Muscle strength is often rated on a scale of 0/5 to 5/5 as follows:

• 0/5: no contraction
• 1/5: muscle flicker, but no movement
• 2/5: movement possible, but not against gravity (test the joint in its horizontal plane)
• 3/5: movement possible against gravity, but not against resistance by the examiner
• 4/5: movement possible against some resistance by the examiner (sometimes this category is subdivided further into 4^–/5, 4/5, and 4⁺/5)
• 5/5: normal strength

Heart Murmers:

• Grade 1 – very faint
• Grade 2 – quiet but heard immediately
• Grade 3 – moderately loud
• Grade 4 – loud
• Grade 5 – heard with steth partly off chest
• Grade 6 – no steth needed

Deep Tendon Reflexes

• 0 : absent reflex
• 1+ : trace, or seen only with reinforcement
• 2+: normal
• 3+ : brisk
• 4+ : nonsustained clonus [repetitive vibratory movements]
• 5+ : sustained clonus
