For example, brushing one's teeth is neither work nor leisure; scholars differ in their classifications of activities such as eating a meal, shopping, repairing a car, attending a religious ceremony, or showering (various individuals may or may not classify such activities as leisure).
It might be that the classification of activity was not sensitive enough to evaluate the effect of particular kinds of physical activity on later OA.
The accelerometer provides a measure of the frequency, intensity and duration of physical activity and allows classification of activity levels as sedentary, light, moderate and vigorous.
This simple PA question may be useful in studies of older adults where PA is not the primary focus, but a brief classification of activity levels is needed.
The accelerometer provides a measure of the frequency, intensity and duration of physical activity and allows classification of activity levels as sedentary, light, moderate-to-vigorous physical activity (MVPA).
The activity or classification of activity referred to by the question is not as important as whether or not planning is required and/or participation is disrupted or limited.
Unique to this instrument is the idea that the activity or classification of activity referred to by the questions is not as important as whether or not planning is required and/or participation is disrupted or limited.
The conversation leads to identification of the primary goal within the five main areas (see above) and specific subsidiary goals and described cf. International Classification of Functioning, Disability and Health ICFF) classification of activity or participation level, supplemented by specific milestones [ 23].
Online classification of activity and pre-processing steps were done with the DataWave Discovery system (DataWave Technologies, Loveland, CO) at Oxford and Spike 2 (Cambridge Electronic Design Ltd., Cambridge, UK) data acquisition program at NIH. Area V5/MT was approached posteriorly through the recording chamber in incremental steps of about 100 µm.
