Psychometric Properties of the Trail Walking Test for People With Stroke

Abstract

ObjectiveTo investigate (i) the inter-rater and test–retest reliability of the trail walking test (TWT) and the minimum detectable change in the TWT completion time; (ii) the correlations between the TWT completion time and stroke-specific impairments; and (iii) the cutoff TWT completion time to distinguish between people with stroke and healthy older adults according to dual-tasking ambulation ability.DesignCross-sectional study.SettingUniversity-based rehabilitation center.ParticipantsIn total, 104 people with stroke and 53 healthy older adults.Main Outcome MeasuresThe TWT, the Fugl–Meyer Assessment of Lower Extremity (FMA-LE), the ankle muscle strength test, the limit of stability (LOS) test, the Berg Balance Scale (BBS), the Timed Up and Go test (TUG), and the Community Integration Measure (CIM).ResultsThe mean TWT completion time in subjects with stroke was 124.906 s. The TWT demonstrated excellent inter-rater reliability [intraclass correlation (ICC) = 0.999] and good test–retest reliability (ICC = 0.876) in people with stroke. The TWT performance demonstrated significant negative correlations with the FMA-LE scores (r = −0.409), LOS movement velocity (affected and unaffected sides; r = −0.320 and −0.388, respectively), and LOS endpoint excursion (affected and unaffected sides; r = −0.357 and −0.394, respectively); a significant positive correlation with the LOS reaction time (affected side; r = 0.256); a moderate negative correlation with the BBS scores (r = −0.72); and an excellent positive correlation with the TUG completion time (r = 0.944). The receiver operating characteristic curve analysis revealed that an optimal cutoff of 69.61 s for the TWT completion time had an outstanding diagnostic power to distinguish between people with stroke and healthy older adults (area under the curve = 0.919) with high sensitivity (88.5%) and specificity (83.0%).ConclusionResults of our preliminary study demonstrated that the TWT is a reliable, valid, sensitive, and specific clinical test for evaluating dual-tasking ambulation ability in people with stroke aged 45 years or above and without cognitive impairments. It can differentiate the dual-tasking ambulation ability between people with stroke and healthy older adults.

Psychometric properties of the Chinese version of the Arm Activity Measure in people with chronic stroke

“…The Trail Walking Test (TWT) simultaneously measures motor (locomotion and turning) and cognitive functions (visual search function and short-term memory) ( 29 ). In the TWT, participants are required to walk to 15 numbered cones sequentially at their normal walking speed ( 30 ). One trial was performed by each participant, and the completion time was recorded.…”

“…One trial was performed by each participant, and the completion time was recorded. Good test–retest reliability (ICC = 0.88) and excellent inter-rater reliability (ICC = 0.99) have been found for the TWT in people with chronic stroke ( 30 ).…”

Effects of dry needling intervention on lower limb dysfunction after stroke: study protocol for a randomised controlled trial

“…The higher the score is, the better the lower limb motor function on the hemiplegic side is.Intra-class correlation coefficient (ICC)is the principal measurement of reliability. The FMA-LE has been shown to have excellent intrarater reliability (ICC=0.93) and good test–retest reliability (ICC=0.868) in patients who had a poststroke 26. The scale will be evaluated at baseline, at 24 hours after treatment, at 2 weeks after treatment and at 3-month follow-up.…”

Psychometric properties of the Chinese (Cantonese) version of the Upper Extremity Functional Index in people with chronic stroke

“…Future studies should include participants with lower levels of functional mobility to increase the generalisability of our results to the stroke population. Second, stroke incidence is associated with age, doubling with each decade after 55 years (61), only people aged ≥ 50 years were recruited in this study. Thus, the results in our study only apply to those participants who fulfilled our inclusion criteria.…”
