RESULTS
Those patients who had symptomatic relief with no wheezing on auscultation with increasing no change in PFR were classified under improved category (I) 78 episodes. Those who felt partially improved symptomatically but had their PFR reduced or those in whom wheezing reduced were called partially improved (PI) group (21 episodes). No change (NC) group consisted of, 10 episodes.
There is a statistically significant improvement in PFR in the group as a whole and in improved groups, there is no significant change in PFR in the other categories. The average time taken is least for the I group and maximum for the NC group.
The low values of the correlation coefficient 'r' in Table 3 shows that there is no correlation between the initial PFR values and the time taken for yoga-chair-breathing in any of the groups.
Table II PER changes and Average time taken for completing yoga - chair - breathing
 The results of the students paired 't' test for PFR change are shown in Table 2 for all the groups. Table III Correlation coefficient between initial PER before attack and time in minutes
 The Table 4 depicts the results of the analysis of variance (anova) between the groups I, PI aqnd NC and their initial PFRs. Table IV 'F' values showing that the differences in Initial PFR's in different groups are insignificant.
 The low 'F' value shows that the differences are not significant. Hence the improvements or otherwise after yoga-chair-breathing does not depend on initial PFR as observed in this study of acute episodes.
