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.

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.

Summary
Brief summary
The Fetal Kicks is a novel device developed by Monash MIME to monitor fetal movement. For the following study, the current phase entails a proof of concept in women antenatally to assess the quality of signals obtained on Fetal Kicks. For this, Fetal Kicks will be utilised together with the conventional cardiotocography (CTG) to ascertain the equivalence of Fetal Kicks with conventional fetal movement counting

Aims
1. Accurately corroborating maternal perceptions of movements on the CTG (via sensor imprints) to device captures of fetal movements
2. Accurately corroborating maternal perceptions of movements on the ultrasound (via sensor imprints) to device captures of fetal movements

Research design
The following study is a cross sectional survey with a cohort design. The following design has been chosen as it is considered to be the design of choice in evaluating a diagnostic test- in this case, Fetal Kicks. Utilising the following design, measurements of test accuracy and precision will be carried out on Fetal Kicks in comparison to CTG and conventional fetal movement countings.

Primary Outcomes
1. Correlation between the signals obtained from Fetal Kicks and routine cardiotocography over a similar time period. This will be done electronically utilising cross correlation.
2. Correlation between the information obtained from Fetal Kicks and CTG as interpreted by clinicians. This will be measured on a CTG reporting tool designed specifically for the study.

Secondary Outcomes:
1. 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
