TABLE 4.

Sample contingency table, showing the distribution of the first quick flick performance in the first and second electromyograph (EMG) pelvic floor muscles (PFM) assessments in the biofeedback group (n = 50).

Performance of the first quick flicks	II EMG assessment (YES)	II EMG assessment (NO)
I EMG assessment (YES)	30	2
I EMG assessment (NO)	12	6

YES: the number of participants who activated the PFM first in order (correct technique); NO: the number of participants who activated the PFM after synergistic muscles or did not activate PFM at all (incorrect technique); PFMs, pelvic floor muscles; EMG, surface electromyography; analyzed with the Chi-square McNamara B/C test: p = 0.016.
