Assessment of the prerequisite skills for cognitive behavioral therapy in children with and without autism spectrum disorders.

The purpose of this study was to assess the cognitive skills of children with autism spectrum disorders (ASD) thought to be necessary for Cognitive Behavioral Therapy (CBT). Forty children with ASD and forty age-matched typically developing children between the ages of 7-12 years participated. Groups were comparable with regard to nonverbal IQ, but children with ASD had significantly lower verbal IQ.

Reassurance seeking and depression in adults with mild intellectual disability.

Background: Adults with intellectual disability (ID) experience a high prevalence of depression. Yet, little research has investigated interpersonal processes related to depression in this population. In the general population, depressed persons behave in ways that elicit negative and rejecting reactions from others.

An implant for chronic selective stimulation of nerves.

An implantable stimulator system has been developed for nerve stimulation. The system is capable of stimulating selectively, either by fibre position, fibre size or by sending action potentials in one direction only, based on the use of nerve cuffs. The stimulator produces either quasi-trapezoidal current pulses, to allow anodal blocking, or conventional rectangular-shaped current pulses, of amplitude 20 microA to 5 mA (in 20 microA steps) with duration of 16 micros to 1 ms (in 8 micros steps).

Control of FES thumb force using slip information obtained from the cutaneous electroneurogram in quadriplegic man.

A tetraplegic volunteer was implanted with percutaneous intramuscular electrodes in hand and forearm muscles. Furthermore, a sensory nerve cuff electrode was implanted on the volar digital nerve to the radial side of the index finger branching off the median nerve. In laboratory experiments a stimulation system was used to produce a lateral grasp (key grip) while the neural activity was recorded with the cuff electrode.

Restoration of lateral hand grasp using natural sensors.

A closed-loop control system for controlling the key grip of a C6 tetraplegic patient was developed. Natural sensors served as the source of the feedback signal. The neural signals from cutaneous receptors were picked up by an implanted cuff electrode placed around the radial branch of the median nerve innervating the lateral part of the index finger.
