Is Electrical Stimulation Beneficial for Improving the Paralytic Effect of Botulinum Toxin Type A in Children with Spastic Diplegic Cerebral Palsy?. 1983; Frank et al. Conversely, reducing the duration of a pulse improves the range resolution of the radar. The theoretically calculated pulse durations are found to be in a good agreement with the respective experimental data from frequency-resolved optical gating … In addition, the frequency and pulse duration used during protocol 2 were similar to the 3. Since ATP utilization by actin–myosin ATPase is proportional to force generation (Boska, 1994; Potma et al.
