (Cholewicki et al, 1997) and Newton's interpolating polynomial (Rodrı´guez et al, 2001). For more complex two-and three-dimensional applications, the increased degrees of freedom require an increased number of sensors and more advanced calibration techniques.…”
