Disease relevance of Peroneal Nerve

• Burning pain was induced in healthy human subjects by intracutaneous injections of capsaicin (20 microl, 0.1%) in the innervation territory of the cutaneous branch of the peroneal nerve and the pain responses were compared with the activation patterns of afferent C-fibres recorded by microneurography [3].

Biological context of Peroneal Nerve

• Nerve conduction findings were consistent with a demyelinating neuropathy in 77% of patients reactive to myelin-associated glycoprotein and 24% with unknown reactivity (p < 0.0001) and the mean conduction velocity of peroneal nerve was lower in the former group (22.9 m/sec) than in the latter group (39.6 m/sec) (p < 0.000001) [14].
• We recorded muscle sympathetic nerve activity (microneurography, peroneal nerve), forearm blood flow, heart rate, and blood pressure in 13 borderline hypertensive subjects during a 1-hour insulin infusion (38 microunits/m2/min) while holding blood glucose constant [15].
• In nine sedentary subjects (16.5 +/- 0.4 years, mean +/- SEM) we measured blood pressure (Finapres device), heart rate (electrocardiogram), and postganglionic muscle sympathetic nerve activity (microneurography from the peroneal nerve) at rest and during intravenous infusion of phenylephrine and nitroprusside [16].
• 1. The axonal transport of acetylcholine (ACh), choline acetyltransferase (ChAc) and cholinesterase (ChE) was estimated in the peroneal nerves of rabbits by measuring the accumulation of each against a nerve crush over a period of 20 hr [17].
• Specifically, we investigated the actions of group I synergistic and antagonistic muscle afferents (e.g. common peroneal nerve, CPN; medial gastrocnemius, MG) and tactile plantar cutaneous afferents on the soleus H-reflex during controlled hip angle variations in 11 motor incomplete spinal cord injured (SCI) subjects [18].

Anatomical context of Peroneal Nerve

• Homozygous EphA4 mutant animals show peroneal muscular atrophy correlating with the absence of the peroneal nerve, the main dorsal nerve of the hindlimb [19].
• In the diabetic group overall, there was a strongly positive linear correlation between vascular response to noradrenaline and conduction velocity in both the median nerve (r = 0.62, p = 0.0009) and peroneal nerve (r = 0.53, p = 0.006) [20].
• Increased endothelial cell area and reduced luminal size were related to a reduced peroneal nerve conduction (p < 0.05, p < 0.01, respectively), reduced myelinated fibre density (p < 0.05, p < 0.01) and elevated thermal perception (p < 0.05, p < 0.001) [21].

Associations of Peroneal Nerve with chemical compounds

• To determine whether this response is related to sympathetic activation, we studied the cardiovascular and respiratory effects of adenosine in normal subjects while measuring muscle sympathetic nerve traffic through direct recordings from a peroneal nerve [24].

• 4. Direct electrical stimulation of the denervated soleus muscle caused plaques of true AChE, as determined by inhibitor studies, to appear in muscles where the fibular nerve had been cut 2-4 days after the soleus nerve but not in muscles where the two nerves had been cut at the same time [35].
• In each subject, over a 10 min supine period, we measured mean arterial pressure (Finapres), heart rate (electrocardiogram), venous plasma norepinephrine (high-performance liquid chromatography) and efferent postganglionic muscle sympathetic nerve activity (microneurography at a peroneal nerve) [36].
• Denervation of the EDL muscle by section of the peroneal nerve 10-20 mm from its entrance to the muscle caused G6PD activity to increase to 170% of control by day 1 and to 200% and 180% of control by days 2 and 4, respectively [37].
• METHODS: In 14 healthy, young (age 20-31 yr) volunteers, arterial pressure was measured from the radial artery, forearm blood flow was derived by strain gauge plethysmography, and sympathetic nerve activity (SNA) directed to skeletal muscle blood vessels was recorded from a tungsten needle placed percutaneously into the peroneal nerve [38].
