For how long do we apply electrical stimulation?
15–120 sec
What is the function of electrical stimulation?
- ES enhances postmortem glycolysis
- ES prevents muscles form cold shortening during rigor mortis
- ES causes pronounced degradation of myfibrillar proteins
- ES causes significant tenderization
- ES affects tenderness by stimulating calpain activity
