Effects of Wrist Posture and Fingertip Force on Median Nerve Blood Flow Velocity.

摘要: Purpose. The purpose of this study was to assess nerve hypervascularization using high resolution ultrasonography determine the effects wrist posture and fingertip force on median blood flow at in healthy participants those experiencing carpal tunnel syndrome (CTS) symptoms. Methods. nerves nine symptoms CTS were evaluated optimized five postures with without a middle digit press (0, 6 N). Results. Both had significant main mean peak velocity. Blood velocity neutral (2.87 cm/s) significantly lower than flexed 30° (3.37 cm/s), 15° (3.27 cm/s), extended (3.29 cm/s). Similarly, (2.81 cm/s) (3.56 cm/s). A difference not found between groups. Discussion. Vascular changes associated may be acutely induced by nonneutral force. This represents an early evaluation intraneural as measure response occupational risk factors advances our understanding vascular phenomena peripheral compression.
