CLEVERarm (Compact, Low-weight, Ergonomic, Virtual/Augmented Reality Enhanced Rehabilitation arm) is a novel exoskeleton with eight degrees of freedom supporting the motion of shoulder girdle, glenohumeral joint, elbow and wrist. Of the exoskeleton’s eight degrees of freedom, six are active and the two degrees of freedom supporting the motion of wrist are passive. This paper briefly outlines th...

Methods patients with JIA and active wrist arthritis who started receiving a second line therapy (DMARDs or biological agent) at the study Unit between 2008 and 2010 were enrolled in the study. The clinically more affected wrist was studied with MRI (1.5 T), US and conventional radiography (CR), coupled with standard clinical assessment at the study enrollment and after 1 year. Patients were ch...

OBJECTIVE Using ultrasonography (US) to guide botulinum toxin type A (BTX-A) injection in patients with post-stroke wrist and finger flexor muscle spasticity and assessing clinical outcomes after the injection and rehabilitation intervention. METHODS Twenty-three patients with wrist and finger spasticity after stroke were recruited in this study from May 2012 to May 2013. Under US guidance, t...

In semi-active suspension control, comfort and road holding are two essential but conflicting performance objectives. In a previous work, the authors proposed an LPV formulation for semi-active suspension control of a realistic nonlinear suspension model where the nonlinearities (i.e the bi-viscous and the hysteresis) were taken into account; an H∞/LPV controller to handle the comfort and road ...

BACKGROUND In patients who have an injury of the cervical spinal cord, the brachioradialis tendon may be transferred to the extensor carpi radialis brevis tendon to restore voluntary wrist extension. We hypothesized that the active range of motion of the wrist depends on the position of the elbow after this transfer because the brachioradialis changes length substantially during elbow flexion, ...

DURING the operation of perforating graft of the cornea, the trephine in the great majority of cases enters the anterior chamber in only a portion of its circumference, the remaining circumference of the graft being completed with scissors. The author has noticed, both in operations performed personally and in those performed by others, that the portion of the circumference of the trephine whic...

A 17‐year‐old male patient who was diagnosed with spastic cerebral palsy in his childhood came for seeking management of spasticity in his right upper limb. We found that he had typical presentations of MM in his right upper limb. Every time, when he was trying to extend his left wrist and fingers, his right wrist and fingers extended simultaneously. However, active motion of the right wrist an...

Identifying finger and wrist flexion based actions using single channel surface electromyogram have a number of rehabilitation, defence and human computer interface applications. These applications are currently infeasible because of unreliability in classification of sEMG when the level of muscle contraction is low and when there are multiple active muscles. The presence of noise and cross-tal...

The computer workstation is a ubiquitous tool in the office work environment; however, its use varies across many different tasks from surfing the Internet to typing. The question, therefore, is how does exposure to different physical risk factors for musculoskeletal disorders vary across tasks? Fifteen adults (10 females, 5 males) completed tasks simulating work at a computer workstation. The ...

In C7 to T1 or C8, T1 root avulsion palsies, restoration of finger active extension is not possible. Only tenodesis may restore hand opening in active wrist flexion. Many techniques have been described to restore this motion. In routine techniques, extensor tendons are fixed on radius or sutured on dorsal retinaculum. However, in these procedures, progressive tendon lengthening or ruptures may ...
