Influence of Mechanical Terms in Quantifying Muscle Synergy during Cycling for FES Rehabilitation Applications

Sohrab Barimani; Ali Maleki; Ali Fallah

Volume 8, Issue 1 , March 2014, , Pages 101-111

  FES based method used for rehabilitation of patients with spinal cord injury (SCI). One of these methods is FES cycling. FES cycling exercise has to be useful among SCI patients because of creating a periodic activity in the muscles of the lower extremities and stability of seating position. The major ...  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

Comparison of Function Features using Modified DTW for Dynamic Signature Verification

Saeed Rashidi; Ali Fallah; Farzad Towhidkhah

Volume 4, Issue 2 , June 2010, , Pages 135-148

  Many methods are introduced for estimating the similarities or differences of time signals. One of theses methods, DTW algorithm, is also a utility for other domains including classification, data mining and matching regions between two time signals. DTW algorithm minimizes points distance between two ...  Read More

Authentication Based on Modeling of the Signature Velocity

Saeed Rashidi; Ali Fallah; Farzad Towhidkhah

Volume 4, Issue 3 , June 2010, , Pages 219-230

  Nowadays, fast and accurate algorithms for signature verification are very attractive. In the area of dynamic signature verification, the features are classified into two groups: parametric and functional features. In parametric algorithms, although the speed of features extraction and classification ...  Read More

Using Synergy to Control the Reaching Movement Neuroprosthesis: Muscle Synergy or Kinematic Synergy

Ali Maleki; Ali Fallah

Volume 2, Issue 2 , June 2008, , Pages 131-140

  Patients with spinal cord injury in C5/C6 levels are capable of controlling the voluntary movements of the shoulder joints, but some muscles involved in the movement of the elbow joint are paralyzed in these patients. By using FES as well as an appropriate stimulation of the paralyzed muscles, the patients ...  Read More

Biomechanical Motor Control / Motor Control of Human Movement
Signature Verification Based On The Control Theory Of Skilled Movements

Saeed Rashidi; Ali Fallah; Farzad Towhidkhah

Volume 1, Issue 4 , June 2007, , Pages 269-280

  Dynamic signature verification based on temporal features are more precise than the static methods because in addition to position information of the drawing pattern, it uses local and global features extracted from velocity, acceleration, pressure and pen angle signals, while static methods only use ...  Read More

Effect Of Continuous, Repeated And Intermittent Pressure On The Biomechanical And Histological Characteristics Of Guinea Pig Skin

Giti Torkamaan; Ali Fallah; Mahmoud Mofid; Sedighe Ghiasi; Ghadam Ali Talebi

Volume 1, Issue 3 , June 2007, , Pages 215-225

  In this study 22 male Guinea Pigs, 4-6 months old, weighting 400-450 g were used. A computer controlled indentor system was used to apply a controlled pressure. The applied pressure was 291 mmHg for 3 hours over the trochanter region of animal hind limb. The animals were divided in three groups; in group ...  Read More

Neuro-Muscular Engineering
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

Tissue Engineering
Skin Response To Applied Pressure In Model Of Guinea Pig

Giti Torkamaan; Ali Akbar Sharafi; Ali Fallah; Hamid Reza Katouzian; Mahmoud Mofid

Volume -1, Issue 1 , June 2004, , Pages 93-100

  Pressure ulcers are areas of tissue necrosis that tend to develop when tissue is compressed between a bony prominence and an external surface. Normal structure and physiological function of tissue viability are recognized but mechanism of tissue breakdown is unknown. In this study, an attempt has been ...  Read More
