ABSTRACT
Objective To study the test-retest reliability in quantitative measurement of proprioception using Tecnobody rehabilitation system.Methods Nine healthy volunteers [4 males,5 females,averaged age (22.8 ±0.68) years] participated in three consecutive measurements on both feet by using Tecnobody rehabilitation system for computerized proprioceptive assessment.Standard error of measurement(SEM),correlation coefficient and intraclass correlation coefficient(ICC) obtained from the three consecutive measurements were used to analyze the Timeused in each measuring session,and the average track error (ATE) of the measurements.ResultsSEM values of Time in left foot and right foot were 3.07 ～ 3.83 and 6.65 ～ 8.44 respectively.ATE values in left foot and right foot were 1.33 ～ 1.97 and 1.39 ～ 1.91 respectively.The Time and ATE correlation coefficients of left foot / right foot were 0.919/0.6 and 0.808/0.831,respectively.The Time ICC values were 0.893/0.639 for left foot / right foot,respectively ; and the ATE ICC values were 0.716/0.734 for left foot / right foot,respectively. Conclusion The Tecnobody rehabilitation system provided a fairly good reliability in both relative andabsolute values in quantitative evaluation of proprioception in the feet.These data in a larger amount may be useful for setting up variables and the standard values of the local population for reference in proprioceptive rehabilitation.
