Summary of "A Paradigm to Enhance Motor Imagery Using Rubber Hand Illusion Induced by Visuo-tactile Stimulus."

Enhancing motor imagery (MI) results in amplified event-related desynchronization (ERD) and is important for MI-based rehabilitation and brain-computer interface (BCI) applications. Many attempts to enhance MI by providing visual guidance have been reported. We believe that the rubber hand illusion (RHI), which induces body ownership over an external object, can provide better guidance to enhance MI; thus, an RHI-based paradigm with motorized moving rubber hand was proposed. To validate the proposed MI enhancing paradigm, we conducted an experimental comparison among paradigms with twenty healthy subjects. The peak amplitude and arrival times of ERD were compared at contralateral and ipsilateral EEG channels. We found significantly amplified ERD caused by the proposed paradigm, which is similar to the ERD caused by motor execution. In addition, the arrival time suggests that the proposed paradigm is applicable for BCI. In conclusion, the proposed paradigm can significantly enhance MI with better characteristics for use with BCI.

Rubber Hand Illusion Modulates the Influences of Somatosensory and Parietal Inputs to the Motor Cortex.

The rubber hand illusion (RHI) paradigm experimentally produces an illusion of rubber hand ownership and arm shift by simultaneously stroking a rubber hand in view and a participant's visually occlude...

Artificial hand illusions dynamics: Onset and fading of static rubber and virtual moving hand illusions.

The aim of this study was to investigate the temporal dynamics of two multisensory body illusions: a static rubber hand illusion (RHI) and a moving virtual hand illusion (VHI). We explored the onset a...

Dissociation of feeling and belief in the rubber hand illusion.

The Rubber Hand Illusion (RHI) has been widely used to investigate the perception of the bodily self. Commonly used measures of the illusion are self-report questionnaires and proprioceptive drift of ...

Affective certainty and congruency of touch modulate the experience of the rubber hand illusion.

Our sense of body ownership relies on integrating different sensations according to their temporal and spatial congruency. Nevertheless, there is ongoing controversy about the role of affective congru...

Deep Brain Stimulation for Parkinson's disease changes perception in the Rubber Hand Illusion.

Parkinson's disease (PD) alters cortico-basal ganglia-thalamic circuitry and susceptibility to an illusion of bodily awareness, the Rubber Hand Illusion (RHI). Bodily awareness is thought to result fr...

Motor Imagery Ability in Patients With Stroke

Motor imagery (MI) might be described as a dynamic process in which an individual mentally stimulates an action without any overt movement. After stroke, motor imagery ability is impaired ...

Effects of Motor Imagery and Action Observation on Electromyographic Activity and Intramuscular Oxygenation in the Hand Gripping Gesture

Motor imagery is defined as a dynamic mental process of an action, without its real motor execution. Action observation training consists of watching an action performed by someone else. T...

Motor imagery is the mental representation of movement without any body movement. According to recent studies motor imagery contains three strategies to mentally simulate the movements: in...

Recovery of Hand Function Through Mental Practice.

The purpose of this study is to assess the therapeutic benefits of motor imagery training in stroke patients with persistent motor weakness.

Use of Tendon Vibration and Mirror for the Improvement of Upper Limb Function and Pain Reduction

Upper limb paralysis following stroke is a very common problem. Only 30% of stroke patients who suffer from upper limb paresis experience a full recovery of function. There is a need for t...

Medical and Biotech [MESH] Definitions

The use of mental images produced by the imagination as a form of psychotherapy. It can be classified by the modality of its content: visual, verbal, auditory, olfactory, tactile, gustatory, or kinesthetic. Common themes derive from nature imagery (e.g., forests and mountains), water imagery (e.g., brooks and oceans), travel imagery, etc. Imagery is used in the treatment of mental disorders and in helping patients cope with other diseases. Imagery often forms a part of HYPNOSIS, of AUTOGENIC TRAINING, of RELAXATION TECHNIQUES, and of BEHAVIOR THERAPY. (From Encyclopedia of Human Behavior, vol. 4, pp29-30, 1994)

Sheets of latex rubber punched and placed over the teeth during dental procedures to isolate the field of operation from the rest of the oral cavity (Jablonski; Illustrated Dictionary of Dentistry, 1982). Rubber dams are useful in preventing the swallowing of instruments or restorations during dental work.

Coagulated exudate isolated from several species of the tropical tree Palaquium (Sapotaceae). It is the trans-isomer of natural rubber and is used as a filling and impression material in dentistry and orthopedics and as an insulator in electronics. It has also been used as a rubber substitute.

Allergic reaction to products containing processed natural rubber latex such as rubber gloves, condoms, catheters, dental dams, balloons, and sporting equipment. Both T-cell mediated (HYPERSENSITIVITY, DELAYED) and IgE antibody-mediated (HYPERSENSITIVITY, IMMEDIATE) allergic responses are possible. Delayed hypersensitivity results from exposure to antioxidants present in the rubber; immediate hypersensitivity results from exposure to a latex protein.

Deformities of the hand, or a part of the hand, acquired after birth as the result of injury or disease.
