To determine if certain fetal echocardiogram (f-echo) characteristics correlate with grasp and pincher (GaP) strength values in fetal cardiac sonographers (f-CS).
Approach:
Statistical Analysis: Univariable mixed-effects regression models were used to analyze changes in GaP strength pre- and post-f-echo, with p-values interpreted to indicate the strength of association.
Key Findings:
A total of 304 f-echo procedures were performed by 9 female f-CS.
Pre-grip strength for the dominant hand was 26.2 kg and post-grip was 25.9 kg.
Pre-pincher strength for the dominant hand was 6.0 kg and post-pincher was 5.9 kg.
Minimal changes in GaP values were observed pre-and post-f-echo.
A significant negative correlation was found between grip strength change and maternal BMI.
Interpretation:
The study suggests that while there are minimal changes in GaP strength pre- and post-f-echo, maternal BMI may influence grip strength changes.
Limitations:
Small sample size of 9 female f-CS.
Limited to singleton and twin pregnancies, which may not generalize to other populations.
Only a preliminary assessment without extensive longitudinal data.
Conclusion:
The findings indicate a potential link between maternal BMI and GaP strength changes, warranting further investigation.
