A Comparative Study to Evaluate the Effect of Crook Lying Position versus Sitting Position on Forced Vital Capacity (FVC) in Healthy Individuals.
To prove the effect of body position on the Forced Vital Capacity (FVC) and to find out the better position amongst the sitting and crook lying position as both are considered to be the best respiratory positions as far as FVC is concerned, but no research work is done to find out the better amongst the two.


METHODS
We analyzed the FVC of the randomly selected 100 subjects (both males and females) in sitting and crook lying position respectively. Computerized Pulmonary Function Testing (PFT) apparatus was used for analysis where three readings of FVC were taken in each position from which best ones were taken for analysis.


RESULTS
Mean FVC in crook lying position was found out to be 88.83% as compared to 99.07% in sitting position showing a difference of 10.24 %. The values were analyzed by using standard t-test which gave t-value 18.4316 and p-value 0.0001 which is statistically significant.


CONCLUSIONS
The results show that FVC was more in sitting position as compared to crook lying position.
