A large amount of hemiplegic survivors are suffering from motor impairment. Ankle rehabilitation exercises act an important role in recovering patients’ walking ability after stroke. Currently, patients mainly perform ankle exercise to reobtain range motion (ROM) and strength the joint under a therapist’s assistance by manual operation. However, therapists suffer high work intensity, most existed devices focus on functional training ignore importance neurological early stage. In this paper,...

The hemiplegic rehabilitation state diagnosing performed by therapists can be biased due to their subjective experience, which may deteriorate the effect. In order improve this situation, a quantitative evaluation is proposed. Though many motion analysis systems are available, they too complicated for practical application therapists. paper, method detecting of human lower limbs including all degrees freedom (DOFs) via inertial sensors proposed, permits analyzing patient’s ability. This...

It has become a trend that ankle rehabilitation robots replace traditional therapist in field. Many have been proposed for training by researchers.

With the development of aging society, number hemiplegia patients grows rapidly and over 75% survivors suffering need rehabilitation training. To assist therapists, series training robots were carried out. However, most current researches are only focusing on function They ignore importance neurological in early phrase hemiplegia. Early takes a fundamental position whole-body rehabilitation. fulfill all those requirements, MKA have been developed. During experiment, there is some problems...

Nowadays, with the development of proportion elderly population in world, several problems caused by aging gradually into people's horizons. One biggest plagued vast majority is hemiplegia, which leads to vigorous physical therapists. However, these traditional methods therapy mainly rely on skill In order make up defects methods, many research groups have developed different kinds robots for lower limb rehabilitation training but most them can only realize passive cannot adopt based...

With the developments of robotics, it has become a fashion trend that ankle rehabilitation robots assist traditional training in field. In this thesis, novel robot combing with 3 degrees freedom, combining passive-active training, subjective awareness and objective was proposed. Prior to developments, requirement analyzed based on structure rehabilitation. order acquire range motion, an experiment established detect physiological data. Based therapy, robot-assist therapy requirements...

Abstract Alzheimer’s disease (AD) is the most common among elderly people and a major social medical problem. Amaryllidaceous alkaloids, acting as acetylcholinesterase inhibitors, represent potential treatment of AD. However, they also have some deficiencies, such extensive toxicity widespread side effects. In order to improve bioavailability reduce toxic effects, brain targeting amaryllidaceous alkaloids was enhanced by considering low density lipoprotein (LDL) receptors blood-brain barrier...
