1. The total range of motion, in flexion and extension, at the hip joint in normal young adult males is approximately 146 degrees on both sides, the average flexion being 114 degrees and the average extension 32 degrees.[SEE FIG.6 AND FIG.7 IN SOURCE PDF.]

2. The range of motion in the individual lies between 121 degrees and 175 degrees.

3. Deviations from the average range are slightly more marked in extension.

4. The flexion: extension ratio decreases as the total range increases.

5. The range of motion shows no relation to height or weight except when the extremes are reached.

6. No marked tendency to right- or left- "leggedness" is demonstrable from the range of motion that exists.
