II
Mild pain more than 48 hours after activity, no pain during activity, can be relieved with warm-up exercises, and recovers within 72 hours
III
Mild pain before and during activity, no significant negative impact on the activities, and can be partially relieved with warm-up exercises
IV
Mild pain accompanies the activities of daily living and has negative impact on the performance of activities
V
Harmful pain unrelated to activities, great negative impact on the performance of activities but does not prevent the activities of daily life. Need complete rest to control the pain
