Not all stroke units are the same - A comparison of physical activity patterns in Melbourne, Australia, and Trondheim, Norway
ABSTRACT Very early mobilization may be one of the most important factors contributing to the favorable outcome observed from a stroke unit in Trondheim, Norway. The aims of this study were to (1) describe and compare the pattern of physical activity of patients with stroke managed in a stroke unit with specified mobilization protocols (Trondheim) and those without in Melbourne, Australia; and (2) identify differences in activity according to stroke severity between the 2 sites.
Melbourne patients were recruited from 5 metropolitan stroke units. Trondheim patients were recruited from the stroke unit at University Hospital, Trondheim. All patients <14 days poststroke were eligible for the study. Patients receiving palliative care were excluded. Consenting participants were observed at 10-minute intervals from 8:00 am to 5:00 pm over a single day. At each observation, patient location, activity, and the people present were recorded. Negative binomial regression analyses were undertaken to assess differences in physical activity patterns between stroke units in the 2 cities.
Patients in Melbourne and Trondheim had similar baseline characteristics. Melbourne patients spent 21% more time in bed and only 12.2% undertook moderate/high activity (versus 23.2% in Trondheim, P<0.001). This difference was even more pronounced among patients with greater stroke severity. The incidence rate ratio for time spent doing standing and walking activities in Melbourne was 0.44 (95% CI: 0.32 to 0.62) when compared with Trondheim.
Higher activity levels were observed in Trondheim patients, particularly among those with more severe strokes. A greater emphasis on mobilization may make an important contribution to improved outcome. Further investigation of this is warranted.

ABSTRACT: Background. If a simple system of instrumented monitoring was possible early after stroke, therapists may be able to more readily gather information about activity and monitor progress over time. Our aim was to establish whether a device containing a dual-axis accelerometer provides similar information to behavioural mapping on physical activity patterns early after stroke. Methods. Twenty participants with recent stroke ≤2 weeks and aged >18 were recruited and monitored at an acute stroke ward. The monitoring device (attached to the unaffected leg) and behavioural mapping (observation) were simultaneously applied from 8 a.m. to 5 p.m. Both methods recorded the time participants spent lying, sitting, and upright. Results. The median percentage and interquartile range (IQR) of time spent lying, sitting, and upright recorded by the device were 36% (15-68), 51% (28-72), and 2% (1-5), respectively. Agreement between the methods was substantial: Intraclass Correlation Coefficient (95% CI): lying 0.74 (0.46-0.89), sitting 0.68 (0.36-0.86), and upright 0.72 (0.43-0.88). Conclusion. Patients are inactive in an acute stroke setting. In acute stroke, estimates of time spent lying, sitting, and upright measured by a device are valid.10/2013; 2013:460482. DOI:10.1155/2013/460482

ABSTRACT: Background. Comprehensive stroke unit care, incorporating acute care and rehabilitation, may promote early physical activity after stroke. However, previous information regarding physical activity specific to the acute phase of stroke and the comprehensive stroke unit setting is limited to one stroke unit. This study describes the physical activity undertaken by patients within 14 days after stroke admitted to a comprehensive stroke unit. Methods. This study was a prospective observational study. Behavioural mapping was used to determine the proportion of the day spent in different activities. Therapist reports were used to determine the amount of formal therapy received on the day of observation. The timing of commencement of activity out of bed was obtained from the medical records. Results. On average, patients spent 45% (SD 25) of the day in some form of physical activity and received 58 (SD 34) minutes per day of physiotherapy and occupational therapy combined. Mean time to first mobilisation out of bed was 46 (SD 32) hours post-stroke. Conclusions. This study suggests that commencement of physical activity occurs earlier and physical activity is at a higher level early after stroke in this comprehensive stroke unit, when compared to studies of other acute stroke models of care.08/2013; 2013:438679.

ABSTRACT: Background. Common models of acute stroke care include the acute stroke unit, focusing on acute management, and the comprehensive stroke unit, incorporating acute care and rehabilitation. We hypothesise that the rehabilitation focus in the comprehensive stroke unit promotes early physical activity and discharge directly home. Methods. We conducted a two-centre prospective observational study of patients admitted to a comprehensive or acute stroke unit within 14 days poststroke. We recruited 73 patients from each site, matched on age, stroke severity, premorbid function, and walking ability. Patient activity was measured using behavioural mapping. Therapy activity was recorded by therapist report. Time to first mobilisation, discharge destination, and length of stay were extracted from the medical record. Results. The comprehensive stroke unit group included more males, fewer partial anterior circulation infarcts, more lacunar infarcts, and more patients ambulant without aids prior to their stroke. Patients in the comprehensive stroke unit spent 14.4% more (95% CI: 8.9%-19.8%; P < 0.001) of the day in moderate or high activity, 18.5% less time physically inactive (95% CI: 5.0%-32.0%; P = 0.008), and were more likely to be discharged directly home (OR 3.7; 95% CI 1.4-9.5; P = 0.007). Conclusions. Comprehensive stroke unit care may foster early physical activity, with likely discharge directly home.01/2013; 2013:498014. DOI:10.1155/2013/498014
