Abstract:
Objective In the recovery process of stroke patients, the ability of maintaining standing and sitting position might have a great effect on the improvement of activity of daily living. There are few the methods which evaluate quantitatively and effectively the ability of position control ability in clinical practice. The aim of the study is to quantitatively evaluate the reliability of posturographic parameters based on the center of pelvis in different standing positions and walking activity.Methods From May to June, 2018, Seventy-nine healthy participants were enrolled. They were evaluated with iReGo, a walking assisstant robot, in three conditions: normal standing position, left/right standing position and walking 10 meters at an appropriate speed. The computer calculated the posturographic parameters automatically. The participants completed their second test one day after the first one.Results During normal standing position, the intra-class correlation coefficients (ICC) of average sway in coronal plane, average sway in sagittal plane, path length, and covered area were more than 0.70. During left standing position, ICC of all the above parameters were more than 0.70. During right standing position, ICC of all the above parameters were more than 0.49. When walking 10 meters at an appropriate speed, ICC of path length and covered area were more than 0.75. Comparing different standing positions, the normal standing position was more stable than the left/right standing position, and there was no difference between the left and the right standing positions.Conclusion Posturographic parameters based on the center of pelvis might be a reliable way to assess the position control ability in different standing positions and walking process.
