Background The current investigation examined the inter- and intra-tester reliability of knee joint angle measurements using a flexible Penny and Giles Biometriclectrogoniometer. The clinical utility of electrogoniometry was also addressed. Methods The first study examined the inter- and intra-tester reliability of measurements of knee joint angles in supine, sitting and standing in 35 healthy adults. The second study evaluated inter-tester and intra-tester reliability of knee joint angle measurements in standing and after walking 10 metres in 20 healthy adults, using an enhanced measurement protocol with a more detailed ...

The clinical utility of electrogoniometry was also addressed. Methods The first study examined the inter- and intra-tester reliability of measurements of knee joint angles in supine, sitting and standing in 35 healthy adults. The second study evaluated inter-tester and intra-tester reliability of knee joint angle measurements in standing and after walking 10 metres in 20 healthy adults, using an enhanced measurement protocol with a more detailed electrogoniometer attachment procedure. Both inter-tester reliability studies involved two testers. Results In the first study, inter-tester reliability (ICC[2,10]) ranged from 0.58-0.71 in supine, 0.68-0.79 in sitting and 0.57-0.80 in standing. The standard error of measurement between testers was less than 3.55ࠡnd the limits of agreement ranged from -12.51࠴o 12.21Reliability coefficients for intra-tester reliability (ICC[3,10]) ranged from 0.75-0.76 in supine, 0.86-0.87 in sitting and 0.87-0.88 in standing. The standard error of measurement for repeated measures by the same tester was less than 1.7ࠡnd the limits of agreement ranged from -8.13࠴o 7.90The second study showed that using a more detailed electrogoniometer attachment protocol reduced the error of measurement between testers to 0.5ஊ Conclusion Using a standardised protocol, reliable measures of knee joint angles can be gained in standing, supine and sitting by using a flexible goniometer.
