OBJECTIVE: To evaluate the sensitivity and specificity of the Intelligent Device
for Energy Expenditure and Activity (IDEEA) monitor in detecting functional
activities in young people with cerebral palsy (CP). DESIGN: Validation study.
SETTING: Two identical data collections completed 1 week apart at a gait
laboratory. PARTICIPANTS: Twenty-five young people with CP and 30 able-bodied
(AB) peers (age 8-25 y; mean age CP 14.1 y, Gross Motor Function Classification
System Level I-III; mean age AB, 14.2 y). INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: Each participant completed 5 functional activities (sitting,
lying, standing, walking, and stairs), with the monitor attached. The sensitivity
and specificity of the monitor in detecting each activity was calculated by
comparison to a written timed report. RESULTS: Sitting, lying, and standing were
detected with median 100% sensitivity in both participant groups and across both
testing sessions. Accuracy of walking detection was reduced compared with static
activities (P<.05) across the 2 sessions and groups. The CP group had a
significantly higher number of participants where the activity was not detected
with 100% sensitivity (lie: 18% CP, 5% AB, P<.04; stand: 12% CP, 0% AB, P<.02;
walk: 96% CP, 81% AB, P<.03). Stair climbing was detected in only half of the 12
participants with CP who could achieve the task. The IDEEA demonstrated high
specificity (range, 97%-100%) for both participant groups. CONCLUSIONS: The IDEEA
activity monitor had high levels of sensitivity and specificity in determining
everyday static activities in participants with CP, with greater difficulties in
detecting dynamic activities of walking and stair climbing.
