Trial Outcomes & Findings for Effects of Hamstring Training in Different Modes on Stabilizing Knee Joints With Anterior Drawer Laxity (NCT NCT01170546)

Results Overview

The KT-2000 knee ligament arthrometer (MED Metric Co., San Diego, USA) is designed to assess the anterior drawer laxity of the knee joint. The discrepancy of anterior displacement between the sound side and the lesion side is applied in evaluating the static stability of the knee.

Participant Flow

Knee joint laxity was surveyed by a KT-2000 test during 2006, Feb and 2006, March. The anterior drawer laxity of the knee joint was defined as anterior displacement over 3 mm discrepancy between bilateral knee joints by a KT-2000 test under 20-pound force.

One hundred and seventy-three students were tested and 30 met the criterion, including 22 males and 8 females. Two males were excluded due to other causes that might affect muscle strength or knee stability such as lower limbs fracture and arthritis. Besides, eight female students were eliminated to avoid possible gender difference.
