Objective: In our study, the measurement of joint motion capacity of knee and ankle at adults not having any medical problem was aimed.

Materials and Methods: Measurements were carried out on the subjects whose ages change between 17-22 in 40 men and 40 women by using digital electronic inclinometer. Flexion, int. Rotation, ext. Rotation motion capacities at knee joint were measured at right-left side for men and women.

Results: At flexion volume for men and women among each other and in right-left isn't statistically significant (p>0.05). However, when men compared with women: int. rot for men is 11±1.9,ext. rot is 24±2, for women; int. rot. is 9.6±1.8, ext. rot. is 20.8±2.3, rotation (internal-external) range of motions was seen more significant statistically in favor of men (p<0.05). Range of motions of dorsal flexion, plantar flexion, inversion and eversion at ankle joint were measured. Difference significant statistically was not found when ankle movements of men and women were compared between each other. While significant difference in favor of men was found at dorsal flexion motion capacity (21.2±2.3 for men, 19.1±2.2 for women) (p<0.05 ), difference among motion capacities of plantar flexion, inversion and eversion was not detected (p>0.05).

Conclusion: We have thought lower level of motion capacities of rotation at knee and dorsal flexion at ankle compared to men can be associated with wearing high-heeled shoes. Because, joint kinetics of knee and ankle degenerate at the women wearing high-heeled shoes. Finally, we think that average motion capacity values we have found will form a standard for healthy and young Turkish people and be a guide for physicians with respect to treatment of motion losses occurred at joint diseases.
