circumduction

/cir·cum·duc·tion/ (-duk´shun) circular movement of a limb or of the eye.

circumduction

(sûr′kəm-dŭk′shən)
n.
The circular movement of a limb such that the distal end of the limb delineates an arc.

circumduction

[sur′kəmduk′shən]
Etymology: L, circum + ducere, to lead
1 one of the four basic movements allowed by the various joints of the skeleton. It is a combination of abduction, adduction, extension, and flexion. An example is the motion of a bone whose head articulates with a cavity, such as the femur with the acetabulum. The motion of the bone circumscribes a cone, the apex of which is in the cavity and the base of which is described by the distal end of the bone.
2 the circular movement of a limb or of the eye. Compare angular movement, gliding, rotation.

1] joint dominated thumb circumduction and the participants were instructed to inhibit the movement of the MC[P.
We performed regression analyses to examine the effects of anthropometry, gender, and circumduction direction on the following four groups of 18 dependent measures: Group 1, the CM[C.

Statistical summaries of the 18 measures derived to describe the thumb circumduction kinematics and ROM, presented in Tables 2 and 3, where they are stratified by gender and by direction of circumduction, respectively.

Noteworthy also are some characteristic patterns or trends exhibited by the thumb circumduction and a few measures.
There have also been attempts to investigate thumb circumduction ROM through the use of cadaver specimens (Imaeda et al.
Further, the modeling approach did not mask the fact that the three joints of the thumb do not naturally remain completely rigid during a conical rotation or circumduction (Kapandji, 1981), despite the participants' attempt to stiffen the I[P.
All subjects compensated for the loss of knee flexion during swing phase through hip hiking (increased pelvic obliquity), and three subjects additionally used circumduction (increased orthotic-side coronal plane thigh angle during swing phase) to create adequate swing-phase toe clearance.
In this study, we hypothesized that the auto-mode oxygen cost would be significantly lower than the locked mode, but despite significant reduction in compensatory mechanisms such as hip hiking and circumduction, no significant difference was noted between auto- and locked-mode oxygen cost.
