Description of intervention(s) / exposure
The condition being observed is the change in muscle stiffness that may occur as a result of a stroke.
The exposure is the Shear Wave Elastography assessment of the muscle stiffness. This is an advanced ultrasound technology that quantitatively determines the stiffness of tissue.
The transducer is placed lightly on the skin at the appropriate level and a measurement is taken. This will be done at three levels, on both arms, with the elbow fully extended and again with the elbow partially bent.

The Shear Wave Elastography assessment will take place twice a week, for the first four weeks after a stroke. Each scanning assessment takes approximately 1 hour. This will be performed by an accredited Senior Sonographer with experience in Shear Wave Elastography.

There will be Aquasonic Gel to facilitate the ultrasound transmission.
There will be paper towel to remove the gel.
There will be a measuring tape and skin-safe marker to mark the correct locations.

Each scanning session will be recorded in the participants hospital chart

Statistical methods / analysis
Using data from comparable research, an alpha value of 0.05 and power of 80%, a minimum sample size of 6 participants is required. While this is the minimum number, this project aims to recruit and collect data on at least 36 participants in the data collection period (approximately 40 weeks). As it is not known which participants will go on to develop a change in muscle stiffness, a convenience sample of every eligible patient will be approached for recruited.
Statistical analysis will be descriptive, inferential and exploratory. The exploratory analysis is to assist in getting insights on the patterns over time.
