Abstract
OBJECTIVES: The purpose of this study was to investigate Iintra-rater reliability of the Modified Tardieu Scale (MTS) in elbow flexors and ankle plantar flexors in adult subjects with stroke. MATERIALS AND METHODS: A total of 91 subjects with stroke participated in this test-retest study. Intra-rater reliability of the MTS was investigated by a qualified and trained physiotherapist for elbow flexors and ankle plantar flexors in two sessions. A rater was one who performed the procedure and an observer only records the angles so that the rater was blinded to findings. Outcome measures in this study were measurable components of MTS, which are angle of muscle reaction (R1), passive range of motion (R2), dynamic component (R2-R1), and quality of muscle reaction (grade 0 - 4) termed as MTS score. RESULTS: Intra-rater reliability of MTS was very good for R1, R2, R2-R1, and MTS score (ICC > 0.85, P<0.0001) across two sessions in elbow flexors and ankle plantar flexors. CONCLUSION: MTS is a reliable clinical tool for measurement of spasticity in the elbow flexors and ankle plantar flexors in adult subjects with stroke.
