Comparison of trunk strength measurements between two different isokinetic devices used at clinical settings.
Intradevice reliability of isokinetic trunk strength measurements has been studied frequently , but no evidence is available on interdevice reliability . This motivated the present study , in which two isokinetic devices , the Ariel 5000 and Lido Multi-Joint II , were compared in a sample of 41 subjects ( 20 healthy and 21 low back pain subjects ) . The measurements were made in a r and om order with both machines . The results showed that the two isokinetic machines gave quite different results in trunk flexion-extension strength measurements . A statistically significant difference was present in the average peak torques between the two devices , with the exception of flexion at low angular velocity ( 60 degrees/s ) , and the correlations between the two measurements were low . The results were assumed to be more of a reflection of the interdevice variations ( hardware and software , attachment of the subject ) than of learning effects or other phenomena . We conclude that isokinetic trunk-muscle strength test results with the Ariel and Lido are device specific , and one can not automatically compare results obtained from different devices with each other
