Abstract
Background: Knee osteoarthritis is a common disease of the locomotor system, characterized by cartilage degeneration. Pain and joint stiffness are the most outstanding symptoms. Coordination and proprioception are important mechanisms for joint stability, but are still difficult to measure. The Mr. Cube is a new apparatus that provides this possibility. Measuring coordination and proprioception could be interesting for scientific research or for use in clinical practice. For that the purpose of this study is to determine the validity and test-retest reliability of the coordination- and proprioception test of the Mr. Cube. Methods: Reliability and validity study which was executed at the University Medical Centre Groningen (UMCG) and at the Paramedic Centre for Rheumatology and Revalidation (PCRR) in Groningen. Patients between 50 and 75 years with knee osteoarthritis were included at the osteoarthritis outpatient clinic of the UMCG and at PCRR. Because of the test-retest design, participants were tested twice with an interval of 1-2 weeks. Participants performed the Mr. Cube’s coordination- and proprioception test and, to assess validity, performed a Get-up-and-Go test and filled in the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire. Those tests were executed to determine the agreement between thee GUG and the KOOS, in which coordination and proprioception are important parameters, and the results of the coordination- and proprioception test of the Mr. Cube. Intraclass Correlation Coefficients (ICC) and Bland & Altman analyses were used to determine the test-retest reliability. ICC’s are used to determine relative reliability, Bland & Altman analysis is used to determine absolute reliability. Spearman’s Rho correlations were used to determine validity between the Mr. Cube and the Get-Up-and-Go test and the KOOS. Results: Mr. Cube’s reliability study showed ICC’s in the range of 0,71-0,82 for the coordination test. Bland and Altman analysis found a systematic bias for the coordination test. The bias showed a significant better performance at the second measuring moment in comparison with the first measuring moment. The proprioception test showed ICC’s in the range of 0,41-0,70 and had no systematic bias. Mr. Cube’s validation study gave Spearman’s Rho Correlation Coefficients in the range of -0,26 till 0,23 for the coordination test and in the range of -0,24 – 0,17 for the proprioception test. Discussion: The coordination test of the Mr. Cube possesses good test-retest reliability, but has a systematic bias. The coordination test therefore has low absolute reliability, probably due to a learning effect. The proprioception test of the Mr. Cube possesses good test-retestreliability. The agreement between the results of the coordination- and proprioception test of the Mr. Cube with the GUG and the KOOS is low, which is in line with our hypothesis. Further research is needed to determine Mr. Cube’s validity.
