Abstract

Background: The current investigation examined the inter- and intra-tester reliability of knee joint angle measurements using a flexible Penny and Giles BiometricÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â® electrogoniometer. 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 intertester 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 0.58ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“0.71 in supine, 0.68ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“0.79 in sitting and 0.57ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“0.80 in standing. The standard error of measurement between testers was less than 3.55ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â° and the limits of agreement ranged from -12.51ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â° to 12.21ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â°. Reliability coefficients for intra-tester reliability (ICC[3,10]) ranged from 0.75ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“0.76 in supine, 0.86ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“0.87 in sitting and 0.87ÃƒÂ¢Ã¢"šÂ¬Ã¢â‚¬Å“0.88 in standing. The standard error of measurement for repeated measures by the same tester was less than 1.7ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â° and the limits of agreement ranged from -8.13ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â° to 7.90ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â°. The second study showed that using a more detailed electrogoniometer attachment protocol reduced the error of measurement between testers to 0.5ÃƒÆ’Ã¢â‚¬Å¡Ãƒ"šÃ‚Â°. Conclusion: Using a standardised protocol, reliable measures of knee joint angles can be gained in standing, supine and sitting by using a flexible goniometer.
