Electrically evoked long loop responses (LLR): normative data for upper and lower extremities
Abstract:
Long loop responses can be obtained repeatedly in all neurologically healthy subjects with low variability of onset and peak latencies. Long loop responses showed characteristic features separate from microreflexes of Bickford. Normative data will help us to elucidate the characteristic alterations of these reflexes in different pathologies which involve somatosensory pyramidal and extrapyramidal systems.
