Median nerve compression is a well-known cause of carpal tunnel syndrome (CTS). Yet, reasons why the most common idiopathic form of CTS develops in certain individuals are not well understood. To further understand the compressive mechanisms at work in CTS development, the authors used ultrasonographic imaging of the median nerve to evaluate 2 patients with CTS. Findings were compared to those ...

The occurrence of prehensile tails among only five platyrrhine genera--Cebus, Alouatta, Lagothrix, Ateles, and Brachyteles--might be interpreted as evidence that these are a closely related, possibly monophyletic group. In the absence of behavioral data, it is impossible to test whether all possess equivalent biological roles; such would lend credence to the idea that their tails evolved from a...

The trapeziometacarpal joint enables the prehensile function of the thumb. Unfortunately, this joint is vulnerable to osteoarthritis (OA) that typically affects the local shape of the trapezium. A novel, local statistical shape model is defined that employs a differentiable locality measure based on the weighted variance of point coordinates per mode. The simplicity of the function and the smoo...

Prehensile robotic grasping of a target object in clutter is challenging because, such conditions, the touches other objects, resulting to lack collision free grasp affordances. To address this problem, we propose modular reinforcement learning method which uses continuous actions totally singulate from its surrounding clutter. A high level policy selects between pushing primitives, are learned...

one of the basic motor skills in childhood is manipulation skills. gross motor manipulation is a person's relationship with the objects and has this feature: force is applied to an object or the force of an object is absorbed. the aim of this study was to examine the effect of a selected motor program including team traditional games as motor experiences on manipulation skills development ...

background: esophagectomy is considered to be the main treatment for esophageal malignancies. among the different methods, transhiatal approach can cause less damage to patients and is widely used however, manipulation of esophagus result in heart rate and blood pressure variations. the aim of this study was to investigate changes in blood pressure and heart rhythm during transhiatal esophagect...

In this volume, an article by Hruby and Hoffman titled "Avian influenza: an osteopathic component to treatment" proposes the use of osteopathic manipulative treatment (OMT) as an adjunct to other forms of therapy in the management of a potential pandemic of avian influenza or "bird flu" [1]. This article is certainly timely and presents a much-needed reminder of the potential use of OMT in the ...

This study investigated the effects of a specific regimen of resistance training on coordinated actions of human hand digits during grasping. Participants were instructed to hold a rectangular object with all five digits and to maintain the orientation of the object against transient perturbation. Indices of co-varied actions (i.e., synergies) among multi-digit grasping and rotational actions w...
