The following playlist contains manual muscle tests to assess specific muscle strengths and are to be used as part of a physical examination. Note: Body mechanics in these videos may be slightly Step 1 Place muscle in shortened position,or to point of joint compensation. Ask client to hold that positionwhile applying pressure. Gradually increase pressure. Clients strength is graded If client can hold the position without compensation, then the muscle is noted as strong. If the muscle is weak or compensates, move to step 2. Survivors of acute respiratory distress syndrome (ARDS) and other causes of critical illness often have generalized weakness, reduced exercise tolerance, and persistent nerve and muscle impairments after hospital discharge. 1-6 Using an explicit protocol with a structured approach to training and quality assurance of research staff, manual muscle testing (MMT) is a highly reliable method for Research on Training of Skeletal Muscles. Skeletal muscle is the most abun
