Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured.
The following types of contributions and areas are considered:
1. Original articles:
Technology development in medicine: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine.
Significance of medical technology and informatics for healthcare: The appropriateness, efficacy and usefulness deriving from the application of engineering methods, devices and informatics in medicine and with respect to public health are discussed.
2. Technical notes:
Short communications on novel technical developments with relevance for clinical medicine.
3. Reviews and tutorials (upon invitation only):
Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented.
4. Minisymposia (upon invitation only):
Under the leadership of a Special Editor, controversial issues relating to healthcare are highlighted and discussed by various authors.
Abstract: The historical development of electrical stimulators producing contraction of paralyzed muscles is briefly presented. The influence of electrical stimulation parameters (amplitude of pulses, frequency, pulse duration, and duration of a pulse train) is explained. Special attention is paid to the description of the muscle recruitment curve. The phenomenon of reversed recruitment order, resulting in fatiguing of electrically stimulated muscle, is presented. The properties of surface electrodes (electrode size, polarity, resistance, and distance between electrodes) are examined. The use of surface electrodes made of metal plate or wire mesh, silicone impregnated with rubber, and conductive adhesive gel are discussed. The design…of electrical stimulator circuits is also presented.
Abstract: The part of (bio)mechanics that studies the interaction of forces on the human skeletal system and its effect on the resulting movement is called rigid body dynamics. Some basic concepts are presented: A mathematical formulation to describe human movement and how this relates on the mechanical loads acting on the skeletal system. These equations of motion depend on the mechanical properties of the skeletal system, such as dimensions and mass distribution. It is applied to describe and analyze human gait.
Keywords: Human movement, rigid body dynamics, gait analysis
