Black box modeling of Paralyzed Arm for FES-based Reaching Movement Control in SCIPatients

Rahele Shafaei; Seyed Mohammad Reza Hashemi Golpayegani

Volume 5, Issue 3 , June 2011, , Pages 214-228

  One of main the issues in achieving to a successful FES control is using an as much as possible accurate model of the under electrical stimulation system so that it can adequately indicate the system behavior. Classical computational models that are commonly used for this purpose have a reductionism ...  Read More

Power Law: Relation Between Geometry And Kinematics In Skilled Drawing Movements

Saeed Rashidi; Seyed Mohammad Reza Hashemi Golpayegani; Ali Fallah; Farzad Towhidkhah

Volume 4, Issue 1 , June 2010, , Pages 33-44

  In drawing movements, the constraints imposed on the trajectory geometry properties and kinematics are known with two laws: 2/3 power law and isochrony phenomenon. In this paper experiments have been designed to study the relation between two empirical laws in straight and curved patterns of drawing ...  Read More

The Cybernetical Model Of Pain And State-Dependent Sensory Processing In The Dorsal Horn Of The Spinal Cord

Siamak Haghipour; Seyed Mohammad Reza Hashemi Golpayegani; Seyed Mohammad Firouzabadi; Sirous Momenzadeh

Volume 3, Issue 3 , June 2009, , Pages 227-241

  The procedure of pain formation embarks on primary sensory neurons and then ends in central nervous system which is the first stage in the dorsal horn of the spinal cord. Nowadays the great challenge of some researchers for pain control has been to elucidate the mechanisms that are able to switch the ...  Read More

A Model For Skill Movements Based On Self-Organized Control Strategy

Amir Homayoun Jafari; Seyed Mohammad Reza Hashemi Golpayegani; Farzad Towhidkhah; Ali Fallah

Volume -2, Issue 1 , July 2005, , Pages 57-70

  A hierarchical structure model with three levels is presented for modeling motor control in skill movements. At each level, based on accuracy and quality of control, a specific controller is activated. At first level, control concepts are qualitative. The duty of the first level is to provide stability ...  Read More

Effects Of Depolarizing Prepulses With Different Parameters On The Selective Stimulation Of Myelinated Fibers And Suggestion Of A New Prepulse Waveform With Superior Performance Based On Simulation Of

Amin Mahnam; Seyed Mohammad Firouzabadi; Seyed Mohammad Reza Hashemi Golpayegani

Volume -1, Issue 1 , June 2004, , Pages 65-76

  In recent years, various methods have been suggested to improve selectivity in electrical stimulation of neural fibers or cells. One of these methods is the use of depolarizing under-threshold prepulse to selectively stimulate fibers far from the electrode, without excitation of nearer fibers. In this ...  Read More
