Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will utilise routine cardiotocography (CTG) by obstetrician to monitor the fetal movements of the fetus antenatally. At the same time, a novel device , the Fetal Kicks will be attached to their abdomen to monitor the fetal movement as well. Fetal Kicks utilises a strain gauge sensor to monitor the fetal movements. For this study, Fetal Kicks will not be utilised to guide care and only for passive monitoring. This process will take place for a duration of 30 minutes. Fetal Kicks monitoring will only occur on a single occasion only in each participant.
Intervention code [1] 297242 0
Diagnosis / Prognosis
Comparator / control treatment
Cardiotocography (CTG) ,ultrasound based assessment of fetal movement and maternal reporting of fetal movement will be carried out on a single occasion for a duration of 30 minutes at the same time as the intervention device.
Control group
Active

Outcomes
Primary outcome [1] 301169 0
Correlation between the signals obtained from Fetal Kicks and routine cardiotocography over a similar time period. This will be done electronically utilising cross correlation.
Timepoint [1] 301169 0
Data is collected immediately at the end of each monitoring period of CTG
Primary outcome [2] 301170 0
Correlation between the signals obtained from Fetal Kicks and ultrasound imaging. This will be compared utilising cross correlation.
Timepoint [2] 301170 0
Data is collected immediately at the end of each monitoring period of CTG
Secondary outcome [1] 331942 0
Patient view on Fetal Kicks (i.e pros, cons, will they recommend it, areas for improvement etc.). This will be measured through a questionnaire designed specifically for the study
Timepoint [1] 331942 0
Data is collected immediately at the end of each monitoring period of CTG
Secondary outcome [2] 332894 0
Sensitivity, specificity, negative predictive value and positive predictive values of Fetal Kicks in comparison to CTG
Timepoint [2] 332894 0
Data is collected immediately at the end of each monitoring period of CTG

Statistical methods / analysis
For the following study, a sample size of 50 was estimated based on similar proof of concept studies. This was based on the assumption that the level of a was set at 0.05 and a power of 90% This was based on an estimated recruitment rate of 55 with non responders of 10%.
For the primary objective, statistical tests will be utilised to test the device agreement with routine CTG for measurement of the fetal movement considered to be the gold standard.
For device concordance, outputs on Fetal Kicks and the CTG, ultrasound and maternal reports of fetal movement will be measured and compared electronically using cross correlation. Signal to Residue Ratio (SRR) will be used to compare similarity and how much different the signal from Fetal Kicks is from the control and a Root Mean Square Error (RMSE) will be used for the error for each point in the plot. For UA, a cross correlation statistic will be utilised.
Measurement of device diagnostic accuracy will be made by calculating the sensitivity, specificity negative predictive value and positive predictive values of Fetal Kicks to regular CTG. This will be done by comparing the assessments by clinicians of the CTGs through the reporting tool provided.
