Abstract:

BACKGROUND: At home and abroad there are many studies of joint position in young people, but in older people, studies about test-retest reliability of joint position are lack.
OBJECTIVE: To determine the test-retest reliability of joint position in the different position of knee and ankle in older people.
METHODS: Ankle and knee joint position of 28 healthy older people was measured with passive replication test on the Biodex system 3 dynamometer. The absolute error angle of passive replication test was used to assess ankle position sense. The indicator of test-retest reliability of joint position was intraclass correlation coefficient (ICC).
RESULTS AND CONCLUSION: The test-retest reliability of joint position was modest in the different positions of both knee, and the values of ICC were from 0.851 to 0.973. The test-retest reliability of joint position was also modest in plantarflexion and dorsiflexion of both ankle, and the values of ICC were from 0.742 to 0.964. The absolute error angle of passive replication test in the left ankle was better than the right (P < 0.05); the test-retest reliability of the left ankle (ICC was from 0.870 to 0.964) was better than that of the right ankle (ICC was from 0.742 to 0.944). The test-retest reliability of joint position is good in the knee and ankle of older people, and the correlation of the left ankle is better than the right.
