Fig 2. The occurrence frequencies of spastic behaviors and corresponding amplitudes of muscle activity during the test period.

Fig 2

(A) The occurrence frequency and percentage of each type of spasticity (clonus, black bars; spastic, grey bars; total, white bars) observed in the spasticity-strong group during the swimming tests from 4 to 6 weeks after SCI. (B) The mean amplitude of muscle activity of spastic behaviors in the spasticity-strong group during the swimming test from 4 to 6 weeks after SCI recorded from the left TA muscle (blue) and the left MG muscle (orange). Mean amplitudes of muscle activity at 4 weeks were considered to be 100%. Abbreviations: TA, tibialis anterior; MG, medial gastrocnemius; n.s, not significant.
