Does the RT3 accelerometer spell the end of pen-and-paper questionnaires/

Here is a great thoughtthe arduous task of filling out boring questionnaires may soon be obsolete! Well, at least for people with multiple sclerosis (MS) whose activity levels must be monitored by doctors. Thanks to the RT3 accelerometer, MS patients can discreetly monitor their activity without the hassle of keeping a journal or completing activity questionnaires. The RT3 is a small triaxial monitor that measures the amount of exercise its wearer performs in a given amount of time. Put simply, the RT3 is a pedometer that measures acceleration along three anatomical axes; not only does it measure the amount of exercise, but it also measures the intensity of movement. The RT3 is touted as being the most accurate of its kind, but, how accurate is it really" Also curious, researchers at the Centre for Physiotherapy Research at the University of Otago in New Zealand conducted a pilot study to investigate the test-retest reliability of the RT3. The study, which used 10 participants with a definite diagnosis of MS and 10 nondisabled adults as the control group, concluded that, despite some possible measurement errors, the RT3 consistently measures walking. Good-bye pens and paperFor more information about this study, read Reliability of RT3 accelerometer for measuring mobility in people with multiple sclerosis: Pilot study in this months JRRD at www.rehab.research.va.gov/jour/07/44/4/pdf/hale.pdf.
