Reliable field was higher for video grp (47.5%) (p=0.033) & were more motivated (27%) (p=0.041). Video grp could perform the test better (40%) as compared to others (25% &25.5%). 85% patients in video grp felt instruction was helpful in performing the test (p=0.001),others (55.0% & 47.10%).Video grp (27.5%) were more relaxed compared to others (12.5% & 5.0%).
