Abstract
Introduction
Community-dwelling stroke survivors tend to become less physically active over time.
There is no ‘gold standard’ to measure walking activity in this population. Assessment
of walking activity generally involves subjective or observer-rated instruments. Objective
measuring with an activity monitor, however, gives more insight into actual walking
activity. Although several activity monitors have been used in stroke patients, none
of these include feedback about the actual walking activity. FESTA (FEedback to Stimulate
Activity) determines number of steps, number of walking bouts, covered distance and
ambulatory activity profiles over time and also provides feedback about the walking
activity to the user and the therapist.
Aim
To examine the criterion validity and test-retest-reliability of the FESTA as a measure
of walking activity in patients with chronic stroke. To target the properties of the
measurement device itself and thus exclude effects of behavioral variability as much
as possible evaluation was performed in standardized activities.
Methods
Community-dwelling individuals with chronic stroke were tested twice with a test-retest
interval varying from two days to two weeks. They performed a six-minute walk test
and a standardized treadmill test at different speeds on both testing days. Walking
activity was expressed in gait parameters: steps, mean-step-length and walking distance.
Output data of the FESTA on the treadmill was compared with video analysis as the
criterion measurement. Intraclass Correlations Coefficients (ICCs) and Mean Relative
Root Squared Error (MRRSE) were calculated.
Results
Thirty-three patients were tested to determine criterion validity, 27 patients of
this group were tested twice for test-retest reliability. ICC values for validity
and reliability were high, ranging from .841 to .972.
Conclusion
This study demonstrated good criterion validity and test-retest-reliability of FESTA
for measuring specific gait parameters in chronic stroke patients. FESTA is a valid
and reliable tool for capturing walking activity measurements in stroke, and has applicability
to both clinical practice and research.
