Sensory conduction of the sural nerve in polyneuropathy.
Using surface electrodes, sensory nerve action potentials (SAP) have been recorded in the proximal segment (mid-calf to lateral malleolus) and the distal segment (lateral malleolus to toe 5) of the sural nerve and in the median nerve in 79 control subjects. The values obtained for the distal segment of the sural nerve varied widely and in seven apparently normal subjects no SAP could be disting...
متن کاملTwo-segment sural nerve conduction measurements in polyneuropathy.
Sensory conduction velocity of the sural nerve was measured in 50 normal subjects and 100 consecutive patients with suspected or established diagnosis of peripheral neuropathy. The sensory action potential was recorded by the orthodromic technique for the distal and the proximal segments. In the patient group, sensory conduction of the proximal segment appeared to be more consistent and easier ...
متن کاملSural and Radial Sensory Responses in Patients with Sensory Polyneuropathy.
INTRODUCTION The sural/radial nerve amplitude ratio (SRAR) is the quotient of the sensory nerve action potential (SNAP) amplitudes (Amp) of the sural and the superficial radial nerve. It has been hypothesized that this ratio can be used for the detection of early axonal loss, because the sural SNAP amplitude will decrease first, thereby also decreasing the SRAR value. OBJECTIVES To determine ...
متن کاملNerve conduction in alcoholic polyneuropathy.
SYMMMS of alcoholic Peripheral neuropathy were first recognized by ' S Lettsom (1787) who described hypermsthesiae and paralysis, affecting the ` r legs more than the arms. He, and later Jackson (1822), delineated the late ^ ^y ^ G^ `^ stage of peripheral nerve affection. Much clinical observation since then ','^ .c 0 has shown that the neuropathy in alcoholics varies widely in seve rity. We S ...
متن کاملUltrasonographic Evaluation of Sural Nerve for Nerve Conduction Study
OBJECTIVE To understand various morphologic types and locations of the sural nerve (SN) that are important for nerve conduction studies or nerve grafting procedures. The aim of this study was to describe the course and variations of the SN based on ultrasonographic findings for an adequate nerve conduction study. METHODS A total of 112 SNs in 56 volunteers with no history of trauma or surgery...
