16. NERVE RECOVERY AND REGENERATION=
After nerve injury, the nerve will try to repair itself by sprouting regenerating nerve units
These regenerating units will then try to grow down the nerve to reinnervate (restore nervous
function to)muscle or skin.
If they make correct connection- motor nerve to muscle or sensory nerve to skin- then recovery
of muscle function and skin sensation will occur.
If the regenerating nerve fibers do not make a correct connection, then no recovery will occure

23. c)MONONEUROPATHY, MONONEURITIS MULTIPLEX & POLYNEUROPATHY =
1. Mononeuropathy- (involvement of single nerve) trauma, neoplastic infiltration.
2. Multiple mononeuropathy or mononeuritis multiplex â (damage to multiple
nerves) ischaemia, DM.
3. Polyneuropathy- (symmetrical distal and sensory deficits)
24. ⢠Pathophysiology = 1. Axonal degeneration
Axonal degeneration originate at the most distal extent of the axon.
Axonal degenerative polyneuropathies are usually symmetrical
distal-to-proximal
Axonal degeneration is the most common type of pathologic reaction in generalized
polyneuropathies, and it is often attributed to a metabolic cause.
disorder progresses
25. 2. Segmental demyelination
Segmental demyelination refers to focal degeneration of the myelin sheath with
sparing of the axon
seen in focal mononeuropathies and in generalized sensorimotor or predominantly
motor neuropathies
Acquired segmental demyelinating polyneuropathies are immune-mediated or
inflammatory in origin also occur in some hereditary polyneuropathies.
26. ⢠In peripheral nerve disorders that are characterized by axonal
degeneration, prognosis is less favorable because the axon must
regenerate and reinnervate muscle, the sensory organ, blood vessels, and
other structures before clinical recovery is noted.
⢠Recovery may be more rapid with segmental demyelination because
remyelination is accomplished more quickly, thereby re-establishing
normal conductivity of the axon and return of function.
27. ⢠INVESTIGATIONS :
1. Nerve conduction study
2. Nerve biopsy
3. CBC with ESR
4. Thyroid function test
5. Blood sugar
6. Vitamin B12
48. ⢠MODE OF ACTION of Pada abhyanga, Abhyanga, Savahan =
Lack of blood circulation is one of the reason for impaired sensations and the altered
blood flow causes improper oxygen and nutrient supply to the nerves. Abhyanga by its
mechanical maneuver produces heat and causes vasodilation which improves circulation
there by gives symptomatic relief.
Dravya=Tila taila, Narayan taila, Mahanarayan taila, Maha vishagarbha taila, Dhanvantar
taila, Bala taila, Nirgundi taila etc
Chimchimayan â ksheerabala taila and pinda taila can be used â vata pitta shamak
Suptata- sahacharadi taila , maha vishagarbha taila âvata kapha shamak can be used.
52. MODE OF ACTION OF UDVARTAN =
⢠Udvartan therapy is the transmission of energy in the form of motion with pressure.
Deep pressure massage helps the interchange of tissue fluids by increasing the circulation in the
superficial vein and lymphaticâs and helps in mechanical stimulation causing muscles to contract
It increases circulation mainly in the veins, the alternate pressure and relaxation brings fresh blood
to the part and improves the nutrition of the particular area
Increased blood supply because of the vasodilatation stimulates both motor and sensory nerve
endings to various parts of the body and increase metabolism by which the toxins and free radicals
which are responsible for the formation of the disease are excreted out of the body.
53. Types of udvartan=
1.Udgharshan( churna with out Sneha ) sira mukha visaran , twakasta agni vardhan
2.Utsadan(churna + Sneha )
Dravya= Kolkulathadi churna, Musta churna, triphala churna, rasna churna.
54. MODE OF ACTION OF BASTI=
Basti is called as ardha chikitsa( Ch. Si 1/ 38-39)
58. MODE OF ACTION OF NASYA=
Dravya=
1.Anu taila
2.Goghrita
3.Yashtimadhu
ghrita
4.Amrutadi taila
5.Ashwagandha
taila
6.Vacha churna
etc
59. MODE OF ACTION OF PARISHEK=
Its dual action of Snehan-Swedan assists in alleviatingVata effectively.
TheVata Dosha is responsible for many type of Shool (Pain) has almost opposite qualities to Sneha.
Thus Parishek Sweda normalizes the vitiatedVata Dosha and helps in SampraptiVighatana of Shoola
As Parisheka avails the effect of both Snehan and Swedan, Snehan corrects the Shushkata of the Dhatu
(which is the root cause forVata vitiation), imparts strength and provides platform for performing Swedan
Swedan relieves Ruka ( symptoms ofVata ) and soften the body parts
Repeated uses of Parishek Swedan are essential for controlling theVata and to restore in its normal
functions.
