Study conducted to evaluate the StepWatch Activity Monitor (SAM) as a measure of activity for boys with Duchenne muscular dystrophy (DMD). The SAM is a small device, and it is worn on the user’s ankle. The SAM utilizes an accelerometer and a digital counter to record each step or swing of the leg. Sixteen boys with DMD and twenty controls participated in the study. The participants ranged from five to thirteen years of age. The participants wore the SAM for a period of 3 days during standard daily activities. The device proved to be a useful measure of the activity level of boys with DMD. Implications for further research are discussed.
