New study to investigate how sleep can aid stroke recovery

Researchers at the University of East Anglia are launching a new study to see how sleep can help stroke recovery.

They will investigate whether people’s sleep patterns influence recovery of neuromuscular function - the ability to use weak muscles in the right order and at the right time during movement.

The team are looking for people who have had a stroke to take part, and they hope their findings will reveal how the brain recovers after a stroke.

A stroke happens when the blood supply to part of the brain is cut off, killing brain cells. Damage to the brain can affect how the body works – and weakness on one side of the body is the most common and well-known effect of stroke. If your muscles are weak, you are likely to have some difficulty moving your limbs and moving around in general. We want to better understand how the brain recovers after a stroke - so we will be investigating how stroke survivors regain movement, and how this is influenced by sleep and time. We hope to find out more about sleep patterns that are beneficial for movement recovery after stroke.”

Lead Researcher Prof Valerie Pomeroy, UEA’s School of Health Sciences.

The team are looking for people in the region who have had a stroke to take part in the study. Participants will undertake measures of daily activity, sleep and movement.

The project will involve measuring people’s movement using small sensors placed on the skin’s surface that record natural muscle activity whilst they carry out a daily task - picking up a telephone.

Participants will be asked to attend two visits at UEA. These visits normally require one and a half to two hours each. During the visits participants will undertake the movement measures and complete questionnaires about how they sleep. 

In-between visits, participants will wear a motion watch on each wrist for seven days to measure their everyday activity at home.

Prof Pomeroy said: “There is strong evidence that physiotherapy improves the ability of people to move and be independent after a stroke.  But at six months after stroke many people remain unable to produce the movement needed for everyday activity such as answering a telephone. 

“We are undertaking this study to understand more about whether this situation could be improved by using interventions to change a patient’s sleep pattern and thus improve recovery of movement ability.”
