Cross-cultural Adaptation and Multi-centric Validation of the Motor Function Measure Chinese Version (MFM-32-CN) for Patients with Neuromuscular Diseases

Abstract: Aim: This study aims to produce a Chinese translation and adaptation of the MFM-32 and examine its measurement parametric properties in Chinese population with neuromuscular diseases. Methods: The MFM-32-CN was validated by testing reliability, internal consistency, and construct validity. Results: The Interrater and intrarater reliability of MFM-32-CN were moderate to excellent for each item, and excellent for the total score and the subscores. The internal consistency was high for the global scale and subscales. The total score was strongly related to the VAS and Vignos grade, and to a lesser degree to the Brooke grade. The discriminant validity was good. Conclusion: MFM-32-CN has satisfactory reliability, internal consistency, convergent validity and discriminant validity in youngsters with DMD, and good psychometric properties have also been observed for the whole population tested combining different NMD groups, but future study with a larger number of participants in each disease group is needed to confirm the present results.

İnter-rater and intra-rater reliability of the extended TUG test in elderly participants.

Abstract: To analyse the reliability, variance and execution time of the Extended Timed Up and Go (Extended TUG) test in three age groups of elderly participants (G1: 55–64 years; G2: 65–74 years; G3: 75–85 years). An analytical cross-sectional study of 114 recruited participants (63 women) of average age 70.17 (± 7.3) years was undertaken. Each participant performed the Extended TUG three consecutive times, with a rest break between tests of 120 s. Both the intragroup and intergroup reliability of the measurements in the Extended TUG were analysed. The reliability of the Extended TUG test is excellent for the first and second decades but drops down to good for the third decade. Specifically, intragroup reliability ranged from 0.784 for G3 to 0.977 for G1 (G2 = 0.858). Intergroup reliability, compared with intragroup reliability, was slightly lower, ranging between 0.779 for G3 and 0.972 for G1 (G2 = 0.853). The reliability of the Extended TUG test progressively decreases with increasing age, being excellent for the younger age groups and good for the oldest age group.

Assessing the dynamic changes in vitiligo: reliability and validity of the Vitiligo Disease Activity Score (VDAS) and Vitiligo Disease Improvement Score (VDIS)

Abstract: The assessment of the individual evolution of vitiligo is important for therapeutic decision making in daily practice. A fast, simple and validated physician‐reported score to assess clinical changes in depigmentation over time in separate parts (activity and improvement) is currently missing.
