Primary orthostatic tremor is characterized by 16-Hz motor activity that is coherent between muscles. It has been suggested that this tremor originates in the brain. This view is questioned by findings from a patient with complete paraplegia who experiences intermittent leg spasms at rest. The EMG activity within the spasms showed a 16-Hz component that was coherent between muscles unilaterally and bilaterally. This raises the possibility that the spinal cord could be the source of orthostatic tremor.
|Additional Information:||Implementing signal processing techniques to examine coherence in activity between muscles, it is suggested that tremor could arise from the spinal cord, whereas other research has suggested it to be supraspinal in origin. It's importance is in understanding neurological effects observed in paraplegic patients.|
