What are Neuropathies Caused by Physical Forces?

Neuropathies Caused by Physical Forces
Neuropathies Caused by Physical Forces. Observation of collagen formation for rat sciatic nerve injury immediately (A, B) and on day 7 (C, D) after RF treatment under bright fields and polarized fields based on PR staining.RF, radiofrequency. PR, picrosirius red (collagen). (A) PR images of the sciatic nerve under bright field did not yield information about the degree of degeneration or destruction of CFs or NFs immediately after RF treatment. CO, control; SH, sham; PRF, pulsed RF; CRF, continuous RF. CF, collagen fiber = epi-perineurial layer; NF, nerve fiber = endoneurial layer. Scale bar = 200 µm. (B) PR images under polarized field clearly showed the formation of newly synthesized collagen (presence of yellow-orange birefringence). Scale bar = 200 µm. (C) PR images of the sciatic nerve under bright field on day 7 after RF treatment. Scale bar = 200 µm. (D) Newly synthesized collagen formation was examined in all groups under the polarized field. Scale bar = 200 µm. Data shown are the mean and SD of six mice (n = 18). Internal-specific morphological analysis of sciatic nerve fibers in a radiofrequency-induced animal neuropathic pain model: Choi S, Choi HJ, Cheong Y, Lim YJ, Park HK - PloS one (2013). Not altered. CC.

Neuropathies caused by physical forces are neuron damage due to physical disturbances.

Neuropathies caused by physical forces include: 

  • Neuropathy due to avulsion
  • Carpal tunnel syndrome
  • Neuropathy due to compression
  • Neuropathy due to laceration
  • Ulnar nerve entrapment 
  • Compression neuropathy of the radial nerve
NEUROPATHIES CAUSED BY PHYSICAL FORCES   
NEUROPATHYSIGNS/ SYMPTOMSTREATMENT PROGNOSIS
Neuropathy due to avulsionWeakness, inability to use certain muscles, total lack of movement, Nerve transfer, Fair if the repair is delayed and it can lead to total loss of function.
Carpal tunnel syndromeNumbness, tingling, weakness, muscle damage, pain, Wrist brace, positioning, reduce swelling, ergonomics,vitamin B6, median nerve gliding exercise. Good as it can be manageable with treatment.
Neuropathy due to compressionNumbness, tingling, weakness, muscle damage, pain,Reduce compression, NSAIDS, corticosteroids, Good but may only cause permanent nerve damage and loss of function.
Neuropathy due to lacerationInability to sense pain, numbness, tingling sensation, difficulty in walkingSuturing.Fair since it has good recovery once surgery is done.
Ulnar nerve entrapmentPain, numbness, tingling, loss of muscle mass, weaknessOccupation therapy, splints, pain medicationFair since one can have full recovery.
Neuropathy due to radial nerve compressionWeakness of the fingers, loss of finger coordination, inability to straighten and stretch the arm.Nsaids, corticosteroids, supportive splint, physical therapy.Good since one recovers after treatment
