This study used data from the first National Health and Nutrition Examination Survey (NHANES 1), which involved a national probability sample of persons drawn from the civilian noninstitutionalized population of the United States. ~DERSSON Department of Orthopaedic Surgery I, Sahlgren Hospital, Goteborg, Sweden Studies of the normal range of joint motion in human adults are uncommon, and This is the range through which a joint can be moved, usually its range of flexion and extension, as determined by the type of joint, its articular surfaces, and that allowed by regional muscles, tendons, ligaments, joints and physiologic control of movement across the joint.Range of motion is the extent of movement of a joint, measured in degrees of a circle. As a general rule, a knee flexion of about 125° will allow you to carry out most normal activities. Van Dillen LR, McDonnell MK, Fleming DA, Sahrmann SA. You can see the wide variation, so the quoted ranges for men and women serve only as guidelines. Clipboard, Search History, and several other advanced features are temporarily unavailable. Goniometric measurements of hip and knee active range of motion (AROM) were obtained from a subset of the sample consisting of 1,892 subjects. Flexion – 120-150 degrees; Internal rotation with knee flexed – 10 degrees; External rotation with knee flexed – 30-40 degrees; The total range of motion is dependent on several parameters such as soft-tissue restraints, active insufficiency, and hamstring tightness. A … This is called hyper-extension, and a few degrees of hyper-extension is normal. The authors concluded that at some point, there may be a limit to the benefits gained by a higher range of motion after TKR. CDC collected range of motion (ROM) measurements of the elbow, shoulder, hip, knee and ankle from a sample of individuals without known medical or physical conditions affecting the joint mobility. 2019 Dec 25;66(3):271-280. doi: 10.5606/tftrd.2020.4317. Relationships have been reported between the range of joint motion in general and disability. Note how two of the individuals have such good extension that the knee can actually bend backwards a little bit, and the the heel lifts right up off the bed? These include physical factors such as a reduced range of motion (ROM) of the joints [2]. 2020 Jul 11;9(7):2194. doi: 10.3390/jcm9072194. 2019 Dec 12;7(1):77-84. doi: 10.1093/jhps/hnz062. Because the decision to treat impaired joint mobility in an older individual may be influenced by assumptions concerning normal range of motion (ROM) at older ages, it is important to establish population-based normative values for hip and knee ROM by age, race, and sex. 2000 Jun;30(6):307-16. doi: 10.2519/jospt.2000.30.6.307.

Age-related changes in the interactive mobility of the hip and knee joints: a geometrical analysis. HHS Range of motion (ROM) is the measurement of the amount of movement around a specific joint or body part. Goniometric measurements of hip and knee active range of motion (AROM) were obtained from a subset of the sample consisting of 1,892 subjects. Only in the case of hip extension did the difference in mean AROM between the youngest and the oldest age groups constitute a decline of more than 20% of the arc of motion. A joint is a location in the body where bones connect. J Clin Med. The dial is fixed to the one arm. For example, if the veteran lacks 10 degrees of full knee extension and has normal flexion, show the range of motion as extension to minus 10 degrees (or lacks 10 degrees of extension) and flexion 10 to 140 degrees. The standard motion range (AROM) of a knee is 0° extension and 140° flexion. An approximation to this vertical motion can be seen in the position of the hip joint in Figure 2.4.

Without the normal range of motion, the affected joint is still injured. It is a common misconception that 0-140 degrees is a normal range of motion, but most people have some hyperextension, too, taking their ROM into negative numbers. In practice, however, if you do not have a goniometer (and even if you do), a useful measure of the difference between both legs is the distance of each heel from the buttock. A patient was considered to have normal range of motion if extension was within 2° of the opposite knee including hyperextension and knee flexion was within 5°.
