A feasibility study conducted by Sunnaas Rehabilitation Hospital in Norway shows that patients with TBI might benefit from using new technology in their rehabilitation.Long-time hospitalization and long-time immobilization can have a negative effect on muscles and skeletal systems, lungs, heart, digestive system and to orthostatic dysfunction. Research within mobilization of patients in the early rehabilitation phase has increased dramatically the last years.
This research suggests that early mobilization leads to a shorter stay in the hospital, less extent of contractures in muscles and joints, and improved functions in general. Studies have also shown that early mobilization affects the patient’s level of consciousness positively.
What is Traumatic Brain Injury (TBI)?
TBI is a diffuse and complex neurological injury (often multi-trauma injury) resulting in sensory, motor and cognitive impairments and disabilities. TBI usually affects large parts of the body, and might lead to relatively long hospitalization periods. The most frequent cause of TBI is falling, followed by road traffic accidents. The Glasgow Coma Score (GCS) is used to grad a patient’s level of consciousness, classifying the injury as mild, moderate or severe. A mild brain injury will in most cases require rest and medication to relieve headache, while moderate to severe TBI requires intensive care in a hospital.
Static standing table versus dynamic standing
Until recently the main intervention for mobilization after traumatic brain injury has been the use of tilt tables, in-bed cycling and manual mobilization by manpower. New innovative technology is now on the market, and a more dynamic type of standing is available, also for patients with TBI.
Sunnaas Rehabilitation Hospital in Norway is the largest specialist hospital in the country within the field of physical medicine and rehabilitation. The Hospital provides multidisciplinary rehabilitation for patients with complex functional impairment following illness or injury.
Sunnaas’ department for traumatic brain injury has since 2014 been involved in a research and development project together with Made for Movement. The aim of the project has been to test the Innowalk Pro, which is a robotic rehabilitation trainer allowing patients with severe disabilities to stand and move. They have been testing the device on patients with head injuries, with the purpose of:
- Conducting a feasibility study on the early mobilization of patients with TBI
- Contributing to the development of a product adapted to adult patients
The project has been supported by Innovation Norway.
Results from the Sunnaas project
The overall experiences from the project have, from a clinical physiotherapy perspective, been very positive as the device has made it possible to mobilize severely injured patients in a safe way.
The patients are during the early stage in need of shielding, and most of the therapy and stimulation of the patients take place in their rooms. Due to the Innowalk Pro’s size it has been possible to move the device into the patient’s room and mobilize the patient there.
Observations of the patients using the device have shown the following:
- Patients show positive reactions while moving their legs in the device. The patients often react by smiling.
- Patients with agitated behaviour become calmer during active standing in the Innowalk Pro compared to static standing in standing tables.
- Patients with reduced levels of consciousness, increase their alertness during active standing in the Innowalk Pro. They stay awake and open their eyes for a longer time.
“It reminds me of the training I used to do in a cross-trainer. I felt my body better, it feels more alive standing in the Innowalk Pro”
- Patient in the Innowalk Pro
The department, who has been involved in using the device, experienced an opportunity to provide more variation in the treatment offering during rehabilitation. They also found that the Innowalk Pro contributed to a more active approach compared to traditional static standing. No negative or adverse events were registered in the project period.
Several patients who have used the device during the rehabilitation period have gained the ability to walk independently before being discharged from the hospital. Some patients who have not gained the ability to walk and want to continue the activity in the Innowalk Pro, have had the option of applying for an individual Innowalk for home use.
