Abstract

Pompe disease is a rare multisystem genetic disorder that characterized by a deficiency of the lysosomal enzyme acid alphaglucosidase and cytoplasmic glycogen accumulation causing damage that leads to muscle weakness. This study aim is to evaluate the muscle MRI pattern of twelve adults with late onset Pompe disease and twelve sex- and age-matched healthy controls (Age range 19-59) for feature extraction which will be used to identify and classify functioning and non-functioning muscles. A training procedure was implemented using an Exercise Dynamometer device to stimulate the muscle for maximal contraction, MRI images data was used to compare the three flexor muscles in the lower limb function. MRI images data of biceps femoris (BF) muscle, Semitendinosus (ST) muscle, semimembranosus (SM) muscle before and after exercise (base, 30 min, 24 hours) was measured. We performed and quantified T2 relaxation data of flexor muscles, and all data analyzed using repeated measure ANOVA to compare within related groups of the independent variable time (Base, 30M, 24H). According to our results, the significantly lower T2 value in the ST muscle of controls was observed (base=43ms, 30min=48ms, 24h=43ms; P < 0.05), but the change in SM muscle and BF muscle were not significant. In patients, we detected significantly higher T2 value in SM muscle evolve over time (base=129ms, 30min=132ms, 24h=128ms; P < 0.05) compared to the controls, but ST muscle neither BF muscle doesn't show significant change. As a conclusion, we can say that in Pompe patients the SM muscle can only react to the exercise apparently and shows us an activity in affected muscle cells, compared to the BF and ST muscle not shown any activity, that�s mean perhaps the Pompe disease change the muscle cells structure to interact to the exercise.
