영문 초록

  The purpose of this study was to determine the effectiveness of a modified sitting position straight leg raise on Vastus Medial Oblique(VMO) strength and EMG activity as compared to a traditional leg raise.
  A total of twenty-three subjects were recruited for this study. The subjects were randomly assigned to one of the following groups: (group Ⅰ) Modified Straight Leg Raise(MSLR), and (group Ⅱ) Straigh Leg Raise (SLR). The exercise program was three weeks long. University procedured for the protection of human subjects were followed. The subjects began with a 5 minutes warm-up on a Cybex stationary bike set at 90 revolutions/minute. The subject then had electrodes placed on the Vastus Lateralis(VL) and Vastus Medialis Oblique(VMO). A Mackintosh computer was use to record the EMG data. The subject then perform a standard Cybex test for knee flexion and extension. The Cybex dynamometer was placed at the knee joint line, the chair back tilt was at 85 degrees, the hip, chest, and thigh restrains were all fastened. The subjects in Group Ⅰ(Modified sitting SLR) and Ⅱ(SLR) then returned the next day for their first rehabilitation lesson. Each subject group then participated in their respected exercise program for a total of three weeks. After three weeks of rehabilitation, the subjects retested using the same procedures followed in the pretest. A two tailed t-test was used to determine significance of the difference between means of the two groups. No significant differences were found between the two groups.
