Focal Vibration Alters Human Digital Sensory Nerve Action Potentials: A Pilot Study

Figure 2

Digit 3 SNAP. (a) Recordings from subject 14, the amplitude of SNAP reduces with the similar extent (52.4.0% vs. 54.1%) at the two different stimulation intensities. The SNAP amplitude regains its baseline value after vibration. (b) Recordings from subject 3, illustrating a smaller reduction of digit 3 SNAP amplitude when vibration applied to the MCPJ of digit 5 (62.9%) in comparison with the greater reduction when vibration to the MCPJ of digit 3 (31.5%). No notable changes of the onset latencies during or after vibration.
