Hi,
We plan to monitor stroke patients' activity using the Philips Actiwatch 2 Activity monitor. Would it be better to fit the monitor on patients' dominant (unaffected) or non-dominant (affected) wrists? Any relevant papers about this?
Thank you,
Hao-Yu
Dear Hao-Yu Shih,
If You are interested in the patient's overall activity during the improvement of his/her ADLs, use the unaffected wrist. Use the affected wrist, if You want to know how much the patient uses his/her paretic arm in everyday life, f.i. to validate a forced use paradigm. If You are interested in the change of activity ratio between both arms, well You should have 2 actiwatches or 1 actiwatch on the affected arm and software, which can separate the data from the watch in two parallel data streams for near field activity (= affected arm) and far field activity form the whole rest of the body. - it might be possible by a wavelet analysis of the signal.
Yours
