Extensive rehabilitation after a stroke is highly important to avoid permanent disabilities. Over 60% of stroke survivors experience limited mobility in upper limb. The aim of this study was to explore how smart textiles with sEMG electrodes and bio-feedback can support upper limb stroke rehabilitation by identifying user needs and evaluate these through interviews and a focus group discussion with rehabilitation professionals. A human centred design approach was including semi structured interviews and a focus group discussion. Furthermore, low-mid fidelity prototypes were made. These were evaluated by the professionals. The most significant findings were that the technology must be simple to understand and use, it should motivate the user to perform rehabilitation, and it should enable rehabilitation including functional movements. The final result was two high fidelity prototypes that aimed to meet the three main needs identified from the semi structured interviews. Further-more, the prototypes aimed to enable home based rehabilitation. One of the proto-types targeted the function of fingers and hand which is an important function to increase the freedom and independence of stroke survivors. The second prototype was a full sleeve including electrodes targeting muscles in both forearm and upper arm to enable a wider range of movements in rehabilitation. The technology includes features to guide and support the user. One example tactile elements in the textile to help with correct position of the electrodes. The technology could enable home based rehabilitation which could decrease the high pressure on the healthcare system and save resources in both time and money. Furthermore, it could engage and motivate the patient to increase the rehabilitation outcome and the overall quality of life for stroke survivors.
