Question: What is the intra and inter-rater reliability of the Valedo system to measure trunk range of motion (ROM) during performance of streamlined Wolf Motor Function Test (SWMFT) in stroke and age-matched healthy participants?
Trunk performance has been recognized as an important independent predictor of activities of daily living after a stroke. A recent study by Kwee 2015 showed that the trunk control measured by trunk impairment scale (TIS) is associated with upper limb (UL) function measured by SWMFT in subacute and chronic stroke. To ensure that any planned treatment for strokes is effective, therapists need accurate assessment tools or outcome measures to assess the change in function. The purpose of this study is improve assessment of trunk control in a clinical setting by testing the reliability of using a low cost wearable sensor to measure trunk movement during performance of SWMFT among stroke and age-matched healthy participants.

Methods: An observational cross-sectional study is used to establish the reliability of using the Valedo system to measure the trunk ROM in chronic stroke and age-matched healthy participants during performance of six tasks of SWMFT (hand to box, lift can, lift pencil, fold towel, extend elbow weight, turn key in lock). From March to May 2019 a purposive sample of 20 adult chronic stroke participants with UL impairment (mild to moderate) and 20 aged matched healthy participants will be recruited. All participants will attend two assessment sessions seven to ten days apart. In the first session, the SWMFT will be recorded three times (the first and third assessment by assessor 1, the second assessment by assessor 2) with a rest period between them to test for intra and inter-rater reliability. In the second session, the SWMFT data will be recorded once by assessor 1 to assess between sessions reliability.

Results: Recorded data will be processed using MATLAB software. Subsequently, the trunk ROM during each task will be calculated. Data will be exported into Excel files and analysed using IBM SPSS 24 (SPSS Inc, Chicago, IL). For test re-test and between session reliability, measurements will be tested using the [ICC 1,1] with 95% confidence interval (CI); for inter-rater reliability, the [ICC 1,3] with 95% confidence interval (CI) will be used. Results will be presented at the conference.

Conclusion: Intra and inter-reliability of Valedo system to assess trunk ROM during SWMFT tasks will be established.
