Normal f wave latencies

Webof F waves and h reflexes are their presence and minimal latencies. Interpretation When interpreting NCS data, initial considerations are: • Is the compound potential normal in size and shape, or reduced? • Is the conduction velocity normal? Table 2 outlines key differences between NCS results in axonal loss and demyelinating processes. WebMinimum F wave latencies were determined in median, ulnar, tibial and peroneal nerves. The F min/He and F min/L ratios of each nerve were calculated. Results: F latencies of …

WebA neurologist has sent a patient for nerve conduction studies (NCS) and has received the report, but what does it mean? We hope to remove some of the mysteries that may surround NCS. The techniques and how they are affected by disease are described in general terms. These principles can be applied to specific conditions discussed elsewhere. We also … WebThe vestibulo-masseteric reflex (VMR or p11 wave), the acoustic-masseteric reflex (AMR or p1/n21 wave) and the mixed vestibulo-cochlear p11/n21 potential are responses of masseter muscles to sound that can be employed to evaluate brainstem function.
