Abstrakt:	This study aimed to develop and assess a protocol for evaluating upper limb strength and its association with functional abilities in children and adolescents diagnosed with Duchenne muscular dystrophy (DMD). A cross-sectional study. Eleven male individuals diagnosed with DMD (aged 11 to 18 years). A systematic protocol for assessing the maximum voluntary isometric contraction (MVIC) of the upper limbs using grip and pull dynamometers was developed and conducted in conjunction with the Performance of Upper Limb (PUL) scale. Feasibility was evaluated by appraising the number of participants capable of successfully executing the strength test protocol. Correlations were conducted to examine the relationship between upper limb strength and PUL scores. The grip strength assessment was feasible for all participants, while the complete strength testing protocol was feasible for nine, excluding two individuals with non-ambulatory mobility. Significant correlations were found between overall upper limb strength and total PUL scores (rs = 0.742, p = 0.022), grip strength and distal PUL scores (rs=0.733, p = 0.010), shoulder abduction strength and PUL shoulder scores (rs=0.905, p = 0.005), and grip strength and overall PUL scores (rs=0.794, p = 0.004). The middle-level correlation was not statistically significant (rs=0.590, p = 0.094). The established strength test protocol demonstrated feasibility among ambulatory participants. However, alternative approaches are essential for those with limited ambulation. The study identified a robust correlation between upper limb strength and functional abilities. Further extensive studies are required to validate these findings. The present study is a part of a longitudinal intervention study registered at the ClinicalTrials.gov (NCT03963453).
