AB  - The purpose of this study was to evaluate and compare the test-retest reliability 
      of isokinetic torque measurements in the involved and uninvolved knee musculature 
      of 20 subjects with spastic hemiparesis. An isokinetic dynamometer was used to 
      measure maximal voluntary knee extension and flexion at 60 degrees and 120 
      degrees/s. Peak torque (PT) and average peak torque (APT) data were collected 
      from five repetitions on two separate occasions. Average peak torque was defined 
      as the mean of the PT values obtained during each of the five repetitions. 
      Spasticity was measured in the involved knee musculature prior to isokinetic 
      testing using the Ashworth Scale. Pearson Product-Moment Correlation Coefficients 
      and intraclass correlation coefficients (ICCs) were high (greater than or equal 
      to .90) for both knees for PT and APT at both angular velocities. No clinically 
      meaningful differences were found between the Pearson correlation coefficients 
      and the ICCs of the involved versus the uninvolved knee for any testing 
      conditions. We concluded that isokinetic evaluation of torque, as measured by PT 
      and APT in subjects with spastic hemiparesis, can yield reliable results in both 
      extremities.
