Abstract

The reliability of the Modified Tardieu Scale (MTS) has not been examined in patients with multiple sclerosis (MS). This study aimed to assess intra-rater reliability of the MTS in the assessment of lower limb spasticity in patients with MS. Data from 30 patients with MS (18 women, mean age = 41.5) were used to assess intra-rater reliability. An inexperienced physiotherapist in the scale randomly examined the hip adductors, knee extensors, and ankle plantar flexors on each subject twice with at least a 7-day interval. Kappa statistics (κ) were calculated for MTS quality of muscle reactions. Intraclass correlation coefficients (ICCagreement) and smallest detectable change (SDC) were calculated for R2, R1, and R2–R1. Qualitative rating of spasticity demonstrated moderate or good agreement, with an overall moderate κ of 0.72. Intra-rater reliability for all angle components of MTS was poor to good (ICCagreement range 0.45–0.83). The SDC for all the MTS components across the muscle groups was unacceptably large (range 14.6–55.6). Results did not establish good intra-rater reliability for the MTS when assessing lower limb muscle spasticity in patients with MS by a physiotherapist with no previous experience in the scale and with limited training. © 2016, Springer-Verlag Italia.
