Development of the Chinese Version of TEMPA and Its Reliability and Validity in Stroke Patients
Abstract
Background Functional assessment is a foundation for rehabilitation treatment, which contributes to the development of the rehabilitation program and the improvement of rehabilitation outcomes. However, there are only few assessment scales with unvaried domains for upper extremity function after stroke. Objective To develop the Chinese version of Upper Extremity Performance Test (TEMPA) and to explore its reliability and validity in stroke patients. Methods We translated and revised the English version of TEMPA to a Chinese version according to the Brislin's translation procedures of forward-translation, back-translation, review, cultural adaptation and a pre-test. Then from August 2021 to January 2022, the Chinese version of TEMPA, Fugl-Meyer Assessment of Upper Extremity (FMA-UE) and Simple Test for Evaluating Hand Function (STEF) were used to evaluate the upper limb function of 40 patients with stroke recruited from Department of Rehabilitation, Tangshan Workers' Hospital. One week after the first evaluation, the Chinese version of TEMPA (TEMPA-C) was used to evaluate their upper limb function again. The test intra-rater reliability and inter-rater reliability of each dimension of the TEMPA-C were tested by intraclass correlation coefficient (ICC). The internal consistency reliability of TEMPA-C was tested by Cronbach's α. The total score of each dimension and item score of TEMPA-C and the scores of FMA-UE and STEF were analyzed by Pearson correlation analysis to test criterion validity of TEMPA. Results The ICC for the intra-rater reliability and the inter-rater reliability of the TEMPA-C functional rating total score was 0.992, and 0.982, respectively. The ICC for the intra-rater reliability and the inter-rater reliability of the TEMPA-C task analysis total score was 0.998 and 0.999, respectively. The Cronbach's α of the TEMPA-C functional rating dimension was 0.858. The score for performing each of the 9 tasks of the TEMPA-C execution speed dimension was negatively correlated with the score of the affected side of STEF, and the correlation coefficient ranged from -0.785 to -0.460. The total score of the TEMPA-C functional rating dimension was positively correlated with the scores of FMA-UE, FMA-UE wrist-hand part and the affected side of STEF, so was the total score of the TEMPA-C task analysis dimension, and the correlation coefficients were all above 0.7. Conclusion The TEMPA-C was highly reliable and valid, and could be used in measuring the function of upper extremity in patients with stroke.
