[Direct biophysical effects of ultrasonic stimulation on the living rabbit lower limb].

Ultrasonic applications of low up to high intensity during 2 minutes led to biophysically provable changes (behaviour of bioimpedance, pO2, and temperature) in vital tissues (musculature, periosteum, and bone marrow). The most effective application was noticed by static ultrasonic therapy of 0.2 W/cm2. Repeated ultrasonic therapies of low intensity effected involved, for instance, an adaptation of the temperature and an increase of the electrophysical stimulation (bioimpedance).
