Sumario: | OBJECTIVE: The aim of the study was to determine the intra- and inter-rater reliability of palpation technique, digital calipers, and diastometer, as well as their concurrent validity against ultrasound imaging. METHODS: Ninety consenting parous women (20–45 years), recruited from a postnatal clinic in Enugu, Nigeria, participated in this observational study. Two physiotherapists and a sonographer measured their inter rectus distance at the level of the umbilicus, 4.5 cm above and below it, respectively, using each of the four modalities. The intra-rater measurements were taken at a week’s interval. Data were analyzed with descriptive and inferential statistics of intraclass correlation coefficient and paired samples T-test, at an alpha level set at P < 0.05. RESULTS: It showed the palpation technique (r = 0.749–0.967 and 0.658–0.917), digital calipers (r=0.750–0.955 and 0.685–0.904), and diastometer (r=0.762–0.958 and 0.471–0.902) demonstrated good inter- and intra-rater reliability. The concurrent validity of the palpation technique, digital calipers, and diastometer against the USI was poor at all three reference points. CONCLUSION: Palpation technique, digital calipers, and diastometer are reliable tools but not valid substitutes to ultrasound imaging for the clinical measurement of diastasis rectus abdominis. |
