Abstract

In humans the sural nerve was stimulated at one of 16 phases of the step cycle. In MG (medial gastrocnemius) the amplitude of the P2 responses (latency 80-93 ms) was on average 1.3 times larger than the corresponding background activity while this was 0.9 for LG (lateral gastrocnemius; predominantly suppressive responses). It is speculated that such differences contribute to an exorotation moment during gait.
