Test–retest reliability of the joint position sense assessment. The test–retest reliability was investigated in a subset of 15 mid-aged subjects, who performed the joint position sense test on 3 consecutive days (day one (A); day two (B); day three (C)) within 1 week.

Notes: All calculations were based on the summed data of the three subtests (sum). Test–retest reliability was acceptable for the number of errors (Cronbach’s alpha = 0.787) and the weight of errors (Cronbach’s alpha = 0.761); moreover, the reliability of the direction of errors was good (Cronbach’s alpha 0.833).
