RECOVERY FROM IMMOBILIZATION-INDUCED ATROPHY OF RABBIT SOLEUS MUSCLES CAN BE ACCELERATED BY CHRONIC LOW-FREQUENCY STIMULATION
1 Department of Physiology, Marischal College, University of Aberdeen, Aberdeen AB9 1AS
Immobilization of rabbit soleus muscles with an ankle joint angle of 90° led to gross degeneration after 2 weeks. Natural recovery in the subsequent 2 weeks had little effect on the mean area of soleus fibres, although there were signs of regeneration. However chronic low-frequency activation of soleus muscles by nerve stimulation greatly accelerated recovery, producing muscle fibres of normal areas and with characteristics of maturity.
