Vatavyadhi Chikitsa: Difference between revisions

''Gridhrasi'': ''Gridhrasi'' is a ''snayugata'' (affecting tendon) ''roga''. The word ''gridhrasi'' is derived from ''ghridhra'', which means vulture, the typical gait of the disease is highlighted by the name.  The patient’s gait is changed like a vulture due to affected tendons by vitiated ''vata''.   

''Khalli'' is the term given to severe painful twisting conditions of tendons. (verse 56-57)

Nomenclature of diseases: All the ''vata'' disorders cannot be named or explained. They should be understood on the basis of site of affliction as well as nomenclature. (verse 58)

Diagnosis of ''dhatukshaya'' (degenerative pathology) and ''avarana'' (obstructive pathology) induced vitiation of ''vata'': ''Vata'' can be vitiated due to ''dhatukshaya'' and ''margavarana'' types of pathogenesis. ''Dhatukshaya'' leads to depletion of tissues and more space for ''vata'' to move. This leads to ''gatavata'' phenomenon. ''Avarana'' of ''vata'' can be caused by other ''dosha'' or ''dhatu''. So the differences between ''avarana'' and ''gatavata'' should be understood.

The word, ''avarana'' means obstruction or resistance or friction to the normal ''gati'' of ''vata''. Hence when its normal movement is hampered or vitiated, it becomes ''avrita'' and leads to different disorders. The ''gatatva'' and ''avritatva'' are entirely different phenomenon. Here an attempt is being made to differentiate the both physio-pathologies. [16]

 

#In ''avarana'', generally the vitiation of ''vata'' is passive. When vitiated ''dosha'' or any other thing obstructs the pathway of ''vata, avarana'' happens. Normal state of ''vata'' gets vitiated as ''avarana'' progresses. The substance which obstructs the pathway of ''vata'' is called as ''avaraka'' and the ''dosha'' (''vata'' in general or its components) affected by ''avarana'' is called as ''avariya'' or ''avrita''. Normally the ''avarana'' is caused by the etiological factors for the vitiation of ''avaraka''. Etiological factors for the vitiation of ''vata'' (''sva nidana'') will be absent. In case of ''gatavata'' the vitiation of ''vata'' will be active. Here its own etiological factors are operating in the vitiation of ''vata'' in the pathogenesis and the vitiated ''vata'' adopts specific pathway and abnormally localizes at particular sites.

#In the process of ''avarana chala'' property of ''vata'' is diminished due to obstruction. Other properties are not involved in the process of obstruction. But in case of ''gatatva'' the vitiation of ''vata'' takes place by involvement of other properties like ''ruksha, laghu, khara, vishada'' etc along with ''chala''.

#In ''avarana'' the ''gati'' of ''vata'' is obstructed partially or fully. Once gets obstructed the ''vata'' may simply get lodged there (''baddha marga, margarodha''), try to nullify the obstruction, may get covered by the obstructing substance (''avrita''), adopt an opposite direction (''pratiloma'') or alter the direction (''viloma''). The different terminologies have been used to denote ''avarana'' in different contexts according to the nature of ''avarana'' and the state of ''vata'' and ''marga'' (passage). In case of ''gatatva'' the ''gati'' of vitiated ''vata'' aggravated and starts moving abnormally leading to localization at particular sites.

*''Avarana'' is caused by ''purnata'' (filling) of other ''dosha'' in the ''srotas/marga'' (passage) of ''vata''. In ''gatatva'' the ''srotas'' or sites of occupation of ''vata'' are ''rikta'' (unfilled or spacious) and the aggravated ''vata'' fills the ''srotas''/site.
