Method for improving motor control in an individual by sensory training

摘要

A method and apparatus for implementing a training regimen which addresses motor control problems accompanied by sensory degradation. Accordingly, the training regimen is applicable to motor control disorders associated with a variety of different causes, including traumatic injury, disease, aging and gradual “occupational” type injury. For example, in an individual suffering from repetitive strain injury (RSI), the disabling motor control problems are often accompanied by sensory problems. These sensory problems appear to be caused over time by harmful attended rapid repetitive movements resulting in undesirable changes in the somatosensory, proprioceptive and/or kinesthetic ability of the affected regions of the individual. The present invention hypothesizes that repetitive delivery of simultaneous or nearly simultaneous afferent sensory inputs, under attended conditions of high cognitive drive, results in a learning-induced integration of the representation of the individuality of otherwise differentiable parts of the subjects thereby degrading the sensory feedback loop necessary for normal motor control. What started out as a degradation of the sensory feedback capability, essential for proper motor control, eventually manifests over time as a motor control problem. Thus, motor control problems which are accompanied by sensory degradation can be alleviated by a regimen of remedial re-differentiating sensory training of the affected regions of the individual. Accordingly, the training regimen differentially stimulates two locations within the afflicted portion of the individual. Feedback from the individual indicates the degree of difficulty the individual has in sensing differentially between the two locations. The stimulation is then adapted to the individual based on the feedback. Adaptation includes increasing the distance between the two locations and/or changing the spectral or temporal characteristics of the stimuli.
