Background: This study aimed to investigate the use of actigraphy (accelerometry) to measure disuse of the impaired arm in acute stroke patients. We correlated the National Institute of Health Stroke Scale (NIHSS) and the Fugl-Meyer Assessment arm section (FMA) findings with actigraphic data as a measure of validity. Methods: Thirty-nine acute ischemic stroke patients were included within 1 week after stroke onset. At inclusion, motor deficits were assessed by the NIHSS, FMA and 48-hour actigraphic recordings of both wrists were performed. Results: Moderate but highly significant correlations (Spearman’s rho) between actigraphic recordings and total NIHSS (ratio r = –0.59 and activity of impaired arm r = –0.75; p < 0.001) and FMA (ratio r = 0.54 and activity of impaired arm r = 0.69; p < 0.001) scores were found. Based on actigraphic motor activity scores, ROC curves were calculated following dichotomization of the population based on NIHSS = 7 and FMA = 45, showing good sensitivity and specificity, with negative predictive value of 100% and positive predictive value of 91% for the ratio variable. Conclusions: Moderate but highly significant correlations were found between actigraphy and the stroke scales NIHSS and FMA. Actigraphy was able to reliably discriminate less impaired from more impaired stroke patients with excellent sensitivity and specificity values. Actigraphy is a simple, valid, objective and reliable clinical research tool that can be used to determine motor impairment of the upper limb in stroke patients.

“…Accelerometers provide a reliable and objective way to assess real-world UE function of individuals with stroke. [11][12][13][14][15] Cross-sectional studies have found that early poststroke UE wrist accelerometer measures correlate to stroke severity 16 and motor impairment of the affected UE. 16,17 More so, correlations have been found between accelerometer readings to the self-report MAL (r 5 .81-.90) for 169 individuals 3-9 months after stroke.…”

“…In fact, wrist actigraphy has proven useful in assessing activity patterns in sleep disturbances [1,7], movement disorders [16], malignant diseases [12] and psychiatric illnesses [15]. Quantitative movement recording over 3 days has been reported to reliably evaluate movement activity in sleep as well as movement activity reduction resulting from hemiparesis [8,25]. Thus, accelerometry measures the net effect of all factors influencing spontaneous arm movement activity including those that reduce movement activity below the normal level.…”

The factors determining recovery from hemiparetic stroke are manifold. We studied spontaneous arm movement activity in the acute phase after stroke as a predictor of recovery. Included in this prospective study were 25 patients (63 ± 10 years; 9 women, 16 men) with acute middle cerebral artery stroke and 7 control patients without neurological disease (61 ± 14 years; 3 women, 4 men). Movement activity was measured continuously for 4 days in both arms using Actiwatches and analysed off-line. Movement activity of the nonaffected arm ranged from <10 to >16 h per day in the stroke patients. Nine stroke patients with an initial decline in arm movement activity showed no increase in movement activity in either arm over 4 days after stroke, and the other 16 patients improved steadily after admission (p < 0.003). C-reactive protein was elevated in the non-recovering patients (4.4 ± 4.9 mg/dl) related to a low number of waking hours (r = -0.512, p < 0.01). Stroke severity, location and treatment, as well as arterial blood pressure (162 ± 21 mmHg) and body temperature (36.9 ± 06 °C) were not different among the groups. The impairment was still different among the two groups 3 months after stroke. Our results support the notion that in the acute stage after middle cerebral artery stroke there are patients with a secondary decline in general motor activity related to an enhanced sleep demand as assessed with accelerometry. This impairment was related to elevated C-reactive protein.
