Therefore, the specific aims of this study were (a) to measure in vivo maximum thumb circumductions
performed by a group of anthropometrically diverse participants and (b), through biomechanical modeling and statistical analysis, to establish a normative database of thumb circumduction
ROM and related kinematic characteristics while examining the effects of anthropometry, gender, and circumduction

For instance, an individual after stroke may successfully clear an obstacle in a timely manner and yet do so, primarily utilizing compensatory approaches like heavily relying on an assistive device or using inefficient movement strategies such as excessive hip hiking and circumduction
of the affected leg.
The iLimb, iLimb Pulse, Bebionic, and Bebionic v2 thumbs have actuated distal joints (i.e., MCP and PIP), while the circumduction
joint can be positioned in multiple states manually (the Vincent hand tested did not include a thumb).
Down strokes involve extension, pronation, and abduction (circumduction
) of the manus; extension and rotation of the forearm; and extension and rotation of the arm.
Deviations during the swing phase include a decreased foot-floor clearance, abnormal foot-floor contact after swing with the foot flat on the floor, and circumduction
of the hip with the knee in extension resulting in the dragging of the toes (2, 3, 8, 9, 10).
In practical terms, a muscle's intended biomechanical function (e.g., flexion, extension, adduction, abduction, elevation, depression, rotation, circumduction
, etc.) is heightened when combined with multiple synergists (assistant muscles) to perform a specific skill.
For instance, Smutz, Serina, and Rempel (1994) employed the goniometer for wrist posture measurement in their ergonomic assessment of keyboard designs; Moore, Wells, and Ranney (1991) and Wells, Moore, Potvin, and Norman (1994) used the goniometer to quantify wrist motion and posture in their field assessments of ergonomic risk factors; and Ojima, Miyake, Kumashiro, Togami, and Suzuki (1991) performed a dynamic analysis of wrist circumduction
using the goniometer in clinical trials.
of ankle joint will be done in supine or high sitting positioning in clockwise and anticlockwise directions, 20 repetitions are given in 1min.
For example, for elbow flexion, the rating of 1 corresponds to approximately -2.0 logits, while for wrist circumduction
the rating of 1 corresponds to approximately 1.0 logits.
