The lower limb exoskeleton can help the paralyzed walk again, also can be used to reduce the body weight. it is necessary to promote the anthropomorphic and man-machine matching of exoskeleton. The man-machine matching is divided into two, one is the structure matching and the other is the driven matching involving the biomechanics of the muscle. This article puts forward the design rule of exoskeleton...
This paper presents some theoretical and experimental considerations about shoe heel effect on comfort and bipodal balance. These influences are determined by evaluating the thermal gradient, in parallel with plantar pressure at the surface of human subjects flange wearing high heels (about 10 cm). Also, in the third part of the paper, the correlation of plantar pressures to the shape and structure...
This paper describes design and test of a wearable FES system for the purpose of improving the performance of gait in patients with post-stroke. The prototype system that was developed includes electrical stimulator and sensor systems. Electrical stimulator was designed to generate pulse train that was realized using non-isolated boost converter. Sensor system was designed to measure gait phases that...
The purpose of this study was to investigate the effects of treadmill training (TT) with functional electrical stimulation (FES) applied on the gluteus médius (GM) and tibialis anterior (TA) muscles on gait and balance performance in individuals with hemiparetic stroke. Thirty-six participants who had chronic hemiparetic stroke, were recruited in this study, and were randomly distributed into three...
Ankle-foot orthoses (AFOs) can be used to ameliorate the impact of impairments to the lower limb neuromuscular motor system that affect gait. Existing AFO technologies include passive devices with fixed and articulated joints, semiactive devices that modulate damping at the joint, and active devices that make use of a variety of technologies to produce power to move the foot. Emerging technologies...
Functional electrical stimulation (FES) is used to correct the foot-drop. A portable single channel low cost electrical stimulator has been developed with a very flexible architecture to optimize functionality while keeping its size and power consumption to a minimum. A microcontroller core is utilized to enable the implementation of different controls of the stimulator. The reported benefits shown...
