clonic

However, the clonic nature of the spasm should prevent such an error.

The musculature of thighs showed a more or less constant clonic twitching.

The clonic spasms may be so severe as to rupture muscles or even to fracture one of the long bones.

To this permanent tonic contraction of the muscles there are soon added clonic spasms.

It is a sort of half clonic, half tonic, tic of the foot, whose slowness is on a par with that of all her other acts.
