Abstract:
Objective To study the correlation between isokinetic parameters and modified Ashworth Scale (MAS) in ankle spasticity as-sessment. Methods 18 stroke patients (spasticity group) and 16 healthy subjects (control group) in our hospitals from August 2014 to March 2015 were included. MAS was used to assess the ankle muscular tension. The ankle passive movement of both groups was measured with BIODEX isokinetic motor assessment system under 10 °/s, 60 °/s, 120 °/s, 180 °/s, 240 °/s. The peak torque (PT), peak torque/body weight (PT/BW), average torque (AT), and slopes of the linear regression curve of torque-velocity (SLOPE) were recorded. The correlation of the isokinetic paramenters and the MAS were tested with Spearman correlation analysis. Results The PT, PT/BW and AT were higher in the spasticity group than in the control group (P<0.05). And they increased as the angular velocity increased, and slowed after 120 °/s. The corre-lation coefficient of MAS and PT, PT/BW, AT, SLOPE were from 0.3043 to 0.7632 (P<0.01). Conclusion The isokinetic parameters were speed-dependent and closely related to MAS. 120 °/s was of the highest sensitivity, and the SLOPE under this anglular velocity was highly correlated with MAS.
