چکیده

Manipulation depends on the thumb's ability to produce well-directed forces of sufficient magnitude. We currently lack a model of the thumb that can realistically predict thumbtip forces in 3D, and the coordination patterns that produce them (Valero-Cuevas, et al., 2003). This may be because the assumed model structure is not able to reproduce functional outputs, and/or because the search for adequate model parameter values has been unsuccessful. Understanding the inherent biomechanical abilities of a chosen model structure is a necessary first step to modeling the thumb for clinical use and studies of neural control of the hand.

Anatomical Variability Naturally Leads to Multimodal Distributions of Denavit - Hartenberg Parameters for the Human Thumb

—A realistic biomechanical model of the thumb would enhance our understanding of the functional consequences of orthopedic and neurological diseases, and of treatments. Our work has shown that a kinematic description with five orthogonal and intersecting axes of rotation cannot predict realistic thumbtip forces. An alternative kinematic description proposes five axes of rotation that need not b...

Towards a realistic biomechanical model of the thumb: the choice of kinematic description may be more critical than the solution method or the variability/uncertainty of musculoskeletal parameters.

A biomechanical model of the thumb can help researchers and clinicians understand the clinical problem of how anatomical variability contributes to the variability of outcomes of surgeries to restore thumb function. We lack a realistic biomechanical model of the thumb because of the variability/uncertainty of musculoskeletal parameters, the multiple proposed kinematic descriptions and methods t...

Objective Alteration of scapular position and motion is called scapular dyskinesis. Scapular dyskinesis is a common clinical problem. Strength of shoulder girdle muscles is important in shoulder motions and stability, so their weakness may lead to scapular dyskinesis. The aim of this study was to compare the maximum voluntary isometric force of shoulder girdle movements in subjects with and wit...

A closed-form solution for the flat-state geometry of cylindrical surface intersections bounded on all sides by orthogonal planes

Presented herein is a closed-form mathematical solution for the construction of an orthogonal cross section of intersecting cylinder surface geometry created from a single planar section. The geometry in its 3-dimensional state consists of the intersection of two cylindrical surfaces of equal radii which is bounded on all four sides by planes orthogonal to the primary cylinder axis. A multivari...

In vivo kinematics of the first carpometacarpal joint after trapezectomy.

UNLABELLED First carpometacarpal osteoarthitis is frequent and surgery may be necessary if medical treatment is not efficient. Trapeziometacarpal arthroplasty, trapeziometacarpal arthrodesis and trapezectomy may be proposed. These surgical solutions may modify the carpometacarpal kinematics of the thumb. However, no clinical tools are currently available to assess these modifications. The goal ...
