SPATIAL

A feasibility study of prisms and therapy in attention loss after stroke.

 

Project outcomes

Some stroke patients have difficulty taking part in therapy because of attention loss (spatial inattention).

SPATIAL is now complete.

We have analysed the findings and would like to share the results with you. We have produced an easy-access summary report which you can download and an audio/video version of the report.

Project background

Our research is testing the feasibility of delivering and investigating an occupational therapy intervention that may improve rehabilitation for stroke survivors with spatial inattention.

Spatial inattention is when the stroke causes poor awareness of one side of their body or the space around them, causing difficulties completing everyday tasks.

Patients with spatial inattention shortly after having a stroke often make a poor recovery. They miss out on the full benefits of early stroke therapy and are often discharged from hospital needing a lot of help at home.

SPATIAL investigated whether it is practical to use an intervention (prism adaptation training) to help patients with spatial inattention to participate in NHS occupational therapy, and how best to design a trial to test effectiveness.

We examined whether prism adaptation training increased engagement in occupational therapy and tested ways of measuring the possible impact on everyday functioning.

SPATIAL was a joint project between staff at The University of Manchester and the University of the West of England. Researchers at the University of the West of England explored the experiences of participating patients, carers and occupational therapists.

The intervention

One possible therapy for inattention is prism adaption training (PAT).

This involves patients wearing glasses with large lenses (prisms) which alter the user’s view to one side.

While wearing the prism glasses, the patient points at a target repeatedly for five minutes in the hope of temporarily adapting the brain.

Once the glasses are removed, the patient switches from pointing too far one side to the other, becoming more aware of their ‘neglected’ side in the process.

This adaptation may help patients to participate in occupational therapy if therapy is delivered immediately after prism training.

 

Project aims

This feasibility project had a number of different aims relating to delivering PAT and measuring patients’ responses.

The main aims were to find out whether:

  • staff can deliver prism adaptation training during occupational therapy;
  • prism adaptation training enhances patients’ ability to take part in occupational therapy;
  • prism adaptation training and the study processes are acceptable to patients and carers;
  • it would be possible to do a future, large, randomised, controlled trial.

 

 

 

 

Further information

Where did the study happen?

Six NHS trusts around the North West of England took part. We estimated we would recruit around 60 stroke patients with spatial inattention, 40 informal carers and approximately 12 occupational therapy staff.

Salford Royal Foundation Trust is was the lead NHS site for this two year study which began on 30 June 2018. Recruitment ended in January 2020.

How did we involve stroke survivors?

We had a dedicated SPATIAL patient advisory group of stroke survivors led by Ann Bamford. They worked in collaboration with us on many aspects including:

  • developing the study design
  • co-writing grant and ethics applications and patient-facing documents
  • raising awareness of the study
  • monitoring study progress
  • helping interpret the findings and planning the next steps

There were also two independent stroke survivor members on our trial steering committee providing overall supervision of the trial.
