Answer: 2
Sprain is characterized by increased pain with joint motion. Sprain involves a ligament injury. Because of this, sprains can cause instability of the joints. Strain is caused by a stretching injury to a muscle. It is manifested by increased pain with isometric contraction of the affected muscle.
Sprain: 捻挫 Strain: 肉離れ という訳るのでしょうか。歪み計をストレインゲージというから歪みかと思っていたら、strainは"張る"という意味で使われるみたいです。
