| Popis: |
The reflex electromyographic responses to stretch of biceps and triceps muscles in the human arm have been examined using small-amplitude random displacements of the forearm, which produce flexion and extension at the elbow joint. The method of input-output cross-correlation allows the reflex system to be characterised in terms of its impulse response. Only those components of the output signals (biceps or triceps electromyogram) which are systematically related to the random muscle stretch contribute to the response, so that by using a task of sufficient duration a small response can be recovered from a substantial level of background noise. The approach offers several advantages: the use of small displacements for which the response appears linear, separation of automatic reflex components from voluntary components, and a potentially simple method for examining reflex responses in neurological patients. |
