Interrater Reliability ofthe Modified Tardieu Scale in the Assessment ofMuscle Spasticity in Stroke Patients

Objective: Spasticity is one component of the upper motor neu ron e syndrome, whic h is characterised by a veloci ty dependent increase in the tonic stretch reflexes . This study aimed at investigati ng the interrater reliability of the Modified Tardieu Scale in the assessment of muscle spas tici ty in stroke pat ients. Materials & Methods: In this analyt ical and va lidi ty testing study 30 patie nts with spastic hemipleg ia were se lected by simple sampling from clients of centra l ner vou s sy stem disorders cli nic of Tehran University of medical sciences . The two muscl e groups in affec ted upper limb were te sted usin g a s tandardized procedure. T hese were elbow f1exors and e xte nsors. Assessment was done by the two occupational therapists during the same session. The order of assessment and the sequence of muscle tes ting by the two raters were ra ndo m. The interr ater rel iability was calculated for the different subsales of Modified Tard ieu. The reliab ility was tested with the intraclass correlation coefficient (ICC) . For the Modified Tar die u Sca le scores, the Co hen ʹs Kappa test was used to analy ze the level of agree me nt between the raters. Results: The val ues of ICC fo r both muscle gro ups wer e high . The ICC for R2-R1 as main outcome measure for determinat ion of spasticity severi ty was 0 .99 and 0 .95 in the t1exors and exten sor s, respec tively. The Kappa va lues in mu scles reac tio n qn al ity were 0 .88 in fl exors and 0.89 in Extensors. Co nclusio n : The Mo d if ied Tardi e u Scale pro vides high in terr ater reli ab ilit y in the as sessment of muscle spa stici ty after stroke .
