Lower-limb exoskeletons have been proven to be beneficial for motor function disability patients, in both clinical rehabilitation settings and daily activities. However, the pediatric field are still very limited. In this paper, a novel lower-limb exoskeleton design children is presented. Based on anthropometric data of target group, size designed adjustable suit from 8 12 years old. It employs...

This paper presented the mechanical design and control of a lower limb rehabilitation exoskeleton named “the second (LLRE-II)”. The with lightweight mechanism comprises 16-cm stepless adjustable thigh calf rod. LLRE-II weighs less than 16 kg has four degrees freedom on each leg, including waist, hip, knee, ankle, which ensures fitted wear comfort. Motors harmonic drives were installed joints hi...

A typical man–machine coupling system could provide the wearer a coordinated and assisted movement by lower limb exoskeleton. The process of cooperative relies on accurate perception wearer’s human information planning control joint In this paper, neural network Long-Short Term Memory (LSTM) machine learning model method is proposed to predict actual trajectory body’s limbs. Then wearable angle...

The series elastic actuator (SEA) is generally used as the torque source of exoskeleton robot for human–robot interaction (HRI). In this paper, an impedance control method lower limb robots driven by SEA presented. First, considering low-frequency vibrations generated during walking, displacement regarded external disturbance to motor. An structure with negative stiffness (NSS) designed achieve...

Research into rehabilitation robotics has grown rapidly and the number of therapeutic rehabilitation robots has expanded dramatically during the last two decades. Robotic rehabilitation therapy can deliver high-dosage and high-intensity training, making it useful for patients with motor disorders caused by stroke or spinal cord disease. Robotic devices used for motor rehabilitation include end-...

In this letter, we introduce a novel control strategy called Virtual Energy Regulator (VER) for lower limb rehabilitation exoskeletons. Unlike the conventional trajectory tracking controllers, VER, which is time-independent controller, does not exoskeleton joints over reference trajectory. Instead, it imposes constraint to state-space and consequently creates limit cycle each joint. The propert...

objective(s): the aim of study was to determine history of genitourinary diseases in war related bilateral lower limb amputees who were injured during iran-iraq war (1980-1988).   methods: subjects with war related bilateral lower limb amputation (335 persons) were examined by two physicians for any history of genitourinary diseases and their documents were reviewed.   results: the mean age was...

introduction: estimation of stature is one of the most important fields in forensic medicine. also it is of particular interest to anthropologists and anatomist. our aim was to investigate the relationship between stature and the length of lower limb and foot to derive a regression formula for estimating the stature. methods: three anthropometric measurements stature, lower limb length (lll) an...

elephantiasis nostras verrucosa (env) is a rare condition in which hyperkeratosis, fibrosis and disfiguration of dermis occurs. it is caused mostly by non infectious diseases such as surgery, trauma, tumors, and venous obstructions. to our knowledge there is not any case report of env in middle east region. in this patient, env caused by trauma and patient presented with enlargement of right lo...
