The physical asymmetries associated with a prosthesis raises
the question of validity of the Sensory Organization Test (SOT) measures
(equilibrium score (ES) and strategy score (SS)) in lower limb amputees. This
study explores the validity of these measures in transtibial amputees by
correlating with their corresponding centre of pressure (COP) excursion/velocity
measures. TECHNIQUE : Fifteen transtibial amputees (69.5 +/- 6.5 years) completed
three trials for each of the six SOT conditions. DISCUSSION : The Spearman's rank
correlation coefficients between ESs and global COP excursion/velocity measures
ranged from 0.52 to 0.71 for Conditions 1, 4 and 5, 0.79 to 0.85 for Conditions 2
and 3, and 0.39 to 0.43 for Condition 6. The coefficients for SSs ranged between
0.78 and 0.97 for Conditions 1 to 5 and 0.55 to 0.67 for Condition 6. The
corresponding sound and prosthetic side COP variables demonstrated varying
strengths of association with ES and SS. Clinical relevance Of the two clinical
measures examined, the SSs are strongly reflective of COP excursion/velocity
measures and these findings have application in the interpretation of SOT when
evaluating balance in transtibial amputees.
