introduction: nowadays the use of music therapy for neurological disorders in developed countries is widely emphasized. despite this, there is little scientific evidence regarding the use of this method for the treatment of iranian patients with stroke. case report: since iranian patients are more familiar with persian music,this study was performed to describe the effects of listening to the p...

Abstract Aims Laparoscopic surgery is technically challenging and assessment of competency necessary to ensure patient safety guide training. Existing tools are mostly subjective, with a growing need for objective credentialing. LapPass™ was developed by UK-based laparoscopic society as an accessible simulation tool. The aim this study report on its development preliminary findings usability va...

It is well documented that interval (INT) and continuous (CONT) exercise result in different patterns of blood flow and heat exchange in both heat 8 and cold. 9 Exercise can improve finger temperature 10, 11 and manual dexterity 12, 13 in the cold, but the type of exercise (interval vs. continuous cycling, matched for energy expenditure) has never been evaluated under this paradigm. Thus, we so...

Abstract In this paper a dexterity measure is proposed for driftless nonholonomic systems. Admissible motions at a given state of a nonholonomic system are described by the controllability (Lie) algebra of the system. The algebra is completely described by Lie monomials (vector fields) produced by the Lie bracketing of vector fields associated with the system. At a given state, the nonholonomic...

The All-Terrain Biped (ATB) robot is an unmanned ground vehicle with arms, legs and wheels designed to drive, crawl, walk and manipulate objects for inspection and explosive ordnance disposal tasks. This paper summarizes on-going development of the ATB platform. Control technology for semi-autonomous legged mobility and dual-arm dexterity is described as well as preliminary simulation and hardw...

This paper studies and formulates the workspace of laparoscopic extenders(e.g. graspers, needle drivers, scissors etc.)with exible stems, that provide additional DOF, and dexterity at the surgical sight. Optimization techniques are used to synthesis the designs of exible stems. The dexterous workspace is determined for 3 di erent types of designs. By de ning a new dexterity measure the number o...

We have developed a method to quantify the dynamic interaction between fingertip force magnitude (strength) and directional control (dexterity) during pinch with a novel strength-dexterity (S-D) test based on the principle of buckling of compression springs. The test consists of asking participants to use key and opposition pinch to attempt to fully compress springs, in random order, with a wid...

The primary purpose of the present study was to compare the effectiveness of two forms of hand heating and to discuss specific trends that relate finger dexterity performance to variables such as finger skin temperature (T(fing)), finger blood flow (Q(fing)), forearm skin temperature (T(fsk)), forearm muscle temperature (Tfmus), mean weighted body skin temperature (Tsk), and change in body heat...
