Imitating human motion using humanoid upper body models
… motion imitation of five different humanoid upper bodies (comprised of the torso and upper limbs) using human dance motion as a case study. The humanoid models are based on five existing humanoids, namely, ARMAR, HRP-2, SURALP, WABIAN-2, and WE-4RII. These humanoids are chosen for their …

The effect of work related mechanical stress on the peripheral temperature of the hand
… to the development of conditions that affect the upper limbs. Repetitive Strain Injury is one classification of those conditions which is related to overuse of repetitive movement. Hand Arm Vibration Syndrome is a subtype of this classification directly related to the operation of instruments and …

Exploring lateralized sensorimotor processing using somatosensory evoked potentials
Differences exist between the two upper limbs in the chosen motor control strategy when moving in dynamic environments. To date, a large body of literature has explored these differences but few studies have incorporated neurophysiological data to support their findings. By utilizing somatosensory …

Nintendo Wii versus resistance training to improve upper-limb function in children ages 7 to 12 with spastic hemiplegic cerebral palsy: a home-based pilot study
… a Nintendo Wii intervention to a single-joint upper-limb resistance training of a similar intensity, in n=6 children ages of 7 to 12 with spastic hemiplegic CP with respect to upper limb function, compliance and motivation levels. The main results found that all participants in the Wii …

Shoulder pain and cycle to cycle kinematic spatial variability during recovery phase in manual wheelchair users
… at each speed. Motion capture data of the upper limbs were recorded. Intra-individual kinematic spatial variability of the steady state wrist motion during the recovery phase was determined using principal component analysis (PCA). The kinematic spatial variability was calculated at every …

The design and development of an upper limb assistive technology
… integrated technologies; patients with limited upperlimb mobility due to paresis, may finally have the opportunity to regain normal movement. An effective yet portable upper limb assistive orthosis has not yet been developed to rehabilitate these patients. A portable device would allow users to …

Influence of rear wheel tire type on wheelchair propulsion biomechanics
… speed using five different pairs of tires. Upper limb and trunk kinematics, perceived exertion, stroke pattern and the temporal characteristics of propulsion were measured. When using pneumatic (air filled) tires, with lower rolling resistance, participants had lower push frequency (p < …

Effects of metamorphism and structure on aeromagnetic anomalies over the Carolina slate belt near Roxboro, North Carolina
… fold structure in some locations and by only the upper limbs of the structure in others. Two alternative explanations are proposed: (1) the deeper part of the fold may have been displaced by thrusting, (2) metamorphic grade may increase with depth so that magnetic susceptibility contrasts diminish …

Surfing injuries in recreational surfers
… sprains (3%), and joint dislocations (1%). Lower limbs are the most commonly injured area, followed by upper limbs, and the head and face. Surfing safety equipment should be designed to protect the limbs from lacerations, and aid in the prevention of serious injuries such as vertebral, facial and …
