- Determine the correlation between quantitative muscle ultrasound (QMUS), electrical impedance myography (EIM) and currently accepted measures of physical function.
- Determine the reliability of EIM measures performed in the home through use of a hand held device.
- Determine if QMUS and EIM can detect pre-clinical changes in Pompe disease.

All patients will undergo serial quantitative muscle ultrasound.
Device: Muscle ultrasound
Ultrasound images of limb muscles will be collected.
All patients will undergo serial electrical impedance myography measures.
Other: Electrical Impedance Myography
A painless current passes through the skin and surface electrodes are used to record the impedance through muscle.
- Percent change in muscle ultrasound echointensity as compared to baseline [ Time Frame: Baseline, 1-2 years ]
- Percent change in muscle electrical impedance myography as compared to baseline [ Time Frame: Baseline, 1-2 years ]
- Inter-rater reliability of muscle ultrasound and electrical impedance myography measures [ Time Frame: 1-2 years ]
