[The affect of the skin stretch on the biomechanical changes of skin].

Objective: To investigate the biomechanical changes in skin after employing the skin stretch.

Methods: Skin samples were took from the test group which was stretched for 7 days and control group without stretch respectively in the end of 1, 2, 3, 4, 6, 8 week. The biomechanical index were measured by tensiometer.
