We propose to compare the reliability of CQMS vs. HHM in the DMD population. The importance of this study is to be able to compare the results of clinical trials done by different networks using distinct strength endpoints. If results indicate a distinct difference in reliability of one tool over the other, a standardized tool could be established for research groups throughout the world to interpret strength in the context of clinical trials. If the results indicate minor differences then it would be possible to interpret and compare/contrast strength measurements used in different studies.
Understanding the relationship between the HHM vs CQMS will help us examine other surrogate measures capable of predicting functionality that are based on strength measurements.

- Compare the inter and intra rater reliability of HHM and CQMS by measuring Elbow and Knee Flexor/Extensor Strength in children ages 6-18 diagnosed with DMD tested by experienced clinical evaluators in both HHM and CQMS. [ Time Frame: two-day visit ]Muscle groups will be tested in a standardized order 1. Knee extension 2. Knee flexion 3. Elbow Flexion 4. Elbow extension with all tests sequencing following a right to left pattern. This will reduce assessment bias and the impact of muscle fatigue per muscle group. Study participants are randomized to two different sequences of four assessments, one sequence performed on one testing day (Visit 1) and another on a different testing day (Visit 2).
