Abstract
Proprioception, one of the three sources of sensory feedback for maintaining balance in humans, can be disrupted due to factors such as aging, Parkinson's, diabetes, and sports injuries. The AMEDA device, commonly used in international research, has not been designed or utilized in Iran. The purpose of this study is to assess the reliability and validity of a newly developed proprioceptive acuity measuring device. Seventeen individuals with Parkinson's and 15 healthy individuals participated in the study. The device assessed the acuity of sense of motion in the dominant ankle of the participants. The intraclass correlation coefficient (ICC) and the area under the receiver operating characteristic curve (AUC of ROC) were used to determine the reliability and validity of the device. The ICC values for dorsiflexion and plantarflexion were 0.80 and 0.87 in healthy subjects, and 0.97 and 0.78 in people with Parkinson's. The AUC value for differentiating between healthy and Parkinson's groups was 0.94 for dorsiflexion and 0.92 for plantarflexion. The findings indicate that the device exhibits good reliability and validity, and can be utilized in future studies to measure sense of motion acuity in proprioception.
