There is, however, little evidence to show that wrist-based actigraphy measures correlate with functional decline, and no consensus on how best to implement actigraphy. We report on the use of wrist actigraphy to show decreased activity in patients compared to controls, and compared the utility of wrist- and hip-based actigraphy for assessing functional decline in patients with MND.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>In this multi-cohort, multi-centre, natural history study, wrist- and hip-based actigraphy were assessed in 139 patients with MND (wrist, <jats:italic>n\u2009=\u2009<\/jats:italic>97; hip, <jats:italic>n\u2009=\u2009<\/jats:italic>42) and 56 non-neurological control participants (wrist, <jats:italic>n\u2009=\u2009<\/jats:italic>56).
