Do Three Different Passive Assessments of Quadriceps Spasticity Relate to the Functional Activity of Walking for Children Diagnosed with Cerebral Palsy?
Table 2
Dependent and independent measures (, , , values between stiff- and not-stiff-knee groups; statistical comparison includes all grades of Modified Ashworth Scores between stiff-knee and not-stiff-knee groups).
