Ability to adjust reach extent in the hemiplegic arm
Physiotherapy, 2009Insufficient information exists about the ability of hemiparetic patients to adjust reach extent during early recovery from stroke. Further knowledge may suggest guidance for therapy intervention. The objective of this study was to investigate the ability of hemiparetic subjects to adjust reach extent within 6 months after stroke.Repeated-measures ...

Abstract This chapter examines the largest part of Coca-Cola’s massive greenhouse gas footprint in the twenty-first century: its refrigeration systems. Drawing on interviews with company officials inside the firm, it documents how Coca-Cola’s interest in rural markets slowed the firm’s transition from climate-changing hydrofluorocarbons (

Reaching a Point with an Unanchored Robot Arm in a Square
International Journal of Computational Geometry & Applications, 1997This paper considers an unanchored n-link robot arm in a square with side length at least as long as the longest arm link. The main result is a necessary and sufficient condition for a point in the square region to be reachable by a specified end of the arm. The condition takes O(n) time to determine.

Determining natural arm configuration along a reaching trajectory
Experimental Brain Research, 2004Owing to the flexibility and redundancy of neuromuscular and skeletal systems, humans can trace the same hand trajectory in space with various arm configurations. However, the joint trajectories of typical unrestrained movements tend to be consistent both within and across subjects.

Multijoint arm control: beyond reaching
Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (IEEE Cat. No.03CH37439), 2004We present a set of recent results on the control of movements in which the hand interacts with force fields that simulate the presence of dynamical objects and of surface boundaries. These experiments exploit the possibility of using human/robot interactions for exploring if and how the smoothness is enforced by the adaptive control system.

ARM and Rovsim: extending our reach
Industrial Robot: An International Journal, 1999This paper describes the development of the ARM System, an advanced subsea manipulator for weld inspection. ARM uses an advanced man‐machine interface and provides robotic control of the manipulator using techniques developed in factory robots. A more advanced robotic control system, Polecat, is currently being developed using experience gained from ...

Isodynes of women in the reaching area of the arms
International Journal of Production Research, 1973SUMMARY Some important factors of female work are analysed, and the importance and use of knowledge about maximum muscular strength of women in theory and praxis of Ergonomics, Biomechanics is demonstrated. With the term of maximum isometric muscular strength of position isodynes are defined as curves which join points of application of forces within ...

Head, arm and trunk coordination during reaching in children
Experimental Brain Research, 2008During postural and locomotor tasks, the orientation of the head with respect to space is maintained in order to serve as an egocentric reference value for maintaining balance. In young children during locomotor tasks, task difficulty determines the coordination of movements between head-trunk segments: the more difficult the task, the more the child ...

The leading joint hypothesis for spatial reaching arm motions
Experimental Brain Research, 2012The leading joint hypothesis (LJH), developed for planar arm reaching, proposes that the interaction torques experienced by the proximal joint are low compared to the corresponding muscle torques. The human central nervous system could potentially ignore these interaction torques at the proximal (leading) joint with little effect on the wrist ...
