[Effect of long-term cryotherapy on the Hoffmann reflex]

Investigations about Hoffmann reflex of M. triceps surae on both extremities were carried out on 10 young volunteers before and after cryoapplication of ten minutes on the left leg. Determination of H/M ratio indicates the influence of cold application on muscle tonus, which was decreased on the treated side without any influence on the contralateral. The results support the view that muscle relaxation depends on decrease of muscle temperature.
