We studied the frequency of the contracture of the quadriceps and the hamstrings muscles in 822 healthy male. The angle of the buttock elevation phenomen (BEP) and the straight leg raising test (SLR) were utilized for detection of above conditions.
The contracture of the quadriceps which BEP showed below 100 degrees was found in 16.1%. The mean value of the angle of BEP was 124.0±16.71 on the right leg and 122.2±19.75 on the left.
The contracture of the hamstrings which SLR test showed below 70 degrees was found in 31.3% with mean value of 79.3±9.56 on the right and 79.9±9.84 on the left.
