Research project: Development and validation of a reliable instrumented version of Trunk Impairment Scale

Currently Active: 

We want to improve assessment of how well someone can move their trunk after a stroke.


Trunk control and balance problems are common in stroke survivors and these can affect everyday activities, for example when leaning sideways to grasp a salt holder from the other side of a table.

Many studies have shown that stroke survivors use extra trunk movements when using their arms to reach. If this extra movement during reaching continues for a long time, it may also lead to abnormal arm and hand movement, which may limit recovery in the longer term.

Therapists often use the Trunk Impairment Scale (TIS) to assess trunk control. People with stroke are asked to do 17 tasks including static sitting, dynamic sitting and trunk coordination.

We are currently testing if we can make it easier and faster to assess trunk control using an instrumented TIS (iTIS). This involves placing three wearable sensors on the chest and lower spine.

We are testing it with people who have had a stroke, and also with people of the same age who are healthy. We are recording data from the sensors while people are completing the tasks and comparing it with a video recording.
