  • Relationship between resistance components in spastic wrist flexors and clinical scales of stroke survivors

    Objective To explore the components of passive movement resistance in the wrist flexor in subjects after stroke, and investigate the correlations between these components and clinical scales such as Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment (FMA). Methods From March to August 2017, a cross-sectional study was performed in 15 stroke survivors in the Department of Rehabilitation Medicine, the First Affiliated Hospital, Sun Yat-sen University. MAS and FMA were assessed by an experienced physical therapist. Components of passive movement resistance in the flexors of wrist and finger were recorded by NeuroFlexor (Aggro MedTech AB, Solna, Sweden), then the average resisting force in one second ensued the passive stretch at 5°/s was took as peak resisting force (PRF). The PRF between paretic side and non-paretic side was compared. Spearman’s rank correlation was used to test the relation between the components and clinical scales. Results The PRF of the paretic side during the slow passive stretch (5°/s) was significantly higher than that of the non-paretic side [(10.49±1.65) vs. (8.98±1.11) N, P<0.05]. Correlations between MAS and the components/PRF were insignificant (P>0.05). FMA had a significant correlation with neural component of the paretic side (rs=–0.645, P=0.009). Conclusions The higher PRF of slow passive stretch in the paretic side may be attributed to the higher muscle stiffness. Neural component of the paretic wrist is correlated with FMA. These findings could be applied in clinical evaluation of functional performance of the wrist muscle of stroke survivors.
