Shortening the AMEDA Test: Still Reliable, Less Exhausting

You know how some tests can be super long and boring? That's where the Active Movement Extent Discrimination Assessment (AMEDA) comes in. This test checks how well your legs sense movements and touch, which is called proprioception. Researchers wanted to make this test faster to help people stay focused and reduce mistakes. They compared a 50-repetition version (Group 1) with a shorter 25-repetition one (Group 2). Both versions turned out to be equally reliable, with only minor differences. The shorter test might be just as good, making it a great option for quick check-ups. Before, people thought longer tests were better. But now, we see that a shorter test can be just as useful. It might even help athletes who don't have much time. The test measures how well your body responds to movement, which is key for sports. So, why not make it quicker?First, researchers used the Spearman-Brown Adjusted Pearson correlation (r) to compare the two versions. Group 1 had an r of 0. 83, while Group 2 had 0. 85. Both scores showed that the tests were reliable. They also used Bland-Altman Plots and Intraclass Correlation Coefficients (ICC) to check the results. The ICC for Group 1 was 0. 83, and for Group 2, it was 0. 85. The Minimal Detectable Change at 90% confidence (MDC90) was 0. 082 for Group 1 and 0. 086 for Group 2. Even with all groups combined, the shorter test was still reliable. So, what does this mean? It shows that we might not need such long tests. People can get tired or lose focus, which can lead to mistakes. A shorter test could help avoid this problem. Plus, it saves time, which is always a good thing!
