a pt sustained an injury 3 days ago & the PTA is providing the pt w education regarding applying cryotherapy at home. which of the following statements would be MOST appropriate for the PTA to include?
Wait at least 2 hours between cryotherapy applications
Apply ice whenever your pain levels rise
Apply ice for at least 30 minutes to get the maximum benefits
When icing at home, it is not important to visually inspect the treatment area
wait at least 2 hours between cryotherapy applications
A PTA has completed sensory testing w a pt that suffered cerebrovascular accident (CVA) 6 months ago. The PTA is applying the 1st NMES treatment for muscle re-education of the wrist extensors. which of the following parameters is most appropriate for this treatment
