2. Fig. 1
EMG and knee extensor force responses following a patellar tendon tap in a population of patients with spastic CP and in normally developing subjects. Response curves represent the mean of each population from both knee angles. The patellar tendon tap is at time t = 0. EMG data were normalized to isometric MVC levels.

3. Fig. 2
Reflex EMG in the quadriceps and antagonistic EMG response in the hamstrings were significantly greater in the patients with spastic CP than in the normal subjects. Peak reflex force responses were not statistically influenced by subject group.

5. Fig. 4
Muscle force response as modeled in the appendix, representing the time-dependent behavior without antagonism, and the behavior including antagonistic contraction at a level of ρ =.25. EMD with antagonistic activity, EMD, is longer than without, EMD0.
