Psychometric properties of lift and carry test in assessing people with stroke

Objective: To investigate the psychometric properties of the Lift and Carry Test (LCT) time in people with stroke. Design: Cross-sectional design. Setting: University based neurorehabilitation laboratory. Participants: Twenty-four people with stroke and 24 healthy controls. Outcome measures: Lift and Carry Test (LCT), Fugl-Meyer Assessment of upper extremity and lower extremity, ankle dorsiflexor and plantarflexor muscle strength, Berg Balance Scale (BBS), Timed Up and Go (TUG) and Community Integration Measure. Results: The mean LCT time (29.70s) in people with stroke was more than double of that in healthy controls (13.70s). The LCT showed excellent intra-rater, inter-rater and test–retest reliability [intraclass correlation coefficient (ICC) = 0.943–1.000]. The LCT times demonstrated a significant negative correlation with the BBS score (r_s = −0.771) and significant positive correlations with the TUG times (r_s = 0.933). There was no significant correlation between LCT times and FMA score (p > 0.05). An optimal cut-off LCT time of 15.48 s (sensitivity = 95.8%, specificity = 87.5%) was identified to differentiate between people with stroke and healthy controls (area under the curve = 0.957). Conclusion: LCT is an excellent clinical test for examining advanced functional ability in people with stroke and distinguishing people with stroke from healthy controls.
