Abstract: Study investigated whether a custom-made, motor-controlled device could be used to safely measure extension stiffness in stroke survivors with mild-to-moderate spastic paresis of the upper limb. Furthermore, it examined whether the changes in the measured values could quantitatively reflect the spastic state of the flexor muscles involved in the wrist stiffness of the patients. Resistance forces were measured in 17 patients during repetitive passive extension of the wrist at velocities of 30, 60, and 90 degrees per second. The Modified Ashworth Scale (MAS) was also assessed in the wrist and finger flexors by two skilled therapists and the scores were averaged for analysis. For the analysis, fluctuation of resistance focused on the damping just after the peak forces. A repeated-measures analysis of variance was conducted to assess velocity-dependence. Correlations between MAS and damping parameters were analyzed using Spearman’s rank correlation. The damping force and normalized value calculated from damping part showed significant velocity-dependent increases. There were significant correlations between average MAS for wrist and the normalized value of the damping part at 90 degrees per second. The correlations became stronger at 60 and 90 degrees per second when the MAS for finger flexors was added to that for wrist flexors. This custom-made isokinetic device could quantitatively evaluate spastic changes in the wrist and finger flexors simultaneously by focusing on the damping part, which may reflect the decrease in resistance we perceive when manually assessing wrist spasticity using MAS.
